If an objects mass is 10kg what is it’s weight?

Answer:

-22d -102

Step-by-step explanation:

8(−5d−9)−3(−6d+10)

Distribute

-40d -72 +18d -30

Combine like terms

-40d +18d   -72 - 30

-22d -102

Answer:

−22d − 102

Step-by-step explanation:

8 (−5d − 9) −3 (−6d + 10)

expand 8 (−5d − 9)  to  −40d − 72

= −40d − 72 − 3 (−6d + 10)

expand − 3 (−6d + 10)   to   18d − 30

= −40d − 72 + 18d − 30

combine like terms

= −40d + 18d − 72 − 30

=  −22d − 102

Answer:

x=−1,−7

Step-by-step explanation:

Answer:

The solutions are {-1, 9}

Step-by-step explanation:

x² - 8x + 16 can be re-written as (x - 4)^2, and 9 + 16 as 25.

Taking the square root of both sides of (x - 4)^2 = 25, we get:

x - 4 = ±5, or:

x = 4 + 5 = 9, and

x = 4 - 5 = -1

The solutions are {-1, 9}

Answer:

B. 8(3+1)

Explanation: 8x3 = 24. 8x1 = 8

Answer:

B. 8(3+1) = 32

Step-by-step explanation:

8 x 3 + 8 x 1 = 32

A. 8(3 + 8) = 88

B. 8(3+1) = 32

C. 3(8+1) = 72

D. 1(3+8) = 11

Answer:

(-1,-2)

Step-by-step explanation:

Ordered pairs go in the order x,y so the 2x would be the first number that then equals the second number. The answer is (-1,-2) because when you multiply 2*-1 you get -2 and what's the y? -2. Does -2 = -2? Yes.

Answer:

Step-by-step explanation:

A Chi-square test is used to test the test of independence between rows and columns, contingency tables. It is a test related to frequencies. The observed frequency is a given statistical frequency known as the actual frequency,  the expected frequency is known as the theoretical frequency is derived from the study by using the sum total of the row and total in the column divided by their corresponding sample size.

Answer:

Step-by-step explanation:

The column has the shape of a cylinder hence the formula for the volume of a cylinder is

[tex]v=\pi r^2h[/tex]

Given

diameter d= 390 mm

radius r= 390/2= 195 mm to meter = 0.195 m

length or height h= 3 m

applying the data to the formula we have

[tex]v=\pi *0.195^2*3\\\\ v=\pi*0.0038*3\\\\ v=\pi*0.0114\\\\ v=0.035 m^3[/tex]

we can now use the volume in addition with the density given to solve for the mass using the expression for density

density= mass/volume

2.45= mass/0.035

mass= 2.45*0.035

mass= 0.085 mg

We know that weight

w= mass* acceleration

w= 0.085*9.81

w= 0.83 N

Answer:

A. y = -4x - 10

Step-by-step explanation:

See image below. The red line (y = -4x - 10) is parallel to                                  the blue line (y = -4x + 3) and passes through (-3 , 2)

Answer:

y = -4x - 10 (Answer A)

Step-by-step explanation:

Any line parallel to the given y = -4x + 3 has the same slope:  -4.

Starting with y = mx + b, and substituting -4 for m, -3 for x and 2 for y, we get:

2 = -4(-3) + b, or b = -10, and so the desired equation is

y = -4x - 10 (Answer A)

Answer:

Step-by-step explanation:

 let us apply the interpolation formula to solve this problem

we have

[tex]\frac{y-y1}{x-x1} =\frac{y2-y1}{x2-x1}[/tex]

Now let us set the values to the notation above

x= $1.20

x1= $2.20

x2= $1.50

y = 50 cones

y1= 30 cones

y2= ?

[tex]y2= \frac{(y-y1)}{(x-x1)} (x2-x1)+y1[/tex]

Substituting our given data we have

[tex]y2= \frac{(50-30)}{(1.2-2.2)} (1.5-2.2)+30\\\\y2= \frac{20}{-1} (-0.7)+30\\\\y2= (20*0.7)+30\\y2= 14+30\\y2= 44[/tex]

the demand at a price of $1.50 per cone is 44 cones

Answer:

The answer is below

Step-by-step explanation:

Different countries have different metric system of measurement, but the metric system of measurement accepted all over the world is the international system of unit (SI unit)

1 quintal =  220.462 lbs and 1 bushel of corn = 56 lbs.

151 q/ha = (151 × 220.462) lbs/ha = 33289.762 lbs/ha

But 1 hectare = 2.471 acre, hence:

33289.762 lbs/ha = [tex]\frac{33289.762\ lbs}{1\ ha*\frac{2.471\ acre}{1 \ ha} } =13472.182\ lbs/acre[/tex]

Since 1 bushel of corn = 56 lbs, hence:

[tex]13472.182\ lbs/acre=\frac{13472.182\ lbs*\frac{1\ bushels}{56\ lbs} }{acre}=240.6\ bushels/acre[/tex] = 240.6 bu/ac

For a Margin of Error: +/- 1 bu/ac, the bushels per acre = (239.6 bu/ac, 241.6 bu/ac)

Answer:

B

Step-by-step explanation:

3.2 * 10⁷ + 6.4 * 10⁷

= 10⁷  * (3.2 + 6.4)

= 10⁷ * 9.6

= 9.6 * 10⁷

Answer:

The Atlantic Ocean and Pacific Ocean covers about 9.6 x 10^7 mi^2

Step-by-step explanation:

Let

x -----> area covered by the Atlantic Ocean

y -----> area covered by the Pacific Ocean

we know that

The area that covers the Atlantic Ocean and Pacific Ocean is equal to the sum of  the area covered by the Atlantic Ocean and the area covered by the Pacific Ocean

x = 3.2 x 10^7

y = 6.4 x 10^7

Substitute

x + y = 3.2 x 10^7 + 6.4 x 10^7 = 9.6 x 10^7.

Hope this helps!  And good luck on your test!

Answer:

d = 6 days

Step-by-step explanation:

We only have a total of 30 gallons.

We are told that we use 5 gallons per day.

So:

d - days

5d = 30

*Divide both sides by 5*

d = 6

Answer:

375

Step-by-step explanation:

The ratio of d to 125 is the ratio of 30 to 10,so by comparison, 30:10=3÷1

X÷125=X=375

Answer:

Step-by-step explanation:

Area of a rectangle = l × w

where

l is the length

w is the width

From the question

length = 99 m

width = 87 m

Substitute the values into the above formula and solve for the area

That's

Area = 99 × 87

We have the final answer as

Area = 8613

Answer:

  3. 6x -3 +4 = 7

  4. 6x +1 = 7

  5. 6x = 6

  6. x = 1

Step-by-step explanation:

3. The distributive property allows you to eliminate parentheses by multiplying the outside factor by every term inside.

  3(2x -1) +4 = 7 . . . . . . given

  3(2x) +3(-1) +4 = 7 . . . . using the distributive property

  6x -3 +4 = 7 . . . . . . . finishing the evaluation of those products

__

4. The only like terms that can be combined are the two constant terms on the left side. We simply add them up.

  6x +1 = 7

__

5. Using the subtraction property of equality, we can subtract 1 from both sides of the equation. We choose to do this so that the x-term is by itself.

  6x +1 -1 = 7 -1

  6x = 6

__

6. Using the division property of equality, we can divide both sides of the equation by 6. We choose to do this so the new coefficient of x is 1.

  6x/6 = 6/6

  x = 1

Additional comment

You're told to apply these steps without any explanation as to why or what the goal may be. We assume you're supposed to realize that you can use these steps to solve the equation. Of course, you can use different values for addition (or subtraction) or multiplication (or division). Doing so may satisfy the literal interpretation of the question, but won't get you a solution to the equation.

Answer:   143.8 units²

Step-by-step explanation:

Since you know the length of two sides and the measure of the included angle, you can use the following trig formula:

[tex]Area=\dfrac{1}{2}ac \sin B[/tex]

Given: a = 14, c = 21, B = 87°

[tex]Area=\dfrac{1}{2}(14)(21) \sin 87^o\\\\.\qquad =147\sin 87^o\\\\.\qquad =143.8[/tex]

Answer:

[tex]\huge \boxed{\mathrm{146.8 \ units^2 }}[/tex]

Step-by-step explanation:

We can solve for the area of the triangle when two sides are given and the angle in between the two sides.

[tex]\displaystyle A=\mathrm{\frac{1}{2}ac \cdot sinB }[/tex]

[tex]\displaystyle A=\mathrm{\frac{1}{2} \cdot 14 \cdot 21 \cdot sin87 }[/tex]

[tex]\displaystyle A=\mathrm{147 \cdot sin87 }[/tex]

[tex]\displaystyle A=\mathrm{146.79854160...}[/tex]

The area of the triangle is 146.8 units².

Answer:

[tex]F = 9.75cm[/tex]

Step-by-step explanation:

Given

In ABC;

[tex]C = 3.9cm[/tex]

[tex]Dilation = 2.5[/tex]

Required

Determine side F

In the given question;

DEF is a dilation of ABC

Comparing both triangles side by side,

Side F is a direct dilation of side C and this is calculated as follows

[tex]F = Dilation * C[/tex]

[tex]F = 2.5 * 3.9cm[/tex]

[tex]F = 9.75cm[/tex]

Answer: [tex]x=-2/3[/tex]

Subtract 24x from both sides

[tex]6x-6-24x=24x+6-24x\\-18x-6=6[/tex]

Add 6 to both sides

[tex]-18x-6+6=6+6\\-18x=12[/tex]

Divide both sides by -18

[tex]-18x/-18=12/-18\\x=-2/3[/tex]

Answer: x=-2/3.

Step-by-step explanation:6x-6 = 24х+6                                                                          

6x-6-24x=6                                                                                                                                 -18x-6+6=6+6                                                                                                                               -18x/-18=12/-18                                                                                                                                x=-2/3
