Answer:

RS 99

Step-by-step explanation:

%p = p/cp ×100

22 = p/450 × 100

22 = 100p/450

cross multiply

22 × 450 =100p

9900 = 100p

100p =9900

p = 9900/100

p = 99

Answer:

B) 9

Step-by-step explanation:

Because there's a square between the 2 angles, that means these angles are complementary (angles that add up to 90°). So:

5x - 9 + 6x = 90

11x - 9 = 90

11x = 90 + 9

11x = 99

x = 9

Answer:

B.9

Step-by-step explanation:

The way to solve this is by noticing that these angles are complementary(they add up to 90 degrees). So you add the equations together and equal them to 90. 5x-9+6x=90.Then you solve to find that x=9.

Given: -1/2 x > 6

-1/2 x > 6

x > -6×2

x > -12

Answer:

SA= 3603.84cm^2

Step-by-step explanation:

the Surface Area SA is the total area of the sides and the base.

The area of the base= 32*32= 1024cm^2

the area of one of the sides = slant height of pyramid * base edge/2

the slant height l of the pyramid

l= sqrt(16^2+37^2) = 40.31cm

area of the side =( 40.31*32)/2 =644.96cm^2

there are 4 sides so the area of the sides are

4* 644.96=

addig the area of the base we get the Surface Area SA of the pyramid

SA = 2579.84 + 1024 = 3603.84cm^2

The answers is 369 and 577... good luck. ♥️♥️♥️

Answer:

116y = 96.28

----      ---------

116        116

y = 0.83--------

Answer:

0.83-------

Step-by-step explanation:

Answer:

y = -4.9/5.4x - 1.17

Step-by-step explanation:

First let's convert the equation to standard form of y = mx + b.

4.9x + 5.4y = 3

Subtract 4.9x from both sides.

5.4y = -4.9x + 3

Divide each term by 5.4.

y = -4.9/5.4x + 0.56

If two lines are parallel to each other, they have the same slope slopes.

The first line is y = -4.9/5.4x + 0.56. Its slope is -4.9/5.4. A line parallel/perpendicular to this one will also have a slope of -4.9/5.4.

Plug this value (-4.9/5.4) into your standard point-slope equation of y = mx + b.

y = -4.9/5.4x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (-3.6, 2.1). Plug in the x and y values into the x and y of the standard equation.

2.1 = -4.9/5.4(-3.6) + b

To find b, multiply the slope and the input of x (-3.6)

2.1 = 3.27 + b

Now, subtract 3.27 from both sides to isolate b.

-1.17 = b

Plug this into your standard equation.

y = -4.9/5.4x - 1.17

This equation is parallel/perpendicular to your given equation (y = -4.9/5.4x + 0.56) and contains point (-3.6, 2.1)

Hope this helps!

Answer:

1/8

Step-by-step explanation:

9/16 * 4/18

Rewriting

9/18 * 4/16

9/18 = 1/2   and 4/16 = 1/4

1/2 * 1/4

Answer:

210 * 1.1 = 231

48*1.1 = 52.8

Step-by-step explanation:

Answer:

the first one x is 6 and y is 11

the second one y is 5 and x is 3

the third one x is 15 and y is 17

the fourth one y is 15 and x is -12

Step-by-step explanation:

to find the first answer you have to use the actual equation given and substitute the value of x in it

y=-2(-6)/3+7

=12/3+7

=4+7

=11

the second one is quite different because the value of y has been given and not x so you have to substitute the value of y in the equation which is 5

5=-2x/3+7

5-7=-2x/3

-2/1=-2x/3

-2x/-2=-6/-2

x=3

for the third one you have to solve it like the first one

y=-2(15)/3+7

=10+7

=17

the fourth one is similar to the second one

15=-2x/3+7

15-7=2x/3

8=2x/3

-2x/-2=24/-2

x=-12

Answer:

  B.  3x² +2 = 0

Step-by-step explanation:

The equation of A has a couple of real roots. We're pretty sure there are complex numbers that will satisfy this equation, but we don't know how to find them. (We suspect a typo, and that the equation is supposed to be 2x² +1 = 7x, which has only real roots.)

__

The equation of B can be rewritten as ...

  x² = -2/3

This will have complex roots.

__

The discriminants of both equations C and D are positive, so those have only real roots.

Answer:

Step-by-step explanation:

90/100 * x = 15750

0.9 x = 15750

x = 15750/0.9

x = 17500

Now check this by taking 10% off. Do you get 15750?

Let's see

10/100 of 17500 = 1750

Subtract that from 17500

17500 - 1750 = 15750 which is exactly what you should get.

Answer:

Another example of a number who's square root is greater than the number is  [tex]\sqrt{0.49}[/tex] which is 0.7

Step-by-step explanation:

This square root is larger than the number because it is a decimal. When you multiply a decimal by a decimal, the decimal point becomes greater. For example: 0.7 multiplied by 0.7 equals 0.49 which has 2 decimal places, while 0.7 only has one.

Step-by-step explanation:

The probability that Ryan will pick a jelly bean that has a flavor he likes is 0.7

"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

[tex]P(A)=\frac{n(A)}{n(S)}[/tex]

where, [tex]n(A)[/tex] is the number of favorable outcomes

is [tex]n(S)[/tex] the total number of events in the sample space.

From given data:

Ryan received a box of jelly beans with

Grape - 16

Licorice - 10

Cherry - 12

Lemon - 14

Lime - 8

So, there are total 16 + 10 + 12 + 14 + 8 = 60 jelly beans.

Ryan does not like licorice or lime.

⇒ 10 + 8 = 18 jelly beans he does not like.

This means, he likes 60 - 18 = 42 jelly beans.

Now, we find the probability of jelly beans that has a flavor he likes.

⇒ P = (number of grape, cherry, lemon jelly beans) / (total number of jelly beans)

⇒ [tex]P=\frac{42}{60}[/tex]

⇒ [tex]\bold{0.7}[/tex]

Therefore, the probability that Ryan will pick a jelly bean from the full box that has a flavor he does like is 0.7

#SPJ2

Answer:  2 distinct complex solutions (ie non real solutions).

Work Shown:

The given equation is in the form ax^2+bx+c = 0, so

a = 1, b = 3, c = 8

Plug those into the formula below to find the discriminant

D = b^2 - 4ac

D = 3^2 - 4(1)(8)

D = -23

The discriminant is negative, so we get two nonreal solutions. The two solutions are complex numbers in the form a+bi, where a & b are real numbers and [tex]i = \sqrt{-1}[/tex]. The two solutions are different from one another.

Answer:

Discriminant: -23

Number of real roots: 0

Step-by-step explanation:

For a quadratic in standard form [tex]ax^2+bx+c[/tex], the discriminant is given by [tex]b^2-4ac[/tex].

In [tex]x^2+3x+8[/tex], assign:

The discriminant is therefore:

[tex]3^2-4(1)(8)=9-32=\boxed{-23}[/tex]

For any quadratic:

Since the quadratic in the question has a discriminant less than 0, there are no real solutions to this quadratic.
