Find the perimeter of an isosceles triangle whose base is 16 cm and whose height is 15 cm.

Answers

Answer:

50 cm

Step-by-step explanation:

The altitude from the vertex to the base bisects the base and divides the triangle into 2 right triangles.

Using one of the right triangles with legs 8 and 15 , then hypotenuse h is

h² = 8² + 15² = 64 + 225 = 289 ( take the square root of both sides )

h = [tex]\sqrt{289}[/tex] = 17

The 2 congruent sides of the isosceles triangle are 17 cm

Then the perimeter P is

P  = 17 + 17 + 16 = 50 cm

Simplify 6 - 3y + (-8y) + 5.2.

The amount of a certain radioactive substance decreases by 15% every hour. If a sample starts with 100 g of this radioactive substance, which function represents the amount of radioactive substance left after x hours?

A- f(x)=100(0.15)^x
B- f(x)=100(0.85)^x
C- f(x)=100(1.15)^x
D-f(x)=100(1.85)^x

Answers

Answer:

A

Step-by-step explanation:

I took the test now that is what I got.

Hope this helps.

The function that represents the amount of radioactive substance left after {x} hours is : f(x)=100(0.15)ˣ.

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that the amount of a certain radioactive substance decreases by 15% every hour. A sample starts with 100 g of this radioactive substance.

The function that represents the amount of radioactive substance left after {x} hours is -

f(x)=100(0.15)ˣ

Therefore, the function that represents the amount of radioactive substance left after {x} hours is : f(x)=100(0.15)ˣ.

What is the area of this polygon?

Answers

Answer:

45

Step-by-step explanation:

The area can be found by sectioning the polygon into three shapes.  A rectangle with an area of 18 inches can be found at the bottom, while the top can be divided into two triangles.  The triangle on the left has an area of 18in^2, (1/2*6*6) while the triangle on the right has an area of 9 in^2 (1/2*6*3).

Total area for all three shapes is 45 sq. inches

Lanu draws a rectangle that is 10 inches wide and 20 inches

F 5 inches wide and 25 inches long
G 8 inches wide and 25 inches long
H 15 inches wide and 15 inches long
J 15 inches wide and 25 inches long

Answers

The answer is G because 10x20=200 and 8x25=200

Answer:

G

Step-by-step explanation:

A 10 x 20 inch rectangle has an area of 200 square inches. Therefore, we must find the rectangle that is also 200 square inches.

The formula of finding the area of a rectangle is multiplying width times length.

F) 5 * 25 = 125

G) 8 * 25 = 200

H) 15 * 15 = 225

J) 15 * 25 = 375

Therefore, rectangle G has the same area, since it is also 200 square inches.

○=> Correct option :[tex]\color{plum}\tt\bold{(B)}[/tex]○=> Steps to derive correct option :

We know that :

[tex]\color{hotpink} \tt \: circumference \: of \: a \: circle\color{plum} = 2\pi r[/tex]

So, let the diameter of this circle be x.

Which means :

[tex] =\tt2 \times \pi \times r[/tex]

[tex] =\tt 2 \times x \times \pi = 12\pi[/tex]

[tex] =\tt 2x\pi = 12\pi[/tex]

[tex] =\tt x = \frac{12}{2} [/tex]

[tex] = \tt \: x = 6 \: m[/tex]

Thus, the radius of the circle Robert drew = 6 m

Since the circle in option B has a radius of 6 m, it is the circle Robert drew.

▪︎Therefore, the correct option is (B)

You have $75 and need to buy 9 books at the bookstore and each book costs d dollars.

​Write an algebraic expression to represent the amount of money left over.

Answers

Answer:

75-9d

Step-by-step explanation:

Hello,

The Answer to the question is 75-9d let me explain why,

you are asking, how much money is leftover. For me to get that I need to know that for every book it cost "d" dollars.

You know you have $75, and you need 9 books, we don't know how much they cost but we don't really need to.

75 - 9d

75 is the total. You need to subtract it by how many books your buying, 9.

The books are d amount of dollars, so we put 9d so that we know that for every 1 book it cost d amount so technically 9 is the amount of books times d, how much 1 book costs

Hope you can understand, I was having some trouble finding a way to explain it so my bad.

Also, I haven't done that in a while so sorry if I'm wrong

Answer:

32

63

Step-by-step explanation:

m<BCA=180-148-32 Subtract 180-148 b/c x<BCA is along the straight line ACD. A straight line will have an angle of 180 degrees.

m<CAB=180-32-85=63 All triangles have angles which add up to 180 degrees. Subtract 32 and 85 from 180 to get 63.

Step-by-step explanation:

148 + x = 180

x = 180 - 148

x = 32

Find m<CAB basically means find the measure of the angle of A ( m<A )

m<B + m<A + x = 180

85 + m<A + 32 = 180

117 + m<A = 180

m<A = 180 - 117

m< A = 63, so m<CAB = 63

And m<BCA means find the measure of angle C(m<C) or as we did it earlier as x, which is the same thing.

So m<BCA = 32
