On a map, 90 miles is represented by 3 inches. A measure of inch on the map would represent miles.

Answers

Complete Question

On a map, 90 miles is represented by 3 inches. A measure of 1/2 inch on the map would represent miles.

Answer:

15 miles

Step-by-step explanation:

From the above question,

3 inches = 90 miles

1/2 inch = x miles

Cross Multiply

3 inches × x miles = 90 miles × 1/2 inch

x miles = 90 miles × 1/2 inch/3 inches

x miles = 15 miles

Therefore, a measure of 1/2 inch on the map would represent 15 miles

Olive has 600 fruit trees. Some of the trees are apple trees. The rest of the trees are pears trees and plum trees in the ratio of 7:5 there are 175 plum trees what is the fraction of apple trees

Answers

Answer: 3/10

Step-by-step explanation:

Since the rest of the trees are pears trees and plum trees in the ratio of 7:5 and there are 175 plum trees, the number of pear trees will be:

= 175 ÷ 5/7

= 175 × 7/5

= 245

Plum trees = 175

Pear trees = 245

Apple trees = 600 - (175 + 245)

= 600 - 420

= 180

Fraction of apple trees = Number of apple trees / Total number of trees

= 180/600

= 3/10

Apply the distributive property to simplify the expression 7(11-7).

Answers

Answer:

28

Step-by-step explanation:

The Distributive property uses the number outside the parenthesis and combines it (using multiplication) with the ones inside.

So, the number 7 will be multiplied with the numbers inside the parenthesis.

7(11-7)

7 × 11 = 77

7 × -7 = -49 (It will just be the same way you multiply but with a added negative sign.)

77-49=

a woman is 5 times as old as her daughter in 15 years time to be two times as old as her daughter to find a mother's presentsage​

Answers

Answer:

25 years.

Step-by-step explanation:

Given that a woman is 5 times as old as her daughter, while in 15 years time it will be two times as old as her daughter, to find a mother's presents age the following calculation must be performed:

5 x 5 = 25

25 + 15 = 40

40/2 = 20

5 + 15 = 20

Thus, the present age of the mother is 25 years, while that of her daughter is 5 years, with which the mother is five times the age of her daughter. In 15 years, the mother will be 40 and her daughter 20, with which she will only be twice her age.

If x and y vary directly and x=25 when y=100 find x when y=24.
PLEASE HELP FASTTTTTTT

Answers

Answer:

x = 6

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 25 when y = 100 , then

100 = 25k ( divide both sides by 25 )

4 = k

y = 4x ← equation of variation

When y = 24 , then

24 = 4x ( divide both sides by 4 )

ALL OUR ARTS AND OCCUPATIONS LIE WHOLLY ON THE SURFACE; IT IS ON THE SURFACE THAT WE PERCEIVE THEIR BEAUTY, FITNESS, AND SIGNIFICANCE; AND TO PRY BELOW IS TO BE APPALLED BY THEIR EMPTINESS AND SHOCKED BY THE COARSENESS OF THE STRING AND PULLEYS. In a similar way, psychology itself, when pushed to any nicety, discovers an abhorrent baldness, but rather from the fault of our analysis than from any poverty native to the mind. And perhaps in aesthetics the reason is the same: those disclosures which seem fatal to the dignity of art seem so perhaps only in the proportion of our ignorance; and those conscious and unconscious artifices which it seems unworthy of the serious artist to employ were yet, if we had the power to trace them to their springs, indications of a delicacy of the sense finer than we conceive, and hints of ancient harmonies in nature.
