Please help me with his problem

Mathematics
1 answer:
zubka84 [21]3 years ago
7 0

Answer:

g. m∠1 = m∠3

Step-by-step explanation:

F would be false because m∠1 does NOT equal m∠2, if it did the wood would be perpendicular.

H is true, but not the correct answer. None of the angles given are on the other piece of parallel wood, giving nothing to compare.

J would be false because m∠3 does NOT equal m∠4, if it did the wood would be perpendicular.

G is correct, because it is a true statement that gives an angle on each piece of wood.

The graph shown compares the number of pages of the same book read by Emily and Serena over time.
iragen [17]

Using linear equations, the number of minutes that both would read for them to read equal number of pages is: 30 minutes.

<h3>What is the Equation of a Linear Graph?</h3>

Equation of a linear graph is given as, y = mx + b, where m and b are the slope and y-intercept of the graph respectively.

Equation for Emily's graph:

Slope (m) = rise/run = 1/3

y-intercept (b) = 2

Substitute m = 1/3 and b = 2 into y = mx + b

y = 1/3x + 2

Equation for Serena's graph:

Slope (m) = rise/run = 2/5

y-intercept (b) = 0

Substitute m = 2/5 and b = 0 into y = mx + b

y = 2/5x + 0

y = 2/5x

To find how many minutes for both of them to read the same number of pages, make both equations equal to each other.

2/5x = 1/3x + 2

2/5x - 1/3x = 2

1/15x = 2

Multiply both sides by 15

x = (2)(15)

x = 30

The answer is 30 minutes for both to read the same number of pages.

What is the average of -2.6, 1.8, -3.3, -2.7, 2.2 ?<br> I dont understand this.
olya-2409 [2.1K]
Average = Mean

To find the mean, add up the numbers and divide it by how many numbers there are.

So,  -2.6+1.8+(-3.3)+(-2.7)+2.2=-4.6

There are 5 numbers in total.

-4.6 \div 5=-0.92

To do these types of division, ignore the decimal and add a 0 at the end.

So we can do:
-460\div5=-92

And put back the decimal.
Hope this helps :)

Solve for x and find the lengths.<br> x=<br> DE= x + 7<br> EF = 7<br> 4x+2
Korolek [52]

Answer:

see explanation

Step-by-step explanation:

from the diagram

DF = DE + EF , that is

4x + 2 = x + 7 + 7

4x + 2 = x + 14 ( subtract x from both sides )

3x + 2 = 14 ( subtract 2 from both sides )

3x = 12 ( divide both sides by 3 )

x = 4

Then

DE = x + 7 = 4 + 7 = 11

DF = 4x + 2 = 4(4) + 2 = 16 + 2 = 18
