If 3% of a number equals 1, find 12% of that number.

Answer:

Step-by-step explanation:

Given the expression sin(9z − 1) = cos(6z + 1), for 0 < z ≤ 90, we are to find z

Note that sin theta = cos(90-thetsa)

sin(9z − 1) = cos(6z + 1)

cos (90 - (9z-1)) = cos(6z + 1)

cos (90 - 9z+1)) = cos(6z + 1)

cos (91-9z) = cos(6z + 1)

Cos will cancel out to have;

91-9z = 6z+1

-9z - 6z = 1-91

-15z = -90

z = 90/15

z = 6

Hence the value of z is 6

Answer:

4th option OR last option

Step-by-step explanation:

Ok so I think it means hexagon not heptagon since I have never heard of heptagon. Just confirm that with your teacher if it is hexagon or heptagon.

Hexagon = 6 sides

This means that it is not second option. Nor it is the third option since it said that it should be more than 6 sides. Now we are left with 1st and 4th option. It also mentioned that all opposite sides should be parallel. Looking at the first option, not all sides are parallel. Some are big and some are small. This remains with the last option which is the 4th option.

Hope this helps, thank you !!

Answer:

$68.20

Step-by-step explanation:

Answer:

85$

Step-by-step explanation:

p = original price

68 = p - 20%p

68 = p - 0.20p

68 = 0.80p

85 = p

The original price was $85.

The original price is 100%. The sales price was 20% off - subtract. So the sale price was 100% - 20% = 80%.

Incase you wanna know how I came up with the 0.80p :)

Step-by-step explanation:

The x = 3 the quadratic equation D) y = 2x² -3x +7 will have maximum value.

The maximum and minimum values of a function:

The maximum and minimum values are the highest and lowest values that a function can reach over a particular domain.

For example, in a quadratic function, the maximum or minimum value is the highest or lowest point on the graph, respectively.

If a function has a maximum value, it means that the function reaches its highest point at a certain value of x.

On the other hand, if a function has a minimum value, it means that the function reaches its lowest point at a certain value of x.

Here we have

(A) y = x²-6x +19  

At x = 3

y = (3)² - 6(3) + 19  

= 9 - 18 + 19 = 10

(B) y = -4x²+24x -21

At x = 3

y = -4 (3)² + 24(3) - 21

= - 4(9) + 72 - 21

= 15

(C) y= -2x² +20x -49

At x = 3

y = - 2 (3)² + 20(3) - 49

= - 18 + 60 - 49

= - 7

(D) y = 2x² -3x +7    

At x = 3

y = 2(3)³ - 3(3) + 7

= 18 - 9 + 7

= 16

Therefore,

The x = 3 the quadratic equation D) y = 2x² -3x +7 will have maximum value.

The Volume of green house is 54 m³

A rectangular prism is a three-dimensional shape that has two at the top and bottom and four are lateral faces.

The volume of a rectangular prism=Length X Width X Height

A company makes a greenhouse that is shaped like a rectangular prism on bottom and a half cylinder on top.

Given;

Base = 3m x 9m

Height of house = 2 m

Find: Volume of green house

Volume of green house = 3m x 9m x 2m

Volume of green house = 54 m³

Step-by-step explanation:

Answer:

Step-by-step explanation:

First you want to mark 2 points. I chose (-2,0) and (2,2), it does not mater what points you chose. Once you have the two points, you need to find the slope. To calculate the slope can be seen below.

Slope (m) = ΔY/ΔX = 1/2 = 0.5

Once you have the slope, which is 0.5, you fill in this equation.

y = mx + b, where m is the slope and b is the y-intercept.

Now filling in given variables, you get this equation.

y = 0.5x + 1

,LCM of 12 and 30 is 60

Answer:

List the first five multiples of 30

The first 5 multiples of 30 are: 0, 30, 60, 90, 120.

What is the lowest common multiple of 12 and 30

for LCM (12,30) we find:

Prime factorization of 12 = 2 × 2 × 3.

Prime factorization of 30 = 2 × 3 × 5.

Using all prime numbers found as often as each occurs most often we take 2 × 2 × 3 × 5 = 60.

Therefore LCM (12,30) = 60
