Step-by-step explanation:

1. We need to find the value of 8.1 × 10³ − 2.4 × 10² in standard form.

We can also write its as :

8.1 × 10³ − 2.4 × 10²

81000 − 240

Standard form = 80760

2.

Amy's weight = 40 kg

Blood comprises 8% of the weight of a human.

Weight of her blood,

[tex]W=8\%\ of\ 40\\\\=\dfrac{8}{100}\times 40\\\\=3.2\ kg[/tex]

So, the weight of her blood is equal to 3.2 kg.

Answer:

[tex]A=54.95\ ft^2[/tex]

Step-by-step explanation:

The angle of shaded sector = 360-332 = 28°

The radius of sector, r = 15 ft

We need to find the area of the shaded sector. The formula for the area of the sector is given by :

[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\=\dfrac{28}{360}\times 3.14\times (15)^2\\\\A=54.95\ ft^2[/tex]

So, the area of the shaded sector is equal to [tex]54.95\ ft^2[/tex].

Answer:

Another way to prove triangles are similar is by SSS, side-side-side. If the measures of corresponding sides are known, then their proportionality can be calculated. If all three pairs are in proportion, then the triangles are similar.

Answer:

(2) Five added to the product of 2 and p is less than 11.

Step-by-step explanation:

2p + 5 is represented by five added to the product of 2 and p.

This is because 2p is the product, and 5 is added to it.

The less than inequality means that 2p + 5 is less than 11.

So, the correct statement is (2) Five added to the product of 2 and p is less than 11.

Answer: 60 holes

Step-by-step explanation:

Nate made par or better 34 out of 85 holes. You need to use this to find the rate at which he makes par or better holes:

= 34 / 85 * 100%

= 40%

40% of the time he makes par or better holes.

If there are 150 holes left, he will make par or better of:

= 40% * 150

= 60 holes

Answer: $4.99

Step-by-step explanation:

The amount that Savannah paid for the 3 pairs of socks will be gotten by subtracting $5.03 from $20 which will be:

= $20 - $5.03

= $14.97

Since each paid of socks cost thesame amount, the cost of each pair of socks will be:

= $14.97/3

= $4.99

Each pair of socks cost $4.99

Answer:

4,500

Step-by-step explanation:

150,000x.03=4500

The commission of the real estate agent is 4500 which is 3% of 150,000.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, A real estate agent earns a 3% commission on each house she sells and she sells a 150,000 house.

So, His commission is 3% of 150,000.

Therefore,

Commission = (3/100)×150000.

Commission = 4500.

So, The commission of the real estate agent is 4500.

12 is being decreased by 2x (x is a variable for a number)

Answer:

Clare starts with:

a*x^2 + b*x + c = 0

And she gets to:

(2*a*x + b)^2 = b^2 - 4*a*c

Now we want to show the final steps to solve the equation (isolating x)

First, we apply the square root to both sides:

[tex]\sqrt{(2*a*x + b)^2} = \sqrt{(b^2 - 4*a*c)}[/tex]

Because the square root has two solutions, (one negative and one positive), we will write:

[tex]2*a*x + b = \pm \sqrt{b^2 - 4*a*c}[/tex]

Now we subtract b in both sides:

[tex](2*a*x + b) - b = \pm \sqrt{b^2 -4*a*c} - b[/tex]

[tex]2*a*x = \pm \sqrt{b^2 -4*a*c} - b[/tex]

Now let's divide by 2*a in both sides:

[tex]2*a*x/(2*a) = \frac{\pm \sqrt{b^2 -4*a*c} - b}{2*a}[/tex]

[tex]x = \frac{\pm \sqrt{b^2 -4*a*c} - b}{2*a}[/tex]

Step-by-step explanation:

The Surface area of bar is 7696 square mm.

The area is the area occupied by a two-dimensional flat surface. It has a square unit of measurement. The surface area of a three-dimensional object is the space taken up by its outer surface. Square units are used to measure it as well.

We have,

The base was an equilateral triangle with a side of 16 mm and the bar was 155 mm long.

So, Surface area of Triangular Prism

= ( 16 + 16 + 16) 155 + 16  x 16

= 7440 + 256

= 7696 square mm

Each stripe is 1/18 yards thick, and the fence post if 5/6 yards. Therefore, we have to find how many 1/18s can go into 5/6. Thus, this is a matter of division, and we do 5/6 divided by 1/18 to find how many stripes we can have.

5/6 ÷ 1/18 = 5/6 * 18 = 15

Thus, the answer is D.

4) A is 3, which means we substitute all the "a"s in the expression for 3. Thus we have:

99 - 7(3)^2

99 - 7(9)

99 - 63 = 36

Therefore, it is 36.

Answer:

x = 2

Step-by-step explanation:

2x−3-x+4=3

combine like terms:

x + 1 = 3

x = 2

The equation is true for the value of x = 2.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given equation is as given below.

2x − 3 - x + 4 = 3

We have to operate the like terms together.

Here 2x and x are like terms and 3 and 4 are like terms.

(2x - x) - 3 + 4 = 3

x - 3 + 4 = 3

x + 1 = 3

Subtracting 1 on both sides,

x = 3 - 1

x = 2

Hence the equation is true for x = 2.
