Step-by-step explanation:
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

Answer: A - 8
Step-by-step explanation:
7 equals 6 plus AB divided by 2
7 times 2 is 14
14 - 6 = 8
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
Which of the following values is the solution to the equation
m + (-38) = 15 ?
1.)53
2.)-53
3.)-23
4.)23
Answer:
Step-by-step explanation:
m -38 = 15
m = 53
the answer is 1
Answer: the answer to your question is 53...
Explanation: I know I'm super late but let me explain why it's 53...
If you go on a calculator and type 53+ (-38) the answer would be 15 which can only mean that M=53. That is why it is 53 go try it out...

so there's this cone stuff and i needa know
Hey there! I'm happy to help!
To find the volume of a cone, you take the area of the base, multiply it by the height and divide it by three.
We see that the radius of our base is three. To find the area of the base, we will square the radius and multiply it by 3.14 (formula for area of circle).
3²=9
9×3.14= 28.26
We multiply it by the height.
28.26(2)=56.52
We divide it by three.
56.52/3=18.84
Therefore, the area is 18.84 units cubed.
Now you can find the volume of cones! I hope that this helps! Have a wonderful day!
Adding which terms to 3x2y would result in a monomial? Check all that apply
Answer:
By adding 12x²y and 4x²y result will be a monomial.
Step-by-step explanation:

Consider a triangle ABC like the one below. Suppose that C equals 97° a equals 40 and b equals 17 sold the triangle carry your intermediate computations and to at least four decimal places around your house or to the nearest 10th if there are more than one solution use the button labeled or
Answer:
c = 45.33, C =97°, a = 40, A = 61.15° , B = 21.85°, b = 17
Step-by-step explanation:
Given that:
C = 97°, a = 40 and b = 17.
We have angle C, we need to find the side the side c opposite to the angle C. we have side a, we need to find the angle A opposite to side a. we have side b, we need to find the angle B opposite to side b.
Using cosine rule:
c² = a² + b² - 2ab × cos(C)
c² = 40² + 17² - 2(40)(17)cos(97)
c² = 2054.74
c = 45.33
Also using sine rule:
[tex]\frac{a}{sin(A)} =\frac{c}{sin(C)} \\\frac{40}{sin(A)}=\frac{45.33}{sin(97)} \\sin(A)=\frac{sin(97))40}{45.33}=0.876\\A=sin^{-1}(0.876)=61.15^0[/tex]
Also:
[tex]\frac{b}{sin(B)} =\frac{c}{sin(C)} \\\frac{17}{sin(B)}=\frac{45.33}{sin(97)} \\sin(B)=\frac{sin(97))17}{45.33}=0.3722\\B=sin^{-1}(0.3722)=21.85^0[/tex]
c = 45.33, C =97°, a = 40, A = 61.15° , B = 21.85°, b = 17

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
Simplify (5^3)^6 leaving your answer in index form
[tex]( {5}^{3} ) ^{6} = {5}^{3 \times 6} = {5}^{18} [/tex]
Answer:
5^18.
Step-by-step explanation:
By the law of indices:
(a^b)^c = a^(bc)
So (5^3)^6
= 5^(3*6)
= 5^18.
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

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.
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]

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

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.
