Step-by-step explanation:
g o o g l e
for the percent times the decimal by 100 and for the decimal just divide the fraction by it self so 15 divided by 16
Answer:
0.9375
93/75%
Step-by-step explanation:
Perform the division:
15 / 16 = 0.9375
and then find the percent form by multiplying this result by 100:
0.9375 * 100 = 93.75%
A right triangle has one angle that measures 60 degrees. What is the measure of the other a cute angle?
Answer:
30 degrees.
A right triangle will have one angle that is 90 degrees. If another angle is 60, you can set up your equation like this to find the third angle - and remember that interior triangle angles equal 180 -
90 + 60 + x = 180
150 + x = 180
-150 -150
x = 30

If (x + 8) is a factor of f(x), which of the following must be true?
Both x = -8 and x = 8 are roots of f(x).
Neither x = -8 nor x = 8 is a root of f(x).
fl-8)=0
f(8) = 0
Answer:
[tex]x = -8[/tex] is a root.
[tex]f(-8) = 0[/tex] is correct.
Step-by-step explanation:
As
[tex](x + 8)[/tex] is a factor of [tex]f(x)[/tex]
then it must be
[tex]x = -8[/tex] is a root.
Therefore,
[tex]f(-8) = 0[/tex] is correct.

Tyler says, "9 x 7 is greater than 7 X 9
because the greater number is first." Explain Tyler's error.
Answer:
9x7 and 7x9 is the same equation and will get the same product with is 63.
The commutative Property of Multiplication states that; a × b = b × a therefore,9 × 7 = 7 × 9.
What is multiplication?Multiplication is the general procedure in mathematics multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.
Commutative property → for any two numbers a and b ⇒ a × b = b × a
For example , 2 × 3 = 3 × 2
The order of multiplication doesn't matter in multiplication.
Given that,
9 × 7 = 63 and 7 × 9 = 63 therefore,9 × 7 = 7 × 9.
In subtraction order matters, for example, 4 - 2 is greater than 2 - 4 thus Tyler's error is that he misunderstood multiplication with subtraction.
Hence "The commutative Property of Multiplication states that; a × b = b × a, therefore,9 × 7 = 7 × 9".

Suppose commute times in a large city are normally distributed and that 63.70% of commuters in this city take more than 22 minutes to commute one-way. If the standard deviation of such commutes is 6.3 minutes, what is the mean commute?
Answer:
The mean is 24.205
Step-by-step explanation:
Firstly, we need to get the z-score
From the question, the probability we have is the probability that commuters take more than 22 minutes to commute one-way
So the probability we had was;
P( x > 22)
So we need the z-score corresponding to 63.70% or simply 0.637
We can use the standard normal distribution table to get this
Mathematically, from the standard normal distribution table this is -0.35
z-score = (x- mean)/SD
-0.35 = (22-mean)/6.3
22-mean = -2.205
mean = 22 + 2.205 = 24.205

Top Tech adds 55% to the wholesale cost it pays for its inventory. Top Tech bought a wireless mouse for $24. What will be the retail price of the wireless mouse? Round to the nearest penny.
9514 1404 393
Answer:
$37.20
Step-by-step explanation:
Adding 55% to the cost means the cost is multiplied by 1+55% = 1.55.
$24 × 1.55 = $37.20
The retail price will be marked as $37.20.
describe how do you know if two lines are parallel if all you knew were the equations of the two lines
Answer:
Step-by-step explanation:
Put what you are given in the form of
y = mx + b
If both equations have the same m, the lines are parallel. For example
y = 4x + 10
y = 4x + 20
These two lines are parallel.
However
y = 8x + 40
y = 4x + 10 are not parallel even though it looks like m could be made the same by taking out 4 in each. Check them out on the graph below.

The Bureau of Alcohol, Tobacco, and Firearms (BATF) has been concerned about lead levels in California wines. In a previous testing of wine specimens, lead levels ranging from 51 to 710 parts per billion were recorded. How many wine specimens should be tested if the BATF wishes to estimate the true mean lead level for California wines to within 10 parts per billion with 95% confidence
Answer:
The sample size is [tex]n = 1043 [/tex]
Step-by-step explanation:
From the question we are told that
The lower bound of the range is a = 51
The upper bound of the range is b = 710
The margin of error is [tex]E = 10[/tex]
Generally the standard deviation is mathematically represented as
[tex]\sigma = \frac{b- a}{4}[/tex]
=> [tex]\sigma = \frac{710 - 51 }{4}[/tex]
=> [tex]\sigma = 164.75[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2[/tex]
=> [tex]n = [ 1.96 * 164.75 }{10} ] ^2[/tex]
=> [tex]n = 1043 [/tex]

Answer:
y + 2 = [tex]-\frac{3}{2}[/tex] (x - 3)
Step-by-step explanation:
y - [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex])
If AB ⊥ CD , then [tex]m_{AB}[/tex] × [tex]m_{CD}[/tex] = - 1

The Latin root word that means "stranger/enemy" is
Answer:Latin hostis
Step-by-step explanation:
gostĭ is “guest,” whereas that of Latin hostis is “enemy.” To explain the connection between “guest” and “enemy” it is usually supposed that both derived their meaning from “stranger,” a sense which is still attested in Latin. The notion “favorable stranger” developed to “guest”; that of “hostile stranger” to “enemy.”
Answer:
Latin hostis

A recipe uses 4 cups of milk to make 12 servings. If the same amount of milk is used for each serving, how many servings can be made from three gallons? Before you try that problem, answer the question below. How many cups will you need to find the number of servings for?
Answer:
144 servings
Step-by-step explanation:
Step 1
We convert 3 gallons to cups
1 gallon = 16 cups
3 gallons = x cups
x = 3 × 16 cups
x = 48 cups
Step 2
If
4 cups of milk = 12 servings.
48 cups of milk = x servings
Cross Multiply
4 × x = 48 × 12
x = 48 × 12/4
x = 144 servings
Therefore, 3 gallons of milk(48 cups) = 144 servings

Jack rides his bicycle 4 miles in 30 minutes. If he maintains this rate, how far will he ride in 3 hours?
A
12 miles
B
24 miles
С
B
34 miles
2
D
240 miles
Answer: :/
Step-by-step explanation:yo que se
Answer:
A) 24 miles
Step-by-step explanation:
So jack rides 4 miles in half an hour.
a full hour = 8 miles.
so we just multiply the amount he rides in 1 hour 3 times.
8*3=24
so 3 hours of maintaining this speed would equal 24 miles of ride time.
