23 + 5 × 10 ÷ 2 – 33 + (11 – 8)

A. 9
B. 41
C. 10
D. 55

Answer:

yes

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (- 3, 2), so

(x + 3)² + (y - 2)² = r²

r is the distance from the centre to a point on the circle

Calculate r using the distance formula

r = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (- 2, 9)

r = [tex]\sqrt{(-2+3)^2+(9-2)^2}[/tex] = [tex]\sqrt{1^2+7^2}[/tex] = [tex]\sqrt{50}[/tex], hence

(x + 3)² + (y - 2)² = 50 ← equation of circle

Substitute (- 10, 3) into the left side of the equation and if equal to the right side then the point lies on the circle

(- 10, 3) : (- 10 + 3)² + (3 - 2)² = (- 7)² + 1² = 49 + 1 = 50

Hence (- 10, 3) lies on the circle

ANSWER

Yes, f is a function.

EXPLANATION

The domain of the relation is D = {xlx is a state in the United States}

The rule is that f(x) ="the state capital"

The relation will be a function if and only if no two elements in the first set have the same image in the second set.

Since no two states will have the same capital, the relation is a function.

Answer:

40

Step-by-step explanation:

Just look up the conversion factor and set up the proportion.

1 dm = 1/10 th of a meter

x dm = 4 meters.                  Cross multiply.

1 dm * 4m = x * 1/10 of a meter. Change 1/10 to a decimal.

1 dm * 4 m = x * 0.1 m                  Divide by 0.1

1 dm * 4 m /0.1 m = x

x = 40 dm

Consider a striking deviation as an outlier (Something that stands out in a pattern, EX: 2, 3, 4, 4, 4, 5, 5, 10 where the outlier would be 10.) Because there is a piece of data at 25-30 minutes that deviates (Or, separates, in a way), it would be considered an outlier (Or, a Striking deviation). Using this information, we can conclude that the answer would be A: 25-30 minutes.

Answer:approximatly 800 inches is the distance between Scott and Steve

Step-by-step explanation: 40 revolutions * 20 inches

The approximate distance between Scott and Steve is 2513.27 inches.

In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.

Each revolution of the bicycle tire covers a distance equal to the circumference of the tire, which is equal to pi times the diameter of the tire.

The distance travelled by the bicycle tire for 40 full revolutions is:

Distance = 40 x π x 20 inches

Distance ≈ 2513.27 inches

Therefore, the approximate distance between Scott and Steve is 2513.27 inches.

To solve the problem, we need to find the area of the triangle, and then find 2/3 of that triangle.

The equation to find the area of a triangle is bh1/2 or base*height*1/2.

Now substitute the known values.

24*16*1/2

Solve

24*8

192.

Now, the easiest way to find 2/3 of a number is to divide that number by 3 and multiply the answer by 2.

192/3=64

64*2=128

Omar kept 128 square centimeters of the flag.

Hope this helps!

[tex] \frac{16 \times 24}{2} = \frac{384}{2} = 192[/tex]

192 is the total area of the triangle; since he kept 2/3 of the flag divide the area by three and times it by two:

[tex]192 \div 3 = 64 \times 2 = 128[/tex]

answer is 128cm^2

Answer:

Option A.

Step-by-step explanation:

The given sequence is 1.5, 3, 6............

We will check first whether the the given sequence is arithmetic or geometric.

For arithmetic sequence

[tex]a_{2}-a_{1}=3-1.5=1.5[/tex]

[tex]a_{3}-a_{2}=6-3=3[/tex]

1.5 ≠ 3, therefore, the given sequence is not an arithmetic sequence.

For geometric sequence

[tex]\frac{a_{2} }{a_{1} }=\frac{3}{1.5}=2[/tex]

[tex]\frac{a_{3} }{a_{2} }=\frac{6}{3}=2[/tex]

2 = 2, therefore, sequence is geometric.

For geometric sequence explicit formula is defined as

[tex]a_{n}=a_{1}(r)^{n-1}[/tex]

[tex]a_{7}=1.5(r)^{7-1}[/tex]

              = [tex]1.5(2)^{6}=96[/tex]

Answer:

(y + 1)

Step-by-step explanation:

Given

5y² + 4y - 1

To factorise the quadratic

Consider the factors of the product of the coefficient of the y² term and the constant term which sum to give the coefficient of the y- term

product = 5 × - 1 = - 5 and sum = + 4

The factors are + 5 and - 1

Use the factors to split the y- term

5y² + 5y - y - 1 ( factor the first/second and third/fourth terms )

= 5y(y + 1) - 1(y + 1) ← factor out (y + 1) from each term

= (y + 1)(5y - 1)

The figure is separated into triangles.

The triangle has a base of 8 inches and a hypotenuse of 10 inches.

Using the Pythagorean theorem solve for the height of the triangle:

10^2 = 8^2 + x^2

100 = 64 + x^2

x^2 = 100-64

x^2 = 36

x = √36

x = 6

The height of the triangle is the width of the rectangle and the length of  the rectangle is 2 triangle bases ( 8 * 2 = 16)

Area of a rectangle is L x W = 6 x 16 = 96 square inches.

Answer:

$3.52 or $3.53

Step-by-step explanation:

We know that he is paying $2.35 per pound, and that he is buying 1.5 pounds worth of pears. Simply multiply 2.35 times 1.5 to get your answer, depending on how far you round, which is 3.52 or 3.53.

1 pound = $2.35

Leo bought 1 pound and 0.5 of a pound (half of a pound). To find how much 0.5 of a pound costs divide 2.35 (the cost of one full pound) by two

2.35 ÷ 2 = 1.18

so...

1 + 0.5 = 1.5

and

2.35 + 1.18 = 3.53

Leo spent $3.53 on 1.5 pounds of pears

Answer:

2) 33

Explanation:

First, identify x.

3x+1=17

3x=16

X=16/3

Then substitute x in the expression.

6x+1=?

6(16/3)+1=?

32+1=?

33=?

So, the answer is #2.

When the equation 3x + 1 equals 17, the value of x is 16/3. Substituting this value of x into the expression 6x + 1 results in an answer of 33.

The subject of the question is Mathematics and it appears to be at a High School level. Given the equation 3x + 1 = 17, we can first solve for x by subtracting 1 from both sides resulting in 3x = 16 and then dividing both sides by 3 which gives x = 16/3. Then we can substitute this value of x in the expression 6x + 1 giving us 6*(16/3) + 1 which simplifies to 32 + 1 = 33. So, the value of the expression 6x + 1 is 33 when the value of the expression 3x + 1 is 17.

Answer:

Option C) similar; SSS similarity; ΔABC

Step-by-step explanation:

we know that

The SSS similarity state : If the corresponding sides of two triangles are proportional, then the two triangles are similar

In this problem

80/30=56/21=72/27

2.67=2.67=2.67 -----> is true

therefore

The triangles STU and ABC are similar by SSS similarity

Answer:  The correct option is

(C)  similar; SSS similarity; ΔABC.

Step-by-step explanation:  We are given to check whether the pair of triangles in the figure are similar to each other or not.

If so, we are to complete the similarity statement.

From the figure, we note that

the lengths of the sides of triangle STU are

ST = 72, TU = 80 and SU = 56.

And, the lengths of the sides of triangle ABC are

AB = 27, BC = 30 and AC = 21.

So, we get

[tex]\dfrac{ST}{AB}=\dfrac{72}{27}=\dfrac{8}{3},\\\\\\\dfrac{TU}{BC}=\dfrac{80}{30}=\dfrac{8}{3},\\\\\\\dfrac{SU}{AC}=\dfrac{56}{21}=\dfrac{8}{3}.[/tex]

That is,

[tex]\dfrac{ST}{AB}=\dfrac{TU}{BC}=\dfrac{SU}{AC}=\dfrac{8}{3}.[/tex]

Therefore, the corresponding sides of the two triangles are proportional.

Hence, triangle ABC and STU are similar by SSS similarity.

Option (C) is CORRECT.  

Answer:

The area of the base is [tex]10\pi m^2[/tex]

Step-by-step explanation:

The volume of a cylinder is calculated using the formula:

[tex]Volume=\pi r^2h[/tex]

The volume is given to be:

[tex]V=140\pi m^3[/tex]

The height of the cylinder is h=14 meters.

We substitute these values into the formula to obtain;

[tex]140\pi=\pi r^2\times 14[/tex]

Divide both sides by 14.

[tex]\frac{140\pi}{14}=\pi r^2[/tex]

[tex]10\pi=\pi r^2[/tex]

The area of the base is a circle which is [tex]\pi r^2=10\pi m^2[/tex]

ANSWER

Rewrite and make substitution.

EXPLANATION

Since Harriet calculated 27 divided 4 and had 6.75.

This means that:

[tex] \frac{27}{4} = 6.75[/tex]

Now we want to find

[tex] \frac{270}{4} [/tex]

without divide.

Therefore we need to rewrite the expression so in terms of

[tex] \frac{27}{4} [/tex]

so that we can substitute.

This will give us;

[tex] \frac{270}{4} = \frac{27}{4} \times 10[/tex]

This implies that,

[tex]\frac{270}{4} = 6.75 \times 10[/tex]

[tex]\frac{270}{4} = 67.5[/tex]

8 units

First, find the area of the 4 by 16 rectangle. 4 times 16 is 64, so that is the area.

The area of a square is calculated with A = S^2, where A is the area and S is the side length.

So, set 64 to be the area and solve for S. 64 = S^2

The opposite of squaring something is finding the square root. So, find the square root of both sides.

square root of 64 = S

Now, what is the square root of 64? Well, what number when multiplied by itself equals 64? There are actually two possibilities here: -8 and 8. However, -8 cannot be the answer since distance cannot be negative, so 8 is the length of the side.

Answer:

B. 34

Step-by-step explanation:

Perimeter= 42+42+x+x

First add the 42 together

42+42 =  84

Then subtract the number away because this was added to the total

152 - 84 = 68

68 is not your missing number

Dividing 68 by 2 which gives you 34

So,

Perimeter = 42+42+34+34 = 152

They had 54 twos and 62 threes.

54 + 62 = 116 outcomes of either 2 or 3

The probability is the number of outcomes divided by the total number of rolls.

116 / 360 = 0.32

The answer is A.

Answer:

0.32.

Step-by-step explanation:

Prob(Rolling a 2) = number of 2's rolled / total number of rolls

=  54/360 = 0.15

Similarly Prob(rolling a 3) =  62/360 = 0.17.

So the probability of a 2 or a 3 = 0.15 + 0.17 = 0.32.
