Jessica has 3 cards in a bag, each marked with a letter. The letters are X, Y, and Z. Without
looking, she reaches into the bag, pulls out a card, and then puts the card back in the bag. If
Jessica does this 3 times, what is the probability she pulls out the X card first, then the Y card,
and then the Z card?
Answer:
1/27
Step-by-step explanation:
The chance of getting X is ⅓. The chance of getting X then Y is ⅓², or ⅑. Finally, the chance of getting X, then Y, then Z is ⅓³, or 1/27
Answer:
1/27

Of all the people at a community swimming pool, 54 are in the water and 66 are not in the water. What percentage of the people at the pool are in the water?
10%
45%
82%
55%
Answer: 45%.
Step-by-step explanation: When you solve problems like these, you need to make the total 100%. The total amount of people at the community pool is 120. 120 can be our 100%. 66 people aren't in the water and 54 are in the water. As you can see, less than half of the total number of people at the community swimming pool is in the water, which means that is 45%. The 66 people who aren't in the water are 55% of the total people that are at the community swimming pool. So in summary, 45% of the total people who are in the community swimming pool are in the water.

38
100
× x = 190
Multiplying both sides by 100 and dividing both sides by 38,
we have x = 190 ×

38
x = 500
If you are using a calculator, simply enter 190×100÷38, which will give you the answer.

The deli scale weighs meat and cheese in hundredths of a pound. Sam put 5/10 pound of pepperoni on the deli scale. What weight does the deli scale show?
Answer: If we simplify the given weight of the pepperoni, we divide the numerator by the denominator. The answer to the division is 5/10 or 0.5. Then, since the weight is asked in unit of hundredths, the final answer would be 2.5.Â

If line m || line n and Ð2 measures 35°, what is the measure of Ð5?
Answer:
145
Step-by-step explanation:
angle 2 = angle 3
=> angle 3 = 35
now, we have
=> 35+angle 5 = 180
=> angle 5 = 180 - 35
=> angle 5 = 145
Answer:
145°
Step-by-step explanation:
line m || line (Given)
[tex]m\angle 2 = 35\degree ......(1)[/tex] (Given)
[tex]m\angle 3 = m\angle 2 ......(2)[/tex] (vertical angles)
From equations (1) and (2)
[tex]\implies m\angle 3 = 35\degree[/tex]
[tex]m\angle 3 +m\angle 5 = 180\degree[/tex] (interior angles on the same side of transversal)
[tex] \implies 35\degree +m\angle 5 = 180\degree[/tex]
[tex] \implies m\angle 5 = 180\degree-35\degree[/tex]
[tex] \implies m\angle 5 = 145\degree[/tex]

A right prism has a triangular base. The length of the base is 12 yards and the height of the base is 3 yards. The height of the prism is 3.5 yards.
What is the volume of the prism?
39.5 yd³
52.5 yd³
63 yd³
126 yd³
The volume of prism is,
⇒ V = 126 yards²
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A right prism has a triangular base. The length of the base is 12 yards and the height of the base is 3 yards. The height of the prism is 3.5 yards.
We know that;
The volume of prism is,
⇒ V = B × H
Where, B is the area of the base and h is the height of the prism.
Hence, We get;
The volume of prism is,
⇒ V = 12 × 3 × 3.5
⇒ V = 126 yards²
Thus, The volume of prism is,
⇒ V = 126 yards²

The stem-and-leaf plot lists the number of different ingredients found in different industrial cleaners. How many cleaners had more than 80 ingredients? Enter the answer in the box. cleaners
If your answer is incorrect then you do not get brainly
Answer:
Step-by-step explanation:
A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit).
Since the key says 4|0= 40 the answer to your question is 12. Twelve cleaners have more than 80 ingredients.
Answer: 12.
Step-by-step explanation: According to the key, 4|0 means 40, which applies to any other stem and leaf on the chart. For example, on the chart, any numbers to the other side of the 8 are more than 0 which can be 8|2 or 8|5, so those count. 9|0 or 90, is way bigger than 80, so any numbers next to 90 count as well. I circled all the numbers that are correct, which is 12.

Answer:
x ≤ 40
Step-by-step explanation:
Given:
[tex]\displaystyle \large{\dfrac{x}{-8} \geq -5}[/tex]
Multiply both sides by -8 to get clear out the denominator:
[tex]\displaystyle \large{\dfrac{x}{-8}\cdot (-8) \geq -5\cdot (-8)}\\\displaystyle \large{x\geq 40}[/tex]
Because the LHS (Left-Handed Side) expression is in negative, make sure not to forget to swap the sign from ≥ to ≤
Hence, the solution is x ≤ 40

Susan has two dogs named Murphy and Fido. She feeds each of them the same type of dog food. Murphy eats 2/3 of a can of dog food each day. Fido eats 1/2 of a can of dog food each day. Each can of dog food costs $1.75. The pet store is offering a sale that allows customers to buy one can of food and get one free. Susan wants to buy a 60-day supply of dog food during the sale. To the nearest cent, what would be the cost of Susan's dog food purchase before tax?
Answer:
$61.25
Step-by-step explanation:
The quantity for a 60-day supply is 60 times the 1-day usage. The BOGO offer means the sale price is effectively half the usual price.
__
One day supply: 2/3 can + 1/2 can = (4/6 +3/6) = 7/6 can
60-day supply: 60 × 7/6 can = 70 cans
Susan will be paying for 70/2 = 35 cans of dog food. (She will get 35 cans free.) So, her cost will be ...
35 × $1.75 = $61.25
The cost of Susan's dog food purchase would be $61.25 before tax.

Calculate the snow load for the low-slop (flat) roof. For this structure, we will use the following coefficients. Cs = 1.0 Ce = 1.0 Ct = 1.0 Is = 1.1 Pg = 25
Answer:
The width of member is as follows:
b = 3 ft
b = 3 × 12 in.
b= 36 in.
The depth of member is as follows:
d = 8 ft
d = 8 × 12 in.
d=96 in.
Since the structure used is Douglas fir-Larch lumber of size 3 × 8 size. Hence, tensile strength, f =1000 psi
Calculate the net area of the member as follows:
A = (b - ∅) × d
A= (36 - 7/8) × 96
[tex]A = 3372in^{2}[/tex]
Calculate the maximum axial tensile load by ASD method as follows:
