Answer:
1000
Step-by-step explanation:
The population of the suburb after each decade d is given by the equation as follows :
[tex]P=4000\times 2^d[/tex]
We need to evaluate the expression for d = -2.
Put d = -2 in the above equation. So,
[tex]P=4000\times 2^{-2}\\\\=4000\times \dfrac{1}{2^2}\\\\=4000\times \dfrac{1}{4}\\\\=1000[/tex]
So, if d = -2, then the population of the suburb is equal to 1000.
Find the measurement of angle ABC
Answer:
x=97° a=97° b=97°
Step-by-step explanation:
83°+a=180° (by linear pair)
a=180°- 83°
a=97
and a=x°(by corresponding angle)
x= 97°
x=b(by vertical opposite angle)
b = 97°
In Kailah's class the ratio of girls to boys is 13 to 8. If there were 16 boys, how many girls will there be?
Answer:
I believe that the answer is 26
Step-by-step explanation:
The ratio of girls to boys is 13 to 8 so there are 13 girls for every 8 boys so if there are 16 boys (8X2) then there are 26 girls (13X2)
could someone help me? i'd appreciate it thank you
x = 70°, y = 30°, z = 20°
Step-by-step explanation:
Right triangle have a total internal angle of 180°.
x = 180° - 110°
= 70°
z = 180° - 90° - x
= 180° - 90° - 70°
= 20°
y = 180° - 40° - 90° - z
= 180° - 40° - 90° - 20°
= 30°

Answer:
a. 18
b. 17/36
d. 157.5615
e. 19.8
Step-by-step explanation:
Hope this helped!
Answer:
a. 18 b. 15/64 c. 122 2/9 d. 157.5615 e. 19.8
Step-by-step explanation:
a.
b. multiply across, so 1 * 15 = 15, 4*16=64, 15/64 can't be reduced, so done
c. 13 3/4 * 7 8/9, you must convert to improper fractions to multiply
4*13+3 = 55 so the first part is 55/4, 7*9+8=80 so the second is 80/9
55/4 * 80/9 = (55*80) / (4*9) = 4400 / 36, both are divisible by 4 so can be reduced to 1100/9 which cannot be reduced any further, 1100 + 9 = 122 R 2 so
1100/9 = 122 2/9
d. used calculator
e. 33% of 60 = (33//100)*(60/1) = (33*60) / (100*1) = 1980 / 100 = 19.8

A remodeling project calls for sanding a chair with a disk sander. The sanding disk used on the sander has a radius of 4 inches. Find the area of the disk. Use 3.14 for \large \pi
Answer:
the area of the disk is 50.24 inches^2
Step-by-step explanation:
The computation of the area of the disk is as follows:
As we know that
The area of the circle is
= πr^2
= 3.14 × 4^2
= 3.14 × 16
= 50.24 inches ^2
hence, the area of the disk is 50.24 inches^2

Step-by-step explanation:
If the cost of manufacturing mobile phones is $10,000 for the factorytime plus $80 per phone and that each
phone sells for $100, how many phones must be manufactured for the mobile phone manufacturer to
break even (when costs equals revenue)?
Answer:
500 phones
Step-by-step explanation:
cost of manufacturing: y = 80x + 10,000
money from phone sales: y = 100x
* note: x = #phones
solve for when they're equal;
100x = 80x + 10,000
100x - 80x = 80x - 80x + 10,000
20x = 10,000 –––––––––––> divide both sides by 20
x = 500

Suppose your school costs for this term were $4780 and financial aid covered 3/4 of that amount. How much did financial aid cover? How much do you still have to pay?
Answer: Amount covered by financial aid=$3,585
Amount left that you have to pay =$1,195
Step-by-step explanation:
School cost for the term = $4780
Amount covered by financial aid = 3/4 of $4780
= 3/4 x 4780
Amount left that you have to pay=School cost for the term -Amount covered by financial aid
= $4,780 - $3,585
Amount left that you have to pay =$1,195

Hassan plotted point M in the coordinate plane below.
On a coordinate plane, Point M is 0.5 units to the left and 0.25 units down.
He says that the plotted point is (0.5, 0.25). What is Hassan’s error?
The x- and y-coordinates are switched.
Both coordinates should be negative.
The x-coordinate should be -2.
The y-coordinate should be -1.
Answer:
Both coordinates should be negative
Step-by-step explanation:
When you go to plot a point, you always start at (0,0). Since you go left 0.5 units, that would put you at -0.5, then you go down 0.25 units which would put you at (-0.5, -0.25). The result would be (-0.5, -0.25). Hope this helps! :)
