Answer:
1. 50 m
2. 80 cm
Step-by-step explanation:
1. There are 2 triangles, subtract the area of 1 of them from the other.
The triangle that needs to be subtracted: b = 20 m, h = 10 m
A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m
The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150
150 - 100 = 50 c
2. Divide it into 3 parts:
1- 3*4 = 12
2. 7*(4 + 4) = 7*8 = 56
3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12
12 + 56 + 12 = 80 cm

When Paisley moved into a new house, she planted two trees in her backyard. At the
time of planting, Tree A was 21 inches tall and Tree B was 33 inches tall. Each year
thereafter, Tree A grew by 6 inches per year and Tree B grew by 3 inches per year. Let
A represent the height of Tree At years after being planted and let B represent the
height of Tree Bt years after being planted. Write an equation for each situation, in
terms of t, and determine the interval of time, t, when Tree A is taller than Tree B.
Answer:
At the time of planting, Tree A was 19 inches tall a When Makayla moved into a new house, she planted two trees in her backyard. At the time thereafter, Tree A grew by 6 inches per year and Tree B grew by 2 inches per year. Let Rate the tree grew every year- 6 inches per year. Equation- 6t+19.

please please my dyslexia is a pain.
Answer:
Area: 312
Perimeter: 75
Step-by-step explanation:
Area is l·w
20·16=320
two corners aren't filled
320-9-9=318
Add all the sides for perimeter
17+3+3+13+20+13+3+3=75
Answer:
281 m squared
Step-by-step explanation:
What we can first do is find the top length so we can do
17+3+3=23
then we can multiply it by the side length to get the whole rectangle
23*13=299
and we know each of the little areas is 9, and there are two so
9+9=18
and we can subtract that from the whole rectangle
299-18=281

Xavier surveyed a random sample of the grade levels of the Spanish Club members in the county. The bar graph shows the results of his survey.
The bar graph is titled Random Sample of Spanish Club Members. The horizontal axis is labeled Grade level and lists four grades: ninth to twelfth. The vertical axis is labeled Number of members from zero to fourteen by twos. Ninth, eight. Tenth, fourteen. Eleventh, five. Twelfth, three.
Of the 300 students in the Spanish Club in the county, predict how many are 9th graders
Answer:
80
Step-by-step explanation:
If you add each value it equals 30.
30x10=300 so 8 (value of the 9th grade bar) times 10 equals 80.
