A car travels 360 miles in 8 hours (with a constant speed). How much time will it take traveling 168 miles?
Answer:
3.7hours
Step-by-step explanation:
Step one:
A car travels 360 miles in 8 hours
the speed is calculated as
speed= distance/time
speed= 360/8
speed= 45mph
Step two:
How much time will it take traveling 168 miles?
having found the speed, which is the rate at which the car is tavelling
time= distance/speed
time= 168/45
time= 3.7hours
A quantity with an initial value of 970 grows exponentially at a rate of 3.5% every 3 weeks. What is the value of the quantity after 49 days, to the nearest hundredth?
Answer:
≈1051.07
Step-by-step explanation:
Answer: 1091.8
Step-by-step explanation:
if you need the equations to go with it it SHOULD be
f(x) = 970(1+0.052) ^ 21/49
what changes in a wave to make a sound high pitch or low pitch?
Answer:
Volume is dependent on how hard the air is pushed through. Sound travels more slowly than light. Sound waves travel at the same speed, but vibrate in different ways. Some vibrate quickly and have a high frequency or pitch, while others vibrate slowly and give a lower pitch.

Step-by-step explanation:
Select the ordered pair that is a solution of the system of linear equations.
y = 4x - 7
y = -x +3
o (1,2)
o (2,1)
o (1,1)
o (2,2)
Answer:
the ordered pair will be (1, 2)
Step-by-step explanation:
first of all substitute the x and y values into the equation in other to make the equation true.
Therefore y=4x-7
1 = 4(2) -7
1 = 8 -7
1 = 1
Making the first equation true. then move to the second equation which is y = - x + 3
1 = -(2) + 3
1 = 1

Find LN.
A. 38
B. 56
C. 58
D. 76
Answer:
B. 56°
Step-by-step explanation:
[tex] 20 \degree = \frac{1}{2} (96 \degree - \widehat{LN}) \\ \\ 2 \times 20 \degree = (96 \degree - \widehat{LN}) \\ \\ 40 \degree = (96 \degree - \widehat{LN }) \\ \\ \widehat{ln} = 96 \degree - 40 \degree \\ \\ \huge \red{ \widehat{LN} = 56 \degree}[/tex]

Midpoint of (-6, 3) and (8, -7)
Answer:
Midpoint of (-6, 3) and (8, -7) is: (1, -2)
Step-by-step explanation:
Given the points
(-6, 3)(8, -7)Computing the midpoint of (-6, 3) and (8, -7) using the formula
⇒ [tex]\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-6,\:3\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)[/tex]
⇒ [tex]\left(\frac{8-6}{2},\:\frac{-7+3}{2}\right)[/tex]
⇒ [tex]\left(1,\:-2\right)[/tex]
Therefore, Midpoint of (-6, 3) and (8, -7) is: (1, -2)

Caitlin has a $10 gift certificate to the music store. She has chosen a number of CDs from the $7 bargain bin. If the cost of the CDs is $32 after the gift certificate is credited, which equation could be used to determine how many CDs did Caitlin buy?
Answer:
32+10=7x
Step-by-step explanation:
Let's solve this first. 32$ is the final price, and then add 10$ because of the gift card, leaving you with 42$. Divide the 42 by 7, because each CD is 7 dollars. The result is 6. So put that into an equation.
32+10=42=7x
x=6!
