you have 480 roses and 24 of them dies, how many per cent died?
Answer:
5%
Step-by-step explanation:
5% of the roses died.
480 roses = Total number of roses
24 roses = number of roses that died
24 roses that died as a percent of 480 the total is:
24/480*100= 5%
To find the percent of roses that died, we take the number of roses that died and divide it by the total amount of roses there are and multiply it by 100 to find the percent.
Final answer:
To find out the percentage of roses that died, you can use a proportion where 24 out of 480 roses is equal to x out of 100, and solve for x, resulting in 5% of the roses that died.
Explanation:
To calculate the percentage of roses that died, you can set up an equivalent fraction that compares the number of dead roses to the total number of roses, with 100 as the denominator. In this case, 24 roses died out of 480. The fraction for this scenario is 24/480, and you want to find out how this fraction translates to a percentage.
To do this, you would set up a proportion like this:
24/480 = x/100
Cross-multiply to solve for x, which represents the percentage of dead roses:
24*100 = 480*x
2400 = 480*x
x = 2400/480
x = 5
So, 5% of the roses died.

Congruent angles must satisfy which of the following conditions?
A. The sum of their measures is 90°
B. They have the same angle measure.
C. They share a vertex and a side.
Answer:
B
Step-by-step explanation:
Congruent angles are angles that have the same measure. This is the primary condition that they satisfy. The sum of their measures being 90° or sharing a vertex and a side don’t necessarily define congruent angles.
Explanation:In the field of Mathematics, particularly in geometry, congruent angles are those which satisfy the condition of having the same angle measure. This implies that their measures, when compared, are equal. The other options you mentioned, like the sum of their measures being 90° or sharing a vertex and a side, don’t necessarily apply to all congruent angles. For instance, for two angles to sum to 90°, they would be complementary, not necessarily congruent.

What is the value of din millimeters?
A)
27 mm
B)
12 mm
C)
9 mm
D)
13 mm
Answer: B) 12
Step-by-step explanation: In order to solve this you have to know the scale factor between the two triangles. In order to do that you just need to take a similar side between the two triangles and divide them. For example:
10 / 15 = .6666
This is RW divided by RT
Now that you have the scale factor, you just need to multiply it by 18 to get WV.
18 x .666666 = 12
The value of d in millimeters is 12 mm and this can be determined by using the similar triangle property.
Given :
Triangle RST is similar to triangle RVW.The length of the segment RW = 10 mmThe length of the segment WT = 5 mmThe length of the segment TS = 18 mmThe following steps can be used in order to determine the value of d in millimeters:
Step 1 - The similar triangle property can be used in order to determine the value of d in millimeters.
Step 2 - Apply the similar triangle property on the triangle RST and triangle RVW.
[tex]\rm \dfrac{RW}{WV}=\dfrac{RT}{TS}[/tex]
Step 3 - Substitute the values of the known terms in the above expression.
[tex]\rm \dfrac{10}{d}=\dfrac{15}{18}[/tex]
Step 4 - Simplify the above expression.
[tex]\rm d = \dfrac{10}{15}\times 18[/tex]
d = 12 mm

Which describes how triangle FGH could be transformed to triangle F prime G prime H prime in two steps? On a coordinate plane, triangle F G H has points (negative 2, 1), (negative 3, 3), (0, 1). Triangle F prime G prime H prime has points (negative 8, negative 4), (negative 12, negative 12), (0, negative 4). Which identifies the transformation that occurred after the dilation? a dilation by a scale factor of 3 and then a reflection across the x-axis a dilation by a scale factor of 3 and then a 180 degrees rotation about the origin a dilation by a scale factor of 4 and then a reflection across the x-axis a dilation by a scale factor of 4 and then a 180 degrees rotation about the origin
Answer:
A dilation by a scale factor of 4 and then a reflection across the x-axisExplanation:
1. Vertices of triangle FGH:
F: (-2,1)G: (-3,3)H: (0,1)2. Vertices of triangle F'G'H':
F': (-8,-4)G': (-12,-12)H': (0, -4)3. Solution:
Look at the coordinates of the point H and H': to transform (0,1) to (0,-4) you can muliply each coordinate by 4 and then change the y-coordinate from 4 to -4. That is a dilation by a scale factor of 4 and a reflection across the x-axis. This is the proof:
Rule for a dilation by a scale factor of 4: (x,y) → 4(x,y)(0,1) → 4(0,1) = (0,4)
Rule for a reflection across the x-axis:{ (x,y) → (x, -y)(0,4) → (0,-4)
Verfiy the transformations of the other vertices with the same rule:
Dilation by a scale factor of 4: multiply each coordinate by 44(-2,1) → (-8,4)
4(-3,3) → (-12,12)
Relfection across the x-axis: keep the x-coordinate and negate the y-coordinate(-8,4) → (-8,-4) ⇒ F'
(-12,12) → (-12,-12) ⇒ G'
Therefore, the three points follow the rules for a dilation by a scale factor of 4 and then a reflection across the x-axis.
Answer:a dilation by a scale factor of 4 and then a reflection across the x-axis

If 300% of 0.18 is equivalent to 20% of b, then b is equivalent to what number?
To calculate the value of b, we equate 300% of 0.18 to 20% of b, convert percentages to decimals, and solve for b, resulting in b being 2.7.
Explanation:To find the value of b when 300% of 0.18 is equivalent to 20% of b, we can set up the equation as follows:
300% × 0.18 = 20% × b
Converting percentages to decimal form gives:
3 × 0.18 = 0.2 × b
Now, we will multiply the numbers:
0.54 = 0.2b
To find the value of b, we divide both sides by 0.2:
b = \( \frac{0.54}{0.2} \)
b = 2.7
Therefore, the value of b is 2.7.

1 googol is 1 × 10100 Danesh says, " When I multiply 1.496 × 1011 by 6.68 × 109 I get nearly 1 googol because 1.496 × 1011 × 6.68 × 109 = 9.99 × 1099 " (b) Is Danesh correct? Give a reason for your answer
Danesh is incorrect as the multiplication of 1.496 × 1011 and 6.68 × 109 results in a value with 1020, not 1099. Moreover, 1 googol equals 1 × 10100, which is much larger.
Explanation:No, Danesh is incorrect. According to the laws of exponents, when you multiply two powers with the same base, you add the exponents. Therefore, the multiplication of 1.496 × 1011 and 6.68 × 109 will result in a value that is multiplied by 1020 and not 1099. Also, 1 googol is significantly larger than the result of this multiplication because it is equal to 1 × 10100. Thus, the statement made by Danesh is inaccurate.

Perform the indicated operation and write the result in the form a + bi.
4i(-i + 3) - 3(6 - 2i)
Answer:
- 14 + 18i
Step-by-step explanation:
Note that i² = ([tex]\sqrt{-1}[/tex] )² = - 1
Given
4i(- i + 3) - 3(6 - 21) ← distribute both parenthesis
= - 4i² + 12i - 18 + 6i
= - 4(- 1) - 18 + 18i
= 4 - 18 + 18i
= - 14 + 18i
The indicated operation of 4i(-i + 3) - 3(6 - 2i) in the form a + bi is -14 + 18i.
To perform the indicated operation and write the result in the form a + bi, we have to distribute and combine like terms carefully.
Starting with 4i(-i + 3), we distribute 4i:
4i * (-i) = -4i^2 = 4 (since i^2 = -1)
4i * 3 = 12i
This gives us 4 + 12i.
Now addressing the second part, -3(6 - 2i), we also distribute:
-3 * 6 = -18
-3 * (-2i) = 6i
This results in -18 + 6i.
Combining both parts (4 + 12i and -18 + 6i):
(4 + 12i) + (-18 + 6i) = (4 - 18) + (12i + 6i)
= -14 + 18i
