karl scored 14 out of 20 in a test work out his score as a percentage

Answer: i think the answer is 320

Step-by-step explanation:

i say 320 because a square has 4 sides and there is 80 yards so all i did is multiply 80 x 4 = 320

Answer:

Step-by-step explanation:

[tex]d^2=x^2+x^2\\ \\ 2x^2=80^2\\ \\ 2x^2=6400\\ \\ x^2=3200\\ x=\sqrt{3200}\\ \\ P=4x\\ \\ P=4\sqrt{3200}yds\\ \\ P\approx 226.27yds[/tex]

Answer:

Step-by-step explanation:

you only need the rate of change and the y intercept.

Answer: D. 5 units

Step-by-step explanation:

[tex]d=\sqrt{(x_{2} -x_{1} )^{2} +(y_{2} -y_{1} )^{2} } \\\\PQ=\sqrt{(3-(-1) )^{2} +(-1-(-4) )^{2} } \\\\PQ=\sqrt{4^{2}+3^{2} } \\\\PQ=\sqrt{16+9} \\\\PQ=\sqrt{25} =5[/tex]

Answer:

[tex]y=2\frac{1}{6}[/tex] or [tex]\frac{13}{6}[/tex]

Step-by-step explanation:

We know that [tex]x[/tex] and [tex]y[/tex] are directly proportional. Therefore, using the given information, we can set up the following proportion:

[tex]\frac{6.5}{12}=\frac{y}{4}[/tex]

Solving for [tex]y[/tex], we get:

[tex]\frac{6.5}{12}=\frac{y}{4}[/tex]

[tex]12*y=6.5*4[/tex] (Cross-Products Property)

[tex]12y=26[/tex] (Simplify)

[tex]\frac{12y}{12} =\frac{26}{12}[/tex] (Divide both sides of the equation by [tex]12[/tex] to get rid of [tex]y[/tex]'s coefficient)

[tex]y=2\frac{1}{6}[/tex] or [tex]\frac{13}{6}[/tex] (Simplify)

Answer:

c) 126 inches of the answer

Answer:

C. 126 inches²

Step-by-step explanation:

To find the area of a trapezoid multiply the sum of the two bases (12 + 16) and the height divide by 2 (9 / 2) by each other

(12 + 16)9/2

Add 12 and 16 to get 28.

28(9/2)

Multiply 28 by 9 to get 252.

252/2

Divide 252 by 2 to get 126.

The area of the trapezoid is 126 inches².

Answer:

slope (m) = 4

y-intercept (b) = -2

Step-by-step explanation:

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

Explanation:

Let's compute the slope of the line through the two original points

m = (y2-y1)/(x2-x1)

m = (4-10)/(7-(-2))

m = (4-10)/(7+2)

m = -6/9

m = (-2*3)/(3*3)

m = -2/3

The slope is -2/3

-------------

Now apply the scale factor.

We'll multiply each coordinate of each point by 2

(-2,10) becomes (-4,20) after multiplying each coordinate by 2

(7,4) becomes (14,8) after multiplying each coordinate by 2

Let's find the slope of the line through (-4,20) and (14,8)

m = (y2-y1)/(x2-x1)

m = (8-20)/(14-(-4))

m = (8-20)/(14+4)

m = -12/18

m = (-2*6)/(3*6)

m = -2/3

We get the same slope. This isn't a coincidence. Dilating a set of points will preserve the slope of the line through those points.

If A and B are the two original points, and A' and B' are the dilated counterparts, then the slope of line AB is the same as the slope of line A'B'.

The scale factor doesn't affect the answer.

Answer:

4x + 3 = 11

4x = 11 - 3

4x = 8

x = 8 ÷ 4

x = 2

3x - 5 = 7

3x = 7 + 5

3x = 12

x = 12 ÷ 3

x = 4

8x - 5 = -37

8x = -37 + 5

8x = -32

x = -32 ÷ 8

x = -4

7(x - 3) = 21

7x - 21 = 21

7x = 21 + 21

7x = 42

x = 42 ÷ 7

x = 6

They subtracted 5 on both sides of the equation. They were suppose to add 5 on both sides of the equation for it to cancel out each other. If you need any further explanation, please ask me :)

Correct version:

5y + (-5) = 10

       +5     +5    add 5 to both sides, 5's will cancel out on left side.

___________

5y     15

__ = __        divide 5 on both sides, 5's will cancel out on left side.

5      5

y = 3, final answer

Answer:

its the first part the (-5) -5  is supposed to be (-5) +5

Step-by-step explanation:

so the equation is 5y=15

then you divide 5y/5 is y so then you 15/5 is 3

so the answer is y=3
