Find ABpicture Is Attached

Answers

Answer 1

Answer: AB = 15 units long.

Step-by-step explanation:

The triangles are identical.

You can infer this from both triangles sharing the side of BD and AD and CD marked as equal in length.

When triangles are identical, all three sides and angles are identical in length and measure, respectively.

Knowing this, we can set the sides of "5x" and "4x + 3" equal to each other in an equation to solve for x:

5x = 4x + 3

x = 3

When x equals 3, multiply x by 5 to find the side length of AB.

AB = 15 units long.

An equilateral triangle has a side length of 7 cm. If a perpendicular is dropped from a corner, what is the length of the perpendicular?

Answers

Answer:

6.06cm

Step-by-step explanation:

An equilateral triangle is a triangle that has all its sides equal. If the given  equilateral triangle has a side length of 7 cm, then all its sides are 7cm each. To get the length of the perpendicular dropped from a corner. we will use the Pythagoras theorem.

According to the theorem,

hyp² = opp²+adj²

Lets take the height as the opposite side of one of the right angled triangle as shown in the attachment.

hyp = 7cm and adj = 7/2 = 3.5cm

opp² = 7² - 3.5²

opp² = 49 - 12.25

Opp = √36.75

Opp = 6.06cm

This shows that the length of the perpendicular is 6.06m

in a class of 60 student, the number of student who passed biology is 6 more than the number who passed chemistry every student passed both at least one of the two subjects and 8 student passed both subject​

Answers

Answer:

Brainliest Please

A, B, D

Step-by-step explanation:

Because if you subtract one of the constants from both sides then you should only have equal variables. In other words, both sides have to be identical in this situation.

33x-33= 33x + 25

33x = 33x + 58 No matter what you make x, the right will be 58 bigger than the right so there is no solution.

33x+33=33x+25

33x+8= 33x nope no solution

33x+25=33x+25

33x = 33x both sides identical so there is a solution

33x-25 = 33x +25

33x= 33x+50

Which expression represents the area of the base of the cone? A cone with diameter 12 inches, height 8 inches, and slant height 10 inches. B = pi r squared (pi) (5 squared) (pi) (6 squared) (pi) (10 squared) (pi) (12 squared)

Answers

Answer: (pi) (6 squared)

Step-by-step explanation:

Hi, the base area of a cone is a circle, so, to answer this question we have to apply the next formula:

Area of a circle: (pi) radius^2

The diameter (d) of a circle is equal to: 2 radius

So:

D = 2r

Replacing with the value given:

12 =2r

12/2=r

radius= 6 inches

Back with the Area formula:

A = (pi) 6^2

How many 4's are expected when a 6 sided die is rolled 90 times?

Answers

The 4 should be rolled 15 times, for every 90 rolls.

First you want to create the two into fractions-> 1/6 = x/90
The 1 in 1/6 is the chance of 4 showing in a dice roll. The x in x/90 is the chance how many 4’s there should be in 90 rolls.

You can turn that into 6x = 90 by cross multiplying the two fractions. Then turn that into x = 15.

A new phone costs $450. There is a 40% discount on the price of the phone and an 8% sales tax on the discount price. What is the final cost of the phone after the discount and the sales tax?

What is mean by Probability?

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one

Given that;

You spin the spinner twice.

Now, The probability of the spinner landing on 3 is,

⇒ 1/3.

And, The probability of it landing on 2 is,

⇒ 1/3.

Hence, The probability of landing on a 3 and then landing on a 2 is,

⇒ 1/3 × 1/3

The reason a is 54 is because of alternate angles or z angles and
B is 56 because the angles of a triangle equal 180 so you add 70 and 54 together to get 124 and then subtract 124 from 180 which is 56

Answer:

number five: 37.065 number six 241

Step-by-step explanation:

FOR NUMBER FIVE:

so for the rectangles, the formula is L * W.   L for length W for width

so 5×3 = 15. and there are 2 rectangles with the same measurment so its

15 + 15 which is 30 (for both rectangles)

and for the circle formula its pi r^2 where pi is 3.14 and r is radius

so 3.14 × 3^2 = 28.26. but since its a quarter of a circle, divide it by four which is 7.065.

so 30 + 7.065 = 37.065

FOR NUMBER SIX:

the area of a triangle formula is b * h ÷ 2 where b is base and h is height

so its 22 * 8 / 2 = 88

and for the trapezoid the formula is [tex]\frac{a+b}{2} h[/tex] where a and b are the bases and h is height

so its[tex]\frac{12+22}{2} *9[/tex] = 153

88+153= 241

What are arithmetic and geometric sequence?

An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference

d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.

In a geometric sequence numbers are written in the same common ratio(r).

It means every next number is a multiple of a common constant and the previous number.

r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.

Given, a geometric sequence  8, 16, 32,... which has a common ratio(r)

= 16/8 and first term a₁ = 8.

We know nth term of a geometric sequence is aₙ = a₁rⁿ⁻¹.

∴ 12t term of the geometric sequence is a₁₂ = 8.2¹²⁻¹

=  8.2¹¹.

= 8.2048.

= 16384.
