Answer:
√(110 - n)
Step-by-step explanation:
This can't be simplified. All we can do here is re-write "square root of 110 - n" symbolically, which comes out to √(110 - n). The parentheses are essential for clarity.

Find the length of the unknown leg of the right triangle.
Answer:
Step-by-step explanation:
a² + b² = c²
side1² + side2² = hypotenuse² side 1 = 6.75 hypotenuse = 11.25
solve for side 2 = ???
side2² = hypotenuse² - side1²
side2 = [tex]\sqrt{hypotenuse^2 - side1^2}[/tex]
= √(11.25² - 6.75²)
= √(126.56 - 45.56)
= √(81)
side 2 = 9
2. The volume of a cylinder is 95 cubic centimeters. Which equation
can be used to find h, the height of the cylinderę Circle the correct
answer.
Given:
The volume of a cylinder is 95 cubic centimetres.
To find:
The equation that can be used to find h, the height of the cylinder.
Solution:
We know that, the volume of a cylinder is:
[tex]V=\pi r^2h[/tex]
We know that the base of the cylinder is a circle and the area of the circle is [tex]\pi r^2[/tex]. So, the base area of the cylinder is [tex]B=\pi r^2[/tex].
Now, volume of the cylinder is
[tex]V=Bh[/tex]
The volume of a cylinder is 95 cubic centimetres.
[tex]95=Bh[/tex]
[tex]\dfrac{95}{B}=h[/tex]
[tex]h=\dfrac{95}{B}[/tex]
Where B is the base area of the cylinder.
Therefore, the correct option is G.

Lindsey purchased a random sample of 25 tomatoes at the farmers market. The 95% confidence interval
for the mean weight of the tomatoes is 90.6 to 112.4 grams.
What is the Point Estimate?
What is the Margin of error?
Answer:
3 & 5
Step-by-step explanation:
The value of point estimate is 101.5 and value of margin of error is 10.9 gram if the Lindsey purchased a random sample of 25 tomatoes at the farmers market.
What is the margin of error(MOE)?It is defined as an error that provides an estimate of the percentage of errors in real statistical data.
The formula for finding the MOE:
[tex]\rm MOE = Z\times \dfrac{s}{\sqrt{n}}[/tex]
Where Z is the z-score at the confidence interval
s is the standard deviation
n is the number of samples.
Let's suppose m is a point estimate and ME is the margin of error.
The structure of the confidence interval is:
(m—ME, m + ME)
The given confidence interval is (90.6, 112.4)
Then, m—ME = 90.6 ..... (1)
m + ME = 112.4 ..... (2)
After solving equation (1) and (2) we get:
m = 101.5
ME = 10.9 grams
Thus, the value of point estimate is 101.5 and value of margin of error is 10.9 gram if the Lindsey purchased a random sample of 25 tomatoes at the farmers market.

Answer quick pls!!!!
An airplane descends 1.6 miles to an elevation of 8.05 miles. Find the elevation of the plane before its descent.
Answer:
9.65 miles
Step-by-step explanation:
Given:
Final elevation = 8.05 miles
Change in elevation = 1.6 miles
Let Initial elevation which is the elevation before descent = x
Initial elevation - change in = final elevation
(-ve) sign because it was a descent
x - 1.6 = 8.05
x = 8.05 + 1.6
x = 9.65 miles
Hence, elevation before descent is 9.65 miles

Write a SIMPLIFIED inequality for x that would give a rectangle with a length of 4 meters and a width of x+7 meters an area of more than 128 meters squared.
Answer:
128 > 4*(x + 7)
Step-by-step explanation:
Given the following data;
Length = 4 meters
Width = x + 7 meters
Area = 128 m²
Mathematically, the area of a rectangle is given by the formula;
Area of rectangle = length * width
Substituting into the formula, we have;
128 > 4*(x + 7)
128 > 4x + 28
128 - 28 > 4x
100 > 4x
Dividing both sides by 4, we have;
25 > x

2. Dianna can carry up to 15 lbs in her backpack.
Her lunch weighs 1 lb, her gym shoes weigh
2 lbs, and her books weigh 1.5 lbs each. Which
inequality shows how many books Dianna can
carry in her bag if she has her lunch and gym
shoes?
O A. 3 + 1.5b < 15
B. 1.5 + 3b < 15
C. 3 + 1.5b > 15
D. 1.5 + 3b < 15
Answer:
Answer is A. 3 + 1.5 b < 15.
Step-by-step explanation:
Look at the problem carefully. Variable (b) represents books, and it states that the books weigh 1.5 lbs each. So you add her lunch (1 lb) and her shoes (2 lbs) to get 3 lbs. Once you add it together, it's less than (<) 15 lbs.
I tried to make this as understandable as possible, hope it helps.

Answer:
17 cm
Step-by-step explanation:
P=2L+2W
L=22, P=78 we want to find W
78=2(22)+2W
78=44+2W
34=2W
W=17 cm
6: What is the volume of a cylinder
with a diameter of 10 feet and a
height of 8 feet? Use 3.14 for 1.
cubic feet
Answer: 628 cubic feet
Step-by-step explanation: First, find the area of the circle. Using the formula "TTr^2", you can find the area of the circle. Since the diameter is given, and not the radius, divide 10 by 2, and it gives you 5. Now, use the formula. 5 x 5 = 25, and then multiply it by 3.14 which gives you 78.5. Now that we have found the area of the circle, multiply the area by 8 to find the volume of the cylinder. 78.5 x 8 is 628 cubic feet, and that is the volume of the cylinder.

When a tree 8m high casts a shadow 3m long, how long is a shadow cast by a person 2m tall?
Answer:
3/4 meters
Step-by-step explanation:
We can use ratios to solve
8m 2 m
------- = -----------
3m x m
Using cross products
8*x = 3*2
Divide each side by 8
8x/8 = 6/8
3/4 meters
Answer:
x = 3/4 m
Step-by-step explanation:
Construct two similar right triangles that share an angle of elevation. The two vertical sides represent the heights of the person and the tree and are 2 m ad 8 m respectively. The two horizontal sides represent the shadow cast by the person and that cast by the tree, respectively. Because the triangles are similar, we can write the following equation of ratios:
8 m 3 m
--------- = --------
2 m x
... where x is the length of the shadow cast by the person.
Cross multiplying, we get:
8x = 6m, or x = 6/8 m, or x = 3/4 m
The two angles are congruent. Find x
