Answer:
6 inches
Step-by-step explanation:
There are 12 inches in 1 foot so
12 inches X 4 feet = 48 inches
Then we subtract the 48 in minutes the 42 in to find the difference between Noelle and Oliver's height
48-42=6
Your friend wants to sell painted rocks. He spends $10.00 on startup costs, and each painted rock costs him $0.75 to make. A store offers to pay your friend's startup costs and buy his painted rocks for $0.75 each. How many painted rocks does your friend need to sell to make a profit?
1 rock
10 rocks
14 rocks
Your friend will never make a profit.
Answer:
10 rocks
Step-by-step explanation:
The cost on startup is $10 and each painted rock cost around $0.75 to make. A store pays startup cost and buy painted rocks for $0.75 each there no profit because the cost price and selling price is the same.

needed for the support wires?
Answer:34.93
Step-by-step explanation:
Using a^2+b^2=c^2we can substitute a and b in which is 34^2+8^2=c^21156+64=c^21220 = c^2Now we need to square both sides√1220 = √c^234.9284983931 ----> 34.9334.93 = cc = 34.93
Devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid. Each side of the base of the pyramid. Each side of the base of the pyramid is 9 cm and the height of the pyramid is 10 cm. To get the wax for the candle, Devin melts cubes of wax that are each 4cm by 4 cm by 4 cm. How many of the wax cubes will Devin need in order to make the candle? Show Your Work. ( Will Mark Brainliest if answered correctly and Honestly).
Answer:
5
Step-by-step explanation:
Pyramid
[tex]\textsf{volume of a square based pyramid} =\frac{1}{3} a^2h[/tex]
(where [tex]a[/tex] = base edge, and [tex]h[/tex] = height)
Given:
base edge = 9 cmheight = 10cm[tex]\implies \textsf{volume} =\frac{1}{3} \times 9^2\times10=270 \ \mathsf{cm^3}[/tex]
Wax cubes
volume of a cube = w³, where w is the length of one edge
⇒ volume = 4³ = 4 x 4 x 4 = 64 cm³
Solution
To calculate how many wax cubes are needed, divide the volume of the pyramid by the volume of a wax cube:
⇒ 270 ÷ 64 = 4.21875
⇒ 5 wax cubes are needed to make the candle
We need to round this up to 5, since we need to know the number of whole wax cubes. (If we rounded down to 4, there would not be quite enough to fill the pyramid as 4 x 64 = 256 < 270)
Find the exponential function that contains the points (2,40) and (3,8).
Answer:
Moving from point A (2,40) to point B (3,8) , you move 32 units down and one unit right, meaning your slope is 32x.
Your y-intercept is 104.
Altogether, your function (in y = mx + b format) will look like this:
y = -32x + 104

The elevator of a hotel has a maxirnurn weight capacity of 2,000 pounds. If there are 3 people on the elevator that have a combined weight of 460 pounds, write AND SOLVE an inequality expressing the possible weights that may be added to the elevator, Use "W" to represent weight.
Answer:
W=460+460+460
W=1380
2000≠1380
2000-1380=620
2000=1380+620

what does 118=k+70 answer?
[tex]118 = k + 70 \\ 118 - 70 = k \\ 48 = k[/tex]
Answer: 48
Step-by-step explanation:
You do opposite operations, so instead of adding 70, you subtract subtract it- 118-70=k+70-70. You do it to both sides to keep the equation balanced. Simplify to get 48=k.

The answer is -15.75 because 4= -16= -79 you have to turn 16 positive so add 16 to -79 to get -63 then divide by 4 to get the answer -15.75.
Find the location of Boston as an ordered pair
I need help please. its hard..
hello againn
okay, so lets see how 32 can become 20. We can subtract 12, so that is possible. Lets check with our other inputs.
if all inputs - 12 = the output, that is the function.
14 - 12 = 2. 2 is our output, so that is a very good sign.
We cant check the third one, so lets skip that for now.
-2 - 12 = -14, which is our output. (yay!!!)
And we cant fill in the last one, which is okay.
So now we know our function is y = x - 12.
Now we fill in the question marks.
The third one. -6 + 12 = 6. The input for 3. is 6.
Last one, 10 - 12 = -22.
Function: y = x-12
Fill ins, third = 6
Last = -22.
:D!!!
Find the distance between the points (6, 4) and (10, 7).
Answer:
5 units
Step-by-step explanation:
Use the distance formula [tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2[/tex] where [tex]d[/tex] is the distance between points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex].
Given that [tex](x_1,y_1)\rightarrow(6,4)[/tex] and [tex](x_2,y_2)\rightarrow(10,7)[/tex], then:
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\\\d=\sqrt{(7-4)^2+(10-6)^2}\\\\d=\sqrt{3^2+4^2}\\\\d=\sqrt{9+16}\\\\d=\sqrt{25}\\\\d=5[/tex]
This means that the distance between (6,4) and (10,7) is 5 units

A hot-air balloon, headed due east at an average speed of 30 miles per hour at a constant altitude of 95 feet, passes over an intersection (see the figure). Find an expression for its distance d (measured in feet) from the intersection t seconds later.
Step-by-step explanation:
1 mile = 5280 ft
1 hour = 3600 seconds (60 minutes of 60 seconds each).
the open question here is : do we need the ground distance, or really the line of sight distance (e.g. directly above the intersection the distance is 0 ft ground distance but 95ft line of sight distance) ?
based on the above conversions the speed
30 miles per hour = 30×5280 ft per 3600 seconds =
= 158,400 ft / 3600 s = 44 ft/s
so, the balloon moves away from the intersection 44 ft every second.
so, just for ground distance in ft we would have
d = 44t
for the line of sight distance we need to use Pythagoras, as we need to calculate the length of the Hypotenuse (= the line of sight) of the right-angled triangle of ground distance, height and line of sight.
the ground distance is again the same function as before (44t). height is constant (95 ft).
so,
d² = (44t)² + 95² = 1936t² + 9025
d = sqrt(1936t² + 9025)
so, e.g. after 1 second the line of sight distance would be
d = sqrt(1936×1 + 9025) = sqrt(1936 + 9025) =
= sqrt(10961) = 104.6947945... ft
that means although the ground distance increased by 44 ft, the line of sight distance increased only by roughly 10 ft.
that's how right-angled triangles work.
after 2 seconds d = 129.4951737... ft, so, roughly a 25 ft increase compared to 1 second. the change rate of the line of sight distance (the Hypotenuse) will get closer and closer to the (constant) change rate of the ground distance (but will never fully reach it - only in infinity ...).
Kunio puts $2,200.00 into savings bonds that pay a simple interest rate of 2.4%. How much money will the
bonds be worth at the end of 4 years?
O $4,734.40
O $2,387.25
O $2,411.20
O $211.20
Answer:
$2,411.20
Step-by-step explanation:
Use the simple interest formula: A = P(1 + rt)
A = Final amount (?)
P = Starting amount (2200)
r = Rate (0.024)
t = Time in years (4)
A = 2200(1 + 0.024 · 4)
A = 2200(1.096)
A = 2411.2

What’s the correct answer for this question?
Answer: 2295 ft ^2, 255 yd^2
Step-by-step explanation:
The area of the field is the length times the width.
Since there are 3 feet in 1 yard, 15 yards = 45 feet.
So the area in square feet = 45*51 feet^2 = 2295 ft ^2
Since there are 1/3 yard in 1 feet, 51 feet = 17 yards
So the area in square yards = 15*17 yard^2 = 255 yd^2

Answer:
the period of this graph is 2[tex]\pi[/tex]
Step-by-step explanation:
The period is the length of the section that repeats. So for this graph, we need to calculate the distance between 2 peaks or 2 troughs of the curve.
Let's look at the peaks (maximums).
One is at x = 0 and the next is at x = 2[tex]\pi[/tex]
2[tex]\pi[/tex] - 0 = 2[tex]\pi[/tex]
Therefore, the period of this graph is 2[tex]\pi[/tex]

Answer:
the answer is D.meet state regulations
The following is not a valid reason for a dealership to offer incentives is Meet state regulations.
What is Dealership Incentive?Manufacturers utilise dealer incentives as a financial tactic to encourage dealers to sell their goods by providing price reductions on those goods. Dealer incentives might come in the form of a lower purchase price for the dealer, a cash payment, or a financial incentive, such a consumer refund.
A moving inventory list is a document that lists every item you'll be transporting from your current location to your new one.
A quota is a predetermined number of sales or other tasks that you must do within a specific time frame.
