-must haves:)..
step by step
right answer
makes sense
^thank you and stay safe
^^I will also mark some one the brainiest who ever answers this ;)
Answer:
10/3 lawn
Step-by-step explanation:
2/3 of a lawn in 1/5 hour
-> 1 hour cab mow = 2/3(lawn) ÷ 1/5(hour)* 1(hour)
= 10/3 = 3,666666667 lawns
Answer:
maria can mow 3 lawns
Step-by-step explanation:
if it takes 1/5 of an hour to mown 2/3 of one lawn
60 divide by .2 = 12
that means it takes 12 miuntes to mown 2/3 of a lawn, so it takes 6 minutes for each 1/3
so 12+6= 18 minutes for one whole lawn
so 18 plus 18 equals 36
so 36 minutes for 2 lawns
then add another 18 minutes and you'll get 54 minutes. That's almost a whole hour
so Maria can mown 3 lawns

A triangle was dilated by a scale factor of 6. If sin a° = four fifths and segment DE measures 30 units, how long is segment EF?
triangle DEF in which angle F is a right angle, angle D measures a degrees, and angle E measures b degrees
15.5 units
24 units
30 units
37.5 units
Answer:
24 units
Step-by-step explanation:
From the description:
angle D measures a degreesopposite to angle D is side EFside DE (which measures 30 units) is the hypotenuse of the triangle.We also know that
sin(a) = 4/5
From definition:
sin(a) = opposite/hypotenuse
Replacing:
4/5 = EF/DE
EF = (4/5)*DE
EF = (4/5)*30 = 24 units
The length of the segment EF of the triangle DEF is 24 units.
Procedure - Determination of the resulting length after dilating a triangle by a scale factorIn the image attached below we summarize the triangle described in statement, by trigonometric relationship we find that the length of the segment EF is described by the following expression:
[tex]\sin a^{\circ} = \frac{EF}{DE}[/tex] (1)
If we know that [tex]DE = 30[/tex] and [tex]\sin a^{\circ} = \frac{4}{5}[/tex], then the length of the segment EF is:
[tex]EF = DE\cdot \sin a^{\circ}[/tex]
[tex]EF = 30\cdot \left(\frac{4}{5} \right)[/tex]
[tex]EF = 24[/tex]
The length of the segment EF of the triangle DEF is 24 units. [tex]\blacksquare[/tex]

Question
How much time did a person spend at the library over a month for them to spend 40 hours reading a book?
Round your final answer to the nearest whole number.
Answer:
The correct answer will be "1.60 hours".
Step-by-step explanation:
Within this test case, let's suppose that the bookstore had been closed on Sundays every other day while there were a total of 5 Sundays throughout the month of thirty days, thus effectively.
Months = 30
Number of sundays = 5
⇒ [tex]Effective \ working \ days = Months - Number \ of \ Sundays[/tex]
⇒ [tex]=30-5[/tex]
⇒ [tex]=25[/tex]
As we know, the total spend time will be 40 hours, then
⇒ [tex]Time \ spend \ each \ day = \frac{Total \ time \ spens}{Working \ days}[/tex]
On putting the estimated values, we get
⇒ [tex]=\frac{40}{30}[/tex]
⇒ [tex]=1.60 \ hours[/tex]

m∠1 = (4x + 9)° and m∠2 = (x − 14)° in the given figure. Find x. answers: 19 7 8 37
Answer:
x = 19
Step-by-step explanation:
∠ 1 + ∠ 2 = 90° ( corresponding angle ), substitute values
4x + 9 + x - 14 = 90
5x - 5 = 90 ( add 5 to both sides )
5x = 95 ( divide both sides by 5 )
x = 19
The value of variable x is,
⇒ x = 19
We have to given that;
Measure of angles are,
m∠1 = (4x + 9)°
And, m∠2 = (x − 14)°
Now, We can see that,
Measure of angle 1 and 2 are complementary angle.
Hence, We get;
⇒ m ∠1 + m ∠2 = 90°
Substitute all the values, we get;
⇒ (4x + 9) + (x - 14) = 90
⇒ 5x - 5 = 90
⇒ 5x = 90 + 5
⇒ 5x = 95
⇒ x = 95 / 5
⇒ x = 19
Thus, The value of variable x is,
⇒ x = 19

x = 9
Answer:
x = 9
Step-by-step explanation:
Firstly, you have to balance the equation.
Start by subtracting 0.5 from both sides. Remember, when solving algebraic equations such as this one, you use reverse PEMDAS, or SADMEP.
Now, you have 0.5x = 4.5
Now, for the next step: division. Divide both sides by 0.5, or in other words, multiply by 2.

On a coordinate plane, a line goes through (0, negative 3) and (3, negative 2). A point is at (negative 4, 2).
Find the equation of the line parallel to line h that passes through (–4, 2).
y = one-third x + StartFraction 10 Over 3 Endfraction
y = negative one-third x + two-thirds
y = 3x + 14
y = –3x – 10
Answer:
Correct option: first one -> y = (1/3)x + (10/3)
Step-by-step explanation:
The linear function that represents a line is:
y = ax + b
Where a is the slope and b is the y-intercept.
First we need to find the slope of the line that goes through (0, -3) and (3, -2).
Using both points, we can find the equation of the line:
x = 0 -> y = -3
-3 = a*0 + b
b = -3
x = 3 -> y = -2
-2 = 3a - 3
3a = 1
a = 1/3
The parallel line needs to have the same slope as the line, so we can model the parallel line with the following equation:
y = (1/3)x + b
The parallel line goes through the point (-4, 2), so we have:
x = -4 -> y = 2
2 = (1/3)*(-4) + b
b = 2 + (4/3)
b = 10/3
So the equation of the parallel line is:
y = (1/3)x + (10/3)
Correct option: first one

Which function has a greater slope and y-intercept than the linear function represented in the table?
A) y=2x+8.5
B) y=3x+7.5
C) y=5x+6.5
D) y=10x+5.5
Answer:
B) y=3x+7.5
Step-by-step explanation:
The equation of the data in the table can be obtained by using any two points.
We will use points (3, 13) and (5,17)
The slope - intercept form is:
y = mx + bWe find the slope as:
m = (17-13)/(5-3) = 4/2 = 2The equation becomes:
y = 2x + bTo find the value of b, the y -intercept is:
13 = 2*3 + b ⇒ b= 13 - 6 = 7So the equation is:
y = 2x + 7Now let's compare this with the optionsA) y = 2x + 8.5

Answer:
Step-by-step explanation:
You need to get w on one side by itself.
Start out by subtracting 2l from both sides.
p−2l=2w.
Now since w is being multiplied by 2 we need to divided both sides (all terms) by 2.
w=p2−I
Answer:
W=P-L
Step-by-step explanation:
P=2L+2W
Subtract 2L from both sides.
P-2L=2W
Divide both sides by 2

A copy machine is set up to enlarge an original in the ratio 2:3.
What is this enlargement in percent?
Answer:
It should be about 67%.
Step-by-step explanation:
The ratio 2:3 is the same as the fraction 2/3.
2 divided by 3 is equal to 0.66666...
When it is rounded to the hundredths place, it is 0.67.
This means that the percentage is 67%.
Answer:
The enlarged object would be 150% larger, but the enlargement itself makes the new picture 50% larger than before as the previous size was already considered 100%.
Step-by-step explanation:
It is much easier to picture this with nice numbers.
Let's say you start with a paper that is size 100 (these numbers have no real meaning they are just for illustrating a point), this would be the 2 in the ratio so the equality would look like: [tex]\frac{2}{3}[/tex]=[tex]\frac{100}{x}[/tex]. At this point you can cross multiply and divide, getting 2x=300. By dividing by 2, you get x=150.
Now percents are out of 100, and you have one of those, only right now it is on the top. All you have to do is flip the fraction, you get [tex]\frac{150}{100}[/tex]=150% is how much it was enlarged when compared to the original, it got 1.5 times larger (you can flip the fraction because you are looking to see how much bigger it got in relation to the starting size).
However, if you are looking for only the enlargement as a percent of the total the answer would be 50% since the new size 150 is 50 larger than 100 and [tex]\frac{50}{100}[/tex]=50%.
