• Assuming that the other side represent x and the other side represent y,( 4cm;6cm) , and that we are drawing a right angle triangle .We can constuct a triangle as follows :

• We can find the value of side h by using Pythagorean theorem:

• Subsequently, we will find angle angle , as shown in the diagram above as follows:

• Since we have angle ,= 56.3 °, ,we can find, angle :

• + + 90° = 180 °,....(angles in a triangle adds up to 180°)

∴ = 180° -90° -56.3°

=33.7°

Answer:

See below

Step-by-step explanation:

We have to reflect the triangle across the y-axis.

If we have a point P = (x,y) and we reflect it across the y-axis, we will change the x-coordinate to its opposite value and and the y-coordinate is kept the same.

The image point then is P' = (-x,y).

Then, to reflect the triangle, we have to reflect the three vertices and then join the vertices.

We can then reflect the vertices as:

Answer:

Slope formula is given as (y2-y1) ÷ (x2-x1) or (y1-y2) ÷ (x1-x2), where x and y are the coordinates of the points.

Slope = (-7-(-6)) ÷ (0-(-8))

= (-7+6) ÷ (0+8)

The probability that a family’s first child will be born with down syndrome is 1/5000

Number of first borne babies  = 30000

Number of first borne babies having Down syndrome = 6

Probability is defined as the ratio of number of favorable outcomes to the total outcome.

Probability =  (number of favorable outcomes)/(total outcome)

We have to find the probability that a family’s first child will be born with down syndrome. So, Number of first borne babies having Down syndrome is equal to the total number of favorable outcomes and  Number of first borne babies will also be equal to total outcome. Hence we can write,

Probability = (number of favorable outcomes)/(total outcome)

Probability = 6/30000

Probability = 1/5000

So, the required probability is 1/5000.

Yes, because the ladder will reach 16 feet high

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem.

According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.

Given:

Hypotenuse= 20 feet

base= 12 feet

Using Pythagoras theorem

H²= P² + B²

20² =12² +P²

P²= 400-144

P²= 256

P= 16 FEET.

Hence, Yes, because the ladder will reach 16 feet high

The no. of students who usually bring their own lunch is 15.

The ratio is a comparison between two or more quantities in simplest form.

Given there are 36 students in an s2a class some of them bring their own lunch and the others buy their lunch.

Assuming x students bring their own lunch hence (36 - x) students buy their lunch.

(1/5)th of the student who brings their own lunch is (1/5)×x = (x/5).

∴ x - (x/5) : (36 - x) + (x/5) = 1 : 2.  (The reduced students are added to the      

                                                                              other category).

4x/5 : 36 - 4x/5 = 1 : 2.

4x/5 : (180 - 4x)/5 = 1 : 2.

(4x/5)÷(180 - 4x)/5 = 1/2.

(4x/5)×5/(180 - 4x) = 1/2.

4x/(180 - 4x) = 1/2.

4x = (180 - 4x)/2.

8x = 180 - 4x.

12x = 180.

x = 15.

To solve the question, we will be using a Venn Diagram. Let's list down what's given first:

855 drank alcohol

657 smoked cigarettes

192 used illegal drugs

418 both drank alcohol and smoked cigarettes

109 drank alcohol and used illegal drugs

116 smoked cigarettes and used illegal drugs

88 engaged in all three

and 251 engaged in none of these

We will draw a Venn Diagram with 3 circles, one for each vice. Then we will start with the intersection of all three and the area outside of the circles (for those who do not engage in vices).

Because we know how many engaged in all 3 vices, we can deduct that number from those who belong to the intersection of 2 vices since they have already been counted in that too.

418 - 88 = 330 drank and smoked, but not used drugs

109 - 88 = 21 drank and used drugs, but not smoked

116 - 88 = 28 smoked and used drugs but not drank

Then, we subtract the numbers in each circle from the total for each vice.

855 - (330 + 88 + 21) = 416 drank only

657 - (330 + 88 + 28) = 211 smoked only

192 - (88 + 21 + 28) = 55 used drugs only

To find the total number of surveyed students, we just need to add all the numbers in the Venn Diagram.

416 + 330 + 88 + 21 + 211 + 28 + 55 + 251 = 1,400

Therefore, there were 1,400 students who were surveyed.

The amount of wall surface in square feet is there to paint is: 364 square ft. While the floor area is 169.58sq ft. See the calculations below:

The square foot is an imperial measure of area and a customary unit of area in most countries. It is defined as the area of a square with one-foot sides.

The calculation for the above solution is given as:

Step I - Recall the Given Stats:

Dimensions of the room are:

12′-4″ by 13′-9″ with an 8′-0″ ceiling height has one door 3′ × 7′ and two windows 4′ square.

Let Lenght (l) = 13'9" = 13(9/12) ft = 13(3/4) = 55/4 ft.

Let Width(w) = 12'4" = 12(4/12) ft = 12(1/3)ft = 37/3 ft

Let Height h = 8'0" = 8ft.

Recall that we have a door with dimensions 3' x 7' and two windows 4'x4'

Step II - A) Surface area of the wall to be painted is:

Area of 4 walls less (area of door plus area of window)

Surface Area = 2LH + 2WH - ((3 x7) + 2(4x4))

= 2(l +w)h - (21 + 32)
= 2 ((55/4) + (37/3))8 -53

= 220 + 592/3 - 53
= 167 + 592

= (501+ 592)/3
= 1093/3

Hence,

The Surface Area to be painted is = 364.33 Sq ft.

Step III - B) The Area of the Floor = Lx W

= (55/4) x (37/3)

= 2035/12

= 169.583333333

Hence,

Area of the Floor is approximately = 169.58

A. How much wall surface in square feet is there to paint?

B. What is the floor area?

Answer:

3x - 4

Step-by-step explanation:

"Difference" is a clue word that tells you to use subtraction. The other clue word is "times" but that means times, or multiplication and is pretty straight forward.

"Three times a number" means to multiply a number, but we don't know the number, so we use a variable (a letter). I put x but you could use n or c or almost any letter for the variable.

"the difference of ___ and ___" means to subtract those two things.

So we get 3x - 4

As calculated by the given ratios, 36 more skiers were there than snowboarders at the local resort on Saturday.

What is ratio?

A ratio illustrates how two or more values differ in terms of size.

Ratios can be displayed in a variety of ways, including as decimals (after dividing one value by the whole), percentages (after dividing one value by the entire), and using the ":" or "/" to separate values.

As given in the question,

Ratio of Snowboarders to Skiers

On Friday: ratio is 6:2

On Saturday: 5:3

Population = 144

Now, lets calculate the number of snowboarders and skiers at Saturday:

Given ratio: 5:3

total = 5+3

total = 8

No. of skiers is:

= (3/8)(144)

Answer:

-42/7 and 42/-7

Explanation:

The absolute value of a number is represented by:

The lines represent absolute value of a number x, and what it does is that it makes everything into a positive number.

For example |-5|=5 and |5|=5, so we always have two options with an absolute value: that it comes from a negative number or that it comes from a positive number.

In this case we have that a number with an absolute value of 42 (it could be |-42|=42 or |42|=42) divided by a number with an absolute value of 7 (it could be |-7|=7 or |7|=7) the quotient is -6.

One possible numberic equation is:
