Divide the total weight of dough by the amount required for 1 pizza

20 $\frac{1}{4}$ ÷ 1 $\frac{1}{8}$ ( change mixed numbers to improper fractions )

= $\frac{81}{4}$ ÷ $\frac{9}{8}$

• leave first fraction , change ÷ to × , turn second fraction ' upside down '

= $\frac{81}{4}$ × $\frac{8}{9}$ ( cancel 81 and 9 by 9 )

= $\frac{9}{4}$ × 8 ( cancel 4 and 8 by 4 )

= 9 × 2

= 18 pizza's

A plane has fees for 420 passengers 15% of the seats are empty how many passengers are on the plane

serious [3.7K]

Answer:

357 passengers

Step-by-step explanation:

$\frac{x}{420}=\frac{85}{100}$ (The $\frac{85}{100}$ is 85% of the 100% people because 15% is missing)

When you cross-simplify you get: $\frac{x}{21}=\frac{85}{5}$ which is $\frac{x}{21}=17$

Finally, multiply 17 by 21 to get x.

Therefore, x=357

dalvyx [7]

Answer:

The number of seniors who scored above 96% is 1.

Step-by-step explanation:

Consider the provided information.

Two percent of all seniors in a class of 50 have scored above 96% on an ext exam.

Now we need to find the number of seniors who scored above 96%

For this we need to find the two percent of 50.

2% of 50 can be calculated as:

$\frac{2}{100}\times50$

$\frac{100}{100}$

$1$

Hence, the number of seniors who scored above 96% is 1.

jek_recluse [69]

Answer:

22.97

Step-by-step explanation:

Given that the average cost of an IRS Form 1040 tax filing at Thetis Tax Service is $138.00.

Let x be the average cost an IRS Form 1040 tax filing at Thetis Tax Service

$P(X$ is given

From std normal distribution table we find 77th percentile z value.

z=0.74

Corresponding X value = 155

i.e. $0.74=\frac{155-138}{s}$ where s is the std deviation

Simplify to get

Std deviation = $\frac{17}{0.74} \\=22.97$
