20% of what number is 18 Explain.

2 answers:

8 0

In this question, the thing that needs to be found is the number whose 20% would be 18. The information's required for getting to the solution are already provided in the question. based on those given information's, the answer can be deduced very easily.
Let us assume the unknown number to be = x
Then
(20/100) * x = 18
x/5 = 18
x = 18 * 5
= 90
so the unknown number in the question is 90. I hope the procedure is clear enough for you to understand.

We have a proportion: 18/?= 20/100

Cross multiply:
20*?= 18*100
⇒ ?= 18*100/20= 90

20% of 90 is 18~

Answer:

Step-by-step explanation:

a). Since, ΔABC ~ ΔWYZ

Their corresponding sides will be proportional.

$\frac{AB}{WY}=\frac{BC}{YZ}= \frac{AC}{WZ}$

$\frac{194}{WY}=\frac{BC}{1}= \frac{130}{WZ}$ --------(1)

By applying Pythagoras theorem in ΔABC,

AB² = AC² + BC²

BC² = AB² - AC²

BC² = (194)² - (130)²

BC² = 20736

BC = 144

From equation (1)

$\frac{194}{WY}=\frac{144}{1}= \frac{130}{WZ}$

$\frac{194}{WY}=\frac{144}{1}$

WY = $\frac{194}{144}$

WY = $\frac{97}{72}$ = 1.35

$\frac{144}{1}= \frac{130}{WZ}$

WZ = $\frac{130}{144}$

WZ = $\frac{65}{72}$ = 0.90

b). tan(A) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

= $\frac{144}{130}$

= $\frac{72}{65}$

Since, ΔABC ~ ΔWYZ,

∠A ≅ ∠W

Therefore, tangent of angle A and angle W will measure $\frac{72}{65}$ .

How many minutes are there in 2 3/5 hours

mars1129 [50]

156 minutes.

To find this, remember that an hour has sixty minutes. With this information, it is also given that there are two hours, thus meaning that we have to multiply sixty by two. This will give you 120. Next, you need to figure out the 3/5's portion of an hour. To find 1/5 of an hour, simply divide sixty by five. With that, you get the answer of 12. But because it says 3/5, you need to multiply 12 by 3, giving you 36. Finally, you add 36 to 120 to get the final answer of 156.

Hope this helps!

Felicia has a garden in the shape of a parallelogram as shown. What is the area of her garden? 72 ft² 75 ft² 92 ft² 96 ft² Paral

Serhud [2]

Answer:

72 ft²

Step-by-step explanation:

Given :

Parallelogram ABCD with side AD parallel to side BC and side AB is parallel to side DC.

Point E is on side AB. AE is 3 feet. DC is 9 feet.

A dotted segment DE runs from point D to the opposite side AB and is perpendicular to side AB.

DE is 8 feet.

To Find: Area of parallelogram

Solution :

Refer the attached figure .

Since opposite sides of parallelogram is equal .

So DC=AB=9 feet

Area of parallelogram = base * height

= AB*DE

=9*8 = 72 ft²

Thus the area of garden in the shape of parallelogram is 72 ft²
