Complete Question

In ΔVWX, w = 780 cm, ∠X =21° and ∠W=146°. Find the length of x, to the nearest 10th of a centimeter.

Answer:

499.9cm

Step-by-step explanation:

We solve for length x using the Sine rule

w/ sin W = x /sin X

Cross Multiply

x × sin W = w × sin X

x = w × sin X/ sin W

x = 780 × sin 21°/ sin 146°

x = 499.88 cm

Approximately to nearest tenth = 499.9cm

she spent 35 minutes on her homework

Step-by-step explanation:

Answer:

35 minutes.

Step-by-step explanation:

Because at 9:20, it's been 10 minutes. Then at 9:30, it's been 20 minutes, then at 9:45 it has been 15 minutes which all that added up is 35.

Answer:

3x^2 + 3  -->  6, 15, 30, 51

2x^2 - 1    -->  1, 7, 17, 31

x^2 + 2     -->  3, 6, 11, 18

Step-by-step explanation:

Let's start with the first equation; 3x^2 + 3

Substitute 1 (the first digit in a sequence) for x.

3(1^2) + 3

3(1) + 3

3 + 3 = 6

3(2^2) + 3 Then the second digit.

3(4) + 3

12 + 3 = 15

Since the two numbers we have so far are 6 and 15, there is only one sequence this could match. 6, 15, 30, 51.

2(1^2) - 1

2(1) - 1

2 - 1 = 1

This equation represents 1, 7, 17, 31.

These same steps apply to the other equation as well.

1^2 + 2, then 2^2 + 2, then 2^2 + 2, and so on. (But we don't need to do extra work to figure that out.)

Answer: x=+2

Step-by-step explanation:2x-6=12x-26

We move all terms to the left:

2x-6-(12x-26)=0

We get rid of parentheses

2x-12x+26-6=0

We add all the numbers together, and all the variables

-10x+20=0

We move all terms containing x to the left, all other terms to the right

-10x=-20

x=-20/-10

x=+2

Step-by-step explanation:

The cucumber were sold at $224.

A single unit's value may be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary technique. We typically utilise this technique for math computations.

This approach allows us to calculate both the value of many units from the value of one unit and the value of many units from the value of one unit.

Given:

area of garden = 56 square feet.

1 cucumber = 72 square inches = 0.5 square feet

Number of cucumbers

= 56 / 0.5

= 112 cucumbers

Price for each cucumber = $2

So, price for 112 cucumber = 112 x 2

                                            = $224

Hence, the cucumber were sold at $224.

Answer:

the bisector is PR

MN= 7 2/3

Step-by-step explanation:

bisector cuts something in half and the lines on the line prove its in 2 equal parts so the line intersecting it is PR

since MN is bisected by PR and on side of MN in 3 5/6 just multiply 3 5/6 by 2 to get the answer

Answer:

Charles need [tex]3\frac{1}{5}[/tex] more ounces of seeds.

Step-by-step explanation:

Given that:

Quantity of seeds Charles has = [tex]2\frac{2}{3}[/tex] = [tex]\frac{8}{3}[/tex] ounces

Quantity of seeds Charles need = [tex]4\frac{4}{5} = \frac{24}{5}[/tex] ounces

Let,

x be the number of remaining seeds Charles need.

x = Seeds needed - Seeds Charles already have

x = [tex]\frac{24}{5}-\frac{8}{3}[/tex]

x = [tex]\frac{72-24}{15}[/tex]

x = [tex]\frac{48}{15}[/tex]

x = [tex]\frac{16}{5}[/tex]

x = [tex]3\frac{1}{5}[/tex] ounces

Hence,

Charles need [tex]3\frac{1}{5}[/tex] more ounces of seeds.

Step-by-step explanation:

Exponential functions are written y = ab^x where a is the starting point and b is the common ratio. We know the initial worth is 52500 and each year the worth decreases 9% of the original year, making it work 91% of the previous value.

Answer:

The entire area of the sailboat is 60cm²

Step-by-step explanation:

You can find the area of this shape by breaking it down into simpler shapes and adding up their individual areas.

In this case, the areas we'll use are the rectangle at the bottom, and the pair of triangles at the top.

Because the two triangles can be put together to form a single triangle, we don't need to measure them independently.  We can simply take the total length of their bases, multiply it by their height, and divide by two.  This follows the rule that the area of a triangle is equal to the area of the square that contains it divided by two.

(2cm + 3cm) × 6cm

= 5cm × 6cm

= 30cm²

The rectangle's area is of course equal to its width times its height, so we can say:

2.5cm × 12cm

= 30cm²

The total area of the shapes then is 30cm² + 30 cm², giving us a total area of 60cm²
