Pull out 4 from each number

9514 1404 393

Answer:

Step-by-step explanation:

Let r represent the number of hits Ricky got. Then Pedro's hits were r+281 and their total was ...

  r + (r +281) = 2679

  2r = 2398

  r = 1199

  r+281 = 1480

Pedro got 1480 hits; Ricky got 1199.

_____

Additional comment

The two answers to a "sum and difference" problem are half the sum plus or minus half the difference. Here, those values are (2679/2) ± (281/2). Pedro got more hits, so his number is (2679+281)/2 and Ricky's number is (2679-281)/2, as above.

The quotient, expressed in scientific notation, is:

Quotient = 0.36 × 10³

Given:

(2.592 × 10⁷) / (7.2 × 10⁴)

To find the quotient of 2.592 × 10⁷ and 7.2 × 10⁴ and express it in scientific notation, we divide the coefficients and subtract the exponents.

Quotient = (2.592 × 10⁷) / (7.2 × 10⁴)

Dividing the coefficients, we get:

Quotient = 2.592 / 7.2 = 0.36

Subtracting the exponents, we get:

10⁷ - 10⁴ = 10⁽⁷⁻³⁾ = 10³

In scientific notation, the coefficient should be between 1 and 10, so we can rewrite the expression as:

Quotient = 0.36 × 10³

Answer:

a = 4

Step-by-step explanation:

So your goal here is to get the variable on just one side, so add 4a to both sides.  This cancels out the 4a on of of the sides and puts a on the other side.  The new equation is 8 = -2a + 4a.  Combine like terms to get 8 = 2a.  Divide both sides by 2 to get a = 4.    You can check your work by replacing a with 4:  

8 - 4(4) = -2(4)

8 - 16 = -8

-8 = -8

Since the final result is true, (-8 does equal -8,) a = 4.

Answer:

850.9 feet

Step-by-step explanation:

The horizontal distance between Ryan and the dolphin is 850.907 feet.

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have,

Ryan is 228 feet above the water and the angle of depression to the dolphin is 15.

Using trigonometry

tan 15 = 228/ x

x= 228/ tan 15

x= 228 / 0.26794919243

x = 850.907  feet

Answer:

D. 10 units

Step-by-step explanation:

Using the distance formula:

d = √(x2 – x1)² + (y2 – y1)²

Plug in the values of the points:

d = √(3 – (-5))² + (-2 – 4)²

d = √(8)² + (-6)²

d = √64 + 36

d = √100

d = 10

Answer:

965 parts would not be defective.

Step-by-step explanation:

So for every 400 parts, 14 are defective. That means 386 are not defective. 1000 is 2.5 times as many as 400. So multiply 386 by 2.5 to get your answer.

386/1 * 5/2

193/1 * 5/1

965/1

That means for every 1000 parts, 965 would not be defective. The proportion(s) would be 386:400/965:1000 here.

The x-intercept of a function always occurs where y is equal to zero is true.

Given,

The x-intercept of a function always occurs where y is equal to zero.

We need to find whether the given statement is True or False.

The x-intercept is the point where the line passes through the x-axis.

We need to put y = 0.

The y-intercept is the point where the line passes through the y-axis.

We need to keep x = 0.

Check the statement.

The x-intercept of a function always occurs where y is equal to zero.

This is a true statement because in order to find the x-intercept we need always keep y = 0.

Thus the given statement-

The x-intercept of a function always occurs where y is equal to zero is true.
