Answer:
A.) 34 = 10 + 4x
Step-by-step explanation:
This equation would mean the customer rented one bike ($10) plus the hours they had it ($4 per hour) for x hours.
That means the equation would look like this 10 + 4x = 34
Find m so that ( −5 )ᵐ⁺¹ x (−5 )³ = (−5 )⁶
m-2
( −5 )2⁺¹ x (−5 )³ = (−5 )⁶
( −5 )3 x (−5 )³ = (−5 )⁶
There is a rule in exponent when multiplying,if the base is same add the exponent so 3+3 equals to 6
so the answer is
( −5 )3x (−5 )³ = (−5 )⁶

whats greater .12 or 12/16
Answer:
12/16 is greater than 0.12.
Step-by-step explanation:
0.12 = 12/100 = 6/50 = 3/25
12/16 = 3/4.
So, 12/16 is greater than 0.12.
Answer:
12/16 is greater than
12/16 as a decimal would be .75 so its greater than .12
A quadratic equation has a
discriminant equal to 5. What
does this tell you about the
solution(s) to the equation?
Answer:
[tex]\boxed {\boxed {\sf 2 \ real \ solutions }}[/tex]
Step-by-step explanation:
The quadratic formula is:
[tex]{x = \frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}}[/tex]
The discriminant of a quadratic is just the expression under the square root, or [tex]b^2-4ac[/tex]. This can tell us the number of solutions a quadratic has.
If the discriminant is:
Positive = 2 real solutions Equal to Zero = 1 real double/repeated solution Negative = 0 real solutions, but 2 imaginary solutionsOur quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.

write an equation for the line that passes through the points (-1,-12) and (4,8)
Answer:
y = 4x - 8
Step-by-step explanation:
(-1, -12) & (4, 8)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(8 - (-12)) / (4 - (-1))
Simplify the parentheses.
= (8 + 12) / (4 + 1)
= (20) / (5)
Simplify the fraction.
20/5
= 4
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 4x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (4, 8). Plug in the x and y values into the x and y of the standard equation.
8 = 4(4) + b
To find b, multiply the slope and the input of x(4)
8 = 16 + b
Now, subtract 16 from both sides to isolate b.
-8 = b
Plug this into your standard equation.
y = 4x - 8
This is your equation.
Check this by plugging in the other point you have not checked yet (-1, -12).
y = 4x - 8
-12 = 4(-1) - 8
-12 = -4 - 8
- 12 = -12
Your equation is correct.
Hope this helps!

A road roller with a 55-inch
diameter is traveling at
3 miles per hour. How many
revolutions per minute is
the roller turning? Round
your answer to the
nearest tenth
Answer:
18.34times
Step-by-step explanation:
the explanation is given in the pictures...
The road roller is turning at the rate of [tex]18.3rev/minute[/tex]
To get our answer, first note that
[tex]speed=\dfrac{distance}{time}[/tex]
since the distance travelled by the road roller can be gotten by
[tex]distance= circumference\times revolutions[/tex]
our speed formula can be expressed as
[tex]speed=\dfrac{circumference\times revolutions}{time}[/tex]
making the number of revolutions the subject of the formula, we get
[tex]revolutions=\dfrac{speed \times time}{circumference}[/tex]
carrying out the following substitutions
[tex]speed=3miles/hour=\frac{3\times63360}{60}inches/minute=3168inches/minute\\time=1minute\\circumference=2\times3.14\times\frac{55}{2}=172.7inches[/tex]
we can now calculate the number of revolutions
[tex]revolutions=\dfrac{speed\times time}{circumference}\\\\=\dfrac{3168\times 1}{172.7}\approx18.3rev/minute\text{ (to the nearest tenth)}\\\\[/tex]

Answer:
Figure 3: 28.5 units²
Figure 4: 33 units²
Figure 5: 25 units²
Figure 6: 30 units²
Figure 7: 25 units²
Figure 8: 32 units²
Reasons:
Figure 3 consists of 2 shapes, A rectangle and a square
████████ ◣
rectangle: ████████ triangle: █◣
████████ ██◣
rectangle:
to calculate a rectangle's area: multiply the lengths of the width and height:
████████= width 8 █
█ =height 3
█
[tex]area=w(h)[/tex]
now substitute the values of W and H:
[tex]8(3)=24[/tex]
rectangle area = 24
Triangle:
to find the area of a triangle, multiply the width and height and divide by two:
◣ + ◣ = █ 0.5 + 0.5 = 1
█
███=width 3 █ =height 3
█
[tex]area=\frac{w(h)}{2}[/tex]
now substitute W and H
[tex]area=\frac{3(3)}{2}[/tex]
[tex]area\frac{9}{2}[/tex]
Triangle area: 4.5
Now add the Rectangle Area To the triangle Area:
4.5 + 24 = 28.5
Final answer:
AREA =2 8.5

for every 5 red cars there are 8 black cars. If there are 24 more black cars than red cars how many total vehicles are there
Answer:
15 red cars + 24 black cars = 38
The total vehicles are 104.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
For every 5 red cars there are 8 black cars.
And, There are 24 more black cars than red cars.
Here, For every 5 red cars there are 8 black cars.
Hence, Number of red cars = 5x
Then, Number of red cars = 8x
And, There are 24 more black cars than red cars.
Hence, We get;
⇒ 24 + 5x = 8x
Solve for x as;
⇒ 24 = 8x - 5x
⇒ 24 = 3x
⇒ x = 8
Thus, Number of total vehicles = 5x + 8x
= 5×8 + 8×8
= 40 + 64
= 104

An electrician bought 120 feet of electrical wire and used 105 feet of it
What percent of the wire went unused?
A 15%
B 12.5%
C 8.75%
D 7%
Answer:
B. 12.5%
Step-by-step explanation:
Find how much was unused:
120 - 105
= 15
To find what percent this is, divide it by 120:
15/120
= 0.125
Multiply this by 100:
0.125(100)
= 12.5
So, 12.5% of the wire went unused
The correct answer is B. 12.5%
