Answer:
1)m<DCH =89
2)m<BCD=103
Step-by-step explanation:
1) We have that:
m<EFB=91 degree.
We want to find m<DCH.
By same side interior angle property:
m<DCH +m<EFB=180
m<DCH +91=180
m<DCH=180-91
m<DCH =89
2) Given that: m<HFG=103, we seek to find m<BCD.
By the alternate exterior angle property:
m<HFG=m<BCD
Therefore
m<BCD=103
What is the solution to the system that is created by the equation y = negative x + 6 and the graph shown below? On a coordinate plane, a line goes through (0, 0) and (4, 2). (–8, –4) (–4, –2) (4, 2) (6, 3)
Answer:
The solution point is (4,2).
Step-by-step explanation:
Equation of straight line passing through the points (0,0) and (4,2) is given by
[tex]\frac{y - 2}{2 - 0} = \frac{x - 4}{4 - 0}[/tex]
⇒ 2y = x ............ (1)
And the other straight line is y = - x + 6 .............. (2)
Now, solving equations (1) and (2) we get, y = - 2y + 6
⇒ 3y = 6
⇒ y = 2
And from equation (1) we get, x = 2y = 4
Therefore, the solution point is (4,2). (Answer)

B. For roses you could sell 84 bunches of 14 roses. For tulips, you could sell 70 bunches of 18 tulips, and for gerberas, you could sell 75 bunches of 18 gerberas.
C. well 8 dollars times 84 is $672. 11 times 70 equals $770, and 9 times 75 is $675. in total $2,117.
D. i - 1176 well to start we add up all the digits to see if its sum is divisible by 9. 1+1+7+6=15. 15 is not a multiple of 9 so its not divisible.
ii. 1260 well to see if 1260 is divisible by 8 is by taking the last 3 digits of the number and dividing it by 8. 260 divided by 8 equals 32.5. since 32.5 is a decimal and 8 can't go into 260 evenly 1260 is not divisible by 8.

I need to know whether or not 15, 13, 11, 9, ... is an arithmetic sequence
Answer: Yes
Step-by-step explanation: An arithmetic sequence is a sequence that has a common difference. The common difference is the number that is repeatedly added or subtracted to reach the next term in the sequence.
In this sequence, notice that we start with 15. Then, we subtract 2 to reach our next term which is 13. Next, we subtract 2 to get to our next term which is 11. In the same way, we subtract 2 from 11 to reach our next term, 9.
The dot dot dots just mean that this sequence goes on forever so to answer your question, this is indeed an arithmetic sequence.
Edward had 45 water bottles. If he drank 1/9 of water bottles, how many did he drank?

Rewrite the equation y=2|x−3|+5 as two linear functions f and g with restricted domains.
Please help
Answer:
f(x) = 2+5
g(x) = 2(-(x−3))+5
Step-by-step explanation:
If you remember, an absolute value can have two different answer, a positive and negative answer because the absolute value symbol makes all values in it positive. Example: |-2|=2 and |2|=2
So if y = 2|x−3|+5
then the two possibilities are
y = 2(x−3)+5 and
y = 2(-)+5
Set one of them equal to f(x) and the other one to g(x)
f(x) = 2(x−3)+5
g(x) = 2(-(x−3))+5
You can also write it as a piecewise function.

Heather is making a blanket for her baby and is going to put a ribbon border around it. The blanket will be 3 feet by 5 feet. The fabric for the blanket cost $1.25 per square yard and the ribbon costs $.50 per foot. What is the approximate total cost for the blanket? A) $1.75 B) $10.08 C) $20.84 D) $26.75 E) $32.48
Answer:
The approximate total cost for the blanket is $10.08 ⇒ B
Step-by-step explanation:
The formula of the area of a rectangle is A = L × W
The formula of the perimeter of a rectangle is P = 2(L + W)
where:
L is the length of the rectangleW is the width of the rectangle∵ The baby blanket shaped a rectangle
∵ The dimensions of the blanket are 3 feet and 5 feet
- Find the area of the blanket
∵ A = 3 × 5 = 15 feet²
- Change feet to yard because the cost is by square yard
∵ 1 foot = [tex]\frac{1}{3}[/tex] yard
∴ 1 foot² = [tex](\frac{1}{3})^{2}=\frac{1}{9}[/tex] yard²
∴ 15 feet² = 15 × [tex](\frac{1}{9})[/tex] = [tex]\frac{5}{3}[/tex] yards²
∴ The area of the blanket is [tex]\frac{5}{3}[/tex] yards²
∵ The fabric cost of the blanket is $1.25 per square yard
∴ The fabric cost = [tex]\frac{5}{3}[/tex] × 1.25
∴ The fabric cost = 2.08333 dollars
∵ Heather is going to put a ribbon border around it
- The length of the ribbon is equal to the perimeter of the blanket
∵ P = 2(3 + 5) = 16 feet
∴ The length of the ribbon is 16 feet
∵ The cost of the ribbon is $0.5 per foot
∴ The cost of the ribbon = 16 × 0.5
∴ The cost of the ribbon = 8 dollars
Now add the fabric cost to the ribbon cost to find the total cost of the blanket
∵ The total cost = 2.08333 + 8
∴ The total cost = 10.08333
- Round it to the nearest cent
∴ The total cost = 10.08 dollars
The approximate total cost for the blanket is $10.08

OD. The student should have used

Answer:
B. On Pearson (-1/4) D on Egdenuity(-1/4)
The student erred in calculating the slope for the line perpendicular to the given line. They should have used -1/4 instead of 2. The correct equation is y - 5 = -1/4 * (x + 8).
Explanation:The error the student made lies in calculating the slope of the line that is perpendicular to given line y = 4x + 2. The slope of this line is 4, therefore the slope of the line perpendicular to it should be the negative reciprocal of 4, which is -1/4, not 2 as the student assumed. We also use the point-slope form of the line which is y - y1 = m(x - x1). Substituting m as -1/4 (the slope of perpendicular line) and the point (-8,5) into the equation, we should get y - 5 = -1/4 * (x + 8).

Are the polygons similar? If they are, choose the correct similarity statement and scale factor. Not drawn to scale.
Option B: [tex]$\Delta R S T \sim \Delta UV W ; \frac{5}{6}$[/tex]
Explanation:
The polygons are similar because in [tex]$\Delta R S T$[/tex], the measure of ∠R=32°
Also, in [tex]$\Delta U V W$[/tex], the measure of ∠U=32°
Now, we shall find the scale factor,
Since, [tex]$\Delta R S T \sim \Delta U V W$[/tex], then the sides are proportional which is given by,
[tex]\frac{RS}{UV}[/tex]
Substituting the values of RS and UV from the figure, we get,
[tex]\frac{10}{12}[/tex]
Simplifying, we have,
[tex]$\frac{5}{6}$[/tex]
Thus, the scale factor is [tex]$\frac{5}{6}$[/tex]
Hence, Option B is the correct answer.

What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Let consider an example.
Consider the slope-intercept form of equations: y = -6x+8 and y=-3x-4
Since the slopes are different, the lines must intersect.
Because the lines intersect at a point, there is one solution to the system of equations the lines represent.

What is one whole and three fourths plus five sixths plus one whole and one fourth
Answer:
First of all cant give u the anssswer i am srry but i can give u a hint u need to find eqivelent fractions for the denominators then u can add them
Step-by-step explanation:
Answer: The answer is Three whole and five sixths (3 5/6)
Step-by-step explanation: One whole and three fourths can be expressed as 1 3/4, and this is added to five sixths, that is, 5/6. therefore these can be expressed as
[1 3/4 + 5/6}
The other part of the questions says one whole and one fourth which can be expressed as 1 1/4.
The entire question can now be written out as
[1 3/4 + 5/6] + [1 1/4]
We would start by solving for the left hand side of the expression
1 3/4 + 5/6
= 7/4 +5/6
By using a common denominator which is 12 (the LCM), the expression now becomes,
[21 + 10]/12
= 31/12
We can now add this to the right hand side of the expression. Thus,
[31/12] + 1 1/4
=31/12 + 5/4
By using a common denominator which is also 12, the expression now becomes,
[31 + 15]/12
= 46/12, By simplifying further we arrive at,
23/6.
Written as a proper fraction, this becomes
3 5/6 (Three whole and five sixths)
A rectangle flag had a width of 3 2\3 feet and area of 8 3/4 square feet . Which expression could be used to calculate the length , in feet , of the rectangle
Pretty sure it's 8 3/4 ÷ 3 2/3.
Why?
So say you want to find the length of a rectangle who's area is 6, and the width is 2. You can divide the area by the width to find the length. 6/2 = 3.
Check: 2 * 3 = 6.
Back to the original question: 8 3/4 ÷ 3 2/3.
Improper fractions: 35/4 ÷ 11/3.
Switch division to multiplication and reciprocal: 35/4 * 3/11.
35/4 * 3/11 = 105/44.
Check:
105/44 * 11/3 = 1155/132 = 35/4 = 8 3/4
Length = 105/44
Final answer:
To find the length of the rectangle, we use the formula Area = length imes width, converting the given mixed numbers into improper fractions, and then dividing the area by the width.
Explanation:
To calculate the length of the rectangle given the width and the area, we can use the formula for the area of a rectangle: Area = length times width. To isolate the length, we divide both sides of the equation by the width. Given that the width of the rectangle is 3 2/3 feet and the area is 8 3/4 square feet, the expression to find the length is:
Length = Area / Width
First, we convert the mixed numbers into improper fractions:
Width: 3 2/3 = 11/3 feet
Area: 8 3/4 = 35/4 square feet
Then, the calculation for the length is:
Length = (35/4) / (11/3) feet
A classroom can accommodate less than 21 students.
Which of the following inequalities represents the number of students the classroom can accommodate?
Answer:
x<21
Step-by-step explanation:
How I always do it is I write down the number that was in the problem. So write down 21. Next I write down less. Then, if it says less, then the inequality sign's open side will face the number. This will be the opposite if the problem says more
The inequality representing a classroom that can accommodate fewer than 21 students is s < 21, which means the classroom can hold any number of students from 1 up to 20.
Explanation:The question asks which inequality represents the number of students a classroom can accommodate if it can hold fewer than 21 students. To express this mathematically, we use an inequality sign. Since the classroom can accommodate less than 21 students, it means the number of students (let's call this number s) must be strictly less than 21. Therefore, the inequality that correctly represents this condition is s < 21.
This inequality means that any whole number of students from 1 up to 20 can fit in the classroom, as all these values are less than 21. It's crucial to understand that the inequality does not include 21 itself, because it specifies "less than," not "less than or equal to."
