An equilateral triangle has side length 8 units. What is the area?
A. 24√3 units
B. 24 units
C. 32 units
D. 16√3 units

Answers

Answer 1

Answer:

D. 16√3

Step-by-step explanation:

To find the area, you have to find the height. To find that, you spit the triangle in half for a 30 - 60 - 90 triangle and figure out that the height is 4√3.

After you find the height, you do the equation for the area of a triangle which is 1/2 side * height, and you fill it out.

1/2 8 * 4√3

4 * 4√3

16√3

Answers

Answer: The answer is B, 5/12.

hope this helped :)

Answer:

B. 5/12

Step-by-step explanation:

2/3 x 5/8 = 10/24

The greatest common factor of 10 and 24 is 2.

Since the GCF is 2,

We divide the numerator and denominator by 2 and get 5/12.

Therefore, the simplified fraction of 10/24 is 5/12.

n a study to investigate whether vitamin C will prevent colds, 400 subjects are assigned at random to one of two groups. The experimental group takes a vitamin C tablet daily, while the control group takes a placebo. At the end of the experiment, the researchers calculate the difference between the percentage of subjects in the two groups who were free of colds. This difference is statistically significant (P=0.03) in favor of the vitamin C group.

Answers

Answer:

Step-by-step explanation:

The aim of this question is to see if we can infer and conclude that vitamin C has a good impact in preventing colds based on the evidence provided.

Null hypothesis: Vitamin C has no effect on preventing colds.

Alternative hypothesis: Vitamin C has a strong effect on preventing colds.

Assuming, significance level = 0.05

Since the p-value for the difference is 0.03 which is less than 0.05.

Hence, the null hypothesis is rejected (which is there is no effect of vitamin C).

As a result, it can be concluded that Vitamin C has a major impact on the prevention of colds.

Answers

Answer:

[tex] \bf \large 20 \: inches [/tex]

Step-by-step explanation:

Given that :

The radius of a circle is 2.9 in.

to find :

Find the circumference to the nearest tenth.

formulas used :

circumference = 2 × π × r

where,

π = 22/7r = 2•9 inches

explanation :

⟼ c = 2πr

⟼ c = 2 × 22/7 × 2•9 inches

⟼ c = 2 × 3•14 × 2•9 inches

⟼ c = 6•28 × 2•9 inches

⟼ c = 18•21 inches.

Round to the nearest tenth :

⟼ c = 18•21 inches

⟼ c = 20 inches

∴ circle circumference is 20 inches .

6 tortillas

Step-by-step explanation:

hope this helps and is right. p.s. i really need brainliest :)


Well, first we multiply every ingredient in the recipe amount by 3, because 6 x 3 = 18. Then we’ll subtract what we have from what we need.

500 x 3 = 1500g of chicken
600 x 3 = 1800g of peppers
90 x 3 = 270g of onion
25 x 3 = 75g of spice mix
12 x 3 = 36 tortillas

Chicken: needs 1500, has 900
1500 - 900 = 600g more chicken needed

Peppers: needs 1800, has 1200
1800 - 1200 = 600g more peppers needed

Onion: needs 270, has 150
270 - 150 = 80 g more onion needed

Spice mix: needs 75, has 60
75 - 60 = 15g more spice mix needed

Tortillas: needs 36, has 30
36 - 30 = 6 more tortillas needed

A muralist is painting the side wall of a building. The wall is shaped like a rectangle that is 60
feet long and has a diagonal length of 68 feet. If a gallon of paint can cover 800 square feet,
how many gallons will the muralist use?

Answers

Answer:

2.4 gallons

Step-by-step explanation:

to answer this question :

we have to determine the width of the rectangle.

determine the area

determine the gallons needed

Pythagoras theorem would be used to determine the width of the wall

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = hypotenuse

60² + b² = 68²

3600 + b² = 4624

b = ²4624 - 3600 = 1024

√b = 32

Area of a rectangle = length x width

32 x 60 = 1920

Gallons needed = 1920 / 800 = 2.4 gallons
