a rectangle has a length 8 cm the rectangle has area 20cm^2 the length of the rectangle is increased by 2 cm the area of the rectangle is increased by 4 cm^2 noh says the width of the rectangle decreased less than 5% is noah correct
9514 1404 393
Answer:
yes
Step-by-step explanation:
The width of the rectangle is given by ...
W = A/L
W = (20 cm²)/(8 cm) = 2.5 cm
__
The modified rectangle has a length of (8 cm +2 cm) = 10 cm, and an area of (20 cm² +4 cm²) = 24 cm². Its width will be ...
W = (24 cm²)/(10 cm) = 2.4 cm
The percentage change in size is ...
((2.4 cm)/(2.5 cm) -1) × 100% = -4%
The width of the rectangle decreased less than 5%. Noah is correct.
this is the formula which I am asking you all
Answer:
That is literally still the same formula for mean.

The radius of a cylindrical water tank is 6.5 ft, and its height is 19 ft. What is the volume of the tank? Use the value 3.14 for pi, and round your answer to the nearest whole number. Be sure to include the correct unit in your answer. (ft, ft^2, or ft^3)
Answer: 2521.91 ft^3
Step-by-step explanation:
Answer:
Step-by-step explanation:
Using the cylinder volume formula, V = (pi)r^2h
Since the radius and the height have already been given, no further calculations are necessary.
V= (pi)(6.5)^2(19)
V=(3.14)(42.25)(19)
2520.635 ft^3

3. A rectangular floor of dimensions
8.4 m x 5.4 m is to be tiled with right-
triangular marble pieces, with base 40 cm
and height 30 cm. How many marble
pieces will be required to cover the floor?
Answer:
area of the floor = 540*840.
=453600 cm sq.
area of the marbal piece = 1/2 * 40* 30 = 600 cm sq.
now,
no. of marble piece reqd. = 453600 / 600 = 756 marbal piece.

To find these out you have to use the strategy of P (parenthesis) E (exponents) M (multiplication) D (division) A (addition) S (subtraction)
3 - 4 x 2 The first thing you need to do is do the multiplication part first, since subtraction is the last thing you need to do. You multiply 4 and 2 and get the answer of 8, then subtract 3 which is 5
5 x 3 - 4 The first thing you need to do is multiplication 5 x 3 which equals 15 and then do 15 - 4 = 11
15 ÷ (3 x 5) x 2 The first thing you do is you do the P (parenthesis) which is (3x5) which equals 15. Then you multiply 15 with 2 which is 30 and then divide 30 with 15 which is 2
5 + 3 x 2 ÷ 6 First you need to do the Multiplication which is 3 x 2 which equals 6, and then you do the division, which is 6 ÷ 6 which is 1. Then add 5 to the 1 which is 6.

Jackie has a maximum of $450 to spend on shirts and jeans. The shirts she wants to buy are $12 each, including tax. The jeans she wants to buy are $27 each, including tax. What is an inequality that represents all possible combinations of s, the number of shirts, and j, pairs of jeans, Jackie can buy
Answer: 12s+27j≤450
Step-by-step explanation:
From the question, we are informed that Jackie has a maximum of $450 to spend on shirts and jeans and that the shirts she wants to buy are $12 each, including tax while the jeans she wants to buy are $27 each, including tax.
The inequality that represents all possible combinations of s, the number of shirts, and j, pairs of jeans, Jackie can buy will be:
= 12s+27j≤450
Sasha missed 20% of the problems on Coach Bristo's Test. The test had a total of 85 problems. How many problems did Carrie get correct on the test?
Answer: 68 correct
Step-by-step explanation: 20% of 85 is the same thing as 85 times 0.2. that equals to 17. She got 17 wrong, so 85-17 equals to 68. She got 68 problems correct and 17 wrong.
The answer to this question is 68.
85 x 20%= 17
85 - 17 = 68
The rule of thumb in filmmaking is that you must shoot at least 3 minutes of film for every minute in a movies “final cut”. A 30 minute roll of film cost $250. How much will film cost to make a 90 minute movie?
I can't figure out the process of solving it!!!
P.S: It needs to be set up as an inequality
PLS HELPP
Answer: $750
Step-by-step explanation:
We can solve this using direct proportion.
Let the number of minutes used be x
Let the cost be y
For direct proportion,y = kx
where, y = 250, x = 30
y = kx
250 = 30k
k = 250/30
k = 8.33
The cost to make a 90 minute movie will be:
y = kx
where,
y = unknown
k = 8.33
x = 90
y = 90 × 8.33
y = $750
The cost to make a 90 minute movie is $750.

Question:
The data presented in the table can be represented by a linear model.
1. What is the y-intercept of the data, and what does the y-intercept of this model represent?
2. What does the slope of this model represent?
Answer:
The y intercept it 0 hours and 44
In this model y intercept represnts the lowest possible score obtainable due to lowest study.
The slope shows there is a direct correlation as x increases so does the value of y so it has a positive slope. All it represents is the more they studied the higher they score
