60 children were asked to chose their favourite vegetable from 5 options. Work out the number of children who chose each vegetable .
Answer:
carrots and cauliflower: 6
peas: 12
cabbage, sweetcorn: 18
Step-by-step explanation:
10 percent is 1/10, which is 6/60. Multiplied by two it's 12/60. Multiplied by 3 is 18/60.
One number is 10 less than twice another. If their difference is 31, what is the larger number?
step by step and no links please!!!!!!
MonarchAOP.com
Answer:
One number is 10 less than twice another.
This translates to n=2m-10
Their difference is 31
This translates to n-m=31
n-m=31
(2m-10)-m=31
m-10=31
m=41
n-41=31
n=72
Therefore the larger number is (B) 72
Step-by-step explanation:
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

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)

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.

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)
You rent an apartment that costs $1300 per month during the first year, but the rent is set to go up $120 per year. What would be the monthly rent during the 8th year of living in the apartment?
Answer:
2140
Step-by-step explanation:
Year one. 1300
year 2. 120. 1420
year 3. 120. 1540
year 4. 120. 1660
year 5. 120. 1780
year 6. 120. 1900
year 7. 120. 2020
year 8. 120. 2140
or
7 x 120=840
1300 + 840 = 2140

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.

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.

Volume= 216 cubic yards
Surface area: 276 square yards
Step-by-step explanation:
Find volume of rectangular prism:
V= lxwxh
V= 3x18x4
= 216 cubic yards
Find surface area:
SA= 2 x (front/back area) + 2 x (right/left area) and 2 x ( bottom/top area)
Front and Back Area:
A= l x w
A = 18 x 3
= 54 square yards
Right/ left Area:
4 x 3
= 12 square yards
Top/ Bottom Area:
18 x 4
= 72 square yards
54^2+12^2+72^2
