Working alone it takes mark 7 hours to mop the whole house it takes sue 9 determine to the nearest hundredth of the hour how long it will take then to mop the house together
Answer:
3.9375 hours
Step-by-step explanation:
Working alone it takes mark 7 hours to mop the whole house it takes sue 9 determine to the nearest hundredth of the hour how long it will take then to mop the house together
This is calculated as
1/Time it would take them to work together = 1/ Number of hours Mark mopped + 1/ Number of hours Sue mopped
= 1/T = 1/7 + 1/9
Lowest common denominator = 63
1/T = 9 + 7/63
1/T = 16/63
T = 63/16
T = 3.9375 hours

Find the value of x that makes Triangle DEF~ triangle XYZ.
Answer:
x = 4
Step-by-step explanation:
DE / XY = EF / YZ
5 / 10 = 2x-1 / 14
cross-multiply:
10(2x-1) = 14(5)
20x - 10 = 70
20x = 80
x = 4
The ratio of their corresponding side will remain constant. Then the value of x is 4.
What is the triangle?Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
The two triangles are ΔDEF and ΔXYZ.
It is given that the ΔDEF and ΔXYZ are similar.
Then the ratio of their corresponding side will remain constant. That is
[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14} =\dfrac{11}{5x +2 }[/tex]
From the first two, we have
[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14}\\[/tex]
On simplifying, we have the value of x
x = 4

a circle is divided into 9 equal parts what is the angle measure of for each part.
What value of x satisfies the equation below?
[tex]\frac{-2x - 6}{5} = 4[/tex]
Answer: -13
Step-by-step explanation:
1. Isolate x: move 5 to the otherside
=> -2x-6=4*5 => -2x-6=20
2. Move 6 to the otherside: -2x=20+6 => -2x=26
3. Divide both sides by -2
=> x=26/-2 => x=-13

Frank made cookies for his class. He gave away half of them in his first period class, but then his mom dropped off 12 more cookies. If he now has 32 cookies, how many did he start with?
Answer:
Work backwards to solve this problem.
If he ends with 32 cookies, then subtract 12. That gives 20 cookies. 20*2 is 40, so now he has 40 cookies.

Answer:
8
Step-by-step explanation:
A ball is rolled uphill a distance of 4 meters
The ball rolls downhill 12 meters before coming to rest
Therefore the ball displacement can be calculated as follows
= 12-4
= 8
Hence the displacement is 8

Answer:
Step-by-step explanation:
if 45+47=t and t=45+47 t would equal 92 in both
45+47<t than t<45+47
so basically its saying 92<t (92is less than t) and t<92 (t is greater than 92)
he is not right. When you have an equation like that the answer is 92. Its not going to be greater or less than 92. It is 92. It should be t=92
hope that masks some kind of sense. It after 1am here so I apologize if it doesn't sound right...
