John is twice as old as Mary. The sum of their ages is 21. How old is Mary?
Let J = John's age and M = Mary's age. Select the system equations that represents the problem.
J - 2M = 0
J = M + 2
M - 2J = 0
J + M = 21

Answers

Answer:

Mary is 7

Step-by-step explanation:

If their ages combined equals 21 and john is twice Mary’s age then johns age takes up 2/3 of 21. that would b 14. 14 is 2 x 7. and Mary is 7. 14+7=21. Mary is 7 years old

Correct answers are:

J + M = 21

J - 2M = 0

For a craft each student will need five rubber bands.There.There are eight students.Rubber bands come in bags of nine. How many will be needed?How many rubber bands will be left over?

Answers

Answer:

40 rubber bands are needed

5 rubber bands will be left from 5 bags of of rubber band

Step-by-step explanation:

Each student will need five rubber bands.

There are eight students

Total rubber bands needed = rubber bands per student × number of students

= 5 × 8

= 40

Total rubber bands needed = 40

Rubber bands come in bags of nine.

Number of bags needed = Total rubber bands needed / number of rubber bands in each bag

= 40 / 9

= 4.44 bags

It is impossible to get decimal number of rubber bands bag, so, the next whole number after 4 is 5

5 rubber bands bags will be bought which = 5 × 9

= 45 rubber bands

Only 40 rubber bands are needed

Left over rubber bands = 45 - 40

= 5 rubber bands

Jake walked all the way around the perimeter of a square playground that has sides n feet long, then he walked an additional 20 feet. Which person walked the same distance as Jake?

Answers

Options :

Sarah, who walked a straight distance of n+10 feet.

Nancy, who walked around a square garden measuring n+5 feet on each side.

Jules, who walked around a rectangular room measuring n feet wide and 10 feet long.

Billy, who walked around a square lot measuring 20 feet on each side

Answer:

Nancy, who walked around a square garden measuring n+5 feet on each side.

Step-by-step explanation:

Given that:

Jake walked round the perimeter of a square with sides n feets long

Additional distance walked = 20 feets

Perimeter of a square = 4n

Where n = Length of the side

Hence Jake's total distance :

Perimeter walked + additional distance

4n + 20 feets

Comparing to Distance walked by Nancy:

Side length of square garden = n+5

Perimeter of the garden = 4 * side length

Perimeter of the garden = 4 * (n + 5)

Perimeter of the garden = 4n + 20 feets

Hence, Nancy walked the same distance as Jake

A flagpole 12 meters tall casts a 24-meter shadow. Nearby, luke stands and is 4 meters tall. Determine the length of luka's shadow. Include all labels.

Answers

Answer:

8 meters

Step-by-step explanation:

This is a question that deals with Proportion

Height of flagpole/Shadow of flagpole = Height of Luke/Shadow of Luke

Length of the shadow of Luke = x

= 12/24 = 4/x

We cross Multiply

12 × x = 24 × 4

x = 24 × 4/12

x = 8 meters

Hence, the length of the shadow of Luke = 8 meters

Answer:

4x + 2 = 30

Step-by-step explanation:

To find the perimeter of a triangle, add up the length of all three sides of the triangle.

Here, the sides of the triangle are "x+6", "x+6", and "2x-10". When you add up all three sides of the triangle, it should be equal to the perimeter, 30. So:

(x+6) + (x+6) + (2x-10) = 30

We can simplify this equation:

(2 * (x+6)) + (2x-10) = 30

2x + 12 + 2x - 10 = 30

4x + 2 = 30

Answer D: 4x + 2 = 30

Answer: Yes

The answer is:

Yes, both of this is equivalent.

Step-by-step explanation:

For the reason and solution, here:

1) 4x+6/2+3=

Factor: 2(x+3)Simplify: 2x+6

2) 4x+9=

This cannot be factored or simplified.

For me, these two is equivalent because "4x+9" equivalent is 2x+6 and this is the same if you simplified 4x+6/2+3 so for me, the answer is yes.

A pitcher ok a baseball team is practicing his fast ball trying to ensure he hits the strike zone. He consistently releases the ball 3.4 feet high while he is pitching. The pitcher must aim for the ball to hit the ground approximately 58.8 feet from the pitcher's mound in order to stay in the strike zone. At what angle of depression, to the tenth of a degree, must he release the ball

Answers

Answer:

3.3°

Step-by-step explanation:

The set up of the question will give a right angled triangle where the height covered by the bal is the opposite side.

The length at which the pitcher hit the ground is the hypotenuse.

Given

Opposite side = 3.4m

Hypotenuse = 58.8m

Required

Angle of depression

Using SOH CAH TOA trigonometry identity

According to SOH,

Sin(theta) = opposite/hypotenuse

Sin(theta) = 3.4/58.8

Sin(theta) =0.05782

theta = sin^-1(0.05782)

theta = 3.32°

Hence the angle of depression that he must release the ball to nearest tenth is 3.3°

A shipping company charges a $3 flat fee for a package, plus a fee based on the weight of the package. The company charges $0.75 per pound, plus an additional $0.50 for every pound over 12 pounds. . George plans on sending a package that is over 12 pounds. He has $27 to spend on shipping. What is the maximum number of pounds that this package could be? The Maximum number of pounds is

Answers

Answer:

32 pounds

Step-by-step explanation:

$3 flat fee for a package, plus a fee based on the weight of the package. The company charges $0.75 per pound, plus an additional $0.50 for every pound over 12 pounds.

The first step would be to derived an equation

$3 + $0.75

3 + 0.75x

Where x = number of pounds

George plans on sending a package that is over 12 pounds. He has $27 to spend on shipping.

Hence,

3 + 0.75x = 27

0.75x + 3 = 27

0.75x = 27 - 3

0.75x = 24

x = 24/0.75

x = 32 pounds

The maximum number of pounds that this package could be is 32 pounds
