2.
units?
9514 1404 393
Answer:
26.75 square units
Step-by-step explanation:
Above the dashed horizontal line(s) is a triangle with base 9 and height 3.5. Its area is ...
A = (1/2)bh
A = (1/2)(9)(3.5) = 15.75 . . . . square units
__
Below the dashed horizontal line(s) is a trapezoid with bases 9 and 2, and height 2. Its area is ...
A = (1/2)(b1 +b2)h
A = (1/2)(9 +2)(2) = 11 . . . . square units
The sum of these areas is the area of the shape:
total area = 15.75 +11 = 26.75 . . . . square units

14 masons can build 2 houses in 6 months. Find how many houses 21 masons can build in the same duration.
Answer:
3 houses
Step-by-step explanation:
2 houses = 14 masons
1 house = 14 ÷ 2 = 7
Find out what 21 ÷ 7 is, which is 3.
So 21 masons can build 3 houses in 6 months.
At Silver Gym, membership is $25 per month, and personal training sessions are $30 each. At Fit Factor,
membership is $45 per month, and personal training sessions are $20 each. In one month, how many
personal training sessions would Sarah have to buy to make the total cost at the two gyms equal?
Answer:
2
Step-by-step explanation:
y = mx + b
y = total cost of the gym
m = cost per personal session
x = number of sessions
b = cost of one month
Silver gym:
y = 30x + 25
Fit Factor:
y = 20x + 45
Set them Equal to each other:
30x + 25 = 20x + 45 (get Xs on one side by subtracting 20x)
10x + 25 = 45 (isolate x by subtracting 25 from both sides)
10x = 20 (divide both sides by 10)
x = 2 personal training sessions to make the cost equal

The sum of two numbers is 54. The smaller number is 14 less than the larger number. What are the numbers?
Larger number:
Smaller number:
Answer:
larger number: 34
smaller number: 20
Step-by-step explanation:
54= y+y-14
54= 2y - 14
54+14 = 2y
68 = 2y
68/2 = 2y/2
34 = y, the larger number
y - 14 = 34-14 = 20 the smaller number
Grocery store scales are occasionally checked by inspection agencies for their accuracy in reporting the weights of purchased merchandise. Scales are allowed to operate as long as the percent error of their reported weights is within 0.5% of the actual weight measured. If you wanted to purchase 15.0 pounds of flour, what range of weights is the scale allowed to report in order to be compliant with local inspection agency regulations.
Answer:
The range of weights in the scale allowed to report in order to be compliant with local inspection agency regulations is between 14.925 pounds and 15.075 pounds.
Step-by-step explanation:
The weights should be within 0.5% of the actual weight measured.
15.0 pounds
0.005*15 = 0.075
Tolerance of 0.075 pounds
15 - 0.075 = 14.925 pounds
15 + 0.075 = 15.075 pounds
The range of weights in the scale allowed to report in order to be compliant with local inspection agency regulations is between 14.925 pounds and 15.075 pounds.

Another word for x-intercepts?
Answer:
X-intercepts are also called zeros, roots, solutions, or solution sets.
Another word for "x-intercepts" is "roots" or "zeros." These terms are commonly used in the context of mathematics, particularly when dealing with functions or equations.
X-intercepts, roots, or zeros of a function are the values of the independent variable (usually denoted as "x") for which the function evaluates to zero.
In other words, they are the points on the graph of the function where it intersects the x-axis, hence the name "x-intercepts."
Mathematically, for a function f(x), the x-intercepts are the solutions to the equation f(x) = 0.
Finding the x-intercepts of a function is essential in graphing, solving equations, and understanding the behavior of the function.
These points represent the locations where the function crosses or touches the x-axis, indicating where the dependent variable (usually denoted as "y") is equal to zero.

The table shows the amount of apple
sauce made from one apple of each size.
Patrice has 17 medium apples and 23
large apples. What is the total amount
of apple sauce that she can make with
these apples?
Patrice can make a total amount of 25.75 cups of apple sauce.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Patrice has 17 medium apples and 23 large apples.
Amount of apple sauce form a small apple = 1/3 cup
But Patrice does not have any small apples.
Amount of apple sauce from a medium apple = 1/2 cup
Amount of apple sauce from 17 medium apples = 17 × 1/2 cups
= 8.5 cups
Amount of apple sauce from a large apple = 3/4 cup
Amount of apple sauce from 23 large apples = 23 × 3/4 cups
= 17.25 cups
Total apple sauce made from 17 medium apples and 23 large apples = 8.5 cups + 17.25 cups = 25.75 cups
Hence the total amount of apple sauce that Patrice can make is 25.75 cups.

Dakota has 4/10 kg of clay he divided the clay to make eight equal parts how many grams of clay are in each pot
Answer:
Dakota must put 50 grams of clay in each pot to be able to divide the clay into 8 equal parts.
Step-by-step explanation:
Given that Dakota has 4/10 kg of clay and I divided the clay to make eight equal pots, to determine how many grams of clay are in each pot the following calculation must be performed:
4/10 kg = 0.4 kg = 400 grams
400/8 = X
50 = X
Thus, Dakota must put 50 grams of clay in each pot to be able to divide the clay into 8 equal parts.
