1. Janet makes homemade dolls. Currently, she produces 23 dolls per
month. If she increased her production by 18%, how many dolls
would Janet produce each month? - ANSWER 🗸 First, calculate
18% of 23.
23 × 0.18 = 4.14
Then, add this value (the increase) to the original value of 23.
23 + 4.14 = 27.14
Rounding off, we get 27.
2. What is the formula for Area? - ANSWER 🗸 Area = L*W
3. Bill's new porch is rectangular, with an area of 50 square feet. If
the length of the porch is two times the width, what is the
perimeter of the porch? - ANSWER 🗸 The formula for the area of
a rectangle:
, A = Width * Length
4. From the question we know that L = 2W and that A = 50. So we
can plug these values into our equation and solve for W:
50 = W * L
50 = W * 2W
50 = 2W²
W² = 25
W=5
We know that L = 2W, so L = 10
Perimeter = 2L + 2W
Perimeter = 2 * 10 + 2 * 5
Perimeter = 30
5. 10 people can paint a building in 5 days. If each person paints as
quickly as the others then how much of the building could 7 people
paint in 5 days? - ANSWER 🗸 10 people can paint a building in 5
days. Each person paints 1/10 of the building in 5 days. In 5 days 7
people would paint 7 × 1/10 of the building In 5 days 7 people
would paint 7/10 of the building.
6. What is the x value such that y =15 - 3x and y = 0? - ANSWER 🗸
y =15 - 3x and y = 0
Hence 15 - 3x = 0
, Hence 3x = 15
X = 5 : The answer
7. Put these four fractions in order from smallest to largest: 1/4, 2/3,
4/7, 1/2 - ANSWER 🗸 If 1/4, 2/3, 4/7, 1/2 are converted to
decimals we get 0.25, 0.6666...., 0.571....., 0.5 then the correct
order is obvious
Or
If 1/4, 2/3, 4/7, 1/2 are converted to fractions with a common
denominator 21/84, 56/84, 48/84, 42/84 then the correct order is
obvious.
8. An isosceles triangle has two equal sides. If two of the sides are 5
inches and 2 inches how long is the perimeter? - ANSWER 🗸 The
other side must be 5 inches otherwise the two shorter sides could
not meet. The perimeter is the distance around the outside of the
triangle and is 5 + 5 + 2 = 12.
9. Elizabeth has a standard die that is labeled 1 to 6, and she rolls it
100 times. Which of the following experimental outcomes is NOT
likely?
67 rolls will show a number greater than 2.50 rolls will show an
even number.
