what is the value of this expression?

Answer:

Where is the graph?

Step-by-step explanation:

Formula used,

Area of rhombus = Base × height

Substituting the values,

\( \longrightarrow\)Area = 18 × 15.5

\( \longrightarrow\) Area = 279 cm²

Therefore, 279 cm² is the area of the rhombus .

Answer:

D) 279 cm²

Step-by-step explanation:

Area of a rhombus formula:
\(A=bh\)

This formula is also used for squares and rectangles.

So, we can substitute in our values such as:

A=(18)(15.5)

simplify

A=279

Now, add our label and units:

A=279 cm²

Answer:

3.2%

Step-by-step explanation:

The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).

Given that,

The dot plot shows predictions for the winning time in the​ 200-meter sprint.
The winner finished the race in 22.5 seconds.

We have to determine,

What is the greatest percent error among the​ predictions.

According to the question,
The true finishing time is 22.5 seconds.
The prediction furthest from this is 22.9 seconds.
This is a difference of 22.9 - 22.5 = 0.4 seconds. 

Divide this over the true time value to get prediction,
0.4/22.5 = 0.0177 = 1.77 (Approximately)

Move the decimal point to the right 2 spots to get to 1.773% (Approximately 1.8%).

Hence, The required greatest percent error among the predictions is 1.773% (Approximately 1.8%).

Hope my answer helps you.

Answer:11

Step-by-step explanation:I think

answer:  the maximum number of weeks Sally can remove $50 from the account and still have at least $75 is 11 weeks.

show my work :

Let W be the number of weeks Sally has been withdrawing money.  The total in the account would be represented by 650-50W at any given time.

To remain over or equal to $75 the equation to solve is

650 - 50W >= 75

we need to get the variable on one side and the constants on the other so subtract 650 from each side...

-50W >= 75-650

-50W >= -575

Now we need to divide out the coefficient of the variable so divide both sides by -50.   Note that multiplying or dividing an inequality by a negative reverses the inequality so...

W <= (-575)/(-50)

W <= 11.5

So in whole numbers the maximum number of weeks Sally can remove $50 from the account and still have at least $75 is 11 weeks.

Answer:

Step-by-step explanation:

Surface area of a cube = 6a²

When each dimension is doubled,  Side =2a

Surface area = 6*(2a)² = 6 * 4*a² = 4*(6a²)

So, when each dimension is doubled, surface area is 4 times of the original surface.

a = 3a

Surface area = 6*(3a)² = 6 * 9 *a² = 9 *6a²

                     = 9 times the original area

a = 4a

Surface area = 6*(4a)² = 6* 16 * a²

                     = 16 * (6a²)

                     = 16 times of original area

Answer:

◘ 12 pears

◘ 3 pineapples

◘ 10 kiwis

Step-by-step explanation:

Let \(x\) be the number of pears bought.

Therefore:

• number of pears = \(x\)

• number of pineapples = \(x - 9\)

• number of kiwis = \(x - 2\)

We know that the total cost was $13.50.

This means if she bought \(x\) pears at $0.50 each, \((x - 9)\) pineapples at $1.50 each, and \((x -2)\) kiwis at $0.30 each, the total would be $13.50.

∴  \([x \times 0.50] + [(x-9) \times 1.5] + [(x-2) \times 0.3] = 13.50\)

Expanding and multiplying:

⇒ \(0.5 x + 1.5x - 13.5 + 0.3x - 0.6 = 13.5\)

Collect like terms:

⇒ \(2.3x -14.1 = 13.5\)

Solve for \(x\):

⇒ \(2.3x = 13.5 + 14.1\)

⇒ \(2.3 x = 27.6\)

⇒ \(x = 27.6 \div 2.3\)

⇒ \(x = \bf 12\)

Therefore, she bought:

• 12 pears

•  \(x - 9\) = 12 - 9 = 3 pineapples

• \(x - 2\) = 12 - 2 = 10 kiwis

Marita bought 12 pears, 3 pineapples and 10 kiwis.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

Let x the number of pears bought,

y the number of pineapples bought,

z the number of kiwis bought,

Given that, Marita bought 9 more pears than pineapples and 2 fewer kiwis than pears,

y + 9 = x

y = x -9 and

z + 2 = x

z = x - 2

We know that the total cost was $13.50.

This means if she bought  pears at $0.50 each,  pineapples at $1.50 each, and  kiwis at $0.30 each, the total would be $13.50.

∴  0.50x + 1.50y+ 0.30z = 13.50

Substitute the values of y and z in equation,

⇒ 0.50x + 1.50(x -9)+ 0.30(x - 2) = 13.50

Expanding and multiplying terms in equation,

⇒  0.50x + 1.50x -13.50+ 0.30x - 0.60 = 13.50

Rearrange the like terms and apply the arithmetic operation

⇒ 2.3x - 14.1 = 13.50

⇒ 2.3x = 13.50 + 14.1

⇒ 2.3x = 27.6

⇒ x = 27.6/2.3

⇒ x = 12

Therefore, the number of pears bought = 12

So, the number of pineapples bought = 12 - 9 = 3

And the number of kiwis bought = = 12 - 2 = 10

Hence, Marita bought 12 pears, 3 pineapples and 10 kiwis.

Answer:

C. The mean increases by 1.4°.

Step-by-step explanation:

if you count the number of numbers in the set {58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57} it is 12 numbers.

The formula for mean is,  \(mean=\frac{sum- of- the- terms}{number-of-terms}\)

so if you add all the numbers here →,  {58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57}  you get a sum of 965.

Now 965 ➗12= 80.4166666667

If 98 is added we add 98 to 965 and get 1063.

That also means an additional number is being added so 12+1 = 13.

Now, 1063➗13= 81.7692307692

Ok now we approximate, 80.4166666667 is about 80.4 and 81.7692307692 is about 81.8.

Now we subtract 81.8-80.4 and get 1.4.

It was an increase of 1.4 in the mean so the answer is C.

The area of the parallelogram given in the image is 72 square units.

The area of a parallelogram is taken as base × height because it can be divided into two different parts and then reshuffled to make a rectangle, whose area is also base × height.

We know that the area of a parallelogram = base × height  ......(i)

Also, we are given quantities for base = 6 units

and height = 12 units

So, putting the values in equation (i), we get

⇒ area = base × height

⇒ area = 6 × 12

⇒ area = 72 square units

So, the area of the parallelogram given is 72 square units.

Part A: To record an equating defining this position, we can start by canny the total distance camouflaged in d supplementary days. Since the kin drives 350 5 per epoch each surplus era, the total distance marked in d supplementary days is 350d. Adding the beginning 200 5 compelled on the first epoch, the equating enhances:200 + 350d = 1,600Part B: To resolve the equating and find the total number of days the offspring will travel, we need to detach the changeable d. We can start by subtracting 200 from two together hands of the equating:350d = 1,600 - 200350d = 1,400Next, we separate two together parts of the equating by 350 to resolve for d:d = 1,400 / 350d = 4Therefore, the kin will travel for an supplementary 4 days to reach a total distance of 1,600 5.

Answer:

For #6, it is 81 degrees, and for #8, it is 100 degrees.

Step-by-step explanation:

For #6, it is on the opposite side, so 81 degrees

For #8, it is also on the opposite side, so 100 degrees

Whenever there are parallel lines going horizontally, the angles measure the same on opposite sides, and to find the measure of an angle next to another angle, subtract it from 180.
