Answer:
42mph.
Step-by-step explanation:
We know that the formula for miles per hour is.
r = d/t
R is our rate or miles per hour.
D is our distance.
T is our time.
In this case our distance is 105 miles.
And our times is 2.5 hours.
Therefore if we substitute them into our formula:
105mi ÷ 2.5hrs = 42mph

Answer: (x-6)(x+1)
Step-by-step explanation:
Sum : x2 − 5 x- 6
x2 + x-=6 x − 6
factor pair: x 2 + x − 6 x − 6
x( x+ 1 ) − 6 ( x + 1 )
rewrite from: x (x + 1 ) − 6 ( x + 1 )
(x-6)(x+1)
Answer:
A: (x-6)(x+1)
Step-by-step explanation:
We need to find 2 numbers that add to make -5 and multiply to make -6.
We already have the numbers infront of us, so by process of elimination we can remove B and D.
For the numbers, we need a positive number and a negative number (two negatives make a positive). We can eliminate C because at first -3 multiplied by 2 is -6. However, when -3 is added to 2 we get -1.
If we expand A, it makes the expression that needs to be factorised because...
-6 × 1 = -6
-6 + 1 = -5
So expanding it properly we get.
x² - 6x + x - 6
Simplify.
x² - 5x -6

Will a fraction increase or decrease and by what percent if its numerator is increased by 20% and its denominator is increased by 50%?
The fraction will increase or decrease by what percent
Answer:
increase by the percent
The fraction will decrease by 20%.
What is Fraction?A fraction represents a part of a whole.
Let's assume the original fraction to be x/y.
If we increase the numerator by 20%, it becomes 1.2x.
If we increase the denominator by 50%, it becomes 1.5y.
So, the new fraction will be:
(1.2x) / (1.5y)
Simplifying this expression, we get:
(4x/5y)
The new fraction is (4/5) times the original fraction.
Therefore, the fraction will decrease by 20%.

Find the volume of the prism. Round your answer to the nearest tenth.
for brainlist
Answer:
d. V = 668.2 ft³
Step-by-step explanation:
[tex]V = \frac{1}{2}bhl\\V = \frac{1}{2}(8.6)(8.4)(18.5)\\V = 668.2ft^{3}[/tex]
Answer:
[tex]\boxed {\boxed {\sf D. \ V \approx 668.2 \ ft^3}}[/tex]
Step-by-step explanation:
The volume of a triangular prism is found using this formula:
[tex]V=\frac{1}{2} bhl[/tex]
For this prism, the base is 8.6 feet, the height is 8.4 feet, and the length is 18.5 feet.
[tex]b= 8.6 \ ft \\h= 8.4 \ ft \\l= 18.5 \ ft[/tex]
Substitute the values into the formula.
[tex]V= \frac{1}{2} (8.6 \ ft) (8.4 \ ft) ( 18.5 \ ft)[/tex]
Multiply the first two numbers in parentheses.
[tex]V= \frac{1}{2} (72.24 \ ft^2) ( 18.5 \ ft)[/tex]
Multiply again.
[tex]V= \frac{ 1}{2} (1336.44 \ ft^3)[/tex]
Multiply by 1/2 or divide by 2.
[tex]V= 668.22 \ ft^3[/tex]
Round to the nearest tenth. The 2 in the hundredth place tells us to leave the 2 in the tenth place.
[tex]V \approx 668.2 \ ft^3[/tex]
The volume is about 668.2 cubic feet.

Determine whether the system of equations has one solution, no solution, or infinitely many solutions. 4x=10+4y and 2x-2y=15
Answer:
infinitely many solutions
Step-by-step explanation:
Given the simultaneous equation
4x=10+4y... 1
2x-2y=15 .... 2
_____________
4x-4y = 10 * 1
2x-2y = 15 * 2
__________--
4x-4y = 10
4x-4y = 30
Add both equation
8x - 8y = 10+30
8x-8y = 40
Divide though by 8
x-y = 5
x = 5 + y
Since the result gave 1 equation and 2 unknowns, then we will let x =k
k = 5 + y
y = k -5
k can be any integer
(x,y) = (k, k-5)
This show that the equation has infinitely many solutions
solve the equation -16(d+1) =-20
Answer:
d= 1/ 4
Step-by-step explanation:
Answer: 1/4
Step-by-step explanation:
-16(d + 1) = -20
-16d - 16 = -20
-16d - 16 + 16 = -20 + 16
-16d = -4
-16d/-16 = -4/-16
d = 1/4
A movie theater sells out 7 times per month. Chloe counted 168 sellouts at the theater. How long was Chloe recording sales?
A. 7 years
B. 2 years
C. 1 year
D. 24 years
More questions will be asked in the comments
Answer:
B. 2 years
Step-by-step explanation:
use y = mx + b
y = total number of sell outs = 168
m = sell outs per month = 7
x = months
b is not needed for this
168 = 7x
divide both sides by 7
x = 24
divide 24 by 12 to get the number of years
years = 2
Answer:
the answer to this question is B. 2 years

If 500 calories adds 1 pound to your weight how many 1000 calorie banana splits would you need to eat to gain 10 pounds
Answer: 5
Step-by-step explanation:
each banana split is equal to 2 lbs. therefore, to gain 10 lbs. you need to eat 5 banana splits.
500cal = 1 lb.
1000cal = 1 banana split
1 banana split = 2lbs.
to gain 10lbs, divide 10lbs by 2lbs = 5 banana splits

m∠ACD = 68°
Step-by-step explanation:
∠BAE ≅∠DAC because they are vertical angles
∠ACD = 180 - 124 = 56°
to find 'x': 56 + 2x + (180 - 4x) = 180
236 - 2x = 180
-2x = -56
x = 28
m∠ACD = 180 - 4(28) = 180 - 112 = 68°
The terms in the sequence decrease by the same amount each time:
9, 6 ,3 ,0, -3, -6
Work out ,in term of n, the nth term of the sequence
Answer:the nth term of the sequence, Tn= -3n +12
Step-by-step explanation:
The nth term of an arithmetic progression is given as
Tn= a+ (n-1) d
where a= first term
and d = common difference
In this sequence, 9, 6 ,3 ,0, -3, -6 we can see that the number is decreasing by 3
The first term, a= 9
and common difference, d = -3
using our formulae
Tn= a+ (n-1) d
Tn= 9 + ( n-1) -3
Tn=9- 3n+ 3
Tn= -3n +12

Given that a = ( − 6 7 ) and b = ( − 1 − 3 ) . If a − b = ( x y ) , work out the values of x and y .
Answer:
x = -5 , y = 10
Step-by-step explanation:
As given ,
a = ( x₁ , y₁ ) = ( -6, 7)
b = ( x₂ , y₂ ) = (-1, -3)
For a -b = ( x₁ - x₂ , y₁ - y₂ )
= ( -6 - (-1) , 7 - (-3) )
= ( -6 + 1 , 7 + 3 )
= ( -5 , 10 )
⇒ a - b = ( -5, 10 ) = ( x, y)
∴ we get
x = -5 , y = 10
