Numerele a,b,c sunt rationale si verifica egalitatea 3a+4b=c-36. Determinati cele trei numere daca a si b sunt direct proportionale cu 4 si 3,iar b si c sunt invers proportionale cu 0,24 si 0,01
Answers
Answer:
a/4 = b/3 = k
a=4k
b=3k
0.24=24/100=6/25
0.01=1/100
6b/25 = c/100 = k'
b=25k'/6=3k =>k'=18k/25

the drawing at the right is a plan for an apartment. The length of each Square on the grid represents 1 cm. The scale from the apartment to the drawing is 8 ft to 1 cm long. Draw another scale drawing of the apartment using a scale from the apartment to the drawing of 4 ft to 1 cm. Justify why you're drawing is accurate
Answers
Answer: all sides of the apartment would be cut in half.
Step-by-step explanation:
To draw a scale drawing using a different scale, convert the measurements from the original scale to the new scale by dividing them by the ratio between the scales. The resulting measurements are then used to create an accurate scale drawing.
To draw a scale drawing of the apartment using a scale of 4 ft to 1 cm, we need to convert the scale from the given 8 ft to 1 cm to the new scale.
Since the new scale is half of the given scale, we can divide the measurements in the given drawing by 2
to get the corresponding measurements in the new drawing.
We then use these new measurements to draw the scale drawing of the apartment.
For example, if a wall in the given drawing is 16 ft long, in the new scale drawing it will be 8 cm long. We repeat this process for all measurements in the given drawing to create an accurate scale drawing based on the new scale.
This drawing is accurate because we followed the conversion process correctly and used the new scale to determine the appropriate measurements for the scale drawing.

A pack of 50 sheets of paper costs $1.10. What is the cost per
sheet of paper? Did you multiply or divide to find your answer?
a. $0.022, divide c. $55, multiply
b. $0.022, multiply d. $55, divide
Answers
Answer: Choice A
$0.022, divide
======================================================
Work Shown:
50 sheets = 1.10 dollars
50/50 sheets = 1.10/50 dollars
1 sheet = 0.022 dollars
In the second step, I divided both sides by 50 to get the "50 sheets" to turn into "1 sheet". The result of 0.022 dollars is equivalent to 2.2 cents; so the unit cost is a little over 2 cents per sheet.

Akio has 27 blankets and 18 flashlights to use in emergency relief kits for communities in need. He will put the same number of blankets and the same number of flashlights in each kit. He wants to use all the blankets and flashlights. What is the greatest number of emergency relief kits Akio can make?
Answers
Answer:
6
Step-by-step explanation:
The answer Is 6
Answer:
9
Step-by-step explanation:
We can make an equation out of this
So if he has 27 blankets, and 18 flashlights, he will need to divide evenly amongst the kits.
The equation would be
z=x+y, where x is the amount of blankets, and y is the amount of flashlights.
to find this, we need to find what 27 is divisible by, and what 18 is divisible by.
27 - 27, 9 , 3, 1
18 - 18, 9, 6, 2, 3, 1
Now, 18 and 27 are both divisible by 9
18/9=2
27/9=3
So we can make a total of 9 emergency kits, with each kit having 3 blankets and 2 flashlights
Hope this helps!!^^

Answer: 40
Step-by-step explanation:
4 x (x)/4 = 10 x 4 (4 ÷ 4 = 1, so they'll cancel out)
10 x 4 x 1 = 40
Step-by-step explanation:
so, the whole thing starts out as
x/4 = 10
the next 2 steps are written by your teacher :
multiply both sides now by 4
4 × x/4 = 10 × 4
on the left side (as your teacher stroke through)
4 / 4 = 1
leaving x all by itself.
on the right side
10 × 4 = 40
and you get
x = 40
and there is your result.
