Answer: 9 years
Step-by-step explanation:
Simple interest = PRT/100
where
P = principal = $2450
R = rate = 3.5%
T = time = unknown
Interest = $3221.75 - $2450 = $771.75
Simple interest = PRT/100
$771.5 = ($2450 × 3.5 × T)/100
$771.5 = $8575T/100
8575T = 771.5 × 100
8575T = 77150
T = 77150/8575
Time = 8.99 years = 9 years
How does 8 × 2 1 3 compare to 8? A) Less than 8 because you are multiplying by number less than 1. B) Greater than 8 because you are multiplying by a number less than 1. C) Less than 8 because you are multiplying by a number greater than 1. D) Greater than 8 because you are multiplying by a number greater than 1.
Answer:
Greater than 8 because you are multiplying by a number greater than 1.
Step-by-step explanation:
When 8 is multiple by another number, say x, the product is;
I) less than 8 if x<1
ii) equal to 8 if x=1
iii) greater than 8 if x> 1
Since 213 is greater than 1,then the product of 8 × 2 1 3 is greater than 8.

On a test, Marcus is asked to simplify . Here is his work:
√128 = √16 · √8 = 4√8
Which statement best describes Marcus' answer?
He is incorrect because 16 times 8 is not 128.
He is incorrect because he did not use the largest perfect square.
He is incorrect because the 4 and the 8 should be switched around in his answer.
He is correct.
Answer:
He did not use the largest perfect square
Step-by-step explanation:
4 [tex]\sqrt{8}[/tex] is the correct answer
What is square root ?
In mathematics, a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x. For example, 4 and −4 are square roots of 16, because 4² = ² = 16. The square root of any number can be expressed using the formula: √y = y½. In other words, if a number has 1/2 as its exponent, it means we need to find the square root of the number.
Given,
[tex]\sqrt{128}[/tex]
we divide the number 128 by 2 four times, we get
= [tex]\sqrt{8*2*2*2*2}[/tex]
= 2*2[tex]\sqrt{8}[/tex]
=4 [tex]\sqrt{8}[/tex]
Therefore, 4 [tex]\sqrt{8}[/tex] is the correct answer

who wants a brainist whats the how do you convert ratios
Answer:
To a whole number: Add the numbers in the ratio togetherTo a fraction: Each number in the ratio would become a numerator in a fractionI hope this helps!
Credit goes to: calculatorsoup.com
Answer:
To convert, start by adding both parts of the ratio together. This will be the denominator for each of the fractions and also represents the whole set. Then, each part of the ratio creates a fraction, with the numerator being the first part of the ratio and the denominator being the sum that was just found.

On Tuesday, a local hamburger shop sold a combined total of 402 hamburgers and cheeseburgers.
The number of cheeseburgers sold was two times the
number of hamburgers sold.
How many hamburgers were sold on Tuesday?
I hamburgers
Answer:
134
Step-by-step explanation:
2x +x =402
3x=402
x=134
2x=268
In this case x = hamburgers and 2x = cheeseburgers. And sense x = 134 that is your answer.
A hot air balloon is released at ground level, and it rises into the air at a constant rate. After 5 seconds the height of the balloon is 20 feet. The balloon continues to rise at the same rate.
Which table shows the relationship between the time in seconds, x , and the height of the balloon in feet, y?
Answer: D
Step-by-step explanation:
If after 5 seconds the height was 20 feet then in 10 seconds it will be 40 feet and in 20 seconds it will be 80 seconds.
To get from 5 to 10 you multiply by 2
To get from 20 to 40 you multiply by 2.
Since you have a constant change then it works for D only.
The linear equation that represents the height of the balloon at a time will be y = 4x. Then the correct option is D.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
A hot air balloon is launched from the ground and climbs into the air at a consistent velocity. The balloon's elevation is 20 feet after 5 seconds. The balloon keeps rising at the same rate.
The height per second is given as,
m = 20 / 5
m = 4 ft/sec
Then the equation is given as,
y = 4x
At x = 10 sec, then the value of y will be
y = 4 (10)
y = 40 ft
At x = 20 sec, then the value of y will be
y = 4 (20)
y = 80ft
The linear equation that represents the height of the balloon at a time will be y = 4x. Then the correct option is D.

A new uniform cost 49.99 if its on sale for 15% off what is the cost before tax
Answer:
$42.49
Step-by-step explanation:
This means the cost of the item to you is $42.49. You will pay $42.49 for a item with original price of $49.99 when discounted 15%. In this example, if you buy an item at $49.99 with 15% discount, you will pay 49.99 - 7.4985 = 42.49 dollars.
Answer:
42.49
Step-by-step explanation:
Discount = 15% of 49.99
= 0.15 * 49.99
= 7.4985
Cost after discount = 49. 99 - 7.4985
= 42.4915
= 42.49
An angle measures 86° less than the measure of its complementary angle. What is the measure of each angle?
[tex]x + (x - 86) = 90[/tex]
[tex]2x - 86 = 90[/tex]
Both sides plus 86
[tex]2x = 90 + 86[/tex]
[tex]2x = 176[/tex]
Divided both sides by 2
[tex]x = \frac{176}{2} \\ [/tex]
[tex]x = 88[/tex]
So the angles are :
[tex]88 \: \: \: \: \: and \: \: \: \: 2[/tex]
The measure of the two complementary angles are 88° and 2°.
What is a complementary angle?"When the sum of two angles is 90°, then the angles are known as complementary angles."
Let, the complementary angle of the mentioned angle is x.
Therefore, the angle is = (x - 86°)
Now, x + (x - 86°) = 90°
⇒ 2x - 86° = 90°
⇒ 2x = 176°
⇒ x = 88°
Therefore, the measured angle is 88°.
It's complementary angle is = (90° - 88°) = 2°.

Find the length of YZ
Answer:
[tex]YZ = 19cm[/tex]
Step-by-step explanation:
To figure out what line YZ equals, we must first find x. And to do this, let's set up an equation.
Firstly, we know that XY is 8cm, and XZ is 4x+3. So, we know that XY + YZ will equal XZ. Let's set that up:
[tex]8 + 2x+7=4x+3[/tex]
Combine like terms.
[tex]2x+15=4x+3[/tex]
Subtract 2x from both sides.
[tex]15=2x+3[/tex]
Subtract 3 from both sides.
[tex]12=2x[/tex]
Divide both sides by 2.
[tex]6=x[/tex]
Now, we just need to plug 6 into the equation of YZ.
[tex]2(6)+7[/tex]
[tex]12+7[/tex]
[tex]YZ = 19[/tex]

Answer:
Alright, so we got k + 9k = 8k - 6.
This means that 10k = 8k - 6.
As a result, we have 2k = -6, and k = - 6/2 = -3
So, k = -3 :)
