The cafeteria director at Great Minds School wants to know what percent of the students would choose vegetarian entrees if they were available. Which of the following survey methods will allow the director to make a valid conclusion about the percentage of students who would choose vegetarian entrees?

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.

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.

Given that [tex]a_1=-15[/tex] and [tex]a_{n+1}=a_n-8[/tex]

So each of the successive term of the given sequence is decreases by 8

Therefore the common difference is -8

The given sequence is a arithmetic sequence.

The general form is [tex]a_n=a_1+(n-1)d[/tex]

Substitute [tex]a_1=-15[/tex] and d=-8 in [tex]a_n=a_1+(n-1)d[/tex] we get

[tex]a_n=-15+(n-1)(-8)[/tex]

[tex]=-15-8n+8[/tex]

Step-by-step explanation:

 -3.4+(-y)- -5/8

Note: (1) + × - = -

2) - × - = +

3) - × + = -

Therefore

 -3.4+(-y)- -5/8

= -3.4 - y + 5/8

-3.4 - y + 0.625

Collect like terms

0.625 - 3.4 - y

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.

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.

In the given image, you can observe we have two right triangles.

Also, we know by given that those triangles are similar, which means their sides are proportional and their angles are congruent.

If the triangles are similar, we can define the following proportion between sides.

[tex]\frac{4}{a} =\frac{3}{6}\\ 24=3a\\a=\frac{24}{3}\\ a=8[/tex]

Now we use the Pythagorean's Theorem to find each hypothenuse.

Answer: 2/5>1/3

Step-by-step explanation: To make this easier, convert both to fifteenths.

To do this for 2/5, divide 15 by 5 to get 3. Now multiply both 2 and 5 by 3. This should get you 6/15.

To convert 1/3, divide 15 by 3 to get 5. Now multiply both 1 and 3 by 5. This should get you 5/15.

6/15>5/15 so 2/5>1/3.

Answer:

63/10 = 6 3/10 miles

Step-by-step explanation

There are 63/10 or 6 3/10 or 6.3 miles Dasha runs 9 laps around the lake if one lap around the lake is 7/10 miles.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

One lap around the lake is 7/10 miles.

Let x be the number of miles in 9 laps

x = 9(7/10)

x = 63/10 miles

Or

x = 6.3 miles

Thus, there are 63/10 or 6 3/10 or 6.3 miles Dasha runs 9 laps around the lake if one lap around the lake is 7/10 miles.

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.

Answer:

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.

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.

Option B: [tex](x, y) \rightarrow(x+5, y+3)[/tex] is the rule for the translation

Explanation:

The coordinates of A,B,C are [tex](-3,2)[/tex] ,[tex](-3,-3)[/tex] , [tex](0,-2)[/tex]

The coordinates of A',B',C' are [tex](2,5)[/tex] , [tex](2,0)[/tex] , [tex](5,1)[/tex]

We need to determine the rule for the translation

The rule for the translation is given by

[tex]P(x, y) \rightarrow P^{\prime}(x+a, y+b)[/tex]

Let us determine the translation from A to A'

[tex]A(-3,2)\rightarrow A^{\prime}(-3+a, 2+b)\rightarrow A'(2,5)[/tex]

Thus, we have,

[tex]\begin{aligned}-3+a &=2 \\a &=5\end{aligned}[/tex]   and   [tex]\begin{array}{r}2+b=5 \\b=3\end{array}[/tex]

Thus, the rule is given by

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 :

The 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

1. Vertices of triangle FGH:

2. Vertices of triangle F'G'H':

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:

       (0,1) → 4(0,1) = (0,4)

        (0,4) → (0,-4)

Verfiy the transformations of the other vertices with the same rule:

       4(-2,1) → (-8,4)

       4(-3,3) → (-12,12)

        (-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.

The best choice is to use a calculator (the button is [tex]\sqrt[/tex]), but if that is not an option here are a few tips.

If a perfect square ends with a 1, then the last digit of its square root has to be either 1 or 9.

If a perfect square ends with a 4, then the last digit of its square root has to be either 2 or 8.

If a perfect square ends with a 5, then the last  digit of its square root is definitely 5.

If a perfect square ends with a 6, then the last digit of its square root has to be either 4 or 6.

If a perfect square ends with a 9, then the last digit of its square root has to be either 3 or 7.

I took a look and all of them seem to be perfect squares so hopefully this helps!
