Suppose △FMN≅△HQR . Which congruency statements are true? Select each correct answer. NF¯¯¯¯¯¯≅HQ¯¯¯¯¯¯ MN¯¯¯¯¯¯¯≅QR¯¯¯¯¯ ∠M≅∠Q ∠R≅∠F ∠N≅∠M QH¯¯¯¯¯¯≅MF¯¯¯¯¯¯

Answers

Answer: \overline{MN}\cong\overline{QR}

\angle{M}\cong\angle{Q}

\overline{MF}\cong\overline{QH}

Step-by-step explanation:

We know that if two triangles are congruent , then the corresponding angles and sides are congruent by CPCTC.

Given: \triangle {FMN}\cong\triangle{HQR}

Therefore , the corresponding angles and sides of \triangle {FMN}\text{ and }\triangle{HQR} are congruent.

∠F corresponds ∠H

∠M corresponds ∠Q

∠N corresponds ∠R

⇒ ∠F ≅ ∠H

∠M ≅ ∠Q

∠N ≅ ∠R

\overline{MF}\cong\overline{QH}\n\overline{MN}\cong\overline{QR}\n\overlien{FN}\cong\overline{HR}

So , from the given options, the true congruency statements are :-

\overline{MN}\cong\overline{QR}

\angle{M}\cong\angle{Q}

\overline{MF}\cong\overline{QH}
△FMN ≅ △HQR
so
MF ≅  QH
MN ≅ QR
NF  ≅ RH
and
∠F ≅ ∠H 
∠M ≅ ∠Q
∠N ≅ ∠R

Answer
MN ≅ QR
∠M ≅ ∠Q
QH ≅ MF

Hayden is a manager at a landscaping company. He has two workers to landscape an entire park, Cody and Kaitlyn. Cody can complete the project in 8 hours. Kaitlyn can complete the project in 6 hours. Hayden wants to know how long it will take them to complete the project together. Write an equation and solve for the time it takes Cody and Kaitlyn to complete the project together. Explain each step.

Answers

Cody can do the job in  8  hours.
He does  1/8  of the job each hour.

Caitlyn can do the job in  6  hours.
She does  1/6  of the job each hour.

Working together, they do (1/8 + 1/6) of the job each hour.
Can you add those fractions ?
Change both to a denominator of  24.
1/8 = 3/24
1/6 = 4/24
                   (1/8 + 1/6) = (3/24 + 4/24) = 7/24

Working together, they do  7/24  of the job each hour.

Invert  (7/24  job/hour)  and you have  (24/7  hour/job) .

24/7  =  (3 and 3/7) hour/job.

Together, it takes them  3-3/7 hours.
(That's 3hours 25minutes 42.9 seconds.)

The question says "write an equation".

The equation could be     H (number of hours) = 1 / (1/8 + 1/6)

 

He shaded 1/3 of one rectangle and 1/4 of other rectangle. What is the least number of parts into which both rectangles could be divided?

Answers


Rectangle 1: 1/3 shaded

Rectangle 2: 1/4 shaded

First you have to look through each denominators multiples to find the lowest common denominator (LCD).

Multiples of 3: 3, 6, 9, 12, 15

Multiples of 4: 4, 8, 12, 16, 20

As you can see, both numbers are multiples of 12.

Rectangle 1: 1/3 shaded= 4/12 shaded

Rectangle 2: 1/4 shaded= 3/12 shaded

I made equivalent fractions by multiplying both the numerator and the denominator by the same number.

The least number of parts which both rectangles can be divided is 12.

Hope this helped :)
