a. 22. 79 - amount

b. 129   -   amount

c. 358. 3  - base

d. 40. 65%  - percent

e. 2. 58% - percent

<h3>How to determine the values</h3>

It is important to note that a percentage is the number or ratio expressed as a fraction of 100.

It is denoted using the percent sign, "%"

a. What number is 53% of 43

= 53/ 100 × 43

= 0. 53 × 43

= 22. 79

b. 43% of 300

= 43/ 100 × 300

= 129

c. 12% of what number is 43

12/ 100 × x = 43

x = 43 × 100/ 12

x = 358. 3

d. 43 is what percent of 106

43/106 × 100/ 1

4300×/ 106

40. 5%

e. What percent of 43 is 6

43/ 100 × 6

2.58%

Thus, the percentage of a value is that value divided by 100

Hannah has $500. She buys a camera for $435 and 4 other items for $9 each. Now Hannah wants to buy speakers for $50. Does she ha
Mariana [72]

Answer:

she does not have enough money to buy the speaker

Step-by-step explanation:

Hannah has $500. She buys a camera for $435 and 4 other items for $9 each. Now Hannah wants to buy speakers for $50.

camera for $435

4 items $9 each , 4 times 9 = 36

then buys speaker for $50

435 +36+50=521

Hennah has only $500

but she needs 521 to buy all these things

So she does not have enough money to buy the speaker

PLEASE HELP SOON<br> Find the length of x.
DochEvi [55]
<h2>Hello!</h2>

The answer is:

The length of "x" is equal to 4 units.

<h2>Why?</h2>

To solve the problem and find the length of x, we need to remember the alternate angles rule. The alternate angles rule establish that alternate angles will be also equal.

So, for the triangles, we have:

The angle((α)) formed between the base (2.5) and the hypotenuse (5)  of the big triangle is equal to the angle(α) formed between the base (2) and the hypotenuse (x) of the small triangle. It also means that the triangles are similar since they have congruent angles(α) and proportional sides (SAS).

We are given:

First triangle,

AdjacentSide=2.5\\Hypotenuse=5\\

Second triangle,

AdjacentSide=2\\Hypotenuse=x\\

So, using the cosine identity, we have:

Cos(\alpha)=\frac{AdjacentSide}{Hypotenuse}

Cos(\alpha)=\frac{2.5}{5}=\frac{2}{x}

Cos(\alpha)=\frac{2.5}{5}=\frac{2}{x}\\\\\frac{2.5}{5}=\frac{2}{x}\\\\x=2*\frac{5}{2.5}=4

Therefore, we have that the hypotenuse of the second triangle (x) is equal to 4 units.

Hence, the length of "x" is equal to 4 units.

Have a nice day!
