Step-by-step explanation:

ABCD : EFGH = 4 : 3

Therefore AD : EH is also 4 : 3.

We are given that EH = 60,

Hence AD : (60) = 4 : 3, AD = 80. (D)

Angle map and angle mac are linear pairs ,m of angle map=7x-13 and m of angle Mac =3x+13 how do u determine m of angle map
FromTheMoon [43]

Answer : ∠map = 7\times17-13=119-13=106\textdegree

∠mac = 3\times17+13=51+13=64\textdegree

Explanation:

Since we have given that

∠map and ∠mac are linear pairs

So their sum wiil be supplementary

i.e. ∠map+∠mac= 180\textdegree;

7x-3+3x+13=180\textdegree\\10x+10=180\textdegree\\10x=180\textdegree-10\textdegree\\10x=170\textdegree\\x=\frac{170}{10}\\x=17\textdegree

So, ∠map = 7\times17-13=119-13=106\textdegree

and ∠mac = 3\times17+13=51+13=64\textdegree

6 A U 3 3 1 2 3 What is the equation of the line in slope-intercept form? The equation of the line is​
AleksandrR [38]

Answer:

y = -\frac{5}{4} x+5

Step-by-step explanation:

1) First, find the slope of the line by using two points on the graph. We can see that (0,5) and (4,0) are clearly marked on the line, so let's use those points.  Use the slope formula m = \frac{y_2-y_1}{x_2-x_1} and substitute the x and y values of those points into it, then simplify:

m =\frac{0-5}{4-0} \\m = \frac{-5}{4}

So, the slope is -\frac{5}{4}.

2) Now, identify the y-intercept on the graph. The y-intercept is the point at which the line intersects the y-axis. By reading the graph, we can see that the line intersects the y-axis at (0,5), so that must be the y-intercept.

3) Substitute values for m and b in the slope-intercept formula, y = mx + b, to write the equation of the line. Since m represents the slope, substitute -\frac{5}{4} for it. Since b represents the y-intercept, substitute 5 in its place. This gives the following answer and equation in slope-intercept form:

y = -\frac{5}{4} x+5

Write a problem situation for this inequality 72-12a<24
Morgarella [4.7K]

Answer:

Subtracted 12 times a number from 72 is less than 24.

Step by step solution

Given inequality is 72-12a

We need to write in word.  

12a means 12 times a number “a”

72-12a means subtract 12a from 72.

72-12a<24 means result is less than 24.  

Inequality shows “Subtracted 12 times a number from 72 is less than 24”

If we solve for number “a”

-12a<24-72

-12a<-24

a>2

All the number greater than 2 satisfy the given inequality.

Mark estimates that the distance from his house to his school is 15.5 mi. The actual distance is 14.5 mi.
lapo4ka [179]
So the error is 1 mile

I ask what % of 15.5 = 1

How you write this;

x/100 *15.5 = 1

15.5x = 100

x = 100/15.5

x = 6.451629 round up 6.45

% error is 6.45 %

The legs of a right triangle are 5 units and 15 units. What is the length of the hypotenuse?
Varvara68 [4.7K]
To find the answer you have to use pythagorean theorem;

a² + b² = c²          where a and b are the legs and c is the hypotenuse.

5² + 15² = c²

25 + 225 = c²

250 = c²

√250 = √c²

√250 = c

hope this helps, God bless!
