Regular quadrilateral pyramid with base edge b=55 mm and lateral edge l = 7cm. Find the sum of all edges

Answers

Answer 1

Answer:

50cm or 500mm

Step-by-step explanation:

There are 4 base edges and 4 lateral edges, therefore, multiply the number for both edges by 4 and add.

Considering the fact that we were given two units of measurement, millimeters and centimeters, but we know that there are 10mm (millimeters) in a cm (centimeter) , we can just divide 55 by 10 to get 5.5.

¦

Therefore;

5.5 x 4 = 22

7 x 4 = 28

28 + 22 = 50cm

The diagram can be drawn in order to assist in answering the question.

(b) Give the equation of a line which is parallel to line y=2x and
passes through (0,3).

Answers

All lines parallel to y=2x-3 will have the same slope as y=2x-3. So how do you find the slope of y=2x-3? Very simple! When written in slope-intercept form you simply look at the coefficient of the ‘x’ term. In this instance the coefficient is 2. Therefore any equation that has a slope of 2 will be parallel to y=2x-3. In general we can say that the family of equations parallel to y=2x-3 is y=2x+b where b is the y-intercept.

Step-by-step explanation:

Assuming this is the Pythagorean theorem we would usually solve for c but c is already found so we have to work backwards so... 15 × 15 = 225

9 × 9 = 81 225 - 81 = 144 √144 = 12 therefore 12 is the answer Hope that helps!

If tan0 = 3/4, find sin0

Answers

Answer:

b

Step-by-step explanation:

Answer:

[tex]\text{b. }\sin \theta =\frac{3}{5}[/tex]

Step-by-step explanation:

In a right triangle only, the tangent of an angle is equal to its opposite side divided by its adjacent side. If [tex]\tan \theta =\frac{3}{4}[/tex] as given in the problem, then the opposite side of angle theta is 3 and its adjacent side is 4. Thus, the hypotenuse of the triangle must be [tex]h=\sqrt{4^2+3^2}=\sqrt{25}=5[/tex].

The sine of an angle in a right triangle is equal to its opposite side divided by its hypotenuse. Therefore, [tex]\sin \theta =\frac{3}{5}[/tex] (o/h).

7x-5y=15

solve for y, please help

Answers

Answer:

7x-15/5

Step-by-step explanation:

Given :-

A linear equation in two variable is given to us . That is 7x - 5y = 15.

And , we need to solve for y in terms of x . So taking the given equation ,

[tex]:\implies[/tex] 7x - 5y = 15

[tex]:\implies[/tex] -5y = 15 - 7x

[tex]:\implies[/tex] 5y = 7x - 15

[tex]:\implies[/tex] y = ( 7x - 15)/5

Hence the required answer is 7x-15/5.

male female eats oysters 205 113 does not eat oysters 98 322 what is the probability that one of the people chosen from this survey was a female and does not eat oysters could someone explain?

Answers

Answer:

322 /738 ; 0.436

Step-by-step explanation:

__________________ M____ F__

Eat oysters ________ 205 __ 113

Does not eat oysters _ 98 __ 322

Probability of choosing a female and does not eat oysters :

Number of (F n Does not eat oyster) = 322 (from table)

Total number of sample : (205+98+113+322) = 738

Hence,

Probability of choosing a female and does not eat oysters ;

Number of (F n Does not eat oyster) = 322 (from table) / total number of samples

= 322 / 738

= 0.436

Answers

Answer:

Area = 5200 ft²

Step-by-step explanation:

First let us find the area of the house.

Area = l × w

Area = 30 ft × 40 ft

Area = 1200 ft²

Now let us find the area of the backyard.

Area = l × w

Area = 80 ft × 50 ft

Area = 4000 ft²

Now that we have found the area of the house and the backyard, it asks us to find the total area of house and the backyard. To find the answer, you will both, the area of house and the area of the backyard.

Area of house + Area of backyard

1200 ft² + 4000 ft²

5200 ft²

A company produces packets of soap powder labeled "Giant size 32 Ounces." The actual weight of soap powder in a box has a normal distribution with a mean of 33 oz. And a standard deviation of 0.8 oz. The proportion of packets that are underweight (i.E. Weight less than 32 oz.) are

Answers

Answer:

0.1057

Step-by-step explanation:

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score = 32 oz

μ is the population mean = 33 oz

σ is the population standard deviation = 0.8oz

For x < 32 oz

z = 32 - 33/0.8

z = -1.25

Probability value from Z-Table:

P(x<32) = 0.10565

Approximately = 0.1057

Therefore, the proportion of packets that are underweight (i.e. Weight less than 32 oz.) are 0.1057.

Explanation:

At a grocery store, bananas cost $1.60 per pound. Today there is a 10% discount. How much would 4 1/2 pounds of bananas cost with the discount? Show work or explain how you reached your answer.

Answers

Answer:

$6.48

Step-by-step explanation:

The discount is 10%. That means you pay 90% of the price.

At the regular price, 4 1/2 lb of bananas cost:

$1.60/lb * 4.5 lb = $7.20

Since with the 10% discount, you pay 90% of the original price, now we calculate 90% of the original price.

90% of $7.20 = 0.9 * $7.20 = $6.48

Answer: 4.5 lb cost $6.48 with the 10% discount
