Answer:

Look down

Step-by-step explanation:

Draw a square, use a color to mark the perimeter so draw a colored line on the sides of the quare and mark that perimeter, say perimeter is the total distance around a figure. Shade in the inside of the square and label it area.

Say that area is the amount inside a figure, solved by multiplying the sides.

Answer:

Her son is 10 years old.

Step-by-step explanation:

Let son be x

Ellie is 4x

In 5 years time: Her son = x + 5

Ellie = 4x + 5

Given that she will then be 3 times as old as her son: 4x + 5 = 3(x + 5)

Solve x: 4x + 5 = 3(x + 5) ,4x + 5 = 3x + 15

x = 10

Answer: 13

Step-by-step explanation:

First, we have to arrange the numbers in either ascending or descending order.

12,11,13,12,15,16, and 14 hours will then be: 11, 12, 12, 13, 14, 15 and 16.

The median will be gotten using the formula: = (n + 1) / 2

Since there are 7 numbers this will be:

= (n + 1) / 2

= (7 + 1) / 2

= 8/2

= 4th number

Since 13 is the 4th number, it's the median

The required cost of each golf shirt and golf shorts is $34.7 and 26.7 respectively.

Given that,
Cassandra sells merchandise at the local golf course. 35 golf shirts and 60 golf shorts cost $3,017.50 and 68 golf shirts and 180 golf shorts cost 8,149.09. To determine the cost of each golf shirt and golf shorts.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
let the cost of each golf shirt and golf short be x and y respectively
Accoding to the question,
35x + 60y = 3017.50   - - - - - - - (1)
68x + 180y = 8149.90   - - - - - - (2)

From equation 1
x = [3017.50 - 60y] / 35  - - - - -(3)
put x in equation 2
we get
y = $34.7
now put this y in equation 3
x = $26.7

Thus, the required cost of each golf shirt and golf shorts is $34.7 and 26.7 respectively.

Answer:

50.2 liters

Step-by-step explanation:

11 liters = 50km

Z liters = 228km

To get the value of Z, cross multiply

228 x 11 = Z x 50

2508 = 50z

Divide both sides by 50

2508/50 = 50z/50

50.16 = z

50.16 has two decimal places, so convert to 1 decimal place by approximation

50.16 = 50.2

Thus, 50.2 liters will be enough for 228km

7 is positive so the relationship is increasing.

The statements describe a cylinder are

(i) It has two bases

(ii) It has one lateral face

(iii) Its lateral face is a rectangle

A cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance.

"The top and bottom of a cylinder are called the bases. The height h of a cylinder is the distance between the two bases."

"The lateral surface of an object is defined as the area of all the sides of the object, excluding the area of its base and top. For a cylinder, the lateral surface area is the curved surface that connects the base and the top."

Answer:

No

Step-by-step explanation:

Acute angles are angles that measure less than 90 degrees. Obtuse angles are angles that measure more than 90 degrees. However, there are other types of angles. Take a right angle for example. It measures exactly 90 degrees, therefore it is neither obtuse or acute. So, Anton's definition cannot be valid - there are still other angles that are not obtuse that don't qualify as acute, either.

Full question:

A recipe calls for 2 cups of milk for every 6 1/4 cups of flour. If you increase the flour to 43 3/4 cups, how many cups of milk will you use?

Answer:

14 cups of milk

Step-by-step explanation:

The question can be rephrased how many 6 1/4 cups of flour can we get in 43 3/4 cups of flour so that we find how many cups of milk required

6 1/4 = 25/4.

Also, 43 3/4 = 175/4

We could now divide 175/4 by 25/4 to get how many 6 1/4 cups of flour are in 43 3/4 cups of flour = 175/4 / 25/4 = 175/4×4/25= 7

This means that we have seven 6 1/4 cups of flour, therefore we require 7×2 = 14 cups of milk (given that we require 2 cups of milk for every 6 1/4 cups of flour)

Step-by-step explanation:

Solving

3x + -6y = 42

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6y' to each side of the equation.

3x + -6y + 6y = 42 + 6y

Combine like terms: -6y + 6y = 0

3x + 0 = 42 + 6y

3x = 42 + 6y

Divide each side by '3'.

x = 14 + 2y

Simplifying

x = 14 + 2y

The slope of the equation 3x +6y = 42 is - 1 / 2.

The slope of a line is the change in the dependent variable with respect to the change in the independent variable.

Therefore, the equation a line can be represented in slope intercept form as follows;

y = mx + b

where

Therefore,

3x + 6y = 42

6y = -3x + 42

divide both sides by 6

y = -3x / 6 + 42 / 6

y = - 1 / 2 x + 7

Therefore, the slope is - 1 / 2.

Answer:

y=1/4x+2.75

Step-by-step explanation:

two coordinates are: (5,4) and (-3,2)

the linear function is y=mx+b

m=slope

b=y-intercept

first, find the slope

the formula to find the slope is y2-y1/x2-x1

2-4/-3-5=

-2/-8=

1/4

Now you know 1/4 is the slope.  Plug that into the function

y=1/4x+b

Now find the y-intercept

to do that, take one of your coordinates and plug the x and y values into the function.

I will use (-3,2)

2=1/4(-3)+b

2=-3/4+b

11/4=b

(or 2.75 decimal form)

Plug the y-intercept into the function and you're done

y=1/4x+2.75
