Answer: third graph -4,2 -2,-7

Step-by-step explanation:

Answer:

Jim + June + Alex = 82 (x+9) x + (x-8) = 82 3x +1 = 82 3x = 82 - 1 = 81 x = 81/3 = 27. ANSWER. June is 27 years old; Jim is 27+9 = 36 years old; Alex is 27-8 = 19 years old.

Answer:

width = 126 ft

Step-by-step explanation:

I'm going to assume that I am solving for width.

Area = width x length

84 = 2/3 x width

Now divide 84 by 2/3 to get the width (when you divide by a fraction, you actually multiply by its reciprocal, so it is 84 times 3/2)

84 x 3/2 = width

width = 126 feet

Answer:

Step-by-step explanation:

The total number of triangles is 5

The total number of all shapes is 13

The ratio is triangles to total

The ratio is 5 to 13

Note

This problem is not very well defined. Notice the circle at the bottom left. It's less than 1/2 a circle. Question: do you count it or don't you. The answer to that question will influence other partial figures.

All you do is count the total number of figures and the number of triangles. I did count the part circle on the lower left as with the triangles that are missing their tops.

Answer:

Heyya little student!

Sin means [tex]\frac{opposite }{hypotenuse}[/tex]

5 is the hypotenuse (its opposite to 90 degrees )

So, sin β would be:-

the side opposite to the angle β divided by the hypotenuse of the triangle.

The side opposite to β is 4

and as I said earlier, the hypotenuse is 5

I hope it helped you!

Answer:

I say 3 sandwiches for 15.

Step-by-step explanation:

to find the best price divided the numbers

15 divided by 3= 5

5 is the price per sandwich for this

21 divided by 4= 5.25

5.25 per sandwich

the 3 for 15 is a better deal. You save money.

Answer:

132,000 millimeters squared, H= 105, R= 20

Step-by-step explanation:

Volume equation (r= radius, h = height)

v= (pie)x r^2 x h

Pie = 22/7

r = 1/2 the diameter, so 40/2= 20. r = 20

h = 105

Substitute

(22/7) x 20^2 x 105

20^2 = 400

(22/7) x 400 x 105 = 132,000

C on edge

Step-by-step explanation:

Answer:

the length is 10

the width is 5

Step-by-step explanation:

Hey there!

To solve this equation we use the formula

50=5/x

step 1 divide each side by 5

50/5=10

so we can conclude that x (or the width) = 5

then we add 5 (because the length is 5 more then the width)

5+5=10

so length =10 and width = 5

Answer:

[tex]E(x) = 99[/tex]

Step-by-step explanation:

Given

The attached table

Required

Number of times 3 or 4 will occur

First, we complete the table as follows:

[tex]P(1) + P(2) +......+P(6) =1[/tex]

[tex]0.13 + 0.05 + P(3) + 0.21 + 0.19 + 0.3 = 1[/tex]

Collect Like Terms

[tex]P(3)= 1 -(0.13 + 0.05 + 0.21 + 0.19 + 0.3 )[/tex]

[tex]P(3)= 0.12[/tex]

The expected number of times is:

[tex]E(x)= n * P(x)[/tex]

So, we have:

[tex]E(x) = 300 * (0.12 + 0.21)[/tex]

[tex]E(x) = 300 * (0.33)[/tex]

[tex]E(x) = 99[/tex]

Answer:  1.95

Step-by-step explanation:

Luis is Harry's height minus 0.25m, which means Harry is Luis' height plus 0.25m.

Luis + 0.25 = Harry

1.7 + 0.25 = 1.95 m

it should look like this

Answer:

44

Step-by-step explanation:

[tex]BC^{2} = (15-12)^{2} + (8-4)^{2}\\BC^{2} =9 + 16\\BC = \sqrt{9+16} \\BC = \sqrt{25} \\BC = 5[/tex]

P  = 12 + 15 + 8 + 4 + 5 = 44

Answer:

97

Step-by-step explanation:

5,7,15,17,25,27,35,37,45,47,55,57,65,67,75,77,85,87,95,97

Answer:

28inches

Step-by-step explanation:

∠A + ∠B + ∠C = 180°

∠A + 65° +93° = 180°

∠A + 158° = 180°

∠A= 180°-158° = 22°

Using Law of Sines

a/sinA= b/sinB

a/sin22= 68 inches/sin65

a/sin22 = 68/0.9063 = 75.03

a = 75.03 x sin 22

a = 75.03 x 0.3746 = 28.106238≈28 inches

Answer: 25 sixth graders

Step-by-step explanation:

Sixth-graders are in a ratio with fifth graders in the band at 5:4 and there are 20 fifth-grade students in the band.

To find the number of 6th graders, use direct proportion and assume the sixth grader number is x:

5                   :            4

x                    :            20

4x = 100

x = 100 / 4

x = 25 sixth graders
