Part A : D.)
Part B : Length of the sandbox is 10 feet.
Step-by-step explanation:
Given,
Perimeter = 29 ft
We need to find the equation for the perimeter and also the length of the sandbox.
Solution,
Let the width of the sandbox be 'w'.
Now as per question said;
The length of the sandbox is 1 foot longer than twice the width of the sandbox.
So we can say that;
Length =
Now we know that the perimeter is equal to the sum of twice of length and width.
framing in equation form, we get;
Perimeter =
we have given the perimeter, so on substituting the value, we get;
Hence The equation used to find the width is .
Now we solve for 'w'.
Applying distributive property, we get;
Subtracting both side by '2' we get
Dividing both side by 6 we get;
Width of the sandbox = 4.5 ft
Length of the sandbox =
Hence Length of the sandbox is 10 feet.

the heights of five basketball players are 184 cm, 190 cm, 198 cm, and 202 cm. what is the average height of the five players?
Answer:
93.5
Step-by-step explanation:
Also you only wrote down four numbers not 5 so I calculated it using those four numbers
Answer: 193.5
Step-by-step explanation:
184 + 190 + 198 + 202 = 774
first we add all the numbers together
774/4 = 193.5
then we divide the numbers by the amount of things we have in this case we have four players (last basketball player height not given) so we divide that by our added number and get 193.5cm

Straight Line Graphs

Overview
Answer:
a) linked a screenshot of the graph.
b) when y=1 x=.5
Step-by-step explanation:
4 is the slope, which makes the graph angle different. Starting at the origin (0,0) if you go over 1 and up 4 that is how you can draw the slope on a graph.
-1 makes the line go to the right 1 time so instead of the graph being on the origin (0,0) it will be placed on the coordinate points of (1,0)
To find the x value. Find 1 on the y-axis of the line graph. Go to the right to find where the line intersects. After you find that go straight down to find the x-value (0.5)
What is the distance between the
points (-8, -3) and
(-2, -5)?
Question
What is the distance between the
points (-8, -3) and (-2, -5)?
Answer:
let the distance between the points be A(-8, -3) = x_1 ,y_1 and B (-2, -5)
= x_2 ,y_2.
Now,
According to the Pythagoras theorem,
d = √ (x _2 −x _1 )^2+(y _2 −y _1 )^2d=√(-2-(-8))^2 + (-5(-3))^2d= √(6)^2 + (15)^2d= √36+225d= √261d= 3√29Therefore d(distance) = 3√29
what is 98 divided by 5
Answer:
19.6
Step-by-step explanation:
the answer to the question is 19.6
Answer:
19.6
Step-by-step explanation:
We have to do long devision:
5 goes into 9 how many times? Once. So our first number will be one.
9 - 5(1) = 4
Bring the 4 down. Then bring the 8 from 98 down.
5 goes into 48 how many times? Nine times. So our second number will be nine.
48 - 5(9) = 3
Bring the 3 down. Since there is no numbers left from 98, add a decimal and then a zero to make the number 98.0.
5 goes into 30 how many times? Six times. So our third number will be six. Don't forget to add the decimal before the six!
30 - 5(6) = 0

H(x) = 1/x+2 and k(x) = 3x - 4
h[k(x)] =
A.(3x - 4)/(x+2)
B. 1/(4x - 2)
C. 1/(3x - 2)
Answer:
= 1/ (3x-2)
Step-by-step explanation:
H(x) = 1/(x+2)
k(x) = 3x - 4
h[k(x)] = place the function k(x) in for x in the function h(x)
= 1/(3x-4 +2)
Combine like terms
= 1/ (3x-2)
Hey there! I'm happy to help!
What we need to do is take the value of k(x) which is 3x-4 and plug it into the function h(x).
This is because our x in the function h[k(x)] is k(x), so we will substitute that value for x in that formula and that will give us our answer.
H[(k(x)]=1/(3x-4+2)
And combine like terms
H[(k(x)]=1/(3x-2)
So, our answer is C. 1/(3x-2)

slope formula is y2-y1 / x2-x1
let’s make 5, x1 and -1, x2, 4, x2 and -3, y2.
if you plug the numbers in it should look like
-3 - -1 / 4-5 = -2/-1 = 2 (positive two). it’s a positive 2 because a negative times a negative is a positive and a positive times a negative is a negative

Carlos and Pamela are going on a road trip. They are driving a total of 650 miles in three days to reach the destination. They took it easy the first day. On the second day, they drove twice as many miles as the first day. On the third day, they drove 50 miles more than the second day. How many miles did they drive each day?
Answer:
Carlos and Pamela drove 120 miles on the first day, 240 miles on the second day, and 290 miles on the third day.
Step-by-step explanation:
Let x be the number of miles driven on the first day.
Then they drove twice as many miles, or 2x on the second day
and 50 miles more than the second day's, so 2x + 50
The total is 650 across all three days, so we'll take the sum.
x + 2x + (2x + 50) = 650
Combine like terms on the left
5x + 50 = 650
Subtract 50 on both sides
5x = 600
Divide by 5 on both sides
x = 120
Check work:
120 + 2(120) + 2(120) + 50 = 650
120 + 240 + 240 + 50 = 650
600 + 50 = 650
650 = 650
So they drove 120 miles on the first day
2*120 = 240 miles on the second day
and 2*120 + 50 = 240 + 50 = 290 miles on the third day
1. Identify each pair of angles as complimentary, supplementary, or neither.
Answer:
Neither
Step-by-step explanation:
One angle is 90
Another angle is 43
Complimentary angle: If sum of two angles is 90, then they are complimentary.
Supplementary angle: If sum of two angles is 180, then they are supplementary.
So, the above mentioned are neither of these

Write as an expression. The quantity 10 less than x, divided by 4
Answer:
[tex]\frac{x-10}{4}[/tex]
Step-by-step explanation:
When it says less then that means 10 is less than x. You can write divided by 4 either by putting it as a fraction or by using the division sign as "x-10 / 4."
The quantity 10 less than x, divided by 4 is mathematically given as (10 - x) / 4.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.
Division means the separation of something into different parts, sharing of something among different people, places, etc.
If the quantity 10 is less than x, then the expression will be
⇒ 10 - x
Then the quantity 10 less than x and divided by 4, then the expression will be
⇒ (10 - x) / 4
The quantity 10 less than x, divided by 4 is mathematically given as (10 - x) / 4.

Answer:
3/2
Step-by-step explanation:
Csc(theta) = 1/Sin(theta)
So we have to find the side opposite theta.
a = 3*sqrt(5)
b = ?
c = 9
a^2 + b^2 = c^2
(3sqrt(5)) ^2 + b^2 = 9^2
9*5 + b^2 = 81
b^2 = 81 = 45
b^2 = 36
sqrt(b^2) = sqrt(36)
b = 6
Sin(theta) = 6/9
Csc(theta) = 1 / sin(theta) = 9/6
Csc(theta = 3/2
Problem 3
Answer: 3/2=====================================================
Explanation:
Use the pythagorean theorem to find the length of the missing side.
[tex]a^2 + b^2 = c^2\\\\a^2 + (3\sqrt{5})^2 = 9^2\\\\a^2+3^2*(\sqrt{5})^2 = 9^2\\\\a^2 + 9(5) = 81\\\\a^2 + 45 = 81\\\\a^2 = 81-45\\\\a^2 = 36\\\\a = \sqrt{36}\\\\a = 6\\\\[/tex]
This is the length of the missing vertical side. This side is opposite the angle theta.
[tex]\csc = \text{cosecant}\\\\\csc(\theta) = \frac{\text{hypotenuse}}{\text{opposite}}\\\\\csc(\theta) = \frac{9}{6}\\\\\csc(\theta) = \frac{3*3}{3*2}\\\\\csc(\theta) = \frac{3}{2}\\\\[/tex]
Alternatively, you can compute it like this
[tex]\sin(\theta) = \frac{\text{opposite}}{\text{hypotenuse}}\\\\\sin(\theta) = \frac{6}{9}\\\\\sin(\theta) = \frac{2}{3}\\\\\csc(\theta) = \frac{1}{\sin(\theta)}\\\\\csc(\theta) = 1 \div \sin(\theta)\\\\\csc(\theta) = 1 \div \frac{2}{3}\\\\\csc(\theta) = \frac{3}{2}\\\\[/tex]
