Answer:

You may use cos 60° or sin 30°. Let's use cos 60°.

cos 60° = opp/hyp = (2 mm)/j

j = (2 mm)/(cos 60°) = 4 mm

What is the probability that a randomly chosen four-digit integer (no leading zeros) has distinct digits and ends with the digit

S_A_V [24]

Answer:

c. 0.0498

Step-by-step explanation:

First of all, let us find the number of four digit numbers possible.

There are 4 digits and let us have a look at the possibility of each digit.

Number of possible options for Unit's digit = 10

Number of possible options for ten's digit = 10

Number of possible options for hundred's digit = 10

Number of possible options for thousand's digit = 9 (because 0 can not be there to make it a 4 digit number)

Total number of possible outcomes = $10\times 10\times 10\times 9 = \bold{9000}$

As per the given condition, unit's digit is 7.

So, number of possible options for unit's digit = 1

Number of possible options for thousand's digit = 8 (7 and 0 can not be there to make it a 4 digit number)

Number of possible options for hundred's digit = 8 (7 and one digit used in thousand's place can not be there)

Number of possible options for ten's digit = 7 (7, two digits used at thousand's and hundred's places)

Number of possible outcomes as per given conditions = $1\times 8\times 8\times 7 = \bold{448}$

Formula for probability of an event E can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

$P(E) = \dfrac{448}{9000} =\bold{0.0498}$

What is the length of the hypotenuse?

Charra [1.4K]

Answer:

Hello! answer: 85

Step-by-step explanation:

68 × 68 = 4624

51 × 51 = 2601

4624 + 2601 = 7225

√7225 = 85

85 × 85 = 7225 therefore c = 85 Hope that helps!

In the diagram, the length of segment BC is 23 units. What is the length of segment DC? 3 units 8 units 13 units 33 units

Maksim231197 [3]

based on the drawing both sides are the same length

so knowing BC = 23 you need to find the value of x and put it in the formula for the side

23=2x+7

16 = 2x

x=8

4x+1 = 4(8)+1 = 33 units

Shelly wrote the following number in expanded form. 90,000+600+8.how would she write the number in word form?

murzikaleks [220]

The number 90,000+600+8 in word form is Ninety thousand six hundred and eight.

<u>SOLUTION: </u>

Shelly wrote the following number in expanded form. 90,000+600+8.

We have been asked to write the number in word form.

The number has been expanded into ten thousand, hundred and ten with additive mathematical operator in between.

So, the given number can be written as follows:

90,000 = ninety thousand.

600 = six hundred

8 = eight.

But if we add the numbers together, we have:

=90,000+600+8.

=90,608

So, on putting the number in word from we get:

Ninety thousand six hundred and eight
