Hi, Please Help Mewhat Are The Perimeter And Area Of The Shape And How Do You Solve Itthank You

Answers

Answer 1

Answer:

Perimeter: 22cm Area: 24cm^2

Step-by-step explanation:

To find perimeter we add all the sides together. There are two missing sides in this picture.

The bottom one is found by adding the two top lines 4 + 2 = 6

The one on the right can be found by subtracting the left line and the given right line 5 - 2 = 3.

Now we have all the lines, add them together we get 22cm!

Now, there are two ways to find the area. Of course I’m going to show the one I prefer.

Imagine the chunk in the top right is not missing; what would the area of the rectangle be? 30cm^2

And now what’s the area of the missing chunk?

Our given line multiplied by the one we calculated for: 6cm^2

Now subtract the whole rectangle minus the piece we are missing 30 - 6 = 24cm^2

Using the slope​ formula, find the slope of the line through the points (0,0) and (4,8) . Use pencil and paper. Explain how you can use mental math to find the slope of the line

Answers

Answer:

Look below! I hope this helps, and mark as brainliest please!

Step-by-step explanation:

The formula for slope is (y2-y1) divided by (x2-x1). So in this case, we have (8-0) divided by (4-0) so we get 8 over 4 and that is 2. So the slope is 2.

if f(x)= 3x-4, find f(-2) - f(3)​

Answers

Answer:

-15

Step-by-step explanation:

f(-2) = 3(-2) - 4 = -6 - 4 = -10

f(3) = 3(3) - 4 = 9 - 4 = 5

f(-2) - f(3)​ = -10 - 5 = -15

Keisha's cat had kittens. The line plot below shows the weight, in pounds, of each kitten.

What is the total weight of all the kittens that weighed 3/8

pound?

Answers

Answer:

the answer would be 1 7/8

Step-by-step explanation:

first you would count up the number of kittens that weighted 3/8 of a pound. You should have the number of 5, next you would multiply 5 × 3/8= 1.875 (as a decimal). Then you would convert that number into a mixed number (fraction) because all the answers are in mixed number form. You should get 1 7/8 because:

(1875÷125)(1000÷125) = 158 when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 18751000 is also equal to 1 7/8 when expressed as a mixed number.

I hope this helps!

Solution (x, y) i dont understand it

Answers

Answer:

(3, 3)

Step-by-step explanation:

I guess you're looking for a point that satisfies 2 functions (red and blue). That point is an intersection of these two functions, hence (3,3)

Answer:

[tex]\boxed{\boxed{(x,y)=(3,3)}}[/tex]

Step-by-step explanation:

to understand thisyou need to know about:system of linear equationgraphing system of linear equationtips and formulas:when we have two linear equation to find the value of x and y is called the system of linear equationwhen we have graph, the solutions of system of linear equation are the coordinates of two lines cross togetherlet's solve:

since you can see at "tips and formulas" what linear equation is and what the solutions are when you have graph

if you see the graph attentively, you can see that the blue line and the red line cross together at (3,3) coordinates

therefore

the solution of the system of linear equation is

(x,y)=(3,3)

I went to the store to buy candy for my family. If I bought a total of 42 pieces of candy and I give my family of five the most pieces of candy each, how many pieces of candy do I have leftover for myself?

Answers

you will have 2 pieces left for yourself.
because 42 divided by 5 will not give you a whole number you set aside two because 40 is divisible by 5 leaving you with the whole number of 8 pieces for each family member and two remaining for yourself.

Answers

Answer:

There are no solutions

Step-by-step explanation:

Answer:

no real solutions

Step-by-step explanation:

-2x + 9 - 3x = -5x + 3

First, combine like terms on each side.

-2x - 3x + 9 = -5x + 3

-5x + 9 = -5x + 3

Continue to combine the like terms from both sides.

0 = -6

The above expression is not true, therefore, there are no real solutions.

Jaimie is practicing for the long jump. Each week she makes 10 jumps and after each jump she records the distance, in meters, she reaches with each jump. Her results for this week are represented in the table below. Jump 1 2 3 4 5 6 7 8 9 10 Distance (m) 5.1 5.3 5.4 5.2 5.5 5.4 5.2 5.3 5.5 3.5 Jaimie then reviews her results and determines the mean and standard deviation so that she can compare her results from this week to her results from the previous week. Jaimie felt the 10th jump was not reflective of her ability because she stumbled before making the jump and decided to remove the 10th jump from her data set. Determine whether each statement describes the change that will occur to the mean and standard deviation from this week's results when Jaimie removes the 10th jump from her data set. Select Yes or No for each statement. Yes No Removing the 10th jump from her data set will cause her average jump distance to increase. Removing the 10th jump from her data set will cause her average jump distance to decrease. The standard deviation will increase because the jump distances will be more spread out. The standard deviation will decrease because the jump distances will be more clustered together.
