1. Determine the relationship between the two triangles and whether or not they can be proven to be congruent.
Answer:
The two triangles are related by SAS, so the triangles are congruent.
Step-by-step explanation:
We can see that both of them have 2 similar sides, and 1 similar angle. This goes underneath the rule SAS, which makes the triangle congruent

1≤x≤5
The average rate of change of f(x) over 1 ≤x≤5 is ☐.The average rate of change of g(x) over 1≤x≤5 is ☐.The average rate of change of g(x) is ☐ times that of f(x)
-(Simplify your answers. Type integers or decimals.)
9514 1404 393
Answer:
3 times
Step-by-step explanation:
We observe that both functions are vertically scaled versions of the parent quadratic y = x^2. The ratio of scale factors is 2.7/0.9 = 3. That is, ...
g(x) = 3f(x)
This means that whatever vertical difference f(x) may show over the interval, g(x) will show 3 times that difference.
The average rate of change of g(x) is 3 times that of f(x).
1/9 divided by 8/7 =_ the lesson is called dividing fractions
Answer:
[tex] \frac{7}{72} [/tex]
Step-by-step explanation:
The question is :
[tex] \frac{1}{9} \div \frac{8}{7} [/tex]
We need to take the reciprocal which means invert the :
[tex] \frac{8}{7} [/tex]
So, it will be :
[tex] \frac{1}{9} \times \frac{7}{8} [/tex]
After that , do 1 × 7 on numerator and 9 × 8 on denominator....
After multiplication you'll get :
[tex] \frac{7}{72} [/tex]
1/9 divided by 8/7 is equal to 7/72.
To divide fractions, you can use the following rule: invert the second fraction and multiply it by the first fraction.
In this case, you have:
1/9 ÷ 8/7
To divide, we invert the second fraction:
1/9 × 7/8
Next, multiply the numerators (top numbers) together and the denominators (bottom numbers) together:
(1 × 7) / (9 × 8)
This simplifies to:
7/72
Therefore, 1/9 divided by 8/7 is equal to 7/72.

Reward: 30 pts
Answer: see below
Step-by-step explanation:
(i)
200/2 = 100
Find 100 on cumulative frequency and the correspinding time: 14 minutes. So the answer is 14 minutes.
(ii)
First, find the lower quartile —> 200/4 = 50
Upper quartile —> 200/(3/4) = 150
Find the difference: 150 - 50 = 100
So the interquartile range is 100

1/2/x=2/0.6 what is x
Answer:
x = 0.15
Step-by-step explanation:
We have two equivalent ratios: 0.5 (or 1/2)/x = 2/0.6. It looks like our Giant One is 4/4, since 0.5 * 4 = 2. We can divide 0.6 by 4 to find the value of x. 0.6/4 = 0.15, so x = 0.15.

Need help with number 4 and 5
Answer:
4. B
5. D
Step-by-step explanation:
4. Draw a line at angle to the line segment JK.
Then make three arcs on the new line using a compass without changing the setting.
Join the last arc to the endpoint of the line segment (in this case, K) and draw two parallel lines originating from the other two arcs.
5. Recall, there are two lines a and b
where x is the geometric mean.
Draw a line.
Label a point on the line (say, R)
Construct a segment (or arc) with endpoint R and length "a".
Construct a segment (or arc) with length "b" adjacent to the previous segment.
Label the endpoints (say, S and T). The line segment from point RS is "a" and that from point ST is "b".
Construct the perpendicular bisected of segment RT.
Label the midpoint of segment RT.
Using the midpoint as the center and half the length of RT as the radius, construct a semicircle.
At S, construct the perpendicular to segment RT. Label the intersection between the semicircle and perpendicular (say, Y)
SY is the geometric mean.
a/x = x/b is RS/SY = SY/ST

b) Is the sequence arithmetic, geometric or neither?
Answer:
a) 73, 82, 91
b) arithmetic
Step-by-step explanation:
a) We add 9 after each term, making the common difference 9.
As such, 64 + 9 = 73
73 + 9 = 82
82 + 9 = 91
b) This sequence is arithmetic because it has a common difference, if it had a common ratio, it would be geometric.

What is the equation in slope-intercept form for a line that passes through the points (-5, 5) and
(-45, 80)?
Answer:
y = -15/8x - 35/8
Step-by-step explanation:
Find the slope = [tex]\frac{change in y}{change in x}[/tex]
= [tex]\frac{80 - 5}{-45 - (-5}[/tex])
= [tex]\frac{75}{-40}[/tex]
= [tex]\frac{-15}{8}[/tex]
Find the y-intercept Use one point (-5, 5) and the slope [tex]\frac{-15}{8}[/tex]
y = mx + b
5 = -15/8 (-5) + b
5 = 75/8 + b
5 - 75/8 = b
-35/8 = b
Write the equation
y = -15/8x - 35/8

if i have a cupcake tree growing 4 cupcakes every 5 hours for ten hours how many cupcakes do i have
Answer: 8 cupcakes.
Step-by-step explanation:
4 cupcakes every 5 hours implies that 4 cupcakes grow in the span of 5 hours. if this is a ten hour period as the question states, then you have 8 cupcakes, as 4 cupcake batches grew twice in that 10 hour span.
how do you find the area of a circle
Answer:
A=πr2
Step-by-step explanation:
Area of a circle is found by the following formula-
Area of Circle = πr^2
Where -
π = pie, value of 3.14 or 22/7
r = radius of a circle
Example -
A circle has a radius of 10 cm. Find the area of the circle.
Solution -
Area of Circle = A=πr^2
A = 3.14*10^2
A= 314 cm
Note - Most preferably, 3.14 is the most common value used for pie. You can also use 22/7, and would end up with roughly the same answer, but it takes more time to solve with a fraction like 22/7.

The area of a shape is the amount of space it occupies.
The largest garden you could make is 49 square meters
