A population of 470 animals decreases at an annual rate of 12%.
a.f(x)=470(1.88)x
b.f(x)=470(0.12)x
c.f(x)=470(0.88)x
d.f(x)=470(1.12)x
Answer:
C. f(x) = 470(0.88)ˣStep-by-step explanation:
Initial number = 470Decrease rate = 12% ⇒ 100% - 12% = 88% ⇒ 0.88 timesRequired equation:
f(x) = 470(0.88)ˣCorrect choice is C

Answer:
m<ADC = 107
Step-by-step explanation:
You need to know three things to solve this problem.
1) Opposite angles of an inscribed quadrilateral are supplementary.
2) The measure of an inscribed angle is half the measure of its subtended arc.
3) The sum of the measures of all the arcs of a circle is 360 deg.
From 1) we get:
m<A + m<C = 180
72 + m<C = 180
m<C = 108
From 2) we get:
m<C = (1/2)m(arc)BAD
108 = (1/2)[m(arc)AB + m(arc)AD]
216 = m(arc)AB + 122
m(arc)AB = 94
From 3) we get:
m(arc)AB + m(arc)BC + m(arc)CD + m(arc)DA = 360
94 + 120 + m(arc)CD + 122 = 360
m(arc)CD = 24
From 2) we get:
m<ADC = (1/2)m(arc)ABC
m<ADC = (1/2)[m(arc)AB + m(arc)BC]
m<ADC = (1/2)[94 + 120]
m<ADC = 107
CAN SOMEONE PLEASE FIND THE VOLUME AND SURFACE AREA OF THIS FIGURE.
and round to the nearest hundredth
Answer:
Volume = 1659.84Surface area = 1205.36Step-by-step explanation:
Volume for triangular prism = 1/2 * b * l * h
we are given the length and the height but not the base.
since it is a right triangle we can use the Pythagorean theorem a^2 + b^2 = c^2
13.3^2 + b^2 = 20.5^2
176.89 + b^2 = 420.25
b^2 = 243.36
b = [tex]\sqrt{243.36}[/tex] = 15.6
1/2 (15.6)(13.3)(16) = 1659.84
Front: 15.6 x 13.3 = 207.48
Back: 15.6 x 13.3 = 207.48
Left: 15.6 x 16 = 249.6
Right: 13.3 x 16 = 212.8
Bottom: 20.5 x 16 = 328
207.48 + 207.48 + 249.6 + 212.8 + 328 = 1205.36

Find The Product of:
[tex] \sqrt[3]{2} \times \sqrt[6]{5} [/tex]
Answer:
Step-by-step explanation:
You can find the cube root of 2 and multiply it by the 6th root of 5.
cube root(2) = 2^(1/3) = 1.2599
6th root of (5) = 0.7418
Product = 1.2599 * 0.7418 = .9346

B. T=winning time in the man's 100 meter dash at the 2016 Olympics
C. P=number of points scored by Stephen curry in a game
D.H=The number of hats sold on Tuesday

Mr. Snyder begins traveling east on Interstate 90 from Spokane with a full tank of gasoline. His car has a 15-gallon gas tank and gets 30 miles per gallon during highway travel. Let m = the number of miles Mr. Snyder has driven Let g = the number of gallons of gas remaining in his tank Select in the letter of the equation that describes the relationship between the number of miles Mr. Snyder has traveled and the number of gallons remaining in his gas tank.
Answer:
[tex]g = 15 - \frac{1}{30}m[/tex]
Step-by-step explanation:
Given
[tex]Initial = 15[/tex]
[tex]mpg = 30[/tex] --- miles per gallon
Required
Determine an equation for this trip
First we have to get the number of gallons per mile from [tex]mpg = 30[/tex]
[tex]\frac{miles}{gallon}=30[/tex]
Inverse the equation
[tex]\frac{gallon}{miles}=\frac{1}{30}[/tex]
This represents the rate in gallons/mile
So, the equation is:
[tex]g= Initial - Rate * m[/tex]
[tex]g= 15 - \frac{1}{30} * m[/tex]
[tex]g= 15 - \frac{1}{30}m[/tex]
A student is standing next to a vertical flagpole. The top of the student's shadow
coincides with the top of the flagpole's shadow as shown.
not to scale
The student is 62 inches tall. The student estimates that the distance from the flagpole
to the point where the student is standing is between 21 and 22 feet. The student also
estimates that the length of the student's shadow is between 7 and 7 feet.
Based on the given information, what are the least and greatest possible heights, in
feet, of the flagpole? Explain how you arrived at your answers.
Answer:
The least possible height of the flagpole is 227.33 inches and the greatest possible height is 248 inches
Step-by-step explanation:
Given
See attachment for the system
Required
Determine the least and greatest heights of the flagpole
From the question, we have:
[tex]AB = 7\ to\ 7\frac{1}{2} ft[/tex]
[tex]BE =62in[/tex]
[tex]BC = 20\ to\ 21ft[/tex]
Convert AB and BC to feet (multiply by 12)
[tex]AB = 84in\ to\ 90in[/tex]
[tex]BC = 240in\ to\ 252in[/tex]
The height of the flagpole is represented as: CD
To calculate CD, we make use of the following equivalent ratios:
[tex]CD : AC = BE : AB[/tex]
Express as fraction
[tex]\frac{CD }{ AC } = \frac{BE }{ AB}[/tex]
Make CD the subject
[tex]CD = \frac{BE }{ AB} * AC[/tex]
From the attachment:
[tex]AC = AB + BC[/tex]
Where:
[tex]AB = 84in\ to\ 90in[/tex]
[tex]BC = 240in\ to\ 252in[/tex]
The possible values of AC are:
[tex]AC = 84 + 240 =324in[/tex]
[tex]AC = 84 + 252 =336in[/tex]
[tex]BC = 90 + 240 = 330in[/tex]
[tex]AC = 90 + 252 =342in[/tex]
So:
[tex]CD = \frac{BE }{ AB} * AC[/tex]
[tex]BE =62in[/tex]
When AC = 324 ; AB = 84
[tex]CD = \frac{62}{84} * 324[/tex]
[tex]CD = \frac{62* 324}{84}[/tex]
[tex]CD = \frac{20088}{84}[/tex]
[tex]CD = 239.14in[/tex]
When AC = 336 ; AB = 84
[tex]CD = \frac{62}{84} * 336[/tex]
[tex]CD = \frac{62* 336}{84}[/tex]
[tex]CD = \frac{20832}{84}[/tex]
[tex]CD = 248in[/tex]
When AC = 330 ; AB = 90
[tex]CD = \frac{62}{90} * 330[/tex]
[tex]CD = \frac{62 * 330}{90}[/tex]
[tex]CD = \frac{20460}{90}[/tex]
[tex]CD = 227.33in[/tex]
When AC = 342 ; AB = 90
[tex]CD = \frac{62}{90} * 342[/tex]
[tex]CD = \frac{62* 342}{90}[/tex]
[tex]CD = \frac{21204}{90}[/tex]
[tex]CD = 235.6in[/tex]
So, we have:
[tex]CD = 239.14in[/tex]
[tex]CD = 248in[/tex]
[tex]CD = 227.33in[/tex]
[tex]CD = 235.6in[/tex]
The least possible height of the flagpole is 227.33 inches and the greatest possible height is 248 inches
The given range of the length of the shadow and distance of the student
from the tree of between 7 and [tex]7\frac{1}{2}[/tex] feet and 21 and 22 feet gives;
The greatest possible height of the flagpole in feet ≈ 21.8 feet
The least possible height of the flagpole in feet = 19.3 feet
How can the height of the tree be calculated?Height of the student = 62 inches = [tex]5\frac{1}{6}[/tex] feet
Distance of the flagpole to the student = 21 to 22 feet = 252 to 264 inches
Length of the student's shadow = Between 7 and [tex]\mathbf{7\frac{1}{2}}[/tex] feet = Between 84 and 90 inches
Required:
The least and greatest height of the flagpole.
Solution;
By using similar triangles formed by the student and the flagpole, we
have;
[tex]\dfrac{Height \ of \ the \ student}{Length\ of \ the \ student's \ shadow} = \mathbf{\dfrac{Height \ of \ the \ flagpole}{Length\ of \ the \ flagpole's \ shadow}}[/tex]
Which gives;
[tex]\dfrac{62}{84 \ or \ 90} =\mathbf{ \dfrac{h}{252+(84 \ or \ 90) \ or \ 264 + (84 \ or \ 90)}}[/tex]
Based on the method of cross multiplication, h will be the greatest
possible value, when we have, the largest possible value for the
denominator on the right hand side and the least possible value for the
denominator on the left hand side of the equation, and vice versa.
Which gives;
[tex]\dfrac{62}{90} = \mathbf{\dfrac{h_{min}}{252 + 84}}[/tex]
[tex]h_{min} \ in \ feet = \mathbf{\dfrac{\dfrac{62}{90} \times (252 + 84)}{12}} \approx 19.3[/tex]
The least possible height of the flagpole in feet, [tex]h_{min}[/tex] ≈ 19.3 feet
Similarly. we have;
[tex]\dfrac{62}{84} = \mathbf{\dfrac{h_{max}}{264 + 90}}[/tex]
Which gives;
[tex]h_{max} = \dfrac{62}{84} \times (264 + 90) \approx 261.3[/tex]
[tex]h_{max} \ in \ feet \approx \dfrac{261.3}{12} \approx\mathbf{ 21.8}[/tex]
The greatest possible height of the flagpole in feet, [tex]h_{max}[/tex] ≈ 21.8 feet

In a school, 30% of the students arrived by private car, 15 travel by taxi and the remainder walk to school. If the school has a population of 230, how many more students walk to school than arrives by car?
Answer:
57.5 students
Step-by-step explanation:
Given that
The 30% students would be arrived by private car
So 15% would be travelled by taxi
And, the remaining i.e. 55% would be walk to school
Since the population of the school is 230
So by car, the students would be
= 230 × 0.30
= 69
By walk, the students would be
= 230 × 0.55
= 126.50
Now the more students would be
= 126.50 - 69
= 57.5 students

Three-fifths of the students in a room are girls. One-third of the girls have blond hair. One-half of the boys have brown hair. What fraction of all the students are girls with blond hair?
Answer:
1/5
*I'm sorry if I got it wrong, but if not I hope this helps!*
Step-by-step explanation:
since 3/5 of the students are girls, and 1/3 of the girls have blonde hair, to find what fraction of all the girls have blond hair, we would multiply 3/5(1/3)
3/5(1/3)=3/15=1/5
therefore, 1/5 of all the students are girls with blond hair
