A triangle has angle measurements of 56°, 54°, and 70°. What kind of triangle is it?

Answers

Answer 1

Answer and Step-by-step explanation:

The answer is acute.

Acute angles are angles that have a degree that is less than 90 degrees.

Obtuse angles are angles that have a degree that is more than 90 degrees.

Right angles are angles that are 90 degrees.

Our triangle has all angles that are less than 90 degrees, so it is an acute triangle.

Elise is investing 10,000 in an account that earns 2.25% simple interest. How many years will it take to have a balance of 12,700 in her account, if she does not add or withdraw from the account?

Answers

Answer:

12 years

Step-by-step explanation:

The formula to solve the above question i.e to find the time is given as:

Equation:

t = (1/r)(A/P - 1)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2.25%/100 = 0.0225 per year,

then, solving our equation

t = (1/0.0225)((12700/10000) - 1) = 12

t = 12 years

Therefore, if she does not add or withdraw from the account, the time it

will take to have a balance of 12,700 in her account is 12 years

There were 80 runners to start a race. In the first half of the race, 1/5 of them dropped out. In the second half of the race, 5/8 of the remaining runners dropped out. How many runners finished the race

Answers

Answer:

Step-by-step explanation:

Initially, there were 80 runners in the race. After the first half, 1/5 of them dropped out (given). Therefore, 4/5*80=64 runners remain. In the second half, 5/8 of these 64 runners drop out, meaning 3/8*64=24 runners finished the race.

Alex had 806 dinosaurs. There were 102 Velociraptors, 243 Tyrannosauruses, and the rest were Brontosauruses. There were twice as many eggs as dinosaurs. How many eggs does Alex have?

Answers

Answer: 1,612 eggs

Step-by-step explanation:

Alex has a total of 806 dinosaurs. He also has twice as many eggs as he does dinosaurs.

CE = x

EB = 15

AE = 9

ED = 10

Write the equation for a radical function that has been flipped left and shifted down 1.

Answers

Answer:

[tex]g(x)=\sqrt{-x}-1[/tex]

Step-by-step explanation:

Let's use the parent function [tex]f(x)=\sqrt{x}[/tex] as an example

Because we are flipping the radical function left, this means [tex]f(x)=\sqrt{-x}[/tex]

Because we are shifting down 1 unit vertically, we have [tex]g(x)=\sqrt{-x}-1[/tex]

Therefore, the final function is [tex]g(x)=\sqrt{-x}-1[/tex]

Find the area of each semicircle. Round to the nearest tenth. Use 3.14 for Pi. 1. Diameter = 9.4 mm 2. Radius = 3 1/2 ft 3. Radius =8 in

Answers

Answer:

34.68 mm^2

19.23 ft^2

100.48 in^2

Step-by-step explanation:

Area of a circle = 0.5 x nr^2

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

0.5 x (9.4/2)^2 x 3.14 = 34.68

0.5 x (3.5)^2 x 3.14 = 19.23 ft^2

0.5 x (8)^2 x 3.14 = 100.48 in^2
