How much is 1% out of $10

2 answers:

6 0

To find a percent of a whole number, you first need to convert the percent to a decimal.

1% as a decimal is 0.01.

Then, you multiply this decimal by the whole number to get your final answer.

0.01*10=0.1

Your final answer is $0.10, or 10⊄

Your answer is 10¢ because you multiply the decimal by its number

Answer:

157 inches squared

Step-by-step explanation:

Divide the figure into smaller figures (see image for one way):

Then, find the area of each figure. In my example:

= (4x5)+(5x12)+(11x7)

= 20+60+77

= 80+77

= 157 inches squared

Answer:

a) AC = $\sqrt{13}$

b) Area = $\frac{\sqrt 3}{4}$ × $a^{2}$

Step-by-step explanation:

a) From question,

AC = BC, CD⊥AB

Now in ΔCAD and ΔCBD

AC=BC, ∠A = ∠B and AD=BD (because in isosceles triangle perpendicular bisects the side).

then, from SAS potulates

ΔCAD≅ΔCBD

So,

AD = $\frac{AB}{2}$ = $\frac{4}{2}$ = 2 in

From Pythagorean theorem in ΔADC

$AC^{2}$ = $AD^{2}$ + $CD^{2}$

$AC^{2}$ = $2^{2}$ + $3^{2}$

$AC^{2}$ = 4 + 9 = 13

AC = $\sqrt{13}$

b) In given ΔABC,

AB = BC = AC = a, means ΔABC is a equilateral triangle.

So, area of equilateral triangle is

Area = $\frac{\sqrt 3}{4}$ × $side^{2}$

side = a

then,

Area = $\frac{\sqrt 3}{4}$ × $a^{2}$
