Rachel is making nachos for a party. The recipe calls for 23 cup of cheese for each plate of nachos. Part A How many full plates of nachos can Rachel make with 5 cups of cheese?
Answer: 0.22 plates
Step-by-step explanation:
Given that The recipe calls for 23 cup of cheese for each plate of nachos
1 plate = 23 cups
X plate = 5 cups
Cross multiply
5 = 23x
Make the x the subject of formula
X = 5/23
X = 0.22
Or 5/23 plate

Theater a sells popcorn in a rectangular prism theater B sells popcorn in a similar tub both cost five dollars which theater gives you a better deal find the volume of theater is popcorn
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the dimensions of tubs used by theatre A and B is missing.
However, I'll solve the question as follows.
First, it should be noted that the tub with highest volume gives the best deal.
This is so because both pop corns go for the same price of $5 and the tub with the highest volume contains more popcorn.
The volume of a rectangular prism is calculated by
Volume = Length * Breadth * Height
Take for instance, the dimension of tub A is length = 4cm, breadth = 5cm and height = 6cm
And the dimension of tub B is length = 3cm, breadth = 7cm and height = 5cm
The volume of tub A (theatre A) = 4cm * 5cm * 6cm
Volume = 120cm³
The volume of tub B (theatre B) = 3cm * 7cm * 5cm
Volume = 105cm³
Because the volume of tub A is greater than that of tube B, then tube A offers the best deal
If you apply this steps in your question, you'll arrive at the right answer.

16 cm
268 cm3
2,145 cm3
17,157 cm3
536 cm
Answer:
2145 cm3
Step-by-step explanation:
Volume is a three-dimensional scalar quantity. The volume of the sphere is 2,145 cm³.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of the sphere is given by the formula,
[tex]\text{Volume of the sphere} = \dfrac43 \pi r^3[/tex]
Given that the diameter of the sphere is 16 cm, therefore, the radius of the sphere is 8 cm. Now, the volume of the sphere can be written as,
[tex]\text{Volume of the sphere} = \dfrac43 \pi r^3[/tex]
[tex]=\dfrac43 \pi r^3\\\\=\dfrac43 \times \pi \times (8)^3\\\\= 2,144.66\ cm^3 \approx 2,145\ cm^3[/tex]
Hence, the volume of the sphere is 2,145 cm³.

~Set both factors to equal zero
x + 7 = 0
x + 5 = 0
~Solve for x in [ x + 7 = 0 ]
x + 7 = 0
x + 7 - 7 = 0 - 7

Find the distance between A and B.
A. 2√5 Units
B. √6 Units
C. 4 Units
D. 2√3 Units
Answer:
The result is [tex]d = 2\sqrt{5}[/tex] units.
Step-by-step explanation:
The coordinates for A and B:
A = (-2, 0)
B = (2, 2)
-To find the distance between A and B, you need the distance formula:
[tex]d = \sqrt{(x_{2} - x_{1})^2 + (y_{2}-y_{1})^2}[/tex] Where the first coordinate is [tex](x_{1},y_{1})[/tex] and the second coordinate is [tex](x_{2}, y_{2})[/tex].
-Use the coordinates A and B for the equation:
[tex]d = \sqrt{(2+2)^2 + (2-0)^2}[/tex]
-Then, you solve the equation:
[tex]d = \sqrt{(2+2)^2 + (2-0)^2}[/tex]
[tex]d = \sqrt{(4)^2 + (2)^2}[/tex]
[tex]d = \sqrt{16 + 4}[/tex]
[tex]d = \sqrt{20}[/tex]
[tex]d = 2\sqrt{5}[/tex]
So, therefore the distance is [tex]2\sqrt{5}[/tex] units.

A square pyramid has a base of total area of 144 m square root 2 and a volume of 384m cubic what is the slant height of the pyramid?
Answer:
Slant height of the pyramid = 11.66 m
Step-by-step explanation:
A squad pyramid has a volume of
V = ⅓ × (area of base) × (vertical height)
Area of the pyramid's square base = 144 m²
Volume = 384 m³
384 = ⅓ × 144 × (vertical height)
Vertical height = (3×384)/(144) = 8 m
But, the slant height of the square based pyramid forms a right angled triangle with the vertical height of the pyramid and the distance from the centre of the base of the pyramid to an edge of the pyramid.
The distance from the centre of the base of the pyramid to an edge of the pyramid = half of the length of the diagonal of the square base of the pyramid.
The diagonal of the square base of the pyramid also forms a right angled triangle with two sides of the square base of the pyramid.
Area of the square base of the pyramid = 144 m²
Area of a square = (side length)²
Side length = √(Area of the square) = √144 = 12 m
Using Pythagoras theorem,
(Length of the diagonal)² = 12² + 12² = 288
Length of the diagonal = (12√2) m
Half of the length of the diagonal of the square base = 6√2 m
Using Pythagoras theorem further
(Slant height of the pyramid)² = (vertical height of the pyramid)² + (Half of the length of the diagonal of the square base)²
(Slant height of the pyramid)² = 8² + (6√2)² = 64 + 72 = 136
Slant height of the pyramid = √136 = 11.66 m

Step-by-step explanation:
Given:
A spinner is divided into 4 sections using the colours: red, orange, yellow, and green. After 50 trials, the spinner landed on red 10 times, on orange 16 times, on yellow 6 times, and on green 18 times.
To find: probability of the spinner not landing on yellow
Solution:
Probability is the chance of occurrence of some event.
Total number of outcomes = 50
Number of favourable outcomes = 50 - 6 = 44
Probability of the spinner not landing on yellow = Number of favourable outcomes / Total number of outcomes = [tex]\frac{44}{50}=\frac{22}{25}=0.88[/tex]

Mindy deposits $250 into a savings account that pays simple interest. If the interest rate is 1.5%, what is her account balance at the end of a 2 years if she makes no withdrawals?
Answer:
Her account balance at the end of 2 years is $257.5.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
[tex]T = E + P[/tex]
In this question:
Deposit of $250, so [tex]P = 250[/tex]
Interest rate of 1.5%, so [tex]I = 0.015[/tex]
2 years, so [tex]t = 2[/tex]
Amount of interest earned:
[tex]E = P*I*t = 250*0.015*2 = 7.5[/tex]
Total amount:
[tex]T = E + P = 7.5 + 250 = 257.5[/tex]
Her account balance at the end of 2 years is $257.5.
a, b , c and d are four integers.
their mean is 8.
their mode is 7.
their median is 7.5.
find the four integers
The four integers are 7, 7, 8, 10
What are the integers ?
Four integers are a, b, c, d
Mean = Sum of integers/Total number of integers
= (a+b+c+d)/4
According to the question,
Mean = 8
i.e. (a+b+c+d)/4 = 8
⇒ a+b+c+d = 32 ......(1)
Median (for even no. of integers) = ([tex]\frac{n}{2}^{th} +(\frac{n}{2}+1)^{th}[/tex] term)/2
= (2nd+3rd term)/2
= (b+c)/2
According to the question,
Median = 7.5
i.e. (b+c)/2 = 7.5
⇒ b+c = 15 .....(2)
We know that, most frequent data is the mode.
So, mode = 7 means the number 7 occurs most frequently.
7 is not more than 2 times, because if 7 occurs 3 times, then 2nd & 3rd term will be 7 & median will be (7+7)/2 i.e. 7, so 3rd term must be larger than 7 to adjust the median value, which is 7.5
Then 1st two integers are 7 & 7
i.e. a = b = 7
Now, from (2), b+c = 15
⇒ 7+c=15
⇒ c =15-7
⇒ c = 8
Now, from (1) we get, a+b+c+d = 32
⇒ 7+7+8+d = 32
⇒ 22+d = 32
⇒ d = 32-22
⇒ d = 10
So, a = 7, b = 7, c = 8, d = 10
