Step-by-step explanation:

To find the third side (let's call it x) you plug the side lengths given into the Pythagorean theorem to get:

5² + 2² = x²

Which, simplified, is:

25 + 4 = x²

And to get x, you do:

x=√(29)

So, if you want it to the nearest hundredth, it is 5.39.

A builder is buying boxes of nails. She has $187 to spend and each box of nails costs $4.

Answers

She can buy 46 boxes

Answer:

46 boxes of nails

Step-by-step explanation:

She has $187 to spend, the maximum.

187/4 = 46.75

Since she cannot buy 0.75 of a box of nails, she can only buy 46. So she is left with an extra $3 and buys 46 boxes of nails.

Sandra and Peter together weigh 275 pounds. Sandra and
Martin together weigh 245 pounds. All three together
weigh 410 pounds. What is Sandra's weight alone?

Answers

Answer:

110 pounds

Step-by-step explanation:

Let the weight of Sandra, Peter and Martin be S, P and M pounds respectively.

S +P= 275 -----(1)

S +M= 245 -----(2)

S +P +M= 410 -----(3)

(3) -(1):

S +P +M -(S +P)= 410 -275

S +P +M -S -P= 135

M= 135

Substitute M= 135 into (2):

S +135= 245

S= 245 -135

S= 110

Thus, Sarah weighs 110 pounds.

Find the perimeter of an isosceles triangle. The base is 3y and each side is (0.6y-7).

Answers

Answer:

Perimeter = 4.2y - 14

Step-by-step explanation:

Perimeter of a triangle = the sum of the three sided of the triangle.

In an isosceles triangle, there are two equal sides and a base.

Perimeter = (0.6y - 7) + (0.6y - 7) + 3y

Perimeter = (0.6y + 0.6y + 3y) - 7 - 7

Perimeter = 1.2y + 3y - 14

Perimeter = 4.2y - 14

b) 4m - 6 = 2
pls I need help

Answers

Answer:

A) a = 4

B) m = 2

Step-by-step explanation:

A) 2a + 7 = 15

2a + 7 - 7 = 15 - 7

2a = 8

2a/2 = 8/2

a = 4

B) 4m - 6 = 2

4m - 6 + 6 = 2 + 6

4m = 8

4m/4 = 8/4

m = 2

Answer:

a = 4 and m = 2.

a) Find the value of a if the total of a being doubled and added to 7 is 15.

b) Find the value of m if the total of m being multiplied by 4 and being subtracted by 6 is 2.

Step-by-step explanation:

2a + 7 = 15

→ Minus 7 from both sides

2a = 8

→ Divide both sides by 2

a = 4

4m - 6 = 2

→ Add 6 to both sides

4m = 8

→ Divide both sides by 2

m = 2                

Can you help me I have a basketball game Tuesday and if I don’t pass I can’t play plz !!

Answers

Answer:  109

========================================================

Explanation:

Angles A and B are supplementary which mean they combine to form a straight line. This further means the angles add to 180.

A+B = 180

(8x-27) + (4x+3) = 180

(8x+4x) + (-27+3) = 180

12x-24 = 180

12x = 180+24

12x = 204

x = 204/12

x = 17

Use this x value to find angles A and B

A = 8x-27 = 8*17-27 = 109B = 4x+3 = 4*17+3 = 71

Note how A+B = 109+71 = 180 to help verify the answer.

Answer:

109

Step-by-step explanation:

supplementary angles equals 180 degrees

8x-27+4x+3=180

12x-24=180

12x=204

x=17

Then you put the 17 where the x is

8(17)-27=109

Find (fog)(x) (gof)(x), if f(x) = 1 - 5x; g (x) = |2x + 3| x​

Answers

Step-by-step explanation:

f (x) = 1 - 5x

g (x) = 2x + 3

find (fog) (x)

it's a composite function so basically we substitute x = 2x + 3 where we see x in f (x) = 1 - 5x

so doing that we'll get

1 - 5(2x + 3)

next expand your brackets

1 - 10x + 15

equate to 0 to make things easier

1 - 10x + 15 = 0

make x the subject

1 + 15 = 10x (this is the same as 10x = 1 + 15)

x = 16/10 (you can leave it as a fraction)

fog(x) = 16/10

find gof (x)

we'll do the same thing again

2(1-5x) + 3

2 -10x + 3 = 0

2 + 3 = 10x

10x = 5

x = 5/10 (reduce)

x = 1/2

gof (x) = 1/2
