Answers
Answer:
$288
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 18%/100 = 0.18 per year,
then, solving our equation
I = 3200 × 0.18 × 0.5 = 288
I = $ 288.00
The simple interest accumulated
on a principal of $ 3,200.00
at a rate of 18% per year
for 0.5 years is $ 288.00.

1 1
x 1 1 (This is a right triangle)
1 69° 1
1-------------1
11
1. first identify a trigonometric ratio that will make it possible to find the value of x.
Answer = X is opposite to the angle 69° and 11 is adjacent to the angle 69°
2. To find the unknown value, which trigonometric function should be used?
Answer = Tangent
3. Use the tangent ratio for TAN 69°.
Answer = TAN 69° = [tex]\frac{x}{11}[/tex]
4. Multiply both sides by 11.
TAN 69° = [tex]\frac{x}{11}[/tex]
Answer = 11 · TAN 69° = x
5. Simplify
11 · TAN 69° = x
11(2.6051) ≈ x
(Blank) ≈ x
Answer = 28.7 ≈ x < -- (Rounded to the nearest tenth)
11(2.6051) ≈ x This is the part I'm having trouble with. I don't understand how to get the decimal in the parenthesis. I've tried dividing, multiplying, multiplying and then dividing. I just can't get the correct answer. I think I'm suppose to use a geometry calculator and input TAN then multiply(or divide I don't know), but I don't have one right now so I need to know if there's any way I could get the same answer with a regular calculator.

Dixie drinks 1/3 a cup of water in 1/6 of a minute. How many cups of water per minute does Dixie drink?
Answers
Hello, 928747! I can help.
So, we're trying to find out how many cups of water Dixie can drink per minute.
Since there are 60 seconds in a minute, we can assume that 1/6 of a minute is 10 seconds
1/6 = 10/60
So there are 60 seconds in a minute so we would multiply 1/3 by 6 to find how many cups she can drink in one minute
1/3 x 6 = 2
So, Dixie can drink 2 cups in one minute.

The blueprint of a concrete patio has a scale of 2 inches = 3 feet. On this blueprint, the width of the patio is 12 inches. You want to create a NEW blueprint using a scale of 1 inch = 2 feet. What will be the width of the patio on your new blueprint?
Answers
Answer:
[tex]9\ \text{inches}[/tex]
Step-by-step explanation:
[tex]2\ \text{inches}[/tex] of the blueprint is [tex]3\ \text{feet}[/tex] of the actual concrete patio.
So [tex]1\ \text{inch}[/tex] of the blueprint = [tex]\dfrac{3}{2}\ \text{feet}[/tex] of the actual concrete patio
Width of the patio in the blueprint is [tex]12\ \text{inches}[/tex].
So [tex]12\ \text{inches}[/tex] of the blueprint = [tex]12\times \dfrac{3}{2}=18\ \text{feet}[/tex] of the actual concrete patio.
Now for the new blueprint [tex]1\ \text{inch}=2\ \text{feet}[/tex] of the actual concrete patio.
[tex]1\ \text{feet}[/tex] of the actual concrete patio = [tex]\dfrac{1}{2}\ \text{inch}[/tex] of the new bluprint.
So, [tex]18\ \text{feet}[/tex] of the actual concrete patio = [tex]\dfrac{18}{2}=9\ \text{inches}[/tex] of the new blueprint.

Find the 13th term of the geometric sequence 3, -15, 75, ...
Answers
the terms of geometric sequence are 3, -15, 75
given,
1st term (a) = 3
second term (t2)=-15
common ratio (r) = t2/t1
=-15/3
=-5
then
t13= ar^n-1
=3×(-5)^13-1
=3×244140625
=3×244140625
=732421875.
The [tex]13^{th}[/tex] term of the geometric sequence is - 732421875.
A geometric sequence is given ; 3 , -15 , 75....
We have to find the [tex]13^{th}[/tex] term of the geometric sequence.
What is the formula for calculation of nth term of geometric Sequence ?
The formula for calculation of nth term of geometric progression is [tex]a_{n}[/tex] = [tex]a_{1}[/tex] × [tex](r)^{n-1}[/tex] where r is the common ratio of geometric sequence.
Given geometric sequence is 3 , -15 , 75....
and
Common ratio is r.
i.e., r = -15 ÷ 3 = -5
∵ [tex]n^{th}[/tex] term of a geometric sequence is given by ;
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] × [tex](r)^{n-1}[/tex]
where [tex]a_{1}[/tex] is the first term.
So,
[tex]13^{th}[/tex] term of the geometric sequence will be ;
[tex]a_{13}[/tex] = 3 × [tex](-5)^{12}[/tex]
[tex]a_{13}[/tex] = - 732421875
Thus , the [tex]13^{th}[/tex] term of the geometric sequence is - 732421875.

Alex paid 108.34 for groceries. Rounded to the nearest dollar, how did alex pay for groceries?
Answers
The rounded figure of the amount Alex paid at the groceries shop is $108.
What is rounding a figure?The process of replacing a number by another number of approximately the same value but having fewer digits is called rounding a figure.
Given that, Alex paid 108.34 for groceries. We need to round it to the nearest dollar,
We know that,
If the first decimal digit is 5 or more, we increase the whole part by one unit. For example, $34.57 rounded to the nearest whole dollar is $35.
If the first decimal digit is less than 5, we leave the whole part as it is. For example, $45.19 rounded to the nearest dollar is $45.
Here, the first decimal point is less than 5, therefore, we will leave the whole part as it is.
Hence, the rounded figure of the amount Alex paid at the groceries shop is $108.

n² + n² = (6√2)²
