how many nickels she has.

Answer:

I believe it is 65

Step-by-step explanation:

180 - 115 = 65

Answer:

0.75

Step-by-step explanation:

Answer:

98 or option B

Step-by-step explanation:

triangle = 180degrees

9x+2+7x+82=180

16x+84=180

16x=96

x=6

<2 = 7*6 + 7*9+2 which is 98.

Answer :

★Range : Range is the difference of the largest value and the lowest value given in graph in STATICS.

More information :

The formula to find RANGE is :

Range = Maximum value — Minimum value

What is the use of Range :

Range gives us the idea(rough) of the outcome.

Given :

(3,5,12,67,87,13)

Here we can see that the largest value is 87

And the lowest value is 3

Thus,the Range here is ,

= 87 — 3

= 84

Answer:

  D

Step-by-step explanation:

In the second quadrant, ...

  c = 180° -arcsin(24/25) ≈ 106.26°

In the third quadrant, ...

  d = 360° -arccos(-3/4) ≈ 221.41°

Then cos(c+d) = cos(327.67°) ≈ 0.84498

This is a positive irrational number, greater than 21/100, so the only reasonable choice is the last one:

  [tex]\dfrac{21+24\sqrt{7}}{100}\approx 0.84498[/tex]

_____

Perhaps you want to work this out using the trig identities.

  cos(c) = -√(1 -sin(c)²) = -7/25

  sin(d) = -√(1 -cos(d)²) = -(√7)/4

Then the desired cosine is ...

  cos(c+d) = cos(c)cos(d) -sin(c)sin(d)

  cos(c+d) = (-7/25)(-3/4) -(24/25)(-√7/4)

  cos(c+d) = (21 +24√7)/100 . . . . matches choice D

Answer:

5b=2f

Step-by-step explanation:

Priya uses [tex]7\dfrac{1}{2}[/tex] cups of floor to make 3 loaves of banana bread.

Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour.

To find the relation between b and f, the steps are as follows :

[tex]\dfrac{\text{cups of flour}}{\text{loaves of banana bread}}=\dfrac{7 \dfrac{1}{2}}{3}\\\\=\dfrac{\dfrac{15}{2}}{3}\\\\=\dfrac{15}{2}\times \dfrac{1}{3}\\\\=\dfrac{5}{2}[/tex]

It means,

[tex]\dfrac{f}{b}=\dfrac{5}{2}\\\\5b=2f[/tex]

So, the relationship between b and f is "5b=2f".

Answer:

3 batches of cookies

Step-by-step explanation:

Bank. A recipe for one batch of cookies calls for 5 cups of flour and 2 teaspoons of vanilla.

How many batches can you make with 15 cups of flour and 6 teaspoons of vanilla?

We can calculate the batches using either cups of flour or number of teaspoons.

For flour

5 cups of flour = 1 batch of cookies

15 cups of flour = x

Cross Multiply

5x = 15 × 1

x = 15/5

x = 3 batches of cookies

For teaspoons of vanilla

2 teaspoons of vanilla = 1 batch of cookies

6 teaspoons of vanilla = x

Cross Multiply

2x = 6 × 1

x = 6/2

x = 3 batches of cookies.

Hence: you can make 3 batches of cookies with 15 cups of flour and 6 teaspoons of vanilla

Step-by-step explanation:

Answer:

the slope is 4/1 because it's 4x and the y intercept is -4

Answer:

slope: 4

y intercept: -4

Step-by-step explanation:

the equation you're given is in y = mx + b format

the "b" in the equation is the y intercept

the x and y are the variables

and the "m" is the slope

so in this case, the "m" would be 4 because it is the number right next to x

the -4 would be the "b" in this because it is after the "y=" and does not have a variable

Answer:

40

Step-by-step explanation:

remember PEMDAS

our equation looks like tihs: [tex]\frac{80}{(6+(3-5)*2)}[/tex]

1. parentheses: in the denominator we have a parentese inside of another parenthese, so start with the inside first: (3-5) = -2.

so now our equation looks liek this [tex]\frac{80}{(6-2 *2)}[/tex]

now we have a mini PEMDAS situation within the parentheses: multiplication comes before addition/subtraction, so multiply -2*2 = -4, so now your equation looks like this: [tex]\frac{80}{(6-4)}[/tex]

6-4 =2: so now we're done with parentheses part of PEMDAS, the only thing left is dividing 80/2 which equals 40.

Answer:

Step-by-step explanation:

We know that to find the area of a rectangle its length x width so to solve your problem you would do x+ 2 + 2x + 3 = 91 then solve it

add xs together x3 + 2 + 3 = 91

add other values x3 + 5 = 91

                                  -5      -5

                                   x3 = 86

the divide by 3

x = 26.667

Then to finish the question replace x with 26.667 and do the math

2(26.667) + 3 = 56.334

26.667 + 2 = 28.667

Width: 56.334

Length: 28.667

The ratio 1:2 and 2:7 are not equivalent to each other.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

To get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator. Thus, a = px, b = qx

We are given the ratio as; 1:2 and 2:7

To find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7. ...

Next, multiply both the numerator and denominator

1/7 x 2 = 2/14,

or 2:14,

Now multiply the numerator and denominator

1/7 x3 =  3/21,

or 3:21.

Therefore, the ratio are not equivalent to each other.

Answer:

$14,000

Step-by-step explanation:

First, convert the percentage to a decimal and get 0.07. Multiply this by 200,000 and get 14,000. So 7% of 200,000 is 14,000.

Answer:

Coordinates of W' → (3, 3)

Coordinates of U' → (5, 4)

Step-by-step explanation:

If the given figure is dilated about a point (4, 3) by a scale factor k = [tex]\frac{1}{2}[/tex]

Then the length of each side will get reduced to half of its original length.

(As in the figure attached)

Scale factor = [tex]\frac{\text{Side length of image}}{\text{Side length of preimage}}[/tex]

[tex]\frac{1}{2}=\frac{V'U'}{VU}[/tex]

V'U' = [tex]\frac{1}{2}(VU)[/tex]

Now from the graph,

Coordinates of W' → (3, 3)

Coordinates of U' → (5, 4)

Answer:

Answer:

what is the full question

Answer:

0.75 cents

Step-by-step explanation:

You take...

$2.25 and subtract $1.50 to get 0.75 cents

In-depth...

Start off with taking a dollar away...

2.25 - 1.00 = 1.25

Then take off 0.50 cents...

We know that 0.50 cents are two 0.25 cents

So, we take off one 0.25 cent

1.25 - 25 = 1.00

Then the next 0.25 cents

*Remember: twenty-five (.25), fifty (.50), seventy-five (.75), a dollar (1.00)

<--- it is just adding 25 each time

If we subtract 0.25 cents from a dollar we get...

0.75 cents

Answer:

0.75

Step-by-step explanation:

2.25-1.50=0.75

Answer

Step-by-step explanation:

You would require the table with the number of males and females who prefer either pink or yellow lemonade at the state fair.

                     Pink Lemonade         Yellow Lemonade       TOTAL

Male                    156                                104                          260

Female                  72                               48                          120

TOTAL                 228                               152                         380

P(pink lemonade | female) = 72 / (48 + 72) = 72 / 120 = 0.6

P(pink lemonade) = (156 + 72) / (156 + 72 + 104 + 48) = 228 / 380 = 0.6

Therefore, The event "prefers pink lemonade" and "female" are independent because P(pink lemonade | female) = P(pink lemonade) = 0.6

Independents events are events that can happen independently on their own. Events A and B are independent if P(A|B) = P(A).

The "prefer pink" event and "female" event are independent because [tex]P(P|F) = P(P) = 0.6[/tex]

To do this, we make the following representations:

[tex]P \to[/tex] Pink Lemonade

[tex]Y \to[/tex] Yellow Lemonade

[tex]M \to[/tex] Male

[tex]F \to[/tex] Female

The "prefer pink" event and "female" event are independent if:

[tex]P(P|F) = P(P)[/tex]

[tex]P(P|F) \to[/tex] the probability that a selected person prefers pink provided that the person is female

[tex]P(P) \to[/tex] the probability that a selected person is female

P(P| F) is calculated as:

[tex]P(P| F) = \frac{n(P\ n\ F)}{n(F)}[/tex]

i.e. the number of females who prefers pink divided by the number of females

From the table, we have:

[tex]n(P\ n\ F) = 72[/tex]

[tex]n(F) = 72 + 48 =120[/tex]

So, the probability is:

[tex]P(P| F) = \frac{72}{120}[/tex]

[tex]P(P| F) = 0.6[/tex]

[tex]P(P)[/tex] is calculated as:

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

i.e. the all people who prefer pink divided by total number of people

From the table, we have:

[tex]n(P) = 156 + 72 = 228[/tex]

[tex]Total = 156 + 72 + 104 + 48 = 380[/tex]

So, the probability is:

[tex]P(P) = \frac{228}{380}[/tex]

[tex]P(P) = 0.6[/tex]

Recall that:

The "prefer pink" event and "female" event are independent if:

[tex]P(P|F) = P(P)[/tex]

And we have:

[tex]P(P| F) = 0.6[/tex]

[tex]P(P) = 0.6[/tex]

Hence, the events are independent because:

[tex]P(P|F) = P(P) = 0.6[/tex]

Option (a) is correct
