Area=\frac{(a + b)}{2} \cdot h\\144 = \frac{(12 + 8)}{2} \cdot h\\144 = \frac{20}{2} \cdot h\\144 = 10h\\h = \frac{144}{10} = \frac{72}{5}

Solution


h=14.4m

Using the formula

A= 12 meter
B= 8 meter
H = 14.4 m

Trapezoid
Solve for height
h=14.4m


Unit Conversion:
a=12m
b=8m
A=144m²

Using the formula
A=a+b/2h

Solving for H =

The irrational number square root 67 is greater than [blank]
Tanya [424]

Answer:

The irrational number square root 67 is greater than whole number 8

Step-by-step explanation:

Given

\sqrt{67

Required

Complete the sentence

No options are given.

So, we will solve the expression then compare it with the nearest smallest integer

First, we solve the given expression

\sqrt{67

\sqrt{67} \approx 8.185

By comparison:

8.185 > 8

<em>This implies that, the blank will be completed with 8</em>

Brenda says a good estimate for 50× 31 3/4 is 800. is this correct? Explain.
QveST [7]
At first glance, it seems like a good estimate; big numbers make bigger number.
But, this is multiplication, which means big numbers will make an extraordinarily big number, in proportion to the numbers themselves.
If you round 31 3/4 up to 32, you can multiply that by 50. To make the estimate easier, multiply 50 by 2,
50 x 2 = 100
Take the zeros off 50 and 30 to make this a bit simpler, and multiply 5 by 3,
5 x 3 = 15
Add each of the zeros you took off to the 15 to make 1500 (1 zero was taken off 50, and 1 off of 30),
And then add 1500 to that other 100
1500 + 100 = 1600
A good estimate for 50 x 31 3/4 would be 1600, not 800.
Therefore,
No. Brenda's estimate of 800 is NOT a good estimate.

100 POINTS HELP! THIS IS A PROJECT. NOT IN A RUSH.
Helga [31]

Answer

Hello class!

Step-by-step explanation:

1. The mean is the average of a data set.

2. The mode is the most common number in a data set.

3. The median is the middle of the set of numbers.

Of the three, the mean is the only one that requires a formula. I like to think of it in the other dictionary sense of the word (as in, it’s mean as opposed to nice!). That’s because, compared to the other two, it’s not as easy to work with.
