Answer: 75 goes in the first slot , 93 in the slot next to 75 and 52 goes in the total

Step-by-step explanation:

you put 75 in the first slit because 75 kids has a license and also a job. its like a multiplication table . in the first slot you can see the row of down and over , 75 is next to does have job and above it is does have license then you just do it for the rest if the answers 93 have a job but no license. therefore you just find the box that says no license and does have a job

The ratio of the perimeters of two similar triangles is 4:7. The sides of the larger triangles are 10, 12, and 13cm,
rjkz [21]

Answer:

Perimeter = 20cm

The perimeter is 35 for the larger triangle = 7:4 ratio

the perimeter for the smaller triangle = 4:7 ratio

We add up 4+7 = 11 and multiply 35 x 2 = 70.

so that the smaller triangle = 40  = 40:70

35 = 7 and 20 = 4

To find measurements of 20

we have any number over 10 combined will make the smaller sides possible,

Where hypotenuse would be under 10.

H = 6.5 Sides = 6 + 5 does not add up to 20

H = 9 Sides = 7 + 4  does have near equal spaced symmetry.

H = 9  Sides = 5 + 6  is wrong as no symmetry in measure

H = 8  Sides = 7 + 5 is wrong as no symmetry in measure

H = 7 Sides = 6 + 7  is wrong as equal sides

H = 6 sides = 6.5 + 6.5 is wrong as equal sides

H = 11 Sides = 6 + 3 is wrong has no symmetry.

The measurements must be 9cm, 7cm and 4 cm for the smaller triangle

The perimeter adds up to 20cm.

John took all his money from his savings account. He spent ​$110 on a radio and 4/11 of what was left on presents for his friend
svp [43]

Answer:

$1210

Step-by-step explanation:

Let x be total amount

First John spent $110 on a radio and 4/11 of what was left on presents for his friends so he was left with

\frac{7}{11}(x-110)=\frac{7}{11}x-70

Then he put 2/5 of his remaining money into a checking account

\frac{3}{5}\left(\frac{7}{11}x-70\right)

Rest he donated to charity

420=\frac{3}{5}\left(\frac{7}{11}x-70\right)\\\Rightarrow \left(\frac{7}{11}x-70\right)=\frac{2100}{3}\\\Rightarrow \frac{7}{11}x-70=700\\\Rightarrow \frac{7}{11}x=770\\\Rightarrow x=1210

Hence total amount of money John originally had was $1210

Please help. I think its B since the y-intercept is -1 and it rises up 3 and goes over 1 so that means it is just 3.
borishaifa [10]
You are correct about the y-intercept. In case you are unsure about the slope, you can check using y1 - y2 / x1 - x2:

(0, -1) and (1, 2)

-1 - 2 / 0 - 1
-3 / -1
3

The slope is 3; you chose the correct answer, great job.
