A car increases, then decreases, its speed. Which table could represent the speed of the car?
A. A 2-column table with 5 rows. The first column is labeled time (minutes) with entries 5, 6, 7, 8, 9. The second column is labeled speed (miles per hour) with entries 45, 43, 41, 42, 43.
B. A 2-column table with 5 rows. The first column is labeled time (minutes) with entries 5, 6, 7, 8, 9. The second column is labeled speed (miles per hour) with entries 45, 47, 49, 48, 47.
C. A 2-column table with 5 rows. The first column is labeled time (minutes) with entries 5, 6, 7, 8, 9. The second column is labeled speed (miles per hour) with entries 45, 45, 45, 43, 41.
D. A 2-column table with 5 rows. The first column is labeled time (minutes) with entries 5, 6, 7, 8, 9. The second column is labeled speed (miles per hour) with entries 45, 43, 41, 41, 41.
Answer:
The speed increases (45—>47—>49) then decreases (48—>47) over time.

Are the ratios 1:3 and 4:5 equivalent?
yes or no
Answer:
No, they are not.
Remember, a ratio can be written as a fraction. So 1:3 is the same as 1/3 and 4:5 is the same as 4/5.
1/3 = 0.33
4/5 = 0.8
As you can see the both don't equal the same numbers, so they aren't equivalent.

Answer: 47.25
Step-by-step explanation:
the equation for finding the area of a triangle is base times height divided by 2
10.5(9)= 94.5
94.5/2=47.25
Answer:
47.25 sq ft is the area. no idea what you want me to do with the 4% though
Step-by-step explanation:
area for traingles = (base×hight)÷2
so your equation would he (10.5ft×9ft)÷2
10.5×9= 94.5
94.5÷2÷47.25
so the answer is 47.25 ft^2 (or simply sq ft)

Jinny is selling bracelets for $2.50. So far, she has earned $175.00. She needs to earn more than $230.00 in order to meet her goal.
How many more bracelets, x, does she need to sell in order to reach her goal? Select the inequality that includes the fewest number of bracelets that she can sell and still reach her goal.
Answer: 25
Step-by-step explanation:
she’s earned 175 so far she needs 230. So 230-175=55, so she needs 55 more dollars. 55÷2. 50(price of each bracelet) = 25
In a right triangle, one of the angles measures 37°. What is the measure of the other angle?
A. 37°
B. 43°
C. 53°
D. 87°
E. 117°
Im pretty sure the answer is C: 53° because a right triangle equals 90° and 90° - 37° = 53° but I want to double check.
Answer:
Yep, 53°
Step-by-step explanation:
Sum of angles in a triangle equals 180.
We have two angles: 90° (since it is a right angle triangle) and 37°
Therefore 180 - (90+37) = 180 - 127
Answer is 53°

3^1)x3)/3
Answer:
Here is your answer . Hope this helps.
Hi! I'm happy to help!
To solve this, we have to start inside the most parenthesis, then work our way out, then divide by 3.
We first have 3^1. There is a rule that x^1=x, so 3^1=3.
((3^1)x3)/3
(3x3)/3
Next, we have 3×3, which is 9..
9/3
Finally, we have 9/3, or 9÷3, which is 3.
3
So, our final answer is 3.

rewrite -6 - (-3) using addition
Answer:
-6+3 because you can distribute the negative sign into the parenthesis and make it a positive.
Answer:
So the answer would be -6+3
Step-by-step explanation:
Here's why:
So think of this strategy when working with these problems
Draw the line connect the sign
This means to convert the -(- into a plus sign, which makes these problems way easier
So that's why the answer is -6+3
Answer = -3

The height of a bookcase is 1.93 meters. Which expression converts this height to feet? Note: 1 foot is approximately 0.3048 meters and 1 meter is approximately 3.2808 feet.
A
1.93m×(0.3048ft1m)
B
1.93m×(3.2808ft1m)
C
1.93m×(1m0.3048ft)
D
1.93m×(1m3.2808ft)
The expression which converts the height of the bookcase to feet is 1.93 × (3.2808ft / 1m)
To make the conversion of meters to feets , we use dimensional analysis ;
We need to multiply the given measurement in meters by its appropriate or equivalent value in feets :
Recall :
1 meter = 3.2808 feets
Then the height of the bookcase in feets will be :
1.93 meters × 3.2808ft / 1m
Hence, the appropriate expression is : 1.93 meters × 3.2808ft / 1m

To solve this, we have to divide the 18 pounds, in 1/8 portions. We do this with division. To make this problem easier to solve, we need to turn it into a multiplication problem (opposite of division). To still make the problem correct, we have to take the opposite of one of our numbers. Let's take 1/8, and turn it into 8, now we have the problem:
18×8=
