Answer:

The coordinates of her new position are (0 , -5) ⇒ answer B

Step-by-step explanation:

* Lets revise some translation

- If the point (x , y) translated horizontally to the right by h units

 then the new point = (x + h , y)

- If the point (x , y) translated horizontally to the left by h units

 then the new point = (x - h , y)

- If the point (x , y) translated vertically up by k units

 then the new point = (x , y + k)

- If the point (x , y) translated vertically down by k units

 then the new point = (x , y - k)

* Now lets solve the problem

∵ Nancy start from position (2 , -3)

- She walks 5 blocks to the right and 3 blocks down

∴ Add x-coordinate by 5 and subtract y-coordinate by 3

∵ The starting position is (2 , -3)

∴ The new position is (2 + 5 , -3 - 3) = (7 , -6)

- She walks 7 blocks to the left and 1 block up

∴ Subtract x-coordinate by 7 and add the y-coordinate by 1

∴ The new position is (7 - 7 , -6 + 1) = (0 , -5)

* The coordinates of her new position are (0 , -5)

Answer:

17 dimes, 21 quarters

Step-by-step explanation:

I suppose you want to know how many dimes and quarters she had in her jar.

Let's say x = dimes and y = quarters.

We can make the following 2 equations:

1) x + y = 38 (number of coins in the jar)

2) 10x + 25y = 695 (a number of dimes plus a number of quarters sum up to 695 cents)

From 1), we can isolate y: y = 38 - x, and place that value in the second equation:

10x + 25y = 695

10x + 25 (38 - x) = 695

10x + 950 - 25x = 695, then we subtract 950 on both sides and simplify

-15x = -255

x = 17

So, Jenna had 17 dimes.

y = 38 - x, so y = 38 - 17 = 21

And she had 21 quarters.

Answer:

x = 6

Step-by-step explanation:

Since the line segment is an angle bisector then the following ratios are equal

[tex]\frac{42}{78}[/tex] = [tex]\frac{6x-1}{10x+5}[/tex] ( cross- multiply )

78(6x - 1) = 42(10x + 5) ← distribute parenthesis on both sides )

468x - 78 = 420x + 210 ( subtract 420x from both sides )

48x - 78 = 210 ( add 78 to both sides )

48x = 288 ( divide both sides by 48 )

x = 6

The radius of the sphere is 5 units

Step-by-step explanation:

The volume of the sphere with radius r is given by the formula;

[tex]volume=\frac{4}{3}*\pi*r^{3}[/tex]

The volume of the sphere is given as;  500/3 π cubic units

We substitute this value into the formula and solve for r;

[tex]\frac{500}{3}\pi=\frac{4}{3}*\pi*r^{3}\\\\r^{3}=\frac{500}{4}\\\\r=\sqrt[3]{125}=5[/tex]

Answer:

The correct answer is second option

The radius of sphere = 5 units

Step-by-step explanation:

Points to remember

Volume of sphere = (4/3)πx³

Where 'x' is the radius of sphere.

To find the radius of sphere

We have volume is  500/3 π cubic units

(4/3)πx³ = 500/3 π

x³ = (500/3) * (3/4)

 = 500/4 = 125

x = ³√125

x = 5 units

The correct answer is second option

The radius of sphere = 5 units

Step-by-step explanation:

4x = 32 - x2 would be much clearer if written as 4x = 32 - x^2.  Please use

" ^ " to indicate exponentiation.

Rewrite 4x = 32 - x^2 in the standard form of a quadratic:  x^2 + 4x - 32

Then the coefficients are a = 1, b = 4 and c = -32.

Find the discriminant.  It is b^2-4ac.  

Here, b^2-4ac = 4^2 - 4(1)(-32), or 16 + 128, or 144.

Because the discriminant is positive, we know immediately that this quadratic has two real, unequal roots.

So, the answer to this question is "the graph of 4x = 32 - x^2 cross the x-axis in two places."

To find the time for Car X to be 5 laps ahead of Car Y, we calculate the difference in laps completed per minute (0.25 laps) and divide the target difference (5 laps) by this rate, which gives us 20 minutes.

The question asks how long it will take for Car X to be 5 laps ahead of Car Y if Car X makes one lap every 60 seconds and Car Y every 80 seconds. To solve this, we need to find the difference in laps completed by the two cars over time, until Car X is 5 laps ahead. Since Car X is the faster car, it takes one lap less time than Car Y to complete a lap.

First, we find out how many laps Car X completes more than Car Y in one minute:

The difference in the number of laps per minute is 1 lap - 0.75 laps = 0.25 laps per minute for Car X compared to Car Y.

Next, we calculate the time it will take for Car X to be 5 laps ahead:

Therefore, it will take 20 minutes for Car X to be 5 laps ahead of Car Y.

Hope it will find you well.

Answer:

Yes

Step-by-step explanation:

It can be 6 units. The rule relating to the sides of the triangle is that you should be able to add two sides and get a length that is longer than the third side. You usually add the lower two numbers because it basically says that it will work for all sides but, if you're still in doubt you just have to compare the numbers.

For Example

3+5 is greater than 6

5+6 is greater than 3

6+3 is greater than 5.

All of these makes sense so 6 can be a possible answer.

In triangle EFG, it is not possible for segment GE to measure 6 units.

No, it is not possible for segment GE to measure 6 units in triangle EFG.

In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

Since segment EF measures 3 units and segment FG measures 5 units, the sum of these two sides is 8 units, which is less than 6 units. Therefore, segment GE cannot be 6 units long in triangle EFG.

Answer:

The statement most accurately describes the figure is AB > DB ⇒ A

Step-by-step explanation:

* Lets describe the figure

- AD intersect EC at point B

- There are two triangles ABE and DBC

- B is the mid-point of EC

- AD bisects EC

- EB = BC

- AE = DC

- m∠AEB = 30°

- m∠DCB = 27°

∵ The measure of angle AEB is greater than the measure of

   angle DCB

∴ The opposite side to the angle AEB is longer than the opposite

   side of angle DCB

∵ AB is the opposite side to angle AEB

∵ BD is the opposite side to angle DCB

∴ AB is longer than BD

∴ AB > DB

* The statement most accurately describes the figure is AB > DB

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cutoff point with the y axis

To find the slope two points are needed through which the line passes:

[tex]m = \frac {y2-y1} {x2-x1}\\m = \frac {8-8} {- 5 - (- 2)} = \frac {0} {- 5 + 2} = \frac {0} {- 3} = 0[/tex]

THE equation is of the form:

[tex]y = b[/tex]

We substitute the y coordinate of the point (2,8)

[tex]8 = b[/tex]

Then, [tex]y = 8[/tex]

Answer:

Zeros of a quadratic equation ax² + bx + c = 0

x = [-b ± √(b² - 4ac)]/2a

To find the zeros of given quadratic equation

It is given that,

6x² +12x - 7 = 0

Here a = 6, b = -12 and c = -7

x = [-b ± √(b² - 4ac)]/2a

 =  [-12 ± √(12² - 4*6*(-7))]/2*6

 = [12 ± √(144 +168 )]/12

The correct expression that represents her father's age is A.[tex]\(3x - 4\).[/tex]

To arrive at this conclusion, let's analyze the given information:

Marcy determined that her father's age is four less than three times her age. Let's denote Marcy's age as x. According to the statement, her father's age can be expressed as three times Marcy's age minus four years.

Mathematically, this can be written as:

[tex]\[ \text{Father's age} = 3 \times \text{Marcy's age} - 4 \][/tex]

Substituting x for Marcy's age, we get:

[tex]\[ \text{Father's age} = 3x - 4 \][/tex]

Now, let's evaluate the other options to confirm that they are incorrect:

B. x - 4: This expression suggests that the father's age is four years less than Marcy's age, which does not match the given information that the father's age is four less than three times Marcy's age.

C. 4x - 3: This expression indicates that the father's age is three years less than four times Marcy's age, which again does not align with the given information.

D. 4 - 3x: This expression would imply that the father's age is calculated by subtracting three times Marcy's age from four, which is not the relationship described in the problem.

Therefore, the only expression that correctly represents the father's age based on the given information is A. [tex]\(3x - 4\).[/tex]

There are 12 multiple choice

Step-by-step explanation:

Let m = multiple choice

f = free response

f+m = 15 since there are 15 questions

3m+5f = 51  since we have 51 minutes and 3 for multiple choice and 5 for free response

We have 2 equations and 2 unknowns

m+f = 15

3m+5f = 51

Multiply the first equation by -3

-3(m+f) = -3*15

-3m -3f = -45

Add this to the second equation

-3m-3f = -45

3m+5f = 51

---------------------

        2f = 6

Divide by 2

2f/2 = 6/2

f = 3

There are 3 free response.

m+f = 15

m+3 = 15

Subtract 3 from each side

m+3-3=15-3

m=12

Step-by-step explanation:

A term in a polynomial is a single number or a number multiplied by any number of variables. A polynomial is a sum of terms.

The only thing that can be done with variables in a polynomial is to multiply them by numbers or other variables. In a polynomial, you cannot: divide by a variable (have a variable in a denominator), have a root of a variable, have a log of a variable, have a variable as an exponent, etc.

All expressions are polynomials except for D. In D., the negative exponents mean division by variables.

Fraction: 70/100

Decimal: 0.7

Percent: 70%

Answer:

The answer is:

Fraction: 7/10

Decimal: 0.7

Percent: 70

Step-by-step explanation:

There are 70 colored squares and 100 squares in total. The fraction is 70/100, which can be simplified to 7/10.

One way to convert the fraction 7/10 to decimals is to divide the numerator (7) by the denominator (10). That gives you the decimal 0.7.

A way you can convert the decimal to percent is to multiply 0.7 by 100. You get 70%. Also, there are 70 colored squares out of 100, so that equals 70%.

I hope this helped! :)

Answer:

$1.10

Step-by-step explanation:

1 ft = 0.3048 m

3 ft = 3 * 1 ft = 3 * 0.3048 m = 0.9144 m

$1.20/m * 0.9144 m = $1.09728

Answer: $1.10

Answer:

$ 1.08

Step-by-step explanation:

1 feet = 12 inches

so, 3 feet = 12 x 3 = 36 inches

1 metre = 40 inches

Cost of 1 m of fabric = $ 1.20

cost of 40 inches of fabric = $ 1.20

Cost of 1 inch of fabric = $ 1.20 / 40 = $ 0.03

Cost of 36 inches of fabric = $ 0.03 x 36 = $ 1.08

Thus, the cost pf 3 feet fabric is $ 1.08

Check the picture below.

recall the ambiguous SSA case, as the "12" side moves, it ends up with two supplementary angles on the base.

Answer:

see explanation

Step-by-step explanation:

Given

x + 4y = 36

To find the x- intercept, let y = 0 in the equation and solve for x

x + 0 = 36 ⇒ x = 36 ← x- intercept

To find the y- intercept let x = 0 in the equation and solve for y

0 + 4y = 36 ⇒ y = 9 ← y- intercept

Answer:

x-intercept is 36; y-intercept is 9.

Step-by-step explanation:

Given equation of the line,

[tex]x+4y=36[/tex]

For x-intercept ( the point at which the line intersects the x-axis ),

y = 0,

[tex]\implies x+4(0) = 36[/tex]

[tex]x=36[/tex]

⇒ The value of x-intercept is 36,

Now, for y-intercept( the point at which the line interests the y-axis )

x = 0,

0 + 4y = 36

⇒ y = 9

⇒ The value of y-intercept is 9.

Hence, first option is correct.
