Suppose you got these results from a survey that was taken to determine the percentage of people in a nearby city who visited a food pantry last month. (2 points)
People who visited the food pantry last month
(%) x
(#) 100
Total amount of people
in the city
(%) 150
(#) 1,000
Calculate the percentage of people who visited the food pantry last month. Be sure to show your work.
1,000 is the number of people in the city 150 is the number of people who visited the food pantry last month. what % is 150 out of 1,000. Pleas show all of your work.
Answer:
15%
Step-by-step explanation:
percentage= number of people who visited the the pantry/ the total number of people in the city *100
percentage = 150/1000 * 100
percentage= 15%
PLEASE HELP SOON! ALSO INCLUDE A SMALL EXPLANATION as well as the answer ! I am rewarding 100points if you answer quickly
Answer:
the answer is B
f(x)=-2x+3
Step-by-step explanation:
to get the -2x I did --->
pick two points I used (0,3) and (1,1) and used the equation [tex]\frac{y2-y1}{x2-x1}[/tex]
where y2 would be 1 and y1 would be 3
and where x2 would be 1 and x1 would be 0
so you would put the numbers in the equation which would look like[tex]\frac{1-3}{1-0}=\frac{-2}{1}[/tex] and equal -2 which would be -2x in the answer
And the +3 is the y-intercept

An office manager has $11,000 to spend on new equipment. He planned to purchase 400 chairs for $72 each. He completed the calculations and concluded that there would be plenty of money left to buy additional equipment. Answer problems 4–6. LOADING... Click the icon to view the calculations. 4. What does the office manager do to support his thinking? Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. He does a calculation to find the cost of 400 chairs and compares the amount to $ nothing. (Type a whole number.) B. He does a calculation to find the cost of the additional equipment. C. He does a calculation to find the cost of 72 chairs. D. He does a calculation to find the difference between the cost of 400 chairs and the cost of the additional equipment and compares the amount to $ nothing. (Type a whole number.)
Answer:
A. He does a calculation to find the cost of 400 chairs and compares the amount to $11,000Step-by-step explanation:
Step one:
given data
total money =$11,000
number of chairs to be purchased= 400
cost per chair=$72
Step two:
the cost of 400 chairs will be
400*72= $28,800
there will be a deficit of
=28,800-11,000
=$17,800.
This shows that the office manager does not have enough funds for the purchase.
Hence to support his thinking,
A. He does a calculation to find the cost of 400 chairs and compares the amount to the amount he has.
The populations P (in thousands) of a certain city from 2000 through 2007 can be modeled by P = 1674.7e^kt, where t represents the year, with t = 0 corresponding to 2000. In 2006, the population of the city was about 1,920,000. Find the Value of K
Answer:
k = 0.02278
Step-by-step explanation:
Given that:
The population P = 1674.7e^kt
where;
t represents the year,
if year 2000 represents t = 0
Then, the year 2007 represents = 7; &
year 2006 represents = 6
In 2006, population recorded in the city was about 1,920 thousand
Therefore;
[tex]1920 = 1674.7e^{(k\times 6)[/tex]
Taking the logarithm of both sides, we get:
[tex]\mathtt{ In}(1920) = \mathtt{ In} ( 1674.7)+ 6k[/tex]
7.560080465= 7.423389324 + 6k
7.560080465 - 7.423389324 = 6k
0.136691141 = 6k
k = 0.136691141/6
k ≅ 0.02278

(3,17) is the ordered pair a solution ? Please show work
Answer:
yes
Step-by-step explanation:
y = 3(3) + 8
y = 9 + 8
y = 17
Answer:
Yes, (3, 17) is a solution.
Step-by-step explanation:
In an ordered pair the first variable is x, and the second is y (x, y), so we can take the x and y of the given point and put it into our equation.
y=3x+8
we replace y with our given y (17)
and our x with our given x (3)
17=3(3)+8
now solve
17=9+8
17=17
Both sides are equal so yes, (3, 17) is a solution.

3(m + 4) = 36
What is m
Answer:
m = 8
Step-by-step explanation:
Step 1: Write the equation neatly. {3 (m + 4) = 36}
Step 2: Distribute 3 to m and 4. {3 x m = 3m} {3 x 4 = 12}
Step 3: Write the new equation. {3m + 12 = 36}
Step 4: Subtract 12 from both sides. {12 - 12 = 0} {36 - 12 = 24}
Step 5: Write the new equation. {3m = 24}
Step 6: Divide 3 from both sides. {3m / 3 = m} {24 / 3 = 8}
Step 7: Write the new equation and you get your answer. {m = 8}

4x = 84
Divide by 4 from both sides!
x = 21 degrees
Answer:
x=21°
Step-by-step explanation:

Ms Tyler has a rectangular patio that she would like to decorate with string lights as shown in the diagram. If she plans to string the lights around the perimeter and across both diagonals how many feet of lights will she need? (READ CAREFULLY)
A: 47 feet
B: 60 feet
C: 80 feet
D: 13 feet
Answer:
the answer is b
Step-by-step explanation:
the answer would be b because you add 12+12 then 5+5 and if you add those together it would be 34 then you would add the diagonal lines together which would be 20 so then you would add 34 plus 26 and then you would get 60 which is b

This is the true statement ΔADB≅ΔBDC
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
In Δ ADB,
∠D = 90°
∠B = 90°/2 = 45°
∠A = 180° - 90° - 45° = 45°
So ΔADB is 90-45-45 triangle.
In ΔBDC,
∠ ? = 90° This is supplementary to Angle D.
∠ B = 90°/2 = 45°
∠ C = 180° - 90° - 45° = 45°
So, ΔBDC is also a 90-45-45 triangle.
Hence, ΔADB≅ΔBDC
