Answer:
x is 6 degrees
Step-by-step explanation:
so its 90 degress, how do i know? because it is parrallel to the one with a half square (the 90 degrees) so we equal the angels to 90 because they are equal to 90 (sorry if it sounds confusing, if you want i can still explain more later)
7x + 8x = 90
15x = 90
x = 90/15
x = 6
Answer:
See Below.Explanation:
Both the angles lie inside a right angle, whose total sum is 90 degrees.
Solve:
7(x) + 8(x) = 90°15(x) = 90°x = 6°Each of the angle:
7(x) ⇒ 7(6) = 42°8(x) ⇒ 8(6) = 48°

Ben runs 3/4 mile each day.How many Miles Does ben run in 12 days
Answer:
9 miles
Step-by-step explanation:
0.75x12=9
or
75x120=90
90/10=9
If Ben runs 3/4 mile each day than he runs 9 miles in 12 days.
To find out how many miles Ben runs in 12 days
we need to multiply the distance he runs each day (3/4 mile) by the number of days (12).
First, let's convert 3/4 mile to a decimal:
3/4 mile = 0.75 mile
Now, we can calculate the total distance Ben runs in 12 days:
0.75 mile × 12 days
= 9 miles
Therefore, Ben runs 9 miles in 12 days.

please help me out with these two problems
find X and Y
Answer:
Step-by-step explanation:
I'll work on the left triangle first:
tan 20 = x /10
x = 10tan 20 = 3.64
cos 20 = 10/y
y = 10/cos20 = 10.64.
tan 70 = 12/x
x = 12/tan 70 = 4.37.
sin 70 = 12/y
y = 12/sin70 = 12.77.

can some help me out with this EXTRA POINTS!!
Answer: ≈ 185.73009
Step-by-step explanation:
area of square: [tex]length^{2}[/tex]
area of circle: [tex]\frac{radius^{2} * \pi }{y}[/tex]
length: 15
radius = diameter/2
radius: 5
area of square - area of circle = area between square and circle:

What is the rule and how do you find n? 100 points to answer!
Answer:
n = 17
Rule: y = 2x + 1
Step-by-step explanation:
By inspection of the first two ordered pairs in the given table, it appears that for each 1 unit increase in x, y increases by 2 units.
To check this, write the ordered pairs with 5 ≤ x ≤ 10 using this rule:
(5, 11) (6,13) (7, 15) (8, 17) (9, 19) (10, 21)
As the ordered pair (10, 21) appears in the table, then we can confirm that this is the rule and that it is a linear function.
If y increases by 2 units for every 1 unit increase of x, then the slope of the linear function will be 2.
Using the point-slope form of a linear function: [tex]\sf{y-y_1=m(x-x_1)}[/tex]
(where m is the slope and [tex]\sf(x_1,y_1)[/tex] is a point on the line)
Given:
m = 2[tex]\sf(x_1,y_1)=(5,11)[/tex]Substituting these values into the formula:
[tex]\implies \sf{y-11=2(x-5)}[/tex]
[tex]\implies \sf y=2x+1[/tex]
Therefore, the rule is [tex]\sf y=2x+1[/tex]
To find n, simply substitute x = 8 and y = n into the equation:
[tex]\implies \sf n=2(8)+1=17[/tex]
Therefore, n = 17
Take 2 points and form equation
(5,11)(6,13)Slope:-
m=13-11/6-5=2Equation in point slope form
y-11=2(x-5)y-11=2x-10y=2x+1So

square inches. Find the
Slant height of the
pyramid.
The slant height of the square pyramid that has a surface area of 304 sq. in. is: 16 inches.
What is the Surface Area of a Square Pyramid?Surface area (SA) = a² + 2al
Given the following parameters:
Surface area = 304 sq. in.a = 8 in.l = ? (slant height)Plug in the values into (SA) = a² + 2al:
304 = 8² + 2(8)l
304 = 64 + 16l
304 - 64 = 16l
240 = 16l
240/16 = l
15 = l
l = 16
Therefore, the slant height of the square pyramid that has a surface area of 304 sq. in. is: 16 inches.

Answer:
y = 0
Step-by-step explanation:
the midline is positioned midway between the maximum and minimum values of the function.
maximum = 0.5 and minimum = - 0.5 , then
y = [tex]\frac{0.5-0.5}{2}[/tex] = [tex]\frac{0}{2}[/tex] = 0
the equation of the midline is y = 0 ( that is the x- axis )

You are starting a savings account for college. You put $1,000 in as your starting balance. You earn simple interest at 10% every year. You also must pay 30% income tax on the interest earned annually. Calculate the balance for the account after 5 years
Answer:
$1,350
Step-by-step explanation:
Simple interest formula
I = Prt
where:
I = interestP = principalr = interest rate (in decimal form)t = time (in years)Given:
P = $1,000r = 10% = 0.1t = 5 years⇒ Total interest earned = 1000 × 0.1 × 5 = $500
If you have to pay 30% income tax on the interest earned annually, then you will keep 70% of your earned interest.
⇒ 70% of $500 = 0.7 × $500 = $350
Account balance = principal + interest earned after tax
= $1,000 + $350
= $1,350

There are 3 pies, the total amount of slices before they were eaten is 12. If you add the slices left..3+3+3 that would be 9
Answer:
D: 2 1/4
Step-by-step explanation:
I'm not really sure though. But since there are 3 apple pies if you take one slice from one of the pies and add it to another pie it will make one whole pie and then after there is one whole pie you do the same to another pie and their is 2 whole pies and their is one slice remaining and there is 4 whole slices in a whole pie so there fore I'm guessing that the answer is 2 1/4
