Mathematics
1 answer:
devlian [24]3 years ago
6 0

Step-by-step explanation:

In the figure,

height of triangle = 10m

base of triangle/Diameter of circle = 14m

radius = 7m

Area of triangle = 1/2 × b × h

= 1/2 × 14 × 10

= 7 × 10

= 70m²

Area of semi-circle = 1/2 × pi × r²

= 1/2 × 3.14 × 7²

= 76.93m²

Area of the figure = 70 + 76.93 = 146.93m²

What is the measure of ∠S?
erma4kov [3.2K]
∠S = 360° - ∠T - ∠Q - ∠R 
∠T = 90°
∠Q = 128°
∠R = 57°
∠S = 360° - 90° - 128° - 57° = 85°
Answer: ∠S = 85°.

Harley was eating pizza and had already eaten six pieces before his sister, Samantha, got home. Samantha was worried that she wa
LUCKY_DIMON [66]

Answer:

16 pieces of pizza when the pizza was whole.

Step-by-step explanation:

You know that 6 pieces are equal to 3/8 of the pizza.

Let x represent the total number of pieces and write an equation:

3

-- times x = 6

8

Multiply each side of the equation by 8:

8 times 3

            -- x = 8 times 6

            8

3x = 48

Divide each side of the equation by 3:

3x     48

---  =  ---

3        3

x = 16

will mark brainiest I need the answer as soon as possible can you order from least to greatest and show your work
Svetlanka [38]

You have two choices: the easiest is to turn every fraction to its numerical equivalent:

-\dfrac{9}{10}=-0.9,\ \ -\dfrac{3}{7}\approx -0.42857,\ \ -\dfrac{3}{4}=-0.75,\ \ -\dfrac{6}{5} = -1.2, -\dfrac{4}{3}\approx -1.33

Now, remember that negative numbers are ordered in the opposite way with respect to positive numbers (for example, 4 is larger than 2, but -4 is smaller than -2). So, the order is

-\dfrac{4}{3} < -\dfrac{6}{5} < -\dfrac{9}{10} < -\dfrac{3}{4} < -\dfrac{3}{7}

Alternatively, you can convert all the fractions so that they have the same denominator. In this case, you will need the least common multiple of 10, 7, 4, 5 and 3, which is 420. Once you do so, you can easily order the fractions using numerators only.
