Answers
Answer:
The change in altitude per minute is 63.5 alt/ min
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
In 24 minutes = 1524 feet
So, the average Change in altitude per minute
=1524/24
= 63.5 alt/ min
hence, change in altitude per minute is 63.5 alt/ min.

Jamie buys 3 snacks and 2 bottles of juice. Each snack costs $0.75, and each bottle of juice costs j dollars. The total cost of the snacks and bottles of juice is $6.75. Which of the following equations could be used to find the cost of a bottle of juice, in dollars?
Answers
Answer:
2.25+2j=6.75
That is the answer I got
Step by step
Since you didn’t give options I will give you my equation.
3 snacks * .75 + 2 juice * x unknown $ = 6.75
3(.75) + 2j = $6.75 is the equation
Solve
2.25 + 2j = 6.75
Subtract 2.25 from both sides to isolate j
2.25 - 2.25 + 2j = 6.75 - 2.25
2j = 4.50
Divide both sides by 2 to solve for j
j = $2.25

Answer:
3. The first one.
4. The last one.
Step-by-step explanation:
For 3, first I looked to see what direction the greater than symbol was facing. Since it is pointing right, I know the arrow has to go right on the number line. Then, since it's only a greater than symbol, the dot is empty.
For 4, I used the same method as stated above. Greater than symbol means arrow goes to the right. However, since this symbol has a line underneath it, it is a greater than OR equal to symbol. This means the dot will be solid instead of empty.

Answer:
On blueprint , length of room is given by feet and width is given by 10 feet.
Step-by-step explanation:
Given: On a blueprint, the scale indicates that 6 cm represent 15 feet.
We have to find the value of the length of a room that is 9 cm long and 4 cm wide on the blueprint.
Since, the scale indicates that 6 cm represent 15 feet
That is 6 cm = 15 feet
1cm = feet
Thus, the scaling factor for 1 cm is feet.
Thus, for length of a room is 9 cm long.
On blueprint , length is given by feet.
Also, given width of room is 4 cm
On blueprint , width is given by feet.
Step-by-step explanation:
Answer: so it would be the length is 27.2 feet and it is 8.88888889 feet wide or 8.9 ft wide and 27.2 feet long when its rounded i do hope i helped you and im so sorry if i didn't 27.2 goes in the box

Given the inequality 5(n − 4) < 4(n + 15), determine which integer makes the inequality false.
S:{80}
S:{15}
S:{5}
S:{−9}
Answers
Answer:
-9
Step-by-step explanation:
5(-9-4)
5(-13)
-65
4(-9+15)
4(6)
24
-65<24 so -9 is false because -65 is not smaller than 24
The solution is Option A.
The value of n which makes the inequality 5 ( n − 4 ) < 4 ( n + 15 ) false is when n = 80
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is given by
5 ( n − 4 ) < 4 ( n + 15 )
Now , on substituting the value of n as 80 in the inequality equation , we get
5 ( n − 4 ) < 4 ( n + 15 )
when n = 80
5 ( 80 - 4 ) < 4 ( 80 + 15 )
5 ( 76 ) < 4 ( 95 )
380 = 380
So , the inequality will become false as the two sides of the equation will result in value 380 when n = 80
Hence ,
The value of n = 80 in the inequality equation 5 ( n − 4 ) < 4 ( n + 15 ) will make it false

0.056 dividing by 0.004
explain how you got the answer for this problem
Answers
First, you need to make the divisor a whole number, and then you make the dividend a whole number.
1.) 0.0056 divided by 0.004 = (0.0056 x 1000) x (0.004 x 1000)
You should make it a whole number by multiplying it by a power of ten.
2.) *5.6 divided by 4
Then divide.
3.) Answer : 0.0056 divided by 0.004 = 1.4
Answer: the answer is 14
Step-by-step explanation:0.056/- 0.004 as a percent value (as a percentage)
Detailed calculations below
Fractions: brief introduction
A fraction consists of two numbers and the fraction bar:
0.056/- 0.004
The number above the fraction bar is the numerator: 0.056
The number under the fraction bar is the denominator: - 0.004
To get the fraction's value, divide the numerator by the denominator:
The value = 0.056 ÷ - 0.004
Percent, p%: short introduction
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% = p/100 = p ÷ 100.
How to convert a fraction to a percentage:
1) Calculate the value of the fraction.
2) Multiply this number by 100.
3) Add the percent sign %
Convert the fraction to a percentage
1. Calculate the value of the fraction.
To get the fraction's value, divide the numerator by the denominator:
0.056/- 0.004 =
0.056 ÷ - 0.004 =
- 14
A quick note:
100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100
... and its value doesn't change.
n × 100/100 = n × 1 = n, any number n

Barry is given 0.4 and 0.9 cents
He already has 6.30 in his bank
0.4+0.9 = 1.3
add the money he was given to the bank
1.3 + 6.3 = $7.60
Barry has $7.60 in total.
2. $3.70Henry buys two candy bars, one is worth 3.20 and the other is 1.60
add them up to get the total
3.20 + 1.60 = 4.80
Henry has $8.50
subtract the cost of the chocolate from the money he has
8.50 - 4.80 = $3.70
Henry has $3.70 left over from the $8.50
3. $7.20Beth buys a bouncy ball worth 1.20 and pen that is 5 times that amount.

Here, we need to apply basic mathematical operations and solve the given linear equation. We get the value of a = -4.
Linear equations are expressions that involve variables and constants raised to the power of 1 (i.e., the exponent is 1) and are represented as a straight line when graphed on a coordinate 2D axis. A linear equation can be written in the form ax+ b = c where x is a variable and a,b, and c are constants .
Linear equations can have one variable (univariate) or multiple variables (multivariate). Also, these variables should not be squared, cubed, or raised to the power of any constant other than 1. For example,
1. 2x+5=0 (univariate)
2. 4z+2w=5x(multivariate)
The question given to us is an univariate linear equation where to have to apply basic rules of mathematics. Firstly we need to divide 56 by 14 which gives us 4. The negative sign gives our answer as -4.
