Answer:

13.

Step-by-step explanation:

12.9 is closer to 13.

square root 167 is 12.923, this rounded to the nearest unit is 13

Let the two numbers be 3x and 4x

sum =3x + 4x = 7x

7x = 133

x= 19

the numbers are :

3(19) = 57

4(19) = 76

Answer:

57 and 76

Step-by-step explanation:

Given the ratios are 3 : 4 = 3x : 4x, then

3x + 4x = 133

7x = 133 ( divide both sides by 7 )

x = 19

The numbers are

3 × 19 = 57 and 4 × 19 = 76

Answer:

[tex]x=-7[/tex]

Step-by-step explanation:

We can write them both like functions like this

[tex]A=5x-4[/tex]

[tex]B=3x+8[/tex]

Where

x=input

A=Output A

B=Output B

We want the output of A 3 times the output of B this can be written like this:

[tex]A=3B[/tex]

we replace with the functions

[tex]5x-4=3(3x+8)[/tex]

we solve for x

[tex]5x-4=9x+24\\5x-9x=24+4\\-4x=28\\x=\frac{28}{-4}\\x=-7[/tex]

The output that makes the out put of A 3 times teh output of B is [tex]-7[/tex]

To find the input that makes the output of A three times the output of B, solve the equation 3(B's output) = A's output by plugging in the values for each machine. The input that satisfies this equation is X = -7.

To find the input that makes the output of A three times the output of B, we need to solve the equation 3(B's output) = A's output. Let's plug in the given values into the machines to solve for X:

Now we can set up the equation and solve for X:

3(3X + 8) = 5X - 4

9X + 24 = 5X - 4

9X - 5X = -4 - 24

4X = -28

X = -7

Therefore, the input that makes the output of A three times the output of B is X = -7.

ANSWER

No solution

EXPLANATION

The first equation is

and the second equation is

[tex]y = - 2x - 1[/tex]

We equate the two equations to obtain;

[tex] {x}^{2} - 2x = - 2x - 1[/tex]

This implies that

[tex] {x}^{2} = - 2x + 2x - 1[/tex]

[tex] {x}^{2} = - 1[/tex]

There is no real number whose square is -1.

Therefore, the equation has no solution.

Answer:

Step-by-step explanation:

Volume of a rectangular prism is V= LWH,

we are given V = 528, L = 12, and H = 5 1/2.  Plug  them in and find W..

First convert 5 1/2 to an improper fraction

5 1/2 becomes 11/2

   528 = (12)(11/2)W

      528 = (132/2)W

        528 = 66W

            8 = W  (divide both sides by 66)

This answer explains how to calculate the number of different sizes of bags that can be made from a specific amount of nuts, considering whole numbers of bags.

a. To determine how many 1-pound bags can be made from a 27-pound bag of nuts, divide 27 by 1, which gives you 27 bags.

b. For 2-pound bags, divide 27 by 2 to get 13.5 bags. Since you can't have half a bag, you can make only 13 bags.

c. To find the number of 3/4-pound bags from a 2.5-pound bag, divide 2.5 by 0.75, which equals 3.33 bags, but you can make only 3 bags because you can't have a fraction of a bag.

Answer:

-135

Step-by-step explanation:

The summation notation of 10∑n=2 -2n-3.

We can find the values by substituting n into -2n-3.

Let's begin where n = 2

-2(2) - 3 = -7

-2(3) - 3 = -9

-2(4) - 3 = -11

-2(5) - 3 = -13

-2(6) - 3 = -15

-2(7) - 3 = -17

-2(8) - 3 = -19

-2(9) - 3 = -21

-2(10) - 3 = -23

This gives us:

-7 + -9 + -11 + -13 + -15 + -17 + -19 + -21 + -23 = -135

The question is likely related to evaluating a summation sequence using sigma notation, but the specifics are unclear due to possible typos. The correct approach would be to substitute values of n into the given expression and sum the results, but the question needs clarification.

The student's question appears to involve the concept of a summation, indicated by the sigma notation (Σ), which is a common topic in high school mathematics, particularly in algebra, pre-calculus, or AP statistics. However, the question, as written, is incomplete or contains typos that make it unclear. The phrase '10 sigma n=2 -2n-3' is not sufficient to provide a full context for an evaluation. It is likely that the student is asking to evaluate a summation formula that starts at n=2, but the upper limit of the summation (10) and the actual expression to be summed (-2n-3) are not clearly linked.

If the student intended to ask for the evaluation of the summation of the expression -2n-3 from n=2 to n=10, then we would calculate the sum as follows:

However, without clarification from the student, we cannot proceed with certainty. It is important to understand the exact parameters of the summation when dealing with sigma notation and summation formulas.

Answer:

The area of the plate is 21 inches

Step-by-step explanation:

* Lets revise some rules of a circle

- The circumference of a circle = 2πr , where r is the radius of it

- The area of the circle = πr²

* Lets solve the problem

∵ A circular plate has circumference 16.3 inches

∵ The circumference = 2πr

∵ π = 3.14

- Lets find the radius of the plate

∵ 16.3 = 2(3.14)r

∴ 16.3 = 6.28r

- Divide both sides by 6.28

∴ r = 16.3/6.28 = 2.5955 ≅ 2.6

∴ The radius of the plate is 2.6 inches

* Lets find the area of the plate

∵ The area = πr²

∵ π = 3.14

∵ 4 = 2.6

∴ The area = 3.14(2.6)² = 21.22 ≅ 21

* The area of the plate is 21 inches

To find the area of a circle with a circumference of 16.3 inches using 3.14 for pi, you first calculate the radius and then use the formula A = πr² to get the area, which when rounded to the nearest whole number is approximately 21 inches².

To calculate the area of a circular plate when given its circumference, we first need to find the radius of the circle. We use the formula for the circumference of a circle, C = 2πr, where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius. The student has provided the circumference as 16.3 inches, so we solve for r:

C = 2πr

16.3 inches = 2 × 3.14 × r

16.3 inches / (2 × 3.14) = r

16.3 inches / 6.28 = r

2.597 inches = r

Now that we have the radius, we can use the area formula for a circle, A = πr². Plugging in our radius we get:

A = 3.14 × (2.597 inches)²

A = 3.14 × 6.7473 inches²

A = 21.205 inches²

Rounding to the nearest whole number:

A ≈ 21 inches²

Answer:

1 and 8 are the ones you should choose.

Step-by-step explanation:

Answer: ∠1 and ∠8

Step-by-step explanation:

Given : Line b is parallel to line c .

In the given figure , a traversal line is passing through line b and c.

∠2=120°

Then , ∠1 +∠2=180°   [linear pair]

⇒ ∠1=180°-120°=60°

Now, ∠4 and ∠1 are vertical angles.

Since vertical angles are congruent.

∴ we have , ∠4 ≅ ∠1 =60°

Also, ∠4 and ∠8 are corresponding angles and corresponding angles are congruent.

∴ we have , ∠4 ≅ 8 =60°

∠2 cannot be congruent to ∠4, since both have different measures

∠7 cannot be congruent to ∠4, since ∠7 is congruent to ∠2 (Alternate exterior angles)

Answer:

x = - 3[tex]\sqrt{2}[/tex], x = [tex]\sqrt{2}[/tex]

Step-by-step explanation:

Given

x² + 2[tex]\sqrt{2}[/tex] x - 6

To calculate the zeros equate to zero

x² + 2[tex]\sqrt{2}[/tex] x - 6 = 0 ( add 6 to both sides )

x² + 2[tex]\sqrt{2}[/tex] x = 6

One way is to use the completing the square method

add ( half the coefficient of the x- term )² to both sides

x² + 2[tex]\sqrt{2}[/tex] x + ([tex]\sqrt{2}[/tex])² = 6 + ([tex]\sqrt{2}[/tex])²

x² + 2[tex]\sqrt{2}[/tex] x + 2 = 6 + 2

(x + [tex]\sqrt{2}[/tex] )² = 8

Take the square root of both sides

x + [tex]\sqrt{2}[/tex] = ± [tex]\sqrt{8}[/tex] = ± 2[tex]\sqrt{2}[/tex]

subtract [tex]\sqrt{2}[/tex] from both sides

x = - [tex]\sqrt{2}[/tex] ± 2[tex]\sqrt{2}[/tex]

x = - [tex]\sqrt{2}[/tex] - 2[tex]\sqrt{2}[/tex] = - 3[tex]\sqrt{2}[/tex], or

x = - [tex]\sqrt{2}[/tex] + 2[tex]\sqrt{2}[/tex] = [tex]\sqrt{2}[/tex]

Step-by-step explanation:

5000(1+(.04/4))^4

The total amount accrued, principal plus interest, with compound interest on a principal of $5,000.00 at a rate of 4% per year compounded 1 times per year over 3 years is $5,624.32.

Given Data

A = P + I where

P (principal) = $5,000.00

I (interest) = $624.32

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 4/100

r = 0.04 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 5,000.00(1 + 0.04/1)^(1)(3)
