Answer 1a 18 1b 36 1c 648

1a : if you look at the shape you will see its made of squares. I counted the squares, its 18.

1b : one side is 6 in. since its a square all sides are equal. so multiply 6 by 6 to get 36.

1c : this one is easy. We take the number of squares across the surface (18) by the area of each square (36) it is 648.

Also sorry I didn't make this clearer earlier.

Answer:

14 hours

Step-by-step explanation:

Let x be the number of hours open on each of the four days (because it is six days per week) that are not Saturday or Sunday. Thus, the total number of hours on those days would be 4x. Then, we are told that Sam's Soups are open 2 hours longer on Saturdays and Sundays, so that would be x + 2. There are two of those days, so that would be 2(x + 2). Since all of these hours total 76, we have our equation:

4x + 2(x + 2) = 76

4x + 2x + 4 = 76

6x = 72

x = 12

Remember, 12 hours is the number of hours that Sam's Soups is open on days that are not Saturday and Sunday. Those days are x + 2. Thus, that is 12 + 2 = 14 hours.

Answer:

14 hours

Step-by-step explanation:

x = hours on day other than saturday and sunday

y = hours on Saturday and Sunday.

Sam's soups are only open 6 days a week, and 2 are weekends, so it is only open on 4 weekdays.

4x + 2y = 76

We know the hours on Saturday and Sunday are 2 hours more than the weekday hours.

So,

y = x + 2

Substituting that back into the original equation,

4x + 2(x+2) = 76

4x + 2x + 4 = 76

6x = 72

x = 12

y = 14

So Sam's Soups is open 14 hours on Sunday.

Answer:

draw a line that makes a triangle and rectangle.

hypotenuse= 30

3k-4k-5k triangle

18-24-30

so the short part of triangle is 18 cm

sorry for language I am not familiar with English

the perimeter of this shape is

24+10+10+30+\(\sqrt{30^{2} -24^{2} }\) = 92 cm

Answer:

$260.93

Step-by-step explanation:

$245 x 6.5% = $15.925 Tax

$15.925 rounds to $15.93

$245 + $15.93 = $260.93

Answer:

There are two ways to check if 3x+5=11 is true:

Subtract 5 from both sides of the equation. This will isolate x on the left-hand side of the equation.

3x = 6

Divide both sides of the equation by 3. This will divide both sides of the equation by 3, which will cancel out the 3 on the left-hand side of the equation, leaving x by itself.

x = 2

You can also check if 3x+5=11 is true by plugging in 2 for x. If you do this, you will get 3(2)+5 = 6+5 = 11. Therefore, 3x+5=11 is true when x=2.

Answer:

mode

Step-by-step explanation:

the mode is 60-69

it has the most frequency

Answer:

  (c) number of data points

  (d) mode interval

Step-by-step explanation:

You want to know which descriptive statistics can be determined from the given histogram.

The median is the middle data value. Here, the numbers of data points in each interval are 6, 9, 8, 6, 4, for a total of 33 data points. The middle one is point 17, which is found in the interval 70–79. We cannot determine the median value any closer than that.

The median cannot be determined from the histogram.

The mode is the value that occurs most often. Since data is grouped, we have no idea what value may occur most often. We can say the interval with the most data points is 60–69, which means we can determine the mode interval, but not the mode.

The mode cannot be determined from the histogram.

As we have noted above, the number of data points is 33.

The number of data points can be determined from the histogram, choice C.

As we have noted above, the interval with the most data points is 60–69. The mode interval can be determined from the histogram, choice D.

Answer:

$7.95

Step-by-step explanation:

The equation c = 7.95b represents the total cost of the boxed lunches

c represents the total cost

b represents the number of boxed lunches

To find the total cost of multiple items, you generally multiply the cost of a single item by the number of items there are.

Using this, we can find the cost per item is 7.95 dollars, or 7 dollars and 95 cents.

Answer:

104in2

Step-by-step explanation:

The area, in square inches, of the painted face of the brick is Option C 104 \(in^{2}\).

Using the Quadrant system of the Number line

B (-4,2) lies in the 2nd quadrant.

C (-4,-11) lies in the 3rd quadrant

A (4,2) lies in the 1st quadrant

D (4,-11) lies in the 4th quadrant

Length of Side AB= Length of Side CD= Distance between x coordinate of A & B OR Between C & D i.e. 8 in

Length of Side BC= Length of side  AD= Distance between y coordinate of A & D OR Between B & C i.e. 13 in

Area of the Square ABCD= (length of Side AB or CD) X (Length of Side  BC or AD)

                                          = (8 x 13) \(in^{2}\)

                                          = 104 \(in^{2}\)

Thus, Area of square is 104 \(in^{2}\).

Answer:

[ 2] − | −5 + 7 |

Step-by-step explanation:

Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.

Step 1) Solve. | −5 + 7 | = 2.

Step 2) Find which other absolute value is equal to -2.

After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.

We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0
