Step-by-step explanation:
find the length of a rectangle if the area is 27cm2 and the width is 3 cm
Answer: 9 cm = LEngth
Step-by-step explanation:
27/3 = L
9 = LEngth
Answer:
The length is 9cm
Step-by-step explanation:
Formula = A = l * w
We have the width which is 3
And we have the area which is 27
All we need to do is work backward
A = l * w
27 = l * 3
27/3 = l * 3/3
9 = l
The length of the rectangle is 9
We can use that to check our work and see if its correct
Check
A = l * w
A = 9 * 3
A = 27 CORRECT
Now we know it's correct
Hope this helped!

asap? for what value of x is quadrilateral CSEF a parallelogram
Answer:
6x
Step-by-step explanation:
Please help!!!!!! I’m struggling
Answer:
a < 3
Step-by-step explanation:
To do this, just solve it like an equation:
[tex]52 > -80 + 44a[/tex]
add 80 to both sides
[tex]132 > 44a[/tex]
divide both sides by 44
[tex]3>a[/tex]
or
[tex]a < 3[/tex]
Now, all you have to is graph a < 3
Answer:
a<3
Step-by-step explanation:
52>-80+44a
+80 +80
132>44a
3>a
a<3
The distance between two cities is 250 miles. About how far apart are these cities on a map that uses a scale of 1 in. = 50 miles?
Answer:
We conclude that the distance between two cities on a map = 6 inches.
Step-by-step explanation:
Given
The distance between the two cities is 250 miles.Map scale:
1 in = 50 miles
Thus, in order to determine the distance in inches between two cities on a map, all we need is to divide the original distance between two cities i.e. 250 miles by 50 miles as 1 in = 50 miles.
so
Distance between two cities on a map = 250 / 50 = 6 inchesThus, we conclude that the distance between two cities on a map = 6 inches.

Answer:
<B = 47
Step-by-step explanation:
(5x+7) = (3x+23)
5x+7 = 3x+23
2x+7 = 23
2x = 16
2x/2 = 16/2
x = 8
<B = 3x+23
<B = 3(8)+23
<B = 24 + 23
<B = 47

92°Step-by-step explanation:
Sum of internal angles of a regular polygon is:
S = 180(n - 2)We have here 5-sided polygon:
S = 180*(5 - 2) = 180°*3 = 540°Now sum the given angles measures and solve for x:
3x + 1 + 2x + 15 + 3x - 10 + 3x - 8 + 5x - 2 = 54016x - 4 = 54016x = 544x = 544/16x = 34°Find the measure of angle R:
m∠R = 3x - 10 = 3*34 - 10 = 102 - 10 = 92m∠R = 92°perform operations (5x² - 2x - 1) - (3x² - 5x + 7) =

Here are diagrams that you could use to represent base-ten units.
A diagram of base-ten units: 1 large square labeled "one.” 1 medium rectangle labeled “zero point one, or tenth.” 1 medium square labeled “ 0 point 0 one, or hundredth.” 1 tiny rectangle labeled “0 point 0 0 1, or thousandth.” 1 tiny square labeled “0 point 0 0 0 1, or ten-thousandth.”

A store is selling 4 dozen doughnuts for 24$. Based on this price, how many doughnuts could you buy for 1$
Answer:
2
Step-by-step explanation:
So first, you know that 4 dozen doughnuts = 48 doughnuts. Next, to find how much you could get for one dollar you have the ratio $24:48 doughnuts and you can divide both sides of this ratio by 24 to get $1:2 doughnuts.

Physical therapists measure strength on a dynamometer, which uses a unit called a foot-pound. Suppose you increase the strength in your elbow joint from 90 foot-pounds to 125 foot-pounds. Find the percent of increase to the nearest percent.
A.
39%
B.
138.9%
C.
28%
Answer:
A. 39%
Step-by-step explanation:
(125-90)/(90)=(35)/(90)=0.3889 or 39%
To find the percent increase, we need to divide the amount of change by the original amount.
If E and D are midpoints of ABC, find CB.
A. 3.1
B. 4.4
C. 5.2
D. 8.8
Answer:
CB is 8.8 ⇒ D
Step-by-step explanation:
In any triangle, the line segment joining the mid-points of two sides is parallel to the 3rd side and equal to half its length
In the given figure
∵ ABC is a triangle
∵ E and D are the midpoints of sides AC and AB
∵ CB is the 3rd side
→ By using the rule above
∴ ED // CB
∴ ED = [tex]\frac{1}{2}[/tex] CB
∵ ED = x + 0.7
∵ CB = 3x - 2.3
→ Substitute them in the equation above
∴ x + 0.7 = [tex]\frac{1}{2}[/tex] (3x - 2.3)
∴ x + 0.7 = [tex]\frac{1}{2}[/tex] (3x) - [tex]\frac{1}{2}[/tex] (2.3)
∴ x + 0.7 = 1.5x - 1.15
→ Subtract 1.5x from both sides
∵ x - 1.5x + 0.7 = 1.5x - 1.5x -1.15
∴ -0.5x + 0.7 = -1.15
→ Subtract 0.7 from both sides
∵ -0.5x + 0.7 - 0.7 = -1.15 - 0.7
∴ -0.5x = -1.85
→ Divide both sides by -0.5
∴ x = 3.7
→ Substitute x by 3.7 in the expression of CB
∵ CB = 3(3.7) - 2.3
∴ CB = 11.1 - 2.3
∴ CB = 8.8

Determine how much you would revive in return for a 8 year, $500 loan to a friend of you charged 3% annual interest
Answer:
The amount of annual interest you receive.
$500*8% = $40
The amount of interest you will receive for 8 years.
$40 x 8 years = $320
So after 8 years you will have a total of principal and interest .
$500 + $320 = $820

Right ADEF has sides
DE = Z, EF = y, & DF = 123
Z=p
Answer:
41 units
Step-by-step explanation:
The Pythagorean Theorem is given by :
[tex]a^2+b^2=c^2[/tex]
In a right ΔABC, AB = 40, BC = 9, & AC = x (AC is the hypotenuse)
Using the above theorem,
[tex]x^2=40^2+9^2\\\\x=41[/tex]
So, the value of AC is equal to 41 units.
