If 3 times a certain number is increased by 4 the result is 28. What is the number?
If x is "the number," which of the following equations could be used to solve for the number?
3x + 4 = 28
3 x= 4 + 28
3( x + 4) = 28
if f(x) = x^2, and
g(x) = x-1, then
g(f(x))=x^__+__
Answer:
(x^2) + (-1)
Step-by-step explanation:
the equation f(x) BECOMES x in the g(x)
x-1
(x^2) -1
Answer:
g(f(x)) = x^2 + (-1)
Step-by-step explanation:
f(x) = x^2
g(x) = x - 1
Therefore, for g(f(x)), we need to substitute the value of x in f(x) in g(x).
Therefore,
g(x) = (x^2) - 1
= (x^2) + (-1)

Translate the following into a verbal expression:
X2 - 5
are all composite numbers even
Answer:
No.
Step-by-step explanation:
A composite number has factors in addition to one and itself. The numbers 0 and 1 are neither prime nor composite. All even numbers are divisible by two and so all even numbers greater than two are composite numbers. All numbers that end in five are divisible by five. Therefore all numbers that end with five and are greater than five are composite numbers.

What type of number is pi?
Answer:
Pi is an irrational number
Step-by-step explanation:
Pi is an irrational number because it cannot be written down as a simple fraction.
Answer:
We know that pi is a number that never ends. Its decimals can be written out forever endlessly. Therefore, it must be an irrational number.
Step-by-step explanation:
First, let us go over the different types of numbers:
Natural Numbers - 1, 2, 3, ...
Whole Numbers - All natural numbers including 0
Integers - All whole numbers, both positive and negative
Rational Numbers - All numbers, both positive and negative that can be represented as a fraction. In other words, they have a terminating decimal point
Irrational Numbers - Numbers that cannot be written as a fraction. Numbers who have an infinite number of decimal points
Real Numbers - Includes everything else listed.

(0.0) r=5
(0,0) r=25
(3.2) r=25
Answer:
x=√−y2+25 or x=−√−y2+25
Step-by-step explanation:
x2+y2=25
Step 1: Add -y^2 to both sides.
x2+y2+−y2=25+−y2x2=−y2+25Step 2: Take square root.
x=√−y2+25 or x=−√−y2+25Answer:
x=√−y2+25 or x=−√−y2+25
For a certain online store, the distribution of number of purchases per hour is approximately normal with mean 1,200 purchases and standard deviation 200 purchases. For what proportion of hours will the number of purchases at the online store exceed 1,400 ?
Answer: 0.1587
Step-by-step explanation:
Given : The distribution of number of purchases per hour is approximately normal with mean 1,200 purchases and standard deviation 200 purchases.
i.e. [tex]\mu=1200,\ \ \sigma=200[/tex]
Let X denotes the number of purchases per hour.
Then ,
[tex]P(X>1400)=P(\dfrac{X-\mu}{\sigma}>\dfrac{1400-1200}{200})\\\\=P(Z>1)\ \ \[Z=\dfrac{X-\mu}{\sigma}]\\\\=1-P(Z<1)\ \ \ [P(Z>z)=1-P(Z<z)]\\\\\ =1-0.8413\ \ [\text{By p-value table}]\\\\= 0.1587[/tex]
So, the proportion of hours will the number of purchases at the online store exceed 1,400 =0.1587
Please help! I don't know if my answer is correct.
Answer:
c/20 cups
Step-by-step explanation:
Number of students in the baking club = 10
If each student made 2 cakes
then total cakes prepared by the students = 10 × 2 = 20
If total amount of flour used to prepare 20 cakes = c cups
and amount of flour used to prepare one cake = n cups
Then amount of flour used to prepare 20 cakes = 20n
Therefore, total amount of flour c = 2n
or n = c/20
Amount of flour used for one cake = c/20 cups
Answer:
the answer is c/20 cups!

The Navy Pier Ferris Wheel in Chicago has a circumference that is 56% of the circumference of the first Ferris wheel built in 1893. The Circumfrence of the Navy Peir wheel is 439.6 ft. What is the radius of the first ferris wheel?
Hey there! I'm happy to help!
439.6 is 56% of the first Ferris wheel. The word is means equals, so we can set up the following equation. We will call the original wheel w.
439.6=0.56w
We divide both sides by 0.56
w=785
We divide by 3.14 to find the diameter.
785/3.14=250
Radius is half of the diameter.
250/2=125
The radius of the first Ferris wheel is 125 ft.
Have a wonderful day! :D
Step-by-step explanation:
439.6=0.56w
We divide both sides by 0.56
w=785
We divide by 3.14 to find the diameter.
785/3.14=250
Radius is half of the diameter.
250/2=125
The radius of the first Ferris wheel is 125
125ft.
answerers about Caca Andika from IndonesiaA helicopter flies between two islands that are 20 miles apart. The angle of elevation with one island is 15o and 35o with the second island. What is the mileage of the helicopter? Round your answer to the nearest tenth of a mile. (Law of Sines or Law of Cosines Problem)
Answer:
Step-by-step explanation:
From the figure attached,
A helicopter is flying at a height 'h' and angle of elevations from two islands C and B are 35° and 15° respectively.
Let the measure of BD = x miles
From ΔABD,
tan(15) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}=\frac{h}{x}[/tex]
h = x.tan(15) ---------(1)
From ΔACD,
tan(35) = [tex]\frac{h}{12-x}[/tex]
h = (12 - x).tan(35) ------(2)
By equating the values of h from equations (1) and (2),
x.tan(15) = (12 - x).tan(35)
[tex]\frac{x}{12-x}=\frac{\text{tan}35}{\text{tan}15}[/tex]
[tex]\frac{x}{12-x}=2.613[/tex]
x = 2.613(12 - x)
x + 2.613x = 31.386
3.613x = 31.386
x = 9.914 ≈ 9.9 miles
From equation (1),
h = x.tan(15)
= 9.9[tan(15)]
= 2.65 ≈ 2.7 miles
Therefore, helicopter is flying at the vertical height = 2.7 miles and horizontal distance of the helicopter from the island B = 9.9 miles.

2.7

What vertical line (V) and horizontal line (H) intersect at point C? Question 9 options: A) V: x = –2.5; H: y = 5.5 B) V: y = 5.5; H: x = –2.5 C) V: y = –2.5; H: x = 5.5 D) V: x = 5.5; H: y = –2.5
Answer:
its b
Step-by-step explanation:
The vertical line (V) and horizontal line (H) intersect at point C are V: x = 5.5; H: y = –2.5 option (D) is correct.
What is a straight line?
A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
From the graph,
The coordinate of point C is (5.5, -2.5)
The vertical line (V) and horizontal line (H) intersect at point C are:
x = 5.5 (Vertical line)
y = -2.5 (Horizontal line)
Thus, the vertical line (V) and horizontal line (H) intersect at point C are V: x = 5.5; H: y = –2.5 option (D) is correct.
