Answer:
[tex]40\frac{5}{8}mm^2[/tex]
Step-by-step explanation:
To find the area of a triangle, one must use the formula,
[tex]\frac{base*height}{2}[/tex]
It is given that
- base = [tex]9\frac{3}{4}[/tex]
-height = [tex]8\frac{1}{3}[/tex]
Substitute in the values and solve;
[tex]\frac{9\frac{3}{4}*8\frac{1}{3}}{2}[/tex]
In order to multiply the two fractions, one must convert them from mixed number form to improper fraction form. This can be done by multiplying the denominator (the number under the fraction bar), by the "number" part of the mixed number, and then adding the result to the numerator (the number over the fraction bar;
- base = [tex]9\frac{3}{4}=\frac{(9*4)+3}{4}=\frac{36+3}{4}=\frac{39}{4}[/tex]
- height = [tex]8\frac{1}{3}=\frac{(8*3)+1}{3}=\frac{24+1}{3}=\frac{25}{3}[/tex]
Substitute,
[tex]\frac{\frac{39}{4}*\frac{25}{3}}{2}[/tex]
Cross simplify,
[tex]\frac{\frac{325}{4}}{2}[/tex]
Further simplify,
[tex]\frac{325}{4}*\frac{1}{2}\\\\= \frac{325}{8}[/tex]
Convert back to a mixed number divide the numerator by the denominator, write the whole-number result as the number outside of the fraction, and the remainder as the numerator of the fraction,

Jason is a skilled rapper. He has already rapped a 40-word intro to a song and continues to rap 5 words per second.
Write an inequality to determine how many more seconds tt he will rap to complete the song if the total song, including the intro, is at least 500 words.
Answer:
5[tex]t[/tex] + 40 ≤ 500
Step-by-step explanation:
Jason can rap 5 words per second
5t
He can already rap 40 words into the song
40
There are 500 words to the whole song
500
5[tex]t[/tex] + 40 ≤ 500
The inequality to determine how many more seconds t he will rap to complete the song if the total song, 5t+ 40 ≥500.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
Jason can rap 5 words per second
let 't' be the time Jason rap then number of words he rap after t seconds 5t.
and, He can already rap 40 words into the song
Also, the whole sing contains 500 words.
Then, the inequality is
5t+ 40 ≥500.

Answer:
x≈11.8
Step-by-step explanation:
Since this is a right triangle, we can use cosine to find the length of CD.
First, set up an equation, then solve:
cos(49°)=18/x
x=18/cos(49°)
x≈ 11.80906252
rounded to the nearest tenth of a foot:
x≈11.8
Answer:
Step-by-step explanation:
Remark
The adjacent side is one of the two sides making up the acute angle in a right triangle. The second side is the Hypotenuse.
Givens
Cos(C) = side Adjacent / Hypotenuse
Cos(49) = 0.6561
Side Adjacent = 18
Solution
Cos(C) = side adjacent / Hypotenuse Multiply both sides by the hypotenuse
Hypotenuse * Cos(C) = Side Adjacent Divide by Cos(C)
Hypotenuse = Side Adjacent / Cos(C)
Hypotenuse = 18 / Cos(C)
Hypotenuse = 18 / 0.6561
Hypotenuse = 27.437

SCHOOL ELECTIONS Henrietta conducted a random survey of 60 students and found that 36 are planning to vote for her as class
president. If there are 460 students in Henrietta's class, predict the total number of students who will vote for her as class president.
Answer:
276 students
Step-by-step explanation:
36/60=0.6
Therefore, 60% of students in the random survey are planning to vote for her. Using that 60%, we can predict how many students in all will vote for her.
460(0.6)=276
That means 276 students will vote for her.

To amend a country's constitution, 3/4
of the 46 states in that country must approve the amendment. If 35 states approve an amendment, will the constitution be amended?
Answer:
to answer the question we need to know if 35 out of 50 states is equal or greater than 3/4 if that is the case, the Constitution will be ammended, and that is represented like this:
35/50 >= 3/4
that inequality is saying that 35 states out of 50 is equal or greater than 3/4, lets simplify and modify the fractions to compare easily:
35/50 >= 3/4
7/10 >= 3/4
now we need to find the least common multiplier of 10 and 4 to take the fractions to a common denominator and compare easy. Lets multiply numerator and denominator for a correct number to get the fractions to denominator common 20, the lcm:
7/10 >= 3/4
(2/2)(7/10) >= (5/5)(3/4)
2*7/2*10 >= 5*3/5*4
14/20 >= 15/20
we can see that the inequality does not hold, so,
35/50 >= 3/4
does not hold either, therefore the Constitution cannot be ammended

Perry deposits $175 into a simple interest account. The interest rate for the account is 4.25%. What would his final balance be in his account after 3 years?
Answer:
$197.31
Step-by-step explanation:
Given data
Principal= $175
Rate= 4.25%
TIme= 3 years
The expression for the simple interest is given as
A=P(1+rt)
substitute
A= 175(1+0.0425*3)
A= 175(1+0.1275)
A= 175(1.1275)
A= $197.31

Answer:
A & B
Step-by-step explanation:
cos(theta)tan(theta) can be expressed as;
cos(theta)tan(theta) = cos(theta) × (sin(theta))/cos(theta).
cos(theta) cancels out to give; sin(theta)
Thus is equivalent to option A

Find the Cartesian equation of the curve with parametric equations x = 2 sec(t) and y = 3 tan(t) for t ∈ π/2 , 3π/2, and describe the curve.
Answer:
4y^2 - 9x^2 = -36
Step-by-step explanation:
x = 2 sec t
y = 3 tan t
x^2 = 4 sec^2 t
y^2 = 9 tan^2 t
Now sec^2t = 1 + tan^2 t so we have:
4(1 + tan^2 t) + 9 tan^2 t = x^2 + y^2
4 + 13 tan^2 t = x^2 + y^2
13 tan^2 t = x^2 + y^2/ - 4
tan^2 t = x^2/13 + y^2/13 - 4/13
But , from the second equation tan t = y/3 so tan^2 t = y^2/9, so:
y^2/9 = x^2/13 + y^2/13 - 4/13
LCM of 9 and 13 is 117 so multiply thru by 117:
13y^2 = 9y^2 + 9x^2- 36
4y^2 - 9x^2 = -36

i need help finding the area of these two
Answer:
50 cm² and 56 cm²
Step-by-step explanation:
The area (A) is calculated as
A = [tex]\frac{1}{2}[/tex] × d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )
(2)
A = [tex]\frac{1}{2}[/tex] × (8 + 2) × (5 + 5)
= 0.5 × 10 × 10
= 5 × 10
= 50 cm²
(3)
A = [tex]\frac{1}{2}[/tex] × (12 + 2) × (4 + 4)
= 0.5 × 14 × 8
= 7 × 8
= 56 cm²
12. In a certain cafe, all the sandwiches and drinks are priced the
same. A customer ordered three sandwiches and two drinks for
$14.70. Another customer bought two sandwiches and four drinks
for $13.80. Find the cost of one sandwich and the cost of one drink.
The cost of one sandwich is $3.90
The cost of one deknk is $1.50
hopefully this is correct
The system of equations are
The cost of one sandwich x = $ 3.90
The cost of one drink y = $ 1.50
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of one sandwich be x
Let the cost of one drink be y
Now , the equation will be
A customer ordered three sandwiches and two drinks for $14.70
So , 3x + 2y = 14.70 be equation (1)
And , Another customer bought two sandwiches and four drinks for $13.80
So , 2x + 4y = 13.80 be equation (2)
On simplifying the equations , we get
Multiply equation (1) by 2 , we get
6x + 8y = 29.4 be equation (3)
Subtracting equation (2) from equation (3) , we get
4x = 15.6
Divide by 4 on both sides of the equation , we get
x = $ 3.90
So , the cost of one sandwich is $ 3.90
And ,
Substituting the value of x in equation (1) , we get
3x + 2y = 14.70
3 ( 3.90 ) + 2y = 14.70
11.70 + 2y = 14.70
Subtracting 11.70 on both sides of the equation , we get
2y = 3
Divide by 2 on both sides of the equation , we get
y = $ 1.50
So , the cost of one drink is $ 1.50
Hence , the cost of one sandwich and one drink is $ 3.90 and $ 1.50 respectively
