Answer:

4, Third option

Step-by-step explanation:

When you get 9^8 the answer is 43046721. So when raising a power to a power, the products should equal 8. Using simple math, we can determine that 4x2=8. To check our work you can calculate (9^2)^4, which equals 43046721. Now we can now for sure that this answer is correct. Hope this helps!

Answer:

A ten digit number without any equal digits is a permutation of 0,1,2,3,4,5,6,7,8,9.

Assuming the first digit cannot be zero, there are 9×9! such permutations.

In total there are 9×109 ten digit numbers so you can easily calculate the probability.

Answer:

(14/3, 7/3)

Step-by-step explanation:

8-3=5, and 5/3+3=14/3.

5--3=8, and 8/3+5=7/3.

This has a ratio of 1:2 because the length is divided into three and 1 is separate from the other two.

Answer:

[tex]\sf a. \quad \dfrac{21}{10+x}+\dfrac{21}{10-x}=5[/tex]

Step-by-step explanation:

Formula for calculating speed:

[tex]\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]

Therefore:

[tex]\boxed{\sf Time=\dfrac{Distance}{Speed}}[/tex]

Given values:

If the boat is traveling downstream, the current (x mph) will be pushing the boat faster, and so the boat's speed will increase by x mph.

Therefore, the expression for the time it takes for the boat to travel downstream is:

[tex]\sf Time\:(downstream)=\dfrac{21}{10+x}[/tex]

If the boat is traveling upstream, the current (x mph) will be pushing against the boat and so the boat's speed will decrease by x mph.

Therefore, the expression for the time it takes for the boat to travel upstream is:

[tex]\sf Time\:(upstream)=\dfrac{21}{10-x}[/tex]

Therefore, if the total time it takes to travel downstream and upstream is 5 hours:

[tex]\implies \sf \dfrac{21}{10+x}+\dfrac{21}{10-x}=5[/tex]

To solve for x:

[tex]\implies \sf \dfrac{21}{10+x}+\dfrac{21}{10-x}=5[/tex]

[tex]\implies \sf \dfrac{21(10-x)}{(10+x)(10-x)}+\dfrac{21(10+x)}{(10-x)(10+x)}=5[/tex]

[tex]\implies \sf \dfrac{21(10-x)+21(10+x)}{(10+x)(10-x)}=5[/tex]

[tex]\implies \sf21(10-x)+21(10+x)=5(10+x)(10-x)[/tex]

[tex]\implies \sf 210-21x+210+21x=5(100-10x+10x-x^2)[/tex]

[tex]\implies \sf 420=500-5x^2[/tex]

[tex]\implies \sf 5x^2=80[/tex]

[tex]\implies \sf x^2=16[/tex]

[tex]\implies \sf x=\pm4[/tex]

Therefore, the rate of the current is 4 mph.

Answer:

Option C; 26cm by 14 cm

Step-by-step explanation:

Answer: There is 5 non blue sock in Josh's drawer

Step-by-step explanation:

The denominator shows the total of nonblue and blue socks. So there are 7 non-blue and blue socks in the drawer after he removes 3 non blue socks.To find how many non-blue where in the drawer originally you need to find how many non blue are in the draw after removing the three. So you subtract 7 from 5 which gives you 2. So there are 2 non-blue socks in the drawer after removing the three. Now you need to find how many non-blue were there before he removed the three. So add the 3 non blue socks that he removed to the two that were there after which gives you five.

Answer: 62.8in

Step-by-step explanation:

The formula for circumference is C=2πr. Put the values of 10 in for r and 3.14 in for pi, and you get an equation that looks like C=2(3.14)(10). Solving this equation gets you 62.8.

Answer:

62.8

Step-by-step explanation:

Circumference=2rpi

c=2*10*pi

c=20*pi

c=20*3.14

c=62.8

To figure out the average of Michael and Melissa we must add up all their test scores and divide the by 7; which is the number of tests they took.

Michael:

(80+76+73+70+40+25+10)/7

Melissa:

(88+83+75+70+60+65+62)/7

Michael's average is 53.4

Melissa's average is 71.9

So Melissa is earning a C in Latin.

The domain of the notation [tex]s(x) = \sum\limits^{\infty}_{n=1} n^{-x}[/tex] is the set of all real values

The sum notation is given as:

[tex]s(x) = \sum\limits^{\infty}_{n=1} n^{-x}[/tex]

From the above notation, the smallest value of n is 1.

This means that the variable x can take any real value as it value

Hence, the domain of the notation [tex]s(x) = \sum\limits^{\infty}_{n=1} n^{-x}[/tex] is the set of all real values

Answer: Should be around $23,000

Step-by-step explanation:

39.8% of 61463

Answer:

first the triangle

t area=b x h ÷2

=(5ft x 10.5ft)÷2

=26.25ft sq unit

second the rectangle

r area=L × b

=9ft × 7.5ft

=67.5ft sq unit

last the triangle

t area= b×h÷2

=(9ft×4.5ft)÷2

=20.25ft sq unit

Answer:

110.25 ft^2

Step-by-step explanation:

We can find the area of the figure by adding up the areas of three different shapes.

1) The right triangle

The formula for finding the area of a right triangle is: Base x Height x 1/2

The base in the right triable is 5 and the height is 9.

--> 5 x 9 x 1/2

--> 45/2

--> 22.5

2) The rectangle

The formula for finding the area of a rectangle is: Base x Height

The base is 7.5 and the height is 9.

--> 7.5 x 9

--> 67.5

3) The Isosceles Triangle (On the very right)

The formula for finding the area of a right triangle is: Base x Height x 1/2

The base of the triangle is 9, and the height is 4.5.

--> 9 x 4.5 x 1/2

--> 40.5/2

--> 20.25

Now that we know the areas of separate shapes, all we need to do is add them up!

22.5 + 67.5 + 20.25

= 110.25.

The area of the figure is 110.25 ft^2

4. 1, 0

The value of a and b from the coordinates are 3 and 5 respectively

The formula for finding the midpoint of two coordinates is expressed as;

M(x, y) = {x1+x2/2, y1+y1/2}

Given the following coordinates

M(a, 4)

A(1,3)

B(5,b)

Using the formula

a = 1+5/2

a = 6/2

a = 3

Similarly

4 = 3+b/2

8 = 3+b

b = 8-3

b = 5

Hence the value of a and b from the coordinates are 3 and 5 respectively
