Step-by-step explanation:

Answer:

graph a and table a=B

Step-by-step explanation:

This is because for table a, if you subsite the numbers of x it would give you the answer for y such as y=2x, and since x is 2 y is 4, which is shown on the graph. And since it does not have any add ons, if you make x 0 it would be 0 so it would also be proportional through the orgin. so graph A is also correct.

Answer:  5: 7

Step-by-step explanation:

The total number for teacups: 2 yellow teacups + 5 brown teacups = 7 teacups

the ratio compares the number of brown teacups to the total number of teacups is :

5: 7

The ratio that compares the number of brown teacups to the total number of teacups is 5: 7

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We are given that Mei has 2 yellow teacups and 5 brown teacups.

The total number for teacups is;

2 yellow teacups + 5 brown teacups = 7 teacups

Therefore, the ratio compares the number of brown teacups to the total number of teacups can be;

5: 7

Answer:

15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.

Step-by-step explanation:

Dado que en una encuesta a 200 niños sobre el programa de TV que más les gusta ver se encontró que 30 niños ven dibujos animados, 45 niños miran películas animadas, 55 niños miran programas sobre animales, 38 niños miran programas sobre animales y dibujos animados y 32 niños miran los tres tipos de programas, para determinar el porcentaje de cada grupo​ se deben realizar los siguientes cálculos:

30/200 = 15/100 = 15%

45/200 = 22.5/100 = 22.5%

55/200 = 27.5/100 = 27.5%

38/200 = 19/100 = 19%

32/200 = 16/100 = 16%

Así, 15% de los niños solo ven dibujos animados, 22.5% solo ven películas animadas, 27.5% ven programas sobre animales, 19% miran programas sobre animales y dibujos animados, y 16% ve los tres tipos de programas.

Answer:

The answer is 4

Step-by-step explanation:

You just divide 80 by 15.

She can jump rope 20 times in 15 seconds

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operations is called the arithmetic operator.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

Given that Jen can jump rope 80 times in 60 seconds.

We have to determine the number of jumps can she make in 15 seconds.

Let the number of jumps would be x she can make in 15 seconds

Since she jumps at a constant ratio of seconds to jumps

So according to proportionality,

⇒ 80/60 = x/15

⇒ x = 15(80/60)

⇒ x = 20

Hence, she can jump rope 20 times in 15 seconds.

Answer:

Step-by-step explanation:

5i² + 12i - 32i  = 5i² - 20i

                      = 5i² - (5*4*i)

                      = 5i(i - 4)

Answer:

a = 5 c =11

Step-by-step explanation:

Answer:

sqrt[(80^2) + (20^2)] = (bottom base of the entire rectangle)

= 20(sqrt(17)) units or about 82.46211 units

find angle at bottom corner

arctan(20/80) = about 14.04624 degrees

cos(14.04624) = 20(sqrt17) / (80+a)

solve for a: --> a = 5 units

use pythag for side c

(20^2) + (5^2) = c^2

c is about 20.6155 units or 5(sqrt17)
