The probability that Akira will choose apple pie and Paula will choose strawberry cheesecake for dessert is; B: 0.028

We are told that;

There are 6 dessert options menu.

Now, Akira and Paula like all of the choices equally. Thus, probability of selecting any of the 6 menus will be; P(select 1 menu) = 1/6

Thus, probability that they select the preferred menu written in the question is; P(both select 1 menu) = 1/6 * 1/6 = 0.028

Answer:

6 times as many dogs as cats

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

So we know that if we combine all of the dogs and cats, we get 25. We also know that there are 4 times more dogs than cats, so we can call cats x, and dogs 4x.

So 4x + x = 25

5x = 25

x=5

There are 5 cats. Now that we know the number of cats , we just need to multiply that by 4, which is 20 dogs.

1,400 children attend the school

Step-by-step explanation:

If 20% is 280, we can set up a proportion to solve for how many attend the school. I will put the percentages on top and the number of children on the bottom:

-> Please note that a percentage divided by 100 becomes a decimial

[tex]\frac{20}{280}=\frac{100}{x}[/tex]

Cross multiply:

.2 * x = 280 * 1

.2x = 280

Divide both sides of the equation by .2:

1,400 children attend the school

We can check our work by multiplying 1,400 by 0.2:

1,400 * 0.2 = 280 ✓

Answer:

Triangle STU is not similar to Triangle VWU

Step-by-step explanation:

For two triangles to be similar, they both should have the same angle measures. To find out if they have the same angle measures, we have to solve for the unknown angles. Remember, a triangle is worth 180°.

Triangle STU:

Triangle VWU:

As you can see, the angles don't have the same angle measures. Thus, they are not similar.

Answer:

104 degrees

Step-by-step explanation:

RS is a line, so it is 180 degrees.  PO is also a line and point O is touching line RS.  The acute measure is 76 degrees, as shown.  To find the other angle measure for SOP, subtract 76 from 180.  That gives 104 degrees, which is the measure of SOP.

Answer:

"the difference of" means to subtract

Therefore, "the difference of 3 and a number" would be:

3-x

Step-by-step explanation:

The required number is 63 and its 20% will be 12.6.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.

The difference between 3 and the number x of that number is -60.

According to the question, the algebraic form will be as:

⇒ 3 - x = -60

⇒ x = 60 + 3

Apply the addition operation,

⇒ x = 63

So the required number is 63

20% of the number = (20/100) × 63

20% of the number = (0.20) × 63

20% of the number is 12.6.

Therefore, the required number is 63 and its 20% will be 12.6.

The question seems to be incomplete the correct question would be:

The difference between 3 and the number x of that number is -60. What is 20% of that number?

Answer:

f(x) = −6(x+ 1)(x +5)

Step-by-step explanation:

x-intercepts at (−1, 0) and (−5, 0)

so the roots are -1 and -5 (where the graph intersects the x-axis)

this will give us that f(x) = (x- root1)(x-root2) = (x- -1)(x- -5) = (x+1)(x+5)

y-intercept at (0, −30) is telling us that when x= 0 the y = -30

y = a ( x+1)(x+5) , in general

y = a(0+1)(0+5), is the equation if x=0

-30 = a·1·5, we need y= -30 when x= 0

-30 = 5a , divide both sides of the equation by 5

-6 = a

The correct choice is :

f(x) = −6(x+ 1)(x +5)

f(x) = −6(x − 1)(x − 5)

f(x) = −5(x +1)(x +5)

f(x) = −5(x − 1)(x − 5).
