Answer:
Tuesday, 1: 30 pounds
Tuesday, 2: 40% of the apples
Tuesday, 3: x ( or any variable) + 8
Tuesday, 4: 9a-3b
Step-by-step explanation:
Since she weighs 38% of the normal weight, you multiply the decimal form to the original weight, which is 78. So .38 multiplied by 78 is 29.64, and rounding it to the nearest pound would make it go up to 30.
38%=.38
.38 x 78=29.64
29.64 rounded = 30
If 3/5 of the apples are ripe, that means that 2/5 are not. An easy way to turn this fraction into a percent is to make the number out of 100. Since 5 x 20 is 100, you multiple both the numerator and denominator by 20. 2 x 20 is 40, 5 x 20 is 100, hence 40/100. The numerator will be the percentage.
5/5-3/5 = 2/5
2/5 x 20/20 = 40/100
40/100 = 40%
The unknown score would become a variable, and since its increasing by 3 it is +8.
Since the perimeter is adding all sides, you'd add all of the equations. The 3a's times 3 would be 9a, and the -b would become -3b.
3a - b + 3a - b + 3a - b
9a - b - b - b
9a - 3b

The Jellybean company is building a new cylinder container with a height of 3.5 inches and a radius of
2 inches. It needs a diagonal divider to separate the two flavors it plans on packing per container. The
production of this divider is being outsourced for manufacturing. What should be the length of the
diagonal divider after removing ¼ of an inch from its top to accommodate for packaging decorative
paper?
Answer:
Length of diagonal paper is 5.15 inch.
Step-by-step explanation:
Please refer to the images attached.
As per the cylindrical image, we have radius given as 2 inches.
Height as 3.5 inches - 0.25 inches = 3.25 inches
If we look closely, we actually have a right angled triangle whose
Base = 2+2 = 4 inches
Height = 3.25 inches
And we have to find the hypotenuse of triangle:
According to pythagoras theorem:
[tex]Hypotenuse^{2} = Base^{2} + Height^{2}[/tex]
[tex]\text{ Diagonal}^{2} = 4^{2} + 3.25^{2}\\\Rightarrow 16 + 10.5625\\\Rightarrow 26.5625\\\Rightarrow \text{Diagonal = }5.15\ inch[/tex]
Hence, Length of diagonal paper required is 5.15 inch.

Maria bought an SUV for 21,000 dollars. Nancy bought a sedan for 2/3 as much. How much less did Nancy spend on her sedan?
Answer:
7000
Step-by-step explanation:
21,000*(2/3)=14000
21,000-14,000=7000
Answer:
7,000 dollars
Step-by-step explanation:
21,000 divided by 3 is 7,000 = 1/3
So 2/3 = 7,000 x 2 = 14,000
To find how much less Nancy spent on her sedan you do 21,000 - 14,000 = 7,000

Find the slope of the line which goes through the given points.
d
A(2,8) and B(2,6)
Answer:
Undefined
Step-by-step explanation:
A slope is found using the formula rise (change in y) over run (change in x). The change in x is 0, and the change in y is -2. The answer is -2/0, but dividing by 0 gives you undefined. Don't believe me? Look at the attached image.
Hope this helps!
Answer:
Undefined
Step-by-step explanation:
Use the formula:
[tex]m=\frac{y+2-y_1}{x_2-x_1}[/tex]
Plug in the numbers/coordinates accordingly:
[tex]m=\frac{6-8}{2-2}[/tex]
[tex]m=\frac{-2}{0}[/tex]
m = undefined
When x = 0, the slope is undefined.
Gideon asked 50 students at his middle school which option they would like for lunch: pizza, sandwiches or burritos. Ten students said pizza, 4 said sandwiches and the remaining students answered burritos. What percent of students in the school would you predict would choose burritos based on this survey?
Answer:
72% of students chose burritos
Step-by-step explanation:
first you would add up the total of kids that said they liked the other two options, which was pizza and sandwiches: 10+4=14
then you would take that number and subtract it from the total of all students: 50-14=36
and then you would take that number and divide it by 50: 36/50=.72
turn that into a percent and you'd get 72%

22
diameter of the smaller coin? Use for .
7
What is the first step to find the diameter of the smaller coin?
Answer:
First step will be option D.
Diameter of the smaller coin will be 2.45 cm
Step-by-step explanation:
Circumference of one coin = 8.03 cm
Circumference of the smaller coin = Circumference of the larger coin - 0.33
= 8.03 - 0.33
= 7.7 cm
Circumference of the smaller coin = 2πr = 7.7
r = [tex]\frac{7.7}{2\pi }[/tex]
r = [tex]\frac{7.7\times 7}{2\times 22}[/tex]
r = 1.225 cm
Diameter of the smaller coin = 2 × radius of the smaller coin
= 2 × 1.225
= 2.45 cm
Therefore, first step will be option D.
Diameter of the smaller coin will be 2.45 cm

What is the true solution to 2 In x=2 in 8
Answer:
x=2 is the true solution.
Step-by-step explanation:
We have been given the expression:
2\ln 4x=2\ln 8
Using:
n\ln m=\ln m^n
Our given expression becomes:
\ln{4x}^2=\ln{8^2}
Cancel ln from both sides we get:
4x^2=8^2
On simplification we get:
16x^2=64
x^2=4
Final simplification gives the result:
x=2
Answer:
x = 8
Step-by-step explanation:
2 In x=2 ln 8
Divide by 2
ln x = ln 8
Raise to the e base
e^ ln x = e^ ln 8
x = 8
Find an explicit formula for the geometric sequence 3, 15, 75, 375...
Answer:
3 * 5 ^ (n-1)
Step-by-step explanation:
3 is the first term and it multiplies by 5
The explicit formula for the geometric sequence is [tex]T_n = 3(5)^{n-1}[/tex]
The standard explicit formula for a geometric sequence is expressed as:
[tex]T_n = ar^{n-1}\\[/tex]
a is the first term
r is the common ratio
n is the number of terms
Given the sequence of numbers 3, 15, 75, 375...
r = 15/3 = 75/15 = 5
a = 3
Substitute the given parameters into the formula to have:
[tex]T_n = ar^{n-1}\\T_n=3(5)^{n-1}[/tex]
Hence the explicit formula for the geometric sequence is [tex]T_n = 3(5)^{n-1}[/tex]

Three pairs of faces, 3×4, 4×5, 3×5, so area
SA = 2(3×4 + 4×5 + 3×5) = 94 sq ft
V = L×W×H = 3×4×5 = 60 cubic ft
Answer: D. SA 94 sq ft, V 60 cu ft
2. Right triangular prism, base legs 3x4, height 7
Two triangular faces, combined area 2×(1/2)×3×4=12, and three rectangular faces, 3x7, 4x7 and 5x7
