The Mount Rushmore Monument is 60 feet tall. A model of the monument is sold in the gift shop. If the model was made using a scale of 1 inch = 40 inches, how tall is the model?
Answer:huh
Step-by-step explanation:huh
The model is 28800 inches tall if the Mount Rushmore Monument is 60 feet tall. A model of the monument is sold in the gift shop.
What is a scale factor?The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
It is given that:
The Mount Rushmore Monument is 60 feet tall. A model of the monument is sold in the gift shop.
As we know, unit conversion can be defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
1 feet = 12 inches
60 feet = 60x12 = 720 inches
The scale f 1 inch = 40 inches
720 inches after scale:
= 720x40
= 28800 inches
Thus, the model is 28800 inches tall if the Mount Rushmore Monument is 60 feet tall. A model of the monument is sold in the gift shop.

SCHOOL ELECTIONS Henrietta conducted a random survey of 60 students and found that 36 are planning to vote for her as class
president. If there are 460 students in Henrietta's class, predict the total number of students who will vote for her as class president.
Answer:
276 students
Step-by-step explanation:
36/60=0.6
Therefore, 60% of students in the random survey are planning to vote for her. Using that 60%, we can predict how many students in all will vote for her.
460(0.6)=276
That means 276 students will vote for her.
Stephanie wants to make 22.5 qt. of a 20%
alcohol solution by mixing together a 6%
alcohol solution and a 36% alcohol solution.
How much of each solution must she use?
Answer:
y = 10.5qt
x = 12 qt
Step-by-step explanation:
0.6x+ 0.36y = 22.5 * 0.2
0.06x + 0.36y = 4.5
x + y = 22.5
x = 22.5 - y
0.06(22.5 - y) + 0.36y = 4.5
1.35 - 0.06y + 0.36y = 4.5
0.3y = 4.5 - 1.35
0.3y = 3.15
y = 3.15 / 0.3
y = 10.5 qt
x = 22.5 - y
x = 22.5 - 10.5
x = 12 qt

To find 1/3 of 21, we multiply the numerator 1 by the given whole number 21 and then divide the product 21 by the denominator 3.
1/3 × 21 = 1 × 21/3 = 21/3 = 7
So, 1/3 of 21 = 7.
Here are some more examples
Step-by-step explanation:
Find 2/5 of 15.
To find 2/5 of 15, we multiply the numerator 2 by the given whole number 15 and then divide the product 30 by the denominator 5.
2/5 × 15 = 2 × 15/5 = 30/5 = 6
So, 2/5 of 15 = 6.
Find 3/8 of 48.
To find 3/8 of 48, we multiply the numerator 3 by the given whole number 48 and then divide the product 144 by the denominator 8.
3/8 × 48 = 3 × 48/8 = 144/8 = 18
So, 3/8 of 48 = 18.
Evaluate.0.2 power of 4 =
Answer:
0.0016
Step-by-step explanation:
The expression 0.2 by the power of 4 when evaluated has a value of 0.0016
How to evaluate the expressionFrom the question, we have the following parameters that can be used in our computation:
0.2 by the power of 4
Express as an equation
So, we have
0.2 by the power of 4 = 0.2⁴
When expanded, we have
0.2 by the power of 4 = 0.2 * 0.2 * 0.2 * 0.2
Evaluate the products
This gives
0.2 by the power of 4 = 0.0016
Hence, the solution is 0.0016

In a 30° -60° -90° triangle, what is the length of the hypotenuse when the shorter leg is 7 in.?
Answer:
the length of the hypotenuse is 14 in
Step-by-step explanation:
Focus on the 30 degree angle. Recall that the sine of an angle is defined as
opposite side
sin Ф = ----------------------
hypotenuse
and that sin 30° is always 1/2.
7 in 1
Then sin 30° = ------------------- must equal -----
hypotenuse 2
After cross-multiplying this equation, we have 2(7 in) = (1)(hypotenuse),
so that the length of the hypotenuse is 14 in.
Interest earned: $84
Principal: 600
Interest rate: 7%
Time: ?
Answer:
2 years
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year,
then, solving our equation
t = 84 / ( 600 × 0.07 ) = 2
t = 2 years
The time required to
accumulate simple interest of $ 84.00
from a principal of $ 600.00
at an interest rate of 7% per year
is 2 years.

Answer:
25%
Step-by-step explanation:
Paso 1
Calcula la cantidad del contenedor que no estaba ocupado.
Esto se calcula como
Tamaño del recipiente: cantidad de líquido en el recipiente
= 120 lt - 90lt
= 30 litros
Paso 2
El porcentaje de la capacidad del tanque que está desocupado se calcula como:
= Capacidad del tanque que estaba desocupado / Capacidad del tanque × 100
= 30lt / 120lt × 100
= 25%
You mix 4/5 quart of blue paint for every 1/3 quart of red paint to make 3 2/5 quarts of purple paint. How much blue paint and how much red paint do you use?
Answer:
1 quarts of red paint
2.4 quarts of blue paint
Step-by-step explanation:
Let :
a = quarts of blue paint
b = quarts of red paint
a + b = 3 2/5
a + b = 3.4 - - - (1)
Ratio of a and b :
a/b = 4/5 ÷ 1/3 = 4/5 * 3/1 = 2.4
a/b = 2.4
a = 2.4b - - (2)
From (1)
2.4b + b = 3.4
3.4b = 3.4
b = 1
a + b = 3.4
a + 1 = 3.4
a = 3.4 - 1
a = 2.4
