Whats the formula to 10 x 13 ?

Answer:

$12.50

Step-by-step explanation:

100%-20% -> $10

80% -> $10

100% -> [tex]\frac{100}{80}[/tex] × $10 = $12.50

Answer:

1. 14m, 11, 18m

2. 132 (rounded from 131.946)

3. Quadrilateral (duh it has 4 sides) and a rhombus?

Step-by-step explanation:

1 a unique triangle is a triangle with side lengths that are ALMOST exactly like a triangle. I used the pyragothem theory (a^2 + b^2 equals c^2) and this one was soo close to 18 (17.8)

2 the equation for the circumference of a circle is C=dpi. the radius is half of the diameter so 21 time 2 is 42 then multi[ply by pi.

3 is definitely already a quadrilateral (all of them have 4 sides) and the only shade i can think of that can have a 130 degrees for 2 angles would be a longgg rhombus ( or diamond)

Answer:

18 and 72

Step-by-step explanation:

4x+x=90

5x=90

divided by 5

x=18

for the first side, since you only have x, you put 18

for the second one, since 4x, 4(18)=72

Answer:

Box A

Step-by-step explanation:

Answer:

Step-by-step explanation:

Simply we know this is an isosceles triangle meaning that:

The other angle is also 35.

With this information, we can say that as a triangle adds up to 180, we can put this in a formula:

x+35+35 = 180

x+70 = 180

x = 110

Answer:

14/24 ( simplified = 7/12)

Step-by-step explanation:

to find this we multiply the fractions 2/3 and 7/8

7/8 x 2/3 = 14/24

So Shannon ate 14/24 lb

You can simplify to = 7/12

the slopes of the sides do not matter. It's the fact that AD and BC are parallel and AB and DC are NOT parallel that determines it to be a trapezoid.

Answer: y^2 -5 + y^2 -5 + 3y^2+7y+8 + 3y^2+7y+8

Step-by-step explanation: The order doesn't matter but... its just the sides added up together. Its a rectangle so the opposites are equal. You were given 2 sides and thats all you need, just repeat it. L plus l plus w plus w is there.

Answer:

12 possible outcomes

Step-by-step explanation:

If she's spinning them at the same time, this is how you do it:

There are 3 possible outcomes on the first spinner- Walk, Run, and Stop.

There are 4 outcomes on the second spinner- Red, Green, Blue, and Orange.

Since they're being spun at the same time, we need to consider all of the possible combinations, for example:

Walk & Red.

Walk & Green.

Walk & Blue.

Walk & Orange.

And so on.  Each outcome on the first gets multiplied by 4, since there are 4 sections on the 2nd spinner.  Same thing if you did it and switched- the 4 sections on the second spinner would each have 3 different outcomes.

In conclusion, you'd just multiply 3×4, and there you go.  Or, you can think of it as 4+4+4, if that's a little easier to understand.

Answer:

[tex]10000[/tex] meters

Step-by-step explanation:

The formula for finding distance is ([tex](speed)*(time)=(distance)[/tex]). Substitute in the given values and solve to find the distance,

[tex](20)*(500)=10000[/tex]

Step-by-step explanation:

Let x be the number of households you mowed grass.

Let y be the number of households you shoveled snow.

From there, we know,

[tex]x + y = 22[/tex]

as equation 1.

next we also know,

[tex]150x + 225y = 3900[/tex]

as equation 2.

From here we know we can solve using simultaneous equations.

rearranging equation 1 with y the subject,

[tex]y = 22 - x[/tex]

Substitute this equation into equation 2.

[tex]150x + 225(22 - x) = 3900 \\ 150x + 4950 - 225x = 3900 \\ - 75x + 4950 = 3900 \\ - 75x = 3900 - 4950 \\ - 75x = - 1050 \\ x = - 1050 \div - 75 \\ = 14[/tex]

now substitute x = 14 into equation 1.

[tex]14 + y = 22 \\ y = 22 - 14 \\ = 8[/tex]

Therefore, you have mowed grass for 14 households and shovelled snow for 8 households.

Answer:

92

Step-by-step explanation:

92+88= 180 all suplementtary angles =180

Answer:

92

Step-by-step explanation:

∠X And ∠Y are supplementary.

• Measure of ∠Y = 88°.

• We have to find measure of ∠X.

• Sum of 2 supplementary angles is always = 180°.

  X+Y=180

X+88=180

X=180-88

X=92

Answer:

-60

Step-by-step explanation:

Well just follow the equation from left to right

Add it all up.
