what is the answer for this​

Answer:

15

Step-by-step explanation:

18/3=6

15/3=5

Answer:

15

Step-by-step explanation:

If the ratio is 6:5 and we know the boys are 18, we have 18:?

18/6=3, so we have to do 5*3. 5*3=15.

The ratio is 18:15, the number of girls in the classroom is 15

Answer:

A = $13,564.80

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year.

Solving our equation:

A = 12560(1 + (0.02 × 4)) = 13564.8

A = $13,564.80

The total amount accrued, principal plus interest, from simple interest on a principal of $12,560.00 at a rate of 2% per year for 4 years is $13,564.80.

Step-by-step explanation:

Calculate the unit price of a football and a baseball

2 footballs cost $17.00 , then

1 football costs $17 ÷ 2 = $8.50

A baseball is 50% of a football, thus

cost of base ball = 50% of $8.50 = 0.5 × $8.50 = $4.25

(10)

4 footballs cost $34.00 ( given in table )

6 baseballs cost 6 × $4.25 = $25.50 < $34

Thus 6 baseballs < 4 footballs is True

(11)

The difference in price = $8.50 - $4.25 = $4.25

Thus the difference in price is greater than $3, not less False

(12)

3 footballs cost 3 × $8.50 = $25.50

6 baseballs cost 6 × $4.25 = $25.50

Thus the costs are equal is True

(a)

If 2 chords of a circle intersect then the product of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord.

(b)

If 2 secants are drawn from an external point to a circle then the product of the measures of one secant's external part and the entire secant is equal to the product of the measures of the other secant's external part and that entire secant.

(c)

If a tangent and a secant are drawn from an external point to a circle , then the square of the measure of the tangent is equal to the product of the measures of the secant's external part and the entire secant.

Step-by-step explanation:

[tex]We\ observe\ that,\\For\ every\ number\ n\ in\ the\ sequence, the\ number\ next\ to\ it\ is\ 4n.\\Hence,\\In\ order\ to\ continue\ the\ sequence:\\1,4,16,64,256[/tex]

Answer:

1, 4, 16, 64, 256

Step-by-step explanation:

The sequence follows the rule: n * 4

1 * 4 = 4

4 * 4 = 16

16 * 4 = 64

Multiply 64 by 4.

64 * 4 = 256

Answer:

33.51

Step-by-step explanation:

There's a formula using the value of the angle but I don't remember it so the most easy way is:

A circle has an angle of 360°

so our section has an angle of 60

and we know that 360=60*6

so the area of the circle we divide it by 6 and we get the area we want

[tex]A=\pi r^2\\\\A=\pi (8)^2\\\\A=64\pi[/tex]

divide this by 6

[tex]A_1=A/6=64\pi/6\approx 33.51[/tex] units squared

Answer:

720

Step-by-step explanation:

To solve a problem like this, you do: !6

This basically means 6*5*4*3*2*1

6*5 = 30

30*4=120

120*3=360

360*2=720

720*1=720

Answer:

V = 0.8 in^3

Step-by-step explanation:

Formula:

V = πr^2(h/3)

C = 2πr

Given:

h=11.1

C = 17.6

C = 2πr

17.6 = 22πr

0.8/π = r

V = πr^2(h/3)

V = π(0.8/π)^2((11.1)/3)

V = π(0.0648455575)(3.7)

V = 0.8 in^3

Answer:

$450.24

Step-by-step explanation:

According to my quiz...

First, second and fourth options are true about triangle XYZ.

XY measures [tex]\sqrt{26}[/tex] units.

YZ measures [tex]\sqrt{52}[/tex] units.

ZX measures [tex]\sqrt{26}[/tex] units.

XYZ is a right triangle.

A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.

Given X (-1, 5), Y (4, 4), Z (-2, 0)

Distance between two points D = [tex]\sqrt{(x_{2}-x_{1}) ^{2} +(y_{2}-y_{1}) ^{2}}[/tex]

|XY| = [tex]\sqrt{(4-5)^{2} +(4+1)^{2} } =\sqrt{1^{2}+5^{2} } =\sqrt{26}[/tex]

|YZ| = [tex]\sqrt{(0-4)^{2} +(-2-4)^{2} } =\sqrt{4^{2}+6^{2} } =\sqrt{52}[/tex]

|XZ| = [tex]\sqrt{(0-5)^{2} +(-2+1)^{2} } =\sqrt{5^{2}+1^{2} } =\sqrt{26}[/tex]

[tex]|XY|^{2} +|XZ|^{2} =|YZ|^{2}[/tex]

So, XYZ is a right triangle.

So, the first, second and fourth options are correct.
