Answer:

1  31/40 cups

Step-by-step explanation:

Combine the fractions 7/8 c and 9/10 c:

Use the LCD 40, which is divisible by both 8 and 10.

Then we end up adding 35/40 c to 36/40 c, which yields 71/40 c.

You may either leave this result as is, or write the improper fraction 71/40 as a mixed number:  1  31/40 c.

James defines a circle as the set of all the points equidistant from a given point. His statement is not precise enough because
lana66690 [7]

A circle has a center, radius, diameter and points in a plane. Depending on the context, the definition of a circle must contain at least one of the following terms:

Center

Radius

Diameter

Points in a plane

The complete question is as follows:-

James defines a circle as "the set of all the points equidistant from a given point." His statement is not precise enough

because he should specify that

A circle includes its diameter

The set of points is in a plane

A circle includes its radius

The set of points is collinear

<h3>What is a circle?</h3>

A circle is a two-dimensional geometry on the plane having a center point and the circular line is drawn equidistant from the center point.

Based on James' definition of a circle, he needed to specify that the points are in a plane (option c).

As presented in his definition "the set of all the points" can be interpreted in several ways. Some of which are:

the set of points on a line

the set of points in a plane

the set of points in a region

Etc

Of these numerous possible interpretations, James should have specified that the set of points is in a plane

A quantity a varies directly as a quantity b, if, when b changes, a changes in the same ratio. What happens to the quantity a if
drek231 [11]
This means that if b doubles, then a will become half as large. For the inverse of the ratio 2 to 1 ("doubles") is the ratio 1 to 2 ("half"). The terms are exchanged; the inverse of the ratio a : b is the ratio b : a. When a varies inversely as b, we say that a is inversely proportional to b.

Im not really good at seventh grade math I need some help!!​
Darina [25.2K]

Answers:

1/2a= 8

Multiply by 2/1 on both sides

1/2(2/1)a= 8(2/1)

Cross out 1/2 and 2/1 equals to a

a= 16

4n= 32

Divide by 4 for both sides

4n/4= 32/4

n= 8

3x= 36

Divide by 3 for both sides

3x/3= 36/3

x= 12

m/3= 2

Multiply by 3/1 for both sides

3/1*m/3= 2(3/1)

Cross out 3/1 and 3 becomes m

m= 6

x-8= 12

Move -8 to the other side. Sign changes from -8 to +8

x-8+8= 12+8

x= 20

48= 3k

Divide by 3 for both sides

48/3= 3k/3

k= 16

13/b= 0

Multiply by 1/13 for both sides.

13/b( 1/13)= 0(1/13)

b= 0

39= 13y

divide by 13 for both sides

39/13= 13y/13

y= 3

the school swim team has 80 swimmers. the ratio of seventh grade swimmers to all swimmers is 5:16. and i have to write a proport
sertanlavr [38]
Given that the total number of swimmers is 80, and the ratio of the seventh grade swimmers to all swimmers is 5:16. You will know that answer for this through cross multiplication. So let's put it this way:
5        ?
--      ----
16     80
Multiply 80 by 5 and you get 400 then divide this by 16 and you get 25.
Therefore, out of 80 swimmers, there are 25 seventh grade swimmers. Hope this answer helps.
