The cost to rent a moving truck is a flat fee of $25 plus $0.60 per mile. The equatic
c, in dollars for the number of miles, m, traveled in the truck.
Identify the independent and dependent variables.
The
is the independent variable.
The
is the dependent variable.
$25 flat fee
cost
miles traveled?
Answer:
See explanation below
Step-by-step explanation:
Flat fee = $25
Cost per mile = $0.60
Let
C = total cost
m = number of miles travelled by the truck
The equation is
C = 25 + 0.60m
The independent variable is miles,m travelled
The dependent variable is total cost, C
$25 is the constant
(2a divided by 7) - (a-4)
Answer:
a=28/5 or 5.6
Step-by-step explanation:
2a/7=a-4
Multiple both sides of the equation by 7
2a=7a-28
Subtract 7a from both side
2a-7a=-28
Like Term
-5a=-26
Divide -5 from both side
a= 5.6
Find the volume of the prism. 5 cm 13 cm 13 cm
just need number 5 !
Answer:
6.5
Step-by-step explanation:
Cos = Adjacent/Hypotenuse
For the angle with the measure of 70°
Adjacent = x
Hypotenuse = 19
Hence, cos 70 = x/19
multiply both sides by 19
cos(70) * 19 = 19cos(70)
x/19 * 19 = x
we're left with x = 19cos(70)
19cos(70) = 6.5 ( rounded to the nearest tenth )
x = 6.5

Answer:
y = 0
Step-by-step explanation:
Let's use the addition method.
2x + y - 10 = 0
x - y - 5 = 0
Write the first equation as is. Write below it the second equation multiplied by -2 on both sides. Then add the equations.
2x + y - 10 = 0
(+) -2x + 2y + 10 = 0
--------------------------------
3y = 0
Divide both sides by 3.
y = 0
Answer: y = 0
Selma uses a jogging trail that runs through a park near her home. The trail is a loop that is of a mile long. On Monday, Selma ran the loop in of an hour. What is Selma's unit rate in miles per hour for Monday's run?
Answer:
4.5 miles per hour
Step-by-step explanation:
Selma uses a jogging trail that runs through a park near her home. The trail is a loop that is 3/4 of a mile long. On Monday, Selma ran the loop in 1/6 of an hour. What is Selma's unit rate in miles per hour for Monday's run?
Distance = 3/4 of a mile
Time taken on Monday = 1/6 of an hour.
What is Selma's unit rate in miles per hour for Monday's run?
Unit rate in miles per hour for Monday's run = distance ÷ time taken
= 3/4 ÷ 1/6
= 3/4 × 6/1
= (3 * 6) / (4 * 1)
= 18/4
= 4.5 miles per hour
Unit rate in miles per hour for Monday's run = 4.5 miles per hour

Your adjacent is 3, your opposite is 4, and you have a 90 degree angle. Find the value of cos V rounded to the nearest hundredth, if necessary.
Answer:
0.6 or [tex]\frac{3}{5}[/tex]
Step-by-step explanation:
Using the Pythagorean theorem ([tex]a^{2} +b^{2} =c^{2}[/tex]) we get that the hypotenuse is 5.
so the cos V is adjacent over the hypotenuse. so if adjacent is 3 and hypotenuse is 5, the answer is [tex]\frac{3}{5}[/tex] which equals 0.6 in decimal form.

Answer:
4th option 0,5,10,15
Step-by-step explanation:
Let's check if the first choice is geometric.
2*3 = 6. is 6*3 = 18, yes! is 18*3 = 54. Yep! its geometric
the second option multiplies by -2, it is geometric
the third option multiplies by 1/5, it is geometric
The fourth option does not multiply by anything common, it is Not geometric
Answer:
0,5,10,15 is not the sequence of geometric.
Generally, to check whether a given sequence is geometric, one simply checks whether successive entries in the sequence all have the same ratio. The common ratio of a geometric series may be negative, resulting in an alternating sequence.

What is the translation shown in the graph?
Answer:
The shape is translated four units left, and 2 units up, therefore the answer would be x=-4 and y=+2
Answer:
P= (1,-1)= P'= (-3,1)
T=(4,-1)=T'= (0,1)
R=(5,1)=R'= (1,3)
A= (5,3)=A'= (1,5)
So you would move the points 4 units across (left) and 2 units up (2,-4)
I would think your answer is right, it would be the second choice. Its just a little hard to determine because you would use the method of moving the point but to double check you would use one of the points, for example (1,-1) you would do 1+2-4 to see if you would get -3 and do the same with -1, -1+2-4. I hoped this helped!

x(2a+b) -3y(2a+b)
(2a+b) (x-3y)
Answer:
Step-by-step explanation:
2ax -6ay +bx -3by
take common from first two terms and take common from third and fourth term
=2a(x-3y)+b(x-3y)
take common (x-3y) is common
=(x-3y)(2a*1+b*1)

You are thinking of buying a new tent. Look at the dimensions given below.
What is the perimeter of the tent's porch?.
Answer:
Step-by-step explanation:
The shorter sides of the porch can be found by subtracting 2.5m from 3m to get .5m; the longer sides are found by looking at the opposite end of the tent at the rectangle with a 1 inside of it. That 1 indicates the length of the rectangle, which is the same for the porch's length. That means that the perimeter is .5+1+.5+1 which is 3m total.

7.8 is what percent of 78?
Answer:
10 %
Step-by-step explanation:
let the percent be x
according to the question
7.8 = x % 0f 78
7.8 = x /100 * 78
7.8*100 = 78x
780 = 78x
780/78 = x
10 = x
Answer:
10 percent
Step-by-step explanation:
7.8 is ? of the number 78.
So, we will multiply 7.8 by 100.
7.8 x 100 = 780
Now, we will divide 780 by 78.
780/78 = 10
So, our answer is 10.
Or, you can divide:
78 divided by 7.8 is 10
which is the best estimate for the percentage equivalent of 7/15

Answer:
a. x= 9
b. 70
c. 110
d. 70
e. 110
Step-by-step explanation:
a.
congruent angles have the same measure. 1 and 3 are congruent and 2 and 4 are congruent
2(12x+2)+2(7x+7)=360
divide both sides by 2
12x+2+7x+7=180
combine like terms
2+7=9
12x+7x=19x
19x+9=180
subtract both sides by 9
19x=171
divide both sides by 19
x=9
7x+7,
7*9+7
63+7 = 70
1 is 70, 3 is 70
12x+2, x=9
108+2 = 110
2 and 4 is 110
Answer:
Step-by-step explanation:
Angles 1 and 2 are supplementary (their sum is 180 degrees)
7x + 7 + 12x + 2 = 180
19x= 171
x = 9
m 1 = 7 * 9 + 7 = 70 degrees
m 2 = 12 * 9 + 2 = 108 + 2 = 110 degrees
m 3 = angle 1 and angle 3 are vertical, so they have the same measure: 70 degrees.
m 4 = angle 2 and angle 4 have the same measure: 110 degrees
State one obtuse angle and one acute angle
Answer:
obtuse angle is 2 and acute angle is 1
Step-by-step explanation:
Obtuse Angle: An angle between 90 and 180 so angle 2 is an obtuse angle
Acute Angle: An angle between 0 and 90 so angle 1 is an acute angle
What could be the coordinates of the third vertex, z, of triangle xyz so that it would have a hypotenuse with a length of square root 45 units
Answer:
[tex]z = (6,-1)[/tex]
Step-by-step explanation:
The missing parameters are:
[tex]x = (3,-1)[/tex]
[tex]y = (3,5)[/tex]
[tex]yz= \sqrt{45[/tex] --- Hypotenuse
Required
The coordinate of Z
First, calculate the distance xy
[tex]xy = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
[tex]xy = \sqrt{(3 - 3)^2 + (-1 - 5)^2}[/tex]
[tex]xy = \sqrt{0 + 36}[/tex]
[tex]xy = \sqrt{36}[/tex]
[tex]xy = 6[/tex]
By Pythagoras theorem, distance xz is:
[tex]yz^2 = xz^2 + xy^2[/tex]
[tex](\sqrt 45)^2 = xz^2 + 6^2[/tex]
[tex]45 = xz^2 + 36[/tex]
Collect like terms
[tex]xz^2 =45-36[/tex]
[tex]xz^2 =9[/tex]
[tex]xz = \sqrt{9}[/tex]
[tex]xz = 3[/tex]
This means that z is 3 units to the right of x
We have:
[tex]x = (3,-1)[/tex]
The rule to determine z is:
[tex](x,y) \to (x + 3, y)[/tex]
So, we have:
[tex]z = (3 + 3,-1)[/tex]
[tex]z = (6,-1)[/tex]
