75% is equal to 3/4 so 3*16 =48/4 which leaves you with 12
2. 25% is equal to 1/4 so 24/4 leaves you with 6 making that the amount

1. To get the result we have to find 75% of 16.
75%=0.75
0.75*16=12 - you should shade 12 triangles.
2. Similar situation
25%=0.25
0.25*24=6 - you should shade 6 triangles

Find the dimensions of the rectangular corral producing the greatest enclosed area given 320 feet of fencing. (Assume that the l
jenyasd209 [6]

Answer:

The dimensions of the rectangular corral producing the greatest enclosed area  is a square of 80 ft x 80 ft

Step-by-step explanation:

Let

x -----> the length of the rectangular corral in feet

y -----> the width of the rectangular corral in feet

we know that

The area of the rectangular corral is equal to

A=xy -----> equation A

The perimeter of the rectangular corral is equal to

P=2(x+y)

P=320\ ft

so

320=2(x+y)

Simplify

160=(x+y)

y=160-x -----> equation B

substitute equation B in equation A

A=x(160-x)

A=-x^2+160x

This is a vertical parabola open downward

The vertex is a maximum

The x-coordinate of the vertex represent the length for the maximum area

The y-coordinate of the vertex represent the maximum area

Convert the quadratic equation in vertex form

A=-x^2+160x

Factor -1

A=-(x^2-160x)

Complete the square

A=-(x^2-160x+80^2)+80^2

A=-(x^2-160x+80^2)+6,400

Rewrite as perfect squares

A=-(x-80)^2+6,400

The vertex is the point (80,6,400)

so

x=80\ ft

The maximum area is 6,400 ft^2

<em>Find the value of y</em>

y=160-x  ----> y=160-80=80\ ft

therefore

The dimensions of the rectangular corral producing the greatest enclosed area  is a square of 80 ft x 80 ft

Olivia bought some granola bars and spent at least $6.24. Write and solve an equality to find the number of granola bars she bou
marishachu [46]

Answer:

n ≥ 6.24/x

Step-by-step explanation:

Given that :

Amount spent is atleast $6.24

Let price spent = p

p ≥ $6.24

If cost of granola bar = x

The number of granola bars, n purchased will be :

n ≥ 6.24/x

Since cost of granola bar isn't given, we represent it as x.

Consider a Triangle ABC like the one below. Suppose that C = 98, A = 74, and b = 11 (figure is not drawn to scale.) solve the tr
Degger [83]

Answer:

A=73.8\°

B=8.2\°

c=76.3\ units

Step-by-step explanation:

step 1

Find the measure of side c

Applying the law of cosines

c^{2}= a^{2}+b^{2}-2(a)(b)cos(C)

substitute the given values

c^{2}= 74^{2}+11^{2}-2(74)(11)cos(98\°)

c^{2}=5,823.5738

c=76.3\ units

step 2

Find the measure of angle A

Applying the law of sine

\frac{a}{sin(A)}=\frac{c}{sin(C)}

substitute the given values

\frac{74}{sin(A)}=\frac{76.3}{sin(98\°)}

sin(A)=(74)sin(98\°)/76.3

A=arcsin((74)sin(98\°)/76.3)

A=73.8\°

step 3

Find the measure of angle B

we know that

The sum of the internal angles of a triangle must be equal to 180 degrees

so

A+B+C=180\°

substitute the given values

73.8\°+B+98\°=180\°

171.8\°+B=180\°

B=180\°-171.8\°=8.2\°

irina1246 [14]

Answer:

30 students

Step-by-step explanation:

80%  of  N   =   24            where N  is  the total number of students

So

.80 N   =  24

N =  24 /  .80     =      30
