A scale has a percent error of 5%. The actual mass of a rock is 258 g.

Semmy [17]

The scale is likely to show the mass is either 270.9g or 245.1g

Step-by-step explanation:

Actual mass = 258g

Percent error = 5% = ±0.05

Mass shown by scale = Actual mass*percent error

$Mass\ shown\ by\ scale=258*(\±0.05)\\Mass\ shown\ by\ scale=\±12.9g$

Therefore,

Mass shown by scale = 258+12.9 , Mass shown by scale = 258-12.9

Mass shown by scale = 270.9g , Mass shown by scale = 245.1g

The scale is likely to show the mass is either 270.9g or 245.1g

WILL MARK BRAINLIEST! PLEASE HELP MEH! Find the area

Alenkasestr [34]

In this problem, you are asked to solve the area of a trapezoid. The formula in finding the area of a trapezoid is:

A = [(a + b)/2] x h

Where a = base 1

b = base 2

h = height

Substituting the given measurements to the formula:

A = [(6.9 km + 2.7 km)/2] x 2.2 km

A = (9.6 km/2) x 2.2 km

A = 4.8 km x 2.2 km

A = 10.56 km^2

Therefore, the area is 10.56 square kilometers.

If line T is a transversal of lines I and m, name the angel relationship of the given angle pairs

kolbaska11 [484]

Answer:

a. corresponding angles (congruent)

b. alternate exterior angles (congruent)

c. same-side interior angles (supplementary)

Step-by-step explanation:

The vocabulary associated with angles created by a transversal and parallel lines is not so difficult.

If angles are on the same side of the transversal, they are same-side angles. If not, they are alternate angles.

If angles are between the parallel lines, they are interior angles. If not, they are exterior angles.

If the angles are in the same direction from the point of intersection of the transversal with the parallel line, they are corresponding. Corresponding angles are same-side; one is interior and the other is exterior.

These names generally apply to angles with different vertices.

a. Both angles are northwest of the intersection point; they are same-side, and one is interior and one is exterior. They are corresponding angles. (congruent)

b. The angles are on opposite sides of the transversal and are outside the parallel lines. They are alternate exterior angles. (congruent)

c. The angles are on the same side of the transversal, and both are between the parallel lines. The are same-side interior angles. (supplementary)

Select the multiplication sentence that applies the associative property of multiplication to the example. Example: 6 × (4 × 2)

Sliva [168]

answer : D

A. (6 × 7) + 6 = 48

Associative property of multiplication . Here we have +6 . there is a + sign inbetween. so it does not comes under Associative property of multiplication

B. 6 × (4 + 2) = 36

Here we have 4 +2 . there is a + sign inbetween. so it does not comes under Associative property of multiplication

C. (6 + 4) × 2 = 20

Here we have 6 + 4 . there is a + sign inbetween. so it does not comes under Associative property of multiplication

D. (6 × 4) × 2 = 48

Here we have 6 times 4 times 2. so it comes under Associative property of multiplication
