HELP PLEASE !! which right prism would have the same volume as a square prism with a base area of 36 m 2 and a height of 3 m ?
Answers
Answer:
3 x 36 = 108 (square prism's volume)
3 x 9 = 27, 27 divided by 2 ( x 1/2) = 13.5, 13.5 x 4 = 54
2 x 18 x 3 = 108
6 x 3 = 18, 18 x 2 = 32
Your answer is b, because it has the volume of 108 which matches the square prism's volume.
Mrs. Jackson has only $127.50 to spend at a clothing store. He
wants to buy a shirt that costs $87, including tax, and some
bracelets that cost $4.50 each, including tax.
Write an equation to determine, x, the amount of bracelets Mrs.
Jackson could buy.
Equation: ________________________________________________
Solve the equation to determine the number of bracelets Mrs.
Jackson could buy.
Answers
Answer:
$4.50x = $127.50 - $87
x = $40.50 / $4.50
x = 9
Step-by-step explanation:
The amount she can spend on bracelets is the total amount she wants to spend less the cost of the shirt
$4.50x = $127.50 - $87
4.50x = 40.50
divide bot side by 4.5
x = 9

The spinner is spun 48 times. What is a reasonable prediction for the number of times the spinner will land on an even number?
Answers
Answer:
18 times
Step-by-step explanation:
Number of even numbers on spinner = 3
Total number of sections on spinner = 8
Probability of obtaining an even number on one spin = 3/8
Number of times an even number can be obtained from 48 spins = 3/8 * 48 = 18 times

the picture frame shown are both squares the area of a larger frame is four times the area of the smaller frame find the side length of the larger frame. a=64 in sq
Answers
Answer:
The side length of the larger square is 32
Step-by-step explanation:
Its 32 because the side lengths for the small square are 8 because 8 by 8 is 64. Multiply 8 by 4 which is 32.
Answer:
The side length of the larger frame is 128 inches.
Step-by-step explanation:
64 × 4 = 256
256 ÷ 2 = 128
assume x and y are two odd numbers and x/y is an integer. which of the following statements are true?
1. x+y is odd
2. xy is odd
3. x/y is odd
4. x-y is odd
pls help me and DONT answer in link
Answers
Answer:
2. xy is odd
Step-by-step explanation:
We can represent the two odd numbers as 2a + 1(x) and 2b + 1(y).
1. x + y is odd
We can add x + y:
2a + 1 + 2b + 1
2a + 2b + 2
From this, we can factor out 2:
2(a + b + 2)
Since 2 is a factor, the number x + y cannot be odd.
2. xy is odd:
We can multiply x and y:
(2a + 1)(2b + 1)
4ab + 2a + 2b + 1
From the first three terms, we can factor out 2:
2(2ab + a + b) + 1
We can say that 2(2ab + a + b) is an even number because it has a factor of 2. We are adding one to it, and one added to any even number is odd, so xy is odd.
We do not need to calculate further because we have already found an answer.
Una escalera de 30 pies de longitud está apoyada contra una pared de modo que su extremo superior se desliza hacia abajo con una velocidad de 1/2 pies/seg ¿cuál es la tasa de variación de la medida del ángulo formado por la escalera y el piso cuando el extremo superior está a 18 pies del piso?
Answers
Answer:
dα /dt = - 0.028 rad /sec or dα /dt = - 1.59 °
El signo menos significa que el angulo va decresiendo
Step-by-step explanation:
La escalera, la pared vertical y el pié de la escalera y la pared forman un triangulo rectangulo. En ese triangulo
cos α ( α angulo que forma la escalera con el piso )
cos α = x / L
Tomando derivadas con respecto al tiempo (L es constante ) se tiene:
- sen α * dα / dt = dx/ dt / L
Cuando el extremo superior de la escalera está a 18 pies del piso, entonces sen α = 18 / 30 = 0.6
dx/dt = 1/2 pie/sec
dα/dt = - (1/2)/ L* 0.6
dα /dt = - 0.5 / 18
dα /dt = - 0.028 rad /sec or dα /dt = - 1.59 °
El signo menos significa que el angulo va decresiendo

Mr kacanich was baking a chocolate cake. The recipe called for 3/4 cup of unsweetened cocoa powder, but after he started mixing ingredients, he relized he didn't have enough. If mr kacanich borrowed 1/4 cup from the neighbor, how much of his own cocoa powder did he have?
Answers
Answer:
2/4 cup
Step-by-step explanation:
Unsweetened cocoa powder needed = 3/4 cup
Unsweetened cocoa powder borrowed = 1/4 cup
how much of his own cocoa powder did he have?
Let
x = Unsweetened cocoa powder Mr kacanich has
Unsweetened cocoa powder needed = Unsweetened cocoa powder Mr kacanich has + Unsweetened cocoa powder borrowed
3/4 = x + 1/4
Subtract 1/4 from both sides
3/4 - 1/4 = x + 1/4 - 1/4
3/4 - 1/4 = x
x = (3-1)/4
x = 2/4 cup
Please use system of linear equations by elimination OR substitution. I need the work as well please.
Answers
1) P= 64 cm, width = x, length = 14 + x
64 = x + x + 14 + x + 14 + x
64 = 4x + 28
4x = 64 - 28
4x = 36
x = 36/ 4
x = 9
AREA = 9 x (9+14)
Area = 9 x 23
Area = 207 cm
2) smaller no. = y, bigger no. = x
x - y = 3
2x+1/2y=36
Next, multiply 2 to first equation and find y:
2x-2y=6
5/2y=30
y = 12
Substitue y to x-y=3 to find x,
x = 15
3) x = pencil, y = pen
5x + 4y = $6.15
8x + 3y = 9.85$
8x + 7y = ?
5x + 4y = 6.15$ multiply both sides by -3
8x + 3y = 9.85$ multiply both sides by 4
-15x + 32x = (-3)*6.15 + 4*9.85
7x = 19.87 multiply both sides by 8/7
8x = (8/7) x 19.87
Add both equations:
32y - 15y = 8x6.15 - 5*9.58
17y = 1.3
y = 91/17) x 1.3
7y = (7/17)x 1.3
8x + 7y = (8/7) x 19.87 + (7/17) x 1.3
8x + 7y = $23.244
4) 2l + 2w = 0
2 x 2l + 2 x 1/2w = 40 + 16
l+w = 20
4l+w = 56
I’ve got l = 12 and w = 8
5) answer: 28.56 feet (approx)
step-by-step explanation:
since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.
we have to find out the measurement of segment ab.
therefore, tan 55° = \frac{ab}{bc}
but bc = 20 feet.
⇒ tan 55 ° = \frac{ab}{20}
⇒ ab = 20 × tan 55 °
⇒ ab = 20 × 1.42814800674
⇒ ab = 28.5629601348 ≈ 28.56 feet
