Step-by-step explanation:

3(2−x)=−6

Step 1: Simplify both sides of the equation.

3(2−x)=−6

(3)(2)+(3)(−x)=−6(Distribute)

6+−3x=−6

−3x+6=−6

Step 2: Subtract 6 from both sides.

−3x+6−6=−6−6

Use the given circle. Find the length s to the nearest tenth.

a) 10.5 in
b) 5.2 in
c) 3.3 in
d) 20.9 in

Answers

Answer: its A

Step-by-step explanation:

Any smooth curve connecting two points is called an arc. The length of arc s to the nearest tenth is 10.5 in.

What is the Length of an Arc?

Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,

[tex]\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]

where θ is the angle, which arc creates at the center of the circle in degree.

The length of the given arc s, with an angle made at the center equal to (2/3)π and radius of 5 inches can be represented as,

[tex]\text{Length of Arc} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]

[tex]\text{Length of Arc s} = 2\pi \times (5)\times \dfrac{\frac23\pi}{2\pi}[/tex]

                        [tex]=10.472\approx 10.5\rm\ in[/tex]

Thus, the length of arc s to the nearest tenth is 10.5 in.

Step-by-step explanation:

In a right angled triangle:  the square of the hypotenuse is equal to

the sum of the squares of the other two sides.

[tex]8^{2} + 8^{2} = x^{2}[/tex] (x is the hypotenuse)

Answers

Answer:

c

Step-by-step explanation:

Answer:

399,876

Step-by-step explanation:

So, 400,000 DVD sales with a 31% decline means in the first year following, there will be a decline of 124,000 DVDs sold. So we need to take 400,000-124,000 which equals a starting point for your two is 276,000 dvds. Then, add 123,876, which gives you 399,876.

Pythagorean Theorem: How many yards will the players have to run?

Answers

Answer:

≈ 125.3

Step-by-step explanation:

If we're using the Pythagorean Theorem to solve this, then the formula is:

[tex]a^{2}+ b^{2} =c^{2}[/tex]

So basically, by using this formula, you're finding the length that the soccer players will run diagonally. Plug in the numbers:

[tex]110^2 + 60^2 = c^2[/tex]

12100 + 3600 = [tex]c^2[/tex]

15700 = [tex]c^2[/tex]

Take the square root:

15700 = [tex]c^2[/tex]

[tex]\sqrt{15700} = \sqrt{c^2}[/tex]

125.3 ≈ c

elijah's credit card statement showed these items: Last Balance Payments Finance Rate New Charges $152.58 $45.00 1.5% $213.40 What is Elijah's new balance? $320.98 $322.59 $323.27 $397.51

Answers

Answer:

Option A,$320.98  is correct

Step-by-step explanation:

The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.

last balance as shown by the statement was $152.58

new charges were $213.40

payment made by Elijah was  $45

new balance=$152.58+$213.40-$45=$320.98

The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.

Answer:

Other answer is incorrect. Elijah's new balance would be $322.59

Hello there i hope you are having a great day :) Your Question : Michael has $10 in his savings account. Option 1 will add $100 to his account each week. Option 2 will double the amount in his account at the end of each week. Michael wants to have at least $700 in his account at the end of 7 weeks to buy a mountain bike.

Option 1 puts $100 in each week so 7 weeks would equal to 7 weeks x $100 = $700 that would equal the amount for the bike in 7 weeks or Option 2 Will double the amount in hes account each week so $10 x 2 = $20. 1 week $20 2 week $40 3 week $80 4 week $120 5 week $240 6 week $480 7 week $960. So the Option two Is the best one as Option one would equal to $700 and Option two $960 that would equal left over $260. Hopefully that helps you ❤
