Answers

Answer 1
Here's how I got the answer
Tim Earned $16 Babysitting And $17.50 Mowing A Lawn. He Paid $8.50 For A Movie And Bought A Small Popcorn
Answer 2

The expression to show how much money he has left is  $(33.5 - 10.45).

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given that, Tim earned $16 babysitting and $17.50 mowing a lawn.

What Tim has earned we'll add which is $(16 + 17.50) = $33.5.

He paid $8.50 for a movie and bought a small popcorn for $1.95.

His spendings we'll also add which is $(8.5 + 1.95) = $10.45.

Now, to write an expression for how much money he has left we'll subtract

his total spending from his total earnings which is,

= $(33.5 - 10.45).

= $23.05.

therefore

the answer is

The area of the triangle is [tex]18\ units^{2}[/tex]

Final answer:

The area of the triangle with given vertices is 18 units squared.

Explanation:

To find the area of a triangle with given vertices, we can use the formula:

Area =  1/2 * |(x1 * (y2 - y3) + x2 * (y3 - y1) + x3 * (y1 - y2))|

Plugging in the coordinates of the vertices:

A = 1/2 * |(-2 * (3 - (-5)) + 4 * (-5 - 1) + (-2) * (1 - 3))|

Simplifying the expression:

A = 1/2 * |(-2 * 8 + 4 * (-6) + (-2) * (-2))|

A = 1/2 * |(-16 - 24 + 4)|

A = 1/2 * |-36|

A = 1/2 * 36

A = 18

Therefore, the area of the triangle is 18 units squared.

4) 3y=7x-1

3) what is the direct variation equation if y=8 and x = 4?

4) what is the direct variation equation if y =-5 and x = 7 /

Answers

1. where is the y intercept of any direct variation equation?

A direct variation equation is one in which the general form is:

y = k x

where k is the constant of proportionality

 

The y-intercept in this case is therefore zero so it is located on the origin (0, 0)

 

2. The equation which is a direct variation is:

                3) 3x-7y=0

                Because we can write this as:

                y = (3/7) x

 

3. what is the direct variation equation if y=8 and x = 4?

We solve for the value of k since we know that:

k = y/x

k = 8/4 = 2

So the equation is:

y = 2x

 

4. what is the direct variation equation if y =-5 and x = 7?
We also solve for the value of k since we know that:

k = y/x

k = -5/7

So the equation is:

y = (-5/7) x

In what time will $400 amount to $512 if the simple interest is calculated at 14% p.a.

Answers


The time is 2 years:

Important variables to know:
A= Amount
P = Principal
I = simple Interest
T = time in years
R = rate in years

Formulas:
A = P + I
I = PRT

What we have? Amount ($512), Principal ($400), Rate (14%)
What we need? Time and Interest (simple interest)

So, first let's find the interest.

512 = 400 + I
Subtract 400 from both sides.
I = 112

Then plug that into the second formula:
112 = 400*.14(T)
Multiply 400*.14= 56
112 = 56T
Divide both sides by 56
T = 2 years

You are asked to draw an equiangular rhombus, an equilateral rectangle, and a parallelogram with four right angles. will all three figures be squares?

Answers

No, only the equilateral rectangle will be a square because equilateral means equal-sided. The equiangular rhombus will only have equal angles but may be a rectangle, and the parallelogram with four right angles may also be a rectangle.

All the three figures given in the problem cannot be squares.

What is a parallelogram?

A parallelogram is a type of quadrilateral of which the opposite sides are equal and parallel. A diagonal of a parallelogram divides it into two congruent triangles.

Given that,

There are an equiangular rhombus, an equilateral rectangle, and a parallelogram with four right angles.

They can be explained one by one as follows,

(a) A rhombus has all the four sides as equal and its opposite sides are parallel.

When all the angles of a rhombus becomes equal, its each angle is a right angle.

It implies that it will have all angles equal to right angle and all sides are equal as well.

Thus, an equiangular rhombus is a square.

(b) A rectangle has all its angle equal to right angle.

Opposite sides are equal and parallel.

When all the sides become equal, it will be a square.

(c) A parallelogram has its opposite sides as  equal and parallel.

When all the angles become right angles, it can be a rectangle.

Hence, an equiangular rhombus and an equilateral rectangle can be a square but a parallelogram with four right angles cnnot be so.

What is the coefficient of the fourth term in the expansion of (x + 3)4?

Answers

the answer is 4 bc it is being distributed to the x and the 3

Final answer:

The coefficient of the fourth term in the expansion of (x + 3)⁴ is calculated using the binomial theorem, which results in a coefficient of 108.

Explanation:

To find the coefficient of the fourth term in the expansion of (x + 3)⁴, we can use the binomial theorem. The binomial theorem states that when a binomial is raised to a power, the expansion consists of terms in the form of [tex]C(n, k) \times a^{n-k} \times b^k[/tex], where C(n, k) is the binomial coefficient. In our case a = x and b = 3, and n = 4.

For the fourth term where k = 3, the term would be [tex]C(4, 3) \times x^{4-3} \times 3^3[/tex]. The binomial coefficient C(4, 3) is equal to 4 because there are four ways to choose three items out of four. Therefore, the coefficient is 4 × 3³ = 4 × 27 = 108. So, the coefficient of the fourth term in the expansion of (x + 3)⁴ is 108.

What is an angle?

An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.

An angle bisector is defined as a ray, segment, or line that divides a given angle into two angles of equal measures.

Steps to Construct an Angle Bisector:

Step 1: Draw any angle, say ∠ABC.

Step 2: Taking B as the center and any appropriate radius, draw an arc to intersect the rays BA and BC at, say, E and D respectively. (Refer to the figure below)

Step 3: Now, taking D and E as centers and with the same radius as taken in the previous step, draw two arcs to intersect each other at F.

Step 4: Join B to F and extend it as a ray. This ray BF is the required angle bisector of angle ABC.

Step 2: Taking B as the center and any appropriate radius, draw an arc to intersect the rays BA and BC at, say, E and D respectively. (Refer to the figure below)

Use the unit circle to find tan sin 90

b.0
c.-1
d.undefined

Answers

[tex]sin(90)=1\\tan(90)=\pm\infty[/tex].

The answers are [tex]a[/tex] and [tex]d[/tex] respectively.

To evaluate tan(sin(90°)), first determine sin(90°) which equals 1. However, tan(1) is not a standard unit circle value, and if the question intended to find tan(90°), this would be undefined.

The correct option is (d).

The question is asking to use the unit circle to find the value of tan(sin(90°)).

Firstly, the sin(90°) on the unit circle is 1, as the sine function corresponds to the y-coordinate of the unit circle at that angle. Therefore, sin(90°) = 1.

Now, we need to find the tangent of this value, which is tan(1). However, tan(1) is not solvable by standard unit circle values, so it seems we may have a misunderstanding in the question. If the intention was to find tan(90°) instead, then the answer would be undefined as the tangent function at 90 degrees is undefined due to division by zero.

Which expression is equal to 3√54−4√24 ?

Answers

Final answer:

The expression 3√54−4√24 simplifies to √6 after factoring out the perfect squares under the radicals and combining like terms.

Explanation:

The student's question requires simplifying the expression 3√54−4√24. To simplify a square root, we look for perfect squares that are factors of the number under the root. For √54, we can notice that 54 = 9 * 6, and since √9 is a perfect square, we have 3√54 = 3*√9*√6 = 3*3*√6 = 9√6. Similarly, for √24, it is 24 = 4 * 6, so √24 = √4*√6 = 2*√6, and thus -4√24 = -4*2*√6 = -8√6. Combining these two results, we have 9√6− 8√6, which simplifies to √6. Therefore, the simplified expression is √6.

Hope I helped :) 
First of all you need to rearrange the equation to slope-intercept form which is y = mx+b.
so; 4x - 3y = 12.3 will be
 -3y = 12.3 - 4x
rearrange so it will be easy to isolate your y.
-3y = -4x + 12.3
divide both sides by -3
-3y/-3 = -4x/-3 + 12.3/-3
y = 4x/3 - 4.1
so: slope 'm' = 4x/3
      y-intercept = -4.1
      x-intercept = 0

 Lines PQ and RS do not have a fixed length.
 Angle PTR and angle PTS are supplementary angles. 
Lines PQ and RS intersect at an angle less than a right angle.
 
Angle PTR and angle PTS are complementary angles.

Answers

The logic is a bit circuitous/confusing but the best answer is:
"Angle PTR and angle PTS are supplementary angles.".

This means that PQ and RS are straight lines, and that their angles follow the properties or supplementary angles, and opposite angles. 

This implies the more relevant detail that PTR and STQ are opposite angles, and opposite angles are always equal. 

Answer:

B. Angle PTR and angle PTS are supplementary angles.

Step-by-step explanation:

As R, T, S are collinear and PQ intersects RS at T, so ∠RTP and ∠STP are supplementary angles.

[tex]\Rightarrow m\angle RTP+m\angle PTS=180^{\circ}[/tex]  -------1

As P, T, Q are collinear and RQ intersects PQ at T, so ∠PTS and ∠QTS are supplementary angles.

[tex]\Rightarrow m\angle PTS+m\angle QTS=180^{\circ}[/tex]  ------2

Subtracting equation 1 and 2,

[tex]\Rightarrow m\angle RTP+m\angle PTS-m\angle PTS-m\angle QTS=180^{\circ}-180^{\circ}[/tex]

[tex]\Rightarrow m\angle RTP-m\angle QTS=0[/tex]

[tex]\Rightarrow m\angle RTP=m\angle QTS[/tex]

[tex]\Rightarrow m\angle PTR=m\angle STQ[/tex]

Therefore, to prove that angle PTR is always equal to angle STQ the statement needed is angle PTR and angle PTS are supplementary angles.

Kathryn draws three pairs of intersecting lines. In each figure, she measures a pair of angles.

When a pair of lines intersect, all of the angles formed are right angles. When a pair of lines intersect, the vertical angles are congruent. When a pair of lines intersect, all of the angles formed are congruent.

Answers

Inductive reasoning is that when two lines intersect you will always have a pair of congruent angles considering an exception when all the angles are congruent. According to this,
1) Vertical angles (or opposite angles) are congruent. In this case, vertical angles could be acute or obtuse depending on the position of the lines.

2) The second case is the exception when all the angles are equal. It means that the lines are perpendicular.

3) Again back to the first case, vertical angles are equal or congruent in other words.

4) And again back to the second case when the lines are perpendicular, then all the angles that formed are equal to each other.

You can observe all the cases in the picture attached below.
Answer:

The reasonable conjecture for Kathryn to make by recognizing a pattern and using inductive reasoning is:

  When a pair of lines intersect, the vertical angles are congruent.

Step-by-step explanation:

The vertical angles are the opposite angles that are formed by the intersection of two lines. They are also known as Vertically opposite angles.

We know that when a pair of lines intersect then the vertical angles are always congruent.

However the measure of the angles may be acute or obtuse or right angle.

Answer:

1.16 in

2.24 in

3.12.8 in

Step-by-step explanation:

We are given that

Width of photo=5 in

Length of photo=8 in

We have to find the length of new photo in each case.

1. Let x represent the width and y represents the length of photo.

When width increase then length of photo is also increases then it is direct proportion.

[tex]\frac{x_1}{y_1}=\frac{x_2}{y_2}[/tex]

Substitute the values then we get

[tex]\frac{5}{8}=\frac{10}{y}[/tex]

[tex]y=\frac{10\times 8}{5}=16[/tex]

Hence, the length of photo=16 in

2.Width=x=15 in

Again using the formula

[tex]\frac{5}{8}=\frac{15}{y}[/tex]

[tex]y=\frac{15\times 8}{5}=24[/tex]

Hence, the length of new photo=24 in

3. Width =x=8 in

Substitute the values in the given formula

[tex]\frac{5}{8}=\frac{8}{y}[/tex]

[tex]y=\frac{8\times 8}{5}=\frac{64}{5}=12.8[/tex]

Hence, the length of new photo=12.8 in

Given that, two chords are the same distance from the center of a circle.

What is the chord on a circle?

The chord of a circle is a line that connects two points that are located on the circumference of the circle. These two points can be located anywhere on the same circumference.

Chords are equidistant from the center if and only if their lengths are equal. Equal chords are subtended by equal angles from the center of the circle.

Hence, if two chords are the same distance from the center of a circle then they are congruent.

Lisa and Bart spin this spinner 60 times the result are below/ black=17 blue=15 orange=21 purple=7 a. What is the experimental probability of a spin of orange? B which color had an experimental probability that matched its theoretical probability

Answers

a) 35% because 21÷60= 0.35
b) blue because each color has the theoretical probability of 25%. 15÷60=0.25

[tex]\text{Answer: a) }P(\text{ getting an orange )}=\frac{7}{20}[/tex]

b) Blue color had an experimental probability that matched its theoretical probability.

Explanation:

Since we have given that

Number of times this spinner is spinned = 60

Number of times black occur = 17

Number of times blue occur = 15

Number of times orange occur = 21

Number of times purple occur = 7

a) So, Experimental probability of a spin of orange is given by

[tex]P(\text{ getting an orange }=\frac{\text{ Number of times orange occur}}{\text{total number of times the spinner spins}}\\\\P(\text{ getting an orange})}=\frac{21}{60}=\frac{7}{20}[/tex]

b) which color had an experimental probability that matched its theoretical probability.

According to theoretical probability ,

Every event must have equal probability, i.e. [tex]\frac{1}{4}[/tex]

And,

[tex]P(\text{ getting blue color)}=\frac{15}{60}=\frac{1}{4}[/tex]

So, Blue color had an experimental probability that matched its theoretical probability.

We are met on a great battlefield of that war.(2) We have come to dedicate a portion of that field as a final resting place for those who here gave their lives that this nation might live. It is altogether fitting and proper that we should do this. But, in a larger sense, we cannot dedicate ... we cannot consecrate ... we cannot hallow this ground.

The world will little note, nor long remember, what we say here, but it can never forget what they did here.What does President Lincoln imply by the line in bold?
