Answer:

5120 cm^2

Step-by-step explanation:

Base area = (18 x 40)/2 = 360 cm^2

Base perimeter = 18 + 41 + 41 = 100 cm

LA =  100 x 44 = 4400 cm^2

surface area = 360 x 2 + 4400 = 5120 cm^2

Answer:

The sum of all the data values divided by the number of data values is 7.

Explaination:

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

Answer:

The last one

Step-by-step explanation:

We know that the mean is 7, what we are trying to identify is which situation correctly describes how to find the mean.

Define

Mean = Sum of values divided by number of data values

Reasoning

For "The middle value of the ordered data set is 7."

The middle value is known as the median not mean therefore this answer is not correct.

For "The value that occurs most often in the set is 7."

The number that occurs the most is known as the mode not the mean therefore this is not the correct answer

For " The difference between the smallest value and the largest value is 7.

"

The difference between the smallest and largest number is known as the range therefore this answer is not correct.

We're left with "The sum of all the data values divided by the number of data values is 7." which does indeed correctly describe how to find the mean.

Answer:

Ray

Step-by-step explanation:

A ray is a line that has one definite start point and then continues in one direction forever. Rays are commonly combined to create angles. In an angle, each ray begins at the vertex, the definite starting point, and then goes straight in one direction. In this question, the image would be called ray LM.

Answer:

n = -3

Step-by-step explanation:

We have the equation –2(n + 2) + 6 = 8. First, we simplify it:

–2(n + 2) + 6 = 8

–2(n + 2) = -2n + (-4) = -2n - 4

So now we have:

-2n - 4 + 6 = 8

We can subtract 6 from both sides of the equation to get:

-2n - 4 = 2

We can also add 4 to both sides to get:

-2n = 6

Divide both sides by 2 to get:

-n = 3

Multiply both sides by -1 to get:

n = -3

[tex]4 \frac{1}{4} = 4.25 \: hours[/tex]

Answer:

a quarter of an hour =15 mins

so therefore, 4 quarter hours =

15 x 4= 60 mins

    =1 hour

Answer:

perimeter= p1+p2 +p3+p4=add all sides.

area =l×b=

(10m×14m)= 140m

Answer:

Perimeter = 33.4248cm

Area = 29.42478cm²

Step-by-step explanation:

Perimeter = half circle + rectangle length + radius + 90degree section + rectangle length + radius

radius of the circles = (14 - 10)/2 = 2

Perimeter = 2π + 10 + 2 + π + 10 + 2

Perimeter = 3π + 24 = 33.4248cm

Area = half circle + rectangle + quarter circle

Area = π(2)²/2 + 10×2 + π(2)²/4

Area = 29.42478cm²

Answer:

a ≥ 18

Explanation:

This inequality represents that your age must be 18 OR GREATER in order to vote.

Answer:

x= 29 degrees,  y= 61 degrees

Step-by-step explanation:

Complementary angles and up to 90 degrees, . Sif half of 90 is 45 and y is 16 more than x,  you just need to add 16 to y and subtract 16 from x.

Answer:

1.6<x<9.6

Step-by-step explanation:

If I remember correctly, any two side lengths must add up to be larger than the other.  So the smallest the side length can be would be found from x+4.0>5.6  So x > 1.6.

The largest it can be would be found from 4.0+5.6>x  So x < 9.6

Answer:  Median = 50

Step by Step Explanation:

1. Sort the values from smallest to largest (Ascending order) - This step is already done for you in this data set.

2. Find the middle most number. If you're left with two numbers in the middle, find the average of those two numbers - Since this data set is pretty small, you can probably notice that the middle most number is 50.

I hope this helps! :D

Answer:

-6.8

Step-by-step explanation:

its kinda hard to explain this problem

Answer: -6.8

Step-by-step explanation:

the farther you go down, the less it is (because they're negative numbers) so you just keep counting line after line increasing by a tenth on each line and you eventually end up with -6.8!

Hope this helps! Good luck with your future work! <3

Answer:

7

Step-by-step explanation:

2^3 • 2^7 = 2^10

When multiplying exponents, the exponents add up together. In other words, just subtract 10-3 = 7 that would be your missing exponent!

Hope this helps, good luck!
