Answer:
a) Write a let statement below to define your variable(s):
Let the number of fishes Ms. Montesinos has be represented by = f
b) Set up an equation using the variable you defined in (a):
The equation is :
3f - 2 = 13
c) Solve your equation & Check. How many fish does Ms. Montesinos have?
Ms. Montesinos has 5 fishes
Step-by-step explanation:
Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has. How many fish does Ms. Montesinos have in her tank?
a) Write a let statement below to define your variable(s):
Let the number of fishes Ms. Montesinos has be represented by = f
b) Set up an equation using the variable you defined in (a):
We are told in the question:
Ms. Cruz has a tank with 11 fish. After buying two more, she has 2 less than triple the amount of fish Ms. Montesinos has.
Therefore,
3× f - 2 = 11 + 2
The equation is :
3f - 2 = 13
c) Solve your equation & Check. How many fish does Ms. Montesinos have?
Solving the above equation:
3f - 2 = 13
3f = 13 + 2
3f = 15
Divide both sides by 3
3f/3 = 15/3
f = 5
Hence, Ms. Montesinos has 5 fishes
Two vectors of lengths 4 and 6 have a dot product equal to 24. Which is true about the vectors?
They form an acute angle.
They form an obtuse angle.
They point in the same direction.
They point in opposite directions.
Answer:
no its not its b The angle between the vectors is obtuse.
Step-by-step explanation:
oh for the other one
he is right for that one but im right on the other thing for it like it
Both vectors point in the same direction.
Dot products of vector:The dot product of two vectors is given as,
[tex]a\cdot b=ab*cos\theta[/tex]
Where [tex]\theta[/tex] is angle between two vectors.
Given that, [tex]a\cdot b=24,a=4,b=6[/tex]
Substitute values in above relation.
[tex]24=4*6*cos\theta\\\\cos\theta=24/24=1\\\\\theta=cos^{-1}1=0[/tex]
Thus, both vectors point in the same direction.

Express as a trinomial. (3x – 10) (3x - 1)
Answer:
9x² - 33x + 10
Step-by-step explanation:
Given
(3x - 10)(3x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(3x - 1) - 10(3x - 1) ← distribute both parenthesis

Which statements are true about trapezoid ABCD and its translated image, A'B'C'D'? Select two options.
Answer:
A,D
Step-by-step explanation:
The requried, expression for the translation of trapezoid ABCD to A'B'C'D' is (x, y) ⇒ (x - 3, y +1). Options A and D both are correct.
What is the transformation of geometry over the coordinate plane?Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.
Here,
Consider trapezoid ABCD,
As we can see the trapezoid is translated 3 units to the left and one unit up,
So the expression of the given translation is given as,
(x, y) ⇒ (x - 3, y +1)
To for the trapezoid A'B'C'D'.
Thus, the requried, expression for the translation of trapezoid ABCD to A'B'C'D' is (x, y) ⇒ (x - 3, y +1). Options A and D both are correct.

Jose earns $3680 per month, of which 22% is taken out for federal and state income taxes and other required deductions. Last month he spent $775 for rent and 86.12 on clothing. What percent of his take-home pay did he spend on rent and clothing combined?
Answer: 30%
Step-by-step explanation:
Firstly, we find 22% of $3680. This will be:
= 22% × $3680
= 0.22 × $3680
= $809.60
Therefore, his take home pay will be:
= $3680 - $809.60
= $2870.40
We are further told that last month he spent $775 for rent and 86.12 on clothing. The amount combined will be:
= $775 + $86.12
= $861.12
The percent of his take-home pay did he spend on rent and clothing combined will be:
= 861.12 / 2870. 40 × 100
= 30%
Answer:
30%Step-by-step explanation:
Step one:
monthly earnings= $3680
22% of the earnings is
=22/100*3680
=0.22*3680
=$809.6
Jose's take home will be
3680-809.6
=$2870.4
Step two:
Required
percentage spent on rent and clothing
but the total cost of rent and clothing is
=775+86.12
=$861.12
percentage of rent and cloth is
=(861.12/2870.4)*100
=0.3*100
=30%
The percentage is 30% of the take home

The addition is one of the four fundamental mathematical operations. The two of the given numbers are 36 and 28.
What is Addition?The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.
Let the sum of two numbers be represented by a and b.
Given that the sum of the two numbers is 64. Therefore, we can write,
a + b = 64
Also, it is given that the difference between the two numbers is 8, therefore, we can write,
a - b = 8
Adding the two of the equation formed together, then,
a + b + a - b = 64 + 8
2a = 72
a = 72/2
a = 36
Substitute the value of a in any one of the two equations,
a + b = 64
36 + b= 64
b = 64 - 36
b = 28
Hence, the two of the given numbers are 36 and 28.

Step-by-step explanation:
f(4) is another notation for x = 4
so we just plug-in 4 for x
f(4) = -4((4)+3)
f(4) = -4(7)
f(4) = -28
The value of f(4) for the function is -28
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given a function as f(x) = - 4(x + 3)
f(4) is another notation for x = 4
Therefore we just plug-in 4 for x
f(x) = - 4(x + 3)
f(4) = -4((4)+3)

simplify by dividing [ -3/-8] divided by 5/9 (5 points)
A. -15/-72
B. 15/72
C. -27/-40
D. 27/40
Answer: D
Step-by-step explanation:
(3/8) / (5/9) is the same as multiplying (3/8) by (9/5) which is 27/40. I'm not sure if there's an error between C and D because those are both the same answer since dividing a negative number by a negative number gives you a positive number.
I think C was supposed to be -27/40 so D is the correct answer since it's positive.

What is 1 1/3 minus 5/6
Answer:
1/2
Step-by-step explanation:
First, convert 1 1/3 to improper fraction:
1 1/3 = 4/3
Second, make denominator the same by multiplying 4/3 by 2/2:
4/3 * 2/2 = 8/6
Third, subtract:
8/6 - 5/6 = 3/6
Fourth, simplify:
3/6 = 1/2
The correct answer for the difference between [tex]1\dfrac{1}{3}[/tex] and [tex]\dfrac{5}{6}[/tex] is [tex]\dfrac{1}{2}[/tex] .
Given expression:
[tex]1\dfrac{1}{3} - \dfrac{5}{6}[/tex]
convert [tex]1\dfrac{1}{3}[/tex] to an improper fraction:
[tex]1\dfrac{1}{3} = \dfrac{3*1 + 1}{3}[/tex]
= [tex]\dfrac{4}{3}[/tex]
Now, the expression becomes:
[tex]\dfrac{4}{3} - \dfrac{5}{6}[/tex]
To subtract these fractions,
The common denominator is 6.
Rewrite the fractions with the common denominator:
[tex]\dfrac{4}{3}*\dfrac{2}{2}[/tex]
= [tex]\dfrac{8}{6}[/tex]
The expression becomes:
[tex]\dfrac{8}{6} - \dfrac{5}{6}[/tex]
Subtract, the numerators while keeping the common denominator:
= [tex]\dfrac{8-5}{6}[/tex]
= [tex]\dfrac{3}{6}[/tex]
Divide numerator and denominator by greatest common factor (which is 3):
3 ÷ 3 = 1
6 ÷ 3 = 2

Answer:
1.728 × 106 pounds of vegetation
Step-by-step explanation:
From the question, each elephant eats 2.16 × 105 pounds of vegetation per year.
Since there are eight elephants, it will cost a total of 8× 2.16 × 105 pounds of vegetation per year = 1.728 × 106 pounds of vegetation
