A right triangle has one angle that measures 15º. What is the measure of the other acute
angle?
Answer:
75°
Step-by-step explanation:
The sum of interior angles of a triangle is 180°Right angle = 90°Acute angle is an angle that measures less than 90°
Let x = unknown angle
Therefore, if a right triangle has one angle that measures 15°:
⇒ x + 15 + 90 = 180
⇒ x + 105 = 180
⇒ x = 180 - 105
⇒ x = 75°
[tex] \bigstar \underline\frak{Required \: Solution}[/tex]
[tex] \\ [/tex]
Given :-
Triangle is a right triangleOne angle of triangle = 15°[tex] \\ \\ [/tex]
To find :-
Left angle of triangle.[tex] \\ \\ [/tex]
So first you should know what is right triangle ?
A triangle which has one angle as 90° and other two angles are acute angle.
[tex] \\ [/tex]
So we get know that one angle of triangle is 90°
Now :-
[tex] \star \boxed{\angle 1 + \angle 2 + \angle 3 = 180\degree}[/tex]
Reason :-
Sum of angles of triangle is equal to 180°
Formula :-
sum = (no. of angles - 2) × 180°Sum = (3 - 2) × 180°Sum = 1 × 180°Sum = 189°[tex] \\ \\ [/tex]
Steps to find left angle :-

In an exam Ashley secured 332 marks. If she secured 83 % makes, find the maximum marks.
Answer:
Maximum = 400 marks
Step-by-step explanation:
Given :-
332 marks
83% of the marks
To Find :-
Total marks (T)
Solving :-
T x 83% = 332
T x 83/100 = 332
83T = 33200
T = 33200/83
T = 4 x 100
T = 400 marks
Solution :-
Maximum = 400 marks
To number a book from 1 up to its last page took 552 digits. How many pages are in the book?
Explanation:
So 552 digits are used to number the pages of a book consecutively from page one. How many pages are there in the book?
1 to 9 = 9 digits
10 to 99 = 2*90 = 180 digits
So, 1 to 99 uses 189 digits.
552 - 189 = 363
3 digits per page = 363/3 = 121 pages starting at page 100.
Page 100 to 220 is 121 pages
220 pages in total
I hope this is logic is right - you might want a second opinion, too.
The number of the pages in the book which has a number from 1 to 552 digits will be 220.
What is Algebra?Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
To number a book from 1 up to its last page took 552 digits.
Then the number of pages in the book will be
1 to 9 there are 9 digits.
From 10 to 99, the number of digits will be
2 × 90 = 180
10 to 99 there are 180 digits.
From 1 to 99, there are 189 digits.
Then the remaining digits will be
552 – 189 = 363
Three digits per page will be
363/3 = 121
Page starting at hundred.
Then the total number of pages will be
120 + 100 = 220

The scale ratio of a model is the proportionate ratio of the model's linear dimensions to the equivalent characters. The actual mural will be 5 inches wide and 11 inches tall.
What is the scaling ratio?The scale ratio of a model is the proportionate ratio of one of the model's linear dimensions to the equivalent characters in the original.
As it is given that Arnold is using a scale in which 12 inches represents 1 foot to paint the mural. but since we know that 12 inches are equal to 1 foot.
Therefore, the actual mural will also be 5 inches wide and 11 inches tall.

Step-by-step explanation:
I don't know what the parent function is. you did not specify that.
I guess it is f(x) = x² ?
anyway, x² is the prime example of a parabola, which simply opens upward and has the vertex (its minimum) at 0, 0.
now, g(x) is first of all multiplying this by -1.
that turns the original curve upside-down.
therefore, g(x) opens downward, and it has a maximum.
because of the mentioned upside-down action, this is a reflection across the x-axis.
the multiplication by 1/4 actually decreases the functional values compared to the basic x² curve, so the curve is below the x² curve and that means it stretches the original curve.
which of the following is a complex number?
Answer:
The complex number is B, [tex]3\sqrt{\frac{7}{5}}+\sqrt{-\frac{9}{5}}[/tex]
Step-by-step explanation:
A complex number should be written in the form [tex]a+bi[/tex], where a and b are real numbers, and i is an imaginary number.
Recall that [tex]\sqrt{-1}=i[/tex]. Since letter B has the second term [tex]\sqrt{-\frac{9}{5}}[/tex], we can say
[tex]\sqrt{-\frac{9}{5}}=\sqrt{-1\cdot\frac{9}{5}}=i\sqrt{\frac{9}{5}}[/tex]
Therefore, the number can be written as
[tex]3\sqrt{\frac{7}{5}}+i\sqrt{\frac{9}{5}}[/tex].

What are some of the factors to take into consideration when opening a savings account and what information do you
need to provide?
Answer:
The factors we might take into consideration when opening a savings account is how accessible are the banks, the types of services the bank provides, customer services, and what types of rates the bank provides.
Step-by-step explanation:
Some of the factors to take into consideration when opening a savings account are;
- Interest Rate
- Minimum Cash Balance
- Wide reach of bank
- Service Charge
Some of the factors to consider when opening a savings account are;
1) Interest Rate; Savings accounts usually pay the lowest interest rates when we compare to other investment means. This is because some pay interest rate of around 6% annually while others pay lesser. Thus, it is very important to choose the bank wisely.
2) Minimum Cash Balance; Some banks require a particular minimum balance to open a savings account. Thus, it will be wise to look for a bank that doesn't require too much initial minimum opening balance.
3) Wide reach of bank; Although many transactions can now be done online but yet there are times we have to go to the banks physically and so it will be good to go with a bank that has many branches.
4) Service Charges; Banks usually have some charges which are called service charge and they range from ATM card charges, SMS charges, transaction charges. Thus, it will be good to have an idea of these charges before opening an account.
The information required to be provided to open savings account are;
- Government issued Identification Card
- Social Security Number
- Date of birth
- Address
- Contact Information like phone number, email e.t.c
- Bank account information

What is the slope from the table?!?!
Answer:
The slope is 2.
Step-by-step explanation:
Because the "x" is increasing by 2s, you take the difference between each "y" and divide by two. This gives you four dived by 2, which equals two.
For example, taking the difference between the first "y", 7, and the second "y", 11, is 4. Because the "x" is increasing by twos, you divide by two to get the difference between one "y" and the next. Therefore, the answer is 2.
Answer:
the slope of the line is 2
Step-by-step explanation:
To find the slope of a set of points you use the equation (y 2 - y 1) over (x 2 - x 1) For this equation I will do it twice, to prove that any two sets of points will work for it, so long as x 1 and y1 and x2 and y 2 are across from each other on your table.
20, 45 will be my x 2 and y 2 points for the first equation, and 5, 15 will be my x 1 and y 1 points for the first equation. (plug in the points into the (y 2 - y 1) over (x 2 - x 1) equation). (45 - 15) over (20 - 5). 45 minus 15 equals 30, and 20 minus 5 equals 15. So now the equation is 30/15. But this is not our final slope. This can be simplified to 2/1, because 15 goes into 30 twice, so they can both be divided by 15. 2/1 is also not its final form, because 2 divided by 1 equals 2. This is the slope of your line.
1, 7 will be my x 2 and y 2 points for the second equation, and 3, 11 will be my x 1 and y 1 points for the second equation. (once again plug in the points into the (y 2 - y 1) over (x 2 - x 1) equation) We get: (7 - 11) over (1 - 3). 7 minus 11 is -4, and 1 - 3 is -2. Now we have -4/-2. If you divide -4 by -2, you get positive 2, since a negative divided by a negative becomes positive. Therefore, any 2 points work to find the slope of a group of points.

linda Put $610 in a savings account that pays 1.2% interest each year. Enrique puts $590 in a high-yield account that pays 3.9% interest each year.
Enrique would make more interest than Linda in a year.
What is interest?Interest is the amount of money made from investing a particular amount over a period of time. It is given by:
I = PRT
Where P is principal, I is interest, R is rate and T is period.
For Linda in a year:
I =610 * 1.2% * 1 year = 610 * 0.012 * 1 = $7.32

PolynomialA polynomial is mathematical equation consisting of independent variables such that, for each value of the independent variable, the function have a unique value.
How to determine whether a function is a polynomial?As for uniques values of the variable [tex]x[/tex], the value of the function [tex]f(x)[/tex] is unique so, [tex]f(x)[/tex] is a polynomial function.
The function, [tex]g(x)[/tex] is not a function as it have equal values for two different values of the variable [tex]x[/tex].
