Answer:
3 hours
Step-by-step explanation:
We can use ratios to solve
30 km 45 km
--------- = ---------------
2 hours x hours
Using cross products
30 * x = 2 * 45
30x = 90
Divide each side by 30
30x/30 = 90/30
x = 3

1. Yes Molly is correct, the formula of a parallelogram and rectangle are the same, length times width. She is correct because to find the area of a parallelogram you have to move one of its pieces to make it a rectangle
2. 4x square centimeters where x = one triangle (if they are all the same area)
or its (width times length times 1/2) times 4
3. I dont understand how to "measure it" sry
4. The rectangle would have the same area as the square (if they have the same dimensions) because they have the same formula to find the area.
5. The area of the trapezoid (i dont know how to find that but i think they mean the formula) which is the two bases of the trapezoid added together divided by 2 and lastly multiplied by its height or a +b/2 times h

4= 5(p -2 ) pls solve it ASAP
Answer:
p=14/5
Step-by-step explanation:
first distribute 5(p-2)
4= 5p-10
(imma just switch the equal sign to the right because i do it that way and i find it ez)
5p-10= 4
add 10 to each sides
5p-10+10=4+10
5p=14
p=14/5

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

you bought a magazine for $5 and four erasers. you spent a total of $25. how much did the eraser cost?
Answer:
1 eraser = $54 erasers = $20Step-by-step explanation:
Given that,
→ Magazine = $5
→ Total cost = $25
→ 1 eraser = x
The equation will be,
→ 4x + 5 = 25
Now the value of x will be,
→ 4x + 5 = 25
→ 4x = 25 - 5
→ x = 20/4
→ [ x = $5 ]
Hence, value of x is $5.

Which letter shows the number 4 2/3 on the number line?
Answer:
is there a picture?? -by-step explanation:
Could anyone help me with this problem, Quickly Please...
Answer:
3/4
Step-by-step explanation:
Since (p, r) lies on the line y = x + b,
we have,
r = p + b -----eq(1)
Since (2p, 5r) lies on the line y = 2x + b,
we have,
5r = 2(2p) + b -----eq(2)
Sub the value of r from eq(1) in eq(2),
5(p + b) = 4p + b
⇒ 5p + 5b = 4p + b
⇒ 5b - b = 4p - 5p
⇒ 4b = -p
⇒ b = -p/4
sub in eq(1)
r = p + (-p/4)
= p - p/4
= 3p/4
⇒ r = 3p/4
⇒ r/p = 3/4
Answer:
3/4
Step-by-step explanation:
We have two lines:
r = p + b eq(1)
5r = 4p + b eq(2)
eq(2) - eq(1)
4r = 3p
dividing by 4p
r/p = 3/4
