Answer:

26 miles.

Step-by-step explanation:

To solve this problem, the Pythagorean theorem must be applied, which states that the hypotenuse squared of every right triangle is equal to the sum of its squared legs, that is, A^2 + B^2 = C^2 .

Therefore, applying this formula, to determine the distance in a straight line from the starting point to the driving end point, the following calculation must be performed:

24^2 + 10^2 = X^2

576 + 100 = X^2

√676 = X

26 = X

Thus, the distance between the two points is 26 miles.

Maria invested $450 in a savings account and earned $126 in interest at the end of 7 years.
Brut [27]
The interest rate is B. 4%

Given:
Principal = 450
Interest = 126
term = 7 
rate = ?

Simple Interest is computed by multiplying the Principal, rate, and term.

Interest = P × r × t

126 = 450 × r × 7
126 = 3150r
r = 126/3150
r = 0.04 x 100% = 4%

To check:

I = 450 
× 0.04 x 7
I = 18 × 7
I = 126

You increase the size of a computer screen display by 20%. Then you decrease it by 20%. What is the size of the computer screen
lutik1710 [3]

Answer: The size of computer display after 20 % increase and then 20 % decrease= 96 % of the original size.


Step-by-step explanation:

Let the original size of computer be 100x , then if it increases by 20 %

then the new size of the computer=100x +20% of 100x

=100x+\frac{20}{100}\times100x\\=100x+20x\\=120x

The size of computer after 20% increase= 120x

If size of computer is decreased by 20 % then

The new size of computer= 120x - 20% of 120 x

=120x-\frac{20}{100}\times120x\\=120x-24x\\=96x

On comparing it to the original size , we get

\frac{96x}{100x}\times100=96\%

Thus, the size of computer display after 20 % increase and then 20 % decrease= 96 % of the original size.

Answer:

Answer:

Total number of cards = 32(4) or y=32(4)

Roberto had 128 cards.

Step-by-step explanation:

Consider the provided information.

Part (A)

He gave his four friends 32 baseball cards each.

Let the number of cards he have before giving them to his friends is y.

This can be written as:

y = 32(4)

Part  (B)

Now solve the above equation as shown.

y = 32(4)

Multiply 32 with 4

y = 128

Hence,  Roberto had 128 cards.
