Step-by-step explanation:

Answer:

A≈10.83cm²

Step-by-step explanation:

Unit Conversion:

P=15cm

Using the formulas

A=3

4a2

P=3a

Solving forA

A=3P2

36=3·152

36≈10.82532cm²

Answer:

10.8 cm^2 to nearest tenth.

Step-by-step explanation:

You can use Hero's formula to do this:

Area = √[s(s-a)(s-b)(s-c)]   where s = semi-perimeter,  a b and c are the lengths of the 3 sides,

Here s = 15/2 = 7.5 and a, b and c = 5.

area = √(7.5 * 2.5 * 2.5 * 2.5)

= √117.1875

= 10.8253.

Another method would be to use trigonometry

h = 5 sin 60 and 1/2 * base = 1/2 * 5 = 2.5

So area = 5 sin60 * 2.5 = 10.8253,

Answer:

[tex]\frac{96}{91}[/tex] or 51.69

Step-by-step explanation:

[tex]\frac{-6}{13}[/tex] x reciprocal of [tex]\frac{-7}{16}[/tex]

Reciprocal of [tex]\frac{-7}{16}[/tex] is [tex]\frac{-16}{7}[/tex]

So, the equation would be:-

[tex]\frac{-6}{13}[/tex] x [tex]\frac{-16}{7}[/tex]

= [tex]\frac{96}{91}[/tex]

The product would be [tex]\frac{96}{91}[/tex].

Simplified form of this is 51.692

Answer:

f(6)=42

Step-by-step explanation:

We know that the equaiton is f(x)=2x+3(x+4). So that means when it is f(6), we plug in 6 into all of the x. Therefore, the equation will be f(6)=2(6)+3(6+4). We combine like terms to get f(6)=12+3(10). We do 3x10 which is equal to 30. f(6)=30+12. 30+12=42. f(6)=42. Therefore, f(6)=42.

Answer: 47

Step-by-step explanation:

That just means replace the x’s with 6 in the equation. So 2*6+3(6+4)+5. 6+4 is 10, 2*6 is 12. So the equation is now 12+3(10)+5. 3*10 is 30. 12+30+5=47.

Answer: 32

Step-by-step explanation:

When given a question where there is a distinct set of items to choose from, the total number of configurations is equal to 2 to the power of number of different choices. Since there are five different choices, the number of different sundaes is equal to 2^5 or 32 sundaes.

Answer:

5 millennia

Step-by-step explanation:

The simplest way to get the answer is that a millennium is 1,000 years and since you mentioned there are 4 millennia in 4,000 years, you would need to divide 5,000 by 1,000.  Your answer should be 5 millennia.

Answer:

(7, 4)

Step-by-step explanation:

The solution to the system of the 2 equations represented on the graph by the two lines is the c

x and y coordinates of the point where the two lines intersect.

They intersect at when x = 7, y = 4.

Therefore, the solution to the system of equations would be (7, 4).

Answer:

y = -2/3x + 4

y+1 = -4/6(x + 5)

Step-by-step explanation:

y = -2/3x + 4

y+1 = -4/6(x + 5)       *-4/6 is equal to -2/3

perpendicular lines have slope that are opposite signs and reciprocals

the slope of the original line in this problem is 3/2 so any line with a slope of -2/3 is perpendicular to it

Answer:

it will be any equation with a slope that is the opposite reciprocal of 3/2 or it's equivalent. So in this case, -2/3. be sure to check the negative does and see if other slopes are the same as -2/3 but in a different form.

Answer:

C. III only

Step-by-step explanation:

a quadratic function means that as the maximum power in its arguments it is squaring 1 or more items.

so, let's look at the tables.

table I shows the powers of 2. y = 2^x

2^0 = 1

2^1 = 2

2^2 = 4

2^3 = 8

so, it is not saying anything in general.

table II shows an "identity" equation. y = x

0 = 0

1 = 1

2 = 2

3 = 3

this does not square anything.

table III shows then finally a square equation. y = x^2

0^2 = 0

1^2 = 1

2^2 ≈ 4

3^2 = 9

hurray !

The probability that a dart thrown at random within the dartboard will hit the bull's eye is 14.1%

Step-by-step explanation:

[tex]The probability is found by dividing the area of the bull's eye by the total area of the dart board:\[\large P(bull's\ eye)=\frac{\pi\ 6^{2}}{\pi\ 16^{2}}=\frac{36}{256}=0.1406\]Therefore your answer of 14.1% is close.[/tex]

#SPJ2

Answer:

$10

Step-by-step explanation:

Unit rate

$8/4cup = $2/cup

Therefor

5 cups * $2/cup = $10

Answer:18$

Step-by-step explanation:first you wanna see the rate 8 dollars for 4 cups so 8/4 gives you 2.The rate is 2 dollars per cup.

So now we have to find how much 5 cups is worth.Since we know how much each lemonade cost we just have to plug it all in!So 5*2.Is 10 and we also made 8 bucks from the first 4 cups.

Now that we know that we sold 8$ the first time and 10$ the second we add them all up to give you “18$“total

Answer:

A = 43°

b = 26.8

c = 36.7

Step-by-step explanation:

✔️Find A:

A + 90° + 47° = 180° (sum of triangle theorem)

A + 137° = 180°

Subtract 137° from each side

A = 180° - 137°

A = 43°

✔️Find b and c by applying trig functions:

Reference angle = 47°

Opposite = b

Hypotenuse = c

Adjacent = 25

To find b, apply TOA:

Tan 47° = Opp/Hyp

Tan 47 = b/25

25*Tan 47 = b

26.8092178 = b

b = 26.8 (nearest tenth)

To find c, apply CAH:

Cos 47° = Adj/Hyp

Cos 47° = 25/c

c*Cos 47° = 25

c = 25/Cos 47°

c = 36.6569796

c = 36.7 (nearest tenth)
