Answer: 3

Answer:

To answer the problem above we let x be the number of people who prefers salad and y be the number of people who chose steak. For lunch they will be spending $41. That is,

                                  7x + 10y = 41

Now, for dinner they will be spending $51. That is,

                                9x + 12y = 51

The values of x and y from both equations are 3 and 2, respectively. Therefore, 3 people will choose a salad

Answer:

3 pounds

Step-by-step explanation:

1. 50 + 50 = 100

2. 100 / 5 = 20

3. 60 / 20 = 3

Each chicken eats approximately 0.3333 pounds of feed per day, which is calculated by dividing the total feed (100 lbs) by the number of days (60) and then by the number of chickens (5).

To calculate how much chicken feed each chicken eats a day, we need to start by understanding the total amount of feed Ryan bought. He bought two 50 lbs bags, which is a total of 100 lbs of chicken feed. Since the feed needs to last 60 days for 5 chickens, we will divide the total feed by the number of days and then by the number of chickens.

First, we convert the weight of the feed into pounds (if it is not already in pounds). We know there are 100 lbs of feed in total.

Next, we divide the total weight of the feed by the number of days to find out how much feed is used per day:
100 lbs / 60 days = 1.6667 lbs per day (for all 5 chickens together).

Finally, we divide the daily feed consumption by the number of chickens to find out how much each chicken eats per day:
1.6667 lbs per day / 5 chickens = 0.3333 lbs per chicken per day.

Therefore, each chicken eats approximately 0.3333 pounds of feed a day.

Answer: Both £56

Step-by-step explanation:

We deliver: 10 x 20 x 40 = 8000

8000 x 0.80/cm = £56

£56

Go Parcels: 2(10 x 20) + 2(10 x 40) + 2(20 x 40) = 2800

Hello! Remember you have to write complete questions in order to get good and exact answers. Here you haven't provided any diagram, so I'll assume ΔSTU and ΔDEF are similar. Two triangles are similar if and only if their corresponding angles are congruent and their corresponding sides are in proportion.

So:

[tex]\angle S=\angle D \ldots eq1 \\ \\ \angle T=\angle E \ldots eq2 \\ \\ \angle U=\angle F \ldots eq3[/tex]

We also know:

[tex]\angle S+\angle T+\angle U=180^{\circ} \ldots eq4 \\ \\ \angle D+\angle E+\angle F=180^{\circ} \ldots eq5[/tex]

Suppose we know:

[tex]\angle S=30^{\circ} \\ \\ \angle E=110^{\circ}[/tex]

Then, by eq2:

[tex]\angle T=\angle E =110^{\circ}[/tex]

By substituting ∠S and ∠T into eq4:

[tex]\angle S+\angle T+\angle U=180^{\circ} \\ \\ 30^{\circ}+110^{\circ}+\angle U=180^{\circ} \\ \\ \\ Isolating \ \angle U: \\ \\ \angle U=180^{\circ}-(30^{\circ}+110^{\circ}) \\ \\ \angle U=180^{\circ}-140^{\circ} \\ \\ \angle U=40^{\circ}[/tex]

Finally:

Answer:

D

Step-by-step explanation:

The length of the paintbrush in centimeters is D. 10.1 cm.

Unit conversion is defined as expressing the same quantity by different measurement units.

For example, a distance of 20 meter can be also expressed as 2000 cm. The distance is same.

Given that,

Length of the paintbrush in millimeters = 101 millimeters

We have to find the length of the same paintbrush in centimeters.

We have the unit conversion,

1 centimeter = 10 millimeters

So,

1 millimeter = 1/10 = 0.1 centimeters

So, we have to multiply the measurement in millimeter with 0.1.

101 millimeters = 101 × 0.1 = 10.1 centimeters

Hence the length is 10.1 centimeters

Any obtuse triangle will also have two acute angles.

__

The sum of angles in a triangle is 180°. If one of the angles is 90° or more (a right or obtuse angle), the other two (non-zero) angles must be less than 90°.

An obtuse triangle is one that has an obtuse angle, so both of the remaining angles must be less than 90°, that is, they must be acute angles.

Yes

The y deduct the daily fee

deduct means subtract which means the daily fee is 55

d is the number of deliveries in one day

delivery company pays its drivers a fixed fee for each delivery made

Since d is the number of delivers, 11 must be the fee for each delivery made

Answer:

fee paid per delivery

Step-by-step explanation:

The constant of variation k for the inverse variation is found to be 8. When x = 32 is substituted into the formula y * x = k, we find that y = 0.25.

In problems where y varies inversely with x, it means that their product is constant. This can be represented as y * x = k, where k is the constant of variation. Given that y = 16 when x = 0.5, we can find the constant by plugging these values into the formula. Hence, 16 * 0.5 = k, so k = 8.

Now to find y when x = 32, we substitute these values into the formula. We know that y * 32 = 8, so y = 8 / 32. This simplifies to y = 0.25.

Answer:

x+20

Step-by-step explanation:

As we can see n the diagram, there are parallel traversals and one line, and the two angles given are same-side interior angles. We know that when there is parallel traversal, and we have same side interiors, the sum of the measure of the two angles are supplementary. Supplementary means 180 degrees, or a straight line.

So we plug everything in and we have  4x+5x=180 degrees

4x+5x=9x, so 9x=180

We divide by 9 on both sides to get the value of x, which is 20

Cost of your guitar = $ 600

Let your friend's guitar's cost be = n

According to the question =

Your guitar costs $ 40 more than twice the cost of your friend's guitar which is n ,but your guitar's cost is $ 600.

So ,the linear equation for this will be =

= 2n+$40 = $600

= 2n = $600-$40

= 2n = $ 560

= n = $ 560/2

= n = $ 280

The cost of your friend's guitar is $280 by creating an equation based on the cost comparison to your own guitar, and then solving for the variable representing your friend's guitar's cost.

You paid $600 for a new guitar, which costs $40 more than twice the cost of your friend's guitar. To find the cost of your friend's guitar, let's denote the cost of your friend's guitar as x. According to the information given, your guitar's cost can be represented by the equation 2x + $40 = $600. Solving for x will give us the following steps:

Subtract $40 from both sides of the equation: 2x = $600 - $40.

This simplifies to 2x = $560.

Divide both sides by 2: x = $560 / 2.

Therefore, x equals $280.

The cost of your friend's guitar is $280.

The probability of drawing at least one red marble from a bag containing 3 blue and 5 red marbles in two draws without replacement is 19/28.

To find the probability of drawing at least one red marble from a bag with 3 blue and 5 red marbles, with one draw already taken, we calculate the probability of not drawing a red marble and subtract that from 1. Since there are more red than blue marbles, the probability of drawing a red one on the first draw is higher. However, the problem states that the marbles are not replaced after drawing, so the probabilities change with every draw.

There are two ways to not draw a red marble in two draws:

First draw: blue, Second draw: blue.

First draw: red, Second draw: blue.

Let's calculate these probabilities. For the first case, there's a 3/8 chance of drawing blue first, and then 2/7 chance of drawing blue again, since one blue marble has been removed, which equals to 3/8 * 2/7 = 6/56 or 3/28. For the second case, there is a 5/8 chance of drawing red first, and then a 3/7 chance of drawing blue, equalling 5/8 * 3/7 = 15/56. The sum of these probabilities is 3/28 + 15/56 = 9/28.

Therefore, to find the probability of at least one red, we subtract the summed probabilities from 1: 1 - 9/28 = 19/28.

Thus, the probability of drawing at least one red marble is 19/28.
