Answer:
1.2 hours, or 72 minutes
Step-by-step explanation:
If David drove for 1.5 hours at 36 mph, that means that he traveled a distance of (36*1.5) = 54 miles.
If he takes the same route at a speed of 45 mph instead, he will reach his destination in (54/45) = 1.2 hours, which is equivalent to 72 minutes.
Answer:
1.2 hours
Step-by-step explanation:
to find distance for 36 mph
0.5 hour is 18 miles
so 36m+18m
= 54 miles for 1.5 hours
and to find time for 45 mph
[tex]54 \div 45 = \frac{6}{5} \\ = 1.2[/tex]

Answer:
m<PRQ=15°
Step-by-step explanation:
so we're given that PQ and RQ are sides of a regular 12-sided polygon (dodecagon)
a regular polygon is a polygon that has all angles be the same measure AND have all sides be the same length
because of that, PQ=RQ, and ΔPQR is isoceles
now we need to find what the question is asking for: m<PRQ
because of base-angles theorem, m<PRQ=m<RPQ
we need to find m<PQR
a dodecagon is 1800° in measure
and we need 1/12th of that measure, since <PQR is 1 out of the 12 interior angles on the dodecagon (a dodecagon has 12 vertecies, so 12 angles). Also because the polygon is regular, every interior angle has the same measure.
so find the measure of <PQR
<PQR= 1/12*1800=150°
now to find the measure of <PRQ:
there are 180° in a triangle
so subtract 150° from 180°
180°-150°=30°
30° is the sum of the base angles (<PRQ is one of the base angles in a triangle)
the base angles are the same measure, so that means the measure of <PRQ is 1/2 the measure of the sum of the base angles
therefore m<PRQ=15°
hope this helps!

Answer:
104.06 m^2
Step-by-step explanation:
Area of square
22 X 22 = 484 m^2
Area of circle
3.14r^2
radius = 22/2
radius = 11
3.14* 11^2 = 379.94
484 - 379.94 = 104.06

To solve the equation 34x=15, Abby multiplied both sides by ¾ and got a solution of x=1114. Explain the error that Abby made and then find the correct value of x.
Answer:
x = 20
Step-by-step explanation:
3/4x = 15
Abby's calculation:
3/4x = 15
Multiply both sides by 3/4
x = 1114
Abby's error was multiplying both sides by 3/4 instead of dividing both sides by 3/4 to get the value of x
Correct calculation:
3/4x = 15
Divide both sides by 3/4
3/4x ÷ 3/4 = 15 ÷ 3/4
x = 15 × 4/3
x = 60/3
x = 20
Check:
3/4x = 15
3/4*20
= (3*20) / 4
= 60/4
= 15
3/4*20 = 15
Las longitudes de dos lados de un octágono regular están representadas por las expresiones 2x + 4 y 3x-8. Encuentra la longitud de un lado del octágono
Answer:
La longitud del lado del octágono es de 28 unidades.
Step-by-step explanation:
Si las longitudes de los dos lados pertenecen a un octágono regular, entonces se satisface la siguiente condición:
[tex]2\cdot x + 4 = 3\cdot x - 8[/tex] (1)
A continuación, despejamos [tex]x[/tex] en (1):
[tex]3\cdot x - 2\cdot x = 4 + 8[/tex]
[tex]x = 12[/tex]
Ahora, determinamos la longitud del lado del octágono: ([tex]x = 12[/tex])
[tex]l = 2\cdot x + 4[/tex]
[tex]l = 28[/tex]
La longitud del lado del octágono es de 28 unidades.

a spinner has 8 equal sections,6 are green .find probability that will land on green
Answer:
P(A) and P(B) = P(A) x P(B)
P(A) = number gray/total number of sections = 6/8 = 3/4
P(B) = number of reggae songs/total number of songs = 2/8 = 1/4
P(A) and P(B) = (3/4)(1/4) = 3/16
Step-by-step explanation:
Answer: 3/4 (0.75)
Step-by-step explanation:
6 out of 8 sections are green.
So there is a 6/8 probability that it will land on green.
6/8 = 3/4.

Answer:
h = 3 cm
Step-by-step explanation:
The volume (V) of a rectangular prism is calculated as
V = Ah ( A is the area of the base and h the height )
Here V = 36 and A = 6 × 2 = 12 cm² , then
12h = 36 ( divide both sides by 12 )
h = 3
Answer: 3 cm
Step-by-step explanation:
The formula to solve the volume of a rectangular prism is V = l x w x h
Where V is volume, l is length, w is width, and h is height
Givens are, Volume = 36 cm3
length = 6 cm
width = 2 cm
Now, we will plug in the numbers to the formula
36 cm3 = 6cm x 2cm x h
36 cm3 = 12 cm2 x h
divide 12cm2 on both sides
36cm3/12cm3 = h
h = 3cm
Explain why triangle ABC is similar to triangle CFE
Answer:
It's exactly the same, except the size
Step-by-step explanation:
Answer:
They are similar because if you look at the length of 2 of the sides that you know
Triangle ABC has side length 1 and 2 or 1:2
CFE has sides length 2 and 4 or 2:4 and 2:4 can also be written as [tex]\frac{2}{4}[/tex] which is a fraction, and fractions can be simplified to 1:2.
So they are similar but just one is bigger then the other.
