ANSWER:
1.9
EXPLANATION:
Volume of a pyramid = V= lwh/3
V= Volume
L= Length
W= Width
to get length we divide 5 by 4 which is 1.25
therefore V= 1.25×1.25×3.6/3
V= 1.89
1.89 to the nearest tenth is 1.9

Step-by-step explanation:
Near (-4.4,0)
.....
.....
Answer:
-4.4 , 0 = x , y
Step-by-step explanation:
The answer is of where the coordinates are.
As you didn't say the statements in your question.
We realize x is 4.4 times the size of y as y is '0' so this means the negative value for x is 4.4 smaller than y.

The answer is 3.53
Step-by-step explanation:
The formula for a semicircle is pi x r2 divided by 2, so divide the diameter by 2, then plug that in as the radius into the formula.
What percent of 75 is 18.75
Answer:
25%
Step-by-step explanation:
Let p be the percent
Of means multiply and is means equals
p * 75 = 18.75
Divide each side by 75
75p/75 = 18.75 /75
p =.25
Change to percent form
p = 25%
Answer:
[tex]25\%[/tex]
Step-by-step explanation:
Let the percent as x
[tex]x \times 75 = 18.75 \\ 75x = 18.75 \\ \frac{75x}{75} = \frac{18.75}{75} \\ x = 0.25 \\ \\ \\ 0.25 = \frac{25}{100} = 25\%[/tex]

You basically multiply the 2 functions together which gives you (2x + 3)(x + 1) = 2x² + 5x + 3
Answer:
The answer is C.
Step-by-step explanation:
Given that f(x) = 2x + 3 and g(x) = x + 1. So you have to multiply both functions together :
[tex]f(x) = 2x + 3 \\ g(x) = x + 1[/tex]
[tex]f(x) \times g(x)[/tex]
[tex] = (2x + 3)(x + 1)[/tex]
[tex] = 2x(x) + 2x(1) + 3(x) + 3(1)[/tex]
[tex] = 2 {x}^{2} + 2x + 3x + 3[/tex]
[tex] = 2 {x}^{2} + 5x + 3[/tex]

Answer:
t = [tex]\frac{D-M}{Mr}[/tex]
Step-by-step explanation:
Given
D = M + Mrt ( subtract M from both sides )
D - M = Mrt ( divide both sides by Mr )
[tex]\frac{D-M}{Mr}[/tex] = t
Answer:
t = D/Mr - 1/r or (D - M)/Mr
Step-by-step explanation:
D = M + Mrt
isolate t
D - M = Mrt
(D - M)/M = rt
D/M - 1 = rt
D/Mr - 1/r = t

Joylin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. She knows that the total cost to download 3 videos was $12. Her work to find the equation is shown below. Joylin’s Work Step 1 k = StartFraction 3 over 12 EndFraction = 0.25 Step 2 y = 0.25 x Where did Joylin make her first error Joylin divided 3 and 12 instead of multiplying the two numbers. Joylin computed the decimal equivalent of StartFraction 3 over 12 EndFraction incorrectly. Joylin used 0.25 as the coefficient of x instead of a product of x and y. Joylin switched the numerator and the denominator when she found k.

2. 0 apples left. Pauline took most apples
3. Nelly
4. Henry
Bonus. Carla - Leonard - Henry - Jenny
Step-by-step explanation:
1. From the picture, 41/45 > 80%
2. From the picture, 36/45 = 80%, therefore 80% + 20% = 100% of the apples were taken.
3. From the picture, 20/45 is between 40% and 50%, then 20/45 < 55%
4. From the picture, 15/45 is between 30% and 40%, then 15/45 < 40%
Bonus. Carla: 9/45 or 20%
Leonard: 9/45*2 = 18/45 or 40%
Jenny: 36/45 or 80%
Henry: 36/45*1/2 = 18/45 or 40%
A plane takes off from New York with 72 of the 90 seats occupied. what percentage of the seats are not occupied?
Answer:
1/5 = 20% not occupied.
Step-by-step explanation:
There are 72 occupied seats out of 90 total seats. We can say that there are 18 empty seats (90 - 72 = 18).
So there are 18 out of 90 seats occupied. We can rewrite that as 18/90. 18/90 simplifies to 9/45 = 3/15 = 1/5 = 20%.
As such, 20% of the seats are not occupied.

The foci and the vertices of the hyperbola are labeled.
Which equation represents the hyperbola shown in the graph?
Answer:
The top one, that is the hyperbole.
The equation of hyperbola is [tex]\frac{(y-5)^{2} }{9 } -\frac{(x-3)^{2} }{16 } = 1[/tex]
What is a hyperbola?A plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant : a curve formed by the intersection of a double right circular cone with a plane that cuts both halves of the cone.
What is standard hyperbola equations?• If the foci lie on the x-axis, the standard form of a hyperbola can be given as,
[tex]\frac{(x-h)^{2} }{a^{2} } - \frac{(y-k)^{2} }{b^{2} } = 1[/tex]
• If the foci lie on the y-axis, the standard form of the hyperbola is given as,
[tex]\frac{(y-k)^{2} }{a^{2} } -\frac{(x-h)^{2} }{b^{2} } = 1[/tex]
• Coordinates of the center: (h, k).
• Coordinates of vertices: (h+a, k) and (h - a,k)
• Co-vertices correspond to b, the ” minor semi-axis length”, and coordinates of co-vertices: (h,k+b) and (h,k-b).
• Foci have coordinates (h+c,k) and (h-c,k). The value of c is given as, c2 = a2 + b2.
• Slopes of asymptotes: y = ±(b/a)x.
According to the question
Foci = (3,7) (3,-3)
Vertices = (3,5) (3,-1)
As per coordinates and graph the hyperbola is vertical so x will be constant y varies
Distance between foci = 2c (where c is center)
10 = 2c
C = 5
Therefore Centre (h,k) = (3,5)
Distance between vertices = 2a
2a= 6
a = 3
The value of c is
[tex]c^{2} = a^{2} + b^{2}[/tex]
25 = 9 + [tex]b^{2}[/tex]
[tex]b^{2}[/tex] = 16
Now as per our equation
h=3 , k=5 , [tex]a^{2}[/tex] = 9, [tex]b^{2}[/tex] = 16
[tex]\frac{(y-k)^{2} }{a^{2} } -\frac{(x-h)^{2} }{b^{2} } = 1[/tex]
[tex]\frac{(y-5)^{2} }{9 } -\frac{(x-3)^{2} }{16 } = 1[/tex]
Hence, equation of hyperbola = [tex]\frac{(y-5)^{2} }{9 } -\frac{(x-3)^{2} }{16 } = 1[/tex]

The new balance of Alice Rayburn is $1241.11.
What is a periodic rate?A periodic interest rate is one that can be applied to a loan or earned on an investment over a given time frame.
Given that Alice Rayburn's previous balance is $1485.23.
And the periodic rate is 1.95%.
She made the minimum payment of 2% of previous balance.
That means 2% of $1485.23 = 1485.23 × 2 / 100 = 29.7046
She returned a pair of tennis shoes and a jacket for a credit of $68.63 and $117.47.
Total amount that she returned = $68.63 + $117.47 = $186.1
Now after return her amount is $1671.33.
She has deduction of $49.50 + $65.32 + $45.10 = $159.92
Now her amount after purchase = $1671.33 - $159.92 = $1511.41
She had total charges = $15.89 + $20.22 + $52.54 + $156.32
= $244.97
Now her amount = $1511.41 - $244.97 = $1266.44
Now after the periodic rate,
2% of $1266.44= $25.3288
So final amount after the calculation is $1241.11.
Therefore, the new balance is $1241.11.

If c = d and b ≠ 0, then c∕b = d∕b represents the property of equality. Question 4 options: A) division B) multiplication C) addition D) subtraction
Answer:
Property of equality division
Step-by-step explanation:
Given
c = d
b ≠ 0 then c∕b = d∕b
Required
State the property used
From list of options a through d, only option A best fits the description.
This is so because property of equality division is such that
given two variables c and d where c = d
[tex]\frac{c}{b} = \frac{d}{b}[/tex]
Provided that b ≠ 0
Take for instance;
b = 2; c = 8 and d = 8;
This implies that
[tex]c = d[/tex]
[tex]8 = 8[/tex]
Divide both sides by 2 (assumed value of b)
[tex]\frac{8}{2} = \frac{8}{2}[/tex]
[tex]4 = 4[/tex]
