A rectangular farm has an area of 5/8 square miles. If its length is 1/9 miles, what is its width?
45/8 or 5 5/8
5/8 divided by 1/9 - 5/8 x 9/1
Find the missing dimension of the prism. Volume = 532 in. 3 19 in
The required width of the rectangular prism is 16in.
What is a rectangular prism?
A rectangular prism is a three dimensional shape , that has six faces. The shape of a rectangular prism is just a cuboid shape.
Use the formula of volume of a cuboid since a rectangular prism is in the shape of a cuboid. The volume of a cuboid is V= length×breadth×height.
Given that, The volume of prism V=[tex]532 in^{3}[/tex]
The length of prism , L= 19in.
The height of prism [tex]H=1\frac{3}{4}=\frac{7}{4}[/tex].
The width, W=?
The rectangular prism has volume V=Length×Height×Width.
Therefore, 532=19×(7/4)×W
So, 532×4=19×7×W
Thus, (532×4)/(19×7)=W
Therefore, W=16in.
Thus, the width of the rectangular prism is 16in.

determine whether each pair of ratios are equivalent ratios.
1. 8/9, 72/81
2. 3/14, 21/98
3. 12/17, 50/85
Answer:
1. Equivalent
2. Equivalent
3. Not equivalent
Step-by-step explanation:
So basically for all of them you need to find a multiple for the numerator of the first fraction to see if it equals the numerator of the second fraction, and same goes for denominator.
For the first one, 8*9 is 72, and you must multiply the denominator with the same number you multiplied the numerator with, so 9*9 is 81, so it is equivalent.
Nine less than four times a number is the same as nineteen
Answer:
x= 7, the number is 7
Step-by-step explanation:
4x-9= 19
Add 9 to both sides4x=28
Divide each side by 4x=7
Answer:
4x - 9 = 19
Step-by-step explanation:
We can represent 4 times any numbers as 4x.
Then they want 9 less than 4x. This means that they want 4x but 9 units shorter. So to make 4x 9 units shorter, you would take away 9 from 4x which is represented as 4x - 9. A common mistake is writing this as 9 - 4x.
They also want 4x - 9 to be the same, or equal to, 19. So to equate both expression, you would add the equals sign between both expressions.
In a laboratory experiment, the population of bacteria in a petri dish started off at
2600 and is growing exponentially at 13% per day. Write a function to represent the
population of bacteria after t days, where the hourly rate of change can be found
from a constant in the function. Round all coefficients in the function to four decimal
places. Also, determine the percentage rate of change per hour, to the nearest
hundredth of a percent.
Answer:
See belowStep-by-step explanation:
Daily growth rate is 13% with initial values of 2600 bacteria.
The equation is:
[tex]f(t) = 2600*( 1 + 0.13)^t=2600*1.13^t[/tex]Find the hourly rate x considering 1 day = 24 hours:

How do you do Geometry the right way and what is the best way to remember how to do it?
Step-by-step explanation:
To understand geometry, it is easier to visualize the problem and then draw a diagram. If you're asked about some angles, draw them. Relationships like vertical angles are much easier to see in a diagram; if one isn't provided, draw it yourself.
when 4a - a x 3a + 7a is simplified it is equivalent to?
Answer: -3a^2 + 11a
Step-by-step explanation:
4a - (a x 3a) + 7a - Multiply first to get 4a - 3a^2 + 7a
4a - 3a^2 + 7a - Add like terms (a terms) to get -3a^2 + 11a

The perimeter of a rectangular window is 264 cm. If the width of the window is 56 cm what is its length. *
Answer:
76 cm.
Step-by-step explanation:
56 times 2 is 112
264-112=152, divide by 2
152/2=76
Answer:
76 cm
Step-by-step explanation:
Perimeter is the sum of all sides of a rectangle. It can also be thought of as 2 times the width plus 2 times the width.
[tex]P=2L+2w[/tex]
Rearranging to solve for length:
[tex]2L=P-2w[/tex]
[tex]L=\frac{P-2w}{2}=\frac{264-2(56)}{2}=\frac{152}{2}=76[/tex]
The length is 76 cm.
Name two pairs of congruent angles
Answer:
∠JKL and ∠GKH
Step-by-step explanation:
1. Because these intersecting lines are forming opposite pairs of angles, there are some vertical angles. Vertical angles are congruent.
2. As you can see, ∠JKL is 55°. The angle that forms the pair of opposite angles with ∠JKL is ∠GKH.
3. As aforementioned, because these two angles are vertical angles, they're congruent.
Therefore, two pairs of congruent angles are ∠JKL and ∠GKH.

Аx2 - 12x + 20 = 0
B(x - 4)(x – 5) = 0

Answer:
(B) (x - 4)(x – 5) = 0Step-by-step explanation:
He made a mistake at step 2.
(x - 4)(x - 5) = 0 is incorrect asit is same as x² - 9x + 20 = 0
It should be:
(x - 10)(x - 2) = 0 with the end result x = 10 or x = 2Let's solve
[tex]\\ \sf\longmapsto x^2-12x=-20[/tex]
[tex]\\ \sf\longmapsto x^2-12x+20=0[/tex]
[tex]\\ \sf\longmapsto x^2-10x-2x+20=0[/tex]
