what's the answer dhdhdizdjskxi

**Answer:**

138 ft for the area in the proposed design of the green section.

To find the area of the whole shape, you gotta divide it into polygons. So, you find the area of the big rectangle at the bottom first: 18 x 7 = 126. That's the area of the big rectangle.

Then, you find the area of the little square on top. 4 x 4 - 16, that's the area. Then, you gotta add those two together: 126 + 16. The total area is **142 square feet.**

IF you add 6 tens of thousands, 5 thousands and 3 hundreds together what is the value of the largest digit of the answer?

**Answer:**

**Step-by-step explanation:**

6 tens of thousands = 60,000

5 thousands= 5,000

3 hundreds= 300

60,000

+ 5,000

The cost of 15 kg of apples is $262.50. Find the cost of 25 kg of apples

**Answer:**

525.00

**Step-by-step explanation: **

The **cost **of 25 kg of apples is **$437.5.**

"A **cost** is an expenditure required to produce or sell a product or get an asset ready for normal use. In other words, it’s the amount paid to manufacture a product, purchase inventory, sell merchandise, or get equipment ready to use in a business process.

There are many different **costs**, including fixed and variable, but they are all accounted for in the same way. **Costs** are recorded as expenses on the income statement during and accounting period and cleared out in a closing entry at the end of the period."

The **cost **of 15 kg is **$262.50.**

So, the cost of 1 apple is 262.50/15

**= 17.5 **

**Cost** of 25 kg = [tex]17.5 * 25 = 437.5[/tex]

Hence, the **cost** of 25 kg of apples =** 437.5 **

s2 - s + 2

Trying to factor by splitting the middle term

2.1 Factoring 3s2 - 2s + 1

The first term is, 3s2 its coefficient is 3 .

The middle term is, -2s its coefficient is -2 .

The last term, "the constant", is +1

Step-1 : Multiply the coefficient of the first term by the constant 3 • 1 = 3

Step-2 : Find two factors of 3 whose sum equals the coefficient of the middle term, which is -2 .

-3 + -1 = -4

-1 + -3 = -4

1 + 3 = 4

3 + 1 = 4

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Emily wants to know the volume of a beach ball. She deduces that the beach ball has diameter of 12 inches, and then uses the following formula to find the volume: (3.14) (12) V = (3.14) (1728) (5425.92) V=7234.56 cubic inches Emily's answer is incorrect. What did she do wrong? She used the formula for a cylinder instead of the formula for a sphere She used the formula for a sphere instead of the formula for a cone. Multiplying (314)(1728) does not equal 5425.92. She used the beach ball's diameter when she should have used the radius

Answer:

D. She used the beach's ball's diameter when she should have used the radius

Step-by-step explanation:

To find the volume of the beach ball, using the volume of a sphere is the right formula to use, which is ⁴/3πr³.

The formula she used is correct.

Since the diameter of the ball is assumed to be 12 inches, what is needed to find the volume is the radius.

Radius (r) = ½(diameter) = ½(12) = 6 in.

This is where Emily made a mistake.

She used the diameter of the beach ball instead of its radius (r) which is needed in the equation.

She should have gotten,

V = ⁴/3(3.14)(6)² = 904.32 cubic inches

Complete the description of the transformation.

**Answer:**

**Step-by-step explanation:**

There are two transformations, one vertical, one horizontal.

The + 9 part outside the absolute value sign moves the graph **up** 9 units.

Replacing x with x - 1 moves the graph **right** 1 unit.

*Comment:* The horizontal shifts sometimes appear backwards: x - 1 looks like a shift to the left, but it's not.

Example: f(4) = |4| = 4. To get the same output (4) from g(x), you have to use a value for x that is 1 unit larger than 4. g(5) = |5 - 1| = 4.

6x - 4y = 38

x + y = 5

Answer: y= -4/5 and x= 29/5

Step-by-step explanation:

From eqn2 , x= 5-y. Thus substituting in eqn1 will give

6(5-y)-4y=38

30-6y-4y=38

30-10y=38

-10y=38-30

-10y= 8

y=8/-10---> y= -4/5

Substituting y in eqn2 we have

x+(-4/5)=5

x=5+4/5

x=29/5

In ΔXYZ, ∠Y=90° and ∠X=40°. ∠ZWY=51° and XW=600. Find the length of ZY to the nearest integer.

The image of the triangle is missing so i have attached it.

Answer:

ZY ≈ 391

Step-by-step explanation:

From the attached image, ∠WZY = 180 - (51 + 90) = 39°. Because ΔWYZ is a right angle triangle and sum of angle in a triangle = 180°

Now, similarly ∠XZY = 180 - (40 + 90) = 50°

Using sine rule, we can find WZ;

WZ/sin 40 = XW/sin 50

We are given XW = 600

Thus;

WZ = (600 × sin 40)/sin 50

WZ = 503.5

Now, ZY can be found using trigonometric ratios;

ZY/WZ = sin 51°

Thus;

ZY = 503.5 × sin 51

ZY ≈ 391

To find the vertex, you can find the axis of symmetry by taking its equation and putting it into the form of x = -b/2a or finding the lowest or highest point in the line. In this example, it is (-1, -2) as the lowest point, and there is not a highest point to find, since it is in a u-shape.
