Student Are Knitting Scarcer For A Fund-raiser.Elaine Can Kinit 4 Scarves In 20 Days.Mario Can Knit 2

Answers

Answer 1
Elain can knit 4 scarves in 20 days. In 40 days, she would knit 8 scarves.

If Mario can knit 2 more scarves than she can in 40 days, then he can knit 10 scarves.

Divide the days by the scarves, to find that Elain knits one scarf in 5 days, and Mario knits one scarf in 4 days.

Hope this helped, and dm(?) me if you want me to elaborate!

Julia left school and travel toward the train station. One hour later Carlos left traveling at 30 mph in an effort to catch up to Julia. After traveling for two hours Carlos finally caught up. Find Julie is average speed

Answers

speed = distance/time

distance = speed * time

Carlos traveled for 2 hours.
Julia traveled for 1 more hour, or 3 hours

Carlos:
time = 2
distance = d
speed = 30 mph

distance = speed * time
d = 30 * 2
d = 60 miles

They both traveled 60 miles.

Julia:
time = 3
distance = 60 miles
speed = s

speed = distance/time = (60 miles)/(3 hours) = 20 mph

Julia's speed is 20 mph.

Which graph represents the function f(x) = −|x − 2| − 1?

Answers

the 3rd one in the picture

Answer:

option 3

Step-by-step explanation:

[tex]f(x) = -|x -2| - 1[/tex]

The given equation is in the form of [tex]f(x) = a|x -h|+k[/tex]

where (h,k) is the vertex .

[tex]f(x) = -|x -2| - 1[/tex]

h=2 and k=-1 . the value of a=-1

Since the value of 'a' is negative so the graph will be upside down

option 3 is upside down and vertex at (2,-1)

So option 3 graph represents the function

Square ABCD is reflected across the x-axis and then dilated by a scale factor of 2 to form square A"B"C"D".

Answers

The one with a dilation because a dilation is does not result in congruent figures....but rather similar figures

Answer:

A, B and D

Step-by-step explanation:

Any Geometric figure whether translated (slid), rotated  or reflected (flipped) maintains its size since those geometric transformations just dislocate, so they remain congruents. But when a square is dilated, the following outcome is a similar one.

So, in A, B, D we have similar figures, not congruent. In A, B we have smaller squares and in D we have a bigger one.

Answers

It’s the third option pretty sure

Answer:

option: C is correct.

Step-by-step explanation:

We are given a information as:

Samuel recorded the number of different types of pets his friends have in the table shown below:

Cats 5

Dogs 3

Rabbits 1

Guinea Pigs 3

The plot based on this information will be:

A line with 4 tick marks labeled Cat, Dog, Rabbit, and Guinea Pig. Cat has 5 crosses ( since it is observed that there were 5 cats) , Dog has 3 crosses, Rabbit has 1 cross, and Guinea Pig has 3 crosses. The line is labeled Number of Pets, and title of graph is Pet Owners.

Hence, option: C is correct.
