2 answers:

7 0

The answers are 3. right, and 5. isosceles. It is a right triangle because any triangle with a 90 degree angle is a right triangle, and it is isosceles because its two other angles, 45 and 45 degrees, are equal, meaning that their legs are the equal length as well.

3. Right
5. Isosceles

Isosceles triangles have 2 sides measuring the same length and a right triangle contains a 90 degree angle

Sarah had invested $800 in a savings account that paid 4.2% interest compounded annually. How much money was in the account afte

Answer: $943.11

Step-by-step explanation:

Compound Interest formula is: $A=P(1+r)^t$ where

A is the Accrued amount (total earned)
P is the Principal (amount initially invested)
r is the interest Rate (convert percent to a decimal)
t is the Time (number of years)

It is given that; P = 800 r = 4.2% (0.042) t = 4

A = 800(1 + 0.042)⁴

A = 800(1.042)⁴

A = 943.106 → A = 943.11 (rounded to the nearest penny)

Sarah invested $800 for four years at an interest rate of 4.2% and accrued $943.11

The two tables give the number of pints of red and blue paint that are used to make different amounts of two shades of purple pa

ValentinkaMS [17]

The two highlighted rows show that for the same amount of blue, Purple #1 uses more red than Purple #2.

This means that Purple #1 is a redder shade of purple than Purple #2.

Purple #2 is a bluer shade of purple than Purple #1.

Step-by-step explanation:

The two highlighted rows show that for the same amount of blue, Purple #1 uses more red than Purple #2.

Making blue's quantity as 3 parts for purple #1 implies red part becomes 1.5 to maintain the ratio 1:2

Purple #1 has 1/3 parts red and 2/3 parts blue. Purple #2 has 1/4th part red and 3/4th part blue.

Hence, Purple #1 is a redder shade of purple than Purple #2.

From the above explanation, Purple #2 is a bluer shade of purple than Purple #1.

Sure hopes this helps you :)

Answer:

The answer is B) 1/25

Step-by-step explanation:

This is because given that f(x) = 5^x

Hence, f(-2) would be 5^-2, which is equal to (1/5^2) => 1/25

Because a^-b can be written as 1/a^b
