The 7 rounds up the .9, adding 1 to the ones place, making it 622
Answer:
620
Step-by-step explanation:
As they said TENS ( and not TENTHS ) place, the 1 ( in ones position) determines the answer hence 620.

Answer:
88
Step-by-step explanation:
m<ACB is equal to m<ABC because when to split the triangle down the middle and reflect one half you would have the same open shape. So by knowing that, you add 46+46 to get 92. Also knowing a triangle is equal to 180, you would end up subtracting 92 from 180 to get 88.
hope this helps!
Can you divide 38 by 4 evenly? Use the number line to explain your answer. 38 You cannot divide 38 by 4 evenly. Using the number line, you can count back from 38 by 4s times until you reach the number . Then you cannot count back by 4 any more, so the remainder is .
Answer:
No there will be 2 left.
Step-by-step explanation:
count backwards from 38 by 4's
Answer my math question I asked so many times I lost most of points by
Answer:
Step-by-step explanation:
Parabolas can be written in the form
[tex]y = a(x-h)^2+k[/tex]
The vertex is (h, k). The vertex in the graph is (5, 0).
so far, we have
[tex]y = a(x-5)^2+0\\y = a(x-5)^2[/tex]
The other points we are given are (6, 1), (7, 4), (8, 9)
[tex]9 = a(8-5)^2\\9 = a(3)^2\\9 = 9a\\a = 1\\\\4 = a(7-5)^2\\4 = a(2)^2\\4 = 4a\\a = 1\\\\1 = a(6-5)^2\\a = 1[/tex]
In vertex form
[tex]y = (x-5)^2\\y = x^2 - 10x + 25[/tex]

Two rectangular prisms are similar. The ratio of the areas of the bases is 121:49. What is the ratio of the volumes of the similar solids?
Answer:
The ratio of the volumes of the similar solids is 1331:343.
Step-by-step explanation:
Ratios
Given the ratio of two lengths is a:b. Given a two-dimensional shape is similar to another shape, the ratio of their areas is [tex](a/b)^2[/tex], and the ratio of their volumes is [tex](a/b)^3[/tex].
We know the ratio of the areas of the bases of two similar rectangular prisms is 121:49. Thus, the ratio of its dimensions is:
[tex](a/b)^2=(121/49)[/tex]
Taking the square root:
[tex]a/b = \sqrt{121/49}=11/7[/tex]
Thus, the ratio of the volumes is:
[tex](a/b)^3=(11/7)^3=1331/343[/tex]
The ratio of the volumes of the similar solids is 1331:343.

a 12 inch candle burns down in 12 hours. at what rate does the candle burns, in inches per hour?
Answer:
1 inch per hour because it took 12 hours to burn a 12 inch candle so 1 inch per hour
The candle burns at a rate of 1 inch per hour.
What is a unitary method?
A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, A 12-inch candle burns down in 12 hours.
∴ The rate at which it burns per hour is the total length of the candle divided by the total time it brunt for which is,
= (12/12) inch/hr.
= 1 inch/hr,

write an equation for a line through (1,-1) and (2,3)
Answer:
y = 4x - 5
Step-by-step explanation:
Use the point slope form and add in the ordered pairs [tex]\frac{3 + 1}{2 - 1}[/tex] , and once you solve this it equals [tex]\frac{4}{1}[/tex], or just 4. Now you have the first part of your equation, y = mx + b, but now you have y = 4x + b. To find b, substitute the x and y values of one of the given ordered pairs in for x and y in the equation, and I am using (2,3). The equation now looks like this: 3 = 4(2) + b. Now solve: 3 = 8 + b
Subtract 8 from both sides to get -5 = b. Now you have a full equation: y = 4x -5

Explain why you write a mixed number as a fraction before using it as a dividend or divisor.
Answer:
I think it's because it is easier to solve when put into equations.

Frank bought 5 pounds of dog food for 8.75. At this rate how much would he pay for 8 pounds
$14
you need to set up a preportion
if 5 lbs costs 8.75 then we need to figure out how much 8 lbs cost, obviously lol.
anyways what ya finna do is make a fraction
5 8
--- = ----
8.75 x
then u cross multiply. 8 x 8.75 = 70
70 = 5x
x= $14
