Allushta [10]

Answer:

2 years

Step-by-step explanation:

13000 X 0.05 = 650

13000 - 650 = 12350 year 1

12350 X 0.05 =617.5

12350 - 617.5 =11732.5 year 2

If there are 7 bolts in a widget and 6 widgets in an appliance, how many bolts are in 20 appliances?

sweet [91]

A single appliance has 6 widgets, and a widget has 7 bolts. Therefore, you need to multiply 6 by 7 to find the number of bolts in a single appliance.

6 x 7 = 42

Now that you know the number of bolts in an appliance, you can find the number of bolts in 20 appliances by multiplying 42 by 20.

42 x 20 = 840

Hence, there are 840 bolts in 20 appliances.

Select all the statements that are true

masya89 [10]

Answer:

Options 2, 4 and 6 are True.

Step-by-step explanation:

Triangle MNO is dilated by a scale factor of $\frac{3}{2}$ centered at M(0, 6).

Rule to be followed to dilate the vertices of the given triangle,

(x, y) → (kx, ky)

Here, k = scale factor

By this rule vertices of the new triangle M'N'O' will be,

M(0, 6) → M'(0, 6) [Coordinates of M' will remain same as M because center of dilation is point M]

N(-4, -4) → N'(-6, -6)

O(6, -2) → O'(9, -3)

Option 1

M'N' is shorter than MN

Distance between M and N = $\sqrt{(0+4)^2+(6+4)^2}$

= 10.77

Distance between M' and N' = $\sqrt{(0+6)^2+(6+6)^2}$

= 13.42

Therefore M'N' > MN

Therefore, Option A is False.

Option 2

ON is shorter than O'N'

True.

Option 3

OM is longer than O'M'

False

Option 4

ON is parallel to O'N'

Since OM and MN are dilated with the same scale factor, O'N' will be parallel to ON.

True.

Option 5

OM is parallel than O'M'

Since, O'M' is the dilated form of OM,

Therefore, all the points (O, M and M') will be in a straight line.

False

Option 6

M'N' coincide with MN

True.

Therefore, Options 2, 4 and 6 are True.
