Susan collected 89 stickers for 28 weeks. How many stickers did she collect in total round off your answer to the nearest hundred answer for free
Answer:
2500 ( nearest hundred)
Step-by-step explanation:
Given that :
Number of stickers collected per week = 89
Number of weeks for which stickers were being collected = 28
To obtain the total number of stickers collected, we take the product of the number of weeks for which the stickers were beug vcilled and the number of stickers collected per week
The number of stickers collected :
89 * 28 = 2492
2492 = 2500 ( nearest hundred)

If a dilation with a scale factor of 5 is performed to ADEF, what will be the
coordinates of the new triangle?
D(-5,-2)
E(-5,3)
F(2,3)
o D'(-25,-10) E'(-25,15) F(10,15)
o D'(-20,-10) E'(-20,15) F'(5,15)
o D'(-1,5) E'(-1,3) F'(5,3)
Answer: · D'(-25,-10) E'(-25,15) F'(10,15)
Answer:
o D'(-25,-10) E'(-25,15) F'(10,15)
Step-by-step explanation:
In dilations, the scale factor is how many times larger than the new image will be.
Great, that explains a lot.
In other words, multiply the x and y-coordinate by the scale factor.
In this case, the scale factor is 5.
D(-5,-2)
-5 ⋅ 5 = -25
-2 ⋅ 5 = -10
E(-5,3)
-5 ⋅ 5 = -25
3 ⋅ 5 = 15
F(2,3)
2 ⋅ 5 = 10
3 ⋅ 5 = 15
Therefore, the new coordinates are:
D' (-25,-10)
E' (-25,15)
F' (10,15)

Find the Volume of a cylinder with a diameter of 16 inches and a height of 9 inches
Answer:
d = 16 in then r = 8 in
V = h * π * r²
V= 9in * π * (8 in)²
V = 1809.55 in³
Answer:
It's D
Step-by-step explanation:
A giant scoop, operated by a crane, is in the shape of a hemisphere of radius 24 inches. The scoop is filled with molten steel. The steel is then poured into a cylindrical storage tank with diameter 32 inches. How high will the molten steel rise?
Answer:
40 inches
Step-by-step explanation:
Volume, V of hemisphere = 2/3 π r^3
Radius, r = 24 inches ;
V = 2/3 π 24^3
V = 28952.917 in³
Volume of cylinder = π r^2 * h
h = height ; r = Radius = 32 /2 = 16 inches
Volume of hemisphere = volume of cylindrical tank
28952.917 = π (16)^2 * h
28952.917 = 804.24771h
h = 28952.917 / 804.24771
h = 35.9999
h = 40 inches
Molten stell rise is 40 inches
What would be for 7?
Answer:
Congruent segments subtracted from congruent segments form congruent segments
12 m Fence 17 m 20 m one can of weedkiller can cover 100 square metres. eachh can costs $19.75 work out the total cost of the cans of weedkiller needed to cover the lawn.
Answer:
Total amount needed is: $59.25
Step-by-step explanation:
Given
See attachment for fence
Required
Cost of weedkiller needed
First, we need to calculate the height of the fence.
Considering the triangular end of the fence, we have:
[tex]17 ^ 2 = h ^ 2 + 8 ^ 2[/tex] --- Pythagoras theorem
[tex]289 = h^2 + 64[/tex]
Collect like terms
[tex]h ^ 2 = 289 - 64[/tex]
[tex]h ^ 2 = 225[/tex]
Take positive square root of both sides
[tex]h = \sqrt{225[/tex]
[tex]h = 15[/tex]
Next, calculate the area of the fence (trapezium).
This is calculated as:
[tex]Area = \frac{1}{2}(a + b) * h[/tex]
Where:
[tex]a = 12[/tex]
[tex]b = 20 + 8 = 28[/tex]
So, we have:
[tex]Area = \frac{1}{2}(12 + 28) * 15[/tex]
[tex]Area = \frac{1}{2}(40) * 15[/tex]
[tex]Area = 20 * 15[/tex]
[tex]Area = 300m^2[/tex]
From the question, we have:
[tex]\$19.75 = 100m^2[/tex]
Let x = the cost required for the complete area
i.e.
[tex]x = 300m^2[/tex]
So, we have:
[tex]\$19.75 = 100m^2[/tex]
[tex]x = 300m^2[/tex]
Cross multiply
[tex]x * 100m^2 = \$19.75 * 300m^2[/tex]
Divide both sides by [tex]100m^2[/tex]
[tex]\frac{x * 100m^2}{100m^2} = \frac{\$19.75 * 300m^2}{100m^2}[/tex]
[tex]x = \frac{\$19.75 * 300m^2}{100m^2}[/tex]
[tex]x = \$19.75 * 3[/tex]
[tex]x = \$59.25[/tex]

Can the sides of a triangle have sides of 5, 8, and 16 ???
Answer:
No.
Step-by-step explanation:
The triangle inequality theorem states that the sum of two sides of a triangle must be greater than the third side.
5 + 8 = 13.
13, which is the sum of two sides, is not larger than 16, the third side.
Therefore, a triangle cannot have these side lengths.
If using the method of completing the square to solve the quadratic equation
x² + 2x + 16 = 0, which number would have to be added to "complete the
square"?
Answer:
x=-1+\sqrt{15}i,\:x=-1-\sqrt{15}i
Step-by-step explanation:
For the given quadratic equation,x² + 2x + 16 = 0 the value of x will be x=-1+√15i, and x-=-1-√15i you must add 1 in order to complete the square.
What is a quadratic equation?Any equation with the formula [tex]\rm ax2 + bx + c = 0[/tex] where x is a variable and a, b, and c are any real values; a quadratic equation is one where a ≠ 0.
It is given that the equation is, x² + 2x + 16 = 0,
The value of x obtained after solving the given equation is x=-1+√15i and x-=-1-√15i.
In order to complete the square you have to take out the following operations,
x² + 2x + 16 = 0
Add and subtract by 1 as
x²+2x+16+1-1
x²+2x+1 +15
(x+1)²+(√15)²
Thus, you must add 1 in order to complete the square.

Sean bought a laptop and a printer. He sold both items for £1,500 getting £1,350 just for the laptop. Sean made a 24% profit on the cost of the printer. What was the cost of the printer? Give your answer to 2 decimal places.
Answer:
36
Step-by-step explanation:
Sean purchased a printer and laptop
He sold both for 1,500
He sold the laptop at 1,350
Therefore the cost of the printer can be calculated as follows
1500-1350
= 150
24/100×150
= 0.24×150
= 36
Henve the cost of the printer is £36

Answer:
∠2 (∴ ∠3 is also correct)∠1∠1 (∴ ∠4 is also correct)Step-by-step explanation:
1) Both the angles ∠2 & ∠3 form a linear pair with ∠1. Also, angles of a linear pair are supplementary to each other. So, both ∠2 & ∠3 are supplementary to ∠1. (Write any one)
2) ∠1 is located vertically opposite to ∠4. So, ∠1 & ∠4 are vertical angles.
3) Both the angles ∠1 & ∠4 share a common vertex & common side with ∠3. So, both ∠1 & ∠4 are adjacent to ∠3. (Write any one)

If x and y vary inversely and x = 5 when y = -3.5, what is the value of x when y = 10?
Answer:
Step-by-step explanation:
k = xy
Putting values of x and y in the equation
k = (5)(-3.5)
= - 17.5
Finding value of x when y = 10
k = xy
- 17.5 = x10
Bringing like terms on one side
- 17.5 - 10 = x
-27.5 = x
A lawn sprinkler is set in the corner of the backyard. Thomas has the sprinkler set to rotate at 90 degrees. He knows that the sprinkler will spray 30 feet.

multiply sides by 4
k = 24
Answer:
k = 24
Step-by-step explanation:
k/4 = 6
k is being divided by 4, so multiply both sides by 4.
k/4 * 4 = 6 * 4
k = 24
A cylinder and a cone are shown below.
-
12 in.
-
12 in.
Volume of cylinder = 2512 in.
Volume of cone = 1256 in.
Which explains whether the bases of the cylinder and the cone have the same area?
O The bases have the same area because the heights are the same.
O The bases have the same area because the volume of the cone is 5 the volume of the cylinder.
O The bases do not have the same area because the volumes are not the same.
O The bases do not have the same area because the volume of the cylinder is not 3 times the volume of the cone, given
the same heights.
Answer:
The bases do not have the same area because the volume of the cylinder is not 3 times the volume of the cone, given the same heights.
Step-by-step explanation:
Recall :
V1 = volume of cylinder = πr²h
V2 = volume of a cone = 1/3πr²h
From the diagram, both have height, h of 12
Radius = r
V1 = 2512 in
V2 = 1256 in
From the ratio :
2512 = πr² * 12
1256 = 1/3πr² * 12
12 cancel out as well as r² and π
If the bases have the same area `, then 2512 should be equal to (1256 * 3)
2512 in ≠ 3868 in

5 x (12 - 6) divided by 2
Answer:
15
Step-by-step explanation:
according to PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction) you would do 12 minus 6 first resulting in the answer of 6 so your equation would then be 5 x 6 divided by 2. 5 x 6 comes next in the equation and thats 30 so your new equation is 30 divided by 2. 30 divided by 2 is 15.

9. The temperature of a liquid that is increasing can be represented by the equation
f(t) = 64 + 4t, where t is the time in hours. Graph the function to show the temperatures over the
first 10 hours. Use the graph to estimate the temperature after 7 hours.
Answer:
92°F
Step-by-step explanation:
in degrees Fahrenheit,
t=7
f(7)=64 + 4(7)
=92
The required temperature of liquid after 7 hours is 92.
Given that,
The temperature of a liquid that is increasing can be represented by the equation f(t) = 64 + 4t, where t is the time in hours. Graph the function to show the temperatures over the first 10 hours. To use the graph to estimate the temperature after 7 hours.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
f(t) = 64 + 4t
T = 7
f(7) = 64 + 4 * 7
= 64 + 28
= 92
Thus, the required temperature of liquid after 7 hours is 92.
