Mathematics
1 answer:
dolphi86 [110]3 years ago
4 0

Answer:

The correct option is 1.

Step-by-step explanation:

It is given than the area of the triangle ABC is 46cm².

Area of a triangle is

A=\frac{1}{2}\times base\times height

Base of the triangle is AB and height of the triangle is CD.

A=\frac{1}{2}\times AB\times CD

A=\frac{1}{2}\times AB\times 8

A=4\times AB

The area of the triangle is 46cm².

46=4\times AB

AB=\frac{46}{4}

AB=11.5

Therefore the length of side AB is 11.5 cm. Option 1 is correct.

The stem-and-leaf plot shows the scores of a class of sixth graders on a math test.
SOVA2 [1]

A stem and leaf plot shows sets of two digit numbers, by separating the ten’s place and the one’s place. On the left is the different ten’s values, while on the right next to each of the values on the left is the one’s values that associate with each of the ten’s values. This means that the numbers in this set of data are 32, 47, 51, 55, 55, 55, 58, 64, and so on. From there, you can use that knowledge to figure out how many scores were above 60.


The terms that are above 60 are 64, 65, 73, 74, 77, 87, 88, 91, 93, 93, 97, 99, and 99, for a total of 13 of the 20 scores being above 60.
