Mathematics
1 answer:
S_A_V [24]2 years ago
7 0

Answer:

13/48

Step-by-step explanation:

I take the middle sign to be plus.\

3/4//4/5 = 3/4 * 5/4 = 15/16

15/16 - 2/3 =

The lowest common denominator would be 48: 16 and 3 are prime to each other.

45/48 - 32/48 = 13 / 48

Where did the minus come from? I take it that there is a minus sign in front of the 2

HURRY!!!!! I NEED HELP!!!!!<br>Find Arc MN <br><br><br>A. 20<br><br>b.60<br><br>c.66<br><br>d.120
Ad libitum [116K]

We have been given a circle. We are asked to find the measure of arc MN.

We know that the measure of all arcs in a circle is equal to 360 degrees. SO we can set an equation as:

\widehat{MN}+\widehat{NO}+\widehat{OL}+\widehat{LM}=360^{\circ}

Upon substituting our given values, we will get:

\widehat{MN}+110^{\circ}+130^{\circ}+54^{\circ}=360^{\circ}

\widehat{MN}+294^{\circ}=360^{\circ}

\widehat{MN}+294^{\circ}-294^{\circ}=360^{\circ}-294^{\circ}

\widehat{MN}=66^{\circ}

Therefore, measure of arc MN is 66 degrees and option 'c' is the correct choice.

The perimeter of a rectangular piece of paper is 52 inches. The area is 133 square inches. What are the dimensions of the paper?
valkas [14]

Answer:

7 inches by 19 inches

Step-by-step explanation:

We can use a system of equations for this.

<em>x=length</em>

<em>y=width</em>

2x+2y=52 (Perimeter)

xy=133 (Area)

We must find x and y that fit both these equations.

Hope this helps :)

The slope is -2/5x therefore plug in x and then add that to your y

your y right now is -1 as thats where x=0 is

the equation of this line is y= -2/5x -1

Marissa rode her bike to the park and back home. She lives 2 3/10 miles from the park. How many miles did Marissa ride her bike
Dovator [93]
2\frac{3}{10} +2\frac{3}{10} =\frac{(2\times10)+3}{10}+\frac{(2\times10)+3}{10} =\frac{20+3}{10}+\frac{20+3}{10}\\\\=\frac{23}{10} +\frac{23}{10} =\frac{23+23}{10} =\frac{46}{10} =4\frac{6}{10} =\boxed{\bf{4\frac{3}{5}}}

Marissa rode 4 3/5 miles in all.
