Step-by-step explanation:
630
Answer:
789 to nearest whole number.
Step-by-step explanation:
In 4 years its increased from 220 to 350.
350 = 220(e)^4k where k is some constant.
e^4k = 350/220
4k = ln (350/220) = 0.4643
k = 0.1161
The equation of growth is therefore
P = 220e^0.1161t)
So in 2011 ( t = 11 years) the
Population = 220 * e^(11*0.1161)
= 789.
help please I would appreciate it thank u
Answer:
radius = 7.5 cm
Step-by-step explanation:
Since M is the midpoint of the chord AB then OM is perpendicular to AB
Using Pythagoras' identity in right triangle OMB with hypotenuse OB, the radius of the circle, then
OB² = OM² + MB² = 4.5² + 6² = 20.25 + 36 = 56.25 ( take square root of both sides )
OB = radius = [tex]\sqrt{56.25}[/tex] = 7.5
Jameson puts $4,000 in graduation money in an account for 10 years. The interest rate is 4.2%. If he withdraws all of the money after 10 years, how much
does he take out?
Answer:
2,320
Step-by-step explanation:
4.2% gets taken every year and there is 10 year,so 4.2% s uqual to 0.042,so just mutiply 4000 by 0.042 which is 168,then times 168 by 10 which brings you to 1680 and 4000 subtracyed by 1680,which equals 2,320

70% of the magic tricks that Jade knows are card tricks. If she knows 14 card tricks, how many magic tricks does Jade know in all?
Answer:
20
Step-by-step explanation:
Given data
Let the number of magic tricks be x
we are told that she knows 70% of card trick which is 14 card tricks
hence we have
70/100*x= 14
0.7x= 14
x= 14/0.7
x=20
Hence the number of magic tricks she knows is 20
Please help me with this math question.
Answer:
275 m^3
Step-by-step explanation:
The volume of a triangular pyramid is V=(1/3)Ah, where A is the area of the triangular base and h is the height.
First, let's find A, the area of the base. The area of a triangle is bh/2, where b is the base and h is the height.
In this question, 5 is the base and 15 is the height, so A=5*15/2=75/2.
Now we know A is 75/2, so let's go back to the formula for the volume of a pyramid. We are given h is 22, so
V=(1/3)(75/2)*22=275

In a circle, an angle measuring 2π radians intercepts an arc of length 14π. Find the radius of the circle in simplest form.
Answer:
7 radians
Step-by-step explanation:
In a circle, an angle measuring 2π radians intercepts an arc of length 14π. Find the radius of the circle in simplest form.
Since our Angle in in radians
The formula for Arc length = S = rθ
S = 14π
θ = central angle = 2π radians
Hence
r = S/θ
r = 14π/2π radians
r = 7 radians
Radius = 7 radians

Find the area of the trapezoid
A. 168 in^2
B. 94.5 ft^2
C. 72 ft^2
D. 84 ft^2
Answer:
D. 84 ft^2
Step-by-step explanation:
Formula for area of a trapezoid:
[tex]A=\frac{a+b}{2} h[/tex]
where a and b = bases and h = height
The trapezoid shown has the following dimensions
base 1 = 9ft
base 2 = 12ft
height = 8ft
Using the following information we plug in the values into the formula
[tex]A=\frac{9+12}{2} \\9+12=21\\\frac{21}{2} =10.5\\10.5*8=84[/tex]
Hence, the area of the trapezoid is 84ft² and your answer is D

7. A rectangular prism measures 7 1/2 cm by 12 cm by 15 1/2 cm. a. Calculate the number of cubes with edge length cm that fit in this prism. b. What is the volume of the prism in cm3? Show your reasoning. If you are stuck, think about how many cubes with -cm edge lengths fit into .
Answer:
a.The number of cubes with edge length 1/2 cm that fit in this prism= 2520
b. Volume of the prism= 315 cm³
Step-by-step explanation:
Volume of the rectangular prism = length *width * height
= 7 1/2 * 12 * 15 1/2
= 7 * 6* 15 1/2
= 7*3*15
= 315 cm³
Volume of the cube = length *width * height
= 1/2 *1/2 *1/2
= 1/8 cm³
Now number of cubes that would fit in the rectangular prism is given by
= Volume of the prism/ Volume of the cubes
= 315/1/8
= 2520
The number of cubes with edge length cm that fit in this prism= 2520

Solve the inequality for t.
11 ≤ t + 4
Simplify your answer as much as possible.
Answer:
t≥7
Step-by-step explanation:
11≤t+4
4 moves to the other side hence its sign changes
11-4≤t
7≤t
they change sides
t≥7
the sign was facing t so this does not change
Answer:
Step-by-step explanation:
Here are some steps to help you
Step 1
11 ≤ t + 4 We are gonna simplify
Step 2
11 ≤ t + 4 simplify
t+4≥11
Step 3
t+4≥11 Subtract 4 from the sides
t≥7
So therefore, your answer will be t≥7

Step-by-step explanation:
a line with a slope of 1 passes through the point (5,10). what is the equation in this slope-intercept form?
Answer:
y=x+5
Step-by-step explanation:
So first you need to plug everything into the point-slope formula which is
y-y1=m(x-x1)
m being the slope and y1 and x1 being the point (5,10)
So once you plug it in it should look like this: y-10=1(x-5)
Now you solve it
First you need to distribute 1 in 1(x-5) which is (x-5)
Now you have y-10=x-5
Then you add 10 to both sides which is y=x+5
Your answer is y=x+5
what is the probability that you will fail a test (pass or fail), draw a red ace, and then roll a 6?
Answer:
0.7890176%
Step-by-step explanation:
First, there is a 64% chance of failing a test.
Then there are 54 cards in a deck. There are two colors, red and black. There are two red aces and two black aces. You have a 50% chance that the card is red. Then there are 27 cards of each color. Since there are 2 aces in those 27, there is a 2/27 or ~7.4%.
Lastly there are 6 sides on a die. Each side has the same chance of landing. So this gets you 16.66%
Now we need to multiply each chance of something happening by one another
64% × 7.4% = 0.04736%
4.736% × 16.66% = 0.7890176%
So there is a 0.7890176% of all of these happening
The probability that you will fail a test, draw a red ace, and then roll a 6 is 0.7890176%
We have given that,
First, there is a 64% chance of failing a test.
We have to determine the probability
What is the probability?
Probability is an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.
Then there are 54 cards in a deck. There are two colors, red and black. There are two red aces and two black aces.
You have a 50% chance that the card is red. Then there are 27 cards of each color. Since there are 2 aces in those 27, there is a 2/27 or ~7.4%.
Lastly there are 6 sides on a die. Each side has the same chance of landing. So this gets you 16.66%
Now we need to multiply each chance of something happening by one another
64% × 7.4% = 0.04736%
4.736% × 16.66% = 0.7890176%
So there is a 0.7890176% of all of these happening
Therefore the probability that you will fail a test, draw a red ace, and then roll a 6 is 0.7890176%.

Which equation shows the quadratic formula used correctly to solve 7x^2 = 9 + x for x?
Answer:
Step-by-step explanation:
We must rewrite 7x^2 = 9 + x in standard form first: 7x^2 - x - 9 = 0.
The coefficients are 7, -1 and -9, and so the discriminant b^2 - 4ac is
(1)^2 - 4(7)(-9) = 253.
