Convert any mixed numbers to fractions.
Then your initial equation becomes:
7/2÷13/5
Applying the fractions formula for division,=7×5
2×13
=35/26
Simplifying 35/26, the answer is...35/26=1 9/26
Answer:
1 [tex]\frac{9}{26}[/tex]
Step-by-step explanation:
Given
3 [tex]\frac{1}{2}[/tex] ÷ 2 [tex]\frac{3}{5}[/tex] ← change mixed numbers to improper fractions
= [tex]\frac{7}{2}[/tex] ÷ [tex]\frac{13}{5}[/tex]
To perform the division
Leave the first fraction, change division to multiplication and turn the second fraction upside down.
= [tex]\frac{7}{2}[/tex] × [tex]\frac{5}{13}[/tex] ← multiply numerators/ denominators together
= [tex]\frac{35}{26}[/tex]
= 1 [tex]\frac{9}{26}[/tex]

If the area of the rectangle to be drawn is 20 square units, where should points B and D be located if they lie to the right of points A and C?
The question is incomplete. Here is the complete question.
If the area of the rectangle to be drawn is 20 square units, where should points B and D be located if they lie to the right of points A and C?
B(1, 3) and D(1, −2)
B(3, 3) and D(3, −2)
B(2, 3) and D(2, −2)
B(1, 2) and D(1, −3)
Answer: B(1, 3) and D(1, -2)
Step-by-step explanation: Area of a rectangle is the multiplication of its width and its length.
The rectangle to be has length, or distance from point A to point C, of 5 units.
For the area to be 20, width has to be 4.
Point B will be 4 units to the right of point A, which means:
[tex]x_{B}=x_{A}+4[/tex]
Point A has coordinates ( -3, 3), then:
[tex]x_{B}=-3+4[/tex]
[tex]x_{B}=1[/tex]
Because the points is "moved" to the right, instead of up or down, y-coordinate stays the same:
[tex]y_{B}=y_{A}[/tex]
[tex]y_{B}=3[/tex]
Point D will be 4 units to the right of point C:
[tex]x_{D}=x_{C}+4[/tex]
Coordinates of point C are ( -3, -2):
[tex]x_{D}=-3+4[/tex]
[tex]x_{D}=1[/tex]
Because a rectangle has a pair of sides parallel to each other, D's y-coordinate will also be the same:
[tex]y_{D}=y_{C}[/tex]
[tex]y_{D}=-2[/tex]
Coordinates of points B and D that makes rectangle ABCD have area of 20 square units are (1, 3) and (1, -2), respectively.

Answer:
a. S = 3n + 2
b. There while be 62 squares.
Step-by-step explanation:
We know the first term of this sequence is 5. To figure out the equation, subtract the following term from the previous. Do you see a common difference?
8 - 5 = 3
11 - 8 = 3
14 - 11 = 3
We're seeing a constant difference of 3 (which makes this an arithmetic sequence), but the first term is 5. That mean something is being added to make the first term 5. Subtract 3 from 5 to get 2. This means 2 is being added to every multiple of 3, which leads us to the equation: S = 3n + 2.
To find the 20th term of this sequence, substitute n for 20 and do the operations.
S = 3(20) + 2
Multiply 3 by 20, then add 2.
S = 62
The 20th term will have 62 squares.

Evaluate the expression when a=−15 and b=−5.
hat would -
A divided by b = ?
be?
Answer:
3Step-by-step explanation:
Given the following values a=−15 and b=−5.
We are to find a/b
a/b = -15/-5
a/b = 15/3
a/b = 5*3/5*1
a/b = 5/5 * 3
a/b = 1*3
a/b = 3
Hence a divided b will be 3

Find the area of the circle. Use 3.14 or 22/7 for pi. Round your answer to the nearest hundredth, if necessary.
Step-by-step explanation:
Given
diameter (d) = 9 ft
radius (r) = 9/2 = 4.5 ft
Area of the circle
= πr²
= 3.14 * ( 4.5) ²
= 3.14 * 20.25
= 63.585
= 63.59 ft

40 is 8% of what number?
Answer:
500
Step-by-step explanation:
40×100÷8=500
Number 40 is 8 percent of 500.
What is the percentage?The percentage refers to a number that is out of 100. When describing components of a whole in mathematics, percentages are employed similarly to fractions and decimals. When employing percentages, the idea is that there are 100 equal pieces that make up the whole. In addition to the shorthand "pct," which is used less frequently, the symbol "%" is used to indicate that a number is a percentage.
Let the unknown number be "x" whose 8% is 40.
Hence,
8% of x = 40
1% of x = 40/8 = 5
Thus, the value of x = 500
Therefore, 8 percent of 500 if 40.

Write a rule for the linear function shown in the graph.
A. y = 2x - 2
B. y = -2x + 2
C. y = 1/2x - 2
D. y = -x + 2
Answer:
The answer is A (y = 2x - 2)
Step-by-step explanation:
B and D aren't correct because the y-intercept is a positive 2 instead of negative 2 like the graph shown. We're now left with A and C. Go on one point of the graph and count up or down to go on the same y value as the other point. Go left or right and count until you go to the same point. Remember that the slope equation is rise/run. Rise meaning up or down. Run meaning left or right.

HELP! WILL GIVE BRAINLY!!! Find the volume of a cylinder with height = 10ft and the diameter of the base circle is 12ft.
Answer:
About 1,130.4 Cubic Feet
(My previous answer was a mistake. It has now been corrected)
Step-by-step explanation:
The Volume of a cylinder = Height * Pi * Radius^2
The radius is half the diameter, so 12 ÷ 2 = 6
Pi rounded to the hundredth place is 3.14.
Volume = 10 * 3.14 * 6^2 = 1,130.4
Therefore the Volume is about 1,130.4 cubic feet.
Answer:
Exact Volume = 360pi cubic feet
Approximate Volume = 1130.4 cubic feet
The approximate volume is found when you use pi = 3.14; use more decimal digits of pi to get a more accurate value.
===========================================================
Explanation:
The volume of a cylinder is found by the formula
V = pi*r^2*h
where,
pi = 3.14 approximatelyr = radius = 6 ft, since the radius is half the diameter.h = height = 10 ftSo,
V = pi*r^2*h
V = pi*6^2*10
V = pi*36*10
V = pi*360
V = 360pi ........... exact volume in terms of pi
V = 360*3.14
V = 1130.4 ......... approximate volume if you use pi = 3.14
The units of the volume are in "cubic feet" which we can abbreviate to "ft^3". Think of a 1 ft by 1 ft by 1 ft cube. The volume would be 1*1*1 = 1 cubic foot. So basically having a volume of roughly 1130 cubic feet means we need this many cubic blocks to form the cylinder (some of the blocks will be cut up to be able to fit).
