What is the value of y in the equation 4(5y − 8 − 2) = 185 − 15?

8.5
9.7
10.5
42.5

Answer:

Step-by-step explanation:

To find the area of a quarter circle, find the area of the whole circle by using the formula A = pi * r^2 and then divide by 4. To find the perimeter of the quarter circle, find the circumference of the whole circle, divide by 4, and then add the radius twice.

Answer: [tex]\frac{\pi *r^{2} }{4}[/tex]

Step-by-step explanation:  We know that the formula for the area of a whole circle is πr². A quarter circle is one-fourth of a circle, so if we divide the area of the whole circle into four, we can find the area of the quarter circle: [tex]\frac{\pi *r^{2} }{4}[/tex]

Answer: A

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

For one scientific notation will not work with negative exponents therefore we can eliminate answer choices A and D

Secondly scientific notation usually has a decimal

Answer choice c does not have a decimal point leaving us with answer choice B

Hope this helps! :)

Answer:

The answer is $240

Step-by-step explanation:

You multiply 1.5 times 60 minutes and get 90, you then add 150 and 90 and you get 240.

Answer:

a. 18

b.144

c.108

Step-by-step explanation:

Using the given, Angle R equal 5x-54 and Angle T is 8u.

Also RS is congruent to ST. Since SR is congruent to ST, their opposite angles are also congruent using base angle theorem. So angle R is equal to Angle T. However, STU is a exterior angle so STU isn't congruent to SRT.

However, we can add , interior angle T, and STU to 180 to find x.

Interior angle T=SRT so interior angle t=5x-54.

Set up equation

[tex]5x - 54 + 8x = 180[/tex]

[tex]13x - 54 = 180[/tex]

[tex]13x = 234[/tex]

[tex]x = 18[/tex]

b.Plug 18 into 8x

[tex]8(18) = 144[/tex]

STU=144

c. Using the triangle exterior angle theorem, the exterior angle is equal to the measure of the sum of two non adjacent angles.

Angle S and Angle R are the non adjacent angle to STU.

So we cast up this equation.

[tex]5x - 54 + s = 180[/tex]

plug 18 in for x

[tex]5(18) - 54 + s = 144[/tex]

[tex]90 - 54 + s = 144[/tex]

[tex]36 + s = 144[/tex]

s=108

Answer:

21.42ft

Step-by-step explanation:

a²+b²=c² where "c" is the hypotenuse of a right triangle and "a" and "b" are the two other sides

now let's plug in the values

21²+b²=30²

b²= 30² - 21²

b²= 459

b= 21.42

Answer:

Quadratic formula

Step-by-step explanation:

You can use the quadratic formula to find solutions for quadratic equations.

Answer:

t=7

Step-by-step explanation:

N=45

find t

45=t^2-t/2

0=t^2-t/2-45

use the quadratic formula

t=6.96~=7

Answer:

Step-by-step explanation:

45 = t2 - t/2

45 = 30(2) - 30/2

45 = 60 - 15

45=45

Answer:

-20x+15

Step-by-step explanation:

You use foil method so you distribute it and it becomes -5*4x amd -5*-3 so it would be -20x+15

-5 x 4x=-20x and -5x x -3 = +15

-20x+15 is the answer

Step-by-step explanation:

To find the total surface area of a prism, you need to calculate the area of two polygonal bases, i.e., the top face and bottom face. And then calculate the area of lateral faces connecting the bases. Add up the area of the two bases and the area of the lateral faces to get the total surface area of a prism.

Hope this helps!

All the love, Ya boi Fraser :)

Answer:

By drawing a net, you can see each face of the prism. You can find the areas of each face and then add them together to find the total surface area.

Answer:

12 cubes

Step-by-step explanation:

If the total volume of the box is 24 cm³ and the volume of each cube is 1 cm³ then that means that 24 total cubes can fit perfectly inside the box. Since there can only be two layers of cubes then we simply need to divide the total amount of cubes that will fit in the box by 2 to find the number of cubes in each layer...

24 / 2 = 12 cubes

Finally, we can see that each layer within the box will contain 12 cubes

Answer:

y = 5 ; x = 4

Step-by-step explanation:

Given :

5x + 6y = 50 - - - (1)

x - 6y = -26 - - - (2)

From (2)

x = - 26 + 6y

Put - 26 + 6y for x in (1)

5(-26 + 6y) + 6y = 50

-130 + 30y + 6y = 50

-130 + 36y = 50

-130 - 50 = - 36y

-180 = - 36y

y = 180 / 36

y = 5

Put y =5 in x = - 26 + 6y

x = - 26 + 6(5)

x = - 26 + 30

x = 4

y = 5 ; x = 4
