Answers

Answer 1

Answer:

Explanation:

First you convert

into a decimal which is

.80

then you multiply it by

.80

We multiply it by

because that's our total and by

.80

because that's the amount that we got correct. Had it been

100

then that would mean we got every question right.

Step-by-step explanation:

Answer 2

The answer is 16. If the test is 20 questions, each question is 5 points. (100/20)

Answers

Answer:

linear or Quadratic

i hope it works

answer: quadratic

you know it’s a quadratic when the second difference is the same number
so

the first difference is:
0 to -3 is -3
-3 to -4 is -1
-4 to -3 is +1
-3 to 0 is + 3

the second difference is:
-3 to -1 is +2
-1 to 1 is +2
1 to 3 is +2

since the second difference is always +2
the function is QUADRATIC

Hi! need help asap xx

Answers

Answer:

Step-by-step explanation:

The 3 triangles are all similar.

Using the 2 inside then the ratios of corresponding sides are equal, that is

[tex]\frac{x}{3}[/tex] = [tex]\frac{12}{x}[/tex] ( cross- multiply )

x² = 36 ( take the square root of both sides )

x = [tex]\sqrt{36}[/tex] = 6 → C

Answer:

C) x = 6

because this is a right triangle

=> we have:

(12² + x²)(3² + x²) = (15x)²

<=> 1296 + 153x² + x⁴ = 225x²

<=> x⁴ - 72x² + 1296 = 0

<=> (x² - 36)² = 0

<=> x² = 36

=> x = 6

Pls help find x in both

Answers

Answer:

Step-by-step explanation:

In similar triangles, corresponding sides are in same ratio

[tex]\frac{28}{24} = \frac{3x-9}{x +8}\\\\\frac{7}{6}=\frac{3x-9}{x+8}\\[/tex]

Cross multiply,

7*(x + 8) = 6*(3x -9 )

7x + 7*8 = 6*3x - 6*9

7x + 56 = 18x - 54

56 = 18x - 7x -54

56 = 11x - 54

11x - 54 = 56

11x = 56 +54

11x = 110

x = 110 /11

x = 10

PR = 3x -9

solve the equation -30p-2=58 for p.

Answers

Answer:

p=-2

Step-by-step explanation:

1.Combine like terms on both sides.

2.Subtract 6 y 6y 6y on both sides to keep the variable y to the left side only.

3.Add 11 to both sides of the equation.

4.Finally, divide both sides by −10 to get the solution.
