Assuming that the Skateboard is $180, and you are asking for the price when it is 30% off.
180 * .70 = $126
Another way of solving the question is finding 10 % of 180, which is 18. And you are looking for 30% less, so 18 * 3 = 54, which is 30% of 180.
180 - 54 = 126

Triangle Congruency please help!!
Answer:
A
Step-by-step explanation:
the nice thing about triangle is that the smallest angle is always opposite the smallest side, etc. also, we can get the remaining angle because we have 2 angles already and there are always 180 degrees in a triangle.
50+ 63= 113
180-113 =67
so, 50 is the smallest angle and thus the side opposite of it is the smallest. next is side bc because 63 is the next biggest angle measure. lastly, side ac is the largest because it's opposite of the largest angle measure

Sally bought 4 chocolate bars and 8 lollipops and paid $8.00. Josh bought 3 chocolate bars and 10 lollipops and paid $7.00.
What is the cost of a lollipop? Enter your answer as a decimal
Answer:
Lollipops cost $0.25
Step-by-step explanation:
4C + 8L = $8.00
3C + 10L = $7.00. We need to cancel out chocolate bars
-12C - 24L = $-24.00 Mulitply by -3
12 C + 40L = $28.00 Muliply by 4 Next simplify
16L = $4.00 Divide both sides by 16
L = $0.25
WE CAN EVEN CHECK OUR WORK
4C + 8(0.25) = $8.00
4C = $6.00
C = 1.5
3(1.5) + 10(.25) = $7.00
4.5 + 2.5 = 7

Which of the following are not perfect squares? Select all that apply.
16
44
81
6
49
24
Answer and Step-by-step explanation:
44, 6, and 24 do not have perfect squares.
To be a perfect square, they have to be able to have a number that, when it multiplies itself by itself (needs to be a whole number), it turns into the bigger number.
44, 6, and 24 can't do this when being square rooted.
16 turns into 4.
81 turns into 9.
49 turns into 7.
#teamtrees #PAW (Plant And Water)
Answer:
44, 6, and 24
Step-by-step explanation:
4²=16 so it's a perfect square
9²=81 so it's a prefect square
7²=49 so it's a perfect square
44, 6, and 24 all result in decimals so it's not a perfect square.

Jada walks up to a tank of water than can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water.
a. At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.
b. How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.
c. How many minutes before Jada arrived was the water tank completely full? Explain or show your reasoning.
Answer:
a. rate to empty the tank = - 2/3 gal/min
b, 7.5 min to empty the tank
c. 4.5 min.
Step-by-step explanation:
I use the formula that the work done = rate of work times the time working = W = rt
The work in this problem is emptying the tank.
a. The rate to empty the tank is -2 gal/3 min or - 2/3 gal/min
b. 5/(2/3) = 15/2 = 7.5 min to empty the tank
c. Since 3 gal. had already drained, 3/(2/3) = 9/2 = 4.5 min.

Mackenzie invested $770 in an account paying an interest rate of 6.1% compounded
continuously. Assuming no deposits or withdrawals are made, how long would it
take, to the nearest year, for the value of the account to reach $1,830?
Answer:
14
Step-by-step explanation:
The value of the account will reach to $1,830 in 15 years.
What is compound interest?Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.
Given that, Mackenzie invested $770 in an account paying an interest rate of 6.1% compounded continuously after a certain period of time the mount becomes $1830
We know that,
[tex]A = P(1+r)^n[/tex]
Where, A = amount, P = principal, r = rate and n = time.
1830 = 770(1+0.061)ⁿ
1830 / 770 = (1.061)ⁿ
2.37 = (1.061)ⁿ
Taking log both side,
log(2.37) = n log(1.061)
n = log(2.37) / log(1.061)
n = 14.57 ≈ 15
Hence, the value of the account will reach to $1,830 in 15 years.

If a cylindrical vase has a 63 cubic centimeter volume an a cone has the same height and radius as the cylinder what is the volume of the cone
Answer:
[tex]21cm^{3}[/tex]
Step-by-step explanation:
According to the problem, calculation of given data are as follows,
Volume of cylindrical vase = [tex]63cm^{3}[/tex]
As, Cone has same height and radius as cylinder, than we can calculate volume of cone by using following formula,
Volume of cone = [tex]\frac{1}{3}[/tex] × Volume of cylindrical vase
By putting the value, we get
Volume of cone = [tex]\frac{1}{3}[/tex] × 63
Volume of cone = [tex]21cm^{3}[/tex]

Consider function f. F(x) = ^3square8x + 4
Answer:
[tex]f^{-1}(x)=\frac{1}{8}(x-4)^{3}[/tex]
Step-by-step explanation:
Given function is,
f(x) = [tex]\sqrt[3]{8x}+4[/tex]
To find the inverse of this function,
Rewrite the function as a equation,
y = [tex]\sqrt[3]{8x}+4[/tex]
Interchange x by y and y by x,
x = [tex]\sqrt[3]{8y}+4[/tex]
Now solve this equation for y,
x - 4 = [tex]\sqrt[3]{8y}[/tex]
(x - 4)³ = [tex](\sqrt[3]{8y})^3[/tex]
(x - 4)³ = 8y
y = [tex]\frac{1}{8}(x-4)^{3}[/tex]
Now convert the equation into function,
[tex]f^{-1}(x)=\frac{1}{8}(x-4)^{3}[/tex]
f(x) = x ^ 2 What is g(x)?
Answer:
A ; g(x) = (1/2 x)^2
Step-by-step explanation:
Here, we want to get g(x)
we have a point on the curve g(x)
The point is represented by (2,1)
What this mean here is that, when x = 2, y = 1
Looking at the first option;
Substitute 1 for y and 2 for x
1 = (1/2 * 2)^2
1 = 1
This means this is our answer
The equation for g(x) is;
g(x) = (1/2 x)^2
In a right triangle, one acute angle is 22º and the hypotenuse is 70 cm. Find the
lengths of the legs and the other angle measure.
Answer:
Adjacent leg (In relation to the angle that is measure 22 degrees)= 70*Cosine 22 or 64.9; Opposite leg (In relation to the angle that is measure 22 degrees)=70* Sin 22 or 26.22
Step-by-step explanation:
The other angle measure is 90-22 or 68.
To find the length of the adjacent leg (a) use cosine. Remember cosine is Adjacent leg over hypotenuse.
Cosine 22= a/70- Multiply by 70
70* Cosine 22=a or about 64.9
To find the length of the opposite leg (o) use sine. Remember sine is Opposite leg over hypotenuse
Sine 22= o/70
70*Sine 22=o
o= about 26.22

15/3 = 45/x
solve for x
Answer:
15/3=45/x
We move all terms to the left:
15/3-(45/x)=0
Domain of the equation: x)!=0
x!=0/1
x!=0
x∈R
We add all the numbers together, and all the variables
-(+45/x)+15/3=0
We add all the numbers together, and all the variables
-(+45/x)+5=0
We get rid of parentheses
-45/x+5=0
We multiply all the terms by the denominator
5*x-45=0
We add all the numbers together, and all the variables
5x-45=0
We move all terms containing x to the left, all other terms to the right
5x=45
x=45/5
x=9
