Answer:

1/4x=8 which also equals 32

Step-by-step explanation:

12-4=8

5/8-3/8=2/8=1/4

1/4x=8   then you would multiple each side by 4 to cancel out and 4*8=32

Answer: 18

Answer:

39.6 cm

Step-by-step explanation:

Applying

s = 2πrθ/360................ Equation 1

Where s = length of an arc or distance traveled by the minutes hand of the clock during the 42 munites, r = length of the minutes hand of the clock, θ = Angle traveled by the minute hand of the clock for every 42 minutes

From the question,

Given: r = 9 cm, θ = 252°

Constant: π = 22/7 = 3.14

Substitute these values into equation 1

s = (2×3.14×9×252)/360

s = 39.564

s = 39.6 cm

Answer:

67.83 feet

Step-by-step explanation:

Let h be the height of the tower and d be the distance from the point on the ground to the tower at an angle of elevation of 25° 51' from the tower. The line of sight of this point from the top of the tower, h and d form a right-angled triangle with the line of sight at an angle of elevation of 25° 51' being the hypotenuse side.

Using trigonometric ratios,

tan25° 51' = h/d

h = dtan25° 51'

We convert to degrees 25° 51'

25° 51' = 25° + 51' × 1°/60' = 25° + 0.85° = 25.85°

So, h = dtan25.85°

d = 140 feet

h = 140tan25.85°

h = 140 × 0.4845

h = 67.83 feet

Answer:

C- Every term in pattern B is 5 times the corresponding term in pattern A.

Step-by-step explanation:

First, to see the pattern you should divide the terms of A with the corresponding term in B:

In the options, there is a choice that has the number 1/5, but... Read carefully, it says that EVERY TERM OF B IS 1/5 TIMES THE IT'S THE CORRESPONDING TERM IN A.

The one that we found as 1/5 is the opposite, every term of A is 1/5 times the corresponding term in B.

To find what is the true statement, there are different ways to follow, but the simplest could be dividing the B terms into their corresponding A term:

The correct answer will be that every term in pattern B is 5 times the corresponding term in pattern A.

Hope it helps!!

Given:

The expression is:

[tex]a\times a\times a\times c\times c\times c\times c\times 5\times 5\times 5\times 5[/tex]

To find:

The index form of a the given expression.

Solution:

Index form is the exponent form.

We have,

[tex]a\times a\times a\times c\times c\times c\times c\times 5\times 5\times 5\times 5[/tex]

Here, a is multiplied with itself 3 times, c is multiplied with itself 4 times and 5 is with itself 4 times. So, the power of a, c and 5 must be 3, 4 and 4 respectively.

[tex]a\times a\times a\times c\times c\times c\times c\times 5\times 5\times 5\times 5=a^3c^45^4[/tex]

Therefore, the index form of the given expression is [tex]a^3c^45^4[/tex].

Answer:

B. 45

Step-by-step explanation:

Just a pure guess. I got roasted a lot of times :( so I just guessed

126 groups can be made.

Combinations are selections made by taking some or all of a number of objects, irrespective of their arrangements. The number of combinations of n different things taken r at a time, denoted by

n^C_r = n!/ r!( n-r)!

Suppose we have a set of 6 letters { A,B,C,D,E,F}. In how many ways can we select a group of 3 letters from this set? Suppose we find the number of arrangements of 3 letters possible from those 6 letters. That number would be 6P3

. Consider the permutations that contain the letters A, B, and C. These are 3! = 6 ways, namely ABC, ACB, BAC, BCA, CAB, and CBA.

We calculate combinations using the combinations formula, and by using factorials and in terms of permutations. In general, suppose we have n things available to us, and we want to find the number of ways in which we can select r things out of these n things. We first find the number of all the permutations of these n things taken r at a time. That number would be

nPr.

Given:

n= 9, r=5

n^C_r= 9!/ 5! * 4!

= 9*8*7*6/ 4*3*2

=126

Hence, there are 126 ways.

Step-by-step explanation:

Answer:

No he is not correct.

He said the end of the monthly amount was 250% of his original amount which is true. Then the correct option is A.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Andy has been saving his pocket money. He began the month with $44 and ended with $110.

Then the percentage is given as,

P = [(110 / 44] x 100

P = 2.5 x 100

P = 250%

He said the end of the monthly amount was 250% of his original amount which is true. Then the correct option is A.

Step-by-step explanation:

Answer:

The value of S4 for infinity sigma n=1 10(0.2)^n-1 is B. 12.48

Step-by-step explanation:

summation is the addition of a sequence of any kind of numbers

Here we need to find the summation of first four terms.

so ,

S₄ = 10 ×[tex]( 0. 2 )^{4-1}[/tex]  = 0.08

S₃ = 10 × [tex]( 0.2 )^{3-1}[/tex] = 0.4

S₂ = 10 ×  [tex]( 0.2 )^{2-1}[/tex] = 2

S₁ = 10  ×  [tex]( 0.2 )^{1-1}[/tex] = 10

Thus, The Value of Summation = S₄ + S₃ + S₂ + S₁ = 12.48
