Give the sum in simplest form: 4/10 + 1/10 = _____

Answers

Answer:

1/2

Step-by-step explanation:

bc 4/10 + 1/10= 5/10 divided by 2 =1/2

Answer:

1/2 or 5/10

Step-by-step explanation:

When you are adding fractions you only add the numerator (the top number) 4+1=5. So you get 5/10. But then you have to divide to get the simplest form. You can divide 10 and 5 by 5. So then after you are done dividing you end up with 1/2!

AMY~MEG AM=5 MY=7 and AY=3. A dilation was performed so that the scale factor from AMY to MEG is 1/3. Find the perimeter of MEG.

Answers

If a dilation was performed so that the scale factor from AMY to MEG is 1/3, then the perimeter of MEG will be 5 units

Dilation

Given the sides of the triangle AMY given as:

AM=5 MY=7 and;AY=3

scale factors

If the scale factor from AMY to MEG is 1/3, then the sides of triangle MEG will be:

ME = 5/3

EG = 7/3

MG = 3/3

The perimeter of MEG = ME + G + MG

The perimeter of MEG = 5/3 + 7/3 +3/3

The perimeter of MEG = 15/3

The perimeter of MEG = 5 units

Hence the perimeter of MEG is 5 units

What is m Any answers?

Answers

Answer:

B. 68°

Step-by-step explanation:

Since, opposite sides of the quadrilateral MNPQ are parallel.

Therefore, it is a parallelogram.

Measures of the opposite angles of a parallelogram are equal.

So,

(6x - 2)° = (4x + 36)°

6x - 2 = 4x + 36

6x - 4x = 36 + 2

2x = 38

x = 38/2

x = 19

[tex]m\angle M = (6x - 2)\degree \\ \\ m\angle M = (6 \times 19- 2)\degree \\ \\ m\angle M = (114- 2)\degree \\ \\ m\angle M =112\degree \\ \\ \because m\angle M + m\angle N = 180\degree \\ (adjacent \: angles) \\ \\ \therefore m\angle N = 180\degree - m\angle M \\ \\ \therefore m\angle N = 180\degree - 112 \degree \\ \\ \therefore m \angle N = 68\degree [/tex]

solve for x in both triangles

Answers

Answer:

Step-by-step explanation:

so for the triangles in 7)   they angles are the same in each, that's what the lines are saying,  that they are the same angles, and because the angle are the same, the triangles are just a scale of each other we can say that the X side is just a ratio of the other triangle , or

[tex]\frac{6}{12}[/tex] = [tex]\frac{10}{x}[/tex]

now just solve for X

[tex]\frac{12}{6}[/tex] * [tex]\frac{6}{12}[/tex] = [tex]\frac{10}{x}[/tex] * [tex]\frac{12}{6}[/tex]

x = 120/6

x=20

_______________________________

for the triangles in 8)  same thing

[tex]\frac{x}{3}[/tex] =  [tex]\frac{14}{21}[/tex]

Marissa wrote her bike to the park and back up halfway to the park she stopped at the library she was one 310 miles from the library how many miles and miles to ride her bike and all now

Answers

Answer:

5 1/5 miles

Step-by-step explanation:

Given that :

Library is located halfway between park and home ;

Distance between library and park = 1 3/10 miles

Hence, total distance between park and home :

1 3/10 + 1 3/10 = 2 6/10

The distance driven :

Home to park ; park back home

2 6/10 + 2 6/10 = 4 12/10

4 + 12/10 = 4 + 1 2/10

= 5 2/10

= 5 1/5 miles

Which linear function f has the values f(0)=3 and f(−4)=0 f(x)=34x−4 f(x)=34x+3 f(x)=43x−4 f(x)=43x+3

Answers

Answer:

[tex]f(x) = \frac{3}{4}x +3[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \frac{3}{4}x +3[/tex]

[tex]f(x) = \frac{4}{3}x-4[/tex]

Required

For which function is [tex]f(0) = 3[/tex] and [tex]f(-4) = 0[/tex] true

[tex]f(x) = \frac{3}{4}x +3[/tex]

Substitute 0 for x

[tex]f(0) = \frac{3}{4} * 0 + 3[/tex]

[tex]f(0) = 0 + 3[/tex]

[tex]f(0) = 3[/tex]

Substitute -4 for x

[tex]f(-4) = \frac{3}{4} * -4 + 3[/tex]

[tex]f(-4) = -3 + 3[/tex]

[tex]f(-4) = 0[/tex]

Hence:

[tex]f(x) = \frac{3}{4}x +3[/tex] is true for [tex]f(0) = 3[/tex] and [tex]f(-4) = 0[/tex]
