Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

Form on number to the other there is a difference,and the difference are all odd numbers

From 100 to 93 is 7

From 98 to 84 is 9

From 84 to 73 is 11

From 73 to 45 is 28 this shows that there is a number missing

So from 73 to x should be 13

And from x to 45 should be 15

So 73 -13=60

And 60-15=45

So x is 60

The ratio of students to teachers at a school is 19 to 1 how many students are there in each total number of people

vladimir2022 [97]

Question:

The ratio of students to teachers at a school is 19 : 1. How many students are there in each total number of people?

A: 100 people

b. 280 people

c.440 people

d.760 people

Answer:

A )95 students and 5 teachers

B)266 students and 14 teachers

C)418 students and 22 teachers

D)722 students and 38 teachers

Step-by-step explanation:

A: 100 people

Ratio = 19 : 1

The sum of the ratio is 19 + 1 = 20

Scale factor = $\frac{100}{20}$

scale factor = 5

The number students is $19 \times 5$ = 95

The number of teachers is $1 \times 5$ = 5

b. 280 people

Ratio = 19 : 1

The sum of the ratio is 19 + 1 = 20

Scale factor = $\frac{280}{20}$

scale factor = 14

The number students is $19 \times 14$ = 266

The number of teachers is $1 \times 14$ = 14

c.440 people

Ratio = 19 : 1

The sum of the ratio is 19 + 1 = 20

Scale factor = $\frac{440}{20}$

scale factor = 22

The number students is $19 \times 22$ = 418

The number of teachers is $1 \times 22$ = 22

d.760 people

Ratio = 19 : 1

The sum of the ratio is 19 + 1 = 20

Scale factor = $\frac{760}{20}$

scale factor = 38

The number students is $19 \times 38$ = 722

The number of teachers is $1 \times 38$ = 38

Given the ABC DEF find the value of x and y

Artemon [7]

Answer: x = 7.2, y = 7.5

Step-by-step explanation:

Similar triangles have the same proportions.

Since ABC ≅ DEF, then $\dfrac{AB}{DE}=\dfrac{BC}{EF}=\dfrac{AC}{DF}$

Let's solve for x:

$\dfrac{BC}{EF}=\dfrac{AC}{DF}$

⇒ $\dfrac{5}{4}=\dfrac{9}{x}$

⇒ $5(x)=4(9)$

⇒ $x = \dfrac{4(9)}{5}$

⇒ $x = \dfrac{36}{5}$

⇒ $x = 7.2$

Let's solve for y:

$\dfrac{BC}{EF}=\dfrac{AB}{DE}$

⇒ $\dfrac{5}{4}=\dfrac{y}{6}$

⇒ $5(6)=4(y)$

⇒ $\dfrac{5(6)}{4}=y$

⇒ $\dfrac{30}{4}=y$

⇒ $7.5=y$
