The area of a rectangle is 14 square units. It has side lengths a and b. Given the following value for a, find b. a = 2 & 1/3
Given:
The area of a rectangle = 14 square units.
The side lengths are a and b.
[tex]a=2\dfrac{1}{3}[/tex]
To find:
The value of b.
Solution:
We know that, the area of a rectangle is:
[tex]Area=Length\times Width[/tex]
The area of the given rectangle is:
[tex]14=a\times b[/tex]
[tex]14=2\dfrac{1}{3}\times b[/tex]
[tex]14=\dfrac{2(3)+1}{3}b[/tex]
[tex]14=\dfrac{6+1}{3}b[/tex]
On further simplification, we get
[tex]14=\dfrac{7}{3}b[/tex]
[tex]14\times 3=7b[/tex]
[tex]42=7b[/tex]
Divide both sides by 7.
[tex]\dfrac{42}{7}=b[/tex]
[tex]6=b[/tex]
Therefore, the value of b is 6 units.

How many times larger is 6*10^ 7 than 3*10^ 6 ?
Answer:
20
Step-by-step explanation:
step 1: Evaluate the expressions
6*10^7 = 60,000,000
3*10^6 = 3,000,000
step 2: Devide
60,000,000 / 3,000,000 = 20
so 60,000,000 is 20 times larger than 3,000,000
Your teacher might want you to use a different method, but I believe this is the simplest way. If you have any questions feel free to ask away
Answer:
20
Step-by-step explanation:
[tex] \dfrac{6 \times 10^7}{3 \times 10^6} = \dfrac{6}{3} \times 10^{7 - 6} = 2 \times 10^1 = 20 [/tex]

504
Step-by-step explanation:
first you would multiply 6 * 15 * 4 for the bases. then you multiply 6 *12*2 for the ends. that leaves you with 360 and 144. you add those two together to get 504
Find the area of the figure. (Sides meet at right angles.)
Answer: 37ft^2
Step-by-step explanation:
Create two separate figures. A full square 3x3 and a rectangle 7x4.
The 7ft line on the right minus 3 ft (because we are cutting out that section of the figure) = 4ft
Area of 3x3 square = 3^2 = 9ft^2
Area of 7x4 rectangle = 7x4 = 28ft^2
28+9= 37ft^2
What is the length of the hypotenuse?
Answer:
The answer is c = 17 feet
Step-by-step explanation:
The formula to find the hypotenuse is a^2 + b^2 = c^2 (a squared plus b squared equals c squared).
a = 8 feet
b = 15 feet
a^2 = 8 * 8 = 64
b^2 = 15 * 15 = 225
The next step is to add: 64 + 225 = 289
But we need to remember to square root 289 because we squared a and b.
The square root of 289 equals 17
c = 17 feet
A restaurant is making table cloths for their four round tables. Each table is a circle with a radius of 2 ft. Each table cloth needs to be 20% larger than the table surface.
How many whole table cloths can the restaurant get out of a piece of fabric with an area of 64 ft²?
Please help!!
Answer:
4
Step-by-step explanation:
Since it gives us the amount of area of material to use we know we want to find how many times we can divide it into tablecloths. So now we need to find how much each tablecloth is.
so first it tells us that each table has a radius of 2 ft, so we find the area using that. area of a circle is [tex]\pi r^2[/tex] so plugging in 2 ft we get 4π square feet or 12.56.
It also says that each tablecloth needs to be 20% bigger, so we find what 20% larger than 4π is. to do this you do 4pi*1.2 = 4.8π = 15.072 square feet.
Now, how many tablecloths with areas of 15.072 square feet can be made from 64 square feet. Hopefully it's obvious you divide. so 64/15.072 = 4.25
Since we want whole tablecloths and that .25 is a remainder, 4 whole tablecloths can be made.

Given AB= 20, BV=12, VA=14 and SR is a mid segment, find the given lengths
Given:
AB= 20, BV=12, VA=14 and SR is a mid segment.
To find:
The lengths of SR and AR.
Solution:
SR is a mid segment. So, SR is parallel to the non-included side BV and the length of SR is half of BV.
[tex]SR=\dfrac{1}{2}BV[/tex]
[tex]SR=\dfrac{1}{2}(12)[/tex]
[tex]SR=6[/tex]
SR is a mid segment. So, it divides the included sides in two equal parts. It means R is the midpoint of VA.
[tex]AR=\dfrac{1}{2}VA[/tex]
[tex]AR=\dfrac{1}{2}(14)[/tex]
[tex]AR=7[/tex]
Therefore, the measure of SR is 6 units and the measure of AR is 7 units.

The expression ax²+bx+c is divisible by x-1, has a
remainder of 2 when divided by x+1 and has a remainder of 8 and when divided by x-2 find the values of a, b, and c and
factorise completely.
Answer:
(x - 1)(3x + 2)
Step-by-step explanation:
By the Remainder theorem
Given expression is divisible by x - 1 then f(1) = 0
when divided by (x + 1) then f(- 1) = 2
when divided by x - 2 then f(2) = 8
Substitute x = 1, x = - 1, x = 2 into the expression , that is
a + b + c = 0 → (1)
a - b + c = 2 → (2)
4a + 2b + c = 8 → (3)
Subtract (1) from (2) to eliminate a and c
- 2b = 2 ( divide both sides by - 2 )
b = - 1
Subtract (1) from (3) to eliminate c
3a + b = 8 ← substitute b = - 1
3a - 1 = 8 ( add 1 to both sides )
3a = 9 ( divide both sides by 3 )
a = 3
Substitute a = 3, b = - 1 into (1) and evaluate for c
3 - 1 + c = 0
2 + c = 0 ( subtract 2 from both sides )
c = - 2
Then a = 3, b = - 1, c = - 2
Thus
ax² + bx + c
= 3x² - x - 2
= (x - 1)(3x + 2) ← in factored form
Rewrite in factored form. g(x)=2x^2+10x+12
Answer:
. g(x)=2x^2+10x+12=2x²+6x+4x+12=2x(x+3)+4(x+3)
=(x+3)(2x+4)=2(x+2)(x+3)
Answer:
2(x + 3)(x + 2)
Step-by-step explanation:
All three terms of g(x)=2x^2+10x+12 have the factor 2, so
g(x)=2x^2+10x+12 = 2(x^2 + 5x + 6).
This can be factored further, into:
2(x + 3)(x + 2)

Which of the following statements must be true?
A. The measure of angle AGB is greater than the measure of angle ADE.
B. The measure of angle AGB is greater than the measure of angle AED.
C. Segment AE and Segment AB have the same length.
D. The ratio of AG to AE is the same as the ratio of AB to AD.
Answer:
D
Step-by-step explanation:
....iam not sure but i think its a because the other impossible
Answer:
The answer is D.
Step-by-step explanation:
For A- I don't think it's greater, I think they are the same.
For B- I don't think it's greater, I think they are the same.
For C- Segment AE is longer than Segment AB.
So D seems like the more logical answer.
What is the slope of a line that goes through the points (10, -2) and (5,-5)? m =
Y1-Y2
11-12
Answer:
m = 3/5
Step-by-step explanation:
use the formula so m = -5 - -2 / 5 - 10 , so m = -5+2 / -5
m = -3/-5 so m = 3/5
What is the measure of < c in quadrilateral ABCD?
Answer:
the sum of interior angles of a quadrilateral = 360 degree
Step-by-step explanation:
therefore,
let the angle C be X
124 + 96 + 94 + X = 360
314 + X = 360°
X = 360 - 314 = 46°
angle C = 46°
Answer:
46 degrees
