Answer:

69.9 (nice)

Step-by-step explanation:

To solve this, use the order of operations: PEMDAS (Parenthasis, exponents, Multiplication/Division, Addition/subtraction) In order.

1. Solve in the parenthasis, (2+3³).  3³ = 27, so 2+27 is 29. Plug in 29 to the equation: 5³-29×1.9

2. Next is exponents. 5³ has an exponent, which equals 125. Now you plug that into the equation to be 125-29×1.9

3. Now comes multiplication/division. In this case, it's multiplication. -29×1.9 . This equals -55.1, and you once again plug  this into the equation to simplify which gives you 125 - 55.1

4. Last in the order of PEMDAS is addition/subtraction. The final simplification of the equation is 125 - 55.1 which is subtraction and this equals 69.9 (nice)

So in conclusion, your answer is 69.9 (nice)

Answer:

1.5

Step-by-step explanation:

to find one hour you divide both answers by 1.5 giving you one hour and 1.5

1.5 yards did you mow in 1 hour when, You mowed 2.25 yards in 1.5 hours.

Division is the process of splitting a number or an amount into equal parts.

Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

You mowed 2.25 yards in 1.5 hours.

in 1 hours I mowed = 2.25/1.5

                               =1.5

Hence, 1.5 yards did you mow in 1 hour.

Answer:

6. Because to decrease = number × 100-% over 100(as a fraction)

which is =39.99 ×100-30% over 100

= 39.99 × 70/100

=27.993

After you take your answer from the decrease and subtract from the original price which is 39.99

39.99-27.993 *note the 39.99 has a zero at the end

the answer = 11.997 Rounded off it becomes 12

Answer:

[tex]2^1^5[/tex]

Step-by-step explanation:

Power rule: you multiply the exponent.

Think of it this way: [tex]X ^3 = X \times X \times X[/tex]. In this case, [tex]X = 2^5[/tex]

At this point our original number is [tex]2^5 \times 2^5 \times 2^5 = 2\times2\times2... \times 2[/tex]  with 15 2s

Which is, by definition, [tex]2^1^5[/tex]

The percentage of decrease is approximately 0.14%.

Step-by-step explanation:

35 - 5 = 30

What percentage is 5 of 35 (x/100 = is/of)

x/100 = 5/35 (cross multiply)

(5*100)/35 = 14.29%

The perimeter of the elliptical table is given by the path traced with the

string attached to the foci of the ellipse.

Reasons:

The shape of the table top = An ellipse

The dimensions of the plywood = 4 foot by 6 foot

Required:

The distance between the thumbtacks of the largest possible ellipse

Solution:

The major axis of the largest possible axis = 6 foot

The minor axis of the ellipse = 4 foot

[tex]The \ semi \ major \ axis, \ a = \dfrac{6}{2} = 3[/tex]

[tex]The \ semi \ minor \ axis, \ b = \dfrac{4}{2} = 2[/tex]

Which gives;

The focus, c² = a² - b²

Therefore;

c² = 3² - 2² = 5

c = √(5)

The distance between the two thumbtacks = c - (-c) = c + c = 2·c

Therefore;

The distance between the two thumbtacks = 2·√(5)

Answer:

z = 36

Step-by-step explanation:

1) Distribute

-18 = -3z + 18 + 2z

2) Combine like terms

-18 = -z + 18

3) Subtract 18 from both sides of the equation

-18 - 18 = -z + 18 - 18

4) Simplify

a. Subtract the numbers

-36 = -z + 18 - 18

b. Subtract the numbers

-36 = z

5) Divide both sides of the equation by the same term

-36/ - 1 = -z/-1

6) Simplify

a. Divide the numbers

36 = -z/-1

b. Cancel terms that are in both the numerator and denominator

36 = z

c. Move the variable to the left

z = 36

Answer: Percentage decrease = 20% × 7,720

New value = 7,720 - Percentage decreaseNew value =

7,720 - Percentage decrease =

7,720 - (20% × 7,720) =

7,720 - 20% × 7,720 =

(1 - 20%) × 7,720 =

(100% - 20%) × 7,720 =

80% × 7,720 =

Step-by-step explanation:

We have a sequence that meets the given criteria, and with that information, we want to get the sum of all the terms in the sequence.

We will see that the sum tends to infinity.

So we have 5 terms;

A, B, C, D, E.

We know that the sum of each term and its neighboring terms is 15 or 25.

then:

Now, we want to find the sum of all the terms in the sequence (not only the 5 given).

Then let's assume we write the sum of infinite terms as:

[tex]a_1 + a_2 + a_3 + a_4 + a_5 + a_6 + ...[/tex]

Now we group that sum in pairs of 3 consecutive terms, so we get:

[tex](a_1 + a_2 + a_3) + (a_4 + a_5 + a_6) + ...[/tex]

So we will have a sum of infinite of these, and each one of these is equal to 15 or 25 (both positive numbers). So when we sum that infinite times (even if we always have the smaller number, 15) the sum will tend to be infinite.

Then we have:

[tex](a_1 + a_2 + a_3) + (a_4 + a_5 + a_6) + ... \to \infty[/tex]

Answer:

(8 x c) - 4 = 6

or just simply

8c - 4 = 6

Step-by-step explanation:

Ok Madara, so four less means subtract by four, it saying that towards the product of 8 and unknown number,

so the product of 8 and an unknown number is

8 x unknown number

four less than that, is

(8 x c) - 4

ab=-7x3= -21

14- (-21)= 35

Answer:

a) 52

b) 21 + 6.25π

Step-by-step explanation:

Part (a)

the sides which we don't have:

(longer side): 7+6 = 13m

(shorter side): 13—8= 5m

So:

Perimeter = 2P = 13+5+7+8+6+13=52

Part (b)

perimeter of the half circle:

[tex]\pi \times {r}^{2} = \pi \times {2.5}^{2} = 6.25\pi[/tex]

So:

Perimeter = 2P = 2×8 + 5 + 6.25π = 21 + 6.25π
