Answer:
The answer is 6î + 9j – 15k
Step-by-step explanation:
Given;A = 2î + 3j – 5kTo Find;Value of 3ASo,
A = 2î + 3j – 5k
Multiply The value of A with 3 we get,
3A = 3(2î + 3j – 5k)
3A = 6î + 9j – 15k
Thus, The value of 3A is 6î + 9j – 15k

The price for 3 protein bars $3.75, and the price of 3 fruit cups is $1.50. Write the equation
that represents the relationship between the number of protein bars, x, and fruit cups, y,
that you can buy with $15.50.
How many fruit cups can you buy with 4 protein bars?
Answer:
7 fruit cups
Step-by-step explanation:
$3.75/3x + $1.50y = $15.50
So, if you have 4 protein bars, the equation would read:
1.25x + 1.5y = 15.5
1.25(4) + 1.5y = 15.5
5 + 1.5y = 15.5
1.5y = 10.5
y = 7

Use the five rules to determine whether the following are valid from the Boolean standpoint, valid from the Aristotelian standpoint, or invalid. For those that are invalid from either the Boolean or Aristotelian standpoint, name the fallacy or fallacies committed. Check your answer by constructing a Venn diagram for each.
i. No individuals sensitive to the difference between right and wrong are people who measure talent and succss in terms of wealth.
ii. All corporate takeover experts are people who measure talent and success in terms of wealth.
iii. Therefore, no corporate takeover experts are individuals sensitive to the difference between right and wrong.
The statements presented would be valid from both the Aristotelian and the Boolean standpoint.
What are the principles that make statements valid or invalid?Some principles to test is statements are valid or invalid are:
Universal prepositions are valid if they refer to existing elements (Aristotelian standpoint).Prepositions are valid if the premises and conclusion are valid even if these do not refer to existing elements (Boolean standpoint).Based on this, the statements presented would be valid from both the Aristotelian standpoint and the Boolean standpoint because the premises (I and II) are logically connected, and they refer to existing elements.

Answer:
the first option is correct
In a function, y varies directly with x and the constant variation is 2, then the function is y=2x. Therefore, option D is the correct answer.
What is direct variation?Mathematical relationship between two variables which can be expressed by an equation in which one variable is equal to a constant times the other.
Given that, in a function, y varies directly with x and the constant variation is 2.
y∝x
y=kx, where k is constant variation.
Here, k=2
Then, y=2x
When x=1, 2, 3, 4 and 5.
We get, y 2, 4, 6, 8 and 10
Therefore, option D is the correct answer.

Identify the terms and the like terms in this expression. 7 + a – 2 + 3a + b2 Which statements are true? Check all that apply.
- The expression contains seven terms.
- The terms in the expression are 7, a, 2, 3a, b2.
- Constants are like terms.
- 2 and b2 are like terms because they both contain the number 2.
- a and 3a are like terms.
- a, 3a, and b2 contain variables, so they are like terms
Step-by-step explanation:
Terms can be a single number or variable, or a coefficient.
The expression contains seven terms, incorrect. Doesn't include coefficients.
The terms in the expression are [tex]7[/tex], [tex]a[/tex], [tex]2[/tex], [tex]3a[/tex], [tex]b^2[/tex]. Correct. Includes coefficients.
Constants are like terms, correct. (7, 2)
2 and [tex]b^2[/tex] are like terms because they both contain the number 2, incorrect. [tex]b^2[/tex] can only combine with a coefficient with the exact same terms. ([tex]b^2[/tex])
a and 3a are like terms, correct. Both are like terms since both have the variable of a.
a, 3a, and [tex]b^2[/tex] contain variables, so they are like terms. Incorrect. As said before, [tex]b^2[/tex] can't combine with 3a and a. (4a)

m = [?]

Give your answer in simplest form.
Enter
Answer:
m = 4√6
Step-by-step explanation:
Using the "geometric mean" relations applicable to this triangle, the value of m is the geometric mean of the hypotenuse segments it touches:
m = √((8)(8+4)) = √96
m = 4√6
__
Additional comment
Similarly, n = √(4×8) = 4√2.
These relations come from the similarity of the triangles. For m, the proportion is ...
long side/hypotenuse = 8/m = m/12
96 = m² ⇒ m = 4√6

Answer: A
Step-by-step explanation: πr2 h = 1100 cm³
Here r = 5
(22/7) ⋅ (5)2 ⋅ h = 1100
h = 2/7
Curved surface area of cylinder = 2 πr h
= 2 ⋅ (22/7) ⋅ 5 ⋅ (2/7)
= 440 cm²
So, the curved surface area of cylinder is 440 cm²

Milo is making 1 1/2 batches of muffins for a bake sell. If each batch of muffins calls for 1 3/4,how many cups of flour will he need ?
Answer:
2 5/8
Step-by-step explanation:
Because she has one whole batch of cookies that will require 1 3/4 of flour. Since the remainder is a 1/2 batch, you would have to half the 1 3/4. Halfing 1 3/4 is 7/8. You add 1 3/4 + 7/8 and you get 2 5/8.
Can the sides of a triangle have lengths 7, 12, and 18?
Answer:

Step-by-step explanation:
By the Triangle Inequality Theorem, if a supposed triangle has sides [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] where [tex]c[/tex] is the longest side, then [tex]a+b\geq c[/tex].
Here, [tex]7+12\geq18[/tex], so the given sides of the triangle can have these lengths

Step-by-step explanation:
Subtract 13 dinosaurs from the 76 original dinosaurs
76-13 = 63
Now divide them into 9 groups
63/9 = 7
There are 7 dinosaurs in each group
