Answer:
A rectangle.
Step-by-step explanation:
A square would have four congruent sides. Because this does not and it has the four right angles, it is a rectangle.
A firework rocket consists of a cone stacked on top of a cylinder, where the radii of the cone and the cylinder are equal. The diameter of the cylindrical base of the rocket is 8 in and the height of the cylinder is 5 in, while the height of the cone is 3 in. Calculate the surface area of the rocket. Leave your answer in terms of π. 184π sq. in. 76π sq. in. 168π sq. in. 88π sq. in.
Answer:
(B) [tex]76\pi$ sq. in.[/tex]
Step-by-step explanation:
Since the base of the cone and one circular face of the cylinder is not visible,
The surface area of the rocket=Base Area of the Cylinder+Lateral area of the Cylinder+Lateral Area of the Cone+
[tex]R$adius =4 Inches\\Height of the cylinder =5 Inches\\Therefore:\text{Lateral area of a Cylinder+Base Area of the Cylinder}=2\pi rh+\pi r^2\\=(2\times \pi \times 4 \times 5)+(\pi \times 4^2)\\=40\pi+16\pi \\=56\pi$ sq. in.[/tex]
Lateral Area of a Cone [tex]=\pi rl[/tex]
Base radius, r= 8/2 =4 InchesPerpendicular Height of the Cone = 3 InchesUsing Pythagoras theorem:
[tex]Hypotenuse =\sqrt{opposite^2+adjacent^2} \\=\sqrt{3^2+4^2} \\=\sqrt{25}\\ =5 in.[/tex]
Slant Height of the Cone, l (Hypotenuse) = 5 InchesTherefore: Lateral Area of a Cone [tex]=\pi \times 4\times 5 =20\pi$ sq. in.[/tex]
Therefore, Surface area of the rocket
[tex]=56\pi+20\pi\\=76\pi$ sq. in.[/tex]
Answer:
The answer is 76π sq. in.

Rectangle ABCD has vertices A(–6, –2), B(–3, –2), C(–3. –6), and D(–6, –6). The rectangle is translated so that the coordinates of the image are A’(–10, 1), B’(–7,1), C’(–7, –3), and D’(–10, –3). Which rule was used to translate the image? T–4, 3(x, y) T–4, 1(x, y) T4, –1(x, y) T4, –3(x, y)'
Answer:
T₋₄, ₃ (x, y)
Step-by-step explanation:
The coordinates of rectangle ABCD are;
A = (-6, -2)
B = (-3, -2)
C = (-3, -6)
D = (-6, -6)
The coordinates of the image are;
A' = (-10, 1)
B' = (-7, 1)
C' = (-7, -3)
D' = (-10, -3)
We note that for A and A', x - x' = -6 + 10 = 4 and y - y' = -2 - 1 = -3
For B and B', x - x' = -3 + 7 = 4 and y - y' = -2 - 1 = -3
For C and C', x - x' = -3 + 7 = 4 and y - y' = -6 + 3 = -3
For D and D', x - x' = -6 + 10 = 4 and y - y' = -6 + 3 = -3
Therefore, the transformation rule used to translate the image of rectangle ABCD is T₋₄, ₃ (x, y)
Answer:
T₋₄, ₃ (x, y)

what is the quotient -3/8 and -1/3
Answer:
[tex]\frac{9}{8}[/tex]
Step-by-step explanation:
In order to find the answer to this question you will have to use KCF (Keep, Change, Flip) on the equation and then multiply.
[tex]-\frac{3}{8} \div-\frac{1}{3}[/tex]
Use KCF:
[tex]-\frac{3}{8} \times-\frac{3}{1}[/tex]
Now multiply:
Negative times a negative equals a positive.
[tex]3\times3=9[/tex]
[tex]8\times1=8[/tex]
[tex]=\frac{9}{8}[/tex]
Hope this helps.
Answer: 9/8
Explanation: It's important to understand that dividing by a fraction is the same thing as multiplying by the reciprocal of the fraction.
So our problem can be rewritten as (-3/8) · (-3/1).
Remember that a negatives times a negative is a positive.
So (-3/8) · (-3/1) is 9/8.
Remember, multiply across the top and bottom.

How many flowers, spaced every 4 in., are needed to surround a circular garden with a 100-ft radius? use 3.14
Answer:
157Step-by-step explanation:
Let us first calculate the circumference of the circular of the circular garden
[tex]C= 2\pi r[/tex]
Given
r= 100
[tex]C= 2*3.142*100\\C= 628.4 ft[/tex]

La batalla de Inglés y Matemáticas Pregunta: Tenía $ 5.00 Mi mamá me dio $ 10.00 mientras que mi papá me dio $ 30.00. Mi tía y mi tío me dieron 100.00. Tuve otros $ 5.00 ¿Cuánto dinero realmente tenía?
Answer:
$150.00
Step-by-step explanation:
Tenía $ 5.00
Mi mamá me dio $ 10.00 mientras que mi papá me dio $ 30.00.
Esto significa que luego tengo:
5 + 10 + 30 = $ 45.00
Mi tía y mi tío me dieron 100.00.
Entonces tuve:
45 + 100 = $ 145.00
Tenía otros $ 5.00.
Esto significa que en conjunto tuve:
145 + 5 = $ 150.00

The height of the building in the drawing is 12 inches. If each inch represents 3 feet, how tall is the building?
Answer:36 ft
Step-by-step explanation:
1 inch = 3ft
and there’s 12 inches on the scale
so 12(3)=36
Answer:
36 feet
Step-by-step explanation:
Since each inch represents 3 feet, 3 times 12 will equal 36.
A survey of 2400 was given to people who owned a certain type of car, 960 said they would buy that type of car again. What percent of the people surveyed were completely satisfied with the car.
Divide the number satisfied by total people surveyed then multiply by 100 for the percent.
960/2400 = 0.4
0.4 x 100 = 40%
The answer is 40%

Arya spins both spinners. What is the probability that Arya gets blue on both spinners? Give your answer as a fraction.
Answer:
2/16
Step-by-step explanation:
Since the total number on a spinner is 8 and there are 2 of them we get 8 + 8=16 and the blue one has 1 and they are 2 we get 1+1=2.
probability=desired chances/total chances
=2/16
The probability that Arya gets blue on both spinners is 2/16.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
Since the total number on a spinner is 8 and there are 2 of them we get 8 + 8 = 16 and the blue one has 1 .
we get 1 + 1 = 2.
The probability that Arya gets blue on both spinners
= desired chances/total chances
=2/16

Answer:
22 length is the answer
Answer to this question ?
Answer:
(x - 10)(x - 3)
Step-by-step explanation:
You have to think of numbers that multiply up to 30 and add up to 13. So you eliminate the numbers down to 10 and 3, because you can add up to 13 and multiply to 30. Now you have to find how it adds up to negative 13 and multiply it to postive 30. 2 negatives make a positive when multiplying, and 2 negatives added together make another negative, so your roots are 10 and 3. Put that into factored form and you have (x - 10)(x - 3).
Alternatively you can either graph to find its zeros or guess-and-check.

Arrange the equations in the correct sequence to rewrite the formula for displacement, d = vt—1/2at^2 to find a. In the formula, d is
displacement, v is final velocity, a is acceleration, and t is time.
Answer:
[tex]a = \frac{2(vt-d)}{t^{2} }[/tex]
Step-by-step explanation:
Given the formula for calculating the displacement of a body as shown below;
[tex]d = vt - \frac{1}{2} at^{2}[/tex]
d = displacement
v = final velocity
a = acceleration
t = time
To make the acceleration a the subject of the formula, the followin steps must be taken;
Step 1: Subtract vt from both sides of the equation
[tex]d-vt = vt-vt-\frac{1}{2}at^{2} \\ d-vt = -\frac{1}{2}at^{2}\\2(d-vt) = -at^{2}[/tex]
Step 2: Divide both sides by t²
[tex]\frac{2(d-vt)}{t^{2} } = \frac{-at^{2} }{t^{2} } \\a = \frac{-2(d-vt)}{t^{2} }[/tex]
[tex]a = \frac{2(vt-d)}{t^{2} }[/tex]

The Math Club is ordering food to be delivered to their meeting. They have a coupon for $10 off their order, and each member contributes an additional $5 for the food. The expression 5n + 10 represents the total amount they can spend on their order. Why would it not make sense to substitute 12.125 for n in this expression? A n represents the number of members, so it must be a whole number. B 5n represents the number of members, so n must be a whole number. C n represents an amount of money, so it cannot have more than two decimal places. D 5n represents an amount of money, so n cannot have more than two decimal places.
Answer:
A. n represents the number of members, so it must be a whole number.
Step-by-step explanation:
Since 12.125 is a decimal, it would not make sense to substitute 12.125 for n in the expression. You cannot have 1/8 of a person. Since each member is contributing an additional $5, the expression will show n as the variable representing the number of members in the Math Club. Each member is giving 5, so 5n + 10, the 10 being the coupon they have for $10 off. This expression shows how much money the entire group has.
