Answer:
a=5.81
Step-by-step explanation:
We want to solve for the value of a in the expression:
[TeX]\frac{sin 45}{a}=\frac{sin 77}{8}[/TeX]
Cross Multiply
8 X sin 45=a X sin 77
Divide both sides by sin 77° to obtain a.
[TeX]a=\frac{8 X sin 45}{sin 77}[/TeX]
a=5.81

When you solve a linear equation how do you recognize if the equation has 1 solution no
solution, or infinite solution?
Answer:
If you solve a linear equation you have two different lines.
Now with that being said the solutions are as follows;
One Solution: The slopes are different
No solution: The slopes are the same and the y intercepts are different
Infinite Solutions: The slopes are the same and the y intercepts are different
Solve using substitution. x + 2y = 4 and –4x − 7y = –9
Step-by-step explanation:
Given
x + 2y = 4
x = 4 - 2y.......... equation 1
-4x -7y = - 9.......equation 2
Putting equation 1 in equation 2
- 4 ( 4 - 2y) - 7y = - 9
-16 + 8y - 7y = -9
y = - 9 + 16
y = 7
Now
x = 4 - 2* 7 = 8 - 7 = 1
hope this helps.
Answer:
X=-10 y=7
Step-by-step explanation:
1) in first equation subtract 2y on both sides
X=4-2y
Substitute as "x" in the second equation:
-4(4-2y)-7y=-9
-16+8y-7y=-9
-16+y=-9
Y=7
Substitute y as 7 to get x)
X=4-2(7)
X=4-14
X=-10

Find the area of the circle. Round to the nearest tenth.
Answer:
28.27
Step-by-step explanation:
Area= pi x radius squared
Radius is 1/2 the diameter which in this case is 6 ft
So, pi x 3 squared (9)
= 28.27
Answer:
28.3
Step-by-step explanation:
Hello!
To find the area of a circle we use πr².
In this case, all we have to do is divide 6 by 2 and square that.
6 ÷ 2 = 3. 3² = 9.
9 × π = 28.2743....
Rounding to the nearest tenth:
28.3
Thus, the area of the circle is [tex]\boxed{28.3}[/tex].

If three-quarters of a gallon of ice cream was shared equally among the 5 people, what fraction of a whole gallon did each person receive?
Answer:
3/20
Step-by-step explanation:
If you divide 3/4 by 5 you get 3/20
Answer:
3/20
Step-by-step explanation:
We have 3/4 of a gallon, and we want to divide it equally among 5 people. So, we can divide 3/4 by 5
3/4 /5
Divide by 5, or multiply by the reciprocal of 5. To find the reciprocal, flip the numerator and denominator
Reciprocal: 5/1 ---flip---> 1/5
3/4 * 1/5
Multiply across the numerator and denominator
3/20
Each person gets 3/20 of a gallon

3. Which of the following is equivalent to 3(y – 1 + 2y)? A. 3y – 9 B. 6y – 3 C. 9y – 3 D. 3y – 3
Final answer:
To solve the equation 3(y - 1 + 2y), distribute the 3 to each term inside the parentheses, combine like terms, resulting in 9y - 3.
Explanation:
To solve the equation 3(y - 1 + 2y), we need to distribute the 3 to each term inside the parentheses:
3 × y = 3y
3 × -1 = -3
3 × 2y = 6y
So the equation becomes 3y - 3 + 6y. Combining like terms, we get 9y - 3. Therefore, the correct equivalent expression is 9y - 3 (Option C).
Final answer:
The correct answer to the given expression 3(y – 1 + 2y) is 9y - 3, after distributing the 3 and combining like terms.
Explanation:
The given mathematical expression is 3(y – 1 + 2y). To simplify it, we should first distribute the 3 across the parentheses and then combine like terms. Here's how:
Step 1: Distribute the 3: 3 × y + 3 × (-1) + 3 × 2y = 3y - 3 + 6yStep 2: Combine like terms (3y and 6y): 3y + 6y = 9y, and you still have the -3 from the previous step.Step 3: The final simplified expression is 9y - 3.Thus, the correct answer is C. 9y – 3.

What is the remainder in the synthetic division problem below? 1/1 2 -3 3
Answer:
3
Step-by-step explanation:
I'm assuming you want to do the following synthetic division:
1 / 1 2 -3 3
1 3 0
--------------------------------
1 3 0 3 The remainder is 3.
The remainder is -2
The remainder in synthetic division is the constant term of the quotient. To find the remainder of the synthetic division problem above, we can use the following steps:
Arrange the coefficients of the dividend and divisor in descending order of degree.
Set up the synthetic division table as follows:
2 -3 3 |1
---------------
1
Bring down the first coefficient of the dividend.
Multiply the coefficient we just brought down by the divisor and place the product in the next column.
Subtract the product from the corresponding coefficient of the dividend and place the difference in the next column.
Repeat steps 4 and 5 until we reach the last column.
The remainder is the last number in the bottom row of the synthetic division table.
Following these steps, we get the following synthetic division table:
2 -3 3 |1
---------------
1 2 -1
-2 -4 2
--------
-2
Therefore, the remainder is -2

Answer:
3. 83%, or A
Step-by-step explanation:
First you have to create the variables.
If you need to find the probablility of two items, then you first add them.
11+14 = 25.
Now, you add all the numbers.

Enter the value of b when the expression 8/9x+b is equivalent to 1/9 (8x+5)
Answer:
b = 5 / 9
Step-by-step explanation:
8/9x + b = 1/9(8x + 5)
Make b the subject of formula.
b = 1/9 (8x + 5) - 8/9x
Multiply through by 9
9b = 9 * 1/9 ( 8x + 5) - 9 * 8/9x
9b = 8x + 5 - 8x
9b = 5
b = 5 / 9
The value of b = 5 / 9

three bags of chips costs m cents. At this rate, what is the cost, in cents, of one bag of chips?
Answer: m/3 cents
Step-by-step explanation:
Hi, to answer this question we have to divide the total cost of the chips (m) by the number of bags of chips (3).
Mathematically speaking:
Cost of one bag chip: m/3 cents
Since the total cost is represented by a variable, the individual cost is an expression.
If we replace the value of m by a number we will obtain the result as a number.

Find the degree of the monomial -4/9
Answer:
Step-by-step explanation: the degree is 0
Final answer:
The degree of the monomial -4/9 is 0 since it contains no variables and can be considered to have variables with an exponent of 0.
Explanation:
The degree of a monomial is the sum of the exponents of all its variables. In the case of the monomial -4/9, there are no variables present, which means that the degree is 0. This is because the monomial can be considered to have variables raised to the power of 0, and any number (except zero) raised to the power of 0 is 1, which does not affect the value of the coefficient (-4/9).
