A bowl contains blueberries and strawberries. There are a total of 20 berries in the bowl. The ratio of blueberries to strawberries is 4 : 1. How many of each berry are in the bowl?

Answers

Answer:

4 strawberries

16 blueberries

Step-by-step explanation:

Given that:

Berries in bowl = strawberries and blueberries

Total number of berries = 20

Ratio of blueberries to strawberries = 4 : 1

Number of each berries in bowl:

Total ratio = (4 +1) = 5

Number of Blueberries :

(Ratio of blueberries / total ratio) * number of berries

(4/5) * 20

= 16 blueberries

Number of strawberries :

(Ratio of strawberries / total ratio) * number of berries

(1/5) * 20

= 4 strawberries

Answers

Answer:

After solving the compound inequality [tex]1.5x-1>6.5 \ or \ 7x+3<-25[/tex] we get [tex]\mathbf{x>5 \ or \ x<-4}[/tex]

Option B is correct.

Step-by-step explanation:

We are given compound inequality: [tex]1.5x-1>6.5 \ or \ 7x+3<-25[/tex]

We will first solve the inequalities to find the value of x, then will draw the graph.

[tex]1.5x-1>6.5 \ or \ 7x+3<-25\\1.5x-1+1>6.5+1 \ or \ 7x+3-3<-25-3\\1.5x>7.5 \ or \ 7x<-28\\x>\frac{7.5}{1.5} \ or \ x<\frac{-28}{7}\\x>5 \ or \ x< -4[/tex]

So, after solving the compound inequality [tex]1.5x-1>6.5 \ or \ 7x+3<-25[/tex] we get [tex]\mathbf{x>5 \ or \ x<-4}[/tex]

Now, the number line will be as shown in figure.

The description as given in options is:

A number line goes from negative 10 to positive 10. An open circle appears at negative 4 and positive 5. The number line is shaded from negative 4 toward negative 10. The number line is also shaded from positive 5 toward positive 10.

Determine if the ordered pair (-5, -1) is a
solution of 2x - y =-11.

Answers

No, when you plug is -5 for x and -1 for why, it ends up being -9 not -11. (-5,-1) is not a solution.

Answer:(-5,-1) is not an ordered pair

Step-by-step explanation:

the ordered pair (-5,-1) is directly related to the variables (x,y) making -5=x and -1=y

so to figure out if the ordered pair is a solution you just plug in the number into their respective variable.

so the equation then becomes 2 (-5) - (-1) = -11

once you solve for the left part of the equation you are then left with -9 = -11 which we know is false.

help & not just comment for points thank youu

Answers

Answer:

For me it looks like downward and upward parabola.

The graph is periodical meaning that it repeats itself after some point. This is because the motion of the wheel makes the car move up and then come back down again. Each local min point is likely where the riders get on the ride, since its closest to the ground. Each local max point is the highest point on the graph indicating when the car is at the top of the wheel.

Let's say that the vertical distance from the lowest point to the highest point is 50 feet, just as an example. This would mean the amplitude is half that at 50/2 = 25 feet. The amplitude represents the vertical distance from the center line to either the highest or lowest point.

The period describes how long each cycle takes. For instance, if it takes 60 seconds for a specific car to go from the bottom position, loop around, and then come back to the bottom position, then the period is 60 seconds. The frequency is simply 1 over the period. Though the frequency may not be used as much.

So overall this curve is likely a sine or cosine curve (depending on the phase shift of course). Also there's a vertical shift as well. Because we don't have any numbers to work with, the actual sine or cosine function cannot be determined.

what is the value of the ratio 4:5

Answers

Answer:

You might need to be more specific, it could be 4 puppies to 5 dogs, or 4 apples to 5 oranges or 4 cups of flour to 5 cups of flour.

Step-by-step explanation:

The value of 4:5 is 4 for every 5 like 4 cups of sugar for every 5 cups of flour

The simplified form of ratio 4:5 is 0.8. The ratio is given in the form of p/q.

What is the ratio?

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.

It is given that the ratio is 4:5.

To convert mixed numbers into improper fractions, when A is the numerator or B is the denominator,

If either A or B is a decimal number, multiply both of their values by the same factor of 10, which will remove all decimal places.

If one value is a whole number and the other is a fraction, you should try to reduce the fraction to a whole number or convert the whole number to a fraction by giving it a denominator of 1.

= 4 / 5

We have to apply the division operation in which we have to divide the number 4 by 5 in order to obtain the improper fraction values as,

=0.8

Thus, the simplified form of ratio 4:5 is 0.8. The ratio is given in the form of p/q.

If you ate 1/5 of the desert served at

Answers

20% of food is eater. 1 divided by 5 is 0.2. You move the decimal 2 unites which would be 20.

Answer:

20%

Step-by-step explanation:

so to become a percentage, you should multiply by 100% (which is basically 100/100 but don't multiply the bottom instead you write a percent sign)

So 1/5*100/100 without multiplying the bottom is:

100/5%

100 divided by 5 is 20. There you go! And you can use a calculator if that is easier for you. All you do is 1/5 which is .20 and your answer is 20%! Hope this helps!

What is Distance Formula?

In a Cartesian plane there are two points P(a, b) and Q(c, d) then the distance between two points

PQ = √(c- a)² + (d- b)²

We have the coordinates F(2, 2) O(5, -2) U(9, 1) and R(6, 5).

Now using Distance Formula

FO = √(-2 - 2)² + (5- 2)² = √16 + 9 = √25 = 5 unit

OU = √(1 + 2)² + (9-5)² = √9 + 16 = √25 =5  unit

UR = 5 unit

RF = 5 unit

and, FU = √(1 -2)² + (9- 2)² = √1 + 49 = √50 = 5√2

OR = √(5+2)² + (6-5)² = √49 +1 = 5√2

So, the given figure is square because the length of Diagonal are equal.

Transformation to be done → [tex]R_{180}0T_{-3,-4}[/tex]

Transformations to be done,

Step - (1). Translation of the given by 3 units left and 4 units down.

Step - (2). Followed by the rotation counterclockwise 180° about the origin.

Rule for step (1),

(x, y) → (x - 3, y - 4)

By this rule,

Awnser:

1/2 as m, and -3 as b

Step-by-step explanation:

To find the equation of any line, you use the formula: mx+b=y, where m is the slope, y is the y coordinate, b is the y intercept, and x is the x coordinate.  However, it only asks for b and m.

You'll need to first find 2 points.

I chose: (6,0) and (0,-3).

The formula to find the slope is: y2-y1/x2-x1.

0-(-3)/6-0

0+3/6

3/6

1/2

Now we need to find the y intercept. However, the graph already tells you what it is. The y intercept always has to have 0 as x.

So the awnser is 1/2 as m, and -3 as b.

Answer:

Step-by-step explanation:

Compounded quarterly, the amount in the account will be ...

  A = 6500(1 +.0325/4)^(4·5) ≈ 7641.89

Compounded continuously, the amount in the account will be ...

  A = 6500e^(.0325·5) = 7646.91

So, the account compounding continuously has the higher yield, by the amount of ...

  $7646.91 -7641.89 = $5.02

Heres a set of data 2.4, 1.6, 3.2, 0.3, 1.5 each peice of data is increases by 10, what is the mean? each new peice of data is doubles, whats the new mean?

Answers

Step-by-step explanation:

Mean is the ratio of the sum of the sample data to the total sample size.

1) Given the set of data 2.4, 1.6, 3.2, 0.3, 1.5, if each piece of data is increases by 10, the new data's will be;

(10+2.4), (10+1.6), (10+3.2), (10+0.3), (10+1.5)

sum of the new data's = 59

Sample size = 5

Mean = 59/5

Mean = 11.8

Hence if the price of data is increases by 10, its new mean will be 11.8

2) If each new piece of data is doubles, the new set of data will be;

2(2.4), 2(1.6), 2(3.2), 2(0.3), 2(1.5)

= 4.8, 3.2, 6.4, 0.6, 3.0

Sum of new data = 4.8+3.2+6.4+0.6+3.0

Sum of new data = 18

sample size = 5

Mean = 18/5

Mean = 3.6

Hence the new mean if the data were doubles is 3.6
