Find area of triangle ABC

Answer:

the second pair

Step-by-step explanation:

Answer:

y = − 6

Step-by-step explanation:

Answer:

x = 2 and y = 7

Step-by-step explanation:

We are given two equations:

1.      8x + y = 23

2. −10x  - y = −27

By adding both equations with each other we get:

(1.+2.) -2x = -4

Which can be reduced to:

(1.+2. : (-2)) x = 2

We can insert x in Equation 1. (or 2) and get:

8*2 + y = 23

16 + y = 23         [-16 on both sides]

y = 7

Resulting in x = 2 and y = 7 as a possible solution for this system.

Answer:

Step-by-step explanation:

8x + y = 23

-10x - y = -27

-2x = -4

x = 2

8(2) + y = 23

16 + y = 23

y = 7

Answer:

2/4 or up 2 over 4

Step-by-step explanation:

Put the points on a graph

start at the (-1,-5) and count up two

then go over 4 to the point (3,-3)

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, - 5) and (x₂, y₂ ) = (3, - 3)

m = [tex]\frac{-3-(-5)}{3-(-1)}[/tex] = [tex]\frac{-3+5}{3+1}[/tex] = [tex]\frac{2}{4}[/tex] = [tex]\frac{1}{2}[/tex]

Answer:

Interquartile Range

The interquartile range of an observation variable is the difference of its upper and lower quartiles. It is a measure of how far apart the middle portion of data spreads in value.

Interquartile Range = U pper Quartile − Lower Quartile

Problem

Find the interquartile range of eruption duration in the data set faithful.

Solution

We apply the IQR function to compute the interquartile range of eruptions.

> duration = faithful$eruptions     # the eruption durations

> IQR(duration)                     # apply the IQR function

[1] 2.2915

Answer

The interquartile range of eruption duration is 2.2915 minutes.

Exercise

Find the interquartile range of eruption waiting periods in faithful.

Answer:

5w+15v-30

Step-by-step explanation:

since m is parallel to n, this means that the two angles are alternate angles. Hence, 46°=6x-2

Calculate and you should get x = 8°

Answer:

A and E

Step-by-step explanation:

The perimeter is the length of the edge of the overall shape. In this case, the edge includes the length of the curved section of both semicircles (since semicircles are the same size, we can just find the circumference for a circle with the same radius), plus four side lengths of the square.

The radius is 10 (Two squares line up exactly with the semi-circles).

Circumference: 2πr=2π10=20π

Perimeter =20π+4(10)=40+20π

A

40+20π=40+20π? YES

B

40+20π=80+20π? NO

C

40+20π=120+30π? NO

D

40+20π=300+100π? NO

E

40+20π=10+10+10π+10+10+10π? YES

Answer:

angle DEC is 45 degrees

Step-by-step explanation:

angle DEC is 45 degrees because it is supplementary to 135 degrees

(with 135 degrees, adds up to 180 degrees)

Answer:

5

Step-by-step explanation:

Answer:

5 miles

Step-by-step explanation:

Hi there!

To find the rate at which Gia can run, you have to divide 4 by 32 to find how many miles she runs per min. When you do that, you get .125 Gia runs .125 miles per min. To find how many miles she runs in 40 min, you multiply .125 by 40 to get 5. This means that Gia runs 5 miles in 40 min.

Hope this helps :)

Answer:

818.265

Step-by-step explanation:

Answer:

0.085 m

Step-by-step explanation:

change in displ. = change in velocity ÷ change in time

so,

x = v ÷ t

= -1.7 m/s ÷ 20s

=0.085 m

Answer:

0.085 m

Answer:

P = 10w

Step-by-step explanation:

Number of point per correct spelling = 10

Number of words spelt correctly = w

Total points, p

P = (number of points per correct spelling * number of words spelt correctly)

P = 10 * w

P = 10w

Answer:

In mathematics, a ratio is a comparison of two or more numbers that indicates their sizes in relation to each other.

Step-by-step explanation:

A ratio compares two quantities by division, with the dividend or number being divided termed the antecedent and the divisor or number that is dividing termed the consequent.

Answer:

5.   y = -x

Step-by-step explanation:

First, you need to find the slope of the line.

[tex]m = \frac{2 - (-3)}{-2 - 3} = \frac{5}{-5} = -1[/tex]

Now, using either point substitute into the point-slope form for a line:

[tex]y - y_{1} = m(x - x_{1} )[/tex]

Using (-2,2) for [tex](x_{1} , y_{1} )[/tex] we get y - 2 = -1(x +2)

y - 2 = -x - 2

y = -x
