It takes 3 people a total of 192 hours to build a wall. How long would it take if 12 people built the same wall?
Step-by-step explanation:
you need to solve this using fractions.
Example :
It takes 3 men 8 hours to build a wall. How long would it take 4 men to build the same wall?
For 3 men: It is 1 wall divided by 8 hours, which is 1/8.
For 1 man: It is 1/8 divided by 3, which is 1/24.
For 4 men: It is 1/24 multiplied by 4, which is 1/6, = 6 hours.

Find the 84th term of the arithmetic sequence 18, 31, 44, ...
Answer:
common difference = 31-18
common difference =13
from,
An=A1 +(n-1)d
A84=18+(84-1)13
A84=1097
Answer:
1097
Step-by-step explanation:
Common Difference:
d=a_2-a_1=(31)-(18)=13
d=a

How many triangles can be formed with the angle measures: 20, 70, and 90 degrees?
Answer:
A right triangle with degrees 20, 70, 90.
Step-by-step explanation:
For each one-year period after a car was purchased, its value at the end of the year was 17% less than its value at the beginning of the year. State whether the value of the car as a function of time after it was purchased is best modeled with a linear function, a quadratic function, or an exponential function and explain why. Enter your answer and your explanation in the space provided. If the value of the car 2 years after it was purchased is $17,842.51, what was the value of the car when it was purchased?
Answer:
The value of the car as a function of time after it was purchased is best modeled with an exponential function.
The Value of car when it is purchased = $25,900
Step-by-step explanation:
As given,
The value at the end of the year was 17% less than its value at the beginning of the year.
⇒ value at the end of the year = (100% - 17% ) = 83% of value at the beginning of the year.
Now,
Let the Value of car when it is purchased = x
So,
Price at the end of 1 year = 83% of x = 0.83x
Price at the end of 2 year = 83% of 0.83 x = (0.83)² x
Price at the end of 2 year = 83% of (0.83)² x = (0.83)³ x
and so on
Price at the end of n years = (0.83)ⁿ x
∴ we get
The value of the car as a function of time after it was purchased is best modeled with an exponential function.
Now,
Value of car after 2 year = (0.83)² x = $17,842.51
⇒0.6889x = $17,842.51
⇒x = [tex]\frac{17,842.51}{0.6889}[/tex] = $25,900
∴ we get
The Value of car when it is purchased = x = $25,900

Answer:
They are not congruent because they are not facing the same way.
Step-by-step explanation:
SAS stands for "side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal. If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
That is which postulate proves congruency.
Please make this Brainliest.
Answer:
They are not congruent would be my guess cause the sides are not the same my bad if it is wrong lil br uh
Step-by-step explanation:
In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. This means that either object can be repositioned and reflected (but not resized) so as to coincide precisely with the other object.
Find the value of x in the diagram below.
A. -8
B. 8
C. 98
D. 172
Answer:
x =9 and none of the choices are right as stated above
Step-by-step explanation:
Since 11x + 11 and 110 degrees are vertical angles, the two angles are congruent.
Therefore,
11x + 11 = 110 1. Subtract both sides by 11
11x = 99 2. Divide both sides by 11
x = 9

A goalie makes 12 saves in 4 games. What is the unit rate of saves per game?
Answer:
3 saves per day
Step-by-step explanation:
Since we are finding the number of saves per day, our first dividor will be the number of saves, then we divide by the other number. We have 12 saves in total, and four games, so we will have to divide.
12 divided by 4 is equal to 3.
The answer to the question must be 3.
Answer:
12 saves/ 4 games = 3 saves/ 1 game = 3 saves per game
Step-by-step explanation:
A ration is basically a division problem. Divide until you get a denominator of 1.
12/ 4 = 3/ 1
So, if he makes 12 saves in 4 games, then he makes 3 saves per game.
