Answer:
3cm²
Step-by-step explanation:
Since the sizes are square tiles, to know the tile's side lengths that Dorian need to estimate, we will use the formula for calculating the area of q square
Area of a square = L²
L is the side length of the tiles
For the tiles with area 7cm²
7 = L²
L² = 7
L = √7
L = 2.65cm
For tiles with area 5cm²
5 = L²
L² = 5
L = √5
L = 2.24cm
For tiles with area 9cm²
9 = L²
L² = 9
L = √9
L = 3.0cm
Since for all the square tiles the length of the tile is ≤ 3 cm, then the tile's side lengths that Dorian will need to estimate is approximately 3cm

llene is making bows for gift wrapping. She uses 1 feet of ribbon for each 3 bow. How much ribbon will she need to make 12 bows?
Answer:
4 feet
Step-by-step explanation:
Because if she used 1 feet of ribbon for 3 bows you need to multiply by 4 to 1 foot and you will get 12 bows
Answer:
4 feet of ribbon
Step-by-step explanation:
Because she uses 1 feet of ribbon for each 3 bows, we can create a fraction.
1 ft / 3 bows = x ft / 12 bows
Cross multiplying, we get: 3x = 12
Divide by 3 and we get x = 4 (x in this case is in feet)

determine if the equation is true x = 8
2x - 6 = 9
Answer:
False
Step-by-step explanation:
This is false because:
1) In order to solve this, we cam use the addition property of equality
2) First, you can add 6 to -6 and 9
New Equation: 2x = 15
3) Now divide 2 with 2 and 15
New Equation: x = 7.5
You can also check by inserting 8 into the equation.
2(8) - 6 = 9
16 - 6 = 9, this is not true.
Therefore, this statement is false. x = 7.5

Find g(3), given that g is a linear function with g(1)=-2 and g(4)=8
Answer:
14/3
Step-by-step explanation:
linear equation slope passing (1,-2), (4,8)= 8-(-2) / 4-1 = 10/3
g=10/3 x +b, substitute (1,-2) to solve b
-2=10/3 (1) +b, b=-16/3
thus, g=10/3 x - 16/3
when x=3, g=14/3

Answer:
9 is the constan trate of change.
Step-by-step explanation:
Assuming two points of the graph with the form as P=(x,y) you can find the constant rate m using the slope formula.
m=(y2-y1)/(x2-x1)
Lets say that P1=(0,0) and P2=(1,9), then:
m= (9 – 0)/(1-0)
m=9
Therefore, the point (0,0) means that when you are not buying any t-shirt then you dont have any waste of money. The point (1,9) means that when you are buying one t-shirt then you have to pay 9 then its result that cost of each t-shirt is 9 so when you are buying two t-shirt then you have to pay 18, when you are buying three you have to pay 27 likewise.
write 1.359 x 10^5 in standard form
The given number is already in the standard form i.e. 1.359 x 10⁵.
What is standard form?Standard form refers to any number that may be expressed as a decimal number between 1.0 and 10.0 when multiplied by a power of 10.
When working with extremely big or extremely small numbers, standard form, also known as standard index form, may be quite helpful. It is based on the use of powers of 10 to describe the size of a number.
Scientists may compare the orders of magnitude of various values using standard form, which enables them to understand events and make helpful predictions.

60 pages in 2 days
Step-by-step explanation:
120 pages in 4 days is equivalent to a 30 pages in 1 day rate (divide both by 4). The only other rate that is equivalent to a 30 pages in 1 day rate is 60 pages in 2 days because 60 = 30*2 and 2 = 1*2.
Answer:
60 pages in 2 days is the answer
Sam purchases a used video game for GameStop. In order to make a profit,
GameStop marksup their used game 50% before reselling them. Sam paid $45 (without
tax). What was the original price of the game?
Answer:
$22.50
Step-by-step explanation:
50/100 = x/45
cross multiply
50 × 45 = 100 × x
2250 = 100x
divide both sides by 100
22.5 = x
*note: marksup the price means that $45 should be more than what the value of x is. $45 is more than $22.50. you can also check your work by looking at the fact $22.50 is exactly half (50%) the amount of $45*

What is the slope of the line that passes through points (-6,-7) and (-24,-7) . Write your answer in the simplest form
Answer:
The slope of the line passing through both points is 0
Step-by-step explanation:
Mathematically, we can calculate the slope as follows;
m = (y2-y1)/(x2-x1)
where (x1,y1) = (-6,-7)
(x2,y2) = (-24,-7)
Thus m = (-7 -(-7))/(-24 + 6) = 0/18 = 0
The slope of both is 0

Complete Question:
Michael's family was traveling to visit prospective colleges. They drove to the closest college that interested him, took a tour, and then drove to another college a little farther from home. The graph shown represents the situation.
Part A:
Enter a number in search box to complete the domain and range.
Domain ___ ≤ x ≤ ___
Range ___ ≤ y ≤ ___
Part B:
Is the statement, "the graph is continuous", true or false?
Answer:
Part A:
Domain: 0 ≤ x ≤ 5
Range: 0 ≤ y ≤ 300
Part B: True
Step-by-step Explanation:
Part A:
The domain of the function represented on the graph includes all values x plotted in the x-axis, which represents the time (hrs) travelled during the tour.
The domain is [0, 5]. The journey started at 0 mins and ends at 5 mins.
Domain can be represented as 0 ≤ x ≤ 5
The range of the function includes all values on the y-axis of the function that are plotted on the graph. The range is the set of distance covered from from during the tour.
Range is [0, 300].
This can be represented as 0 ≤ y ≤ 300.
The maximum point is at the point on the graph, when x = 5, and y = 300. This implies that it took them 5 mins to cover 300 miles during the tour.
Part B:
The graph is continuous because the line of the graph has no breaking point from start to finish.
The statement is true.

mZBAC =
mZCAD =
Answer:
In the pic
Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)
The ∠BAC is 58° and ∠CAD is 32° for the given figure.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
Given,
∠BAD = 90°
Since,
∠BAD = ∠BAC + ∠CAD
15x - 2 + 7x + 4 = 90°
22x = 88 ⇒ x = 4
So,
∠BAC = 15(4) - 2 = 58°
And
∠CAD = 7(4) + 4 = 32°
Hence "The ∠BAC is 58° and ∠CAD is 32° for the given figure".
