Answers to both the subparts using mathematical operations are shown:

(A) Rate of the car in miles/min: 0.95 miles/min

(B) Distance traveled in 5 min: 4.8 miles

Calculating a value using operands and a math operator is referred to as performing a mathematical "operation."

The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers.

PEMDAS stands for Parentheses, Exponents, Multiplication, Division, and Addition Subtraction (from left to right).

So, we know that the rate of the car is 57 miles/hour.

(A) Car rate in miles/min

We know that 1 hour has 60 minutes. Then,

57/60

0.95 miles/min

(B) Distance traveled in 5 min:

0.95 * 5

4.75

Rounding off: 4.8 miles

Therefore, answers to both the subparts using mathematical operations are shown:

Perimeter is 30.A triangle's perimeter is measured in the same unit as its side lengths.

Additionally, a triangle's perimeter and side lengths are measured in the same unit.If the lengths of its sides are measured in a different unit, first convert them to that unit.

Perimeter of a triangle = sum of all three sides.

Since it's equilateral, just solve for x with any of the 2 sides being equal

2x + 4 = 3x + 1

Subtract 1 from both sides

2x + 3 = 3x

Subtract 2x from both sides

Answer:

ANS:- 67

Step-by-step explanation:

d = a2 - a1

a2 = 307, a1 = 313

d = 307 -313 = -6

an = a1 + (n - 1)d

a1 = 313, n = 42, d = -6

a42 = 313 + (42 -1)(-6)

a42 = 313 + (41)(-6)

a42 = 313 - 246

The estimated value was 9,000,000,000 strawberries sold this year than last year.

As per the given information, the required solution would be as:

We must calculate the most accurate estimate of the number of strawberries sold this year and the previous year.

Rounding up to the closest full number is the best approximation.

This year, 7,234,267,990 strawberries were purchased.

Last year, 2,000,900,999 strawberries were purchased.

Based on the above value, the estimated number of strawberries sold this year and the previous year is:

= 7,000,000,000 + 2,000,000,000

= 9,000,000,000

Thus, the estimated value was 9,000,000,000 strawberries sold this year than last year.

Step-by-step explanation:

Answer: 63

Step-by-step explanation:

You can put this solution on YOUR website! Hi there, 2/3 = 42. Multiply 42 by 3 = 126. Divide 126 by 2 = 63. The lady's age. 63yrs old. Proof: 2/3 x 63

Answer:

63

Step-by-step explanation:

42 / 2 = 21

21 * 3 = 63

If 42 is two thirds, then one third is 21 because (2/3) / 2 = 1/3.

If 21 is one third, then the whole is 63 because (1/3) * 3 = 1.

The mean , standard deviation, and the variance of each binomial experiment using given probability and sample of restaurant owners surveyed is equal to 54.52 , 1.808, 3.2712 respectively.

As given in the question,

Let success be defined by health department inspection is passed by restaurant

Probability of success rate 'p' = 0.94

Value of ' 1 - p ' = 1 - 0.94

                       = 0.06

Number of owners of restaurant which are surveyed 'n' = 58

For the given binomial experiments calculation of the following distributions are:

Mean 'μ' = np

            = 58 × 0.94

            = 54.52

Standard deviation 'σ' = √ np (1 - p)

      = √ 58 × 0.94 × 0.06

                                  = √3.2712

                                  = 1.808

Variance 'σ²' =  np( 1 - p )

                   = 58 × 0.94 × 0.06

                  = 3.2712

Therefore, the mean , standard deviation , and the variance from the given probability and sample size is equal to 54.52 , 1.808, 3.2712 respectively.

Here, we have

Given

The perpendicular bisectors of its sides are TS, US, and VS. They meet at a single point S.

VS 80, YZ=86, and ZS=116 and we have to find XS, UZ, and VY.

TS, US, and VS are perpendicular bisectors

So, XV = VY, YU = UZ, XT = TZ

Then, ΔYST ≅ ΔZST

ΔYSV ≅ ΔXSV

ΔYUS ≅ ΔZUS

So, XS = ZS = 116

UZ = 1/2YZ = 1/2×86 = 43

VY = VX

VX² + VS² = XS²

VX = √XS² -VS²

VX = √116² - 80²

VX = 84

Answer:

10, 35, 135, 410, 1235, ...

Step-by-step explanation:

a(1) = 10

a(n) = 3 * a(n-1) + 5

This recursive sequence starts with the initial value of a(1) = 10, and each subsequent term is calculated by applying the formula a(n) = 3 * a(n-1) + 5. The resulting sequence would be:

a(1) = 10

a(2) = 3 * a(1) + 5 = 3 * 10 + 5 = 35

a(3) = 3 * a(2) + 5 = 3 * 35 + 5 = 135

a(4) = 3 * a(3) + 5 = 3 * 135 + 5 = 410

a(5) = 3 * a(4) + 5 = 3 * 410 + 5 = 1235

And so on. This recursive sequence generates the following sequence: 10, 35, 135, 410, 1235, ...

Solving the equation x²+2x+7 using the quadratic formula, the resultant answer is x = -1 ± 2.44949i.

Any quadratic problem can be solved using the quadratic formula.

The equation is first changed to have the form ax²+bx+c=0, where a, b, and c are coefficients.

After that, we enter these coefficients into the following formula:

(-b±√(b²-4ac))/(2a)

Quadratic equations can be solved using one of three main strategies: factoring, the quadratic formula, or completing the square.

So, solving x²+2x+7 using the quadratic formula as follows:

Quadratic formula: (-b±√(b²-4ac))/(2a)

Substitute values and caluclate:

x = (-b±√(b²-4ac))/(2a)

x = (-2±√(2²-4(1)(7))/(2*1)

x = (-2±√4-28)/(2)

x = (-2±√-24)/(2)

Complex roots:
x = (-2±2√6i)/(2)

x = -2/2 ± 2√6i/2

Simplifying fractions:
x = -1 ± √6i

So, we have:
x = -1 ± 2.44949i

Therefore, solving the equation x²+2x+7 using the quadratic formula, the resultant answer is x = -1 ± 2.44949i.

If cara wants to build an 80 foot long rectangular sheep pen in back of her barn then the area of the sheep pen will be 1600 square feet.

An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel opposite sides. A rectangle has two dimensions—length and width—because it is a two-dimensional form.

What is the formula for area of rectangles?

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle as Area = length x width

Length of the sheep pen =80 ft

bought fencing = 180 ft

One side of rectangular sheep pen is covered with barn which is equaling the  width

perimeter of rectangular sheep pen = 2(length +width)

length need to covered is 2 Length+ width

180 =2 length+width

180 = 2 x80 +width

180-160= width

Step-by-step explanation:

Through a given point not contained in a given line, there exists exactly one line parallel to the given line.

In Mathematics, parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and they can never meet. In Geometry, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m represents the slope.

This ultimately implies that, two (2) lines would be parallel to each other when the slope (m₁) of the first line is equal to the slope (m₂) of the second line.

According to the Parallel postulate, there is always exactly one line that is parallel to a given line in the same plane when a point and a line are given, provided that the point is not on that line.
