Answer:
i think it would be 2 because its in the middle of the slope and it would make scence
Step-by-step explanation:
Decide whether n = 9 is a solution to
the equation 2+n=7. Write yes or no
Answer:
No. The answer would be n=5
Step-by-step explanation:
You have to subtract the 2 from both sides to cancel it out on the left side. so you would be doing 7-2, not 7+2
Patrick drank 3/4 liter of water Monday before jogging. He drank 4/5 liter of water after his jog. How much water did Patrick drink altogether? (Write fraction answers as a mixed number like this 2 1/2) He drank _____ liters. *
Answer: 1¹¹/₂₀ litres
Step-by-step explanation:
The fractions need to be added.
Find a common multiple for them.
Common multiple = 20
Divide the multiple by the denominator of the fraction and multiply the numerator by the result you get:
[tex]= \frac{15 + 16}{20} \\\\= \frac{31}{20} \\\\= 1\frac{11}{20}[/tex]
= 1¹¹/₂₀ litres
What happens when a figure is dilated .
Answer:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. A dilation that creates a larger image is called an enlargement. A dilation that creates a smaller image is called a reduction. A dilation stretches or shrinks the original figure.

A total of $5000 is invested part of 6% and the remainder at 12% how much is invested at each rate if the annual interest is $480
Answer:
for 12% it would be $3,000
And, for 6% it would be $2,000
Step-by-step explanation:
The computation of the amount invested at each rate is shown below:
Let us assume the amount invested at 12% be x
So, the $5,000 - x be invested at 6%
The total interest earned is $480
So the equation would be
0.12x + 0.06($5,000 - x) = $480
0.12x + $300 - 0.06x = $480
0.06x = $80
x = $3,000
So for 12% it would be $3,000
And, for 6% it would be $2,000
what is the length of line segment FH?
a cone has a height of 4 ft and a volume of 7.77 Ft cubed determine its radius to the nearest tenth of a foot
Answer:
The radius of the cone is approximately 1.4 feet
Step-by-step explanation:
The given parameters of the cone are;
The height of the cone, h = 4 ft.
The volume of the cone, V = 7.77 ft.³
The volume, 'V', of a cone is given by the following formula;
V = 1/3 × π·r²·h
Where;
V = The volume of the cone = 7.77 ft.³
r = The radius of the cone
h = The height of the cone = 4 ft.
By substituting the vales of 'h' and 'V' in the above equation, we have;
7.77 ft.³ = 1/3 × π × r² × 4 ft.
∴ r = √(3 × 7.77 ft.³/(π × 4 ft.)) = 1.36196580784 ft.
∴ The radius of the cone, r ≈ 1.4 ft. (rounding the answer to the nearest 10th)

y > 5X-7 solid or dotted line
Answer:
Dotted line
Step-by-step explanation:
when using the > or < symbols you put a dotted line because the line is not included in the shaded area.
If the symbols were a < or a > you would put a solid line.
2. Solve x - 19 <81. Then graph the solution.
Answer:
x<100
Step-by-step explanation:
The given equation is :
x-19<81
Adding 19 to both sides of the equation.
x-19+19<81+19
x<100
It means the solution of the given equation is less than 100. Hence, the attached figure shows the graph for the given equation.
Ben has dollars. Sally has dollars less than Ben. Which expression represents the amount of money that Sally has?
Answer: m - 5
Step-by-step explanation:
Ben has m dollars.
Sally has $5 less than the amount that Ben has. This means that to find the amount of money Sally has, one needs to deduct $5 from the amount that Ben has.
Again, Ben has m. Sally's money is therefore:
= m - 5
Yanis worked at a local restaurant over break to save up for a
trip to the Dominican Republic which would cost $460. If she made $15 per hour
and she already had $100 saved, how many hours does she need to work to
make enough for her trip to DR?
Answer:
24 hours
Step-by-step explanation:
first subtract 100 from 460 to get 360, then divide 360 by 15 which equals 24.
Ty'Lil has $220 to spend on a membership to a new gym. The monthly fee is $15 and he must also pay $40 to join. How many months can he afford?
Answer: 12
Step-by-step explanation:
220-40=180
180/15=12
Answer:
11 months
Step-by-step explanation:
220 -40=180
Since you have to pay $40 to join you have to add $15 to that $40 for the monthly fee.
220-40-15=156
^ This equals one month worth of the membership.
220-40-15-15-15-15-15-15-15-15-15-15-15=0
So add up all the 15s and you have the number of months Ty ´Lil can afford.
I hope this makes sense.

Solving Square root and other radical equations
Answer: How to answer radical questions and such:
The most basic is to isolate one of the square roots, square both sides, and this will usually yield less square roots than when you started with. Keep repeating until you have no more square roots. This works pretty well in most cases, there are sometimes some tricks, arising from the particular problems themselves ways, which allow you to solve the equations much faster
The solving methods for Square root and radical equations are given below.
What is a radical equation?An equation wherein a variable is withinside the radicand of a thorough expression is referred to as a thorough equation. As usual, whilst fixing those equations, what we do to at least one aspect of an equation we ought to do to the alternative aspect as well. Once we isolate the radical, our approach could be to elevate each facet of the equation to the strength of the index. This will remove the radical.

Para fabricar un DVD del modelo A se utiliza 1 kilogramo de caucho y 1 horas de trabajo, y para fabricar un DVD del modelo B se utiliza 1 kilogramo de caucho y 2 hora de trabajo. Si la venta le genera una utilidad 30 soles por cada modelo A y 40 soles por cada modelo B. ¿Cuántos DVD de cada tipo debe fabricar y vender para que la utilidad sea máxima?
Answer:
¿Cuántos DVD de cada tipo debe fabricar y vender para que la utilidad sea máxima?
Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800
Step-by-step explanation:

MODELO A MODELO B TOTAL
Cantidad de caucho 1x 1x 50 kg.
Horas de mano de obra 1x 2x 80 horas
U : Utilidad mensual.
La función objetivo, que se debe maximizar, es:

U (0, 0) = 30 (0) + 40 (0) = 0
U (50, 0) = 30 (50) + 40(0) = 1500
U (90, 0) = 30 (20) + 40 (30) = 1800
U (0, 40) = 30 (0) + 40 (40) =1600
Por consiguiente U tiene un valor máximo en C , en donde: x =20 , y = 30 .
