Answer:

6.6 stone

Step-by-step explanation:

We will use conversions to change kilograms to stones

1 kilogram= 2.2 pounds,

1 stone= 14 pounds

42 kilogram          2.2 lbs           1 stone

---------------       * -------------   * ---------------

                           1 kg                 14 lbs

All the units cancel except stone

(42*2.2)/14  stone

6.6 stone

Answer:

42 kilograms is equal to 6.6 stones.

Step-by-step explanation:

Given :

1 kilogram = 2.2 pounds

1 stone = 14 pounds

42 kilograms into stones  =  ? stones

Solution:

42 kilograms = [tex]42\times 2.2 pounds=92.4 pounds[/tex]

And , 1 stone = 14 pounds

[tex]1 pound = \frac{1}{14} stones[/tex]

[tex]92.4 pounds=92.4\times \frac{1}{14} stones=6.6 stones[/tex]

So, 42 kilograms is equal to 6.6 stones.

Answer:

expression for total cost is given by

[tex]0.80(3.95x+4.25y+5.99z)[/tex]

Step-by-step explanation:

Here we need to find the expression for the total cost

Let us find the cost for x pounds of peanut , y pounds of cashews and z pounds of almonds

cost of 1 pound of peanut = $3.95

cost of x pounds of peanut = $3.95x

cost of 1 pound of cashews = $4.25

cost of y pounds of cashews = $4.25y

cost of 1 pounds of almonds = $5.99

cost of z pounds of almonds = $5.99z

total cost = [tex]3.95x+4.25y+5.99z[/tex]

cost after 20% off = total cost - 20% of total cost

                                         = 80% of total cost  

cost after 20% off =80%[tex](3.95x+4.25y+5.99z)[/tex]

cost after 20% off =[tex]0.80(3.95x+4.25y+5.99z)[/tex]

now we can plug x= 2 , y= 3 and z=1

so we have

cost after 20% off =[tex]0.80(3.95(2)+4.25(3)+5.99(1))[/tex]  =$ 21.31          

The expression is ((2 x $3.95) + (3 x $4.25) + (1 x $5.99)) x (1 - 0.20) which equals to $21.31.

To find the total cost of 2 pounds of peanuts, 3 pounds of cashews, and 1 pound of almonds with a 20% discount, we need to first calculate the original total cost of the nuts without the discount.

We do this by multiplying each type of nut's price per pound by the number of pounds purchased and summing these amounts up.

The cost for the peanuts is 2 pounds x $3.95 per pound = $7.90.

For the cashews, it is 3 pounds x $4.25 per pound = $12.75.

For the almonds, it is 1 pound x $5.99 per pound = $5.99.

The sum of these costs will give us the total original cost.

The total original cost is therefore $7.90 (peanuts) + $12.75 (cashews) + $5.99 (almonds) = $26.64.

Next, we apply the 20% discount by multiplying the total original cost by 20% (or 0.20) to find the discount amount, and then subtract this discount amount from the total original cost to find the discounted total cost:

Discount amount = $26.64  imes 0.20 = $5.33. Discounted total cost = $26.64 - $5.33 = $21.31.

Therefore, the expression that can be used to find the total cost is: ((2 x $3.95) + (3 x $4.25) + (1 x $5.99)) x (1 - 0.20)

The coefficients and constants of the equations are proportional to each other because the graphs of the two equations overlap each other.

The correct option is C.

When Henry multiplied the first equation by -3 and added the two equations together, resulting in the equation 0 = 0, it indicated that the two original equations were dependent and represented the same line. This means that the system of equations has infinitely many solutions. Each point on the line represented by the equations satisfies both equations simultaneously.

When Henry graphed the equations on his graphing calculator and saw only one line, it further confirmed that the two equations are identical or overlapping. The lack of a visible second line indicates that the graphs coincide with each other, overlapping perfectly. This occurs because the coefficients and constants of the equations are proportional to each other, resulting in the same line when graphed.

Hence, option C is the correct choice, as the overlapping of the graphs confirms that the system of equations has infinitely many solutions.

Answer:

Last choice

Step-by-step explanation:

Let's assume m is the "y" (dependent variable) and d is the "x" (independent variable) because the number of minutes is larger, and that would make more sense.

5760/4=1440

10080/7=1440

...

Slope is 1440, and it is direct variation

m=1440d

It COULD also be the third choice, but mathematical convention would have us put the coefficient first.

Answer:

[tex]\frac{170}{100}m[/tex]

[tex]1.7m[/tex]

Step-by-step explanation:

Here,

Before the outbreak, the average wait time at the hospital was m minutes,

Also, after outbreak it is increased by 70 %,

So, the average wait time at the hospital after the outbreak = The average wait time before outbreak + 70 % of the average wait time before outbreak

= m + 70 % of m

[tex]=m+\frac{70m}{100}[/tex]

[tex]=\frac{100m+70m}{100}[/tex]

[tex]=\frac{170m}{100}[/tex]

[tex]=1.7m[/tex]

Hence, the expressions could represent the average time at the hospital after the outbreak would be,

[tex]\frac{170}{100}m[/tex]

[tex]1.7m[/tex]

The actual measurements are 12 feet by 24 feet.

The ratio between a distance on a map and its corresponding distance on the ground is referred to as the "map scale."

The scale of a map is the proportion between the distance shown on paper and the actual distance on the ground.

Given:

1 inch = 16 feet.

Dimension of bedroom on blue print is 0.75 inches x 1.5 inches.

so, the actual dimension of bedroom is

= 0.75 x 16 by 1.5 x 16

2√5 + 9√7

Step-by-step explanation:

The given expression is

2√20 - 3√7 - 2√5 + 4√63

√20 = √4√5 = 2√5

√63 = √9√7= 3 √7

Now replace the above value with the given expression

2*2√5 - 3√7 -2√5+4*3√7

= 4√5 - 3√7-2√5+12√7

= 4√5 -2√5 - 3√7 +12√7

Thank you.

The expression 2 sqrt(20) - 3 sqrt(7) - 2 sqrt(5) + 4 sqrt(63) simplifies to 2 sqrt(5) + 9 sqrt(7) after breaking down and combining like radicals.

We start by simplifying each radical. Notice that sqrt(20) can be written as sqrt(4*5), which simplifies to 2sqrt(5). Similarly, sqrt(63) can be written as sqrt(9*7), which simplifies to 3sqrt(7). Therefore, our expression becomes:
2(2sqrt(5)) - 3sqrt(7) - 2sqrt(5) + 4(3sqrt(7)) = 4sqrt(5) - 2sqrt(5) - 3sqrt(7) + 12sqrt(7) = 2sqrt(5) + 9sqrt(7). This gives us the simplified form of the original expression.

Answer:

Step-by-step explanation:

If the lines are parallel, then angles 1, 7, 3, and 5 are congruent because they are vertical/corresponding angles.

Therefore, they are all 113 degrees. For the rest of them, you just subtract from 180 to get 67. Therefore,

2 = 67 degrees

3 = 113 degrees

4 = 67 degrees

5 = 113 degrees

6 = 67 degrees

7 = 113 degrees

8 = 67 degrees

Answer:

16%

Step-by-step explanation:

The mean is $15 and the standar deviation is $3.

mean = 15  and SD = 3

We need to find percentage less than 12 per hour

P(x<12)= P(x=12)

to find P(x=12) we find z-score

[tex]z= \frac{x-mean}{SD} =\frac{12-15}{3} =-1[/tex]

Now use z-score table . z-score = 0.1587

P(x=12)=0.1587

To get percentage we multiply by 100

0.1587 * 100 = 15.87 = 16%

Step-by-step explanation:

The two triangles are similar .

We can use the ratio's of the side to figure out x

2                3.5

-------- = --------------

4               x

Using cross products

2x = 4*3.5

2x=14

Divide each side by 2.

2x/2 = 14/2

x=7

the length of x = 7.

To solve for x using the given ratios of the sides of the two similar triangles, we can follow these steps:

Set up the proportion using the given ratios:

[tex]\[ \frac{2}{4} = \frac{3.5}{x} \][/tex]

Cross multiply:

[tex]\[ 2x = 4 \times 3.5 \][/tex]

Perform the multiplication on the right side:

2x = 14

To solve for x, divide both sides of the equation by 2:

[tex]\[ \frac{2x}{2} = \frac{14}{2} \][/tex]

Simplify both sides:

[tex]\[ x = \frac{14}{2} \][/tex]

Calculate the value:

x = 7

So, x = 7.

C. 2 1/8 ounces

Step-by-step explanation:

The kitten gained 2 1/8 ounces, and you can prove it through the following reasoning.

Kitten at birth was 3 3/8 ounces

Gained Weight (WG) was (unknown)

The kitten was 5 1/2 after being sold.

5 1/2 - 3 3/8 = GW (please note that 1/2 is also 4/8, therefore the equation can be represented by 5 4/8 - 3 3/8 = GW

2 1/8 = GW

Answer: The kitten gained 2 1/8 ounces

Step-by-step explanation:

We have to find the difference between the weights of kitten.

5 1/2 - 3 3/8 = weight gained

We solve the compound fraction like this.

5 1/2

2*5+1 = 11

This goes to 11/2

While

3 3/8

8*3+3 = 27

This goes to 27/8

So we subtract 11/2 - 27/8

44 - 27/8

17 / 8

This comes to 2 1/8 ounces.
