Answer:

x=7 (if your teacher cares it could + or - 7)

Step-by-step explanation:

Okay, since it's a 90 degree triangle you can use the Pythagorean theorem

( a^2 + b^2 = c^2)

Since it's an isosceles triangle the other side is x because it's the same value.

x^2 + x^2= (7[tex]\sqrt{2}[/tex] )^2

Add the left side

2x^2= 7^2 + [tex]\sqrt{2}[/tex]^2 roots and square roots cancel each other out

So -> 2x^2= 49 x 2 =98

just solve for x.

x^2 = 98/2

x^2= 49

Square root both sides

x= 7

Answer:

98 guests

Step-by-step explanation:

First, you would take the amount of money available, $3,300.00, and subtract the cleanup fee ($50) from that.

You would get $3,250

Next, you divide $3,250 by the amount of money per guest ($33).

Your total is 98.48 repeated

That rounds to 98 people, since you can't go over.

Hope this helps you!

Answer:

24, 12, 12

Step-by-step explanation:

I do not understand the question, but I believe you gave us how many vowels and consonants are in a word. Then you asked us for how many of them were in 6 words, which is simple math of 4 times 6. I don't get the last part, but I think you asked how many consonants in 6 words, and how many vowels in six words, another simple math question, 2 times 6.

In the English language, 5 letters are typically considered vowels: a, e, i, o, and u, with 2 additional letters, y, and w, that can sometimes act as vowels or consonants depending on their position in a word. To find out how many vowels and consonants there are in six words, we need more information about the specific six words.

To find out how many vowels and consonants there are in six words, we need more information about the specific six words. If each of the six words has 2 vowels and 2 consonants, then the total number of letters in the six words would be 6 x (2 + 2) = 24.

38%

It is 38% because 35/93 is like 0.3775942

Answer:

38%

Step-by-step explanation:

1. add the number of rain and snow days

[tex]24+11=35[/tex]

2. divide by total number of days

(total amount of days: 93)

[tex]\frac{35}{93}[/tex] [tex]=.376[/tex]

rounds to .38

3. multiply by 100 to get it as a percent

[tex](.38)(100)=38%[/tex]

4 miles : 1 hour

1 mile : x hours

x/1 = 1/4

x = ¼ hours

¼ hours = ¼ × 60 = 15 mins

Answer: 15 minutes

Step-by-step explanation: 1 hour is 60 minutes, 60 minutes divided by the 4 miles will give you 15 minutes.

Answer:

x = 8

Step-by-step explanation:

28 = 2(x + 6)

28 = 2x + 12

28 - 12 = 2x

16 = 2x

16/2 = x

8 = x

x = 8

Answer:

D. 2(x + 6) + 2x = 28

Answer:

0xFD

Step-by-step explanation:

To convert 253 into hexadecimal, divide the number by 16 repeatedly and record the remainders.

To convert 253 into hexadecimal, you need to divide the number by 16 repeatedly and record the remainders. The most significant digit of the hexadecimal representation will be the last remainder obtained. So, let's proceed:

Therefore, 253 in hexadecimal is DF.

By using the congruent angle relationships formed by transversal cutting parallel lines, we can infer that only lines t and v are parallel to line s, as they form corresponding angles of 89 degrees with transversal r, unlike line u, which forms a 91-degree angle.

The information given in the question indicates that a transversal r cuts four lines s, t, u, and v. By the information given for the angles formed by this transversal with each line, we can determine which lines are parallel to line s using the concept of alternate interior angles and corresponding angles, which are congruent if the lines are parallel  Since the angle formed by the transversal and line s is 89 degrees and a corresponding angle formed by the transversal and line t is also 89 degrees, we can say that line s is parallel to line t.

Similarly, since another angle formed by transversal and line v is also 89 degrees, it implies that line s is also parallel to line v. However, line u has an angle of 91 degrees formed by the transversal, which does not match the 89-degree angle formed by the transversal with line s, indicating that line u is not parallel to line s. Given this information, the lines parallel to line s are only line t and line v.

23 1/24

Step-by-step explanation:

70 1/3 minus 24 1/4 divided by 2

To find the values of x such that y is less than 0 in the equation y = |x + 2| - 1, we set y less than 0 and solve for x. The values of x that satisfy y < 0 are x < -1.

To find the values of x such that y is less than 0, we need to determine the portion of the graph below the x-axis, since y is negative in that region. Given the equation y = |x + 2| - 1, we can set y less than 0 and solve for x.

Setting y = 0, we have 0 = |x + 2| - 1. Adding 1 to both sides, we get 1 = |x + 2|. When the expression inside the absolute value is positive, the absolute value will be the same. Therefore, we can write x + 2 = 1. Solving for x, we get x = -1.

So, the values of x such that y is less than 0 are x < -1.

Answer:

There will be 3472 cats in 10 years

Step-by-step explanation:

There were 3500 cats

The number of dogs in a city is declining at a rate of about 0.08% each  year.

We are supposed to find the no. of cats in 10 years

Formula :[tex]N(t)=N_0(1-r)^t[/tex]

Where N(t) = Remaining cats after t days

[tex]N_0[/tex] = Initial population

r = rate of depreciation

t=time

So, No. of cats remained after 10 years = [tex]3500(1-\frac{0.08}{100})^{10}=3472.100[/tex]

Hence There will be 3472 cats in 10 years

Answer:

x= (-3i-√3)/2

x= (3i+√3)/2

Step-by-step explanation:

you have to use the quadratic formula which is (-b±√b^2+4ac)/2(a)

a=1

b=3

c= -3

when you plug the numbers into the formula, you get a negative in the square root, so you have to bring out an Imaginary number which is i and connect it with your -b value.

in this case, you only have to switch out the plus and the minus strictly because of the imaginary number

Answer:

$90.10

Step-by-step explanation:

price of the skateboard = $85

sales tax = 6%

Dollar value of sales tax  = 6% of price of the skateboard

  = 6% of $85 = (6/100) * $85 = ( 6* 85)/100 =  $ 5.10

Total cost of the skateboard = price of the skateboard + sales tax value

substituting the value of price of the skateboard and  sales tax value, calculated above, we have

  Total cost of the skateboard =  $85 +   $ 5.10 = $90.10
