A tailor has 13 1/2 yards of fabric to use for making costumes. For each costume, he needs 1 1/2 yards of fabric for the top and 3/4 yards bottom. How many costumes can he make
Answer:
6 complete costumes
Step-by-step explanation:
he has 27/2 total fabric
1 costume requires 1 2/4 + 3/4 of fabric, which is 2 1/4
we divide 27/2 by 9/4
27/2 x 4/9 = 6
How much money needa to be deposited now into an account to obtain 9,000 in 7 years if the interest rate is 8% per year compounded continuously?
Answer:
P: the principal, the amount invested
A: the new balance
t: the time
r: the rate, (in decimal form)
Step-by-step explanation:
Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.
P = $1000, t = 2 years, r = 0.08.
A = 1000(1+0.08(2)) = 1000(1.16) = 1160

Find the value of c so that (x+3) is a factor of the polynomial p(x). p(x)=x^3-4x^2+cx+33
Answer:
The value of c is -10.
Step-by-step explanation:
Since (x+3) is a factor of the polynomial p(x).
We have that:
x + 3 = 0 -> x = -3
So p(-3) = 0
Then
[tex]p(x) = x^3 - 4x^2 + cx + 33[/tex]
[tex](-3)^3 - 4(-3)^2 - 3c + 33 = 0[/tex]
[tex]-27 - 36 - 3c + 33 = 0[/tex]
[tex]3c = -30[/tex]
[tex]c = -\frac{30}{3}[/tex]
[tex]c = -10[/tex]
The value of c is -10.

The Royals softball team won 55 games and lost 25 games. What percent of the games did they lose? Round to the nearest whole percent.
_______% games lost
Answer:
31% games lost.
Step-by-step explanation:
Given that the Royals softball team won 55 games and lost 25 games, the following calculation must be performed to determine the percentage of games they lost out of the total games played:
55 + 25 = 80
80 = 100
25 = X
(25 x 100) / 80 = X
2,500 / 80 = X
31.25 = X
Thus, rounded to the nearest percentage, the Royals lost 31 percent of their games.

Answer:
B. Not enough information.
Step-by-step explanation:
We are given that all three angles of ∆DEF is congruent to all the three corresponding angles of ∆XYZ. However, this is is not enough to prove that they are both congruent to each other. There's no information about any of tge side length.
AAA is not a criterion that proves two triangles are congruent.
Therefore, we will conclude that there is not enough information.
b. Triangle ABC is similar to triangle EBD. Find the lengths of segments BD and BE. Show all your work.
Answer:
BD=4/3 BE=5/3
Step-by-step explanation:
by pythag theorem we can see that AC=3 and because CPCTC
AC/DE=AB/EB=CB/DB we can see that CB/DB=3/1 and CB is 4 therefore DB = 4/3 do same with BE and we get solution above.
A pair of basketball shoes was originally priced at $80, but was marked up 37.5%.
What is the new price of the shoes after the mark up?
Answer:
110
Explanation:
First move the decimal point over to the left twice.
.375
Then multiply 80 by .375 like this :
.375 x 80 = 30
Lastly, add 30 to 80 and put the dollar sign.
$110

Please help would really appreciate it!
Answer:
[tex] r = 6\sqrt{3} [/tex]
Step-by-step explanation:
Area of the shaded section = θ/360*πr²
Area = 15π m²
θ = 360° - 310° = 50°
r = ??
If in the values into the equation and solve for r
15π = 50/360 × π × r²
[tex] 15 \pi = \frac{5 * \pi * r^2}{36} [/tex]
Multiply both sides by 36
[tex] 15 \pi * 36 = \frac{5\pi * r^2}{36}*36 [/tex]
[tex] 540 \pi = 5\pi * r^2[/tex]
Divide both sides by 5π
[tex] \frac{540 \pi}{5\pi} = \frac{5\pi * r^2}{5\pi} [/tex]
[tex] 108 = r^2 [/tex]
[tex] r = \sqrt{108} [/tex]
[tex] r = \sqrt{36*3} [/tex]
[tex] r = 6\sqrt{3} [/tex]

When using substitution to solve this system of equations, what is the result of the first step?
Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
Step-by-step explanation:
Hope this helps you
Answer:
Solve. Because now you have only one variable.
