A cat can travel a distance of 32.5 meters in 13 seconds. What is the average speed of the cat to the nearest hundredth of a m/s? *
A 2.5 mph
B 0.4 mph
C 2.5 m/s
D 0.4 m/s
Answer:
C. 2.5 m/s
Explanation:
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
[tex]Speed = \frac{distance}{time}[/tex]
[tex]S = \frac{d}{t}[/tex]
Given the following data;
Distance = 32.5m
Time = 13secs
Substituting into the above equation;
[tex]S = \frac{32.5}{13}[/tex]
Speed, S = 2.5m/s

Tom went to purchase a new video game. The original price was $60, but it is his lucky day, and it is on sale for $32. What percent is the original price marked down? 18.75% 87.5% 46.67% 53.33%
Answer:
46.67%
Step-by-step explanation:
60÷100=0.60 , 1%=0.60 , 0.1%=0.06 , 0.01%=0.006
60-32=28
28÷0.6=46 46%=27.6 , 0.67%=0.4 27.6+0.4=28 46+0.67=46.67%

Jon filled a bucket with 2.7 gallons of water. He used 0.98 gallons for watering his tomato plants and 0.76 gallons for watering his peppers. How much water did he have left in his bucket?
Answer: quantity of water left over = 0.96 gallons
Step-by-step explanation:
Given: Total quantity of water = 2.7 gallons
Water used for tomato plants = 0.98 gallons
Water used for peppers = 0.76 gallons
Total water used = 0.98 +0.76 = 1.74 gallons
Then, quantity of water left over = Total quantity of water - Total water used
= 2.7 - 1.74 gallons
= 0.96 gallons
Hence, quantity of water left over = 0.96 gallons

ΔABC is reflected across a horizontal line through (0, 2). Which property changes?
Answer:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed).

Find the value of y for which the value of 8y+3 is 7 more than the value of 6yTom and Sam can finish a plowing job in two hours if they work toghether. Tom working alone can do the job in 7 hours. How long would it take Sam to finish the same job alone?
Answer:
19 ; 2.8 hours
Step-by-step explanation:
Find the value of y for which the value of 8y+3 is 7 more than the value of 6y
8y + 3 = 7 + 6y
8y - 6y = 7 - 4
2y = 3
y = 3/2
y = 1.5
Let
Tom's rate = x
Sam's rate = y
Rate = 1 / time
Hence,
x = 1/7
Rate when they work together = 1/2
Tom's rate + Sam's rate = 1/2
1/7 + y = 1/2
y = 1/2 - 1/7
y = (7 - 2) / 14
y = 5/14
Since, rate = 1/time
Time = 1/ rate
Sam's time = 1/ rate = 1/y = reciprocal of y
Sam's time = 14/5 = 2.8 hours
2.8 hours = 2 hours (0.8 * 60) = 2 hours 48 minutes
3. Olivia ordered 24 cupcakes and a layer cake. The layer cake cost $16 more than one
cupcake, and the total cost of the order was $53.50. What was the price of each cupcake?
Answer:
$1.50
Step-by-step explanation:
The total cost was $52. Subtracting out the cost of the layer cake ($16) leaves us with $36 to pay for the 24 cupcakes.
This means that each cupcake must have cost $1.50 ( = $36 / 24 cupcakes )

An angle measures 125.2° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
27.4 and 152.6
Step-by-step explanation:
Supplementary angles equal 180 degrees when placed together.
x+(x+125.2)=180
2x+125.2=180
2x=54.8
x=27.4
the angles are 27.4 and 152.6
