Find the rate of change represented on the graph- please help ! first answer will get brainliest

a) 3
b) 1/3
c) -3
d) -1/3

Step-by-step explanation:

Area of the square = a²

= 20²

= 400cm²

Area of the circle = πr²

= 22/7 × 9²

= 22/7 × 81

= 254.57cm²

Area of the shaded region = Area of the square - Area of the circle

= 400cm² - 254.57cm²

= 145.43cm²

Step-by-step explanation:

2a - 7 - 6a = 9

- 4a - 7 = 9

- 4a = 16

a = -4

Answer:

[tex]4^{21}[/tex]

Step-by-step explanation:

[tex]\frac{4^{12}}{4^{-9}}\\[/tex]

Given 4 = a

From the properties of exponents for the example...

[tex]\frac{a^4}{a^{-2}} = \frac{a*a*a*a}{\frac{1}{a^2} } = (a*a*a*a)*a^2 = a^4 * a^2 = a^{4+2} = a^6[/tex]

Therefore, the answer is....

[tex]4^{12}*4^{9} = 4^{12+9} = 4^{21}[/tex]

Answer:

1. 50%

2.[tex]\frac{5}{6}[/tex]

Step-by-step explanation:

1. The way to approach the probability of rolling an odd number is to start with the total numbers. Therefore, each dice has three even sides and three odd sides. Mathematically - 50% chance of landing on the odd number.

2. You have 'P' which represents probability. "N" which is the given ratio of the number of outcome. (NP) total number of the possible outcome.

P = N / NP

Dice has 6 faces. I.E. 1,2,3,4,5,6

= 6

NP, therefore, is the total number of possible outcome.

Faces less than 6. (1,2,4, and 5)

N = 5

P = N / NP = [tex]\frac{5}{6}[/tex] ; it can't be reduced.

Answer:

10

Step-by-step explanation:

To find the number, divide 3 by 0.3

3/0.3

= 10

So, 30% of 10 is 3.

Now , For 12n to end with 0, it should have 2 as well as 5 in its Prime factors to end with 0, Also to end with 5 , it requires at least a single multiple of 5 in its Prime Factors, So 12n cannot end with the digit 0 or 5.

Answer:

[tex]5\dfrac{1}{2}\ \text{kg}[/tex]

Step-by-step explanation:

Plant food used on strawberry plants is

[tex]1\dfrac{2}{3}\ \text{kg}=\dfrac{5}{3}\ \text{kg}[/tex]

Plant food used on tomato plants is

[tex]\dfrac{1}{4}\ \text{kg}[/tex]

Feeding the strawberry plants two times means

[tex]\dfrac{5}{3}+2\times\dfrac{5}{3}=\dfrac{5}{3}+\dfrac{10}{3}\\ =\dfrac{15}{3}=5\ \text{kg}[/tex]

Feeding the tomato plants one more time means

[tex]\dfrac{1}{4}+\dfrac{1}{4}=\dfrac{2}{4}\\ =\dfrac{1}{2}\ \text{kg}[/tex]

The plant food he will need is [tex]5+\dfrac{1}{2}=5\dfrac{1}{2}\ \text{kg}[/tex]

Answer:

(7, - 1)

Step-by-step explanation:

Answer:

n5 + 17

Step-by-step explanation:

They're asking for a pattern.

17 + 5 = 22

22 + 5 = 27

27 + 5 = 32

So it starts at 17 and increases by five each time.

The nth term increases by 5 each time and starts at 17. That means the nth term is multiplied by 5 each time, but you have to add 17 because that's where the pattern starts.

n5 + 17

Given:

Cost of adult's ticket = $15

Cost of  children's  ticket = $8

Total tickets = 725

Total sales = $8775

To find:

The number of each type of ticket were sold.

Solution:

Let x be the number of adult tickets and y be the number of children's ticket.

Total tickets : [tex]x+y=725[/tex]         ...(i)

Total sales : [tex]15x+18y=8775[/tex]           ...(ii)

Multiply equation (i) by 15.

[tex]15x+15y=10875[/tex]         ...(iii)

Subtract (iii) from (ii),

[tex]15x+18y-15x-15y=8775-10875[/tex]

[tex]3x=-2100[/tex]

[tex]x=-700[/tex]

Putting x=-700 in (i), we get

[tex]-700+y=725[/tex]

[tex]y=725+700[/tex]

[tex]y=1425[/tex]

Therefore, the number of adult tickets is -700 and number of child tickets is 1425.

Note: The number of tickets cannot be negative. So, there must be some error in the question.

Answer:

JK = 50; IJ = 25√3

Step-by-step explanation:

HAVE: sin ∠J = sin 30° = [tex]\frac{IK}{JK}[/tex]

=> [tex]\frac{IK}{JK}=\frac{25}{JK}=\frac{1}{2}=> JK = 25.2 = 50[/tex]

cos ∠J = cos 30° = [tex]\frac{IJ}{JK}[/tex]

=> [tex]\frac{IJ}{JK}=\frac{IJ}{50}=\frac{\sqrt{3} }{2} => IJ = \frac{\sqrt{3} }{2}.50=25\sqrt{3}[/tex]

Answer:

two triangles that are similar, that have equal angles

Answer:

the triangle which has same shape,sixe and angles is called similar triangle

Step-by-step explanation:

180 - 34 = 146

one angle is a right angle, angle across it is 146, 360 - 90 - 146 = 124

divide that by two to get the measures of the remaining two angles (62 degrees)

180 - 62 = x

118 = x

Answer:

You cannot simplify 7/15 to a smaller fraction. But you could divide 7 by 15 to get a decimal.

Step-by-step explanation:

Answer:

you can't simplify the number 7

Answer:Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.

Step-by-step explanation:The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.

Answer:

Mikaya and Olivia are correct to be suspicious

Step-by-step explanation:

Sum of the angles of a triangle is always 180

But, The sum of all angles of the triangle that Zuri solved = 93 + 63 + 36 = 192 ≠ 180

So, Zuri is wrong
