Answer:
1/8
Step-by-step explanation:
2⁻³ = 1 / 2³ = 1 / (2*2*2) = 1/8
so the minus sign in the exponent means you can put that factor in the denominator without the minus sign.

If the ratio of boys to girls in the school band is 2 to 3, which of these show possible numbers
of the boys and girls in band.
A. 24 boys, 36 girls
B. 20 boys, 35 girls
C. 36 boys, 24 girls
D. 35 boys, 20 girls
Answer:
A
Step-by-step explanation:
Simply guess and check, meaning the boys category must be divisible by 2 and the girls category must be divisible by 3
A: 24 boys ÷ 2 = 12 (equals a whole number so it is divisible; not a decimal)
36 girls ÷ 3 = 12 (both of the boys and girls are divisible by their corresponding numbers)
Yes
Now make sure the boys are a lower count than the girls as the ratio says it should be 2 to 3, meaning there are more girls than boys
B: 20 ÷ 2 = 10 (divisible)
35 ÷ 3 = 11.666 (this is a decimal answer so it is not divisible)
No
C: 36 ÷ 2 = 18
24 ÷ 3 = 8
Yes, they are divisible
Now lets check if boys have a lower count than girls
36 boys > 24 girls
This is not the solution as it doesn't reflect the correct ratio of less boys than girls
D: 35 ÷ 2 = 17.5 (not divisible)
20 ÷ 3 = 6.66 (not divisible)
Savannah deposited $500 into an account that pays simple interest at a rate of 5% per year. How much interest will she be paid in the first 7 years?
Answer:$266
Step-by-step explanation:
Cameron :
r = 4 3/8% = 0.04375
P = 7400
For account compounded continuously :
A = Pe^it
i = interest ; t number of years ;
A = 7400 * e^0.04375*7
A = 7400 * e^0.30625
A = 10051.581
Savanna:
r = 4 3/4% = 0.0475
P = 7400
A = P(1 + r/n)^nt
n = number of compounding times per period
A = final amount ; P = initial investment
Compounded daily :
A = 7400(1 + 0.0475/365)^365*7
A = 7400(1 + 0.0001301)^2555
A = 7400(1.0001301)^2555
A = 7400 * 1.3942879
A = 10317.731
Difference :
$(10317.731 - 10051.581)
= $266.15
= $266 (nearest dollar)

Which is equivalent to (2c - 5t - 3u ) + (c + 3t ) + (3t - 4u )?
3c - 2t - 7u
3c + t - 7u
5c - 2t + 7u
2c + t - 7u
Answer:
(2c - 5t - 3u ) + (c + 3t ) + (3t - 4u )
2c-5t -3u+c+3t+3t-4u
3c+t-7u is your answer
the answer to the question above and it’s not 75
Answer:
The 2 triangles on the right and left are isosceles, so they have 2 equal sides. Consequently, the angles at the base are equal.
Because the opposite angles of a vertix are equal, the triangle in the lower part has the angles x, 58° and 47°.
Because the sum of the inner angles of a triangle is 180, x= 180- (58+47)
x= 180-105 = 75°
Pls mark as brainliest
Answer: x = 72
Step-by-step explanation:
The triangle with ∠a is an isosceles triangle; the other two angles are congruent, let them be y
a + y + y = 180 (sum of angles in triangles)
58 + 2y = 180
Subtract 58 from both sides
2y = 122
Divide both sides by 2
y = 61°
In the triangle with ∠b, b is congruent to another angle, (isosceles triangle) let it be b.
b = 47°
y and b have a relationship with the other two of the angles with ∠x (vertical angles); let them be y and b.
y + b + x = 180
61 + 47 + x = 180
108 + x = 180
Subtract both sides by 108
x = 72

Tanisha and Bess are sisters. Tanisha is half as old as Bess. Bess is 6 years older than Tanisha.
How old is each sister?
A. Tanisha is 3, and Bess is 6.
B. Tanisha is 3, and Bess is 9.
c. Tanisha is 6, and Bess is 9.
D. Tanisha is 6, and Bess is 12.
Answer: a
Step-by-step explanation: because bess it says she has 6 and is 3 it says have of 6 is 3 so it is 3
The age of Tanisha is 6 years and the age of Bess is 12 years. Therefore, option D is the correct answer.
We need to find the age of Tanisha and Bess.
What is an equation?A statement that the values of two mathematical expressions are equal (indicated by the sign =).
Let the age of Tanisha be x.
Bess is 6 years older than Tanisha.
Now, Bess=x+6
Tanisha is half as old as Bess.
Now, Tanisha=1/2×Bess
⇒x=1/2×(x+6)
⇒x=6
So, Tanisha's age=6 years and Bess's age=12 years.

What conclusion can be drawn from the quiz scores shown below?
Ken's class: 72, 78, 83, 84, 85, 87, 92
Judy's class: 76, 78, 85, 87, 89, 92, 98
Answer:
Ken class has a median of 84 while Judy class a median of 87
Step-by-step explanation:
Ken class has a median of 84 while Judy class a median of 87
Kens class has a mean score of 83, and Judy's class has a mean score of 86.43(rounded) so, judging by the mean, Judy's class is smarter. If we take a look at the median, (Ken: 84, and Judy: 87) then Judy's class is smarter. So, overall Judy's class is smarter than Ken's class.
what does this mean 4x + 6y=9
12x + 18y=27
Answer: Infinite solutions
Step-by-step explanation:
Solve4x+6y=9for x:
4x+6y=9
4x+6y+−6y=9+−6y(Add -6y to both sides)
4x=−6y+9
4x /4 = −6y+9 /4
(Divide both sides by 4)
x= −3 /2 y+ 9 /4
Substitute
−3 /2 y+ 9 /4
for x in 12x+18y=27:
12x+18y=27
12( −3 /2 y+ 9 /4 )+18y=27
27=27(Simplify both sides of the equation)
27+−27=27+−27(Add -27 to both sides)
0=0

Nicholas has a pepper shaker in the shape of a cylinder. It has a radius of 9 mm and height of 32 mm. How much pepper will for in the shaker
By using the fοrmula fοr the vοlume οf a cylinder, the pepper shaker can hοld apprοximately 8,159.15 cubic millimetres οf pepper.
What is the vοlume οf a cylinder ?The fοrmula tο calculate the vοlume οf a cylinder:
V = πr²h
where:
V = vοlume
r = radius
h = height
Tο calculate the vοlume οf the pepper shaker, we need tο use the fοrmula fοr the vοlume οf a cylinder.
In this case, we have:
r = 9 mm
h = 32 mm
Sο the fοrmula becοmes:
V = π(9 mm)²(32 mm)
V = π(81 mm²)(32 mm)
V = 81π(32) mm³
V ≈ 8,159.15 mm³
Therefοre, the pepper shaker can hοld apprοximately 8,159.15 cubic millimeters (οr milliliters) οf pepper.

Solve the two-step equation. 14=31.7-3x
Answer:
x=5.9
Step-by-step explanation:
First, you want to isolate x so you have to subtract 31.7 from both sides. This will make the equation -3x=-17.7. Because they are both sides are negative, you can change both sides to positive so it will be 3x=17.7. Next, you want x to be 1 so you have to divide 3 in both sides. This will make the equation x=17.7/3. Simplify that to get x=5.9.
