Step-by-step explanation:

24/8=3

3x5=15

Answer:

bratdth = 8 m

perimeter = 12 m

we know

perimeter of rectangle = 2(l+b)

24=2(l+8)

24=2l+16

24-16=2l

8=2l

8/2=l

l=4m

for second picture

breadth = 5m

length =4 m

p =?

we know

p= 2(l+b)

p=2(4+5)

p=2×9

p=18m

Answer:

The surface area of the pyramid is 340.2 cm²

Step-by-step explanation:

We can find the surface area of this pyramid by adding up the area of its square base and the four side triangles.

We're told that the base has a side length of 9.0 cm, so we know that its area is (9.0cm)², or 81cm²

We are told that the height of the side triangles is 14.4 cm.  To find the area of a triangle, simply multiply its width times its height, and divide by two:

(14.4cm × 9cm) ÷ 2

= 129.6cm² ÷ 2

= 64.8 cm²

Now we can multiply that by 4, and add it to the base area to get the total surface area of the pyramid:

4 × 64.8cm² + 81cm²

= 259.2cm² + 81cm²

= 340.2cm²

Step-by-step explanation:

Slope is always rise over run.

"rise" up -1 or down in this situation because it is a negative

then 'run' or move to the right 2 places on the x-axis

Answer:

Amounts of first payment =  $369.60

Amounts of Second and third payment =  $277.20

Step-by-step explanation:

Given:

Annual premium = $924

First payment = 40%

Second payment = 30%

Third payment = 30%

Find:

Amounts of three payments

Computation:

Amounts of first payment = $924 x 40%

Amounts of first payment =  $369.60

Amounts of Second payment = $924 x 30%

Amounts of Second payment =  $277.20

Amounts of third payment = $924 x 30%

Amounts of third payment =  $277.20

Answer:

Question 3: 93    Question 4: -18

Step-by-step explanation:

Use Order of Operations (BEDMAS - Brackets Exponents Division Multiplication Addition and Subtraction).

Question 3:

Start with the numbers inside the brackets.

3^2 (4+6) + 3

= 3^2 (10) + 3

Then, solve the exponents.

= 9 (10) + 3

Multiply 9 and 10.

= 90 + 3

Add the numbers.

= 93

Question 4:

Again, start with the brackets.

3 (4+2) - 6^2

= 3 (6) - 6^2

Then, solve the exponent.

= 3 (6) - 36

Multiply 3 and 6.

= 18 - 36

Subtract the numbers.

= -18 (You can do 36 - 18 which is 18, then add the negative sign)

Answer:

x=2

Step-by-step explanation:

Given: 3ln2 +ln8=2ln(4x)

          ⇒ln [tex]2^{3}[/tex]+ln8=2ln(4x)            ( m ln (n)= ln([tex]n^{m}[/tex]))

             ⇒ ln8+ln8= 2ln(4x)

            ⇒ 2ln8= 2ln(4x)

   comparing both sides, we get

  8=4x

  ⇒x=2

Answer:

x = 2.857 [rounded]

Step-by-step explanation:

17 x 2 = 34.

Next, we combine.

34 - 14 = 20.

Lastly, we divide 20 by 7.

20 / 7 = 2.857

[The answer is a decimal that doesn't end, but I rounded it for simplicity.]

Answer:

The center of dilation is a fixed point in the plane. If the scale factor is greater than 1, the image is an enlargement (a stretch). If the scale factor is between 0 and 1, the image is a reduction (a shrink). If the scale factor is 1, the figure and the image are congruent.

Answer:

Ariana has 7 dimes and 14 nickels

Step-by-step explanation:

Nickel = 0.05

Dime = 0.10

1.40 ÷ 2 = 0.70

7 x 2 = 14

because Adriana has twice the nickels as dimes and half of the 1.40 is dimes so the other half is nickels.

nickels x 2 = 14

Step-by-step explanation:

The slope is 0

Because its not going up, the slope isn’t negative or positive so its moving but it isn’t rising so its 0. If it were going up but not side there would be no slope, but for this its 0

Answer:

The 8th term of the geometric sequence 5, -15, 45, ... is:

[tex]a_8=-10935[/tex]

Step-by-step explanation:

Given the geometric sequence

5, -15, 45, ...

The first element of the geometric sequence is

[tex]a_1=5[/tex]

A geometric sequence has a constant ratio 'r' and is defined by  

[tex]a_n=a_1\cdot r^{n-1}[/tex]

computing the ratios of all the adjacent terms

[tex]\frac{-15}{5}=-3,\:\quad \frac{45}{-15}=-3[/tex]

The ratio between all the adjacent terms is the same and equal to

[tex]r=-3[/tex]

substituting [tex]a_1=5[/tex], and [tex]r=-3[/tex] in the nth term

[tex]a_n=a_1\cdot r^{n-1}[/tex]

[tex]a_n=5\left(-3\right)^{n-1}[/tex]

Determining the 8th term:

We have already got the nth term

[tex]a_n=5\left(-3\right)^{n-1}[/tex]

substituting n = 8 to determine the 8th term

[tex]a_n=5\left(-3\right)^{n-1}[/tex]

[tex]a_8=5\left(-3\right)^{8-1}[/tex]

[tex]a_8=5\left(-3^7\right)[/tex]

[tex]a_8=-5\cdot \:3^7[/tex]

[tex]a_8=-5\cdot \:2187[/tex]

[tex]a_8=-10935[/tex]

Therefore, the 8th term of the geometric sequence 5, -15, 45, ... is:

[tex]a_8=-10935[/tex]
