Answer:
5 dozen Donuts
7 dozen bagels
Step-by-step explanation:
5 * 9 = 45
7 * 8 = 56
56 + 45 = 101
Answer: He bought 5 dozen donuts
Step-by-step explanation:
d + b = 12 where d is the number of donuts and b is the number of bagels.
9d + 8b= 101 now solve the two equations using the elimination method
-9d - 9b =-108
9d + 8b = 101
-1b = -7
b = 7
9d + 8(7)= 101
9d + 57 = 101
9d = 45
d= 5

hacer paquetes de 6 libretas y paquetes de 6 lápices de co-
ores, los maestros de una escuela se percataron de que habla
mas paquetes de lápices que de libretas, y de que en ambos
casos no sobraba nada. Se sabe que la cantidad original de
bretas está entre 185 y 190, y la de lápices, entre 220 y 225.
¿Cuál será la cantidad original de libretas y lápices de colores?
y
Answer:
186 notebooks; 222 pencils
Step-by-step explanation:
1. Notebooks
The number of notebooks must be between 185 and 190.
To have no notebooks left over, the number of 6-packs must be an integral multiple of six.
The only integral multiple of six between 185 and 190 is 186.
186÷ 6 = 31
So, there are 31 packs containing a total of 186 notebooks.
2. Pencils
The number of pencils must be between 220 and 225.
To have no pencils left over, the number of 6-packs must be an integral multiple of six.
The only integral multiple of six between 220 and 225 is 222.
222÷ 6 = 37
So, there are 37 packs containing a total of 222 pencils.
There were originally 186 notebooks and 222 pencils.

A member of the local department of transportation recorded the number of passengers that arrived on flights at the airport based on the month of the year. Some of her data is in the table, where month 1 is January, month 2 is February, and so on.
Month Passengers
1 3,771
2 3,814
5 3,890
7 3,889
10 3,881
If the curve of best fit for the data is y = -5x2 + 60x + 3,715, which is the best prediction of the number of passengers that arrived on flights in April?
A.
3,875
B.
3,895
C.
3,915
D.
5,823
Answer:
The correct option is A,3875 passengers
Step-by-step explanation:
The curve of best fit for the date y=-5x^2+60x+3715
For April which month 4 which means that x is 4
By substituting 4 for x in the equation we can determine y, the number of passengers that arrived on flights at the airport is determined thus.
y=-5*4^2+(60*4)+3715
y=-5*16+240+3715
y=-80+240+3715=3875
The number of passengers that arrived by flights in April, month 4 is 3875
A bag contains yellow marbles and red marbles, 77 in total. The number of yellow marbles is 5 more than 3 times the number of red marbles. How many yellow marbles are there?
Answer:
41
Step-by-step explanation:
yellow marbles=5+ 3r(r is the number of red marbles)
red marbles=3r
3r+3r+5=77
6r=77-5
6r=72
r=72/6=12
yellow marbles = 5 + 3r
5+ 12 x 3
5+ 36
=41

Emily gast deposits $50,000 in a 4-year cd that earns interest at an annual rate of 5.25% compounded daily. (a) find the amount of the cd in 4-years. (b) find the interest earned in 4-years
Answer:
a) $61,607.75
b) 11.607.75
Step-by-step explanation:
Kindly check attached picture for detailed calculation
Answer:
A.) $61682.97
B.) $11,682.97
Step-by-step explanation:
Initial deposit (A) = $50000
Period(t) = 4 years
Interest(r) = 5.25% annually,
n = number of times interest is compounded
Amount of the CD in four years :
Compound interest formula :
A = final amount
A = P(1 + r/n) ^nt
A = $50,000( 1 + (0.0525/365))^365×4
A = $50,000( 1 + 0.00014383562)^1460
A = $50,000(1.00014383562)^1460
A = $50,000(1.23365943637930)
A = $61682.9718189651
B.) Interest = $61682.97 - $50,000
Interest = $11,682.97
1. The measure of angle GHI is 120° Angle GHI is cut in half with ray HK, if angle
GHK is 3x + 48what is the value of x?
Answer:
The value of x = 4
Step-by-step explanation:
In this question, we are asked to calculate the value of the angle x
Here the ray cuts the angle into half.
Since the total of the angle was 120, half of this would be 120/2 = 60
Now, it is this value of 60, that our new angle equals to
Mathematically;
3x + 48 = 60
3x = 60-48
3x = 12
x = 12/3
x = 4
What’s the mid point for 0.2 and 0.3
Answer: 0.25
Step-by-step explanation:
Answer:
0.25
Step-by-step explanation:
The midpoint of a number is its halfway or middle.
from 0.20-0.30 the half way would be 0.25
that's because you both either add or subtract 0.05 to get its middle
Exercise 3 A pipe discharges wine into a 1.5-m-diameter tank. Another pipe (15 cm diameter), located near the base of the tank, is used to discharge wine out of the tank. Calculate the volumetric flow rate into the tank if the wine level remains constant at 2.5 m.
Answer:
Volume flow rate, Q, into the tank is 12.376 m³
Step-by-step explanation:
Here we have Bernoulli's equation presented as follows
[tex]\frac{P_{1}}{\rho _{1}g}+\frac{v_{1}^{2}}{2g} + z_{1} = \frac{P_{2}}{\rho _{2}g}+\frac{v_{2}^{2}}{2g} + z_{2}[/tex]
Where:
P₁ = Pressure, of the open tank = Atmospheric pressure = 0
P₂ - Pressure at the discharge of the pipe = Atmospheric pressure = 0
ρ₁ = Density of the fluid = ρ₂
v₁ = Velocity of the fluid in the tank
v₂ = Velocity of the fluid in the pipe
d₁ = Diameter of the tank = 1.5 m
d₂ = Diameter of the pipe = 15 cm = 0.15 m
A₁ = Cross sectional area of tank = π×d₁²/4 = 1.767 m²
A₂ = Cross sectional area of pipe= π×d₂²/4 = 0.01767 m²
z₁ = Level of water in the tank = 0 m
z₂ = Level of water in the pipe = 2.5 m
Whereby the level remains constant at 2.5 m, pressure at the base, P₂ = ρ₁×g×2.5
Also
v₁×A₁ = v₂×A₂ which gives;
v₁×1.767 = v₂×0.01767
v₂ = v₁×1.767/0.01767 = 100·v₁
Hence we have;
[tex]\frac{0}{\rho _{1}g}+\frac{v_{1}^{2}}{2g} + z_{1} = \frac{0}{\rho _{1}g}+\frac{(100v_{1})^{2}}{2g} + z_{2}[/tex]
[tex]z_{1} - z_{2} = \frac{(100v_{1})^{2}}{2g}- \frac{v_{1}^{2}}{2g}[/tex]
[tex](2.5)2g = 99v_{1}^{2}}[/tex]
v₁² = 2.5×2×9.81 = 49.05
v₁ = √49.05 = 7.0035 m/s
Therefore, since the rate of discharge = Rate of entry into the tank, we have;
Volume flow rate, Q, into the tank = v₁×A₁ = 7.0035 m/s × 1.767 m² = 12.376 m³.

Solve for p.
–5.7p = –14.82 − 7p
Answer: p = -11.4
Step-by-step explanation: –5.7p = –14.82 − 7p
–5.7p = –14.82 + − 7p
–5.7p = -7p - 14.82
–5.7p + 7p = -7p - 14.82 + 7p
1.3p = -14.82
1.3p/1.3 = -14.82/1.3
p = -11.4

rewrite the equation in slope intercept form 7x + 9y = 9
Answer:
y = -7/9 x +1
Step-by-step explanation:
7x + 9y = 9
The slope intercept form is y = mx+b where m is the slope and b is the y intercept
Subtract 7x from each side
7x -7x+ 9y =-7x+ 9
9y = -7x+9
Divide each side by 9
9y/9 = -7/9 x +9/9
y = -7/9 x +1
The slope is -7/9 and the y intercept is 1
Answer:
[tex]y = \frac{7}{9} x + 1[/tex]
Step-by-step explanation:
[tex]7x + 9y = 9 \\ 9y = 9 - 7x \\ y = \frac{9 - 7x}{9} \\ y = \frac{7}{9} x + 1[/tex]
hope this helps

do your program and leave
Step-by-step explanation: Be their for several months (6 months-least amount of time 1 year, 3 months, and 5 days or more- most amount of time) do programming (literally everything the staff + what your therapist say or need you to do). Don't do anything to get on precautions (which includes sleeping in the common area and showering with a foot in the door). And lastly respect everyone. No need for laser-beams or hurting security just do anything and everything you need to do to leave that place and never do anything to go back b/c in the end no one belongs in a place like that. I know from experience.

A parabola intersects the X-axis at X
= 3 and x= 9.
What is the x-coordinate of the parabola's vertex?
Answer:
x = 6
Step-by-step explanation:
The vertex lies on the axis of symmetry which is situated midway between the x- intercepts, thus x- coordinate of vertex is
[tex]x_{vertex}[/tex] = [tex]\frac{3+9}{2}[/tex] = [tex]\frac{12}{2}[/tex] = 6
8. The length of the hypotenuse of a right
triangle measures 2.5 inches. If one leg
measures 1.5 inches, what is the length
of the other leg?
Answer:4
Step-by-step explanation:
The formula we want to use for this is leg^2 + leg^2 = Hypotenuse^2
Let’s make x the other leg length since that’s what we are trying to find.
So it should look like this
Equation: 1.5^2 + x^2= 2.5^2
1) lets square them
2.25 + x^2 = 6.25
2) let’s get x^2 by itself so what we will do is subtract 2.25 from both sides
X^2 = 4
3) we need to remove the exponent from x so what we would do is put a radical on 4 and since we need to get four out of the radical, we need two of the same numbers that multiply to get four with is 2 because
2x2=4
4) so ur answer would be 2
X=2
Some of the students at Kahlo Middle School like to ride their bikes to and from school. They always ride unless it rains.Let d be the distance in miles from a student's home to the school. Write two different expressions that represent how far a student travels by bike in a four week period if there is one rainy day each week.
Answer:
1. d(4)(4) = 16d
Step-by-step explanation:
let d be the distance
Number of non rainy days in week is (5-1) =4
Number of weeks = 4
in a week a student travels 4d
in 4 weeks a student travels 4×4×d = 4(4)(d)= 16d
