5.7 is increased to 7.8
What is the percentage of increase?
Answer:
7.8%
Step-by-step explanation:
Answer:
The percentage of increase is 37%
Step-by-step explanation:
The way to find the percentage of increase is to divide The difference between the two numbers by the number before the increase
7.8 - 5.7 = 2.1
The difference between 7.8 and 5.7 is 2.1
So now we divided 2.1 by the number before the increase, in this case, 5.7
2.1 ÷ 5.7 = 0.3684
0.3684 rounded to the nearest hundredth is 0.37
Thus the percentage of increase is 37%

Meliyah is an administrative assistant. She earns a weekly salary of $412.00. She applied and was hired for an administrative specialist position. Meliyah’s annual salary in her new position will be $24,388.00. How much will Meliyah’s weekly salary be in her new position?
Answer:
[tex]Weekly\ Salary = \$469[/tex]
Step-by-step explanation:
Given
[tex]Current = \$412.00[/tex] --- weekly
[tex]NEw = \$24.388.00[/tex] --- annually
Required
Determine her new weekly salary
To do this, we simply divide her salary by 52 (the number of weeks).
So, we have:
[tex]Weekly\ Salary = \frac{\$24,388.00}{52}[/tex]
[tex]Weekly\ Salary = \$469[/tex]
Her weekly salary is $469

Construction of triangle with side measurement 2 inch, 3 inch, 5 inch is not possible.
What is triangle equality theorem?This theorem simply states that the sum of two sides of a triangle must be greater than the third side. If this is true for all three combinations, then you will have a valid triangle.
If triangle has the sides, a , b and c then
a + b > c
b + c > a
a + c > b
Given length of the sides,
a) Triangle made with sides having length 3 inch, 4 inch, 6 inch.
3 + 4 > 6 ; 4 + 6 > 3 ; 3 + 6 > 4
= 7 > 6 ; 10 > 3 ; 9 > 4
Triangle inequality theorem is satisfied, hence triangle construction is possible
b) Triangle made with sides having length 2 inch, 3 inch, 5 inch.
2 + 3 > 5 ; 3 + 5 > 2 ; 2 + 5 > 3
= 5 = 5 ; 8 > 3 ; 7 > 3
Triangle inequality theorem is not satisfied, hence triangle construction is not possible
a) Triangle made with sides having length 3 inch, 3 inch, 4 inch.
3 + 3 > 4 ; 3 + 4 > 3 ; 3 + 4 > 3
= 6 > 4 ; 7 > 3 ; 7 > 3
Triangle inequality theorem is satisfied, hence triangle construction is possible
a) Triangle made with sides having length 5 inch, 5 inch, 5 inch.
5 + 5 > 5 ; 5 + 5 > 5 ; 5 + 5 > 5
= 10 > 5 ; 10 > 5 ; 10 > 5
Triangle inequality theorem is satisfied, hence triangle construction is possible.
Hence, Triangle with side measurements of 2 inch , 3 inch , and 5 inch is not possible to construct.

What is x? and how did you get it?
Answer:
x = 16
Step-by-step explanation:
step 1 - 64 + 100 + x = 180 (all triangles equals 180)
step 2 - 164 + x = 180
step 3 - 164 + x = 180
-164. -164
step 4 - 180 - 164 = 16
step 5 - 100 + 64 + 16 = 180
(I do this part to double check my work)

ice cream is served for dessert if Gio serves himself and 3 friends half a cup of ice cream how many total pints did Gio and his friends eat?
Answer:
0.25 pints
Step-by-step explanation:
To find how many pints they ate, find the number of pints in half a cup.
In 1 cup, there are 0.5 pints.
This means in half a cup, there will be 0.25 pints.
So, Gio and his friends ate 0.25 pints

Fossils show that
insects were much larger around 300 million
years ago than they are today. The table at
the right shows some of the wing lengths
found in fossils. How much longer was the
wing length of the dragonfly than the wing
length of the fly?
Answer:
The wing of the dragonfly was 9.65 cm longer than that of the fly, 102% larger in percentage terms.
Step-by-step explanation:
Since the length of the wing of the old dragonfly was 19.5 cm, while the length of the wing of a common fly is 9.85 cm, to determine how long the dragonfly's wing was compared to that of the fly, the following must be done calculations:
19.5 - 9.85 = X
9.65 = X
Thus, the wing of the dragonfly was 9.65 cm longer than that of the fly. In turn, in terms of percentages, the result is the following:
9.65 = 100
19.5 = X
19.5 x 100 / 9.65 = X
1950 / 9.65 = X
202 = X
Thus, in percentage terms, the dragonfly's wing was 102% larger than that of the current fly.

if right answer good review
Answer:
Top left: a is negative and p is positive
Step-by-step explanation:
The formula y = ax + p is referring to the formula y = mx + b where m is the slope and b is the y-intercept.
Since the line is going down, the slope is negative-- a is negative.
Since the line crosses the y-axis above the origin, the y-intercept is positive-- p is positive.
Answer:
a is negative and p is positive
Step-by-step explanation:
The equation y = ax + p is written in slope-intercept form, where a is the slope and p is the y-intercept.
When a slope is negative, the line goes down the further right it goes.
The line on the graph lowers as it moves right, which means that the slope(a) is negative.
The line intercepts the y-axis above the origin, which means that it must be positive.

form a triangle
Answer:
Step-by-step explanation:
No. If two sides are 5cm the third side must be less than 2(5)=10cm
Answer: No, a triangle cannot be formed with these side lengths.
=========================================================
Explanation:
Recall that the triangle inequality theorem says that for a triangle to be possible, the sum of any two sides must be larger than the third side.
With these given side lengths, we can see that 5+5 = 10 is not larger than 20, so a triangle is not possible here. I recommend you try it out with 3 slips of paper of these lengths. You should find that the two 5 cm sides are too short to be able to connect to the 20 cm side properly.

Which is greater, 0.28 or 0.205? Explain how you know.
Answer:
Step-by-step explanation:
0.28 is roughly the same as 0.280, which has 3 significant digits (same as 0.205 has 3 significant digits). It's easier when we compare numbers having the same number of decimal places.
Comparing 0.280 to 0.205, we see that the hundredths place of 0.280 (which is 8) is greater than the hundredths place of 0.205 (which is 0). Thus 0.28 is greateer than 0.205.

Find the circumference of a circle that has a diameter of 5 inches. Use 22/7 for pi.
15 in.
22/35 in.
15 3/7 in.
15 5/7 in.
Answer:
step 1. The circumference (c) of a circle is equal to the diameter of a circle x pi. c = d(pi) = 5pi
step 2. c = 5pi = 5(22/7) = 110/7 = 15 5/7.
