Answer:
m= 4Step-by-step explanation:
(-5)^(m + 3) × (-5)^8 = (-5)^15(-5)^(m + 3 + 8) = (-5)^15(-5)^(m + 11) = (-5)^15m + 11 = 15m = 4A factory produces 60 candy bars in 5 minutes. If the factory continues producing at the same rate. How many candy bars does it produce in 10 minutes, 1 minute, 7 minutes
Answer:
10 minutes would be 120 candy bars.
1 minute would be 12 candy bars.
7 minutes would be 84 candy bars.
Step-by-step explanation:
For 10 minutes you multiply 60 times 2, which would be 120 candy bars.
For 1 minute you divide 60 by 5, which would be 12 candy bars.
For 7 minutes you would add 60 and 24, which would be 84 candy bars.

A parabola can be drawn given a focus of (4, -3) and a directrix of y=5 Write the equation of the parabola in any form.
Answer:
The equation of the parabola is (x - 4)² = -16(y - 1)
Step-by-step explanation:
The standard form of the equation of the parabola is (x - h)² = 4p(y - k), where
The vertex of the parabola is (h, k)The focus is (h, k + p)The directrix is at y = k - p∵ The focus of the parabola is (4, -3)
∵ The focus is (h, k + p)
∴ h = 4
∴ k + p = -3 ⇒ (1)
∵ It has a directrix of y = 5
∵ The directrix of the parabola is y = k - p
∴ k - p = 5 ⇒ (2)
→ Add equations (1) and (2) to find k and p
∵ (k + k) + (p - p) = (-3 + 5)
∴ 2k + 0 = 2
∴ 2k = 2
→ Divide both sides by 2
∴ k = 1
→ Substitute the value of k in equation (1)
∵ 1 + p = -3
→ Subtract 1 from both sides
∴ 1 - 1 + p = -3 - 1
∴ p = -4
∵ The form of the equation of the parabola is (x - h)² = 4p(y - k)
→ Substitute the values of h, k, p in it
∴ (x - 4)² = 4(-4)(y - 1)
∴ (x - 4)² = -16(y - 1)
∴ The equation of the parabola is (x - 4)² = -16(y - 1)

Jada says she can find 87-59 by taking away 60 and adding 1 so it is the same as 27+1 or 28. Explain why jadas method to calculate 87-59 makes sense.
Answer:
The correct answer is 28.
Step-by-step explanation:
Actually Jada makes problem simpler by adding and subtracting 1
that is
87 ₋ 59 ₋1 ₊ 1
so there would be no effect on our final answer because we have added 1 and also subtracted 1
Now,
87 - 59 -1 + 1
87 - 60 +1 ( ∵ -59 - 1 = -60 )
27 + 1 (∵ 87 - 60 = 27 )
28
so the final answer is 28 .
Mai's family drink a total of 10 gallons of milk every 6 weeks. How many weeks does it take the family to consume 3 gallons of milk?
Answer:
1.8 weeks
Step-by-step explanation:
The number of weeks it takes for consuming the 3 gallons of milk is as follows:
It is given that the total of 10 gallons of milk drink for every 6 week i.e. 5 by 3
Now in order to determine the weeks we have to reciprocal the ratio i.e. 3 by 5
Now for 3 gallons it would be
[tex]= \frac{3}{5}\times 3[/tex]
= 1.8 weeks

PLZ HELP ASAP DUE TODAY!
Answer:
5(9x + 2y + 10)
or
x = 0
y = -5
Step-by-step explanation:
If you are just factoring this, you will factor a 5 out from everything.
5(9x + 2y + 10)
or if you are trying to solve just isolate one of the variables and then substitute it into the original equation
45x + 10y = 50
10y = 50 - 45x
y = 5 - 4.5x
45x + 10(5-4.5x) + 50
45x + 50 - 45x + 50
x=0
45(0) + 10y + 50
0 + 10y + 50
10y + 50
10y = -50
y = -5
and it would be x = 0 and y = -5

You bought a book for $10 and 5 pens. You spent a total of $40. How much did each pen
cost?
Answer:
Each pen costs $6
Step-by-step explanation: $40 total -$10 from the book=$30 left.
$30 left divided by 5 pens = $6 each pen.
Answer: $6
Step-by-step explanation:
This is because you got a book for $10 so you would first minus 10 for the $40 you have and then you have $30 dollars left and 6 x 5 is 30 so then when you add back 10 and the 30 dollars you get the total amount of money.

Answer:
x= -1/3
Step-by-step explanation:
In the picture attached. if still doubting the answer, check by Substituing the value of x in the equation given.
The required solution to the given equation -3.1x + 7 - 7.4x = 1.5x - 6(x -3/2) is x = -1/3.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question:
-3.1x + 7 - 7.4x = 1.5x - 6(x -3/2)
Apply the distributive property of multiplication,
-3.1x + 7 - 7.4x = 1.5x - 6x -3 × -3
-3.1x + 7 - 7.4x = 1.5x - 6x + 9
Rearrange the like-wise terms and apply the arithmetic operation,
-3.1x - 1.5x + 6x - 7.4x = -7 + 9
-6x = 2
x = -2/6
Apply the division operation,
x = -1/3
Thus, the required solution to the given equation -3.1x + 7 - 7.4x = 1.5x - 6(x -3/2) is x = -1/3.

y + 2 = 2/3 (x - 4)
Slope
Answer: Y = 2/3x - 14/3
Answer:
2/3
Step-by-step explanation:
y+2=2/3 (x-4)
1. multiply parentheses (y+2=2/3x-8/3
2. subtract 2 from both sides (y=2/3x-2/3
3. 2/3x is the slope
What is the value for y?
Answer:
Isosceles triangle basically has two equal sides and angles opposite to these equal sides are also equal.Therefore
50° = 2x°
50/2 = x
25 = x
There fore value of x is 25.
so,angle B = 2 × 25
hence angle B is 50

What is the volume of a hemisphere with a diameter of 9.9 cm, rounded to the nearest tenth of a cubic centimeter?
9514 1404 393
Answer:
254.0 cm³
Step-by-step explanation:
The formula for the volume of a sphere in terms of its radius is ...
V = (4/3)πr³
Then the formula for the volume of a hemisphere in terms of its diameter is ...
V = (1/2)(4/3)π(d/2)³ = (π/12)d³
The volume of the hemisphere is ...
V = (π/12)(9.9 cm)³ ≈ 254.024 cm³
The volume is about 254.0 cm³.

Answer: x= 3
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
So the equation is 90=12x+54. You get x by itself. To do that you subtract 54 from 90. You get 36. Then you divide.
