Answer:

18.4%

Step-by-step explanation:

The formula for rel. freq. is:

Relative Frequency = Class Frequency/n

Where

Class Frequency will be the number of students in the class we are interested in (in 35-38, the number of students is 9)

n is the total number of students [which is 6+7+8+9+10+9= 49]

Putting into formula we get:

Relative Frequency = 9/49 = 0.1837

To get percentage, we need to multiply by 100:

0.1837 * 100 = 18.37%

Rounded to 1 decimal place, that is 18.4%

A farmer grows corn, tomatoes, and sunflowers on a 320-acre farm. This year, the farmer wants to plant twice as many acres of to

svet-max [94.6K]

Set it up with variables; tomatoes=t, sunflowers=s, corn=c

320=t+s+c

This year;
t=2s
c=t+40

so, replace 2s for t; c=2s+40

now we can put those factors in for 320=t+c+s

320= 2s+2s+40+s
(SIMPLIFY)---> 320=5s+40----> 5s+280----> s=56

now incorporate the s value into the other equations.

c=2s+40----> c=56(2)=40 ----> c=152
t=2s -----> t=2(56) ----> t=112

TOMATOES= 112 acres
CORN= 152 acres
SUNFLOWERS= 56 acres

To check your work: 320=t+s+c ----> 320=112+156+56

I need help with these.

Answer:

See below.

Step-by-step explanation:

5^2 + 12^2 = x^2

25 + 144 = x^2

169 = x^2

x = 13

3^2 + x^2 = [sqrt(10)]^2

9 + x^2 = 10

x^2 = 1

x = 1

1^2 + x^2 = 4^2

1 + x^2 = 16

x^2 = 15

x = sqrt(15)

[sqrt(27)]^2 + x^2 = 6^2

27 + x^2 = 36

x^2 = 9

x = 3

15/5 = c/sqrt(29)

5c = 15 * sqrt(29)

c = 3sqrt(29)

26/13 = x/12

2 = x/12

x = 24

A number n is 150% of number m. is n greater than less than or equal to m

kolbaska11 [484]

100% of anything is the whole thing.

101% of it is more than the whole thing.

150% of it is the whole thing plus half of another one.
