Answer:
740 total students, 481 total girls
Step-by-step explanation:
Let x be the total number of students and y be the total number of girls
x -
You know that 35% of the students is 259 students. If you convert this into algebra, you can write : 0.35x = 259, after simplifying, you know that x = 740.
y-
You know that 35% of the students are boys, so 65% must be girls. You can say that 65% of x is y and write the equation 0.65(740)=y. After simplifying, you can see that y = 481.
I hope this helps :)

Solution :
To solve the above equation we will follow the BODMAS rule.
[tex]\small\pink\bull[/tex] BODMAS is an order of mathematic operations.[tex]\small\pink\bull[/tex] BODMAS rule is to be followed while solving expressions in mathematics.It stands for :
[tex]\begin{gathered}\quad\begin{gathered} \small \begin{array}{l} \star \: \rm B= bracket \\\star \: \rm O= order \: of \: power \: \\\star \: \rm D= division \\\star \: \rm M= multiplication \\ \star \: \rm A= addition \\ \star \: \rm S=subtraction \end{array}\end{gathered}\end{gathered}[/tex]
Solving the question by bodmas rule :
[tex]\implies\tt{\dfrac{15 - 7 + 3(6 + 2)}{{2}^{3}}}[/tex]
[tex]\implies\tt{\dfrac{15 - 7 + 3(8)}{2 \times 2 \times 2}}[/tex]
[tex]\implies\tt{\dfrac{15 - 7 + 3 \times 8}{4\times 2}}[/tex]
[tex]\implies\tt{\dfrac{15 - 7 + 24}{8}}[/tex]
[tex]\implies\tt{\dfrac{39- 7}{8}}[/tex]
[tex]\implies\tt{\dfrac{32}{8}}[/tex]
[tex]\implies\tt{\cancel{\dfrac{32}{8}}}[/tex]
[tex]\implies\tt{\underline{\underline{\red{4}}}}[/tex]
Hence, the answer is 4.

Answer:
Step-by-step explanation:
A = 180°-90°-50° = 40°
Use Law of Sines to find a:
a = b⋅sinA/sinB ≈ 20.1 units
Use Pythagorean Theorem to find c:
c = √(a² + b²) ≈ 31.3 units
:::::
sin(x) = 16/25
x = arcsin(16/25) ≈ 39.8°

the area of the rectangle shown represents a polynomial. the dimensions of this rectangle represent the ____
A. terms of the polynomial
B. square of the polynomial
C. product of the polynomial
D. factors of the polynomial
HELP ME BESTIES PLS
Answer:
D) Factors of the polynomial
Step-by-step explanation:
Example: If the polynomial 10x² represents the area of the rectangle, then
2x and 5x will be the dimensions of the rectangle. Thus they will be factors of the polynomial.
So, dimensions of the rectangle represents the factors of the polynomial.

Use prime factorization to reduce the fraction 36/180
Answer:
Step-by-step explanation:
36 = 6* 6 = 2* 3 * 2* 3 = 2*2*3*3
180 = 2 * 2 * 3 * 3 * 5 = 2 * 2 * 3*3*5
[tex]\frac{36}{180}= \frac{2*2*3*3}{2*2*3*3*5} = \frac{1}{5}[/tex]

Two lines intersect. Find the value of b and c.
bº
42°
Answer:
b=42 degrees
c= 138 degrees
Step-by-step explanation:
B and the 42 degrees shown are congruent angles so therefore both are 42 degrees
To find C: We know that combining the 42 degrees and Angle C would form a flat angle or 180 degree angle, so therefore
subtract 180 with 42 to get Angle C
180-42= 138
Answer:
b=42, c=138
Step-by-step explanation:
B has to equal 42 because b is opposite of the 42º
and since 42+2c+42 has to equal 360, we simplify the expression to get:
84+2c=360,
2c=276
c=138

The solution is
(Simplify your answer. Type an ordered pair.)
Answer:
x=4, y=3. (4, 3).
Step-by-step explanation:
y=4x-13
2x+3y=17
---------------
2x+3(4x-13)=17
2x+12x-39=17
14x-39=17
14x=17+39
14x=56
x=56/14
x=4
y=4(4)-13
y=16-13=3
