What can you do if a decimal product has final zeros to the right of the decimal point
Answer:
place the decimal point in the product so that the number of decimal places in product is the sum of decilal places in the factors. keep all zeros in the product when you place the decimal point. you can drop the zeros on the right once the decimal point has been placed in the product.

PLEASE HELP I AM STUCK
Answer:
1/2 pound

Step-by-step explanation:
4 divided by 2 is 2 and 1 pound divided by 2 is 0.5.
Find all values of c such that 3^2c+1=28*3^c-9. If you find more than one value of c, then list your values in increasing order
[tex]3^{2c} + 1 = 28\times3^c - 9 \implies 3^{2c} - 28\times3^c = -10[/tex]
Complete the square on the left side:
[tex]3^{2c} - 28\times3^c = \left(3^{2c}-28\times3^c+14^2\right)-14^2 = \left(3^c-14\right)^2 - 196[/tex]
Then the equation becomes
[tex]\left(3^c-14\right)^2 - 196 = -10 \\\\ \left(3^c-14\right)^2 = 186 \\\\ 3^c - 14 = \pm\sqrt{186} \\\\ 3^c = 14\pm\sqrt{186}[/tex]
Both 14 + √186 and 14 - √186 are positive numbers, so we can take the logarithm (base 3) of both sides without issue:
[tex]\log_3\left(3^c) = c = \log_3\left(14\pm\sqrt{186}\right)[/tex]
Then in increasing order, the solutions are
c = log₃(14 - √186), c = log₃(14 + √186)
You have 3 fair 6-sided dice. You repeatedly roll all 3 at once, until all 3 of them show thesame number. What is the probability that you have to tryat leasttwice
Answer:
35/36 or about 0.972
Step-by-step explanation:
The probability of rolling the same number
first die 6/6
second die 1/6
third die 1/6
1(1/6)(1/6) = 1/36
so there is a 35/36 chance that you will not get it done on the first roll and need to attempt at least one more time.

What is x and the unknown angle? May I also get a brief explanation of how to do it?
Answer:
149+(13x+5)=180
154+13x=180
13x=26
x=2
Answer:
see explanation
Step-by-step explanation:
The 2 angles are adjacent on a straight line and sum to 180° , then
149 + 13x + 5 = 180 , that is
154 + 13x = 180 ( subtract 154 from both sides )
13x = 26 ( divide both sides by 13 )
x = 2
Then
unknown angle = 13x + 5 = 13(2) + 5 = 26 + 5 = 31°

Solve the following expression when
k= 12
(4k + 2) = 10
Answer:
5
Step-by-step explanation:
(4k + 2) ÷ 10
(4(12) + 2) ÷ 10
(48 + 2) ÷ 10
(50) ÷ 10
= 5
Hope this helps!! <3
The solution to the expression (4k + 2 ) ÷ 10 when k = 12 is 5
From the given expression, we are to solve for (4k + 2) ÷ 10
When
k = 12What we are going to do is that we will replace k with 12 wherever we see (k) in the expression given
∴
= (4k + 2 ) ÷ 10
= (4(12) + 2 ) ÷ 10
= (48 + 2) ÷ 10
= (50) ÷ 10
= 5

A rectangles length is 6 units greater than its width. Write an equation expressing the rectangles area, A, as a function of W
Answer:
A = W² + 6W
Step-by-step explanation:
The width is W.
The length is 6 units greater than the width, so the length is W + 6.
The area is the product of the length and width.
A = (W + 6)W
A = W² + 6W

you are solving an equation with a variable on each side. does the side on which you choose to isolate the variable affect the solution? why might you choose one side over the other?
Answer:
Does the side on which you choose to isolate the variable affect the solution?
No, because at the end you get an equation with a variable on one side only.Why might you choose one side over the other?
To simplify or minimize the number of operations you need. Moving part of the terms from one side to another adds at least one extra operation and it may also bring some complications.The area of a rectangle is represented by 9× + 15 and the length of the rectangle is 3.

Sin theta = 3/4, what are the values of cos theta and tan theta?
Answer:
[tex]\displaystyle \cos(\theta) = \frac{\sqrt{7}}{4}[/tex].
[tex]\displaystyle \tan(\theta) = \frac{3\sqrt{7}}{7}[/tex].
Step-by-step explanation:
By the Pythagorean identity, for any given angle [tex]\theta[/tex], [tex]\sin^{2}(\theta) + \cos^{2}(\theta) = 1[/tex].
Given that [tex]\displaystyle \sin(\theta) = 3/4[/tex], solve this equation for [tex]\cos(\theta)[/tex].
[tex](\sin(\theta))^{2} + (\cos(\theta))^{2} = 1[/tex].
[tex]\displaystyle \left(\frac{3}{4}\right)^{2} + (\cos(\theta))^{2} = 1[/tex].
[tex]\begin{aligned} \cos(\theta) &= \sqrt{1 - \frac{9}{16}} \\ &= \sqrt{\frac{7}{16}} \\ &= \frac{\sqrt{7}}{4} \end{aligned}[/tex].
The tangent of an angle is equal to the ratio between the sine and cosine of that angle. In this question:
[tex]\begin{aligned} \tan(\theta) &= \frac{\sin(\theta)}{\cos(\theta)} \\ &= \frac{3/4}{\sqrt{7}/4} \\ &= \frac{3}{\sqrt{7}} \\ &= \frac{3\sqrt{7}}{7}\end{aligned}[/tex].

James is selling a bike on an internet auction website. he pays £1.45 insertion fee, £2.85 for an enhanced advert and a selling fee of £1.95 when the bike is sold. what are his total selling fees to the nearest pound (£)
Hello :D
£1.45 + £2.85 = £4.30
£4.30 + £1.95 = £6.25
£6.25 to the nearest pound = £6.00
Answer: Selling fees = £6 (rounded to the nearest pound)
Step-by-step explanation:
Given information
Insertion fee = £1.45
Enhanced advert = £2.85
Selling fee = £1.95
Given expression deducted from the given information
Total = insertion + enhanced advert + selling
Substitute values into the expression
Total = (1.45) + (2.85) + (1.95)
Simplify by addition
Total = 4.3 + (1.95)
Total = 6.25
