Find the area of the shape shown below.

Answers

Answer:

18.75

Step-by-step explanation:

The formula to find the area of a triangle is

A= [tex]\frac{1}{2}[/tex]*b*h

The formula to find the area of a rectangle is simply the length times the base.

Here, you can separate the shapes, two triangle and one rectangle to make it easier to find. Subtract 7.5 and 2.5 to get 5, which will be the base measurements for the triangles.

Next, find the area for the triangles: [tex]\frac{1}{2}[/tex] x 5 x 2.5= 6.25, however, you have two triangles, so multiply by two to get 12.5.

Now, find the area of the rectangle, 2.5 +2.5= 6.25

Lastly, add the measurements together, 12.5 +6.25= 18.75

Answers

Answer:

no, 72 km/hr is equal to 20m per sec

Step-by-step explanation:

From which store should Dylan make his purchase if he wants to get the best price per unit?

Answers

Answer:

Store 1

Step-by-step explanation:

Given

See attachment

Required

Determine the store with the best price per unit

It should be noted that the store with the best has the least price per unit.

So, we have:

Store 1

[tex]Quantity = 10\ ft[/tex]

[tex]Price = \$2.50[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$2.50}{10\ ft}[/tex]

Rate = $0.250 per feet

Store 2

[tex]Quantity = 2\ yd[/tex]

[tex]Price = \$1.85[/tex]

Convert quantity to feet

[tex]Quantity = 2 * 3ft = 6ft[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$1.85}{6\ ft}[/tex]

Rate = $0.308 per feet

Store 3

[tex]Quantity = 12\ ft[/tex]

[tex]Price = \$3.40[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$3.40}{12\ ft}[/tex]

Rate = $0.283 per feet

Store 4

[tex]Quantity = 5\ yd[/tex]

[tex]Price = \$4.00[/tex]

Convert quantity to feet

[tex]Quantity = 5 * 3ft = 15ft[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$4.00}{15\ ft}[/tex]

Rate = $0.267 per feet

From the calculations above; store 1 has the least unit rate.

Hence, store 1 has the best price per unit

Answers

Answer:

A. (2i)(8) = d. 16i

B. 16i³ = b. -16i

C. (2i)⁴ = a. 16

D. (2i)(8i) = c. -16

Step-by-step explanation:

A. Multiply 2i by 8 to get 16i, which corresponds to d.

B. The exponent is 3 more than a mulitple of 4 in 16i³, so the answer is negative. -16i corresponds to b.

C. (2i)⁴ has an exponent that is a multiple of 4, so the i isn't needed. 16 corresponds to a.

D. (2i)(8i) simplifies to 2(8) * i². The exponent is 2 more than a multiple of 4, so the answer is negative, without an i. -16 corresponds to c.

Write and solve a real-world problem that can be represented by the expression (–3)(5), then solve it

Answers

Answer and explanation:

(-3)(5) evaluates to -3×5=-15

A real world problem that would represent this would be a case where 5 fruit vendors each give out 3 fruits to 3 of their customers in the spirit of Christmas. Each vendor gives out(subtracts fruits from fruit stock) 3 of their fruits= -3 fruits for each vendor. There are a total of 5 fruit vendors therefore -3×5= -15 fruits given out by all 5 fruit vendors in total. To better understand this, we could compare this to if the vendor were to get(add to stock of fruits) fruits and not actually give out fruits. This would be 3×5= 15 fruits gotten by all the 5 vendors in total.

A high school drama club is performing a musical to benefit a local charity. Tickets are $5. They also receive donations if $500. They wants to raise at least $2000. How many tickets should they sell to reach their target

Answers

Answer: 300 tickets

Step-by-step explanation:

The drama club wants to raise at least $2,000. They have already received donations of $500 so the amount left till target is:

= 2,000 - 500

= $1,500

Tickets are being sold at $5 so the number of tickets needed to get to $1,500 is:

= 1,500/5

= 300 tickets

Predict the rate of change for the depth of the diver for the intervals of [3, 4], [4, 5], and [5, 6].

Answers

Answer:

The rate of change is 1

Step-by-step explanation:

Given

[tex]\{[3, 4], [4, 5], [5, 6]\}[/tex]

Required

Predict the rate of change

Average rate of change (R) is calculated using:

[tex]R = \frac{f(b) - f(a)}{b - a}[/tex]

Here, we have:

[tex][a,f(a)] = [3,4][/tex] and

[tex][b,f(b)] = [5,6][/tex]

Substitute these values in the above equation

[tex]R = \frac{6 - 4}{5 -3}[/tex]

[tex]R = \frac{2}{2}[/tex]

[tex]R = 1[/tex]

Also, check the rate of change using:

[tex][a,f(a)] = [3,4][/tex] and

[tex][b,f(b)] = [4,5][/tex]

The equation: [tex]R = \frac{f(b) - f(a)}{b - a}[/tex] becomes

[tex]R = \frac{5-4}{4-3}[/tex]

[tex]R = \frac{1}{1}[/tex]

[tex]R = 1[/tex]

Hence, the rate of change is 1

Which set of numbers can represent the side lengths, in inches, of an acute triangle?
o 4,5,7
O 5,7,8
O 6,7, 10
O 7.9, 12

Answers

Answer:

 5 , 7 , 8 represent the side of acute angled triangle

Set B with sides 5 , 7 , 8 represent the side of acute angled triangle.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that:

Set of numbers.

Now, We use the following result:

When given 3 triangle sides then to determine if the triangle is acute angled , right angled or obtuse angled.

First find Square all 3 sides, then Sum the squares of the 2 shortest sides and then Compare the sum to the square of the last side.

if sum > Square of last side ⇒ it is Acute Triangle

if sum = Square of last side ⇒ it is Right Triangle

if sum < Square of last side ⇒ it is Obtuse Triangle  

a). 4  , 5 , 7

4² = 16 ,  5² = 25 , 7² = 49

16 + 25 = 41

Hence, 41 < 49

⇒ It is an Obtuse Triangle.

b). 5 , 7 , 8

5² = 25 , 7² = 49 , 8² = 64

25 + 49 = 74

Hence, 74 > 64

⇒ It is an acute Triangle.

c). 6 , 7 , 10

6² = 36 , 7² = 49 , 10² = 100

36 + 49 = 85

Hence, 85 < 100

⇒ It is an Obtuse Triangle.

d). 7 , 9 , 12

7² = 49 , 9² = 81 , 12² = 144

49 + 81 = 130

Hence, 130 < 144

⇒ It is an Obtuse Triangle.

Therefore, Set B with sides 5 , 7 , 8 represent the side of acute angled triangle.

Determine whether statement (3) follows from statements (1) and (2) by the Law of Detachment or the Law of Syllogism. If it does, state which law was used. If it does not, write invalid.(1) If you use a pencil you can erase mistakes. (2) If you can erase mistakes your paper will be neater. (3) If you use a pencil your paper will be neater. Question

Answers

Answer:

Law of Syllogism

Step-by-step explanation:

Remember, the Law of Syllogism simply states that if two statements are true, then a third statement that is true can be derived from it. In other words,

(1) If action p results in q , and

(2) If action q results in r.

Then we can derive a third true statement:  that says,

(3) If action p then r.

So in summary,

(1) If you use a pencil (action p), you can erase mistakes (results in q).

(2) If you can erase mistakes (q) your paper will be neater (r).

(3) If you use a pencil (if p) your paper will be neater (then r).

This rightly fits into the law of syllogism.
