A tortoise is walking in the desert. It takes
4
minutes to walk
6.4
meters. What is its speed?

Answers

speed = distance / time

Here, speed = 6.4 meters  /  4 minutes  =1.6 meter / minute (answer)
The formula for speed is S = Distance/Time.
if you plug 6.4 in for distance and 4 in for time, s = 6.4/4. 6.4/4 = 1.6, so the speed of the tortoise is 1.6 meters per second, or 1.6 m/s

6 times the sum of a number t and 5 is s

Answers

Final answer:

The verbal statement '6 times the sum of a number t and 5 is s' is translated into the algebraic equation 6(t + 5) = s, which is a linear equation used to solve for either t or s.

Explanation:

The student's question involves creating an algebraic equation from a verbal statement. In this case, the expression '6 times the sum of a number t and 5 is s' can be translated into an algebraic equation. To do so, we first represent the sum of the number t and 5 as (t + 5). We then multiply this sum by 6 to represent '6 times the sum', which gives us the equation 6(t + 5) = s.

This equation allows us to solve for the number t when s is known, or vice versa. It is a basic linear equation that can be used in various mathematical problems to determine the value of s given a specific t, or to find t when s is known.

Mr. Jansen is building an ice rink in his backyard that will measure 8.4 meters by 22 meters. What is the area of the rink?

Answers

The area of Mr.Jansen ice rink in the backyard is 184.8

The area of the rink is 184.8 m²

Further Explanation

From the problem above we know the measurement of the ice rink is

22 x 8.4 m

to calculate the area = length x width

                                   = 22 x 8.4

Here is how to solve the decimal multiplication, we are going to multiply them as a whole number. The different is the placement of the decimal point in the answer. Using the standard algorithm method, the calculation would be:

 22             ⇒ whole number (no decimal place)

 8.4  x        ⇒ 1 decimal place

 88          

176  +

184.8           ⇒ 1 decimal place

The first factor 22 doesn't decimal place

The second factor 8.4 has one decimal place

The result will has one decimal place (0+1=1)

find the value of x. the diagram is not to scale.

Answers

opposite angles are equal so where the 110 is outside the triangle, it is also 110 inside the triangle.

 the 3 angles need to = 180

 so you have 110 + 57 = 167

x = 180-167 = 13

x = 13

The top angle is going to be 110 too so you add 110 and 57 which equals 167. Subtract that from 180 and the answer is x=13

To evaluate the expression (3-1)³ + 7(6) - 5/2, simplify the components individually and then substitute the values back into the expression to find the final result of 47.5.

Evaluate the expression:

First, we simplify the expression:

Substitute these values back into the expression: 8 + 42 - 2.5 = 47.5

26,000 rounded to NEAREST ten thousand

Answers

30,000, because if you look in the 6 in the thousands place it is over 5 so you round up

The value after rounding 26,000 to its nearest ten thousands is 30,000.

Given,

26,000

We need to round to its nearest ten thousands.

What is the place value of a number?

Example:

235678

8 - ones

7 - tens

6 - hundreds

5 - thousands

3 - ten thousands

2 - hundred thousands

Round 26,000 to its nearest ten thousand.

26,000

2 is in ten thousands place value.

So we need to round either to 20,000 or 30,000.

Since 26000 > 2499 we will round to 30,000.

= 30,000

Thus 30,000 is our answer.

Answer:

[tex]y=2x+2[/tex]

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

we have

[tex]A(-4,-6)\ B(2,6)[/tex]

Substitute the values

[tex]m=\frac{6+6}{2+4}[/tex]

[tex]m=\frac{12}{6}=2[/tex]

step 2

we know that

The equation of the line into slope intercept form is equal to

[tex]y=mx+b[/tex]

we have

[tex]m=2[/tex]

[tex]B(2,6)[/tex]

substitute and solve for b

[tex]y=mx+b[/tex] ------> [tex]6=(2*2)+b[/tex]

[tex]6=4+b[/tex]

an auto transport truck holds 12 cars. A car dealer plans to bring in 1006 new cars in June and July. if an auto transport truck is filled for each delivery, except for the last one, how many full truckloads are needed and how many cars will be in the last truck?

Answers

divide 1006 by 12

1006 / 12 = 83.833

so 83 full trucks

83 *12 = 996

1006-996 = 10 cars will be on the last truck

Final answer:

To transport 1006 cars, 84 full truckloads are needed, with 10 cars in the last truck.

Explanation:

To calculate the number of full truckloads needed, we divide the total number of cars (1006) by the number of cars a truck can hold (12).
1006 / 12 = 83.83...

Since we can't have a fraction of a truckload, we round up to the nearest whole number.
Therefore, we need 84 full truckloads.

To find the number of cars in the last truck, we subtract the number of cars in the full truckloads from the total number of cars.
1006 - (83 * 12) = 1006 - 996 = 10

So, the last truck will have 10 cars.
