Answer: D- 97.4
Step-by-step explanation:
For the scale factor of 1:3. Use ratio and proportion to solve for the area of the triangle.
area of triangle RST/ area of triangle XYZ = (1/3)^2
where
area of traianlge RST = 10.825 inch^2
Area of triangle XYZ= Area of triangle RST x (3)^2
Substitute the given values=97.4 inch^2
Answer:
Step-by-step explanation:
length=4×28=112 mm=11.2 cm
three centers form an equilateral triangle each side=2×28=56mm=5.6 cm
to find the height
h=√(5.6²-2.8²)=2.8√3
width=2.8+2.8√3+2.8=5.6+2.8√3=2.8(2+√3)
area=11.2×2.8(2+√3)≈117.03 7cm²≈117 cm²
First we need to identify if the data is qualitative or quantitative.
The data is average number of people living in the homes.
Qualitative data as its name indicates is an attribute or characteristic. It can not be measured e.g color. Quantitative data is such a data which can be counted or measured.
Since the average number of people can be counted and measured, the data is Quantitative.
In an observational study the individuals are observed. In the given case, Kira did not observed the individuals to gather the data, rather she used an Online resource to gather the data.
Therefore, the correct answer will be:
Kira used published data that is quantitative.
Answer:
hello
Step-by-step explanation:
y⁰ is equal to 90⁰,because 360⁰/4=90
interior angles of triangle=180⁰
then,
90⁰+32⁰=122⁰
180⁰-122⁰=58⁰
90⁰-58⁰=32⁰
x⁰ is equal to 32⁰
hope it helped
have a nice day
