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.

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.

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
So the answer in -3a^2 + 11a
A rectangular farm has an area of 5/8 square miles. If its length is 1/9 miles, what is its width?

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.

a watermelon is thrown down from the 7th floor of urey hall at ucsd. if the initial height of the watermelon is 21.0 meters, and it is thrown straight downward with an initial downward velocity of 3.00 m/s. how far will the watermelon have fallen from its starting height after 1.50 seconds?
Answer:
The watermelon has fallen 15.53625m

x=vi*t+.5*a*t^2
x=3*1.5+.5*9.81*1.5^2
x=15.53625m
Noreen can walk 1/3 of a mile in 12 minutes what is her average speed in miles per hour. (this is multiple choice)
A. 36 miles per hour
B. 12 miles per hour
C. 1/4 a mile per hour
D. 1 2/3 miles and hour
Step-by-step explanation:
1/3 mile in 12 minutes (=1/5 of an hour).
so, the speed (ratio of distance/time) is
1/3 mile / 12 minutes
the speed in mph is the converted ratio, where the denominator (bottom) is turned into 1 (hour).
what do I need to multiply 12 minutes with to get 1 hour ?
the same to multiply 1/5 with to get 1 : 5
to keep the overall value of the ratio the same I need to multiply both parts (top and bottom) of the fraction with the same value.
therefore,
1/3 / 12 × 5/5 = (1/3 × 5) / (12×5) = 5/3 / 60
so, the speed in mph is
5/3 miles / 60 minutes = 5/3 miles / 1 hour = 5/3 mph = 1 2/3 mph

4. Elias was asked to solve a quadratic equation by factoring and his work is shown below. Circle the letter of the step where he has made an error. Then redo the work correctly from that point, using the shaded space. 4 points possible Given x2 – 12x = -20
Аx2 - 12x + 20 = 0
B(x - 4)(x – 5) = 0
С x-4 = 0 OR x-4 = 0
D x = 4 or x = 5
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]
[tex]\\ \sf\longmapsto x(x-10)-2(x-20)=0[/tex]
[tex]\\ \sf\longmapsto (x-10)(x-2)=0[/tex]

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.

to find mean, add all of the numbers, and divide that by how many numbers you have.
for example:
number 7 on your paper (8,9,10,15,28)
add those numbers together to get: 70
then divide 70 by 5 (since that's how many numbers there are in the problem) to get: 14
to get median write out all the numbers from least to greatest like you've done and find the middle number by marking off a number from the side each time then you will get: 10
to find mode you just write the number that appears the most. since there are no repeating numbers in your problem, theres no mode.
to find range you subtract the smallest number from the largest number in the problem.
so in your case, it would be 28-8
your range would be: 20
