Answers
Answer:
∠1 ≅ ∠2 ⇒ proved down
Step-by-step explanation:
#11
In the given figure
∵ BA // CF
∵ BC is a transversal
∵ ∠1 and ∠BCF are interior alternate angles
∵ The interior alternate angles are equal in measures
∴ m∠1 = m∠BCF
∴ ∠1 ≅ ∠BCF ⇒ (1)
∵ BC // ED
∵ CF is a transversal
∵ ∠BCF and ∠2 are corresponding angles
∵ The corresponding angles are equal in measures
∴ m∠BCF = m∠2
∴ ∠BCF ≅ ∠2 ⇒ (2)
→ From (1) and (2)
∵ ∠1 and ∠2 are congruent to ∠BCF
∴ ∠1 and ∠2 are congruent
∴ ∠1 ≅ ∠2 ⇒ proved

Students at Mendel Middle School are planning a fair for their school's fundraiser. Liam volunteers to help plan the event. The first month, he volunteered for x hours. The next month, he volunteered for 1 2/3 times as many hours as he had the first month. If he volunteered for a total of 40 hours, how many hours did he volunteer during the first month? Write an equation to represent the situation and solve.
Answers
Answer:
15 hours
Step-by-step explanation:
[tex]x[/tex] is the number of hours that Liam volunteered in the first month
The next month he volunteered [tex]1\dfrac{2}{3}[/tex] times the time he volunteered the first month.
Total time he volunteered in the two months is 40 hours so
[tex]x+1\dfrac{2}{3}x=40\\\Rightarrow x+\dfrac{5}{3}x=40\\\Rightarrow \dfrac{3x+5x}{3}=40\\\Rightarrow x=\dfrac{40\times 3}{8}\\\Rightarrow x=15[/tex]
Time he volunteered in the first month is 15 hours.

A local school donated canned goods to help the community. Cans were packed into boxes each weighing 16.4 pounds. The volunteers packed 9 boxes. How many total pounds of food did they collect? A. 97.6 B. 147.6 C. 976 D. 1,476
Answers
Answer:
147.6 pounds of foodStep-by-step explanation:
Each box weighed 16.4pounds, if the volunteers packed 9 boxes, we need to calculate the total pounds of food collected. Using the equality postulate;
1 box = 16.4 pounds
9 boxes = x pounds of food
Cross multiply;
1 * x = 9 * 16.4
x = 147.6 pounds of food
Hence the volunteers collected 147.6 total pounds of food

What value of x satisfies the equation x/4 + x/2 =9
Answers
"12" is the correct value of "x" which satisfies the given equation.
The given equation is:
→ [tex]\frac{x}{4} +\frac{x}{2} =9[/tex]
By taking L.C.M, we get
→ [tex]\frac{x+2x}{4}= 9[/tex]
→ [tex]\frac{3x}{4} =9[/tex]
By applying cross-multiplication, we get
→ [tex]3x=36[/tex]
→ [tex]x = \frac{36}{3}[/tex]
→ [tex]= 12[/tex]
