Answer: 21 hours
Step-by-step explanation:
The lawn order can produce 10 landmowers in 7 hours.
This means that their speed is:
= 10/7
= 10/7 landmowers per hour
If they want to produce 30 lawnmowers, the amount of time they will take is:
= 30 ÷ 10/7 per hour
= 21 hours
can anyone please help me:)!

You and your 4 friends plane a surprise party. Each of you contributed the same amount of money "m" for food. a) Wright an algebraic expression for the total amount of money contributed for money? b) Evaluate you expression if each person get $5.25 PLEASE HELP ME OF U KNOW I WILL THANK U IF YOU WRITE THE ANSWER FOR MR THANK YOU
Answer:
a) 5m
b) $26.25
Step-by-step explanation:
You and your 4 friends plane a surprise party. Each of you contributed the same amount of money "m" for food.
a) Write an algebraic expression for the total amount of money contributed for money?
Let the total Amount of money each person contributed be = m
Since each person contributed the same amount , and there are 5 people(you and 4 friends)
The total amount of money contributed = 5 × m
= 5m
b) Evaluate you expression if each person get $5.25
From the answer in question a, we have algebraic expression = 5m
m = $5.25
Total cost = 5 × $5.25
= $26.25

This is a picture of the flag of Denmark.
On a clean page in your note book, do all the calculations to find the answer
What percent of the flag is covered in red color?
You need:
.Claim
.Evidence
.Reasoning
.All your calculations and work in detail
Answer:
76.4%
Step-by-step explanation:
Total area of flag:
LW = (37)(28) = 1036
Total area of red:
LW = (12 + 21)(12 + 12) = (33)(24) = 792
Percent of red:
792/1036 * 100% = 76.4%
Answer:
Total area of the Denmark flag:→(37×28) unit²=1036unit²
Area of the red colour of the flag:→[{2×(12×12)}+{2×(21×12)}]
=[{2×144}+{2×252}]
=[288+504]=792unit²
Percentage of the flag is covered in red color:→(792/1036)×100=0.7645×100=76.45%
76.45% is the right answer.
what information can you automatically find just by looking at a function in standard form
Answer: The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equation.
What is the slope of the line?
Answer:
slope of the line is one
Step-by-step explanation:
goes up one, over one.
The slope is 1
To find slope, you first find two points on a graph. Pick one of the two and count to the other one and that gives you your slope! I hope I helped! :)

Your bedroom wall is 150 inches wide.You want to hang two posters,each 27 inches across,with an equal space between each poster and the wall edges.
Answer:
32
Step-by-step explanation:
let the space be x
x + 27 + x + 27 + x = 150
3x + 54 = 150
3x = 96
x= 32
Read the problem in the box below. See if you can figure out the most logical
answer.
Dancing Pools sells swimming pools in 4 sizes. The small pool is
72 feet long and 18 feet wide. The medium pool is 80 feet long and
20 feet wide. The large pool is 88 by 22. If the new superduper
Coffeetable pool is 96 feet long, how wide will it be?
Answer:
I believe the answer would be 24
Step-by-step explanation:
the sequence of the pool length is by 8's
72 + 8= 80
80 + 8= 88
88 + 8= 96
and the same goes to the width and it goes by 2's
18 + 2= 20
20 + 2= 22
22 + 2= 24
The ratio of the length to the width of a rectangle is 9:4. The width of the rectangle
is 52 mm. Write and solve a proportion to find the length. Please help!! :(
Let the length be 9x and width be 4x.
4x = 52
x = 13
Length = 9x = 117 mm
what percent is 52.8 of 55? also how did u get itttt
Answer:
The answer is 96%.
Step-by-step explanation:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 55 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 55, so we can write it down as 100%=55.
4. We know, that x% equals 52.8 of the output value, so we can write it down as x%=52.8.
5. Now we have two simple equations:
1) 100%=55
2) x%=52.8
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=55/52.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 52.8 is what percent of 55
100%/x%=55/52.8
(100/x)*x=(55/52.8)*x - we multiply both sides of the equation by x
100=1.0416666666667*x - we divide both sides of the equation by (1.0416666666667) to get x
100/1.0416666666667=x
96=x
x=96
now we have:
52.8 is 96% of 55
6x + 15 = 8x + 45

Determine how many whole numbers have square roots between 5 and 6. Show your work.
Step-by-step explanation:
We are looking for possible values of n in
5 < √n < 6, where n is a whole number.
(5)² < (√n)² < (6)² is allowed as all are positive.
25 < n < 36
Therefore there are 36 - 25 - 1 = 10 values for n.

Every day of the week. Jordan eams $4 per hour for delivering newspapers He also earns a weekly bonus of $14 if he arrives on time to work each day Last week Jordan arved on time to work every day and earned a total of $108 for h hours of work Based on this situation, which belongs to p in the form px + q = ?
Answer:
(D) Jordan worked a total of 21 1/2 hours.
Step-by-step explanation:
Solution: m=money made
h=hours worked
m=$4(h)+$10
$96=$4(h)+$10 subtract the 10
$86=$4(h) divide by 4
21.5=h
how do i write an equation of a quadratic formula when given the roots and y intercept? is there a formula i can plug the numbers in or something?
9514 1404 393
Answer:
y = -3x^2 +3x +6
Step-by-step explanation:
For roots p and q, the equation can be written as ...
y = a(x -p)(x -q)
The value of 'a' must be determined so that the product apq is equal to the y-intercept. One could say that the formula is ...
y = (y-intercept)/(pq)·(x -p)(x -q)
For your given values of p = 2, q = -1, y-intercept = 6, this becomes ...
y = 6/(2(-1))(x -2)(x +1)
y = -3(x^2 -x -2) . . . . . simplifying a bit
y = -3x^2 +3x +6

is 1 1/2 equal to 1 to 2? why or why not
Answer:
No
Step-by-step explanation:
1 to 2 is 1/2
Answer:
No. See below.
Step-by-step explanation:
I've never heard anyone say this out loud. However, on Brainly, it is always interpreted as 1 1/2 = 1.5. So it is 1 plus 1/2.
1 to 2 is a ratio. For every set of car keys I have 2 house keys.
1 to 2 can be written either as 1/2 or 1:2 depending on how touchy your instructor is.
So no. 1 1/2 is not the same as 1:2
