Answer:
x = 108 because of supplementary angles
Step-by-step explanation:
Solving for x:
Since x and 72 are supplemenatry angles, they'll equal to 180, so:
x + 72 = 180
x = 180 - 72
x = 108

A rectangular prism has a volume of 175 in'. The height of the prism is 7 in. The base is a square. What is the length of a side of the base? please help
Answer:
a=5cm
Step-by-step explanation:
V=B*H
You will get base if you do this:
B=V:H
B=175:7
B=25
I'm not so good with English, side is probably a,so:
Formula for base: B=a²
Then a=√B
a=√25
a=5cm
I hope this helps.
A tea that is 20% jasmine is blended with a tea that is 15% jasmine. How many pounds of each tea are used to make 5lb of tea that is 18% jasmine?
Answer:
21
Step-by-step explanation:
The amount of each tea are used to make 5lb of tea that is 18% jasmine is 3 lb of first type of tea, and 2 lb of second type of tea.
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For this case, we can assume that:
x = number of pounds we mix first type of tea (tea with 20% jasmine)y = number of pounds we mix first type of tea (tea with 15% jasmine)Then, as the total weight of the mixture is 5 lb, thus:
[tex]x + y = 5[/tex]
18% jasmine in 5 lb of mixture = 20% jasmine in x lb of first tea + 15% jasmine in y lb of second tea
Comparing in terms of weight, we get:
[tex]\dfrac{5}{100}\times 18 = \dfrac{x}{100} \times 20 + \dfrac{y}{100} \times 15\\\\90 = 20x + 15y\\18 = 4x + 3y[/tex]
Thus, we get a system of two linear equations as;
[tex]x + y = 5\\4x + 3y =18[/tex]
From first equation, getting x in terms of y:
[tex]x = 5 -y[/tex]
Substituting this in second equation, we get:
[tex]4(5-y) + 3y = 18\\20-4y + 3y =18\\y = 2\\[/tex]
Putting this value in expression for x, we get:
[tex]x = 5-y = 5-2 = 3[/tex]
Thus, the amount of each tea are used to make 5lb of tea that is 18% jasmine is 3 lb of first type of tea, and 2 lb of second type of tea.

In DEF e = 100 inches f = 740 inches and angle D = 159°. Find the area of DEF to the nearest square inch
Answer:
13260 square inches
Step-by-step explanation:
In DEF e = 100 inches f = 740 inches and angle D = 159°. Find the area of DEF to the nearest square inch
The formula to solve the above question is
1/2absinθ
a = 100 inches
b = 740 inches
θ = 159°
The area of the triangle =
1/2 × 100 × 740 × sin 159°
= 13259.61 square inches
Approximately = 13260 square inches
Therefore, the area of DEF = 13260 square inches

Answer:
The Answer Is E!
Step-by-step explanation:
To solve this equation., you have to try every solution and the only one that perfectly completes both statements is answer E.
We subtract the $1.15 from $2.10 if this is the price of one taco, leaving the price of a small cup of coffees price ($2.10-$1.15=$0.95 for a small cup of coffee
To check it fits both statements, we multiply the price of one coffee by 3 ()$0.95×3=$2.85 for three small coffees\
Next, we multiply $1.15 (one taco) by 2 to fill in the expression ($1.15×2=$2.30)
Finally, we add both the prices of the 3 coffees and two tacos which adds up to a perfect $5.15, justifying the answer

For every 2 cups of lemonade, there are 5 cups of iced tea.
For every 3 cups of lemonade, there are 2 cups of iced tea.
For every 5 cups of lemonade, there are 2 cups of iced tea.
Answer:
Answer 2 would be true.
Step-by-step explanation:
Because our ratio is 2:5 (or 2 to 5 for easier understanding) we know that every 2 cups we use of lemonade, we pair with 5 cups of tea.

For every 2 cups of lemonade, there are 5 cups of iced tea.
The height of a falling pinecone can be represented by y = -16° +64 where t is the time in seconds
and y is the height of the pinecone in feet. Write and solve an equation to find the number of seconds it
will take for the pinecone to reach the ground.
A. 4 seconds
B. 6 seconds
C. 2 seconds
D. 1.5 seconds
Answer:
4 Seconds
Step-by-step explanation:
Let's say the height of the ground is set at y = 0.
Then, since 16 times 4 is 64, we substitute 4 for x.
But wait! x is being squared!
So we need to find out what squared is 4. It's 2.
So, with x being equal to two, y is equal to 0.
But what is the number of seconds? We actually got it first.
That means that the answer is 4.
The pinecone takes 4 seconds to reach the ground.
A biologist was studying a certain species of earthworm. She collected samples of 6 adults from 2 different populations and measured their lengths in centimeters. The data are shown below.
Sample 1: 26, 25, 27, 19, 24, 26
Sample 2: 24, 23, 24, 26, 25, 25
Compare the means and ranges of the data for the 2 samples. Use your comparison to conclude the samples. Show and explain your work.
CAN YOU EXPLAIN WHY ALSO CAN YOU DO THIS AS SOON AS POSSIBLE PLEASE AND THANK YOU?
Answer:
Calculating the means:
Sum each length from each sample and divide it by the number of worms.
Sample 1: 26 + 25 + 27 + 19 + 24 + 26 = 147/6 = 24.5
Sample 2: 24 + 23 + 24 + 26 + 25 + 25 = 24.5
They each have the same sample mean.
Ranges: Take the largest length and subtract the smallest.
Sample 1: 27 - 19 = 8
Sample 2: 26 - 23 = 3
Sample 1 has a greater range.

Tell whether the angles are adjacent or vertical. Then find the value of x.
Answer:
[tex]x = 25[/tex]
Step-by-step explanation:
The angles are vertical since they form from two lines crossing at a point and they share a same vertex.
Vertical angles are equal so
[tex]4x - 25 = 75[/tex]
[tex]4x = 100[/tex]
[tex]x = 25[/tex]

Consider function g.
g(x) = 5/x - 1 + 2
What is the average rate of change of function g over the interval [-4, 3]?
A. 1/2
B. -1/2
C. -7/2
D. 2
Answer:
Step-by-step explanation: The answer is 1/2. This is on the Odyssey online Algebra 2 mastery test.
The average rate of change of function g over the interval [-4, 3] will be;
⇒ 1/2
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The function g is,
⇒ g (x) = 5 / (x - 1) + 2
And, The interval is,
⇒ [ - 4, 3 ]
Now,
We know that;
The average rate of change of function at interval [a, b] is,
⇒ f (b) - f (a) / (b - a)
So, The average rate of change of function g over the interval [-4, 3] is,
⇒ g (3) - g (- 4) / (3 - (- 4))
Here, The function g is,
⇒ g (x) = 5 / (x - 1) + 2
Put x = 3;
⇒ g (3) = 5 / (3 - 1) + 2
= 5/2 + 2
= 4.5
Put x = - 4;
⇒ g (-4) = 5 / (- 4 - 1) + 2
= 5 / - 5 + 2
= - 1 + 2
= 1
So, WE get;
The average rate of change = (4.5 - 1) / 7
= 3.5 / 7
= 1/2

1. Jemima wants to make chocolate chip walnut brownles. Chocolate chips come in a 12oz bag that costs $3. Walnuts
come in a 4oz bag that costs $2. If Jemima needs three pounds of chocolate chips and walnuts combined, and has $15
to spend, how many bags of each can she buy?
Answer:
4 bags of chocolate chips and 1 bag of walnuts.
Step-by-step explanation:
Find how many ounces are in 3 pounds:
16 oz = 1 lb
16 oz × 3 = 3 lbs
48 oz = 3 lbs
Variable x = number of chocolate chips
Variable y = number of walnuts
4x + 1y = 15
Keep in mind it must equal up to 48 oz and be $15 or under.
4 bags × 12 oz = 48 oz
1 bag × 4 oz = 4 oz
48 oz + 4 oz = 52 oz > 48 oz
4 bags × $3 = $12
1 bag × $2 = $2
$12 + $2 = $14 < $15
Both requirements have been met.
