Answer:

the area of the garden is 34

Step-by-step explanation:

in order to solve this problem you would have to essentially just use the formula which is A= length times width

in this case you would have to multiply 4 by 8 1/2 in order to get 8 1/2 into a fraction to make it easier to multiply you would multiply 8 by 2 and add 1 so your fraction would be 16/2. So the denominator 2 cancels with 4 giving you 2 times 17 and that would be 34

sorry if that was confusing but i really hope this helps!! have a good day! and just ask if you don't understand still i'm sure i can clarify :D

Answer: w = -3/2u + 2

Step-by-step explanation: The independent variable, normally x, is not impacted by other variables. The problem is asking you to put the equation in w= form. W is the dependent variable while u is the independent variable (we’re used to seeing y= form, where x is independent and y is dependent. This is the same thing with different letters).

-12u + 13 = 8w - 3

-12u + 16 = 8w (add 3 to both sides)

(-12u + 16)/8 = w (divide both sides by 8)

-12/8u + 16/8 = w

-3/2u + 2 = w (simplify)

Answer: w = -3/2u + 2

Answer:

The tree is about 8 feet.

Step-by-step explanation:

7 2/3 = 7.6 as a fraction.

30 1/5 = 30.5 as a fraction.

Know, we must divide 30.5 by 7.6.

30.5 ÷ 7.6 = 4 when rounded to the nearest whole number.

Since we know that the stake is 2 feet, we must multiply this by 4, since the other shadow is 4 times the amount of the stake.

2 x 4 = 8

This means the tree is about 8 feet.

Answer:

-5/2

Step-by-step explanation:

Answer:

Option (b).

Step-by-step explanation:

It is given that Adrian built a structure out of 10 congruent cubes.  

Volume of each cube = 8 cubic centimetres.

We need to find the total volume of the structure.

Total volume = No. of cubes × Volume of each cube

\(V=10\times 8\)

\(V=80\)

Therefore, the total volume of the structure is 80 cubic centimetres.

Hence, option (b) is correct.

Step-by-step explanation:

The bag starts with 8 red marbles, 4 green marbles, and 2 yellow marbles. Since he draws a red marble from the bag and does not replace it, there will be one less marble.

So now there are 7 red marbles, 4 green marbles, and 2 yellow marbles. Add the number of marbles together and then find the probability of drawing a yellow marble.

7+4+2 = 13

2/13

So the probability of Bill drawing a yellow marble would be 2/13.

Answer:

X= -1

Step-by-step explanation:

\((\frac{1}{3} )(6x)+(\frac{1}{3} )(-15)=(\frac{1}{2} )(10x)+(\frac{1}{2} )(-4)\)

(Distribute)

2x+−5=5x+−2

2x−5=5x−2

Step 2: Subtract 5x from both sides.

2x−5−5x=5x−2−5x

−3x−5=−2

Step 3: Add 5 to both sides.

−3x−5+5=−2+5

−3x=3

Step 4: Divide both sides by -3.

Which = -1

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer:

C = 15m

Step-by-step explanation:

Since the almonds are $15 per kg, the cost can be represented by 15m, where m is the number of kg.

To create the equation, set this equal to C, the cost in dollars:

C = 15m

So, the equation is C = 15m

Here is an equation to represent the relationship between the cost, C, in dollars, and the mass, m, in kg of almonds sold at a rate of $15 per kg at a local store: C = 15m

The mass of the almonds closely relates to how much they cost. This implies that the price of almonds will rise along with the mass of the nuts. Since the proportionality constant is $15, the price will be $15 for every kilogram of almonds.

Let's use an illustration to try to comprehend this. A 2 kg purchase of almonds will cost $30. Since 2 x 15 = 30, this is the case.

Answer:

x=12

Step-by-step explanation:

Simplifying 5x + -9 = 3x + 15 Reorder the terms: -9 + 5x = 3x + 15 Reorder the terms: -9 + 5x = 15 + 3x Solving -9 + 5x = 15 + 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3x' to each side of the equation. -9 + 5x + -3x = 15 + 3x + -3x Combine like terms: 5x + -3x = 2x -9 + 2x = 15 + 3x + -3x Combine like terms: 3x + -3x = 0 -9 + 2x = 15 + 0 -9 + 2x = 15 Add '9' to each side of the equation. -9 + 9 + 2x = 15 + 9 Combine like terms: -9 + 9 = 0 0 + 2x = 15 + 9 2x = 15 + 9 Combine like terms: 15 + 9 = 24 2x = 24 Divide each side by '2'. x = 12 Simplifying x = 12

Answer:

1872 ft.²

Step-by-step explanation:

First lets figure out all of the easy shapes:

The bottom one: 8 * 7 = 56

The one on the left: 5 * 8 = 40

The one of top: 8 * 3 = 24

The slanted rectangle: 5 * 8 = 40

The small rectangle below that : 2 * 8 = 16

Now we just have the polygon facing toward us. It can be broken up into 2 parts:

The lower half: 2 * 7 = 14

Imagine a line going from the top of the line marked "2" straight across to the other side. That is the bottom half. Now we are left with a trapezoid. The formula for the area of a trapezoid is as follows:

A = ((a + b) / 2) * h

What this means is that we had the top and bottom of the figure, divide that by 2, and multiply it by the height. That can be shown here:

(3 + 7) / 2 = 5 * 3 = 15

15 is the area of the trapezoid. Now we can combine that with 14 to get the total area of the polygon:

14 + 15 = 29

Then do the same again for the other identical figure

14 + 15 = 29

Now we have all the areas of our shapes. Let's add them up:

56 + 40 + 24 + 40 + 16 + 29 + 29 = 234

234 is the total surface area of the box. Since there are 8 boxes, multiply this by 8 to get your final answer:

234 * 8 = 1872 ft.²

Don't forget to include units!

The solution is : 1872 ft.² of the new material is needed to build all 8 containers.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

Answer:

\(y=\frac{-5}{4}x+5\)

Step-by-step explanation:

Slope intercept form: \(y=mx+b\) where \(m\) is the slope and \(b\) is the y-intercept (the value of y when the line crosses the y-axis)

1) Find the slope of the line (\(m\))

To do this, we can plug the two given points (0,5) and (4,0) into the slope equation:

\(\frac{y_2-y_1}{x_2-x_1} \\= \frac{0-5}{4-0}\\= \frac{-5}{4}\)

Therefore, the slope of the line is \(\frac{-5}{4}\).

2) Find the y-intercept of the line (\(b\))

Recall that the y-intercept is the value of y when the line crosses the y-axis. We don't actually need to perform any calculations because on the graph, we can see that the line crosses the y-axis when y=5.

Therefore, the y-intercept of the line is 5.

Plugging both \(m\) and \(b\) into \(y=mx+b\), we have a final equation of:

\(y=\frac{-5}{4}x+5\)
