A dividend is greater than 1,000
The quotient is 52 with a remainder of 18
please help me, fast!
Answers
Dividend (D) > 1,000
Quotient = 52
Remainder = 18
Based on these criteria, we can set up the equation as follows:
D = Quotient × Divisor + Remainder
Since the quotient is 52 and the remainder is 18, the equation becomes:
D = 52 × Divisor + 18
To meet the criteria that the dividend is greater than 1,000, we need to find a suitable value for the divisor. We can do that by rearranging the equation:
D - 18 = 52 × Divisor
Now, let's choose a value for D that is greater than 1,000. For example, let's use D = 1,500:
1,500 - 18 = 52 × Divisor
1,482 = 52 × Divisor
Dividing both sides by 52:
Divisor = 1,482 / 52
Simplifying:
Divisor ≈ 28.5
Therefore, the expression that satisfies the given criteria is:
Dividend (D) = 1,500
Quotient = 52
Remainder = 18
Divisor ≈ 28.5
The equation becomes:
1,500 = 52 × 28.5 + 18

Answer:
Step-by-step explanation:
There are at least 2 ways you could do this. The best way is to use algebra. The trick is to equate 0.444444 to x, and then create a second equation by multiplying the first equation by 10. In doing this, you can subtract the two equations and that will get rid of the decimal.
10x = 4.444444...
x = .444444... Now subtract these 2 equation
9x = 4 Divide both sides by 9
9x/9 = 4/9
x = 4/9.
Since you are given choices, you could put each one into your calculator.
1/9 = 0,111111 not the answer.
40 /99 = 0.40404040 which is close but not the answer.

Area of a rectangle A=L*WArea of a triangle A=1/2*B*H (1/2* the length of the base* the length of the height) The area of the rectangle will be A=18*10= 180 The area of the tringle will be A=1/2*8*6= 24 Your answer will be 204 ft^2Answer: 204 Sq. Ft.
Step-by-step explanation:
Length Of Rectangle= 18 Ft.
Breadth Of Rectangle= 10 Ft.
Formula For Area Of Rectangle= Length x Breadth
= 18 x 10 Sq.ft.
=180 Sq. Ft.
Breadth Of Rectangle + Height Of Triangle = 18 Ft.
So, Height Of Triangle = 18 - 10 ft
= 8 Ft.
Base Of Triangle = 6 Ft.
Formula For Triangle Area = \(1/2\) x Base x Height
= 1/2 x 6 x 8 Sq. Ft.
= 24 Sq. Ft.
So, Sum Of Area Of Rectangle And Triangle = 24+ 180 Sq. Ft.

Answers
Answer: The answer is "experiment."
Step-by-step explanation:
This procedure is being used in order to validate a hypothesis, particularly in a research study. In the situation above, you have to validate whether a new reading program can increase reading comprehension or not.
The experiment consists of independent, dependent, and controlled variables. The independent variables are the ones being changed by the researcher, while the dependent variables tell whether the changes in the independent variable is significant. The controlled variables are the ones that are constant.
The dependent variable above is reading comprehension, while the new reading program is the independent variable. Examples of controlled variables are the ages of the participants. The age directly affects the reading comprehension, thus it has to be considered.
The two plots below show the heights of some sixth graders and some seventh graders:
Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot above the third mark, 1 dot above the fourth mark, 3 dots above the fifth mark and 1 dot above the sixth mark.
The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.8. Approximately how many times the variability in the heights of the seventh graders is the variability in the heights of the sixth graders? (Round all values to the tenths place.)

They decide to buy a coffee machine and as many bean bags as possible.

The coffee machine costs £320.
How much will they have left over from the £1,400?
Answers
9514 1404 393
Answer:
£27
Step-by-step explanation:
If we assume that more than 10 bean bags will be purchased, their individual cost will be £45 - 10%×£45 = £40.50. Then the total cost of n beanbags and a coffee machine will satisfy the inequality ...
£40.50n +£320 ≤ £1400
40.50n ≤ 1080
n ≤ 26 2/3 . . . . . . . 26 is more than 10, so the discount will be applied
Only an integer number of beanbags can be purchased, so the purchase of 26 beanbags and the coffee machine will leave a left-over amount of ...
£1400 -(320 +26×40.50) = £1400 -1373 = £27
The employees will have £27 left over.

The answer is £27.

Banana Cupcakes

1 teaspoon vanilla extract

You will use the recipe above to answer the following questions:

How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

The post office charges $0.70 to send one letter, and there is a flat fee of $1.50.
How to determine the the flat fee (F) charged by the post officeTo find the cost of sending one letter, we need to determine the flat fee charged by the post office.
Let's denote the flat fee as 'F' and the cost per letter as 'C'.
From the given information, we can set up the following equations:
Equation 1: F + 35C = 26
Equation 2: F + 18C = 14.10
We can solve this system of equations to find the values of F and C.
First, we subtract Equation 2 from Equation 1 to eliminate F:
(F + 35C) - (F + 18C) = 26 - 14.10
17C = 11.90
Now, we divide both sides of the equation by 17 to solve for C:
C = 11.90 / 17
C ≈ 0.70
Therefore, the cost to send one letter (C) is approximately $0.70.
To find the flat fee (F), we can substitute the value of C into either Equation 1 or Equation 2. Let's use Equation 1:
F + 35(0.70) = 26
F + 24.50 = 26
F = 26 - 24.50
F = 1.50
Therefore, the flat fee (F) charged by the post office is $1.50.

When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.
When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.
