Answer:

A. 243/469

Step-by-step explanation:

Looking at the terms here, it seems that the this powers of 3 divided by 469.

3 is 3¹. 9 is 3². 27 is 3³. 81 is 3⁴.

Knowing that, then 3⁵/469 is the next term. 3⁵ is 243, so the next term is 243/469, which is A.

Answer:

(x+8)= 10 so 8 subtracted from 8 is zero and 8 subtracted from 10 is 2 so the

the answer is 2

Answer:

Step-by-step explanation:

Unless we set x^2 + 8x + 15 equal to zero, we don't have an equation to be solved.  I will assume that the problem is actually x^2 + 8x + 15 = 0.

The coefficients of this quadratic are {1, 8, 15}, and so the "discriminant" b^2 - 4ac is (8)^2 - 4(1)(15), or 4.  Because the discriminant is positive, we know that there are two real, unequal roots.

Continuing with the quadratic formula and knowing that the discriminant is 4, we get:

      -8 ± √4           -8 ± 2

x = ---------------- = --------------- , or x = -2 ± 1:  x = -3 and x = -5

          2                       2

Answer:

The answer is four since the probability is 1/4 in fraction form

Step-by-step explanation:

31.5$

102ml

50 hamburgers

Step 1: Our output value is 700.

Step 2: We represent the unknown value with $x$x​.

Step 3: From step 1 above,$700=100\%$700=100%​.

Step 4: Similarly, $x=42\%$x=42%​.

Step 5: This results in a pair of simple equations:

$700=100\%(1)$700=100%(1)​.

$x=42\%(2)$x=42%(2)​.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{700}{x}=\frac{100\%}{42\%}$

700

x​=

100%

42%​​

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{700}=\frac{42}{100}$

x

700​=

42

100​​

Therefore, 42% of 700 is 294.

Answer:

- The neighbor that has the most amount of fence to put up is: Neighbor A.

- The neighbor that has the least amount of fence to put up is: Neighbor C.

Step-by-step explanation:

To calculate the amount of fence that Neighbor A has to put up, you need to add the following distances:

Convert yards to feet (Remember that :

To calculate the amount of fence that Neighbor B has to put up, you need to use the formula for calculate the circumference of a circle:

Where r is the radius.

In this case, the radius is:

Substituting, you get:

To calculate the amount of fence that Neighbor C has to put up, you need to add the following distances:

Therefore, the neighbor that has the most amount of fence to put up is: Neighbor A.

The neighbor that has the least amount of fence to put up is: Neighbor C.

a) 5y - 25

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

The grade percentage of Marco is 50%.

A percent is a dimensionless number, meaning that it has no units of measurement, since it represents a part of whatever whole is being measured.

Given that, Marco got 15 questions wrong on his 30-question test.

We need to find his grade as a percent,

So,

Since he got 15 answers wrong,

Therefore, his correct answers = 30-15.

That mean his grade in marks = 15

Now, his grade in percent = 15/30 x 100 = 50%

Hence the grade percentage of Marco is 50%.

Answer:

d) [tex](9*3/4)+y[/tex]

Step-by-step explanation:

b) [tex]9+y*(3/4)[/tex]

This expression is not equivalent, as the original expression, [tex]y+9*\frac{3}{4}[/tex] , has 9 multiplied to [tex]\frac{3}{4}[/tex] instead of y. You can interchange values like this when it comes to addition, but not multiplication.

c) [tex](y+9)(3/4)[/tex]

This expression is also not equivalent. After opening up the parentheses, it would again result in y being multiplied to [tex]\frac{3}{4}[/tex].

[tex](y+9)(3/4)\\= y(3/4)+9(3/4)[/tex]

d) [tex](9*3/4)+y[/tex]

This expression is equivalent, as 9 and [tex]\frac{3}{4}[/tex] are still being multiplied together and y is added to the product. We can actually rearrange this to look like the original expression:

[tex](9*3/4)+y\\=y+(9*3/4)\\=y+(9*\frac{3}{4} )\\=y+9*\frac{3}{4}[/tex]

Answer:1/343

Step-by-step explanation:

you can use the exponent rule so you would be left with (1/7)^9-6 which would simplify to (1/7)^3. The if you not using a calulater, you can take 1/7 and individually cube the numbers to find the final answer. So 1^3/7^3. This would simplify to 1/7^3. 7^3 is 343. This leaves you with the final answer.

Answer :

$38 + $2(n) where n is the no. of cars.

Step-by-step explanation:

He earns $38 daily which is fixed and additional $2 wage depends on the no. of cars which means no. of cars will determine how many $2's he earns.

25 cars = $38 + $2 (25) = $88

30 cars = $38 + $2 (30) = $98

35 cars = $38 + $2 (35) = $108

40 cars = $38 + $2 (40) = $118

Answer:

96

Step-by-step explanation:

The volume of the square pyramid is 96 cm³.

You can locate the extent of a normal square pyramid with the use of the volume formula= base location² × height / 3. Take be aware that the bottom vicinity equals the square of the pyramid's base side period. However, the peak is the perpendicular distance between the pyramid's base and the pyramid's vertex.

By using the given formula, we get

V= a² h/3

=6² * 8 / 3 = 96

The answer is 96 cm³.

The volume of a pyramid is found using the formula V = (1/3) B*h, where 'B' is the base area and 'h' is the height of the pyramid.
