Answer:

12

Step-by-step explanation:

Perimeter is using addition and if its a square, all of the sides are the same.

If one side = 3 cm, then 3cm + 3cm + 3cm + 3cm=12 cm

Answer:

12

Step-by-step explanation:

A square with 3cm long side

Area = 2 sides multiplied

Perimeter = All sides added

3 + 3 + 3 + 3 = 12cm

or

3 × 4 = 12cm

Answer:

- [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

4x - y = 9 ( subtract 4x from both sides )

- y = - 4x + 9 ( multiply through by - 1 )

y = 4x - 9 ← in slope- intercept form

with slope m = 4

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{4}[/tex]

Answer:

scale factor = 4

Step-by-step explanation:

The scale factor is the ratio of OA' to OA , that is

scale factor = [tex]\frac{OA'}{OA}[/tex] = [tex]\frac{3+9}{3}[/tex] = [tex]\frac{12}{3}[/tex] = 4

Answer:

a = 3

Step-by-step explanation:

Here you can use the cross multiplication strategy or whatever it's called. That's where you multiply the diagonals together. Its kinda long to explain, but you can google it for details.

In either case, you get the following equation:

8(2a-1) = 4(a+7)

Open the parenthesis

16a - 8 = 4a + 28

Subtract 4a from both sides

12a - 8 = 28

Add 8 to both sides

12a = 36

Divide both sides by 12

a = 3

Answer: y=1.25x

Step-by-step explanation:

i got it right

Answer: y=1.25x, which equation represents the situtation.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

Here, given that,

The price of broccoli is $1.25 per pound.

Let, y be the total cost in dollars of buying x pound of broccoli.

Hence, equation represents the situtation is y=1.25x.

This uses the cosine Law for line length.

Formula

a^2 = b^2 + c^2 - 2*b*c*sin(A)

Givens

a  = 5

b = 7

c = 10

Solution

5^2 = 7^2 + 10^2 - 2*7*10*cos(A)

25 = 49 + 100 - 140*cos(A)                  Combine the right side

25 = 149 - 140 * cos(A)                         Subtract 149 from both sides

25 - 149 = - 140*cos(A)                    

-124 = -140 * cos(A)                               Divide both sides by -140

-124/-140 = cos(A)

Cos(A) = 0.8857                                   Take the inverse Cos of both sides

A = cos-1(0.8857)

Answer

A = 27.66 degrees

In the top row, first column the answer is D) Ray RQ and Ray RS. Opposite rays point in complete opposite directions. When joined, opposite rays form a line.

-----------

In the top row, second column, the answer is B) S, T, U. We're naming three points that all fall on the same line.

===============================================

In the bottom row, first column, the answer is A) Point. An example of this is the diagram in the bottom right corner. The lines WV and XZ intersect at the point Y.

-----------

Finally, in the bottom row, second column, the answer is D) Ray YW and Ray YV. Like with the first problem, we're listing two rays that when joined, form a straight line. They point in complete opposite directions. The order matters when it comes to naming a ray. The first letter tells us the endpoint and the second letter tells us where the ray points and goes on forever.

Answer:

=> x = 2.4

Step-by-step explanation:

By using PGT

=> (5+x)² = 7²+x²

=> 5² +x² +2(5)(x) = 49+x²

=> 25 + x² + 10x = 49 +x²

=> 10x = 49-25

=> 10x = 24

=> x = 24/10

=> x = 2.4

3 equal angles

so the triangle is equilateral => 3 equal sides

4x-10 = 3x+2

x = 12

or

4x-10 = 5x-22

-x = -12

x = 12

or

5x - 22 = 3x + 2

2x = 24

x = 12

x = 12

Answer:

The value of x = 12

Step-by-step explanation:

This is an equilateral triangle and the sides of an equilateral triangle are equal .

By putting the two sides of the triangle equal , we can find out the value of x

=> 4x - 10 = 3x +2

=> 4x - 3x = 2 + 10

=> x = 12

6 pies are more in 60 to 89 cherries than 90 to 119 cherries, a bar graph is a graphical depiction of information, amounts, or numbers using bars or strips.

They are employed to contrast and compare various data kinds, frequencies, or other measurements of several categories of data.

here, we have,

The calculation of the bar graph in the given question.

For 60 - 89 cherries there are 10 pies

For 90 -119 cherries there are 4 pies

10 -4 = 6  pies

The image for the graph is attached below.

When displaying sections of data, bar charts should be used. As long as there aren't too many categories to compare, vertical bar charts can be useful for comparing several categories or discrete data, such as age groups, classes, schools, etc. They are quite helpful for time series data as well.

Therefore, there are 6 more pies in the 60 -89 cherries category than in the 90-119 category.
