Answer:
$17.58
step-by-step explanation:
20+20+10+10+10+0.10+0.10+0.10+0.01+0.01= 70.32
then divide 70.32 by 4
Question 3 options:
x equals 35 over 6
x equals 30 over 7
x equals 168 over 5
x equals 196 over 19
Answer:
Option 3) 24 is right.
Step-by-step explanation:
Given in the picture is a triangle LMN. sides are MN = 12, LN = 21 and LM = x cm
Also MO is the angle bisector of angle M.
By applying angle bisector theorem for triangles we get
LM/MN = LO/NO
i.e. x/12 = 14/7
Simplify to get x = 24
Hence option 3 is right
Verify:
Check whether angle bisector theorem is true.
The proportion LM/MN =24/12 = 2
The proportion LO/NO =14/7 =2
Both are equal and hence verified
B.m + 3s + 20 =50
C. m + 3s = 50
D. m + s + 50
Answer with Step-by-step explanation:
Points for 1 multiple choice question = 1
Then, points for m number of multiple choice questions = 1 × m = m
Points for 1 short answer = 3
Then points for s number of short answer question = 3 ×s = 3s
Total number of points = m + 3s
and the total number of points = 50
i.e. m + 3s = 50
Hence, correct option is:
C. m+3s=50
B. A rectangle has a length of 6 centimeters.
C. For every 2 red candies in a bag, there are 3 green candies.
D. A printing shop offers a 25% discount off the cost of making copies.
Answer:
C. For every 2 red candies in a bag, there are 3 green candies.
Step-by-step explanation:
Ratios are comparing two things in an order so having 2 red and 3 green would then move to 4 red and 6 green and so on.

Scaled figures are zoomed in or zoomed out (or just no zoom) versions of each other. The correct option is D.
Scaled figures are zoomed in or zoomed out (or just no zoom) versions of each other. They have scaled versions of each other, and by scale, we mean that each of their dimension(like height, width etc linear quantities) are constant multiple of their similar figure.
So, if a side of a figure is of length L units, and that of its similarfigure is of M units, then:
where 'k' will be called a scale factor.
The linear things grow linearly like length, height etc.
The quantities which are squares or multiple linear things twice grow by the square of the scale factor. Thus, we need to multiply or divide by k²
to get each other corresponding quantities from their similar figures' quantities.
So the area of the first figure = k² × the area of the second figure
Similarly, increasing product-derived quantities will need increased power of 'k' to get the corresponding quantity. Thus, for volume, it is k cubed. or
The volume of the first figure = k³ × volume of the second figure.
It is because we will need to multiply 3 linearquantities to get volume, which results in k getting multiplied 3 times, thus, cubed.
Given that the diameter of sphere A is 2 units, it is dilated by a scale factor of 3 to create sphere B. Therefore, the diameter of sphere B is,
Diameter of sphere B = 3 × Diameter of sphere A
= 3 × 2 units
= 6 units
Now, the ratio of diameters of the sphere and the volume of the sphere can be written as,
Hence, the correct option is D.

Answer:
1:27
Step-by-step explanation:
I will use solve in terms of pi
Know that Original volume * scale factor cubed = new volume.
The scale factor is 3 and 3^3 is 27,
Therefore the ratio is 1:27
Answer:
The number is 3
Step-by-step explanation:
Let x be the number
Add 12
(x+12)
Then multiply by 4
4(x+12)
This is equal to 60
4(x+12) = 60
Divide each side by 4
4(x+12)/4 = 60/4
x+12 = 15
Subtract 12 from each side
x+12-12 = 15-12
x = 3
=====================================================
Work Shown:
x = some unknown number
x+12 = adding 12 to the unknown number
4(x+12) = multiplying the previous sum by 4
4(x+12) = 60 .... set this equal to the desired result we want
Now solve for x. We will undo the steps done above to isolate x
----------------
4(x+12) = 60
x+12 = 60/4 .... divide both sides by 4 to undo "multiply by 4"
x+12 = 15
x = 15-12 .... undo "add 12" by subtracting 12 from both sides
x = 3
-----------------
The unknown number is 3
add 12 to it to get 3+12 = 15
multiply that sum by 4 to get 15*4 = 60
Answer is confirmed.
