Answer:

The interior angles of a triangle add to 180°:a + b + c = 180°

Angles c and d make a straight angle, which is 180°:d + c = 180°

So d + c equals a + b + c:d + c = a + b + c.

Subtract c from both sides:d = a + b.

Answer:

44ft

Step-by-step explanation:

The formula for circumference is 2 * π * radius and in this case we want to use 3.14 for π and so we do 2 x 3.14 x 7 because the radius is half of the diameter (14) and once you do that you end up getting 43.96 and once you round you get 44ft so you are correct.

Answer:

3/4

Step-by-step explanation:

1½ = 3/2

3/2 _ 3/4 =

[tex] \ \frac{3 \times 2}{2 \times 2} - \frac{3}{4} [/tex]

[tex] \frac{6}{4} - \frac{3}{4} = \frac{6 - 3}{4} = \frac{3}{4} [/tex]

(3,-1)

it should shape like a square or rectangle when you plot it

Answer:

[tex]13.51\ \text{s}[/tex]

Step-by-step explanation:

[tex]s[/tex] = Average speed of Sandra = [tex]7.4\ \text{m/s}[/tex]

[tex]d[/tex] = Distance Sandra ran = [tex]100\ \text{m}[/tex]

Time is given by

[tex]t=\dfrac{d}{s}[/tex]

[tex]\Rightarrow t=\dfrac{100}{7.4}[/tex]

[tex]\Rightarrow t=13.51\ \text{s}[/tex]

The time it takes Sandra to run the given distance is [tex]13.51\ \text{s}[/tex].

Answer:

1.07 (15 + x) = 42.80

Step-by-step explanation:

Given data

CD= $15

Let the cost of the video game be x

The total cost= 15+x

Hence the equivalent expression is

1.07 (15 + x) = 42.80

open bracket

16.05+1.07x= 42.80

42.80-16.05= 1.07x

26.75=1.07x

x= 26.75/1.07

x= 25

Check

7% tax for CD

=0.07*15

=1.05

total =1.05+15

=$16.05

7% tax for Video game

=0.07* 25

=1.75

total =1.75+25

=$26.75

In all

=26.75+16.05

=$42.8

A data set which could be represented by the box plot shown above include the following: B. 2, 3, 5, 5, 6, 7, 8, 8, 11.

In Mathematics, a box plot is sometimes referred to as a box-and-whisker plot and it can be defined as a type of chart that is used for the graphical or visual representation of the five-number summary of a data set with respect to locality, skewness, and spread.

By using the box-and-whisker plot (box plot) shown in the image attached above, the five-number summary for the given data set include the following:

By critically observing the box-and-whisker plots (see attachment), we can logically deduce that it represents all of the five-number summary for 2, 3, 5, 5, 6, 7, 8, 8, and 11.

Answer:

c = 74

d = 122

a = 58

b = 48

Step-by-step explanation:

C: a triangle always equals to 180, so 48 + 58 - 180 = 74

D: Angels next to each other on a line always equal to 180, so 180 - 58 = 122

A: Alternating interior angles of a parallel line equal to each other, so it would also be 58

B: A line is 180, so C + A - 180 = B, 74 + 58 - 180 = 48

Answer:

y = 1.5x

Step-by-step explanation:

We are to find the equation of the straight line

Using the coordinate (0, 0) and (200, 300)

Slope m = 300-0/200-0

m = 300/200

m = 1.5

Since the line pass through the origin, the y intercept is 0

Substitute m = 1.5 and b =0 into y = mx+b

y = 1.5x + 0

y = 1.5x

This gives the required equation
