how do i find the perimeter of a triangle

Add the two angles and then subtract from 180* to find the missing angle
So,
145* + 15* = 160*

180* - 160* = 20*


Answer: x = 20*

Answer:

(2) $1,699.50

Step-by-step explanation:

A(t) = P(1 + r/n)^nt

1500(1 + .025/12)^5*12

= $1699.50

$1,699.50 represents the value of an investment with a principal of $1500 with a nominal interest rate of 2.5% compounded monthly after 5 years.

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

Given that an investment with a principal of $1500 with a nominal interest rate of 2.5% compounded monthly after 5 years,

Amount = P(1+r/n)^nt

= 1500(1+0.25/12)^5*12

= $1699.50

Hence, $1,699.50 represents the value of an investment with a principal of $1500 with a nominal interest rate of 2.5% compounded monthly after 5 years.

IF SO, LETS SOLVE FOR IT!

9^3

= 9 * 9 * 9

= 81 * 9

= 729

Therefore, your answer is most likely:

[729] So, the base number is probably 5 and the exponent is probably 3

Answer:

36

Step-by-step explanation:

the total sugar bags to be distributed= x=48

the total rice bags to be distributed= y=72
each family can take a package containing= 1x +2y
as each family can have 2 rice bags thus we can estimate the total number of families that can benefit by diving total no of rice bags by 2 which will be = 72/2 =36

the rice can be divided into 36 families
while the sugar bags can be divided into 48 families
as these have to be divided into packages so there will be 36 packages
that can be distributed into 36 families.

Answer: OD 81007 in.2

Step-by-step explanation:

Use formula for area of circle, which is A = πr²

The radius is squared, so if the radius or a new circle is 6 times larger (multiplied by 6), the difference in area will be 36 times greater.  So the area is

225π(36) = 8,100π

Answer:

Step-by-step explanation:

Question:

A circle has an area of 225[tex]\pi[/tex] square inches.  If the radius of the circle is multiplied by 6, then what is the area of the new circle?

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

area of a circle = [tex]\pi r^2[/tex]   (where r is the radius)

⇒ [tex]\pi r^2=225\pi[/tex] in²

If the radius is multiplied by 6, then r = 6r

⇒ area = [tex]\pi (6r)^2=36\pi r^2[/tex]

Therefore, if [tex]\pi r^2=225\pi[/tex]

then [tex]36\pi r^2 = 36 \times 225\pi =8100\pi[/tex]

Answer:

total blocks are 20 and prisms are 28

Step-by-step explanation:

There are 20 blocks needed for tower A, and 43.75 blocks needed for tower B

From the tape diagrams, we have the following ratio

Prism : Pyramid = 4 : 1

From the table, we have:

Tower A = 16 prisms

So, the ratio becomes

16 : Pyramid = 4 : 1

Multiply the ratio on the right-side by 4

16 : Pyramid = 16 : 4

By comparison, we have:

Pyramid = 4

This means that, 4 pyramid blocks are needed for tower A

So, the total number of blocks needed is:

Total = Pyramid + Prism

This gives

Total = 4 + 16

Evaluate the sum

Total = 20

Hence, there are 20 blocks needed for tower A

For table B, we have:

Tower A = 35 prisms

So, the ratio becomes

35 : Pyramid = 4 : 1

Express as fractions

[tex]\frac{Pyramid}{35} = \frac 14[/tex]

Multiply through by 35

Pyramid = 8.75

This means that, 8.75 pyramid blocks are needed for tower B

So, the total number of blocks needed is:

Total = 8.75 + 35

Evaluate the sum

Total = 43.75

Hence, there are 43.75 blocks needed for tower B

Answer:

A. ( x + 3 )² = 25

Step-by-step explanation:

2x² + 12x = 32

x² + 6x + 9 = 16 + 9              [ addition of 9 from both sides ]

( x + 3 )² = 25

Answer:

(-8,-10)

Step-by-step explanation:

we have the two equations x-2y=12 and y=3x+14.

I'm going to assume this is a system of equations and we are looking for the solution.

we can use the substitution method as y is "defined".

x-2y= 12

substitute y = 3x + 14

x-2(3x+14)=12

distribute

x - 6x -28 = 12

combine like terms

-5x - 28 = 12

add 28 to both sides

-5x = 40

divide both sides by -5

x = -8

Now we plug in the value of x into one of the equations and solve for y

y = 3x + 14

x = -8

y = 3(-8) + 14

y = -24 + 14

y = 10

the solution is (-8,-10)
