Did the scale factor of 0.75 enlarge reduce or stay the same?
Answer:
[tex]\huge\boxed{\sf Reduces}[/tex]
Step-by-step explanation:
Since the scale factor of 0.75 is less than 1, So the dilated image is a reduced image.
Thus the scale factor of 0.75 reduces the dilated image.

what is the maximum number of cubes with side lengths of 1/2 cm that can fit into a right rectangular prism with base dimensions of 12 1/2 cm by 8 1/2cm and a height of 9 1/2cm?
Answer:
8075.
Step-by-step explanation:
Volume of the prism
= 12 1/2 * 8 1/2 * 9 1/2
= 25/2 * 17 / 2 * 19/2
= 8075/8 cm^3
The volume of the small cubes = (1/2)^3 = 1/8 cm^3
So the number required = 8075 / 8 / 1/8
= 8075*8 / 8
= 8075.

Step-by-step explanation:
Answer:
x = 3, y = -2.
Step-by-step explanation:
5x + 6y = 3
2x - 3y = 12 Multiply this by 2:
4x - 6y = 24 Now add this to the first equation:
9x = 27
x = 3.
Substitute x = 3 in the second equation:
2(3) - 3y = 12
-3y = 12 - 6 = 6
y = 6 / -3
y = -2.

A local restaurant only sells burgers and cokes. 3 burgers and 5 comes cost $17, while 6 burgers and 9 cokes cost $33. What’s the price of a burger?
Answer:
The price of a burger is $4 and that of cone is $1.
Step-by-step explanation:
Let the cost of burger is x and that of cone is y.
ATQ,
3x+5y = 17 ....(1)
And
6x + 9y = 33 ...(2)
Multiply equation (1) by 2.
6x + 10 y = 34 ...(3)
Subtract equation (2) from (3)
6x + 10 y-(6x + 9y) = 34 - 33
6x + 10 y-6x- 9y = 1
y = 1
Put the value of y in equation (1)
3x+5 = 17
3x = 12
x = 4
So, the price of a burger is $4 and that of the cone is $1.

Is a²b the same thing as ba² ?
Please explain. Thanks so much!
a²b is the same thing as ba²
b and a are two separate variables lets pretend a is 2 and b is 3
2² * 3 = 4 * 3 = 12
3 * 2² = 3 * 4 = 12
this is the commutative property of multiplication

How many different triangles ABC can be formed if C=60∘, c=17√3 and a=34?
Answer:
Jordan, Its been 5 hours, whats the answer?
Step-by-step explanation:
There can be only 1 triangle formed by the given information.
What is triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon.
Given that, ABC can be formed if C=60∘, c=17√3 and a=34
Using the sine law for triangle,
A/sina = B/sinb = C/sinc
34/sina = 17√3/sin60°
⇒ sina = 90°
Since, The triangle ABC is a right triangle,
Hence, There can be only 1 triangle formed by the given information.

A model of a skyscraper uses the scale of 2 inches = 45 feet. If the actual skyscraper is 992 feet tall, how tall is the model?
Answer:
44.08 or 44.1
Step-by-step explanation:
OK so the basics of this question is that for every 45 feet of the actual skyscraper we have 2 inches in the model. The first thing we do is divide 992/45 which equals 22.04. Know if this was 1 inch for every 45 feet we would be done however we need to multiply this number by 2 to get our answer so 22.04*2 =44.08

if the probability of picking a pink jelly bean out of a bag is 4/15, what is the probability of not picking a pink jelly bean
Answer:
The probability of not picking a pink jelly bean: 11/15
Step-by-step explanation:
As we know that the maximum value of the probability of an event would always be 1.
The reason is that '1' is certain that something would happen.Given that the probability of picking a pink jelly bean out of a bag is 4/15.
Thus, the probability of not picking a pink jelly bean can be calculated by subtracting 4/15 from the maximum probability '1'.
i.e.
Probability of not picking a pink jelly bean = max probability - 4/15
= 1 - 4/15
= 11/15
Therefore, the probability of not picking a pink jelly bean: 11/15

plz help asap i will do brainliest!!! A car takes 4 hours to reach a destination travelling at the speed of 63 km/h. How long will it take to cover the same distance if the car travells at the speed of 56 km/h? Do these quantities (time and speed) vary directly or inversely? Find the constant of variation.
Answer:
A car takes 4 hours to reach a destination travelling at the speed of 63 km/h.
Speed = distance / time
Distance = speed × time
Distance it took the car, travelling for 4 hours to a destination at a speed of 63 kilometers per hour would be
4 × 63 = 252 kilometers.
if the car travels at a different speed of 56 kilometers per hour and the distance remains 252 kilometers, the time it takes will be
Time = distance / speed
= 252/56 = 4.5 hours
The time varies inversely with the speed. The more the speed, the lesser the time and the lesser the speed, the more the time.
Let speed = s and let time = t
s varies inversely with t
Introducing constant of inverse variation k, it becomes
s = k/t
When s = 56, t = 4.5
56 = k/4.5
k = 4.5 × 56 =252
This is the distance
