Triangle ABC is isosceles. What is the measure of angle C?
A. 25°
B. 30°
C. 60°
D. 75°
The answer is D, 75°.
All the interior angles of a triangle add up to 180°. With this information, we can set up this equation:
(x + 5) + (3x) + (3x) = 180
Combine like terms.
(x + 5) + (3x) + (3x) = 180
7x + 5 = 180
-5 -5
7x = 175
/7 /7
x = 25
Now, since this is an isosceles triangle, we can easily substitute the value of x into 3x. 3 • 25 = 75 which is 75°.

Pam makes 5 litters of apple juice she saves 0.5 litter of apple for dinner and puts the rest in bottles. If each bottle holds 0.75 liter how many apples of apple juice can pam fill?
Answer:
6
Step-by-step explanation:
5L - 0.5 = 4.5
Pam is putting 4.5L into bottles
4.5/0.75 = 6
0.75L = 1 bottle
x2
1.5L = 2 bottles

4.5L = 6 bottles
The graph below represents the function f(x) and the translated function g(x) .
If f(x) = x ^ 2 , which of the following functions could be an algebraic representation of g(x) ?
Answer: D. [tex]g(x) = (x-b)^2[/tex]
Explanation:
If we want to shift the curve some distance b to the right, then we'll need to replace x with x-b. What this effectively does is shift the xy axis itself b units to the left while the curve is fixed in place. This gives the illusion of the curve moving b units to the right.
Put another way: the old input x is updated to the new input x-b which is smaller by b units. This helps explain why the xy axis is shifted to the left this amount.
So that's how we go from [tex]f(x) = x^2[/tex] to [tex]g(x) = (x-b)^2[/tex]. You can think of it as [tex]g(x) = f(x-b) = (x-b)^2[/tex]

If you roll a die twice , what is the probability that sum of the two die 8 will appear
Answer:
5/36
Step-by-step explanation:
Answer:
the probability of getting a total greater than 8 is 10/36=5/18
Step-by-step explanation:
Of the 36 different possible results of rolling a die twice, 10 of them have a total greater than 8.
Therefore, the probability of getting a total greater than 8 is 10/36 which equals 5/18
Henry is investing at a continuously compounded annual interest rate of 4.4%. How many years will it take for the balance to triple? Round your answer up to the nearest whole number, and do not include units in your answer.
The number of years it would take the amount to triple is 25 years.
The formula that would be used to determine the number of years it would take the balance to triple is:
FV = PV x [tex]e^{r}[/tex]N
Where:
n = number of years fv = future value PV = present value e = 2.7182818 r = interest rate3 = [tex]e^{0.044}[/tex]N
Take the log of both sides
log(3) / log(e) / (0.044) = 25 years

Mia, jade, and Amelia sell car wash tickets. Jade sells 8 more tickets then Mia. Amelia sells twice as many tickets as Mia. The friends sell a total of 296 tickets. How many tickets does each friend sell?
Answer:
Mia sold 72 tickets, Jade sold 80 tickets, and Amelia sold 144 tickets.
Step-by-step explanation:
You can solve this question by coming up with equations for each friend and then substituting them into the equation M + J + A = 296
Jade sells 8 more tickets than Mia, so Jade's equation for how many tickets she sold is the amount of tickets that Mia sold + 8:
J = M + 8
Amelia sells twice as many tickets as Mia, so her equation is the amount of tickets Mia sold * 2:
A = 2 * M
Now we can substitute these equations into the overall one.
M + (M + 8) + (2M) = 296
Now we can combine like terms and solve for M.
2M + 8 + 2M = 296
4M + 8 = 296
4M = 288
M = 72
We now have the amount of tickets Mia sold, so we can insert this number into the equations for Amelia and Jade.
J = M + 8
J = 72 + 8
J = 80
A = M * 2
A = 72 * 2
A = 144
So Mia sold 72 tickets, Jade sold 80 tickets, and Amelia sold 144 tickets.
The solution is Mia sold 72 tickets, Jade sold 80 tickets, and Amelia sold 144 tickets
What is Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of tickets sold by Mia , Jade and Amelia be M , J and A respectively
Total number of tickets = 296
So , M + J + A = 296 be equation (1)
Now , Jade sells 8 more tickets then Mia
So , J = M + 8 be equation (2)
Subtracting 8 on both sides , we get
M = J - 8 equation (3)
Now , Amelia sells twice as many tickets as Mia
So , A = 2M be equation (4)
Substituting the value of J and A in equation (1) , we get
M + ( M + 8 ) + 2 M = 296
4M + 8 = 296
Subtracting 8 from both sides , we get
4M = 288
Divide by 4 on both sides , we get
M = 72
The number of tickets sold by Mia = 72
Substituting the value of M in equation (2) and equation (4) , we get
J = M + 8
J = 80
The number of tickets sold by Jade = 80
A = 2M
A = 144
The number of tickets sold by Amelia = 144
Hence , The number of tickets sold by Mia is 72 tickets, Jade is 80 tickets, and Amelia is 144 tickets

How many litres of water can the cylinder hold??
Answer:
1.386 litres of water can the cylinder hold.
Step-by-step explanation:
For a given Cylinder
Given:radius (r) = 7 cm
height (h) = 9 cm
π = 22/7
Now,
Volume of the Cylinder
V = πr²h
V = 22/7 × 7 × 7 × 9 cm
V = 22 × 7 × 9 cm
V = 2 × 11 × 63 cm
V = 2 × 693 cm
V = 1386 cm³
Now, Divide 1386 by 1000
1386/1000 = 1.386 litre water
Thus, 1.386 litres of water can the cylinder hold.
