Answer 1
Answer:

Answer:

x = 60

Step-by-step explanation:

The single mark on the given lines means that the lines so marked are equal.

The given triangle which contains 30 degrees in writing has another 30 degree angle. Mark the third angle as y.

The third angle is 30 + 30 + y = 180     all triangles have 180 degrees.

60 + y = 180                                            subtract 60 from both sides.

y = 120

Be very careful what you do next. The lines may be equal, but the angles are not 30 degrees as they were in the lift triangle.

The 120 degree angle is an exterior angle of the right hand triangle.

There is another angle 30 degrees where the right hand triangle has been cut of.

So

x + x  = 120                        Property of an exterior angle.

2x = 120                            Divide by 2

2x/2 = 120/2

x = 60

Answer 60

When 2 fractions refer to the same whole explain why the fraction with a lesser denominator has larger pieces than the fraction with a greater denominator

Answers

The denominator tells how many pieces the whole is broken into. So a denominator of two tells you that the whole is broken into two pieces. A denominator with 8 tells you that the whole is broken into eight pieces. Think of a pie. if it is cut into two pieces that's two halves. if it is cut into 8 pieces then that is eighths.

Marisol is painting on a piece of canvas that has an area of 180 square inches. The length of the Painting is 1 1/4 times the width. What are the dimensions of the painting

Answers

let x be a width
1 1/4x be the length (or it can be 5/4 i prefer this one)

formula for rectangle
lxw=a
5x/4(x)=180
4[5x^2/4=180]4
5x^2=720
x^2=144
x=12

so width is 12 and length is
5x/4
5(12)/4
60/4

What is the relationship with 0.04 and 0.004

Answers

Well,

You could say that 0.04 is greater than 0.004.
0.04 > 0.004

You could be more specific and say how much greater 0.04 is compared to 0.004.
0.04 = 10(0.004)

You can also make general conclusions about the two numbers.

"0.04 and 0.004 both are less than 1."

"Both numbers have fractional forms that can be simplified."

"Both numbers have a zero to the left of the decimal point."

And so on and on.

A bag contains 10 pounds of dog food. A family feeds their dogs 0.85 pound of dog food a day. How much dog food is left in the bag after 7 days? Give your answer to the nearest pound.

Answers

A bag contains 10 pounds of dog food.

A family feeds their dogs 0.85 pound of dog food a day so cin seven day the dog eats (0.85 x 7) = 5.95 pounds

so, dog food is left in the bag after 7 days is (10-5.95) = 4.05 pounds
Since there is .85 pounds of dog food fed to the dog everyday it saiz that how many are left in 7 days so our equation is 10-7(.85)=x
10-5.95=x
x=4.05
yet is says round it to the nearest pound so its 4 pounds
