Answer:

1/4 of the work

Step-by-step explanation:

A quarter (1/4) of the work is done in 2 days. Let's break it down:

Work can be finished in 8 days total so with 2 days it is only partially completed. If we set it up as 2/8 we can simplify to get 1/4. Therefore, we know only a quarter of the work is done so far.

Step-by-step explanation:

First things first put them under a square root sign

Second think about what squared can go into that number

Third if there’s a number that can go into it and there’s leftover numbers like if your square rooting 18 you’ll take the number put them under the square root and take whatever can be squared like the 9 and turn it into is squared counter part the three so it’ll look like (is shown in the picture equation below).

Using two points:

Since we are given the [tex]y[/tex] and [tex]x[/tex] value, what is left is the [tex]m[/tex] and [tex]b[/tex] in the formula, which represent slope and the y-intercept.

No, both temperatures are positive numbers and not the same distance from 0, so they cannot be opposites. Both numbers have to be the same distance from zero, but one has to be above zero and the other has to be below zero in order to be opposites.

The conclusion made by Sarah is correct.

We have Sarah notices that her room's temperature is 4°F above the recommended temperature, and the downstairs bedroom's temperature is 4°F below the recommended temperature. She graphs 72 and 64 on a vertical number line and determines they are opposites.

Yes she is correct. The recommended temperature is 68. She marked -

(68 + 4) = 72 and (68 - 4) = 64 on the scale. So, she is correct.

Therefore, the conclusion made by Sarah is correct.

A. about 800 points

Step-by-step explanation:

how is this possible

Sin theta, cosine theta and tangent theta are the angle of trigonometry.

What are the angle in trigonometry?

There are total six angles in the trigonometry which are sin theta, cosine theta,  tangent theta, cotangent theta, secant theta, co secant theta.

Given information-

The value of the cosine theta given in the problem is 0.3090.

It can be written as,

[tex]\cos\theta=0.3090[/tex]

To find the value of theta, took the cosine function to other side of the equation.

This will make the cosine angle as arc cosine. Thus,

[tex]\theta=\cos^{-1}(0.3090)[/tex]

Solve it further as,

[tex]\theta=72^o[/tex]

Hence the value of the angle is 72 degrees.

Use this value to fine the angle of sin theta and tangent theta.

            [tex]\sin72^o=0.9511[/tex]

        Hence, the value of sine theta is 0.9511.

          [tex]\tan72^o=3.078[/tex]

        Hence, the value of tangent theta is 3.078.

Answer:

$97.20

Step-by-step explanation:

he pays 90 dollars for the jacket

sales tax is 8% of the 90 dollars that he payed

so we can convert 8% to a decimal by moving the decimal 2 to the left. 8% to 0.08

now multiply 90*0.08 to find the sales taxes

90*0.08= 7.20

so we just add $7.20 to $90

and we get $97.20

Answer:

120

Step-by-step explanation:

the angle.of all of these is 180 and 35+25+X=180..

60+X=180...... X=120

The measure of angle D is equivalent to 120 degrees.

A triangle is a two - dimensional figure with three sides and three angles.

The sum of the angles of the triangle is equal to 180 degrees.

∠A + ∠B + ∠C = 180°

Given is that the measure of angle B is 25° and the measure of angle C is 35°.

For the triangle, we can write the measure of angle D as -

∠B + ∠C + ∠D = 180°

25° + 35° + ∠D = 180°

∠D = 180° - 60°

∠D = 120°

Therefore, the measure of angle D is equivalent to 120 degrees.

Shift constants from LHS to RHS, changing it's sign.

⇛-5x = 23 - 45 - 3

⇛-5x = 23 - 42

⇛-5x = -19

Shift the number 5 from LHS to RHS.

B)   x = 8[tex]\sqrt{3}[/tex] ;  y = 4[tex]\sqrt{3}[/tex]

Step-by-step explanation:

in a 30-60-90° triangle the sides, respectively, are in the ratio of

1 : [tex]\sqrt{3}[/tex] : 2

we can find 'x' by creating this proportion:

12/[tex]\sqrt{3}[/tex] = x/2

cross-multiply to get:

[tex]\sqrt{3}[/tex]x = 24

x = 24/[tex]\sqrt{3}[/tex]

we can simplify this by 'rationalizing the denominator' which is to

multiply numerator and denominator by [tex]\sqrt{3}[/tex] to get:

(24[tex]\sqrt{3}[/tex])÷3, which is 8[tex]\sqrt{3}[/tex]

we know that side 'y' is half that of side 'x'

therefore y = 4[tex]\sqrt{3}[/tex]

The sequence of the areas of the squares is a geometric progression,

and the sum to infinity can be determined by using a formula.

Correct responses:

a. 1,  0.5·√2,  0.5,  0.25·√2

b. 1, 0.5, 0.25, 0.125

c. The sum of the areas of the infinite squares is 2

Given;

Length of the side of the square = 1 cm.

The inscribed square is drawn by connecting the midpoints.

Pythagoras's theorem is; Hypotenuse² = Perpendicular² + Base²

Leg length of the second (inscribed) square = 1 ÷ 2 = 0.5

Side length of the second square = √(0.5² + 0.5²) = 0.5·√2

Leg length of the third square = 0.5·√2 ÷ 2 = 0.25·√2

Side length of the third square = √((0.25·√2)² + (0.25·√2)²) = 0.5

Leg length of the fourth square = 0.5 ÷ 2 = 0.25

Side length of the fourth square = √(0.25² + 0.25²) = 0.25·√2

The sequence of the sides of the first 4 terms is therefore;

(b) The sequence for the areas for the first 4 terms are;

1², (0.5·√2)², 0.5², (0.25·√2)², which gives;

c. The given sequence of the areas is a geometric progression, G.P.

Where;

The first term, a = 1

The common ratio, r = 0.5

The sum of a G.P to infinity is given as follows;

[tex]\displaystyle \sum \limits^{\infty}_{k = 0} a \cdot r^ k= \mathbf{ \dfrac{a}{1 - r}}[/tex]

Which gives;

[tex]\displaystyle \sum \limits^{\infty}_{k = 0} 1 \times \frac{1}{2} ^ {k}= \dfrac{1}{1 - 0.5}= 2[/tex]
