Answer:
64 is the measure of angle A.
Step-by-step explanation:
===================================================================
The triangle is an isosceles triangle, so when you use the supplementary theorem for angle BCA and 116, you get 64. And since the base pairs are equal, angle A is 64.
===================================================================
Answer:
m∠A = 64°
Step-by-step explanation:
If AB = BC , then ∠CAB ≅ ∠ACB
m∠ACB = 180° - 116° = 64° ⇒ m∠A = 64°

Explanation:
Finish the Given statement, make use of the relationships of angles and parallel lines, then finish the algebra.
__
2. m∠6 = (1/8)m∠4 . . . . Given
3. m∠6 + m∠4 = 180° . . . . 3. same-side interior angles are supplementary
4. m∠6 + 8·m∠6 = 180° . . . . 4. Substitution (from 2, above: 8·m∠6 = m∠4)
Here is the "algebra" that gets you to line 5:
4a. 9m∠6 = 180° . . . collect terms
4b. m∠6 = 20° . . . . . divide by 9
4c. m∠4 = 8·20° = 160° . . . use the same relation as in step 4
5. m∠6 = 20°, m∠4 = 160° . . . . Algebra
m∠6=1/8m∠4
m∠6+m∠4=180° S.S int. of parallel lines
m∠6+8·m∠4=180°
m∠6=20° m∠4=160°
Jordan and $35 for taking care of his neighbors lawn suppose the neighbor gave him a $15 tip which would be the total amount Jordan earned
Answers
Jordan made a total of $50 for maintaining his neighbor's yard.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
given, Jordan earned $35 for taking care of his neighbors lawn suppose the neighbor gave him a $15 tip.
Thus,
Total money Jordan earned = Salary + tip
Total money Jordan earned = 35 + 15
Total money Jordan earned = 50
therefore, the total amount Jordan earned is $50 for taking care of his neighbor's lawn.

There are 40 students in a class.
Each student walks to school or cycles to school or gets the bus to school
There are 22 girls in the class.
9 of the girls walk to school.
7 of the boys cycle to school.
6 of the 10 students who get the bus to school are boys.
Find the number of these students who walk to school.
Answers
Step-by-step explanation:
Total no. of students = 40
Total no. of girls = 22
Total no. of boys = 40 - 22 = 18
No. of girls walking to school = 9
No. of girls who cycle to school = 22 - 9
No. of boys who cycle to school = 7
No. of students who take the bus = 10
(6 boys and 4 girls)
No. of boys who walk to school = 18 - (7 + 6) = 5
Total no. of students who walk to school = 9 + 5 = 14
The number of students who walked to school was 14 students
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 ,
The equations will be ,
Let the total number of students in the class be A = 40 students
The number of girls in the class = 22 students
The number of boys in class = total number of students - number of girls
= 40 - 22
= 18 students
Now ,
The number of girls who walked to school = 9 students
The number of boys who cycled to school = 7
So , remaining boys = 18 - 7
= 11 students
The number of boys who take bus to school = 6 students
So , remaining boys = 11 - 6
= 5 students
Therefore , the remaining boys in the class walks to school = 5 students
So , the equation will be
And , the total number of students who walked to school =
number of boys in the class that walks to school + number of girls who walked to school
Total number of students who walked to school = 9 + 5
= 14 students
Hence , The number of students who walked to school was 14 students

A hot air balloon is descending at a rate of 6.75 feet per second.
What is the change in the balloon's height after 3 1/3 seconds?
Answers
The hot air balloon descends 22.498 feet after 3.333 seconds.
How much does a hot air balloon's height decreases?
The situation indicates that the height decrease is directly proportional to time. The distance is equal to the product of speed (v), in feet per second, and time (t), in seconds.
s ∝ t
s = v · t (1)
If we know that v= 6.75 ft / s and t = 3.333 ft, then the change in the height of the hot air balloon is:
s = (6.75 ft / s) · (3.333 s)
s = 22.498 ft
The hot air balloon descends 22.498 feet after 3.333 seconds.

Ali has a collection of 177 snap-together building blocks. Ali has one fourth as many red blocks as blue blocks, half as many white blocks as black blocks, an equal number of black and blue blocks, and 34 miscellaneous blocks of other colors. How many red blocks does Ali have?
Help me plz!
Answers
Answer:
The number of red blocks Ali has is 13 red balls
Step-by-step explanation:
The given parameters are;
The number of snap-together building blocks Ali has = 177
The number of red blocks Ali has = 1/4 × The number of blue blocks Ali has
The number of white blocks Ali has = 1/2 × The number of black blocks Ali has
The number of black blocks Ali has = The number of blue blocks he has
The number of miscellaneous blocks Ali has = 34
Let x represent the number of blue blocks Ali has, therefore, we have;
The number of red blocks Ali has = 1/4 × x
The number of black blocks Ali has = The number of blue blocks = x
x = 1/2 × The number of white blocks Ali has
∴ The number of white blocks Ali has = 2·x
The number of known colored blocks Ali has = 177 - 34 = 143
Therefore, we have;
x + 1/4·x + x + 1/2·x = 143
11/4·x = 143
x = 143 × 4/11 = 52
Therefore, the number of blue blocks Ali has = x = 52 blue balls
The number of red blocks Ali has = 1/4 × The number of blue blocks Ali has = 1/4 × 52 = 13
The number of red blocks Ali has = 13 red balls.

Rachel worked 2.5 hours on Monday, 3.5 hours on Tuesday, 2 hours on Thursday, and 5 hours on Saturday. She is paid $10.66 per hour. How much money did Rachel earn that week?
Answers
Answer:
$138.58
Step-by-step explanation:
You would first set up an equation. You want to know how much money Rachel earned that week, so let's refer to that by using variable t for total money earned this week.
Next, we also know that Rachel is paid 10.66 per hour, so we'll be multiplying it by the number of hours she worked this week. This allows us to set our equation up as follows:
10.66(2.5+3.5+2+5) = t
You would now add like terms.
10.66(13) = t
You would now multiply 10.66 and 13(total number of hours worked this week).
This would get us 138.58, or the total numnber of money Rachel earned this week.

Help please by slope and y- intercept
Answers
Answer:
Slope = -3/4Y - intercept = -3Step-by-step explanation:
y = mx + b
mx = slope
b = intercept
1. Simplify the equation
4y = -3x - 12
2. Divide both sides by 4
y = -3/4 x - 3
3. Make a graph
First start at the y-intercept, (0, -3)*
Then, use the pattern -3/4
It is called rise over run.
But, when the slope is negative you have to go down instead of up. So you have to go down 3 and 4 to the right.
Continue that pattern until you get your result.
But when you have to go to the upper part of the graph go up 3 and over 4 to the left.
Continue this pattern.
This also applies to other graphs.
* = remember a y-intercept always has a 0 as the x - coordinate.
