Answer:

Step-by-step explanation:

The solid red line is y = x + 8 and the dashed line is y = -1/2x. Since the solution is shaded on the left side of y = x + 8 we know that the first part is y ≥ x + 8. We use ≥ and not > because the line is solid, meaning that all points on the line are also solutions to the inequality. The solution is shaded on the right side of y = -1/2x so the second part is y > -1/2x. We use > and not ≥ because the line is dashed, meaning that the points on the line are not solutions to the inequality. Therefore, the answer is y ≥ x + 8 and y > -1/2x.

Ram noticed three students used 1 2/10 dm of tape.what was the total used for three students???

OLga [1]

Answer:

18/5

Step-by-step explanation:

From my understanding, this is 1 whole 2 upon 10

Step 1: Convert mixed fraction into fraction

Multiply whole number by denominator: 1 x 10 = 10

Add numerator: 10 + 2 = 12

Write the result as the numerator and use the same denominator.

12/10

Step 2: Find the total tape used

From my understanding, each student used 12/10 of the tap

So 3 students used: 12/10 x 3 = 18/5

Therefore, the total tape used for three students was 18/5.

Which two fractions have a sum of −7/30 ? Drag and drop the appropriate fraction into each box.

Brrunno [24]

Well you will need two number that are divisible by 30 and add up to -7 so they will have to be a negative.

I would try -2 and -5 which are both divisible by 30 and ad up to -7 so...

-2/30 + -5/30 = -7/30

A produce supplier ships boxes of produce to individual customers. The distribution of weights of shipped boxes is approximately

schepotkina [342]

Answer:

$0.67(4)+ 36$

Option D

Step-by-step explanation:

Given that a producer ships boxes of produce to individual customers.(say x)

X is a normal random variable with mean = 36 and std dev =4 lbs

By definition of std normal variate we know that

$\frac{x-36}{4}$ is N(0,1)

75th percentile of std normal distribution is

0.675

Hence corresponding x would be

$36+0.675(4)$

Option D matches with this value

Hence answer is option D

$0.67(4)+ 36$

Answer:

400(π+2) feet square

Step-by-step explanation:

let x be the diagonal of the cage=40√2 at the same time it is the radius of the circle ( the tiger can go in circle)

but since the cage is part of the circle and not full turn πr²/8

area of the circleπr²+ half area square

(π(40√2)²)/8 +40²/2

3200π/8+1600/2

400π+800

400(π+2) feet square
