Answer:
i. Average velocity = 11.11 m/s
ii. Displacement of the bus is 20000 m due east.
Step-by-step explanation:
The displacement of an object is the distance covered towards a definite direction, while the velocity of an object is the rate of its displacement in a given time.
average velocity = [tex]\frac{displacement}{time taken}[/tex]
But,
20 km = 20 000 m
30 minutes = 30 x 60
= 1800 s
So that,
average velocity = [tex]\frac{20000}{1800}[/tex]
= 11.1111
average velocity = 11.1 m/s
The displacement of the bus is 20 km due east.
If 3)% of a number is 105, what is 40% of that number.
pls help me soon thanks I will give brainliest
Answer:
140
Step-by-step explanation:
30% of a number(x) is 105. To find the number(x) we must set up the equation below and solve for x:
0.3=105/x (multiply x)
0.3x=105 (divide by 0.3)
x=350
Solve for 40% of the number by multiplying 0.4 by the number:
350x.4=140

Answer: 62.4 computers or 62
Step-by-step explanation:
Use this equation
48(n)
n will be 0.30 since the sales must increase by 30%
48(0.30)
14.4
Now add 48 and 14
48+14.4
62.4 or round it down to 62

Samantha works part time at a store where she earns $462.30 each month. Write an expression that could be used to find the amount Samantha earns working any number of months, m.
Answer:
462.30m
Step-by-step explanation:
1 month = $462.30
You multiply by the number of months to find how much she made over that time so $462.30 * m = 462.30m

Find the area of the composite figure.
Answer:
Area = 139.27 m²
Step-by-step explanation:
Area of the composite figure = area of rectangle + area of semicircle
= (L*W) + ½(πr²)
L = 10 m
W = 10 m
r = ½ of 10 = 5 m
Plug in the values
Area = (10*10) + ½(π*5²)
Area = 100 + 39.27
Area = 139.27 m²

Answer:
146.96 [tex]m^2[/tex]
Step-by-step explanation:
1. Approach
Divide this figure into two smaller shapes. Calculate the area of these smaller shapes, and then add the results. One can divide this shape into a semi-circle, and a triangle.
2. Area of the triangle
The formula to find the area of a triangle is;
[tex]\frac{base*height}{2}[/tex]
It is given that the base of the triangle is (14m) and the height is (10m). Substitute in these values, and solve for the area,
[tex]\frac{14*10}{2}\\= \frac{140}{2}\\= 70[/tex]
2. Area of the semi-circle
The area of the semi-circle can be found by finding the area of the larger circle, and then divide it by 2, since a semi-circle is half of a circle. The formula for the area of a semi-circle is;
[tex]\frac{(pi)(r^2)}{2}[/tex]
Where (pi) is the constant (3.1415...), (r) represents the radius of the circle, which by definition is half of the diameter. Substitute in the values and solve;
[tex]\frac{(pi)(7)^2}{2}\\= \frac{3.14*49}{2}\\=76.96[/tex]
3. Find the total area;
Now add up the two values for the area of the figures;
Triangle + Semi-circle
= 70 + 76.96
= 146.96

Jing is helping the kindergarten teacher put together bags of crayons. Each bag has 4 crayons, and 1/4 of the crayons in each bag are green. What fraction of the crayons in 3 bags is green? A. 3/12 B. 3/4 C. 4/3 D. 12/3
Answer:
A. 3/12
Step-by-step explanation:
1/4 x 3 for the three different bags and each bag having 1 crayon that's the color green it's 1/4 however due to there being 4 crayons in each bag
the only other answer could be 1/4 when simplified
Answer:
Step-by-step explanation:
1 bag of crayons = 4 crayons = 100% (10/10)
1/4 bag of crayons = 1 crayon = 25% = 1 green crayon per bag
3 bags of crayons = 12 crayons (3 x 4)
if 1 bag has 1 green crayon and there are 3 bags then there are 3 green crayons
A. 3/12

a. 16 x 8 + 24
b. (16 ÷ 8) + 24
c. 24 − 8 + 16
d.(16 − 8) + 24
Answer:
Change the minus sign to a plus. 2. ... 24. = 8. 11. 24. Find each quotient. 1. 1. 3. 1. 6. 2. 5. 8. 1. 16. 2. 1. 3 x. 6. 1 = 6 ... Write a variable expression to represent the word phrase.

Multiply and then simplify completely: ( 8 + √ 10 ) ( 8 − √ 10 )
Answer:
54.
Step-by-step explanation:
( 8 + √ 10 ) ( 8 − √10)
= 8*8 - 8√10 + 8√10 +√10 * -√10
= 64 - 8√10 + 8√10 - 10
The 2 middle turns cancel out so we have:
64 - 10

Which linear inequality represents the graph
OW!
(-2, 3)
-5
(0, -2)
Answer:
It has a negative slope, so B and C are eliminated. The graph also has a solid line instead of a dashed line. This means D is eliminated because it is only greater than. If the graph had a dashed line, then D would be correct, but it does not. So then the answer is A
