Answer: 50 miles per hour

Step-by-step explanation:

Find out the length of the normal route.

Distance = Speed * time

= 48 * 40/60

= 32 miles

The detour is 8 miles longer so the length is;

= 32 + 8

= 40 miles

What speed should he travel at to make it in 48 minutes. Remember speed is in miles per hours.

Speed = Distance/ time

= 40 / (48/60)

= 50 miles per hour

Answer:

50 miles per hour :)

Step-by-step explanation:

Distance = Speed * time = 48 * 40/60 = 32 miles

Detour is 8 miles longer so = 32 + 8 = 40 miles

In 48 minutes. Remember speed is in miles per hours.

Speed = Distance/ time

50MPH= 50 miles per hour

Answer:

C.) 4 sqrt2

Step-by-step explanation:

ON=MN

therefore you can use pythagereum theorum here in a right triangle

as the hypotnuese is 8 you know that ON and MN is equal to the sqrt of 32 each. As A^2+ B^2=C^2

C=8 so C^2= 64 therefore,

A^2+ B^2=64 therefore,

A^2= 32 and B^2=32

you take the sqrt of 32 you get 4sqrt2

Answer:

- 2 feets

Step-by-step explanation:

Given that sea star can be found at an ocean depth of 2 feets ;

An ocean depth of 2 feets can be represented as :

Sea level - depth = 0 - 2 = - 2 feets

Hence, it can be concluded that sea star lives in the ocean

Answer:

12 hat/scarf outfits

Step-by-step explanation:

If a snowman has 3 old felt hats and 4 scarves from which to choose, how many different hat/scarf outfits can he wear?

We solve this question using the fundamental counting principle.

This states that:

When we have two events, a and bthe number of ways both events can happen is a × b

From the above question, our two events is

a = 3 old felt hats

b = 4 scarves

Hence, the different hat/scarf outfits can he wear is given as

3 × 4 = 12 hat/scarf outfits

Answer:

C. 8

Step-by-step explanation:

f(5) =1/4(2)^5

because x=5

f(5)=1/4(32)

because 2^5 is 2*2*2*2*2=32

f(5)=8

because 1/4*32 or 32/4 is 8

Hope this helped :) I haven't even learned f(x) in school yet haha. I'm in 8th grade, but I took extracurriculars for math and I'm on the math team. Ergo, I know it's right!

Answer:

m = n = 20

Step-by-step explanation:

Here, we want to find the missing side lengths

For a 45-45 triangle, the lengths have a side ratio of;

1:1: √2

We should understand that the triangle is isosceles ( opposite and adjacent are equal)

So n = m

So what we just need to do here is divide 20 √2 by √2

Mathematically, that would be;

20 √2/√2 = 20

Step-by-step explanation:

d=(3/4)-(1/4)=(5/4)-(3/4)=(7/4)-(5/4)=1/2

then it is an arithmetic sequence

by using this equation :

a(n) = a1 +(n-1)d

and we have : a1=(1/4),  d=(1/2)

So:

Explicit formula: a(n) = (1/4) +(n-1)*(1/2)

Answer: 6 × 4^x

Step-by-step explanation:

From the question, we are told that scientists released 6 rabbits into a new habitat in year 0 and that each year, there were four times as many rabbits as the year before.

The number of rabbits there after x years will be:

= 6 × 4^x

For example, let us say we want to calculate the number of rabbits after 2 years.

= 6 × 4^x

= 6 × 4²

= 6 × 16

= 96 rabbits

Answer:

DE ≅ XY and XY ≅ YZ, then DE ≅ YZ

Thus, this statement is illustrated or validated by the 'Transitive Property of Segment Congruence'.

Step-by-step explanation:

We know that if two segments are congruent to the third segment, then they will be congruent to each other. This is called Transitive Property of Segment Congruence.

For example, Let suppose

LM ≅ AB and AB ≅ BC, then LM ≅ BC

30  ≅ 30 and  30  ≅ 30, then 30  ≅ 30

Thus, this validates the 'Transitive Property of Segment Congruence'.

Now Given

DE ≅ XY and XY ≅ YZ, then DE ≅ YZ

Thus, according to the above discussion, this statement is illustrated or validated by the 'Transitive Property of Segment Congruence'.

When you catch up, the distance traveled is the same

Distance = rate x time

r = uncle's rate

30 min = 30/60 hr = uncle's time

25 min = 25/60 hr =  your time

Uncle's distance = Your distance

(r)(30/60) = (r + 10)(25/60)

(r)(1/2) = (r + 10)(5/12)

r/2 = 5r/12 + 50/12  

6r = 5r + 50

r = 50  

Uncle's rate = 50 mph

Your rate = 50 + 10 = 60 mph

Answer:

The answer is A. 48.7

Step-by-step explanation:

The approximate circumference of the circle is,

⇒ C = 48.7 cm

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

A circle is shown in image.

And, Diameter of circle = 15.5 cm

Since, WE know that;

Circumference of circle is,

C = πd

Where, d is diameter of circle

Hence, The approximate circumference of the circle is,

⇒ C = 3.14 × 15.5

⇒ C = 48.7 cm

Thus, the circumference of the circle is,

⇒ C = 48.7 cm

Answer:

I looked it up and it said 0.5

Understanding:

This can be easily solved by using the distance formula which is

[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }\\[/tex]

[tex]d:[/tex] distance

[tex](x_{1},y_{1}):[/tex] coordinates of the first point, in our case it is [tex](1,-5)[/tex]

[tex](x_{2},y_{2}):[/tex] coordinates of the second point, [tex](4,-1)[/tex]

Solution:

[tex]d=\sqrt{[(4)-(1)]^{2}+[(-1)-(-5)]^2}\\=\sqrt{(3)^2+(4)^2}\\= \sqrt{9+16} \\=\sqrt{25}\\= 5[/tex]

The distance between the two points is 5.
