Answer:
The sides are 6, 6 and 9
Step-by-step explanation:
Isosoles triangles have two sides the same length, s
Here the third side is 3 meters longer (s + 3)
therefor the perimeter is
s + s + (s + 3) = 21
Combine like terms
3s + 3 = 21
Subtract 3 from both sides
3s = 18
Divide both sides by 3
s = 6
s + 3 = 9
The sides are 6, 6 and 9

Math HW Mr Thompson May 24
Answers:
B) 0A) 27D) 50See the diagram below.C) 143================================================
Explanations:
Refer to the top left corner of the table. This is the intersection of the "less than 1 year" column and "antlers" row.Add up everything in the "1 year or older" column to get 12+15 = 27.There are 0+12 = 12 deer with antlers, and 23+15 = 38 deer with no antlers. I'm adding across the rows. This in turn means there are 12+38 = 50 deer total. You could also add across the columns, meaning we have 0+23 = 23 deer less than 1 years old, and 12+15 = 27 deer that are 1 year or older. So we have 23+27 = 50 deer total. The explanation is lengthy. There's not much room here so I'll explain in the section below. Refer to the table below as well.Dividing everything by 143 will help us get the values into percentages. For instance, 62/143 = 0.4336 = 43.36% approximately represents the number of people who wear a belt and also wear a watch (top left corner).-----------
Explanation for problem 4
We have 68 people who split the check out of 122 total. That leaves 122-68 = 54 people who don't split the check. These two values are the row totals for rows 1 and 2 in that order. So you'll have 68 at the end of row 1, and 54 at the end of row 2. Refer to the diagram below.
We have 56 people who prefer to skip dessert, meaning 122-56 = 66 people who order desert. We'll have 66 followed by 56 along the first two items in the bottom row. The grand total 122 is in the bottom right corner. The 122 is both in the total row and total column.
Then we're told that 50 people order desert and split the check. We had 68 people split the check, leaving 68-50 = 18 people who split the check, but didn't get dessert. For the first row, we have the values 50, 18, and 68. Note that 50+18 = 68.
In the second row, we must have the values 16, 38, and 54 in that order. The blank spaces are filled in using the same ideas as I've discussed in previous paragraphs.
The terms in gray boxes represent the totals, which would be left out when forming the table in your final answer. Meaning you'll have a 2x2 table instead of a 3x3 table.

To make a number pattern yuan used the rule add 5 with whole numbers as the startjng point. Which stament must be true about yuans list of numbers?☜︎
Answer:
All elements of the dataset will be whole numbers
Step-by-step explanation:
Given
[tex]Rule \to Add\ 5[/tex]
[tex]Start = n[/tex] ---- whole number
Required
A true statement about the list
If the starting point is n, then the list elements are as follows:
[tex]n , n + 5, n + 10, n + 15,....[/tex]
Also, since n is a whole number and 5 (the rule) which is added to the dataset is also a whole number;
Then the other elements of the dataset will be whole numbers

In this table, Davis recorded how far he could throw balls of different weights.
He modeled the data with a linear best-fit function. He can throw a certain ball 30 feet. Approximately how many pounds would this ball weigh?
a. 7.5 pounds
b. 8.1 pounds
c. 8.6 pounds
d. 9.1 pounds
Answer:
Option C
Step-by-step explanation:
By using linear best fit calculator for the given data,
Equation of the line of best fit will be,
y = -5.2514x + 74.94413
Here, x = Weight of the ball
y = Distance thrown by Davis
Now substitute y = 30 feet to calculate the weight (x) of the ball.
30 = -5.2514x + 74.94413
5.2514x = 74.94413 - 30
5.2514x = 44.94413
x = 8.5585
x ≈ 8.6 pounds
Therefore, David can throw a ball 30 feet weighing 8.6 pounds.
Option C will be the answer.

Solve the following quadratic equation.
(x + 4)^2 = 25
A. x= 9 and r = -1
B. x= -9 and x = -1
C. x= -9 and x= 1
D. x = 9 and x = 1
Answer:
-9; 1
Step-by-step explanation:
x+4=5
x=5-4
x=1
x+4=-5
x=-5-4
x=-9
The solution of the quadratic equation (x + 4)^2 = 25 is x = -9 and x = 1
The correct answer is option (C)
What is quadratic equation?"It is a polynomial with degree 2. The general form of quadratic equation is ax²+ b x + c =0, where a, b, c are real numbers with a ≠ 0."
For given example,
We need to find the solution of the quadratic equation (x + 4)^2 = 25.
⇒ (x + 4)^2 = 25
⇒ x² + 2(4)(x) + (4)² = 25
⇒ x² + 8x + 16 = 25
⇒ x² + 8x - 9 = 0
⇒ x² + 9x - x - 9 = 0
⇒ x(x + 9) - 1(x + 9) = 0
⇒ (x + 9)(x - 1) = 0
⇒ x + 9 = 0 and x - 1 = 0
⇒ x = -9 and x = 1
The correct answer is option (C)

A deli orders ham and turkey. The ratio of the number of ham slices to the number of turkey slices is 2:3. What is the ratio of the number of turkey slices to the total of ahem and turkey slices
Answer:
3 :5
Step-by-step explanation:
A deli orders ham and turkey.
The ratio of the number of ham slices to the number of turkey slices is 2:3.
Hence:
Ham slices: Turkey slices
2:3
Sum of proportion = 2 + 3 = 5
Ratio of turkey slices = 3
Ratio of the total of ham and turkey slices = sum of proportion = 5
Therefore, the ratio of the number of turkey slices to the total of ham and turkey slices is

5. If two angles are complementary and one angle is 40°, what is the other angle?
6. If two angles are supplementary and one angle is 40°, what is the other angle?
5. complementary angles = 90°
90 - 40 = 50
50°
6. supplementary angles = 180°
180 - 40 = 140
140°
5) complimentary angles = 90
If one is 40 then the other is = 90-40= 50
6) Supplementary angles = 180
If one is 40 then the other is = 180 - 40 = 140
