Answer:
d=80+t
Step-by-step explanation:
An equation that relates his distance travelled (d) to the time elapsed (t) is d = 80t and the time taken to travel 320 miles is 4 hours.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Joey drives his car 80 miles per hour on the highway.
For 1 hours, the distance travelled is 80 miles,
For t hours, the distance travelled will be 80t miles.
So, distance, d = 80t, which is the required equation.
When the distance is 320 miles, the time taken to travel it is,
t = d / 80
t = 320 / 80
t = 4 hours
Hence the time taken to travel 320 miles is 4 hours.

Step-by-step explanation:
We find an equation using variable [tex]N[/tex] assuming [tex]N[/tex] is in the bottom right corner.
Our equation is [tex]90+60+N=180[/tex] because the sum of the three angles is [tex]180[/tex].
Solving by subtracting both [tex]90+60[/tex] from both sides,
We have [tex]N=30[/tex] which is our solution.

If the volume of a square-based pyramid is 300 cm cubed with a height of 9 cm, then what is the height of the base?
Answer:
9.4868 cm Rounded: 9.5cm
Step-by-step explanation:
V(Volume) = 1/3 x B(Base area) x h
300 = 1/3 x B x 9
10 x 1/3 = 10,3
300/10,3 = 90
B = 90^2
l(length of the base) = [tex]\sqrt 90[/tex] = 9.4868
Rounded Answer (to the first decimal) = 9.5

Step-by-step explanation:
Answer: b = 12
Step-by-step explanation: a² +b² = c²
a² + 9² = 15²
a² + 81 = 225
a² = 225 - 81
a² = 144
√a² = √144

Which of the following expressions could be used to find the sale price of an item that costs d dollars if it is on sale for 30% off?
0.7 d
0.3 d
30 d
70 d
Answer:
0.3 d
Step-by-step explanation:
A percent is basically the percent over 100
In this case, the item is 30% off so you can write 30% as a fraction like the following:
30/100
Now we can convert that to decimal
30/100 is also 0.30
Since there is no need for the extra zero in this case
the answer for this question is:
0.3 d
Answer: 0.3d should be correct

Answer: 22ft^3
Step-by-step explanation:
First, find the volume of the little cubes that the rectangular prism can hold inside of itself.
The formula for volume of a rectangular prism is:
V = length x width x height.
= 1/2 x 1/2 x 1/2
= 1/8
Now, since the rectangular prism can hold 176 of these cubes, you need to multiply each cubes volume, 1/8, by 176. 1/8 x 176 = 22
Therefore, the volume of the box is 22ft^3

Answer:
D.
Step-by-step explanation:
The time goes up by 1 every time and the distance goes up by 500 every time. Lets lok at the relationship:
As seen in the graph, every minute she goes 500 ft. Theoretically, if we take half of the time to run then we must take half of the distance. This can be described as a distance/time relationship. So now with that knowledge, we loot at the 10-minute mark; she's currently at 5,000 feet so if she goes half the time more we are adding half the feet she runs per minute (250ft). Therefore the answer is 5,250 feet since we are adding 250(half the time she runs per minute) to 5,200 feet(how much she ran in 10 minutes)

A soda bottle holds 1.5 liters of soda. How many milliliters does the bottle hold? (4 points)
15 milliliters
150 milliliters
1,500 milliliters
15,000 milliliters
Hello!
Answer:
[tex]\Large \boxed{\sf 1.5L = 1500mL}[/tex]
Step-by-step explanation:
We want 1.5L in mL.
We have this table:
Let's put 1.5L:
kL daL hL L dL cL mL
1 . 5
Translate 1.5L into mL by moving the comma to the right until you reach mL:
kL daL hL L dL cL mL
1 5 0 0
So 1.5L = 1500mL.
