Answer:
9 = x (assuming 15 is the hypotenuse)
Step-by-step explanation:
15^2 = 12^2 + x^2
225 = 144 + x^2
subtract 144 from both sides
81 = x^2
square root both sides
9 = x
name the property that justifies each statement -3(m+8)=-3m-24
Answer: Distributive Property
Explanation: The distributive property tells us that if we're given an expression such as -3(m + 8), we can multiply the -3 by both the m and the 8.
what is the answer to y+5<9
Answer:
I think the answer would be y<4
Please help I’m struggling
Answer:
x = -4
Step-by-step explanation:
x= 3 is a parallel to y axis. So a parallel line to x = 3 must be parallel to y axis.
A line parallel to y axis has a generic equation: x = h. We know that the line passes to the point with has x coordinate = -4
So the equation is x= -4
If the triangle below is enlarged by a scale factor of 1.2, what will be the area of the new triangle?
Answer:
Step-by-step explanation:
A=bh/2
A=(1.2b)(1.2h)/2
A=1.44(bh)/2
A=0.72bh
b=10cm and h=5c
A=0.72(10)(5)
A=36 cm^2
Answer:
36cm sqaured
Step-by-step explanation:
Step-by-step explanation:
A=bh/2
A=(1.2b)(1.2h)/2
A=1.44(bh)/2
A=0.72bh
b=10cm and h=5c
A=0.72(10)(5)
A=36 cm^2
5. How much force is needed to stop a 1,400 kg truck pulling up to a stop light if
the truck took 4 seconds to stop and was moving at 36 m/s?
Answer:
Step-by-step explanation:
F=ma
F=m(dv/dt)
F=1400(-36/4)
F=-12600N (the negative sign just means the force was slowing the vehicle, the magnitude of the force is just the absolute value.
F=12600N

s=96
So there were 96 students.
True or false?is the point(16,4) included in this function: Y=2x or Y=x2 or y= x+12 or y=x-12
Answer:
True
Step-by-step explanation:
It is true because the graph of [tex]y=x-12[/tex] passes through the point [tex](16,4)[/tex]
x = 16
y = 4
Substitute
4 = 16 - 12
4 = 4
Therefore, the answer is true.

Answer:
2.1134 liters
Step-by-step explanation:
There are 4 quarts in a gallon and each quart is 1.0567 liters. 2 quarts are 1/2 a gallon. 1.0567*2=2.1134
9514 1404 393
Answer:
2. 1.8927 L
3. 603.22 cm²
Step-by-step explanation:
To convert units, multiply by a ratio whose value is 1. That is, the numerator and denominator are equal amounts, but have units that cancel ones you don't want and give you units you do want.
2.
[tex]\displaystyle \frac{1}{2}\text{ gal}\times\frac{4\text{ qt}}{1\text{ gal}}\times\frac{1\text{ L}}{1.0567\text{ qt}}=\frac{4}{2\times1.0567}\text{ L}\approx\boxed{1.8927\text{ L}}[/tex]
__
3.
[tex]A=LW=(8.5\text{ in})(11\text{ in})\times\left(\dfrac{2.54\text{ cm}}{1\text{ in}}\right)^2=\boxed{603.2246\text{ cm}^2}[/tex]
_____
Additional comment
It can be helpful to remember that a liter is larger than a quart. So 2 quarts will be less than 2 liters. (You may recall reading on the half-gallon container that it holds 1.89 L.)

Solve for x using cross multiplication 3x - 3 5 = 2x – 2 4 x = [?]
Answer:
x = -35/22, or 1.5909090...
Step-by-step explanation:
Solving for x will be easy enough, but cross multiplication won't be necessary as that's only applicable when division is involved:
35 = 2x - 24x
35 = -22x
x = -35/22, or 1.5909090...

Answer:
45
Step-by-step explanation:
hello there!
Remember all of the angles in a triangle will add up to equal 180 so to find the missing angle we subtract the given angles from 180
180 - 90 - 45 = 45 so the missing angle would equal 45
please do explain how u got it
Answer:
$3
Step-by-step explanation:
cost of tank tops
20 / 5 = $4 each
cost of t-shirts
35 / 5 = $7 each
7 - 4 = $3
Answer:
$3
Step-by-step explanation:
1.Approach
To solve this problem, one must first find the cost of each product. This can be done by diving the price by the amount of each product. After finding the unit price of each product, one will subtract the cost of the tank-top from the cost of the t-shirt.
2.The unit price of a t-shirt
It is the given that 5 t-shirts cost $35. Divide the price of the shirts by the number of shirts to find the cost of each individual shirt.
35 ÷ 5 = 7
Each individual t-shirt costs $7.
3.The unit price of a tank-top
It is given that 5 tank-tops cost $20. Divide the price of the tank-tops by the number of tank-tops to fund the unit price of each tank-top.
20 ÷ 5 = 4
Each tank-top costs $4.
4.Find out how much more each shirt costs
Now subtract the price of the unit price of the tank-top from the unit price of the t-shirt.
(t-shirt) - (tank-top)
= 7 - 4
= 3

A pair of Sneakers cost $112 after it was marked up by 75%. How much
did it cost before the mark up?
Question
A pair of Sneakers cost $112 after it was marked up by 75%. How much
did it cost before the mark-up?
Answer
Divide the gross profit by the cost and multiply by 100 to calculate your percentage markup. In the example, divide $75 by $100 which equals $0.75, and multiply by 100 to give you 75 percent. Your markup on cost price is 75 percent.
Therefore, the answer would be (196)
Answer:
i believe the answer would be $448
Step-by-step explanation:
hopefully this helps :)
have a nice day !!
