Answer:

Part 1:

Due to these magnitudes are too big, it is better to use km as a unit of diameter measurement.

Part 2:

The diameter of the sun is approximately 109 times the diameter of the earth.

Step-by-step explanation:

Part 1:

Due to these magnitudes are too big, it is better to use km as a unit of diameter measurement.

So we can rewrite the diameter of the Earth in terms of km, knowing that 1 km = 1000000 mm.

[tex]D_{E}=1.2742\times 10^{10}mm*\frac{1km}{1000000mm}=1.2742\times 10^{4} km[/tex]

Part 2:

We can divide each diameter to find the relation between them.

[tex]\frac{D_{S}}{D_{E}}=\frac{1.391\times 10^{6} km}{1.2742\times 10^{4} km}=109.2[/tex]

Therefore the diameter of the sun is approximately 109 times the diameter of the earth.

Answer:

Isabella bought 70.19 ounces of dark chocolate.

Step-by-step explanation:

You want to subtract the total which is 71.4 minus the 1.21 ounces of the white chocolate, you then will get 70.19 ounces of dark chocolate. To be sure, you can add 70.19+1.21 and will get you the total amount of ounces of chocolate. Hope this helps :D

Answer:

[tex] \huge \: x = - 5417.33[/tex]

Step-by-step explanation:

[tex]0.75 (x + 200) = 150.5 (2 – 28) \\ [/tex]

Expand the terms and simplify

That's

[tex]0.75x + 150 = 301 - 4214 \\ 0.75x + 150 = - 3913[/tex]

Subtract 150 from both sides of the equation

[tex]0.75x + 150 - 150 = - 3913 - 150 \\ 0.75x = - 4063[/tex]

Divide both sides by 0.75

[tex] \frac{0.75x}{0.75} = - \frac{4063}{0.75} \\ x = - 5417.333333[/tex]

We have the final answer as

Step-by-step explanation:

So you will start from the decimal and move 8 places to the left.

E-8 is the same as 10^-8 so you will move to the left

If it was E8 you would move to the right 8 places.

Answer:

The length of AB is 3 squares

Length of A' B' is 9 squares

Point A is (2,1)

Point a' is ( 6,3)

Step-by-step explanation:

I am not sure what the scale factor is though. I have never heard of it. Sorry!

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x−2−7x=10x+4

3x+−2+−7x=10x+4

(3x+−7x)+(−2)=10x+4(Combine Like Terms)

−4x+−2=10x+4

−4x−2=10x+4

Step 2: Subtract 10x from both sides.

−4x−2−10x=10x+4−10x

−14x−2=4

Step 3: Add 2 to both sides.

−14x−2+2=4+2

−14x=6

Step 4: Divide both sides by -14.

−14x−14=6−14

x=−3/7

Answer:

x=−3/7

The  value of x is -3/7.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

3x-2-7x = 10x + 4

Now, solving for x

3x-2-7x = 10x + 4

-4x - 2= 10x + 4

-4x - 10x = 4 + 2

-14x = 6

x= -6/14

c= -3/7

Hence, the value of x is -3/7.

Answer:

$3.00; $7.29

Step-by-step explanation:

Find what 8% of $37.50 is:

x/37.50 = 8/100

cross multiply

x × 100 = 37.50 × 8

100x = 300

divide both sides by 100

x = 3

$3 is 8% of $37.50

If 8% was added to the bill, then add $3 to $37.50

3.00 + 37.50 = 40.50

Now find what 18% of 40.50 is

x/40.50 = 18/100

cross multiply

x × 100 = 40.50 × 18

100x = 729

divide both sides by 100

x = 7.29

$7.29 is 18% of the bill after sales tax

They tipped $7.29

Step-by-step explanation:

1.) x + 37 + x + 67 + 90 = 180

combine like terms

2x +194 = 180

subtract 194 both sides

2x = -14

x = -7

2.) 63 + 86 = x

x = 149

Answer:

1. (x+37) + (x+67) + 90° = 180°

=> x + x + 37 + 67 + 90 = 180

=> 2x +194 = 180

=> 2x = 180 –194

=> 2x = –14

=> x = –14/2

=> x = –7

2. [The measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles. ]

x = 63° + 86°

=> x = 149°

<PQR=134

<SQR=46

Answer:

[tex]\boxed {\angle PQR = 134\textdegree}[/tex]

Step-by-step explanation:

Both angles are Supplementary (Two angles that add up to 180°). So, write an expression using the following measurements of both [tex]\angle PQR[/tex] and [tex]\angle RQS[/tex] and 180:

[tex]\angle PQR = 3x + 5[/tex]

[tex]\angle RQS = x + 3[/tex]

[tex]3x + 5 + x + 3 = 180[/tex]

Solve:

[tex]3x + 5 + x + 3 = 180[/tex]

[tex]4x + 5 + 3 = 180[/tex]

[tex]4x + 8 = 180[/tex]

[tex]4x + 8 - 8 = 180 - 8[/tex]

[tex]4x = 172[/tex]

[tex]\frac{4x}{4} = \frac{172}{4}[/tex]

[tex]x = 43[/tex]

-After you have the value of [tex]x[/tex], use it to the expression of [tex]\angle {PQR}[/tex] to get the actual answer of [tex]\angle PQR[/tex]:

-The value of [tex]x[/tex]:

[tex]x = 43[/tex]
