help on question 32 please
Answer:
90
Step-by-step explanation:
The mean is measured as
mean = [tex]\frac{score}{count}[/tex]
After 5 tests the mean is 84, that is
[tex]\frac{score}{5}[/tex] = 84 ( multiply both sides by 5 )
score = 420
let the sixth test score be x, then
[tex]\frac{420+x}{6}[/tex] = 85 ( multiply both sides by 6 )
420 + x = 510 ( subtract 420 from both sides )
x = 90
Require to score 90 on the sixth test
In the diagram shown below is it given (known) that FB and EH intersect at A and ZEAG is right. Give
two different angles that are both supplementary to ZFAH. What must be true of these two angles?
Answer:
Angle HAB and Angle FAE are congruent angles
Step-by-step explanation:
we know that
Two angles are supplementary if their sum is equal to 180 degrees
In this problem
m∠FAH+m∠HAB=180° ----> by a linear pair
Remember that
A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. A linear pair of angles must add up to 180 degrees
m∠FAH+m∠FAE=180° ----> by a linear pair
therefore
m∠HAB=m∠FAE -----> by vertical angles
Angle HAB and Angle FAE are congruent angles
Answer:
<HAB is congruent with <FAE

the formula F=ma means that the force on an object is equal to its mass times the acceleration. Solve F=ma for m
Answer:
Step-by-step explanation:
F = m / a
cross multiply
m = F /a
To solve F=ma for mass, divide both sides by acceleration to get m=F/a. For a wagon of 55 kg accelerating at 0.0255 m/s², the calculated force is 1.4025 newtons.
Explanation:To solve the formula F=ma for mass (m), you need to isolate the variable m. This is done by dividing both sides of the equation by acceleration (a), thus the rearranged formula becomes m = F/a. When we apply this to a practical example, if a wagon with mass 55 kg accelerates at a rate of 0.0255 m/s², the force on the wagon can be calculated using the same formula. By substituting the values into the formula, the force F is found as F = 55 kg × 0.0255 m/s², which equals 1.4025 newtons (N).

A ladder leaning against the side of a building touches the building at a point 12 meters from the ground. If the foot of the ladder is 18 meters from the base of the building, what is the slope of the ladder?
Answer:
The slope of the ladder to the building is 2/3
Step-by-step explanation:
* Lets explain how to find the the slope of the ladder
- A ladder leaning against the side of a building touches the building
at a point 12 meters from the ground
* That means the height of the ladder (h) from the ground is 12 m
- The foot of the ladder is 18 meters from the base of the building
* That means the horizontal distance (d) on the ground between the
ladder and the building is 18 m
- The slope of the ladder (m) , the height of the ladder (h) and the
horizontal distance on the ground from the base of the ladder to
the base of the building (d) can form a right triangle
∵ The slope of the ladder = the vertical distance/horizontal distance
∵ The vertical distance h is 12 meters
∵ the horizontal distance d is 18 meters
∴ The slope of the ladder [tex]m=\frac{12}{18}=\frac{2}{3}[/tex]
∴ The slope of the ladder to the building is 2/3
Answer:
2/3
Step-by-step explanation:
Its just as easy as it looks. Its 12/18, or Rise 12 and Run 18.
Solving would get you 2/3, so your slope is 2/3

Step-by-step explanation:
A roll of material is (x + 2) metres wide. Annie buys (x + 3) metres of the material and Bronwyn buys 5 metres of the material.
a) Write an expression, in terms of x, for the area of each piece of material purchased.
b) If Annie has bought more material than Bronwyn, write an expression for how much more she has than Bronwyn.
c) Factorise and simplify this expression.
d) Find the width of the material if Annie has 5m^2 more than Bronwyn.
e) How much material does each person have? Explain.
The problem involves determining the area of material purchased, comparing the quantities, and solving for the width given certain conditions. After setting up and solving the equations, it was found that the width of the material is 3 metres and the total amounts of material purchased by Annie and Bronwyn are 4 and 15 square metres respectively.
To solve the problems related to the area of material purchased by Annie and Bronwyn, follow these steps:
Area of material: Given the width of the material is (x + 2) metres, Annie buys (x + 3) metres long and Bronwyn buys 5 metres long. The area for each piece of material purchased is the product of the width and length. So, Annie's material area is (x + 2)(x + 3) square metres, and Bronwyn's material area is 5(x + 2) square metres.
More material: To express how much more material Annie has than Bronwyn, subtract Bronwyn's area from Annie's area, which gives us ((x + 2)(x + 3) - 5(x + 2)) square metres.
Factorisation: The expression for how much more material Annie has than Bronwyn can be factorized as (x + 2)(x - 2) square metres after simplifying.
Width of material: If Annie has 5 square metres more material than Bronwyn, we solve the equation (x + 2)(x - 2) = 5. Solving this quadratic equation gives x = 1, the width of the material is therefore 3 metres.
Total material: With x = 1, Annie purchases 4 square metres (since 3 x 1 + 3) and Bronwyn purchases 15 square metres (since 5 x 3). So, Annie has 4 square metres of material and Bronwyn has 15 square metres.
Trinity is going to the movies with some friends and will pay for her own ticket plus her own and her friends' small popcorns. Her total cost is given by the following expression: 8.5 + 6x What does the 6x represent?
A. The total cost of the small popcorns
B. The amount of small popcorns she is buying
C. The total cost
D. The cost of the ticket
Answer:
A. The total cost of the small popcorns
Step-by-step explanation:
Let us suppose Trinity is going to the movies with [tex]x[/tex] number of friends, we know she will pay for only her own movie ticket hence cost of movie ticket will be a constant (say [tex]a[/tex]) for her expense and cost of popcorn will be price of one popcorn (say [tex]b[/tex]) multiplied by number of friends.
considering the situation, her expense will be given by the function-
[tex]f(x) = a + bx[/tex]
comparing this with the given function [tex]8.5 + 6x[/tex], [tex]6x[/tex] will be the total cost of small popcorns.

(Hint which is the first number on both factors :))
Lauren will visit both the park and the library on the same day again after 30 days. This is because the least common multiple (LCM) of 3 and 10 is 30.
Explanation:The subject of this question is Mathematics, particularly dealing with the concept of least common multiple (LCM). The question is asking when will Lauren visit the park and the library on the same day again. Given that Lauren goes to the park every 3 days and the library every 10 days, the day when she'll do both again is the least common multiple of 3 and 10.
The least common multiple (LCM) is the smallest multiple that is exactly divisible by every member of a set of numbers. In this case, we need to determine the LCM of 3 and 10. The multiples of 3 are 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, ... The multiples of 10 are 10, 20, 30, 40, .... As we can see, the smallest number that appears in both lists is 30. Therefore, Lauren will visit both the park and library on the same day again after 30 days.

x+109 and x+89 what is x they need to be the same number when finished
Answer:
DNE (dose not exist)
Step-by-step explanation:
what you would do is just set both functions equal to each other and then solve for x. so set x+109=x+89. then get you numbers on one side and your x's on one side. so subtract x from on side getting x-x+89=109 now you subtract 89 from both sides getting x-x=109-89 getting 0= 20 0 dosen not = 20 so you would have zero there is no value that you could plug in for x to get them both equal

solve for x: x² - 14x + 49/x² - 49 = 3/17
Answer:
x = 10
Step-by-step explanation:
Begin by factorising the numerator/ denominator of the left side
x² - 14x + 49 = (x - 7)² ← perfect square
x² - 49 = (x - 7)(x + 7) ← difference of squares
Thus left side becomes
[tex]\frac{(x-7)^2}{(x-7)(x+7)}[/tex] → x ≠ ± 7
Cancel (x - 7) on numerator/denominator, leaving
[tex]\frac{x-7}{x+7}[/tex]
Returning to the equation, that is
[tex]\frac{x-7}{x+7}[/tex] = [tex]\frac{3}{17}[/tex] ( cross- multiply )
17(x - 7) = 3(x + 7) ← distribute both sides
17x - 119 = 3x + 21 ( subtract 3x from both sides )
14x - 119 = 21 ( add 119 to both sides )
14x = 140 ( divide both sides by 14 )
x = 10

The volume, V, of the right circular cone with radius r.
and height h, shown below, can be found using the
formula V= { ar?h. A cone-shaped paper cup has a
volume of 142 cubic centimeters and a height of
8.5 centimeters. What is the radius, to the nearest
centimeter, of the paper cup?
Answer:
radius^2 = 3 * Volume / (PI * height)
radius^2 = 3 * (142 cc / 3.14159265 * 8.5)
radius^2 = 3 * (142 cc / 26.703537525 )
radius^2 = 15.9529425493
radius = 4.0 cm
Step-by-step explanation:
Final answer:
The radius of a cone-shaped paper cup with a volume of 142 cubic centimeters and height of 8.5 centimeters is approximately 4 centimeters when rounded to the nearest centimeter.
Explanation:
To determine the radius of a paper cup that is a right circular cone with a given volume, we will use the formula for the volume of a cone V = (1/3) πr²h. The volume, V, is provided as 142 cubic centimeters, and the height, h, is 8.5 centimeters.
Rearrange the formula to solve for the radius, r, as follows:
Divide both sides by π and 8.5 to isolate ¹⁄₃r² on one side.
Multiply both sides by 3 to get rid of ¹⁄₃.
Take the square root of both sides to solve for r.
Once we have the value of r, we round it to the nearest centimeter as the question asks for an approximation to the nearest whole number.
Let's perform the calculation:
V = (1/3)πr²(8.5) => 142 = πr²(8.5/3)
142 = (π × 8.5/3)r²
142 / (π × 8.5/3) = r²
r² ≈ 142 / (3.14159 × 8.5/3)
r² ≈ 15.91549431
r ≈ √15.91549431 ≈ 3.99 cm
Round r to the nearest centimeter: r ≈ 4 centimeters

A point, beginning at (0,0), undergoes the following composition of translation. Write an ordered pair for the points final position. T<5,-7> and then T<-6,2>
Answer:
(-1,-5)
Step-by-step explanation:
Starting at (0,0), we perform the first translation:
T<5,-7> implies that we move the point 5 units to the right (in the x (horizontal) direction), and 7 units DOWN in the y <vertical) direction.
From there we do the second translation: T<-6,2>
which means: 6 units to the left (in the horizontal direction) which takes us to "-1" for the x value, and 2 units up (vertical) which takes us to -5 for the y value.
Therefore the new location is (-1,-5)
