shown in the table
Enter numbers in the empty boxes to correctly complete the table.
Building (feet) Model (inches)
Height
128
Length of Base
Width of Base
80
6.25
Answers
Answer:
height: 16 inch
length of base: 10 inch
width of base: 50 feet
Step-by-step explanation:
128*(1/8)=16 inch
80*(1/8)=10 inch
x*1/8=6.25
x=6.25*8=50 feet
The height and length of the model will be 16 in and 10 in respectively, and the width of the building will be 50 feet.
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
Given that, the scale factor of the building and a model of it is 1/8.
Height of the model = 128/8 = 16 in
Length of the model = 80/8 = 10 in
Width of the model = 6.25*8 = 50
Hence, The height and length of the model will be 16 in and 10 in respectively, and the width of the building will be 50 feet.

This is solved by plugging in each option one by one, and seeing which one results in a positive value for dy/dt.
dy/dt = (4 − 1) (1 − 2²) = -9
dy/dt = (7 − 1) (1 − 1²) = 0
dy/dt = (1 − 1) (1 − 2²) = 0
dy/dt = (-4 − 1) (1 − 0²) = -5
dy/dt = (3 − 1) (1 − 0²) = 2
Only the last option fits.

A sector of a circle of radius 80 mi has an area of 1600 mi2. Find the central angle (in radians) of the sector.
Answers
Answer:
The central angle of the sector is 0.5 radian
Step-by-step explanation:
given;
radius of the circle, r = 80 mi
area of the sector, A = 1600 mi²
Area of sector is given by;
A = ¹/₂r²θ
where;
θ is the central angle (in radians) of the sector
[tex]\theta = \frac{2A}{r^2}\\\\\theta = \frac{2*1600}{80^2}\\\\ \theta = 0.5 \ radian[/tex]
Therefore, the central angle of the sector is 0.5 radian
The central angle (in radians) of the sector is 28.66 degrees
The formula for calculating the area of a sector is expressed as:
[tex]A = \theta/360 \times \pi r^2[/tex]
Given the following parameters
radius r = 80mi
Area of sector A = 1600mi²
Substitute the given parameters into the formula
1600 = Ф/360 * (3.14)(80)²
1600 * 360 = 20,096Ф
Ф = 576000/20,096
Ф =28.66 degrees
Hence the central angle (in radians) of the sector is 28.66 degrees

Answer:
well, there is already $900 so 1800-900=900 now we need 4% of 900 which is $36 900 divided by 36 is 25
it will take 25 years
Step-by-step explanation:
plz mark brainliest i answered first
The number of years that will it take for the value of the account to reach $1,800 should be 25 years.
Calculation of the number of years:Since the deposited amount is $900
The rate of interest is 4%
The future value is $1,800
So here the balance amount should be
= $1,800 - $900
= $900
Now 4% of $900 = 36
So the number of year should be
= [tex]900\div 36[/tex]
= 25 years
hence, The number of years that will it take for the value of the account to reach $1,800 should be 25 years.

The different kinds of beads that Casey is
using to make purses come in packages of
3 and 9. What is the least number of each
kind of bead that Casey can buy to have an
equal number of each of the different kinds
of beads?
Answers
Answer:
Casey can buy 3 packages with 3 beads and one package with 9 beads to have the same number of beads of each kind.
Step-by-step explanation:
Given that:
The beads come in packages of 3 and 9.
To calculate the least number of beads that Casey can have, we will find the least common multiple of both packages.
Package of three = 3, 6, 9, 12, 15
Package of nine = 9, 18, 27, 36
The least common multiple of 3 and 9 is 9.
Hence,
Casey can buy 3 packages with 3 beads and one package with 9 beads to have the same number of beads of each kind.
An urn contains 17 white balls and 18 red balls. A sample of four balls is selected at random from the urn. What is the probability that the sample contains two white balls and two red ones?
a. 0.0286
b. 0.2286
c. 0.3974
d. 0.0944
e. 0.0442
f. None of the above.
Answers
Answer:
c. 0.3974
Step-by-step explanation:
Given;
number of white balls, W = 17
number of red balls, R = 18
Total number of balls, T = 35
The number of ways the event will occur is given by
= P(2 whites) and P(2 reds)
= P(2whites) x P(2 reds)
= 17C2 x 18C2
= 136 x 153
= 20,808
The total number of possible outcome
= 35C4
= 52,360
The probability = 20,808 / 52,360
= 0.3974
The correct option is "C"
Probability that the sample contains two white balls and two red ones is equal to 0.3974.
So, option c. is correct.
Permutations and combinationsProbability is a discipline of mathematics concerned with numerical explanations of the likelihood of an event occurring or the truth of a claim.
Number of white balls [tex]=\boldsymbol{17}[/tex]
Number of red balls [tex]=\boldsymbol{18}[/tex]
Total number of balls [tex]=\boldsymbol{35}[/tex]
Probability that the sample contains two white balls and two red ones
[tex]=\frac{\binom{17}{2}\binom{18}{2}}{\binom{35}{4}}[/tex]
[tex]=\frac{\frac{17!}{15!2!}\frac{18!}{16!2!}}{\binom{35!}{31!4!}}[/tex]
[tex]=\boldsymbol{0.3974}[/tex]
So, option c. is correct.
