Given:
Mark has only used 8.5% of a 34-oz bottle of shampoo.
To find:
How many ounces has he used?
Solution:
According to the question,
Shampoo used by Mark = 8.5% of a 34-oz
[tex]=\dfrac{8.5}{100}\times 34\text{-oz}[/tex]
[tex]=0.085\times 34\text{-oz}[/tex]
[tex]=2.89\text{-oz}[/tex]
Therefore, he used 2.89-oz of shampoo.

Sin(x+y) sin(x-y)=sin²x-sin²y
Answer:
Step-by-step explanation:
sin(x+y) = sin(x)cos(y) + sin(y)cos(x)
sin(x-y) = sin(x)cos(y) - sin(y)cos(x)
Sin(x+y)sin(x-y) = (sin(x)cos(y) + sin(y)cos(x))(sin(x)cos(y) - sin(y)cos(x))
= sin^2(x)cos^2(y) - sin^2(y)cos^2(x)
= sin^2(x)(1-sin^2(y)) - sin^2(y)(1-sin^2(x))
= sin^2(x) - sin^2(x)sin^2(y) - sin^2(y) + sin^2(x)sin^2(y)
= sin^2(x) - sin^2(y)
So L.H.S=R.H.S

A person receives a paycheck of d dollars. The person spends 18% of the
paycheck on rent, 15% of the paycheck on insurance, and 22% of the paycheck
on food and puts the remainder of the paycheck into savings.
If the amount the person puts into savings can be
represented by the
expression d - 0.18d - 0.15d - 0.22d, which expression also represents the
amount the person puts into savings?
O 0.45d
O 0.550
O 1.450
O 1.550
Answer:
0.45d
Step-by-step explanation:
Given that :
Amount of paycheck = d
Amount spent on rent = 18%
Amount spent on insurance = 15%
Amount spent on food = 22%
Amount put into savings = d - 0.18d - 0.15d - 0.22d
Amount put into savings = d - ( 0.18d + 0.15d + 0.22d)
d - 0.55d
Amount put into savings = 0.45d
If Lily got 18 questions right on a 20 questions
test, what percentage of the questions did she
get wrong?
Answer:
She got 10% of the questions wrong !
Step-by-step explanation:
To solve this problem I used cross multiplication
[tex]\frac{x}{100}= \frac{18}{20}[/tex]
18 x 100 =1800
1800 / 20 = 90
Since they are asking what she got wrong, not what she got right, you just need to subtract.
100% - 90% = 10%
hope this helped !
Answer:
10%
Step-by-step explanation:
18/20 Questions = 0.9 or 90% she got right
2/20 Questions = 0.1 or 10% she got wrong

Two sales representatives leave from the same office. One travels 20 miles due north and the other travels 5 miles due west. How far apart are the sales representatives? Estimate the distance to the nearest tenth. 22.6 mi 16.4 mi 20.6 mi 11.8 mi
Answer:
d = 20.6 miles
Step-by-step explanation:
Given that,
Two sales representatives leave from the same office. One travels 20 miles due north and the other travels 5 miles due west.
It is required to find the distance between two representatives. It it is d. It can be calculated as the resultant if two values as follows :
[tex]d=\sqrt{20^2+5^2} \\\\=20.61\ mi[/tex]
So, the sales representative are 20.6 miles apart. Hence, the correct option is (c).
After eating dinner at a restaurant, Alex's bill before tax is $78.00. The sales tax rate is 8%. Alex decides to leave a 20% tip for the waiter based on the pre-tax am
Answer:
$99.84Step-by-step explanation:
Step one:
given data
we are told that before tax the bill is pretax= $78
the tax is 8%
and he left 20% of the pretax for the attendant.
Step two:
let us find the amount he paid for eating with tax
=8/100*78
=0.08*78
=$6.24
with tax the meal cost is
= 78+6.24
=$84.24
let us solve for the tip he left (note: it is 20% of the pretax)
=20/100*78
=0.2*100
=$15.6
the tip is $15.6
Step three:
the total amount he paid after eating plus tax and tip is
78+6.24+15.6
=$99.84
Answer:
99.84

In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised, to produce that number x.
Joseph is making kebabs. He wants each kebab to have 3 pieces of meat and 4
pieces of vegetables.
Which of the following could Joseph use to make kebabs without any leftovers?
Answer:
Option D.
Step-by-step explanation:
From your comment, you said D was 30 pieces of meat and 40 pieces of vegetables. The starting ratio is 3:4. A true proportion is 3:4::30:40. 3 and 4 are both multiplied by 10 to get 30 and 40 therefore there would be no leftovers.

find the range value of x which satistfy inequality (x + 2)² > 2x + 7
Answer:
the range value of x which satisfy inequality [tex](x + 2)^2 > 2x + 7[/tex] is [tex]\mathbf{x>1 \ or \ x<-3}[/tex]
Step-by-step explanation:
We need to find the range value of x which satisfy inequality [tex](x + 2)^2 > 2x + 7[/tex]
Solving:
[tex](x + 2)^2 > 2x + 7[/tex]
Using formula: [tex](a+b)^2=a^2+2ab+b^2[/tex]
[tex]x^2+4x+4>2x+7\\x^2+4x+4-2x-7>0\\x^2+4x-2x+4-7>0\\x^2+2x-3>0[/tex]
Now factoring the term: [tex]x^2+2x-3>0[/tex]
Breaking the middle term: 2x= 3x-x
[tex]x^2+2x-3>0\\x^2+3x-x-3>0\\x(x+3)-1(x+3)>0\\(x-1)(x+3)>0\\x-1>0 \ or \ x+3>0\\x>1 \ or \ x<-3[/tex]
So, the range value of x which satisfy inequality [tex](x + 2)^2 > 2x + 7[/tex] is [tex]\mathbf{x>1 \ or \ x<-3}[/tex]

In 2020, a town was recorded as having a population of 10,000 and is predicted to grow at 5% every year. What will be the population in 2035, to the nearest whole number? *
Answer:
20789
Step-by-step explanation:
The equation of exponential growth is y=A(1+r)^t
A=10,000
r (rate)=0.05 (5% as a decimal)
t (time)=15 (2035-2020=15)
y=10,000(1+0.05)^15
y=20789.2817
you can't have part of a person, so y=20789
