296 divide by 0.08 whats the answer plz answer, and show me how you did it plz
Answer:
Step-by-step explanation:
Ok so u can’t divide a decimal with a whole number so u have to move the decimal poin from the 8 twice so it’s on the other side of the 8 and then there shouldn’t be any zeros before the 8 now divide 296 by 8 and instead of leaving the whole number like that u have to add the decimal point to it. So it should look like this 296.00 and then u can divide which is 3,700 hope this helped <3

Which of the following represents the ratio of the short leg to the hypotenuse
in the right triangle shown below?
The ratio of the short leg to the hypotenuse of the given triangle is 1:2
What is triangle?A triangle is a polygon of three sides. In a right angled traingle we use some basic trigonometric formula. Depending upon the ratio of sides of triangle we use six trigonometric formulas.
The shorter leg of the triangle is =hypotenuse × cos60° .
[Use the formula cosθ=base/hypotenuse]
Therefore, the shorter leg= hypotenuse/2 [∵cos60°=1/2]
∴ (shorter leg)/(hypotenuse)=1/2
So, Shorter leg: Hypotenuse=1:2.
Hence the ratio of the shorter leg to the hypotenuse is 1:2.

Find the area and perimeter.
Hint: The height of a non-right triangle is the length of the segment of a line that is perpendicular to the base and that contains the opposite vertex.
A. 6x + 36; 10x + 3
B. 12x + 72; 10x + 3
C. 12x + 72; 3x + 10
D. 6x + 36; 3x + 10
Step-by-step explanation:
Perimeter = 12 + x + 6 + 2x + 5
Perimeter = 3x + 23.
Area = ½ × b × h
Area = ½ × 12 × (x + 6)
Area = 6(x + 6)

Find the value of x in the given right triangle
hi <3
you can use the sine rule in this.
first calculate the missing angle in the triangle.
we know the angles in a triangle sum to 180 so:
180 - 37 - 90 = 53
now, simply input these values into the sine rule
10/sin(53) = x/sin(37)
rearrange for x:
x = (10/sin53) x sin37
solve to get your answer of:
x = 7.5
hope this helps :)
Answer:
tanx=opposite side
adjacent side
tan(37)=x
10
x=tan(37)x10 (take cross multipication)
x=(0.753554)x10
x=7.53554

You have cup of cocoa in your cupboard. A recipe for cookies calls for 1
cup of cocoa. How much cocoa would you have left if you made the cookies?
Answer:
None
Step-by-step explanation:
sorry don't know how to delete this
Hi! I'm happy to help!
The recipe calls for 1/4 of a cup of cocoa, and we have 5/6 of a cup.
We use subtraction to solve for the difference:
5/6-1/4
To solve for this, we need to find a common denominator. We do this by finding the least common multiple of the two denominators we already have.
The least common multiple is 12, because that is the lowest number that both 6 and 4 are factors of.
We multiplied the 6 by 2 to get twelve, so, to make it equivalent, we have to multiply the 5 by 2 also.
10/12-1/4
Now, since we multiplied the 4 by 3 to get twelve, we need to do the same to the 1.
10/12-3/12
You never subtract denominators, only numerators. Now, all we have to do is 10-3:
10/12-3/12=
7/12
So, you would have 7/12 cup of cocoa left over if you made the cookies.
I hope this was helpful, keep learning! :D

Your job is 7.5 miles from home. One option is to take the back roads to work. That route is calculated for driving at an average speed of 30 miles per hour. How long will it take you to get to work this way?
Step-by-step explanation:
So if you are 7 and a half miles away, and you drive 30 miles per hour, you need to take 7.5 and divide it by it by 30 and you get 0.25, you then need to find what is a quarter (0.25) of 60 minutes, and you will find that it is 15 minutes.
So:
Answer:
The route will take 15 minutes to get to work taking the back roads.

if 5t=5 then t is what number
Answer:
1
Step-by-step explanation:
5t = 5
divide equation by 5 to get rid of it
t = 1
This is because 5t means "5 times t". The t is a placeholder for a number.
To solve for t, we divide both sides by 5
5t = 5
5t/5 = 5/5
t = 1
Note how 5t = 5 becomes 5*1 = 5 after replacing t with 1. Because 5*1 = 5 is a true statement, this helps confirm we have the correct answer.
