5.7 is increased to 7.8
What is the percentage of increase?

Answers

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%

Answer:

Step-by-step explanation:

Of the ten socks,

10/11 chance of wearing white socks

form a triangle

Answers

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.

What is x? and how did you get it?

Answers

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)

step 6 - x = 16

Answer:

x = 48

Step-by-step explanation:

The ratio:

x/64 = (100 - 64)/xx² = 64*36x = 48

Answer:

C. y = 2x + 8

Step-by-step explanation:

✔️First, find the slope of the line that goes through points (-2, 4) and (6, 20):

Slope (m) = ∆y/∆x = (20 - 4) / (6 - (-2))

Slope (m) = 16/8

m = 2

✔️Find the y-intercept (b):

To do this, substitute (x, y) = (6, 20) and m = 2 into y = mx + b

Thus:

20 = 2(6) + b

20 = 12 + b

20 - 12 = b

8 = b

b = 8

✔️Write the equation by substituting m = 2 and b = 8 into y = mx + b

Thus:

y = 2x + 8

10 Six years ago Jon was one-sixth the age of his mother
and in four years time his age doubled and increased
by 10 will match his mother's age. How old is Jon
now?

Answers

Answer:

Jon is 11 years old

Step-by-step explanation:

We write the following equations describing the sentences of the problem, using the letter M to represent Jon's mom's current age, and j to represent his current age.

First sentence: "Six years ago Jon was one-sixth the age of his mother."

translates into:

J - 6 = (M - 6) / 6

Second sentence: "in four years time his age doubled and increased

by 10 will match his mother's age."

2 * (J + 4) + 10 = M + 4 which removing parentheses gives: 2 J + 18 = M + 4

We solve for "M" in the first equation

6 (J - 6) = M - 6

6 J - 36 = M - 6

M = 6 J - 30

and now use this result to substitute for M in the second equation

2 J + 18 = (6 J - 30) + 4

and work on solving for J

2 J + 18 = 6 J - 30 + 4

18 + 26 = 6 J - 2 J

44 = 4 J

J = 44 / 4

J = 11

a) Let P(t) be written as
P(t) = a cos[b(t - d)] + c
The minimum Pmin and the maximum Pmax of P(t) are given.
Pmin = 4
Pmax = 20
c = (Pmax + Pmin) / 2 = (20 + 4) / 2 = 12
|a| = (Pmax - Pmin) / 2 = (20 - 4) / 2 = 8
We now need to find the number of days t after January 1st at which P(t) is maximum by counting the days of the months from January to May and adding 21 days in June.
t = 31 + 28 + 31 + 30 + 31 + 21 = 172
We now use the period to find b (b > 0) as follows
period = 365 = 2π / b
hence b = 2π / 365
A cosine function without shift has a maximum at t = 0. P(t) has a maximum at t = 172. We can model P(t) by a cos(x) function shifted by 172 to the right as follows:
P(t) = 8 cos[(2π / 365)(t - 172)] + 12
check that P(t) is maximum at t = 172: P(172) = 8 cos[(2π / 365)(172 - 172)] + 12 = 8 cos[(0)] + 12 = 20
b) The graph of P(t) is shown below.

Which is greater, 0.28 or 0.205? Explain how you know.

Answers

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.

a triangle with side measurements of 2, 3, and 5 inches
a triangle with side measurements of 3, 3, and 4 inches
a triangle with side measurements of 5, 5, and 5 inches.

Answers

Answer:

a triangle with side measurements of 5, 5, and 5 inches

Step-by-step explanation:

I took the test.

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.
