Lamar ate 35% of the candies in the bag. If Lamar ate 28 candies, how many candies were there total in the bag?

Answer:

8820 ways

Step-by-step explanation:

Given that :

Selecting 4 pairs of pant from 8 available and selecting 5 shirts from 9 available

Using combination :

4 pants from 8 = 8C4

5 shirts from 9 = 9C5

Recall:

nCr = n! / (n-r)! r!

8C4 * 9C5 = [8! /(8-4)!4!] * [9! /(9-5)!5!]

8C4 * 9C5 = (8! /4!4!) * (9! /4!5!)

8C4 * 9C5 = 70 * 126

8C4 * 9C5 = 8820 ways

Answer:

A liter of milk cost $0.75 and a loaf of bread cost $1.75

Step-by-step explanation:

Let the liters of milk by represented by m

Let the loaves of bread by represented by b

Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11

3m + 5b = 11...... Equation 1

A month later, he bought 4 liters of milk and 4 loaves of bread at the same prices, for a total of $10

4m + 4b = 10.... Equation 2

Combining the Equations

3m + 5b = 11...... Equation 1

4m + 4b = 10.... Equation 2

We solve using the Elimination method

Multiply Equation 1 by 4 and Equation 2 by 3 to eliminate m

12m + 20b = 44..... Equation 3

12m + 12b = 30....... Equation 4

Substract Equation 4 from Equation 3

8b = 14

b = 14/8

b = $1.75

Solving for m

3m + 5b = 11...... Equation 1

3m + 5($1.75) = 11

3m + $8.75 = $11

3m = $11 -$ 8.75

3m =$ 2.25

m =$ 2.25/3

m = $0.75

Therefore,

a liter of milk cost $0.75 and a loaf of bread cost $1.75

Answer:

-5x > 10

Step-by-step explanation:

1. We know that when -14 thrown to the right hand side, it will turn to +14

2. +14 -4 = +10

3. Left hand side will remain -5x

4. Hence, -5x > 10

5. and the equation divided by -5, the > sign will change to <

6. x< -2

7. Since you're finding the missing step so it's -5x > 10

Answer:

BCE= 115    ECD=65

Step-by-step explanation:

(5x+10)+(3x+2)=180

8x+12=180

8x=168

x=21

5(21)+10=115

3(21)+2=65

Answer:

<BCE=115°

<ECD=65°

And their sum is 180°

Step-by-step explanation:

< BCE + <ECD =180° ( Being sum of supplementary angle which is formed in the given diagram is 180°)

(5x + 10)° + (3x + 2)°= 180°

5x + 10 + 3x + 2 = 180°

5x + 3x + 10 +2 = 180°

8x + 12= 180°

8x = 180°-12°

8x = 168

x= 168/8

x=21°

Now,

<BCE = 5x+10

= 5*21+10

=105+10

=115

<ECD

= 3x+2

= 3*21+2

Answer:

48.5 km/h

Step-by-step explanation:

speed = distance/time

distance =56km

time = 1814h - 1722h

time = 52 min = 52/60h =13/15h

speed = 56*13/15

speed = 48.53

into 1dp= 48.5 km/h

Answer =

So first remember the formula:

Distance/Time= Speed.

Now you see how many minutes it is from 17:22 to 18:14.

17:22 > 18.14 = 52 minutes, 1 Hour = 60 minutes. Hence, 52/60.

Then you get your calculator and do, 56 km/ 52/60

So what I mean is basically 56 km *fraction line* 52 *another fraction line* and then 60 in your calculator. Then you will get a fraction then press SD in your calculator.

You should get 64.6153....

Now the final step is to round it to the 1st decimal place, so

64.6|153 after 64.6 is the first decimal place which is (1) and 1 is below 5 so it will not go up and therefore stay the same so, your Answer is: 64.6 km/h.

Hope it helped!

Answer:

y = 2 for x < 0

     x for 0 ≤ x < 3

     3 for x ≥ 3

Step-by-step explanation:

From the graph attached,

Equation of line (1),

y = 2

Where x < 0

Let the equation of line (2) is,

y = mx + b

y-intercept 'b' = 0 [line (2) passes through origin]

Slope of the line 'm' = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

                                 = [tex]\frac{3}{3}[/tex]

                                 = 1

Therefore, equation of line (2) will be,

y = x

where 0 ≤ x < 3

Equation of line (3) will be,

y = 3

Where x ≥ 3

Therefore, piecewise linear function will be,

y = 2 for x < 0

     x for 0 ≤ x < 3

     3 for x ≥ 3

Answer: Third option.

Step-by-step explanation:

We have the variables:

x =  number of roses that Sarah buys

y = number of carnations that Sarah buys.

Each rose costs $3, then the price for x roses is: x*$3.

Each carnation costs $1, then the price for y carnations is: y*$1.

The total price will be:

$3*x + $1*y

And she can spend no more than $75, then we have the inequality:

$3*x + $1*y ≤ $75

Writing this as a line, we have:

y ≤ 75 - 3*x

Then the graph of this will be:

A solid line with a negative slope and the shaded part will be below that line.

The value of y goes between 0 and 75.

The value x goes between 0 and the value of x such y = 0, this is:

y = 0 ≤ 75 - 3*x

 3*x ≤ 75

     x ≤ 75/3 = 25

Then the value of x goes between 0 and 25.

The correct option will be the third one.

The correct graph is option 3.

Given,

Sarah buys x no. of roses and y no. of carnations.

The cost of each roses be $3, so cost of x roses be 3 x .

And the cost of each carnations be $1, so cost of y carnations be y.

The total cost will be  [tex]3x + y.[/tex]

But as given in question she can spend no more than $75, so we have the inequality  [tex]3x + y \leq 75[/tex].

Writing the above equation as a line we have  [tex]y\leq 75-3x[/tex].

So graph of above line will be a solid line with a negative slope and the shaded part will be below that line so the value of y goes in between 0 and 75.

Now, value of x when y is o will be calculated from  [tex]y\leq 75-3x[/tex].

[tex]0\leq 75-3x[/tex]

[tex]3x\leq 75[/tex]

[tex]x\leq \frac{75}{3}[/tex]

[tex]x\leq 25[/tex]

Now we have values of x in between 0 and 25.

here we have y in between 0 and 75 with a negative slope and x in between 0 and 25. so the shaded part will be below that line goes in between 0 and 75 on y axis . option 3 has shaded part in between 0 and 75 on y axis  so the correct option is 3.

The smaller number is 14 and the larger number is 36.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let the smaller number would be x

And the larger number would be y

Given that the smaller of two numbers is 2 less than 1/3 the larger

So x - 2 = (1/3)y ⇒ 3x - 6 = y

The sum of the two numbers is 50

So x + y = 50

Substitute the value of equation 3x - 6 = y in the above equation,

⇒ x + 3x - 6 = 50

⇒ 4x = 50 + 6

⇒ x = 56/4

⇒ x = 14

Substitute the value of equation x = 14 in the equation x + y = 50,

⇒ 14 + y = 50

⇒ y = 36

Hence, the smaller number is 14 and the larger number is 36.

The quotient to describe the rate of change in the squirrel’s height above the ground is 27.619 feet per seconds to the nearest hundredth.

Given data

height below ground = 45 feet

height above the ground = 100 feet

time of travel = 5.25 seconds

Rate of change calculation

total distance moved by the squirrel = height below ground + height above the ground

= 45 feet + 100 feet

= 145 feet

rate of change = total distance / time of travel

= 145 feet / 5.25 seconds

b) The new ordered pairs are X' (6, 9), Y' (7, 12), Z' (4, 4)

Step-by-step explanation:

∵ X = (-3, 7), Y = (-2, 10), and Z = (-5, 2)

∵ The points reflected in the x-axis

→ Change the signs of the y-coordinates of the 3 points

a) The new ordered pairs are X' (-3, -7), Y' (-2, -10), Z' (-5, -2)

∵ X = (-3, 7), Y = (-2, 10), and Z = (-5, 2)

∵ The points translated to be (x + 9, y + 2)

→ That means add the x-coordinates by 9 and y-coordinates by2
