Answer:

1. 1, 9/4

2. 4^4

3. -0.0000000008723

4. -5100023*10^2, -6.6*10^(12)

Step-by-step explanation:

[tex]21^0 = 1;\ n^0\ always\ is\ 1.\\(\frac{2}{3})^{-2} = (\frac{3}{2})^2 = \frac{3^2}{2^2} = \frac{9}{4}; n^m\ is\ performed\ by\ doing\ n*n,\ m\ times.\\i.e.,\\ n^2=n*n;\\n^3=n*n*n;\\ n^4=n*n*n*n\\\\\frac{4^6}{4^2};\ original\\\\\frac{(4^2)^3}{4^2};\ (n^{mc}\ can\ be\ rewritten\ as\ (n^m)^c\\\\\frac{4^2}{4^2}*\frac{(4^2)^2}{1};\ split\ the\ fraction\ into\ two\ parts\ because\ of\ multiplication\ rules.\\\\1*4^4;\ \frac{n}{n}\ can\ be\ written\ as\ 1.\ \frac{n}{1}\ can\ be\ written\ as\ n.\\\\4^4[/tex]

Technically, [tex]4^4[/tex] is 256, but the answer is requested as a number with an exponent.

-8.723 * 10^-10 would be -0.0000000008723.

10^-10 = [tex]\frac{1}{10^{10}}[/tex], which would mean you must move your decimal left by the number of places indicated by the exponent.

[tex]-5.1*10^8-2.3*10^3 = x\\-51*10^7-23*10^2 = x\\10^7=10^{5+2}=10^5*10^2\\-5100000*10^2-23*10^2=x\\-5100023*10^2=x;\ combine\ like\ terms.\\-6*10^5 * 1.1*10^7 = x\\-6*1.1*10^5*10^7;\ rewrite\ for\ simplification.\\-6.6*10^{12}=x[/tex]

Using the together rate, it will take more 3.45 days to complete the work.

Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

The together rate is given by the sum of each separate rate.

For this problem, the rates are given as follows,

Ann,1/10 = 0.1

Ben,1/12 = 0.0833

Together,1/x

Hence the amount completed in 2 days is:

2 x (0.1 + 0.0833) = 0.3666

The amount it would take them to complete 100% of the project working together is found by the together rate as follows,

x = 60/11

x = 5.45 days.

The time it would take to do the remaining 100 - 36.66 = 63.34% of the project is,

0.6334 x 5.45 = 3.45 days.

It will take more 3.45 days to complete the work.

Answer:333R1 or as a mixed fraction 33 1/3. I believe this is right :]

Step-by-step explanation:

The given equation of the straight line is y +8x+10=0

We are required to find the equation of a straight line passing  through the point (-2, 6) and has a slope of -8.

An equation of a straight line can be easily found if the slope and any of the points is given

The general form of equation is given by

y-y1 = m (x-x1)

where x1,y1 is the coordinate of the known point

m is the slope of the line

It is given that the coordinate of the known point is (-2,6)

the slope is given to be -8

Thus using these values to form the equation,

y-6 = -8 (x--2)

y-6 = -8 (x+2)

y-6 = -8x-16

y+8x-6+16=0

y+8x+`10=0

Hence, The straight line equation is y +8x+10=0

Answer:

64.75

Step-by-step explanation:

The total heights of men is m

so m/15 = 69.65 => m = 1044.75

The total heights of all students is s

so s/35 = 66.85 => s = 2339.75

so the total heights of women = 2339.75 - 1044.75 = 1295

The mean height of women = 1295/20 = 64.75

Therefore, on dividing 6216 by 21 we get 126

Given 6216 / 21

21 ) 6216 ( 296

Answer:

38363

Step-by-step explanation:

Modelling the situation, it is found the price of the ticket without the coupon is of $9 when all the six friends spent $ 42 to buy the tickets.

Total money spent by 6 friends on purchasing of the movie tickets = $ 42

So, the money spent for the purchase of 1 ticket will be calculated by dividing the $ 42 by 6.

So, cost of 1 ticket = 4 42 / 6 = $ 7

Coupon is of $2-off.

This means that with the coupon, $2 is subtracted from the ticket price.

So, price of ticket will be = $ 7 + $ 2 = $ 9.

Therefore, the price of the ticket without the coupons will be $ 9.

we get that, the value of x for the given angles in the diagram is 10°.

We can see that:

∠  NMG + ∠ GML = ∠ NML

Substituting the values of the angles in the equation, we get that:

46 ° + 8 x - 5° = 11 x + 11 °

Combining the like terms:

8 x + 41° = 11 x + 11°

Taking variables on one side:

11 x - 8 x = 41° - 11°

Combining the like terms again:

3 x = 30°

Divide both sides by 3:

x = 30° / 3

x = 10°

Therefore, we get that, the value of x for the given angles in the diagram is 10°.

-5 and 7 are real and rational numbers also they are integers.

Numbers which can be written in the form of p/q are rational numbers where q must not be zero.

According to the given question we have to determine what kind of numbers are -5 and 7.

In a most simple way we can say that - 5 is an negative integer and 7 is a positive integer.

But -5 can be written as -5/1 which is a rational number also and 7 can also be written as 7/1 so we can also say they are integers al well as rational numbers.Lastly they are real numbers as they don't have any imaginary part 'i' in it.

Step-by-step explanation:

You want the smallest angle of a triangle in which the other two angles are 20 degrees larger than the smallest, and 3 times the smallest.

The sum of angles is 180 degrees. The three angles are x, (x+20), and (3x). Their sum is ...

  x +(x +20) +3x = 180

Collecting terms gives ...

  5x +20 = 180

Answer: see explanation

Step-by-step explanation:

The 10 cm distance is measured perpendicularly to the chord, forming a right angle and bisecting the chord. Thus half of the chord, the segment from the center of the chord, and a radius to the end of the chord form a right triangle. The hypotenuse is 26 cm and one leg is 10 cm, so the other leg is given by the Pythagorean theorem: a^2 + 10^2 = 26^2, giving a = 24 cm. Since a is half the chord, the chord is 2a = 48 cm in length.

Hence, the length of a chord of a circle is [tex]48cm[/tex].

What is the circle?

A circle is defined as a two-dimensional figure, which is round in shape where all the points on the surface of the circle are equidistant from the center point is called “[tex]P[/tex]”.

Here given that,

A circle of radius [tex]26[/tex]cm if the chord is [tex]10[/tex]cm from the center of the circle.

So,

The  [tex]10[/tex]cm from the center of the circle is perpendicular of the chord and the hypotenuse is  [tex]26[/tex]cm .

As we know

[tex]H^2=B^2+P^2[/tex]    .......[tex](1)[/tex]

Substituting the values in the equation [tex](1)[/tex], we get

[tex](26)^2=(10)^2+B^2\\B^2=676-100\\B^2=576\\B=\sqrt{576}\\B=24cm[/tex]

Hence, the length of a chord of a circle is [tex]48cm[/tex].

Answer: 2.95 I think

Step-by-step explanation:

The slope-point form is y + 1 = (1/4) (x +2)

The function notation for the point-slope form is f(x) = -1 + (1/4) (x +2)

From the graph, we get two points (x₁, y₁) = (-2, -1) and (x₂, y₂) = (2,0)

Slope, m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

               = [tex]\frac{0 --1}{2--2}[/tex]

               = 1/4

The slope-point form of a line is (y-y₁) = m(x-x₁), where (x, y) is the general point on the line, (x₁, y₁) is a given point on the line and m, the slope of the line.

So here the slope-point form of the line is,

(y- -1) = 1/4(x- -2)

⇒ y + 1 = (1/4) (x +2)

For the function notation, we put y = f(x) simply and write it as,

f(x) = -1 + (1/4) (x +2)

The set of ordered pairs that represents a function is the third option.

{ (4, 1), (-6, 6), (5, -2), (-4, 1)}

For a relation that maps elements x (inputs) into elements y (outputs), we will have ordered pairs of the form (x, y) that define the relation.

Now, a relation is only a function if input are only mapped to only one output.

For example, if you look at the first set of ordered pairs, you can see that the input x = -4 appears twice with two different outputs, then this relation does not represent a function.

For the second set the same thing happens for the input x = -8, and for the last set the same happens for the input x = -8

The only set where each input appears only once is the third one:

{ (4, 1), (-6, 6), (5, -2), (-4, 1)}

This relation represents a function, so this is the correct option.
