Answer:
Reduction scale
Step-by-step explanation:
Enlarging scale means that the drawing is larger than the actual object. Hence the representative fraction will be greater than unity. For reducing scale the representative fraction is less than unity.
So now looking at 1:25, we see it's a reduction scaling because it's fraction is less than unity.
And what 1:25 means is that 1 on paper while the actual size of the object is 25

A vase with a circular base exerts a force of 15 N on a table with a pressure of 700 N/m2.
Find the radius of the base of the vase in cm to 2 dp.
Final answer:
The radius of the base of the vase is 19.5 cm.
Explanation:
To find the radius of the base of the vase, we can use the formula for pressure: pressure = force/area. In this case, the force exerted by the vase on the table is 15 N and the pressure is 700 N/m². Let's assume the base of the vase is a circle. The area of a circle is given by the formula A = π r², where r is the radius of the circle.
So, we can rearrange the formula for pressure to solve for the radius:
r = √(force/pressure) = √(15 N / 700 N/m²) = 0.195 meters.
To convert the radius from meters to centimeters, we multiply by 100: 0.195 meters * 100 = 19.5 centimeters. Hence, the radius of the base of the vase is 19.5 cm.
Final answer:
By applying the pressure formula and solving for the radius, the calculated radius of the base of the vase comes out to be approximately 8.26 cm to two decimal places.
Explanation:
To find the radius of the base of the vase, we need to use the formula for pressure, which is pressure (P) equals force (F) divided by area (A). The formula can be expressed as:
P = F / A
We have been given the pressure and the force, and the area of a circle is equal to π × radius^2 (πr^2). By substituting the known values into the pressure formula and solving for the radius, we get:
700 N/m2 = 15 N / (πr^2)
r^2 = 15 N / (700 N/m^2 × π)
r = √(15 / (700 × π))
Now, calculate the numerical value of the radius:
r = √(15 / (700 × 3.14159))
r ≈ √(0.0068194)
r ≈ 0.082595 cm
To present our answer in centimeters to two decimal places:
r ≈ 8.26 cm
Inequality stuff... look at image for the question. An explanation would also be nice, but you can comment it along with the answer.
Will give Brainliest for the correct answer! :]
Answer:
x>-8
Step-by-step explanation:
When you multiply (or divide) both sides of an inequality by a negative number (in this case -1), you need to flip the inequality symbol. For instance in this case, -x<8 is the same as x>-8. This is because you know that if -x is less than 8, if x is less than -8 then the inequality wouldn't be true any longer. This can be demonstrated with an example: Say that x is -10. -(-10) is 10, and no longer smaller than 8. Therefore, x>-8. Hope this helps!

The temperature in a greenhouse should be 65 degrees or higher. One morning, the heater stopped working. The temperature dropped 6 degrees before someone fixed the heater. The temperature was still at least 65 degrees when the heater started working again. How can you best describe the temperature in the greenhouse before the heater stopped working?
The temperature in the greenhouse before the heater stopped working was at least 71 degrees Fahrenheit, based on the information that the temperature dropped 6 degrees but remained at least 65 degrees.
Explanation:As the temperature dropped 6 degrees and was still at least 65 degrees when the heater was fixed, we can set up a simple inequality to represent this situation:
Let T represent the temperature before the heater stopped working. After the heater stopped working and the temperature dropped by 6 degrees, the new temperature would be T - 6. According to the provided information, this new temperature was still at least 65 degrees, which gives us the inequality:
T − 6 ≥ 65
Adding 6 to both sides of the inequality, we find:
T ≥ 71
This means that the temperature in the greenhouse before the heater stopped working was at least 71 degrees.

If a dog is tied to a rope 15 feet long, how can it reach a bone
30 feet away? The rope isn't
T
E - TO - N - -HI-
5.4
13.4
8.6
10.6 1.4
10
Answer:
The other end of the rope was not tied to anything
Step-by-step explanation:
The dog was tied to a rope of 15 feet long and the bone was 30 feet away from where he was tied. The rope used to tie the dog is 15 ft long . But the other end of the rope wasn't tied to anything, this simply means the dog can easily approach and get the bone 30 ft away from where it was tied.
The other end of the rope was not tied to anything . This implies that the dog can simply reach the bone without breaking a sweat. The 15 feet rope was only tied to the dog , so it does not stop the dog from reaching a bone that is 30 ft away.

4(2x-3)=4
Answer:
x=2
Step-by-step explanation:
Let's solve your equation step-by-step.
4(2x−3)=4
Step 1: Simplify both sides of the equation.
4(2x−3)=4
(4)(2x)+(4)(−3)=4(Distribute)
8x+−12=4
8x−12=4
Step 2: Add 12 to both sides.
8x−12+12=4+12
8x=16
Step 3: Divide both sides by 8.
8x /8 = 16 /8
x=2
Answer:
x = 2
Step-by-step explanation:
4(2x-3) = 4
⇔
4 × (2x-3) = 4 × 1
⇔
(2x-3) = 1 (divide both sides by 4)
⇔
2x = 1 + 3 (Move 3 to the right hand side)
⇔
2x = 4
⇔
x = 4/2
⇔
x = 2
A spa charges $125 for a one hour massage and $250 for a
pedicure + 90-minute massage package. One day, the spa had
27 customers and made $5,250.
How many massages, x, and pedicure + 90-minute massage
packages, y, did the spa perform? Express your answer as an
ordered pair (x,y).
Enter the answer
Let x represent number of massages and y represent number of pedicure + 90-minute massage packages.
We have been given that a spa charges $125 for a one hour massage, so amount earned from x massages would be [tex]125x[/tex].
The spa charges $250 for a pedicure + 90-minute massage package, so amount earned from y pedicure + 90-minute massages will be [tex]250y[/tex].
We have been given that one day the spa had 27 customers. We can represent this information in an equation as:
[tex]x+y=27...(1)[/tex]
[tex]y=27-x...(1)[/tex]
Since spa made $5,250, so amount earned from both massages would be equal to 5,250. We can represent this information in an equation as:
[tex]125x+250y=5250...(2)[/tex]
Upon substituting equation (1) in equation (2), we will get:
[tex]125x+250(27-x)=5250[/tex]
Let us solve for x.
[tex]125x+6750-250x=5250[/tex]
[tex]-125x+6750=5250[/tex]
[tex]-125x+6750-6750=5250-6750[/tex]
[tex]-125x=-1500[/tex]
[tex]\frac{-125x}{-125}=\frac{-1500}{-125}[/tex]
[tex]x=12[/tex]
Upon substituting [tex]x=12[/tex] in equation (1), we will get:
[tex]y=27-12=15[/tex]
Therefore, the spa performed 12 one hour massages and 15 pedicure + 90-minute massage packages that is [tex](12,15)[/tex].

A right triangle has legs that both measure 14 inches. What is the length of its hypotenuse to the nearest whole number?
5 inches
19 inches
20 inches
28 inches
So, to find this answer, we want to use Pythagorean Theorem!
The formula for this theorem is: a²+b²=c².
· It's important to note that c² is always your hypotenuse, while a and b are your legs.
So, all we need to do is (1) plug in our values, (2) square them, (3) isolate them, and (4) find the square root of our final number!
--------------------------------------------------------------------------------------------------------------
14²+14²=c²
14² = 196
We want to isolate our C, but we can't do that with the squared symbol, so in order to remove a squared symbol, we need to square root both sides.
196 = c²
√196 = 14
C = 14
What are the x- and y-intercepts of the function graphed below?*
(0, 3) and (6,0)
(3,0) and (0,6)
(3,0) and (6.0)
(0.3) and (0,6)
Answer:
(3,0) and (0,6)
Step-by-step explanation:
(x,y) is the only way to make ordered pair.
The x was a 3 so you could cross out the first and last because they put the 3 in the y spot. When is should be (3,0).
Then the y was 6 and that I would be (0,6) so the third would also be crossed out because they put the 6 in the y spot.
So the answer is (3,0) and (0,6).

The cargo loads that Niels transports in his truck have a mean weight of 42,000 lb with a standard
deviation of 1,500 lb.
What will be the mean and standard deviation of the distribution of weights in kilograms?
1 lb approximately equals 0.45 kg.
Choose 1 answer:
A-Mean: 18,900 kg
Standard deviation: 675 kg
B-Mean: 18,900 kg
Standard deviation: 1,500 kg
C-Mean: 42,000 kg
Standard deviation: 675 kg
D-Mean: 42,000 kg
Standard deviation: 1,500 kg
Answer:A
Step-by-step explanation:multiply 42,000x0.45 and 1,500x0.45!
Final answer:
The mean weight of Niels' cargo loads in kilograms is 18,900 kg and the standard deviation is 675 kg, making the correct answer A.
Explanation:
To convert Niels' cargo loads from pounds to kilograms, we multiply the mean weight and the standard deviation by the conversion factor of 0.45 kg/lb.
The mean weight in kilograms is calculated as follows:
Mean (kg) = 42,000 lb × 0.45 kg/lb = 18,900 kg
The standard deviation in kilograms is calculated as follows:
Standard deviation (kg) = 1,500 lb × 0.45 kg/lb = 675 kg
Therefore, the correct answer is A: Mean: 18,900 kg, Standard deviation: 675 kg.

Marble Slab Creamery is creating a cone-shaped paper wrapper for its new green Baby Yoda waffle cone. The wrapper should have a radius of 5 cm and a slant height of 10 cm. One location wants to offer the cones a weekend earlier, so they plan to make the cone-shaped wrappers for first 25 waffle cones sold that Saturday. About how many square cm of wrapper paper will they need?
Answer:
3927 square cm
Step-by-step explanation:
We want to find the area of the lateral part of the cone with radius 5 and slant height 10. The equation needed is: L = πrl, where r is the radius and l is the slant height. Plug the given values in:
L = πrl
L = π * 5 * 10 = 50π square cm
We want 25 of these, so multiply 50π by 25:
50π * 25 ≈ 3926.99 square cm ≈ 3927 square cm
