Answer:
240
Step-by-step explanation:
[tex]\frac{inches}{miles}\\\frac{2}{25}=\frac{19.2}{?}[/tex]
When doing proportions you multiply the numerator of one fraction by the denomenator of the other. Here the available pair is 19.2 and 25. This means that we multiply 19.2 by 25, which equals 480. The next step is to divide by the remaining numerator or denomenator. Here we divide 480 by 2, which equals 240.

Harry made a scale drawing of the elementary school. The schoolyard, which is 154 meters long in real life, is 22 millimeters long in the drawing. What scale did Harry use?
1 millimeter : __ meters
I'm sorry that there is no picture or drawing
Answer:
Based on the information given, the scale
that's used by Harry for drawing the schoolyard will be 1:7000.
Firstly, it should be noted that
meter = 1000 milliliters
Therefore, 154 meters = 154,000
millimeters
Since the schoolyard is 154 meters long in real life but is 22 millimeters long in the
drawing, then the scale will be:
= 22/154000
= 1/7000

Answer:
Answer is -1.25
Step-by-step explanation:'
You start by making sure everything in the problem is a decimal which means turning 1 1/4 into 1.25 and then adding the two numbers together -2.5+.25=-2.25
-2.25+1=-1.25
Brainliest would be nice.
Answer: -3.125 or -25/8
Step-by-step explanation:
I do not know what has been covered in your class, but the "x" appears to be multiplication here.
It would be best to convert into all decimals or all fractions.
For all fractions (I think is easiest):
-2.5 is -2 1/2 = -5/2 and then 1 1/4 = 5/4 (need improper fractions to multiply, then multiply straight across)
Then take -5/2 * 5/4 = -25/8 (multiply fractions by multiplying numerators together, then denominators together). If you need this as a mixed number, -25/8 is -3 1/8
For all decimals:
-2.5 is already as a decimal, then 1 1/4 = 1.25
So then multiply:
1.25 (I put 1.25 first because it has more digits)
x -2.5 (note- multiplying a positive by a negative gives you a negative)
6 2 5 (multiply 5x5 first, giving 25, so place 5 and carry the 2,
then multply 5x2 = 10 plus the 2 carried is 12, carry that 1
then 5x1 = 5 plus the 1 carried is 6)
+ 2 5 0 0 (0 placeholder first, now multiply the 2 by each digit of 1.25,
2x5 = 10, carry the 1, then multiply 2x2 = 4 plus the 1 carried
is 5, then multiply the -2 by the 1 , -2x1 = -2)
Now add the 625 + 2500 = 3125, there were 3 digits after the decimal originally, so move decimal back 3 places, giving 3.125. Finally, the answer is negative because you multiplied a negative number with a positive one. SO the final answer is -3.125 (also equal to the -25/8)

2.To lay a drainage system it costs $120 for every 50 feet. Write an equation to determine the cost of laying 300 feet of drainage.
3.Solve: 12 = -4h + 7 +11h
Which of the following would be an appropriate first step to take in solving for "h"?
Group of answer choices
adding 7 to both sides
adding 12 to both sides
combining (-4h) and (11h)
multiplying both side by 4
Answer:
$3.21
Step-by-step explanation:
Answer:
1: $3.21.
2: 50x+120=300
3: h=5/7/ first step would be to adding 7 to both sides.
Step-by-step explanation:
for the 3rd:
you're combining like terms so you have to subtract 7 from both sides you gotta subtract 12-7 so that gives you 5=7h+7-7 and the subtract the 7-7, and that will give you 0 so you have 5=7h left.divide both sides by the same terms (7), so you'll have 5/7 and 7h/7 so 7/7=0 so you drop that and just have the h. now switch sides with the virable and the fraction you still have (5/7)you now have h=5/7.This expression involves two numbers written in scientific notation.

Answer:

Step-by-step explanation:
1) Reorder the terms
3x + 5 = 29 - 9x
3x + 5 = -9x + 29
2) Subtract 5 from both sides
3x + 5 - 5 = -9x + 29 - 5
3x = -9x + 24
3) Add 9x to both sides
3x + 9x = -9x + 9x + 24
12x = 24
4) Divide both sides by the same factor
12x/12 = 24/12

Which of the following expressions are equivalent to minus, start fraction, 2, divided by, minus, 13, end fraction?
I will give Brainliest to whoever answers the best!
Answer:
Step-by-step explanation: The equivalent expression will be (-2)/ (-13) and-(-2/13) so option (A) and option (B) both will be correct. In such a fraction, the value that appears above the horizontal line is referred to as the numerator. It represents the number of pieces removed from the whole.
The denominator of a fraction is the numerical value that comes before the brings together various.
If we divide two numbers by each other than the upper word is called the numerator, and a lower word is called the denominator. For example, a fraction 1/5 here 1 will be the numerator and 5 will be denominated.
Given that now since the multiplication of - and - quantity is always positive so - and - is positive so it will be 2/13
If you take both options A and B in both options, the negative sign is going to be canceled and it will give a positive value.
Hence "The equivalent expression will be (-2)/ (-13) and-(-2/13)".

Jason wants to plant 66 carrot seeds and 44 onion bulbs. He would like to plant them so
that there are the same number of plants in each row and each row only has one type of plant. a. What is the greatest number of plants he can have in each row? SHOW YOUR
WORK
Answer:
Step-by-step explanation:
Since we need an equal amount plants in each row, you have to find the greatest common factor (GCF) of 66 and 44.
The factors of 44 are: 1, 2, 4, 11, 22, 44
The factors of 66 are: 1, 2, 3, 6, 11, 22, 33, 66
Therefore, the greatest factor of 66 and 44 is 22. This means Jason will have 3 rows of carrot plants and 2 rows of onion plants. Each row will have 22 plants.
Jason can have a maximum of 22 plants in each row. This allows him to place 22 onion bulbs or 22 carrot seeds in each row.
We need to determine the greatest common divisor (GCD) of 66 and 44 to determine the maximum number of plants Jason can have in each row while still adhering to the requirements of having the same number of plants in each row and each row having only one type of plant.
The GCD denotes the maximum number of plants he is permitted to place in each row.
Using the Euclidean algorithm to find the GCD:
1. Divide the larger number by the smaller number:
66 ÷ 44 = 1 with a remainder of 22.
2. Divide the smaller number 44 by the remainder 22: 44 ÷ 22 = 2 with no remainder.
3. Since there is no remainder, the GCD is the divisor in the last division, which is 22.
