The equation 7(u-5)=21 is solved in several steps below. For each step, choose the reason that best justifies it.
Answer:
[tex]u = 8[/tex]
Step-by-step explanation:
The steps are not shown. So, I will solve from scratch
Given
[tex]7(u -5) = 21[/tex]
Required
Solve, with steps
[tex]7(u -5) = 21[/tex]
Apply distributive property
[tex]7u - 7 * 5 =21[/tex]
[tex]7u - 35 =21[/tex]
Collect like terms
[tex]7u = 35 + 21[/tex]
[tex]7u = 56[/tex]
Divide both sides by 7
[tex]\frac{7u}{7} = \frac{56}{7}[/tex]
[tex]u = 8[/tex]
If the sandbox at the playground is 22 feet long and 17 feet wide what would be the shortest distance to get from one side of the sandbox to the other?
Answer:
Step-by-step explanation:
Assuming that the sandbox has a rectangular shape, move from one side in a perpendicular direction to the other side. For example, draw a line perpendicular to one of the 22-ft-long sides to the other; the shortest distance from one of these sides to the other is 17 ft, the shortest possible such distance.
Answer:
17 feet

∠1 and ∠2 are supplementary angles. ∠1 and ∠3 are vertical angles. If m ∠2=72 degrees, then find m ∠3
Answer:
m<3 = 108
Step-by-step explanation:
Since <1 and <2 are supplementary, the equation is:
<1 + <2 = 180
Since <1 and <3 are vertical angles. the equation is:
<1 = <3
To find m<3:
<2 + <3 = 180
72 + <3 = 180
<3 = 180 - 72
<3 = 108
The measure of angle ∠3 is 108 degrees.
What is supplementary angle?Supplementary angles are those angles that sum up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees.
What is vertical angle?Vertical angles are formed when two lines meet each other at a point. They are always equal to each other.
For the given situation,
∠1 and ∠2 are supplementary angles.
∠1 and ∠3 are vertical angles.
Measure of angle, m ∠2 = 72
From definition, we know that
∠1 + ∠2 = 180 (supplementary angles) ------- (1)
and
∠1 = ∠3 (vertical angles) --------- (2)
From (1) and (2),
⇒ [tex]\angle3 + \angle2 = 180[/tex]
⇒ [tex]\angle3=180-72[/tex]
⇒ [tex]\angle3=108[/tex]
Hence we can conclude that the measure of angle ∠3 is 108 degrees.

Which inequality matches the given situation if w represents weight in pounds:Baby tigers can be no larger than 4 pounds.
Given:
w be the weight in pounds of a baby tigers.
To find:
The inequality if baby tigers can be no larger than 4 pounds.
Solution:
Baby tigers can be no larger than 4 pounds. It mean weight of baby tigers cannot be greater than 4. In other words, the weight of the baby tigers must be less than or equal to 4.
Let w represents weight in pounds and the weight of the baby tigers must be less than or equal to 4. So,
[tex]w\leq 4[/tex]
Therefore, the required inequality is [tex]w\leq 4[/tex].

A rectangular container with a base of 24 inches by 15 inches is 1/3 filled with water. If all the water is poured into an empty rectangular container measuring 12 inches by 18 inches by 10 inches, it will fill the second container to its brim. What is the height of the first container?
Answer:
18 inches
Step-by-step explanation:
volume of a cuboid = length x breadth x height
the following equation can be derived from the question
let h = unknown height
1/3(24 x 15 x h) = (12 x 18 x 10)
Multiply both sides of the equation by 3
(24 x 15 x h) = (12 x 18 x 10) x 3
Divide both sides of the equation by (24 x 15)
h = 18 inches

A cooler shape of a rectangular prism. What is the volume of the cooler? Round to the nearest tenth if necessary.
Answer:
Volume of the cooler = 2,772 in³
Step-by-step explanation:
Volume of the cooler = length × width × height
Length = 22 in
Width = 12 in
Height = 10 1/2 in
= 21/2
= 10.5 in
Volume of the cooler = length × width × height
= 22 in × 12 in × 10.5 in
= 2,772 in³
Volume of the cooler = 2,772 in³

Answer:
It is a permutation problem. There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.
Step-by-step explanation:
In this case, the company will hire four different applicants from a group of 40 people for 4 different jobs. In this case, we need to consider the effect of order in the number of possibilities. Hence, we must use the permutation formula:
[tex]_{n} P_{k} = \frac{n!}{(n-k)!}[/tex] (1)
Where:
[tex]n[/tex] - Total of applicants.
[tex]k[/tex] - Selected applicants.
If we know that [tex]n = 40[/tex] and [tex]k = 4[/tex], then the number of possibilities is:
[tex]_{40}P_{4} = \frac{40!}{(40-4)!}[/tex]
[tex]_{40}P_{4} = 40\times 39 \times 38 \times 37[/tex]
[tex]_{40}P_{4} = 2193360[/tex]
There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.
Por una falda que costaba 50 € Adela apagado en las rebajas 45 ¿Qué tanto por ciento de rebaja tenía la falda
Answer:
El porcentaje de descuento fue del 10%.
Step-by-step explanation:
Para encontrar el porcentaje de descuento, puedes calcular la variación entre los dos precios ya que este será el porcentaje aplicado. Para hacerlo debes calcular la diferencia entre los dos precios restando el precio final menos el precio original y luego, debes dividir este resultado entre el precio original y multiplicar por 100:
Precio original=50
Precio final=45
((45-50)/50)*100
(-5/50)*100=-0.1*100=-10%
De acuerdo a esto, la respuesta es que el porcentaje de descuento fue del 10%.
