Answer:
15x + 20
Step-by-step explanation:
Answer:
66
Step-by-step explanation:
Find the area of the rectangle, then add up the area of the triangle.
The area of the rectangle
= 5 × 12
= 60 cm²
The <u>base</u> of the triangle
= 12 - 9
= 3 cm
The <u>height</u> of the triangle
= 9 - 5
= 4 cm
The area of the triangle
= (3 × 4) ÷ 2
= 6 cm²
The total area of the figure
= 60 + 6
= <u>66 cm²</u>
Answer:
The ratio level of measurement is most appropriate because the data can be ordered differences can be found and are meaningful, and there is a natural starting zero point.
That's the correct answer since our variable is numerical and have a natural starting point at 0 and the negative values not makes sense.
Step-by-step explanation:
The interval level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is no natural starting point.
Our variable is numerical but we have a starting point defined so it can't be an interval variable.
The nominal level of measurement is most appropriate because the data cannot be ordered.
False on this case the bolume can't be a nominal variable since we don't have a categorical variable.
The ordinal level of measurement is most appropriate because the data can be ordered, but differences (obtained by subtraction) cannot be found or are meaningless.
False we don't have ordered relationship among the variable’s observations
The ratio level of measurement is most appropriate because the data can be ordered differences can be found and are meaningful, and there is a natural starting zero point.
That's the correct answer since our variable is numerical and have a natural starting point at 0 and the negative values not makes sense.
we have to find address of element -5 in the matrix
We know that
horizontal line represents number of rows
vertical line represents number of columns
We can see that
-5 is in third row
and -5 is in second column
Suppose, we have element in matrix
Here , m is number of rows
and n is number of columns
so, we got
now, we can plug these values
and we get

Answer:
15 dozens of cakes
Step-by-step explanation:
It is given that Jeanna is making cupcakes for her family and she normally makes 2 dozens of red velvet cakes and 3 dozens of gingerbread spice cakes. But as everybody is staying at home, Jeanna wants to increase the standard amount by 3 for enough cakes.
So,
2 dozens of velvet cakes, i.e.
2 x 12 = 24 red velvet cakes
Increasing this amount by 3 times will give us 24 x 3 = 72 red velvet cakes.
Similarly,
3 dozens of gingerbread spice cakes, i.e.
3 x 12 = 36 gingerbread spice cakes
Increasing this amount by 3 times will give us 36 x 3 = 108 gingerbread spice cakes.
Therefore the total number of cakes is = 72 + 108
= 180 cakes.
We know 1 dozen = 12
Therefore dividing 180 cakes by 12, we get
= 15 dozen cakes.
Therefore, now Jeanna will have to make 15 dozens of cupcakes for all.
