the ratio of cats and dogs at the city pound is 92 to 144.which statement descrbes this relationship?
Answer:
There are 23 cats for every 36 dogs at the city pound
Step-by-step explanation:
This means that for every group of 92 cats at the city compound there is a group of 144 dogs. So it also means that for every group of 23 cats there is a group of 36 dogs.
92 to 144 or 92/144 = 23/26 or 23 to 36
Hope This Helps OutAnswer:

Translate the following phrase to a mathematical expression.
a number times fifteen
(A) 15 n
(B) 15 + n
(D) 15 ÷ n
(C) n15
Answer:
I think C
Step-by-step explanation:
A number times fifteen would be n • 15 or just n15.
The reason it is not 15n is because it asks a "number" which in this case is represented by the letter n. That letter is now multiplied (times) by 15. So therefore the number "n" times 15 is n15.

Mary's desk was 67.94 inches long, Joe's desk was 78.26 inches long and Troy's desk was x inches long. If the length of all the desks combined was 214.62 inches, how long was Troy's desk?
Answer:
68.42
Step-by-step explanation:
We know that when we add the lengths of all of the desks together, the total is 214.62. Based on that information, we can set up the following equation: 67.94 + 78.26 + x = 214.62. From there, all you have to do is add 67.94 + 78.26 to get 146.2. Lastly, you simply do 214.62 - 146.2 to get 68.42. Hope this helps!

Answer:
A) (x+10)(x+4) = ?
B) (x+10)(x+4) = 112, solve for x
Step-by-step explanation: you multiply the two equations to get the area.
Answer:
a)[tex](x^{2} +14x+40)ft^{2}[/tex]
b)14ft, 8ft
Step-by-step explanation:
a) Area of Rectangle = Length x Breadth
= [tex](x+10)(x+4)\\=x^{2} +4x+10x+40\\=(x^{2} +14x+40) ft^{2}[/tex]
b) Given Area of rectangle = [tex]112ft^{2}[/tex]
[tex]x^{2} +14x+40=112\\x^{2} +14x-72=0 (Quadratic Equation)\\\\[/tex]
Quadratic Equations: [tex]ax^{2} +bx+c = 0\\[/tex]
In this case, a = 1, b = 14, c = -72
[tex]\frac{-b+/-\sqrt{b^{2}-4ac } }{2a} \\= \frac{-14+/-\sqrt{14^{2} 4(1)(-72)} }{2(1)} \\= 4 or - 18 (reject)[/tex]
We reject negative values.
so x = 4,
The length of table = (x+10) ft = 4+10 = 14ft
The breadth of the table = (x+4) ft = 4 + 4 = 8ft

Step 1: Find the unit rate (tomatoes per bowl)
Last time, the ratio was 9:12, or 9 tomatoes for 12 bowls of soup. To finndd the unit ratet, dividde the ffirst given unnit by the 2nd. In this case, tomatoes is the first unit, and bowls is the second. So the unit rate is:
9÷12= 0.75, or 3/4 of a tomato per bowl of soup.
Now, the ratio is 6:8, or 6 tomatoes for 8 bowls of soup. The unit rate is
6÷8= 0.75, or 3/4of a tomato per bowl of soup.
Step 2: Compare
As you can see, the number of tomatoes per bowl of soup hasn't changed at all. So the answer is C.
Hope this helps :)
Answer:
Todays’s soup will taste the same.
Step-by-step explanation:
9 tomatoes for every 12 cups of soup- ratio= 9/12=3/4
6 tomatoes for every 8 cups of soup- ratio=6/8=3/4
They both end in the same ratio, which is 3/4.

If a certain measurement of a polygon is 283 in2, it means:
A. the polygon's measurements are 283 inches by 283 inches.
B. the polygon's volume is 283 in?
C. 283 one-inch by one-inch squares will fit over its surface.
D. none of the above.
Answer: C
Step-by-step explanation:
A says the polygon's measurements are 283 inches by 283 inches. Is it Correct? No. If we multiply these numbers we get 80,089 inches squared, which is not equal to our actual surface of 283 inches squared.
B says the polygon's volume is 283 inches cubed, which is not correct because it says that a certain measurement of a polygon is 283 inches squared, not cubed, which means we got a surface/area, not a volume.
C says that our 283 inches squared area could fit 283 one-inch by one-inch squares, which is correct because one-inch by one-inch is an one inch squared area, if we multiply this one-inch squared by the number 283, we get 283 inch squared area.
And D couldn't be because the answer is C.
