Answer:

9 × 10⁻⁴

Step-by-step explanation:

A number in scientific notation has the form A × 10ⁿ.

A is a number from 1 to 10, but not 10 itself and is called the coefficient.

n is an integer and is called the exponent.

10 000 has four zeros, so the exponent is 4.

However, your number is 9 ten thousandths, or 9/(10 000).

When the powers of 10 are in the denominator, the exponent is negative. In this case, the exponent is -4.

In scientific notation,

9 ten thousandths = 9 × 10⁻⁴

Answer:

Step-by-step explanation:

intial vaule (or at 0 x) is 10 so we have

y=? + 10

and for every hour (x) we charge 4 dollars (same as multiplying 4 by the amount of hours)

so y=4x+10 or y=10 + 4x

David has 3 1/2 cups of blueberries. He uses 1/4 of a cup of blueberries to make a breakfast smoothie. He uses 1/2 of the remain

dusya [7]

Answer:

$1\frac{5}{8}$ cup of blueberries

Step-by-step explanation:

Since David starts out with 3 1/2 cups of blueberries and uses 1/4 cup to make a smoothie, we will need to subtract 1/4 from his starting amount of 3 1/2

$3\frac{1}{2}-\frac{1}{4} =3\frac{1}{4}$ David now has 3 1/4 cup of blueberries

David then uses half of this new amount of blueberries to make his pancakes. We will need to divide by 2 in order to figure out how much half is

First we can turn 3 1/4 into an improper fraction to make it easier to work with → 3 1/4 = 13/4
Now dividing 13/4 by 2 gives us $\frac{\frac{13}{4} }{2} =(\frac{13}{4})(\frac{1}{2}) = \frac{13}{8}$
David used 13/8 cups of blueberries to make his pancakes
Turning this back into a mixed number leaves him with 1 5/8 cup of blueberries

In the diagram below, BD is parallel to XY. What is the value of x? 76 y

Butoxors [25]

Answer:

x = 76°

Step-by-step explanation:

Corresponding angles are formed when a transversal line cuts across two parallel lines. The angles formed are in corresponding position close to the transversal. Corresponding angles formed like this are congruent.

In the diagram given above, BD and XY are parallel lines cut across by a transversal line.

Angle labelled x corresponds with the angle measuring 76°. Therefore they are both congruent. Thus: x = 76°.
