Answer:

42%

Step-by-step explanation:

The first step is to calculate the difference in the number of fishes from the beginning of the day to the end of the day.

90 -52

= 38 fishes

Therefore the percent decrease can be calculated as follows

= 38/90 × 100

= 0.422 × 100

= 42.2 %

= 42% ( to the nearest cent)

your answer is:

Answer:

1. 9.8 cm

2. 44.5 cm^2

Step-by-step explanation:

1. To find the length of arc AB, we use the formula for the length of an arc

Mathematically, that will be;

theta/360 * 2 * pi * r

theta is the central angle which is 51

r is the radius which is 10 cm

So we have

51/360 * 2 * 22/7 * 10 = 8.9 cm

2. The area of the sector

we use the formula for the area of a sector here,

That is;

theta/360 * pi * r^2

51/360 * 22/7 * 10 * 10

= 44.5 cm^2

Answer:

h=1.3056 m

Step-by-step explanation:

L=2.5m

w=L(1 + 9/16)

w=2.5(1 + 9/16)=[tex]\frac{125}{32}[/tex] m=3 [tex]\frac{29}{32}[/tex]m

v=Lwh

12.75m³=(2.5m)([tex]\frac{125}{32}[/tex]m)h

12.75m³=(9.765625m²)h

[tex]\frac{12.75m^{3} }{9.765625m^{2} }[/tex]=h

h=1.3056 m

Answer:

3 3/16

Step-by-step explanation:

If:

Length= 2 1/2

Width=2 1/2 divided by 1 9/16= 1 3/5

Volume=12 3/4

So then, 2 1/2 times 1 3/5=4

12 3/4 divided by 4= 3 3/16

We want to solve the given system of equations graphically

The estimated solution that we will get is (0, -2)

The given system of equations is:

y = 2x - 2

y = -35x + 1

To solve it graphically, we need to graph both lines on the same coordinate axis, and see where the lines intersect.

The graph can be seen below, there we can see that the lines intersect near the point (0, -2)

Note that this does not coincide with any of the given solutions, which means that one of the two lines must be written incorrectly.

Answer:

Lot 4 since 61.5% is the highest percentage of blue cars of all lots.

Step-by-step explanation:

Find the percentage that each number of blue cars is in its parking lot.

percent = part/whole * 100%

15 of the 36 cars in lot 1 were blue

15/36 * 100% = 41.667%

43 of the 92 cars in lot 2 were blue

43/92 * 100% = 46.739%

12 of the 30 cars in lot 3 were blue

12/30 * 100% = 40%

32 of the 52 cars in lot 4 were blue

32/52 * 100% = 61.538%

Answer: Lot 4 since 61.5% is the highest percentage of blue cars of all lots.

Answer:

Parking Lot 4

Step-by-step explanation:

15÷36 x 100 = 41.666%

43÷ 92 x 100 = 46.739%

12 ÷ 30 x 100 = 40%

32÷ 52 x 100 = 61%

61% is the largest percentage out of all of them, therefore Parking Lot 4 ( 32 out the 52 cars) is the Parking Lot that has the greatest percentage of blue cars!

Answer:

x = 0, -4 and -3.

Step-by-step explanation:

The given expression is "3x to the power of 3 + 21x squared + 36x = 0".

We can write this expression as follows :

[tex]3x^3+21x^2+36x=0[/tex]

Taking 3x common.

[tex]3x(x^2+7x+12)=0\\\\3x=0\ \text{and}\ (x^2+7x+12)=0[/tex]

x = 3

[tex]x^2+7x+12=0\\\\x^2+3x+4x+12=0\\\\x(x+3)+4(x+3)=0\\\\(x+4)(x+3)=0\\\\x=-4,-3[/tex]

Hence, the solution of the given quadratic equation are x = 0, -4 and -3.

-1/4 is the only correct solution to the equation represented by the graph.

Answer:

m∠4 = 55°

Step-by-step explanation:

From the figure attached,

m∠DBC = m∠BCA + m∠BAC [Exterior angle of a triangle equals the sum of the remote interior angles]

m∠4 = 30° + 25° = 55°

Therefore, m∠4 = 55° will be the answer.

Step-by-step explanation:

An equation of the line that passes through (-1,4) and is perpendicular to the line given in the graph is y=3x+7.

The coordinates from the line on the graph is (-3, 4) and (3, 2).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

Now, slope =(2-4)/(3+3)

= -2/6

= -1/3

Substitute m=-1/3 and (x, y)=(-3, 4) in y=mx+c, we get

4=-1/3 (-3)+c

⇒ c=3

The slope of a line perpendicular to given line is m1=-1/m2

So, slope =3

An equation of the line that passes through (-1,4)

Now, 4=3(-1)+c

c=7

Put m=3 and c=7 in y=mx+c, we get

y=3x+7

Therefore, an equation of the line that passes through (-1,4) and is perpendicular to the line given in the graph is y=3x+7.
