A.13/10
B.96
C.13/5
D.8/10
Answer:
the answer would be c
Step-by-step explanation:
The amount of pounds of pumpkin made in 30minutes is 96 pounds
Ratio and proportionsFractions are written as a ratio of two integers.
If Michael makes 16/5 pounds of pumpkin pie filling per minute, then;
16/5 pounds of pumpkin = 1 minutes
In order to determine the amount made in half an hour (30 mins)
x = 30mins
Take the ratios
16/5x = 1/30
5x = 480
x = 480/5
x = 96
Hence the amount of pounds of pumpkin made in 30minutes is 96 pounds

Answers:
a) First statement. Same as 1/2 x 6/11.
b) Second statement. Smaller than 6/11.
c) First statement. Same as 6/11 divided by 2.
================================================
Explanation:
Part (a)
The "of" means "multiply". So we simply replace "of" with the multiplication symbol and that's all we need to do.
---------------
Part (b)
Taking half of something will make it smaller. For example, if you have 100 cookies and you took half of them, then you'll be taking 50 cookies. The value 50 is smaller than 100.
The same idea applies to 1/2 x 6/11.
---------------
Part (c)
Multiplying by 1/2 is the same as dividing by 2.
So [tex]\frac{6}{11} \times \frac{1}{2} = \frac{6}{11} \div 2[/tex]
Note that [tex]\frac{1}{2} \times \frac{6}{11}[/tex] and [tex]\frac{6}{11}\times \frac{1}{2}[/tex] are the same thing because we can multiply two numbers in any order we want.
Answer:
a) First statement. Same as 1/2 x 6/11.
b) Second statement. Smaller than 6/11.
c) First statement. Same as 6/11 divided by 2.

An open box is formed from a rectangular piece of cardboard that is 5 in longer than it is wide, by removing squares of side 4 in from each corner and folding up the sides. If the volume of the carton is then 336 in what were the dimensions of the original piece of cardboard?
This question is incomplete
Complete Question
An open box is formed from a rectangular piece of cardboard that is 5 in. longer than it is wide, by removing squares of side 4 in. from each corner and folding up the sides. If the volume of the carton is then 336 in³, what were the dimensions of the original piece of cardboard?
Select one:
a. 15 in. by 20 in.
b. 7 in. by 12 in.
c. 11 in. by 16 in.
d. 19 in. by 24 in.
Answer:
a. 15 in. by 20 in.
Step-by-step explanation:
We are told that:
An open box is formed from a rectangular piece of cardboard that is 5 in longer than it is wide, by removing squares of side 4 in from each corner and folding up the sides.
Volume of the carton = 336 in³
Step 1
We find the area of the new piece of the cardboard
Volume of the carton/side of the square removed
= 336 in³/4 in
= 84 in²
Step 2
An open box is formed from a rectangular piece of cardboard that is 5 in longer than it is width.
Length = 5 + Width
Hence, we find the factors of 84 in² that has a difference of 5 in
Factors of 84 = 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42 and 84
Hence, the Factors with a difference of 5 inches = 7 and 12
The Length = 12 inches
Width is 7 inches.
The dimensions of the new piece of cardboard is 7 inches by 12 inches
Step 3
What were the dimensions of the original piece of cardboard?
Remember in the question, we are told that squares of sides 4 inches were removed from both corners
Hence,
4 inches + 4 inches = 8 inches was removed.
The dimensions of the original piece of cardboard =
Original Width = Width of the new cardboard + 8 inches
= 7 inches + 8 inches
= 15 inches.
Original length = Length of the the new cardboard + 8 inches
= 12 inches + 8 inches
= 20 inches.
Therefore, the dimensions of the original piece of cardboard is 15 inches by 20 inches

The speed of a rollercoastsr, in miles per hour, is modeled by the funtion g(x) = x⁴ - 4x² + 7x - 8, where x is time measured in seconds. How fast is the roller coaster travelling at 2 seconds?
Answer:
6mphStep-by-step explanation:
Given the expression
g(x) = x⁴ - 4x² + 7x - 8
we are expected to substitute x=2 into the expression and return the result
g(x) = (2)⁴ - 4(2)² + 7(2) - 8
g(x) = 16 - 4x4 + 14 - 8
g(x) = 16 - 16 + 14 - 8
g(x) =14 - 8
g(x) =6
From the substitution the roller coaster is travelling at speed of 6mph
Mrs. Grape has 90 students. On her last test, 3/10 of these students earned an A. Of those students, 1/9 got a perfect score. How many students got a perfect score?
Answer:
3 students
Step-by-step explanation:
Mrs. Grape has 90 students. On her last test, 3/10 of these students earned an A.
Hence, the number of students that had an A = 3/10 × 90
= 3 × 9 = 27 students
Of those students, 1/9 got a perfect score.
This means of the 27 students, 1/9 had a perfect score.
This means:
1/9 of 27 students = 1/9 × 27
= 3 students
How many students got a perfect score?
Hence, 3 students got a perfect score.
An urn contains 5 white and 3 black balls. Two balls are drawn at random without replacement. If X denotes the number of white balls, then find the probability distribution of X.
Answer:
Generally the probability distribution of the number of white balls (X) is
X 0 1 2
P(X) 0.35714 0.5357 0.10714
Step-by-step explanation:
From the question we are told that
The number of white balls is [tex]N_w = 5[/tex]
The number of black balls is [tex]N_b = 3[/tex]
Generally the total number of balls the urn contains is
[tex]N_t = N_w + N_b = 5 + 3 = 8 \ balls[/tex]
Generally the probability that of the two balls drawn that the balls are 2 white balls and 0 black balls is
[tex]P( 2_w \ , 0_b) = \frac{ ^{N_w} C _2 * ^{N_b} C _0 }{^{N_t} C_2}[/tex]
Here C stands for combination hence we would be making use of the combination feature in our calculator
=> [tex]P( 2_w \ , 0_b) = \frac{ ^5 C _2 * ^3 C _0 }{^{8} C_2}[/tex]
=> [tex]P( 2_w \ , 0_b) = 0.10714[/tex]
Generally the probability that of the two balls drawn that the balls are 1 white balls and 1 black balls is
[tex]P( 1_w \ , 1_b) = \frac{ ^{N_w} C _1 * ^{N_b} C _1 }{^{N_t} C_2}[/tex]
=> [tex]P( 1_w \ , 1_b) = \frac{ ^5 C _1 * ^3 C _1 }{^{8} C_2}[/tex]
=> [tex]P( 1_w \ , 1_b) = 0.5357[/tex]
Generally the probability that of the two balls drawn that the balls are 0 white balls and 2 black balls is
[tex]P( 0_w \ , 2_b) = \frac{ ^{N_w} C _0 * ^{N_b} C _2}{^{N_t} C_2}[/tex]
=> [tex]P( 0_w \ , 2_b) = \frac{ ^5 C _0 * ^3 C _2 }{^{8} C_2}[/tex]
=> [tex]P( 0_w \ , 2_b) = 0.35714[/tex]
Generally the probability distribution of the number of white balls (X) is
X 0 1 2
P(X) 0.35714 0.5357 0.10714

The Confederation Bridge connects News Brunswick to Prince Edward Island. The main part of the bridge rests on piers that form 43 segments. One segment is 8.2 x [tex]10^{2}[/tex] feet. What is the approximate length of the bridge in scientific notation?
Answer: [tex]3.5[/tex] × [tex]10^{4}[/tex]
Step-by-step explanation:
Write an expression to represent the problem.
(8.2 × 10²) × 43
= (8.2 × 10²) x (4.3 x [tex]10^{1}[/tex])
Now, multiply.
(8.2 × 10²) x (4.3 x [tex]10^{1}[/tex])
= (8.2 x 4.3) x ([tex]10^{2}[/tex] x [tex]10^{1}[/tex])
= 35.26 x [tex](10)^{2+1}[/tex]
= 35.26 x 10³
= 3.526 x [tex]10^{4}[/tex]
