Answer:
A.5.7 minutes
B.10
Step-by-step explanation:
A. 7 tasks completed in 2/3 hours which is 40 minutes.
40/7 = 5.7, so it takes 5.7 minutes for 1 task
B. In order to find out how many tasks you can do in an hour 60/5.7 = 10.5, then round so it's 10

Find the slope from the graph.
-1/2
-4/3
3/4
-3/4
Answer: 3/4
Step-by-step explanation:
To find the slope from the graph, we need to look at the rise and run of the line. The slope is the ratio of the vertical change (rise) to the horizontal change (run).
Let's analyze the given options:
-1/2: This means that for every 2 units the line moves horizontally, it moves down 1 unit vertically.
-4/3: This means that for every 3 units the line moves horizontally, it moves down 4 units vertically.
3/4: This means that for every 4 units the line moves horizontally, it moves up 3 units vertically.
-3/4: This means that for every 4 units the line moves horizontally, it moves down 3 units vertically.
So, from the given options, the slope is 3/4. This indicates that for every 4 units the line moves horizontally, it moves up 3 units vertically.
Remember, the slope of a line is a measure of how steep the line is. It tells us how much the line is rising or falling as we move along the x-axis.
Use the slope formula to solve this question:
The slope formula is as followed:
y₂ - y₁
x₂ - x₁
where (x₁, y₁) and (x₂, y₂) are two sets of coordinates
Pick the two points on the line:
(0, 5) (4, 2)Now, plug them into the equation and solve:
y₂ - y₁
x₂ - x₁
[tex]\frac{2-5}{4-0}[/tex] = [tex]\frac{-3}{4}[/tex]
The slope of the line is -3/4
I'm doing systems of equations and inequality, solving by graphing, and was wondering how to do this problem. Thank you!
Answer:
You need to graph the two lines. The solution is the point at which they intersect.
Step-by-step explanation:
To make things easier, first, you turn the first equation into slope-intercept form:
y = 2x + 5

Alex's book has an area of 88 square inches. What are the length and wide measurements of the book?
Jorge says there are 198 inches in 5.5 yards. Is he correct. Explain your answer. Show your work.
Answer: yes, he is correct
Step-by-step explanation:
since there is 36 inches in 1 yard, we will multiply 5.5 by 36 to find out how many inches are in 5.5 yards. since 5.5 yardsx36 inches in one yard=198 inches, Jorge is correct.
Yes, he is correct, because if in one yard is 36 inches, and half a yard is 18 inches, if you multiply 36 by 5, you get 180. Then add the half yard of 18 to have 5.5 yards, or 198 inches. :)

Fredrick and Kate have 17 1/3 cups of flour. They want to make loaves of banana bread for a bake sale. Fredrick has a recipe that calls for 1 5/8 cups of flour
Kate has a recipe that calls for 1 3/4 cups of flour. Select the statements that are true.
Answer:
Fredrick's recipe will make 10 whole loaves & There will be less flour left over if Fredricks recipe is used
Step-by-step explanation:
Fredrick's recipe
17 1/3 ÷ 1 5/8 = 10 2/3
Kate's recipe
17 1/3 ÷ 1 3/4 = 9 19/21
So Fredrick's recipe will make 10 whole loaves
9 19/21 is less than 10 2/3 so there will be less flour left over if Fredricks recipe is used

Step-by-step explanation:ok so this easy enough just take a deep breath
b. x -7 = 4 + 10
= x = 4+10+7 => 21
d. 70 = 7m
=> m = 70/7. =>M= 10
f. 12 – c = 8
=> c = 12-8 => c=4
h. 2y + 3y = 4 – 6 – 13
= > 2y +3y = -15
=> 5y = -15
= > y=-15/5
=> y= -3
j. 8 = m/4
= > m = 8 x 4
=>m= 32
l) f + 4 = –6

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Step-by-step explanation:
16 over 18 equals over 100
4.5 L of orange juice is needed to add to 18 L of pineapple juice to make the fruit juice recipe with the ratio of 2 parts orange juice to 8 parts pineapple juice. The correct option is B.
What is an expression?An expression is a grouping of one or more mathematical or logical operators, operands (values, variables, or other expressions), and brackets in mathematics and computer programming that denote a computation that can be evaluated to generate a value.
The correct proportion that can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion is based on the ratio of 2 parts orange juice to 8 parts pineapple juice in the recipe. We can use this proportion to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice by cross-multiplying:
2/8 = j/18
2 × 18 = 8 × j
36 = 8j
j = 4.5
Therefore, 4.5 L of orange juice is needed to add to 18 L of pineapple juice to make the fruit juice recipe with the ratio of 2 parts orange juice to 8 parts pineapple juice.

One out of every 9 light bulbs is defective.
What constant of proportionality relates defective bulbs to total bulbs?
The constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.
What is Constant Proportionality?The ratio connecting two given numbers in what is known as a proportional relationship is the constant of proportionality. Constant ratio, constant rate, unit rate, constant of variation, and even rate of change are other names for the constant of proportionality.
Given:
One out of every 9 light bulbs is defective.
Total bulbs = 9
So, Defective bulbs = 1
Thus, Constant of proportionality = Defective bulbs / Total bulbs.
Constant of proportionality = 1 / 9
Hence, the constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.

The sum of all interior angles inside an "n" number of sides polygon is 180(n - 2) thus the measure of g will be 33 so option (A) is correct.
What is an angle?The angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
The sum of all interior angles inside an "n" number of sides polygon is 180(n - 2).
Given that a polygon with a number of sides is 24.
And the measure of one angle is 5g.
Sum of all angles = 24(5g).
24(5g) = 180(n - 2)
120g = 180(24 - 2)
g = (18/12)(22)
g = 33
Hence "The sum of all interior angles inside an "n" number of sides polygon is 180(n - 2) thus the measure of g will be 33".

Malia has $10 to spend at the fall carnival. She decides to order an ice cream cone for herself and one for her sister.
a. If the cost of each ice cream cone is $2.35, how much will she spend on the ice cream cones? Write an equation and solve.
b. How much change will Malia receive? Write an equation and solve.
Answer:
Malia's allowance changed from $10.00 to $(10 - 2x) after buying ice cream cones.
Step-by-step explanation:
We are given the following information:
Malia's allowance to spend at carnival = $10.00
Ice cream ordered by her = 2
Let x dollars be the cost of one ice cream cone.
Total money spent on ice creams =
Formula:
change in Malia's allowance = total allowance - money spent on ice cream cones = 10 - 2x
Thus, Malia's allowance changed from $10.00 to $() after buying ice cream cones.
