Answer:

11 feet

Step-by-step explanation:

Length of diagonal of square of side a = √2a

Here value of a = 8 feet

Therefore length of diagonal d = √2×8 = 1.414×8 =    11.312 feet

So after rounding to the nearest tenth the length of diagonal becomes 11 feet

Answer:

7 1/4 pounds

[tex]4\frac{7}{8} + 2\frac{3}{8}[/tex]

[tex]6\frac{7 + 3}{8}[/tex]

= [tex]6\frac{10}{8}[/tex]

convert the improper fraction to a mixed fraction

10/8 = 1 2/8 = 1 1/4

Add the 1 1/4 to 6 = 7 1/4

Answer:

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

Formula

The secant and tangent lines bear the following relationship

(tangent line )^2 = the outside secant line * length of the whole line

Givens

tangent line = 15

outside secant line = x

length of whole secant line = x + 16

Solution

15^2 = x ( x + 16)

15^2 = x^2 + 16x

225 = x^2 + 16x

x^2 + 16x - 225 = 0

Answer and Discussion

The equation has two factors.

(x - 9)(x + 25) =0

x + 25 has no meaning. There cannot be a negative length in this level of geometry.

The answer is x - 9 = 0

x = 9

Answer:

The answer is going to be 13/5 or 2.6

Step-by-step explanation:

You are going to need to divide both sides by the constant of -5 in order to get s by itsef. After you divide both sides by -5, you will get -13/-5 which two negatives divided by a positive so it would be 13/5 or if you turn it into an integer, it would be 2.6

Answer:

y=2 x=2  

Step-by-step explanation:

  x = -2y + 6

3•(-2y+6) - y = 4

  - 7y = -14

7y = 14

y = 2

x = -2y+6

   y = 2

x = -2(2)+6 = 2

x=2

Step-by-step explanation:

solve for y in both equations

subtract 3x from both sides

-y=4-3x

multiply the equation by -1

y=-1(4-3x)

subtract both sides by x

2y=6-x

divide both sides by 2

y=(6-x)/2

-1(3x-4)=(6-x)/2

-3x+4=(6-x)/2

multiply both sides by 2

-6x+8=6-x

add 6x to both sides and subtract 6 to both sides

2=x

put 2 back into x for y=(6-x)/2

y=2

Answer:

Q5: S.A = 216 cm²

Q6: S.A = 254 cm²

Step-by-step explanation:

Q5:

Surface area of a cube = 6a²

a = 6 cm

Plug in the value of a

Surface area of the cube = 6(6²)

= 6(36)

S.A = 216 cm²

Q6:

Given:

Length (L) = 9 cm

Width (W) = 4 cm

Height (H) = 7 cm

Required:

Surface area

Solution:

Surface area of the rectangular prism = 2(LW + LH + HW)

Plug in the values

S.A = 2(9*4 + 9*7 + 7*4)

= 2(36 + 63 + 28)

= 2(127)

S.A = 254 cm²

it will be 151200 is the anwser

There will be a total of 5040 unique ways to make arrangements of 4 cards out of 10 so option (A) will be correct.

When the order of the arrangements counts, a permutation is a numerical approach that establishes the total number of alternative arrangements in a collection.

The number of alternative configurations in a collection of things when the order of the selection is irrelevant is determined by combination.

Given the 4 cards arrangement out of 10

npr = n! /(n-r)!

Here n = 10 , r = 4

10p4 = 10! /(10-4)!

10p4 = 10 × 9 × 8 × 7 × 6! /6!

10p4 = 5040

So there will be a total of 5040 ways to arrange the cards.

Answer:

Due to the difference in the interest rate and the quarterly compounding, Joshua will have $212.24 more than Josiah.

Step-by-step explanation:

Giving the following information:

Joshua:

Initial investment (PV)= $750

Interest rate (i)= 0.0341/4= 0.008525

Number of periods (n)= 18*4= 72 quarters

Josiah:

Initial investment (PV)= $750

Interest rate (i)= 0.0285

Number of periods (n)= 18 years

To calculate the future value of each one, we need to use the following formula:

FV= PV*(1 + i)^n

Joshua:

FV= 750*(1.008525^72)

FV= $1,381.98

Josiah:

FV= 750*(1.0285^18)

FV= $1,169.74

Due to the difference in the interest rate and the quarterly compounding, Joshua will have $212.24 more than Josiah.

Interior degrees of a triangle always add up to 180 degrees

What you would do is add the first two (52+31 = 84)

Subtract this number from 180 to get your remaining degrees
