A math book consists of two sections: arithmetic and geometry in the ratio 5:3. How much of each type of content will be needed

Sergeeva-Olga [200]

Answer:

As the ratio is 5:3, it totals 8 parts. I would do 480 divided by 8 to get the number of pages per part, then multiply that number into the ratio.

480 / 8 = 60

The value of each part being 60 put into the ratio 5:3 = 60x5 : 60x3

Which gives your answer.

Direct variations need help

Solnce55 [7]

Answer:

Part 11) The table represent a direct variation. The equation is $y=18x$

Part 12) The table represent a direct variation. The equation is $y=0.4x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Part 11)

For x=0.5, y=9

Find the value of k

$k=y/x$ -----> $k=9/0.5=18$

For x=3, y=54

Find the value of k

$k=y/x$ -----> $k=54/3=18$

For x=-2, y=-36

Find the value of k

$k=y/x$ -----> $k=-36/-2=18$

For x=1, y=18

Find the value of k

$k=y/x$ -----> $k=18/1=18$

For x=-8, y=-144

Find the value of k

$k=y/x$ -----> $k=-144/-8=18$

The values of k is the same for each ordered pair

therefore

The table represent a direct variation

The linear equation is

$y=18x$

Part 12)

For x=-5, y=-2

Find the value of k

$k=y/x$ -----> $k=-2/-5=2/5=0.40$

For x=3, y=1.2

Find the value of k

$k=y/x$ -----> $k=1.2/3=0.40$

For x=-2, y=-0.8

Find the value of k

$k=y/x$ -----> $k=-0.8/-2=0.4$

For x=10, y=4

Find the value of k

$k=y/x$ -----> $k=4/10=0.4$

For x=20, y=8

Find the value of k

$k=y/x$ -----> $k=8/20=0.4$

The values of k is the same for each ordered pair

therefore

The table represent a direct variation

The linear equation is

$y=0.4x$

In a triangle the first angle is greater than the second angle by 18 degree and less than the third angle by 10 grade. Express a

serg [7]

Answer:

The 3 angles are 62 2/3, 44 2/.3 and 72 2/3 degrees.

Step-by-step explanation:

let x be the first angle then the the second angle is x - 18 and the third angle = x + 10

The 3 angles add up to 180 so:

x + x - 18 + x + 10 = 180

3x = 180 + 18 - 10 = 188

x = 188/3 = 62 2/3 degrees.

x - 18 = 44 2/3

x + 10 = 72 2/3.
