Hilary is ordering a large circular pizza from her local pizza shop. She asks about the size of the pizza and is given three different values: 14 inches, 44 inches and 7 inches.
Hilary knows three measurements that are used to describe circles: radius, diameter and circumference. Which value best matches each measurement? Explain your reasoning.
Answers
Answer:
7 is the radius
14 is the diameter
44 is the circumference
Step-by-step explanation:
7 is the smallest number of them all so it's the radius. The diameter is double of a radius so 14 is the diameter and finally 44 is the circumference :)
14 in is the diameter
44 in is the circumference
7 has to be the radius because the radius is half the diameter. this in turn means that the diameter must be 14. and the circumference is 44 because the circumference is the perimeter of the circle. (it has to be the largest number)

Answer:
1) = 2hrs and 30mins
2) = 130miles
Step-by-step explanation:
1) 60mi/hr, total driven 150miles
so at 120miles thats 2 hours. 30 miles is 30 minutes
60+60+30=150miles
2) 40miles/hr you drove 2 hours at 40 miles
40+40 =80miles
50miles/hr you drove 1 hour st 50 miles
40+40+50 = 130miles
Answer: 1) 2.5 hours, 2) 130 miles
Step-by-step explanation:
To solve both of these problems, let us remember the formula:
Distance = (speed) × (time)
1) Plug in the numbers into the formula:
150miles = (30miles/hour) × (time)
Divide both sides by 30miles/hour to solve for time:
150miles/(30miles/hour) = time
Simplify:
2.5hours = time
2) Susan's driving is broken into two parts with different speeds and time.
Solve the distance for first drive by plugging numbers into formula:
Distance = (40miles/hour) × (2hours)
Multiply:
Distance of first drive = 80miles
Solve for distance of second drive:
Distance = (50miles/hour) × (1hour)
Multiply:
Distance of second drive = 50miles
Add distance of first drive and second drive:
80miles + 50miles = 130miles

(1) opens upward and is wider
(3) opens upward and is narrower
(2) opens downward and is wider
(4) opens downward and is narrower
Answers
The function opens upward and is narrower, because we have a vertical dilation.
How is the function transformed?
For a function f(x), a vertical dilation of scale factor k is:
g(x) = k*f(x).
if k > 1, we have a dilation.if 0 < k < 1, we have a contraction.In this case, the scale factor is a, and we know that a > 1, so we have a dilation.
Then the correct option is 3, the function still opens upwards (because a is positive) and is narrower.

Answer:
Hours after sunrise Temperature
5 -8.5
7 -7.5
8 -9.75
10 -14.25
Step-by-step explanation:
The temperature rose by 1/2 degrees from -11 degrees for 7 hours, so it would be:
-11 + 1/2(5) = -11 + 2.5 = -8.5, so -9.5 degrees 5 hours after sunrise
For 7 hours it would be -11 + 1/2(7) = -11 + 3.5 = -7.5
After 7 hours, it started to decrease by 2 1/4 degrees per hour for 3 hours, so:
-7.5 - 2.25(1) = -8.5 - 2.25 = -9.75
For 10, it would be:
-7.5 - 2.25(3) = -7.5 - 6.75 = -14.25

D. ∠1 = 34° , ∠2 = 146°, ∠3 = 34°
DONT PUT NONSENSE ANSWERS
Answers
Answer:
B
Step-by-step explanation:
∠4 and ∠2 are vertical angles
Vertical angles are congruent
Which means that because ∠4 = 34°, ∠2 also = 34°
∠1 and ∠4 are supplementary angles.
Supplementary angles add up to equal 180
Which means that ∠1 + ∠4 = 180
or ∠1 + 34° = 180
subtract 34 from each side
180 - 34 = 146
Hence, ∠1 = 146
∠1 and ∠3 are vertical angles
Like stated before vertical angles are congruent
Which means that because ∠1 = 146°, ∠3 also = 146
So we can conclude that the answer is B
Answer:
B) <1 = 146, <2 = 34, <3 = 146
Step-by-step explanation:
Because measure angle 4 is 34°
And the angle opposite of <4 is <2 and they’re both congruent so <4 = <2. Therefore, <2 = 34.
By finding <1 and <3 is simply finding a supplementary angle because:
<4 + <1 = 180°
<4 + <3 = 180°
So,
34 + <1 = 180°
<1 = 146°
and,
34 + <3 = 180°
<3 = 146

Maryanne is making a friendship necklace at summer camp using 1.6 cm beads. What is a reasonable estimate for the length if she uses 24 beads?
Answers
Answer:
38.4
Step-by-step explanation:
1.6 times 24 is 38.4
The reasonable estimation for the length if she used 24 beads will be 38.4 cm.
What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers by each other to find a new multiplied number.
Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.
As per the given,
Length of one bead = 1.6 cm
Number of beads = 24
Reasonable length = 24 x 1.6 = 38.4 cm.
Hence "The reasonable estimation for the length, if she used 24 beads, will be 38.4 cm".
