Answer: The opposite sides in a rectangle are equal.
Step-by-step explanation:
If all sides were equal, you would have a square.
If the opposite sides were not parallel, you would not have 4 sides that meet at 90 degrees.
All angles in a rectangle are 90 degrees.
The opposite sides in a rectangle are equal. The statement is true. Then the correct option is C.
What is a quadrilateral?The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.
Let's check all the options.
A. All the sides in a rectangle are equal. The statement is false because opposite sides are equal.
B. The sides in a rectangle are not parallel. The statement is false because opposite sides are parallel.
C. The opposite sides in a rectangle are equal. The statement is true.
D. The angles in a rectangle are all different. The statement is false because all angles are equal.
The opposite sides in a rectangle are equal. The statement is true. Then the correct option is C.

A logger cuts down a tall tree while thinning a stand of longleaf pine trees. He cuts the tree trunk into several roughly cylindrical logs that can be carried. One log from near the top of the tree measures 32 inches around its circumference and 42 inches long. Another log cut from the lower part of the tree measures 64 inches around its circumference. If both logs have the same volume, about how long is the log cut from the lower part of the tree trunk?
A 7 inches
B 10.5 inches
C 14 inches
D 21 inches
Answer:
14
Step-by-step explanation:
Divide 64 by 28.26. Then you get 2.2. Then multiply it by 64.

Answer:
40°
Step-by-step explanation:
65° + 75° = 140°
180° - 140° = 40°
Further explanation:
You add 65° and 75° you get 140°.
All triangles must equal 180°, you subtract 140° from 180° and that equals 40°.

You deposit $400 in an account. The account earns $18 simple interest in 9 months.What is the annual interest rate?
Use the formula,
I = Prt
P = Principal amount = 400
I = interest = 18
r = annual rate
t = time in years = 9/12 = 3/4
so,
18 = 400*r*3/4
r = 0.06
so the annual interest rate is 0.06 or 6%
Three sodas and four hotdogs costs $15. Two sodas and a hotdog costs $5. How much does seven hotdogs cost?
Answer:
$26.25
Step-by-step explanation:
I'm not completely sure if I did this right because I haven't used this in a while, but let's say sodas are x and hot dogs are y. The first equation would be 3x+4y=15 and in order to solve for x or y you have isolate them to seperate sides because if there is not letter on the other side, it will just end up being zero... if that makes sense. subtract 3x so the equation is now 4y=15-3x and divide everything by 4, to make the equation y=3.75-3/4x. Do the same thing but subracting the 4y and dividing by 3 to get the x value. Now we're left with y=-3/4+3.75 and x=5-4/3y (or x=5-1 1/3y). remember that x=sodas and y=hotdogs. The equation we need to create has seven hot dogs and no sodas, so we simply need to take the equation for y and substitute y for 7 because we have 7 hot dogs and y is the symbol used for hot dogs. This equation would now be 7(-3/4x+3.75) because hotdog=y=-3/4x+3.75, so hotdog=-3/4+3.75 and we have 7 hot dogs so you just multiply that by 7

Suppose f(x) = abx + c is an exponential function. One value which b CANNOT have is
Answer:
b cannot be 1
Step-by-step explanation:
Given
[tex]y = ab^x + c[/tex]
Required
Values b cannot have
In an exponential equation, the value of b can be:
[tex]b > 1[/tex] ---> This represents growth
[tex]b < 1[/tex]----> This represents decay
[tex]b \ne 1[/tex] ---> The value of b can't be 1. If b is 1, then it is not an exponential function
Principal = $800
Interest Rate = 3.5%
Time = 6 months
Find the interest earned.
Answer:
Step-by-step explanation:
principal 800 multiply by 3.5 percent
2800 is the interest multiplied by 6 months
=16800/ 168.00
Based on the information given the interest earned is $14.
Using this formula
Interest=Principal ×Rate × Time
Where:
Principal=$800
Rate=3.5% or 0.035
Time=6/12
Let plug in the formula
Interest earned=$800×0.035×6/12
Interest earned=$14
