I need help problems pls man

Answer:

24 minutes

Step-by-step explanation:

Given:

Distance per lap = 2 miles

Speed of Lou Lambert = 160 miles/hr

Speed of Ralph Redding = 170 miles/hr

Speed difference between the two = 170 - 160 = 10 miles/hr

Therefore, we can say that Ralph gains 10 miles in 60 minutes over Lou.

We have to find the time in which Ralph will gain 2 laps i.e. 2 [tex]\times[/tex] 2 = 4 miles.

Let us use unitary method to find the required time.

10 miles are gained by Ralph in 60 minutes

1 mile will be gained in [tex]\frac{60}{10} = 6\ minutes[/tex]

4 miles will be gained in 6 [tex]\times[/tex] 4 = 24 minutes

Answer: 61

By the triangle midsegment theorem, 2(SP)=RQ.

So, 2(x-16)=x+29, meaning x=61.

Answer:

22 inches

Step-by-step explanation:

Diameter=2×Radius

Radius=11

Diameter=11×2=22

Answer:

From what I'm interpreting, you are asking for the sqrt of 22, which then the answer would be point F

Step-by-step explanation:

knowing sqrt 25 = 5 and sqrt of 16 = 4, and knowing 22 is closer to 25, it can be estimated that sqrt of 22 would be closer to 5 however still less than it.

The value of range = 13

The value of mean = 8.4

The value of variance = 23.6

The value of  standard deviation = 4.86

It is the average value of the set given.

It is calculated as:

Mean = Sum of all the values of the set given / Number of values in the set

We have,

Population data set:

2​, 10​, 15​, 2​, 12​, 6​, 14​, 10​, 3​, 10.

Range:

= Highest - Lowest

= 15 - 2

= 13

Now,

Mean.

= (2 + 2 + 3 + 6 + 10 + 10 + 10 + 12 + 14 + 15) /  10
= 84/10

= 8.4

Now,

S = Sum of all (x - Mean)²

S = (2 - 8.4)² + (2 - 8.4)² + (3 - 8.4)² + (6 - 8.4)²+ (10 - 8.4)² + (10 - 8.4)² + (10 - 8.4)² + (12 - 8.4)² + (14 - 8.4)² + (15 - 8.4)²

S = 212.4

n = 10

n - 1 = 9

So,

Variance.

S² = S/(n - 1)

= 212.4/9

= 23.6

Now,

Standard deviation = √S²

So,

= √23.6

= 4.86

Thus,

Range = 13

Mean = 8.4

Variance = 23.6

Standard deviation = 4.86

Answer:

Alexandra's weekly expenses is $234

Step-by-step explanation:

Selling price of 1 kg cumin = $7.20

She sells amount of cumin = 20 kg

Selling price of 90 kg cumin = 90 \times 7.20

Selling price of 90 kg cumin =648

We are given that his weekly profit is $414

We are supposed to find his weekly expense

So, Expense = SP - Profit

Expense = 648-414

Expense=$234

Hence Alexandra's weekly expenses is $234

By applying basic concept of percentage we got that  if She gets successive discounts of 10% followed by 5% off on the boots. The purchase price of Wynona’s boots is 85.5%

Percentage is a number expressed as a fraction of 100.

Here given that Wynona buys some new boots that are priced $85. 79. She gets successive discounts of 10% followed by 5% off on the boots.

First she get 10% discount so she has to pay only 90% amount of original

Now she is getting 5% more off

She has to pay 95% of 90%

so  purchase price 0.95[tex]\times[/tex] 90%

= 85.5%

Answer:

B) 55°

Step-by-step explanation:

The ∑ of all interior angles of a triangle is 180°.

When you see a square in a angle (as seen in the bottom left of the triangle), it means that it is a right angle, or 90° in measurement.

Set the equation:

180 = x + 90 + 35

First, combine like terms:

180 = x + (90 + 35)

180 = x + 125

Next, subtract 125 from both sides of the equation to isolate the x:

180 (-125) = x + 125 (-125)

x = 180 - 125

x = 55

55°, or B) is your answer.

The new surface area is 198.79 ft².

An object's surface area is the total area that all of its surfaces occupy. Many 3D shapes in geometry have various surface areas, which are simply calculable using the formulas.

As per the given diagram:

All the dimensions are mentioned

new surface area is exactly (1/3) of original surface area.

Original surface area = (5 × 6.1) + (5 × 10) + (9.8 × 6.1) + (4.9 × 6.1) + (10 × 5) + (14.8 × 4.9) +  (10 × 5) + (14.8 × 4.9) + (14.8 × 6.1) + (14.9 × 6.1)

Original surface area = 30.5 + 50 + 59.78 + 29.89 + 50 + 72.52 + 50 + 72.52 + 90.28 + 90.89

original surface area = 596.38 ft²

Therefore,

New surface area = (1/3) of original surface area

= (1/3) × 596.38

= 198.79 ft²

Hence, the new surface area is 198.79 ft².
