Patterns are made using straight lines and arcs.
Pattern A (one row)
Pattern B (two rows)
More rows are added to Pattern B so that
number of straight lines : number of arcs = 7:6
How many rows are added?
5 rows are to be added in the pattern if the ratio will be 7:6 between number of straight lines.
What is a pattern?
A pattern is a sequence. It can be an AP, GP also.
How to determine the number of rows to be added?
present ratio between number of straight lines and number of arcs
=8:9
When we add 1 row it will increase 4 straight lines and 3 arcs. So when 5 rows are added it will increase 20 straight lines and 15 arcs.
Then total number of straight lines will be 28 and the total number of arcs will be 24 and the ratio will be 28:24 which after dividing by 4 becomes 7:6.
Hence 5 rows are to be added in the pattern B to get the ratio 7:6.

Area of figure=(10×8)+(1/2×6×8)
=80+24

Math help please show work
Answer:
Step-by-step explanation:
To overestimate the area would mean that you completely enclose the circle in squares; an 8 x 8 square to b exact. The area of a square with sides measuring 8 is 64. The overestimation is 64.
To underestimate the area would mean that you only count the squares that are completely inside the circle. That would be a 6 x 6 square (even though the 6th squares are a tiny bit outside the circle). A square with sides of 6 has an area of 36. The underestimation is 36.

Answer:
Step-by-step explanation:
Range is y thing, where as domain is an x thing. The way you state a range (or a domain, for that matter) is to start from the low point on the graph and go up to the high point. Our graph doesn't have a starting point; therefore, the "low" end of the graph comes up from -∞. The high point on the graph maxes out at 3. Therefore, the proper way to state the range (depending upon whether you use set-builder or not) is
R = (-∞, 3] or another way to state this is
R = {y | y ≤ 3} which reads "y such that y is less than or equal to 3".
. The temperature on Monday was −5∘C . By Tuesday the temperature rose to −2∘C. Find the change in temperature.
Answer: [tex]3^{\circ}C[/tex]
Step-by-step explanation:
Given
The temperature on Monday was [tex]-5^{\circ}C[/tex]
By Tuesday, it becomes [tex]-2^{\circ}C[/tex]
Change in temperature is the difference between the two temperatures.
[tex]\Rightarrow \Delta T=-2-(-5)\\\Rightarrow \Delta T=-2+5\\\Rightarrow \Delta T=3^{\circ}C[/tex]
Therefore, the change in temperature is [tex]3^{\circ}C[/tex].

The ratio of the number of red balls to yellow balls in a bag is 4:5. There are 270 balls in
the bag. Which statement is TRUE?
Answer:The ratio of the number of red balls to yellow balls in a bag is 4:5 there are 270 balls in the bag
Step-by-step explanation:
As per linear equation, there are 120 red balls and 150 yellow balls in the bag.
What is a linear equation?A linear equation is an equation that has one or multiple variables with the highest power of the variable is 1.
Given, the ratio of the number of red balls to yellow balls in a bag is 4:5. There are 270 balls in the bag.
Let, there are 4x red balls in the bag.
Therefore, there are 5x yellow balls in the bag.
Now, (4x + 5x) = 270
⇒ 9x = 270
⇒ x = 270/9
⇒ x = 30
The number of red balls = 4x = 4 × 30 = 120.
The number of yellow balls = 5x = 5 × 30 = 150.

WILL GIVE BRAINLIEST AND THANKS. determine if these are tangent to the circle
Answer:
19 Five is not tangent to the circle.
20 Eight is tangent to the circle.
Step-by-step explanation:
In order for one of the legs to be a tangent to a circle, the length must be part of a right angle triple.
I don't think the diagram on the left is, but I'll check it.
5^2 + 12^2 =
25 + 144 =
169
square root of 169 is 13
The length of the hypotenuse should be 13 not 14. Fourteen does not make Pythagorean triple. 13 would. So the line 5 units long does not make a tangent to the given circle.
The diagram on the right is a different story. 6 8 and 10 do make a Pythagorean triple, even though the two diagrams are not the same.
The radius and the distance to the external point form a right angle.
The Pythagorean triple is
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100

The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
[tex] \frac{2.3 + 0.3 + 7 + 6.1 + 9.7}{5} [/tex]
