Answer:
Sam average speed for the whole journey = [tex]3\frac{3}{11} mph[/tex]
Step-by-step explanation:
Formula: Speed = [tex]\frac{Distance}{Time}[/tex]
i.e. Time = [tex]\frac{Distance}{Speed}[/tex]
If Sam walked x miles at 4 mph, then time taken by him = [tex]\frac{x}{4}[/tex] hours
If he then walked 2x miles at 3 mph, then time for this period = [tex]\frac{2x}{3}[/tex]hours
Average speed = [tex]\frac{Total Distance}{Total Time}[/tex]
=[tex]\frac{x+2x}{\frac{x}{4} \frac{2x}{3} }[/tex]
=[tex]\frac{3x}{\frac{x1}{4} \frac{2}{3} }[/tex]
=[tex]\frac{3}{\frac{3+8}{12} }[/tex]
=[tex]\frac{3 x 12}{11}[/tex]
=[tex]\frac{36}{11}[/tex]
=[tex]3\frac{3}{11} mph[/tex]
Hence, Same's average speed for the whole journey = [tex]3\frac{3}{11} mph[/tex]
Can you guys please answer this is really important
Answer:
B) BC'= 8, m A'= 28°
Step-by-step explanation:
When dilating a figure, it increases its size or decreases. In this case, as it is dilating by a factor of 1/2, you can assume it decreases.
To find the value of the new figure, A'B'C', you have to multiply the factor times the lengths of the triangle, or, the only one they are asking for in this case, the length BC':
BC' = BC×1/2BC' = 16×1/2BC' = 8The angles, otherwise, do not change. When figures are dilated, they are similar. The properties of similar figures are that they have congruent angles, therefore, the same angles. They do not have any effect caused by the factor, so m A' stays at 28°.

Omar divided a circular pizza into 8 equal sections. He gave his friend
3 sections. Explain why the amount he gave to his friend can be represented
by a point plotted to the right of 0 on a number line. Then write the
amount he gave to his friend as a decimal.
Answer:
the amount he gave his friend is a positive fraction, therefore to the right of 0 on the number line. the decimal is 3/8 which = 0.375

What is the interquartile range of warrens data?
Answer:
10
Step-by-step explanation:
Answer:
To find the interquartile range, first arrange the values in the data set in ascending order:
0, 5, 5, 10, 10, 10, 15, 15, 15, 20, 20, 20, 25, 25, 30.
Because there are 15 values in the data set, the first quartile is the 4th value, which is 10, and the third quartile is the 12th value, which is 20.
interquartile range
=
third quartile – first quartile
=
20 – 10
=
10
The interquartile range of Warren's data is 10.
For which value of is the following number undefined
x - 3 / x + 4
Answer:4x - 2 = 3x + 1
Step-by-step explanation: shooooooooo papi
Answer:
x = - 4
Step-by-step explanation:
The denominator of the rational expression cannot be zero as this would make it undefined.
Equating the denominator to zero and solving gives the value that x cannot be, that is
x + 4 = 0 ⇒ x = - 4
Thus x = - 4 is the excluded value

Activity
Andrew is paid $4 per hour for the first 30 hours he works each week. He makes $5 per hour for each hour he works over 30 hours per week. In
other words, total wages = fixed wages for 30 hours + additional wages at $5 per hour.
Apply function notation to answer the following questions about Andrew's wages.
Part D. How does the function notation in this example compare with the standard notation
Answer:
Step-by-step explanation:
For the first 30 hours, Andrew will earn 4(30) = $120. For each additional hour beyond 30 that Andrew works, he will earn 5(h - 30). Therefore, the function that gives Andrew's total wages when he works more than 30 hours is:
w = 120 + 5(h - 30).
So, if he works 35 hours, he will earn:
120 + 5(35 - 30) = 120 + 5(5) = 120 + 25 = $145.
If he works 42 hours, he will earn:
120 + 5(42 - 30) = 120 + 5(12) = 120 + 60 = $180.

What is the area of this regular pentagon that has been divided into five congruent triangles?
48 [tex]cm^{2}[/tex]
120 [tex]cm^{2}[/tex]
100 [tex]cm^{2}[/tex]
24 [tex]cm^{2}[/tex]
Answer:
120 cm^2.
Step-by-step explanation:
The area of one triangle = 1/2 * base * height
= 1/2 * 8 * 6
= 1/2 * 48
= 24 cm^2
So area of the pentagon = 5 * 24
= 120 cm^2.

The upper-left coordinates on a rectangle are (-6,0)(−6,0)left parenthesis, minus, 6, comma, 0, right parenthesis, and the upper-right coordinates are (-4,0)(−4,0)left parenthesis, minus, 4, comma, 0, right parenthesis. The rectangle has an area of 121212 square units. Draw the rectangle on the coordinate plane below.
Answer:
See attachment for rectangle
Step-by-step explanation:
Given
[tex]A = (-6,0)[/tex]
[tex]B = (-4,0)[/tex]
[tex]Area = 12[/tex]
Required
Draw the rectangle
First, we calculate the distance between A and B using distance formula;
[tex]AB = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
So, we have:
[tex]AB = \sqrt{(-6 - -4)^2 + (0- 0)^2}[/tex]
[tex]AB = \sqrt{(-2)^2 + (0)^2}[/tex]
[tex]AB = \sqrt{4 + 0}[/tex]
[tex]AB = \sqrt{4}[/tex]
[tex]AB = 2[/tex]
The above represents the length of the triangle.
Next, calculate the width using:
[tex]Length * Width = Area[/tex]
[tex]2* Width = 12[/tex]
Divide both sides by 2
[tex]Width = 6[/tex]
This implies that, the width of the rectangle is 6 units.
We have:
[tex]A = (-6,0)[/tex]
[tex]B = (-4,0)[/tex]
Since A and B are at the upper left and right, then the ther two points are below.
6 units below each of the above point are:
[tex]C = (-6,0-6)\\[/tex] => [tex]C = (-6,-6)[/tex]
[tex]D = (-4,0-6)[/tex] => [tex]D = (-4,-6)[/tex]
Hence, the points of the rectangle are:
[tex]A = (-6,0)[/tex]
[tex]B = (-4,0)[/tex]
[tex]C = (-6,-6)[/tex]
[tex]D = (-4,-6)[/tex]

Write an equation of the line that passes through (2,-5) and is parallel to the line 2y = 3x + 10
Answer:
y=3x/2 -8
Step-by-step explanation:
2y/2 = 3x/2 + 10/2
y = 3x/2 +5
(y-(-5)) = 3/2 (x-2)
y+5 = 3x/2 - 3
y= 3x/2 - 8

a bill is 45.89 what would your sales tax be at 6.625
Answer:
3.04
Step-by-step explanation:
The sales tax rate is either 6.625% or 0.06625 as a decimal fraction.
To calculate the sales tax on this bill, multiply 45.89 by 0.06625: 3.04
The tax would be 3.04.

Five and one fourth - One Eighth
(Math suck :( )
Answer:
Exact form: 41/8
Decimal form: 5.125
Mixed number form: 5 1/8
Explain:
First, you subtract the whole numbers
5-0: 5
Then you combine the fractions
1/4 - 1/8 = 1/8
Then add the whole number back
5 + 1/8 = 5 1/8
