Well every year it grows 8 inches which means that for every one year it grows 8 inches.

BUT, the tree started out 14 inches so every year you have to add the original 14 inches.

So your equation looks like this:

h=8a+14

Hope this helps :)

Use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole number. The fi

mel-nik [20]

Answer:

Lateral Surface Area = 472 m²

Total Surface Area = 486m²

Step-by-step explanation:

The above prism is a Triangular prism

a) Lateral Surface Area = Perimeter of the Base × H

H = 29m

Perimeter of the Base = (7m + 7.28m + 2m)

= 16.28m

Lateral Surface Area = 16.28m × 29m

= 472.12 m²

Approximately to the nearest whole number = 472 m²

b) Total Surface Area

Triangular prism =

2 Triangles and 3 Rectangles

1st Triangle = 1/2 × base × Height

= 1/2 × 2m × 7m

= 7m²

2nd Triangle = 1/2 × base × height

= 1/2 × 2m × 7m

= 7m²

1st Rectangle = Length × Width

= 29m × 2m = 58m²

2nd Rectangle =

Length × Width

= 29m × 7.28m = 211.12m²

Length × Width

= 29m × 7m = 203m²

Total surface area = 7m² + 7m² + 58m² + 211.12m² + 203m²

= 486.12m²

Approximately to the nearest whole number = 486 m²

Option A is the correct option

HELPPP! Last attempt geometry!!

Helen [10]

Answer:

x1 = 2, y1 = 0

x2 = 2, y2 = 6

Step-by-step explanation:

Each pair of coordinates is (x, y). The first pair is (x1, y1). The second pair is (x2, y2). This means you have ...

x1 = 2, y1 = 0

x2 = 2, y2 = 6

_____

<em>Additional comment</em>

The slope of the line through these points is ...

m = (y2 -y1)/(x2 -x1) = (6 -0)/(2 -2) = 6/0 = undefined

The line through these points is a vertical line with equation x = 2.

An automobile manufacturer is concerned about a possible recall of its best-selling four-door sedan. If there were a recall, the

andrew11 [14]

Answer:

0.27

Step-by-step explanation:

Suppose A is the event of defect in the brake system and B is the event of defect in the fuel system,

We have given,

P(A) = 0.25,

P(B) = 0.17

P(A∩B) = 0.15 ( the probability of defects in both systems simultaneously is 0.15 ),

We know that,

P(A∪B) = P(A) + P(B) - P(A∩B)

= 0.25 + 0.17 - 0.15

= 0.27

Hence, the probability that the defect is the brakes or the fueling system is 0.27.

A PAIR OF JEANS MARKED AT R450 IS SOLD AT DISCOUNT OF 25%.

Stolb23 [73]

Original price is the jeans = Rs450

Discount = 25%

Discount amount

= 25% of 450

= 25%(450)

= 25/100 × 450

= 25/10 × 45

= 5/2 × 45

= 225/2

= Rs112.5

Price after discount

= original price - discount amount

= 450 - 112.5

= Rs337.5

HELP!!!!!

8090 [49]

Hi!

2.06m + 6.13 = 17.78

First subtract 6.13 from both sides
2.06m + 6.13 - 6.13 = 17.78 - 6.13
2.06m = 11.65

Divide by 2.06 on both sides
2.06m/2.06 = 11.65/2.06
m = 5.7

Rachel can travel 5.7 miles.

Hope this helps! :)
