a sandwich shop has 60 stores and 70 percent of the stores are I California. How many stores are in California and Nevada

Aliun [14]

Answer:

The number of stores in California 42

The number of stores in Nevada 18

Step-by-step explanation:

Given as :

The total sandwich shop in California and Nevada = 60

The percentage of shop in California = 70%

So, The percentage of shop in Nevada = 100% - 70% = 30%

Let The number of stores in California = c

And The number of stores in Nevada = n

Now, According to question

The number of stores in California = 70% of the total number of shops

I.e c = $\frac{70}{100}$ × total number of shops

Or, c = $\frac{70}{100}$ × 60

∴ c = $\frac{70\times 60}{100}$

or, c = $\frac{4200}{100}$

or, c = 42

So, The number of stores in California = c =42

Again

The number of stores in Nevada = 30% of the total number of shops

I.e n = $\frac{30}{100}$ × total number of shops

Or, n = $\frac{30}{100}$ × 60

∴ n = $\frac{30\times 60}{100}$

or, n = $\frac{1800}{100}$

or, n = 18

So, The number of stores in Nevada = n = 18

Hence The number of stores in California 42

And The number of stores in Nevada 18 Answer

So, in an easier way to say it
4 × 5 × -2

You would start by doing
4 × 5 = 20
Then,
20 × -2 = 40

So your answer is -40

Hope I helped ♥

Base of triangle exceeds the height by 4. If the area is 178.5 square inches, find the length of the base and the height of the

xxMikexx [17]

Area of a triangle:
A= (1/2)(bh)

In this problem we are given:
A= 178.5 $in^{2}$
b= h+4 in
h= UNKNOWN ("h")

Plug in our values into the area equation and solve for "h":
$A= \frac{1}{2} bh$
$178.5 = \frac{1}{2} ((h+4)h)$ (multiply each side by 2 to get rid of the 1/2)
$357 = ((h+4)h)$
$357 = h^{2} +4h$
$0= h^{2} +4h -357$
(357/21=17)
$0= (h+21)(h-17)$ (solve both inequalities separately)

$0= (h+21)$
$-21= h$ ( a negative height is not possible so, this answer is incorrect.)

$0=(h-17)$
$h=17 in$

Answer: base = (h+4)= (17+ 4) b= 21 in h= 17in
