What is the length of HG?

Mathematics
1 answer:
Leviafan [203]3 years ago
6 0

Answer:

HG = 5

Step-by-step explanation:

Given

HE = 8mm

EF = 12mm

Area = 68mm^2

Find the length of HG

First, it should be noted that the displayed figure is a trapezium

<em>The area of a trapezium is calculated by multiplying the sum of parallel sides by half its height;</em>

In this case;

Area = \frac{HG + EF}{2} * HE

Substitute the values of Area, HE and EF

68 = \frac{HG + 12}{2} * 8

68 = (HG + 12) * 4

Divide both sides by 4

\frac{68}{4} = \frac{(HG + 12) * 4}{4}

17 = HG + 12

Subtract 12 from both sides

17 - 12 = HG + 12 - 12

5 = HG

HG = 5

<em>Hence, the length of HG is 5mm</em>

Y = (x) =(1/8)^x<br> Find f(x) when X =<br> (1/3)<br> Round your answer to the nearest thousandth.
vlada-n [284]

Answer:

1/2.

Step-by-step explanation:

f(x) = (1/8)^x

when x = 1/3

f(x)  =  (1/8)^1/3

f(x) = ∛(1/8)

f(x) = 1 / ∛8

f(x) = 1/2.

A community swimming pool is a rectangular prism that is 30 feet long, 12 feet wide, and 5 feet deep. The wading pool is half as
topjm [15]

Answer:

The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.

Step-by-step explanation:

By definition of rectangular prism, we get the respective formulas for the volumes of the community swimming pool and the wadling pool, respectively:

Community swimming pool

V_{c} = l\cdot w\cdot h (1)

Wading pool

V_{w} = \left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w (2)

Where:

l – Length of the swimming pool, measured in feet.

h – Depth of the swimming pool, measured in feet.

w – Width of the swimming pool, measured in feet.

V_{c} – Volume of the community swimming pool, measured in cubic feet.

V_{w} – Volume of the wading swimming pool, measured in cubic feet.

The ratio of the volume of the community swimming pool to the volume of the wadling pool is:

\frac{V_{c}}{V_{w}} = \frac{l\cdot w \cdot h}{\left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w} (3)

\frac{V_{c}}{V_{w}} = \frac{1}{\frac{1}{4} }

\frac{V_{c}}{V_{w}} = 4

The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.

For a population with u=100 and a=20, what is the z-score that corresponds to x=90?
max2010maxim [7]
I guess that u = μ & that a=σ. If so:

μ =100 & that σ =20 & x=20

Z score = (x-μ) / σ  ==> Z score = (90-100)/20 ==> Z = - 0.5
