if 45% of a number is 54,what is 65% of the number?
Answer:
78
Step-by-step explanation:
Let the number be y
45/100 * y = 54
y = 120
The number is therefore 120
Hence, 65% of 120 is 78
find the perimeter of a square equal an area to a rhombus whose diagonals are 16 and 18
Answer:
48
Step-by-step explanation:
area of rhombus = Dd/2
area of rhombus = (16)(18)/2 = 144
area of square = 144
side of square = √144 = 12
perimeter of square = 4s = 4(12) = 48

Jamie has a rectangular pool that has a length of 12 feet and a
perimeter of 40 feet. What is the width of the pool?
Answer:
8 feetStep-by-step explanation:
Given,
Perimeter of a rectangular pool (P) = 40 feet
Length of the pool (l) = 12 feet
Let,
Width of the pool be = w
As we know,
Perimeter of a rectangle = 2(length + width)Therefore,
By the problem,
=> 2(l + w) = P
[On substituting the values of l = 12 and P = 40]=> 2(12 + w) = 40
[On multiplying 2 with 12 and w]=> 24 + 2w = 40
[On subtracting both sides with 24]=> 24 - 24 + 2w = 40 - 24
[On Simplifying]=> 2w = 16
[On Dividing both sides with 2]=> [tex]\frac{2w}{2}[/tex] = [tex]\frac{16}{2}[/tex]
[On Simplifying]=> w = 8
Hence,
The required width of the pool is 8 feet. (Ans)
Answer:
The Width of the pool would be 8 feet/ft. .
Step-by-step explanation:
According to the Question Given:
Perimeter = 40 ft/feet
Length of the pool = 12 ft/feet
To Find:
The width/breadth of the pool
Solution:
We know that,
[tex] \boxed{\tt \: Perimeter \: of \: Rectangle = 2(l + b)}[/tex]
So Put their values accordingly:
Perimeter of The Rectangle = 40Length[L] = 12[tex]\longrightarrow \tt \: 40 = 2(12 + b)[/tex]
We got an equation.By this method we can easily find the breadth/width of the pool.
Solve this equation:
[tex]\longrightarrow \tt40 = 2b + 24[/tex]
Flip the equation:
[tex]\longrightarrow \tt2b + 24 = 40[/tex]
Transpose 24 to the RHS[remember to change its sign]:[tex]\longrightarrow \tt2b = 40 - 24[/tex]
Simplify:[tex]\longrightarrow \tt2b = 16[/tex]
Divide both sides by 2:
[tex] \tt\longrightarrow \cfrac{2b}{2} = \cfrac{16}{2} [/tex]
Use Cancellation method and cancel LHS and RHS:[tex]\tt\longrightarrow \cfrac{ \cancel2 {}^{1} b}{ \cancel2} = \cfrac{ \cancel{16} {}^{8} }{ \cancel2} [/tex]
[tex]\longrightarrow \tt1b = 8[/tex]
[tex]\longrightarrow \tt{b} =\boxed{\tt 8 \: feet}[/tex]
Hence, the breadth/width of the pool would be 8 ft./feet .

a farm loan officer has a four-drawer cabinet. one drawer is 3/5 full, one drawer is 1/2 full, one drawer is 2/3 full, and one drawer is 3/4 full. can the contents be combined into three drawers? explain.
Answer:
Yes
Step-by-step explanation:
3/5, 1/2, 2/3, and 3/4 must be 3 or lower if added together.
We need to find the LCM of the denominators. The LCM, or lowest common multiple, of the denominators is 60. So we have to multiply the fractions by the LCM and add them up.
36 + 30 + 40 + 45 = 151.
60 x 3 = 180.
151 isn't up to 180, so yes. And also, if you divide 151 by 60, you would get 2.52 approximately.

Answer:
A. 82°
B. 144°
C. 75°
D. 150°
E. 241°
F. 80°
Step-by-step explanation:
A circle is 360°
A. 360 - 278 = 82 °
B. 360 - (124 + 92) = 144 °
C. 360 - (255 + 30) = 75 °
D. 360 - (118 + 30 +62) = 150 °
E. 360 - (21 +41 + 57) = 241 °
F. 360 - (30 + 60 + 80 + 110) = 80°
Also, the 80° is congruent so it's the same on both sides.
Lisa charges $28 for 2 hours of swimming lessons, Tara charges $75 for 5 hours of swimming lessons. Who offers a better deal?
Answer:
Lisa
Step-by-step explanation:
Find the amount of money Lisa and Tara charge every hour.
Lisa's ratio is 28 : 2 hours
Divide both sides of the ratio by 2
Lisa charges 14 dollars per hour
Tara's ratio is 75:5 hours
Divide both sides of the ratio by 5
Tara charges 15 dollars per hour
Lisa charges 1 dollar less each hour, so Lisa offers a better deal.
Hope this helps :)

The price of a certain item changes over time. The equation y=−3.42x^2+173.64x−983.48 models the total y dollars of profit a company makes in one day on the item the when the price of the item that day is x dollars.
What is the approximate profit the company makes on the item on a day when the item price is $12?
$492.48
$607.72
$1592.68
$2574.68
Answer:$607.72
Step-by-step explanation: it’s a lot simpler than it looks. Since x represents the price of the item, you’ll have to substitute 12 dollars for x.
Making the equation, -3.42(12)^2+173.64(12)-983.48
An airplane is flying at an altitude of 33,000 feet. It needs to reduce its altitude by 6% to avoid some turbulence. After it passes the turbulence, it increases its altitude by 5000 feet.
What is the final altitude of the airplane?
Enter your answer in the box.
Step-by-step explanation:
100% = 33,000 ft
1% = 100%/100 = 33000/100 = 330 ft
6% = 1% × 6 = 330 × 6 = 1980 ft
that means the plane has to go down 1980 ft to
33,000 - 1980 = 31,020 ft
and then it goes up by 5000 ft :
31,020 + 5000 = 36,020 ft
that is the final altitude.
Answer:
The final altitude of the airplane is 36,020

(5x+...)(5x-...)=25x^2-0.16y^4
Answer:
Step-by-step explanation:
\boxed { \pink { m^{2} - n^{2} = ( m + n )( m - n ) }}
A. ( 2a + \_ )( 2a - \_ ) = 4a^{2} - b^{2}
RHS = 4a^{2} - b^{2} \\= (2a)^{2} - b^{2} \\= ( 2a + \pink {b} )( 2a - \pink {b} )
B. ( 5x + \_ )( 5x -\_ ) = 25x^{2} - 0.16y^{4}
RHS = 25x^{2} - 0.16y^{4}\\= (5x)^{2} - (0.4y^{2})^{2} \\= ( 5x +\pink {0.4y^{2} })( 5x - \pink { 0.4y^{2}} )
c) The area of a rectangle is 70 cm and it is 7 m broad. (i) Find its length (ii) Find its perimeter
Answer:
34cm
Step-by-step explanation:
[tex]Solution,\\\\Area=70cm^{2} \\\\Breadth(b)=7cm\\\\Now,\\\\Length=\frac{Area}{Breadth}\\\\Length=\frac{70cm^{2} }{7cm} \\\\Length=10cm\\\\Again,\\\\Perimeter=2(l+b)\\\\Perimeter=2(10cm+7cm)\\\\Perimeter=34cm[/tex]
The required length and perimeter of the rectangle are 7 cm and 34 cm respectively.
The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
Here,
Let the length of the rectangle be l,
Now,
According to the question,
Area of the rectangle, = l × w
70 = l × 7
l = 70 / 7
l = 10 cm
Now,
Perimeter of the rectangle = 2[l + w]
= 2 [10 + 7]
= 34 cm
Thus, the required length and perimeter of the rectangle is 7 cm and 34 cm respectively.

what is the area of the triangle
Answer:
16 square units
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
Here, it is convenient to choose the base as the vertical segment between y=-5 and y=3. Its length is 3 -(-5) = 8 units.
The height of the triangle is the difference in x-coordinates between that segment and the opposite vertex: 6 -2 = 4.
Then the area is ...
A = 1/2(8)(4) = 16 . . . square units

C. 68°
D. 22°
Angles can be measured in degrees and radians
The measure of angle XYZ is 34 degrees
How to determine the measure of XYZFrom the question, the measure of arc XY is 68 degrees
The measure of angle XYZ is then calculated as:
Angle XYZ = 0.5 * Arc XY
This gives
Angle XYZ = 0.5 * 68
Evaluate the product
Angle XYZ = 34
