A large cheese pizza costs $7.50. Diego has $40 to spend on pizzas. How many large cheese pizzas can he afford?
Answer:
5
Step-by-step explanation:
40 / 7.50 = 5.333
since he can't by a third of a pizza, he can afford 5 large cheese pizzas
HOPE THIS MAKES SENSE & HELPS!!!
Answer: 5 pizzas
Step-by-step explanation:
We can do the floor of 40/7.5.
40/7.5 = 5.33333.
As he cannot buy 1/3 of a pizza, he can afford 5 pizzas.

The length of a rectangle is 4m longer than its width.
If the perimeter of the rectangle is 56m, find its length and width.
Call the length a, the width b
Perimeter = (a+b) x 2
We have : a - b = 4 and (a+b) x 2 = 56
-> a + b = 28
-> a - b = 4
=> a+b + (a-b) = 32
2a = 32
a = 16
b = 56:2-16 = 12
So, the length = 16 and the width = 12

A number cube has 5 green sides and 1 orange side.

1. What is the probability of 2 green outcomes and 2 orange outcomes when you roll the number cube 4 times?
The probability of 2 green outcomes and 2 orange outcomes when you roll the number cube 4 times is 0.116.
How to find the probability?Assuming that it is a fair number cube, the probability of getting green is given by the quotient between the outcomes that give the color green and the total number of outcomes.
We know that there are 5 green sides (so 5 outcomes give the color green) and the dice has 6 sides (so there is a total of 6 outcomes). Then the probability of rolling green is:
P = 5/6.
The probability of rolling orange is computed in the same way, 1 outcome gives the color orange and there are 6 outcomes in total, so the probability of getting orange is:
Q = 1/6.
Now, let's assume that when we roll four times we get:
green - green - orange - orange.
The probability of that is given by the product of the individual probabilities, it is:
p = P*P*Q*Q = (5/6)*(5/6)*(1/6)*(1/6).
Now, we also need to take in account all the possible permutations, these are:
green - green - orange - orange.green - orange - green - orange.green - orange - orange - greenorange - green - green - orangeorange - green - orange - greenorange - orange - green - green.So there are 6 permutations, to get the total probability of rolling 2 green outcomes and 2 orange outcomes, we need to multiply this number by the probability we got above.
Probability = 6p = 6* (5/6)*(5/6)*(1/6)*(1/6) = 0.116

Lisa and complains a lot about her drink being flat infact local restaurant manager can consider banning her for making spurious complaints but then if he wondered if you should put forward for quality control job with the fizzy drinks company . if Lisa says a drink is flat how likely is she to be correct how good is he sad setting whether or not a drink is flat would Lisa be good at the quality controlled job justify your answer
A) The probability of Lisa being correct if she says a drink is flat is; 83.3%
B) The level of Lisa's accuracy in detecting a drink that is flat is; 83.3%
C) The reason why Lisa should be considered for to job is because; she has a high accuracy level and is not just complaining unnecessarily.
How do you interpret the right probability?
From the table showing Lisa's response to the last 100 drinks she bought attached, we see that;
A) When the drink was flat, she complained 5 times out of 6. Thus, if the drink is flat, the probability of her complaint being correct = 5/6 = 83.3%
B) Since she is 83.3% correct in detecting whether a drink is flat, then we can say that Lisa is 83.3% very good at detecting whether a drink is flat.
C) It would be good in recommending Lisa for the quality control job because she only complained 3 times out of 94 times that the drink was not flat while she was correct 5 out of 6 times when the drink was flat. Thus, she has a high accuracy level and is not just complaining unnecessarily.

rectangle EFGH?
Answer:
57.2 units^2
Step-by-step explanation:
The coordinates provided form a parallelogram, not a rectangle. See the attached image for a diagram of EFGH. The area of a parallelogram is given by:
Area = (Base) x (Height)
The attachment explains an approach of using right triangles to find the base and height of the parallelogram.

The hypotenuse of a right triangle measures 18 cm and one of its legs measures 12 cm. Find the measure of the other leg. If necessary, round to the nearest tenth
Answer:
16 cm
Step-by-step explanation:
A right triangle, with the hypotenuse = 18, one side = 7, and the other side = x.
Since this is a right triangle, use the pythagorean theorem to find the value for x.
let a = 7 for one side, and let c = 18 for the hypotenuse. And, let c = x for the other side.
The pythagorean theorem is: c^2 = a^2 + b^2.
18^2 = 7^2 + x^2324 = 49 +x^2
x^2 = 324 - 49 = 275So, x = sqrt(275) = 16.5 cm

Step-by-step explanation:
Separate the figure into 3 rectangles by drawing vertical lines from the vertices.
Area of a rectangle = width x length
Total area = (18 x 23) + (23 x (23 - 7)) + (7 x 10)
= 414 + 368 + 70

What is the value of x, rounded to the nearest tenth?
Answer:
x ≈ 31.8
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 12² = 34²
x² + 144 = 1156 ( subtract 144 from both sides )
x² = 1012 ( take square root of both sides )
x = [tex]\sqrt{1012}[/tex] ≈ 31.8 ( to the nearest tenth )
Answer:
20.8
Step-by-step explanation:
[tex]24 = \sqrt{ {12}^{2} + {x}^{2} } [/tex]
[tex] {24}^{2} = 144 + {x}^{2} [/tex]
[tex]576 - 144 = {x}^{2} [/tex]
[tex] {x}^{2} = 432[/tex]

A cone has a height of 11 meters and a radius of 7 meters . What is the volume?
Answer:
V = 564.2 m^3
Step-by-step explanation:
The volume of a cone is given by
V = 1/3 pi r^2 h where r is the radius and h is the height
V = 1/3 pi (7)^2 (11)
V =539 /3 * pi
Letting pi be approximated by 3.14
V = 564.1533333 m^3
Rounding to the nearest tenth
V = 564.2 m^3
Answer:
564.512 m³
Step-by-step explanation:
Formula to find the volume of a cone is :
Volume = [tex]\frac{1}{3}[/tex] π r² h
Here,
r = radius = 7 m
h = height = 11 m
Let us solve now.
Volume = [tex]\frac{1}{3}[/tex] π r² h
Volume = [tex]\frac{1}{3}[/tex] π ×7² × 11
Volume = [tex]\frac{1}{3}[/tex] π × 49 × 11
Volume = [tex]\frac{1}{3}[/tex] π × 539
Volume = [tex]\frac{1}{3}[/tex] × 1693.538
Volume = 564.512 m³
