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

Answers

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

77 meters this is correct trust. My word dog

Theresa's Book Barn sold $10,347 worth of books during September. In October, their sales were $12,115. How much higher were Theresa's book sales during October than in September? Explain how you got your answer.

Answers

Answer:

$1,768

Step-by-step explanation:

We know that Theresa's Book Barn sold $10347 worth of books in September, and $12,115 in October. Since we want to know how much higher the sales were in October than in September, we would have to subtract.

So, we would have to subtract the two numbers.

  12,115
- 10,347
    1768

Subtracting the two numbers gives us $1,768, which is the difference.

I hope this was semi-helpful-

Answers

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

Answers

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.

Which expression has the same value as 20 − 4 ⋅ 3
a. 20 − (4 ⋅ 3)
b. (20 − 4) ⋅ 3
c. 20 + 4 − 3
d. 20 ⋅ 4 − 3

Answers

Answer:

a. 20 - (4 ⋅ 3)

Step-by-step explanation:

PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

Please note that multiplication 4 ⋅ 3 will happen before the subtraction -

If we add parentheses, we introduce a new "order". But if the parentheses are around the first operation we perform, the order stays the same!

This means that answer a. must be correct.

We verify:

20 − 4 ⋅ 3 = 20 - 12 = 8

a. 20 − (4 ⋅ 3) = 20 - 12 = 8

b. (20 − 4) ⋅ 3 = 16 ⋅ 3 = 48

c. 20 + 4 − 3 = 21

d. 20 ⋅ 4 − 3 = 80 - 3 = 77

Answer: A: 20 - (4 x 3)

Step-by-step explanation:

In the end, the final answer is 8, so we need to see which one of these options give us 8. As seen, we first must solve the multiplication, and the first option, A, solves the multiplication first because it is in parenthesis, which gives us 8, so the correct answer is A.

So for the first one, you want to look at the ratio;
1 cm : 2 m and 1 cm : 4 m
This means that for every 2 meters you would draw one centimeter, or every 4.
Drawing B is the larger drawing because it uses a larger number of meters.

The second one is almost like the first, except for every 10 meters you draw 1 centimeter. 50 divided by 10 is 5 and 25 divided by 10 is 2.5 These are the centimeters.

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

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)

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator.

In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 8 = 32. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - nine quarters minus eleven eighths is seven eighths.

Step 1

Factor the numerator of the given expression.

Rewrite 64 as 4³ and 1 as 1³:

[tex]\implies (4^3)x^3-1^3[/tex]

[tex]\textsf{Apply the exponent rule} \quad a^b \cdot c^b=(ac)^b:[/tex]

[tex]\implies (4x)^3-1^3=(4x-1)\left(16x^2+4x+1\right)[/tex]

Step 2

Replace the numerator in the given expression with the factored numerator from step 1:

[tex]\implies \dfrac{64x^3-1}{4x-1}=\dfrac{(4x-1)\left(16x^2+4x+1\right)}{4x-1}[/tex]

Cancel the common factor (4x - 1):
