Answer:

answer is 4

Step-by-step explanation:

we need to find the width of the larger rectangle: 100/20=5

and then find the scale between them

20/4=5

and use the width to divide by that, and you will get the width for the smaller shape, which is 5/5=1

1*4=4

The angle bisector of ∠ACD in rhombus ABCD makes a 64° angle with the diagonal BD. Find the measure of ∠BAD.

saveliy_v [14]

The complete question in the attached figure

we know that
the diagonals of a rhombus intersect to form right angles,
so
angle ACE is ----------> (90°-64°)-----------> 26°
ACE is the angle bisector of ACD, this means that ACD is ---------> 26 x 2 = 52°

The diagonals are angle bisectors to the opposite corners
so
ACD = ACB = 52°
and
BCD = 52 x 2 = 104°
For a rhombus, opposite angles are equivalent,
so
BAD = BCD = 104°

the answer is
angle BAD=104°

Answer:

2 and 3

Step-by-step explanation:

2) If two polygons are similar, the ratio of their areas is equal to the square of the ratio of their corresponding sides.

side ratio: 1/4------- area ratio: 1²/4² = 1/16 = 1:16 ratio

3)If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths.

The ratio of the perimeters is the same as the scale factor.

scale 1:4

A stem-and-leaf plot for the number of homeruns hit by 30 high school teams is shown. find the probability that a team chosen at

pantera1 [17]

To answer this you need to read the stem and leaf lot and determine how many values were over 28., Or how many were less than or at 28 and subtract it from 30.

There are 10 teams at 28 or less, so 20 teams are above 28.

The number to the left of the | tells us the tens place of the set of number that come after it.

For example 2|4 7 8 stands for 24, 27, and 28.

If 20 out of 30 were above 28 homeruns, then your probability is 20/30 or 2/3 or 0.667.

Step-by-step explanation:

A ratio is a comparison of two quantities. You could represent how many diet sodas there compared to how many regular sodas as a ratio.

I think you were trying to ask about the Flocabulary question, right?

I had it too and got it correct.
