Kenneth shared a basket of apples with three of his friends. The basket weighed 14.75 pounds. What is the weight of the apples t
Elena-2011 [213]

Answer:

Assuming each person gets the same amount of apples, each friend gets 3.6875lbs of apples.

Step-by-step explanation:

Now in order to find this, we need to note that 4 people get apples (Kenneth and 3 friends). So we take the total number of pounds and divide it by 4.

14.75lbs/ 4 people = 3.6875lbs per person

A boy, who is 5ft. 6in y’all, casts a shadow 2ft long. Find the height of the pole if it casts a shadow 2 yards long
MArishka [77]

Answer:16 ft 4 in


Step-by-step explanation:we want to find the height of the pole.

It's shadow is 2yards(6ft) long,

3 x the boy's shadow of 2ft long

Because the length of a shadow corresponds to the height of the object casting it, the poles height would be 3x the height of the boy.

His height is 5'6" (66")

66×3=196

196" = 16'4"

Which transformation will map an isosceles trapezoid onto itself? rotation by 180° about its center, reflection across a diagona
alukav5142 [94]

Answer:

The correct option is 4.

Step-by-step explanation:

The non parallel sides of an isosceles trapezoid are congruent.

The image of an isosceles trapezoid is same as the preimage of isosceles trapezoid if

1. Reflection across a line joining the midpoints of parallel sides.

2. Rotation by 360° about its center.

3. Rotation by 360° about origin.

If we rotate the trapezoid by 180° about its center, then the parallel sides will interchanged.

If we reflect the trapezoid across a diagonal, then the resultant figure will be a parallelogram.

If we reflect across a line joining the midpoints of the nonparallel sides, then the parallel sides will interchanged.

After rotation by 360° about the center, we always get an onto figure.

Therefore option 4 is correct.

Points A, B, C, and D are the vertices of a square. Points E and F are the center of two congruent semicircles that are tangent
Masja [62]

Answer:

8 sq units

Step-by-step explanation:

to find the area of shaded region:

area of square minus sum of areas of each semi-circle

A(square) = 6² = 36

A (semi-circle) = πr²/2

= π3²/2

= 4.5π

Since there are two semi-circles, that makes one complete circle with an area of 9π

A(circle) ≈ 28 sq units

36-28 = 8 sq units
