Round each unit price to the nearest tenth of cent
28.374¢_______$
16.815¢_______$
20.098¢_______$
Explain how u rounded 20.098 to the nearest hundredth
Answer:
28.374 rounded is 28.37
16.815 rounded is 16.86
20.098 rounded is 20.10
Step-by-step explanation:
I rounded 20.098 to the nearest tenth by looking at the number in the tenths place and the number in the hundreds place. When you see the number in the hundreds place and it is 5 or more, you round the number in the tenths place up a number.
Find the ratio of 4km to 1200m
Answer:
10 : 3
Step-by-step explanation:
4km = 4000 m
4000 : 1200 = 4000/1200 = 40/12 = 10/3 = 10 : 3
Answer:
convert 4km into meter.
1200m/4000m

The distance from Cherotich's home to school is
2km 400m. He goes to school in the morning
and returns in the evening daily. What distance
does he cover from Monday to Friday?
Answer:
24 kilometers
Step-by-step explanation:
Given
Represent the distance with x
[tex]x = 2km\ 400m[/tex]
Required
The distance covered for 5 days (i.e. Monday to Friday)
First, we calculate the distance covered in a day
He covers the same distance when going to school and when coming back from school.
So, the daily distance is:
[tex]Daily = 2 * x[/tex]
[tex]Daily = 2 * (2km\ 400m)[/tex]
[tex]Daily = 4km\ 800m[/tex]
In 5 days, he covers:
[tex]5\ days = 5 * Daily[/tex]
[tex]5\ days = 5 * (4km\ 800m)[/tex]
[tex]5\ days = 5 * (4km+ 800m)[/tex]
Open bracket
[tex]5\ days = 5 * 4km+ 5 * 800m[/tex]
[tex]5\ days = 20km+ 4000m[/tex]
Convert m to km
[tex]5\ days = 20km+ 4km[/tex]
[tex]5\ days = 24km[/tex]

It cost Jocelyn $5.60 to send 56 text messages. How much would it cost to send 198 text messages?
Answer:
$19.80
Step-by-step explanation:
56÷5.60=.10
.10×198=19.8
Answer:
$19.80
Step-by-step explanation:
First, the unit rate of each text message is .1 so if we multiply 198 x .1 we get $19.80 which is your answer.

please answer quickly
Answer:
1) 6a - 2b
2) 2a + b
3) 2b + a
4) 4b - a
5) 3(a + b)
Step-by-step explanation:
2a + b ==> 2(3) + 5 = 6 + 5 = 11
2b + a ==> 2(5) + 3 = 10 + 3 = 13
3(a + b) ==> 3(3 + 5) = 3(8) = 24
4b - a ==> 4(5) - 3 = 20 - 3 = 17
6a - 2b ==> 6(3) - 2(5) = 18 - 10 = 8
Now order them from least to greatest
6a - 2b ==> 6(3) - 2(5) = 18 - 10 = 8
2a + b ==> 2(3) + 5 = 6 + 5 = 11
2b + a ==> 2(5) + 3 = 10 + 3 = 13
4b - a ==> 4(5) - 3 = 20 - 3 = 17
3(a + b) ==> 3(3 + 5) = 3(8) = 24

The measures of the angle of a triangle are shown on the figure below. Solve for X.
Internal angles sum: 180(sides-2) = 180
5x = 180 - (48 + 90 + 17)
x = 25/5
x = 5
answer: 5
proof:
(90 + 48) + (5(5)+17) = 180
Answer:
x=5
Step-by-step explanation:
We know that a triangle consists of 180°. So to start, you take the two given angles and add them together. 48+90=138.
Now you subtract the 138 from the total of 180 to get the degrees of the remaining angle. 180-138=42°.
Now set the unknown angle equal to 42. (5x+17) = 42
Subtract 17from both sides to get 5x=25
Divide 5 from both sides to get x=5

Can someone please give me the answer
Answer:
B
Step-by-step explanation:
Its at most $8000 so the line is going to point to the left. If it was the least then the line points to the right. So we can rule out D and A. Its at most $8000 so it could be $8000 leaving the answer to be B. In the answer choice C its below $8000 but not excally $8000

Step-by-step explanation:
If the point (2,-1)lies on the graph of y=f(x), then a point on the graph of y=f(2x) would be
Answer:
(1, -1)
Step-by-step explanation:
Since f(2x) is a horizontal compression by factor of 1/2, you multiply the x value of the coordinate by 1/2, so (2, -1) -> (1, -1)

Answer and Step-by-step explanation:
We are told that there is 24 cupcakes, which total up to be 36 dollars.
c will represent One cupcake.
We would do 36 divided by 24 to find the cost of One cupcake.
[tex]\frac{36}{24} = \frac{3}{2} = 1.5[/tex]
Each cupcake (c) is equal to $1.5.
Equations that would get us to this would be:
36/24 = c
36 = 24c
