After tax, the total is $45.99. What percentage of the total is the subtotal?

Answer:

60ft

Step-by-step explanation:

Using the formula shown a^2 + b^2 = c^2

5 ^2 + 12^2 = c^2

25 + 144 = c^2

169 = c^2

Take the square root of both sides:

C = 13

Step-by-step explanation:

10+60t≤280

60t≤280-10

60t≤270

6t≤27

2t≤9

t≤9/2

t≤4.5

t=4 hours

first subtract $10 from$280 and you get $270

270 divided by 60 = 4.5

so the answer is four and a half hours

Answer:

y=-x

Step-by-step explanation:

Since the y-axis and x-axis are intersecting lines then you need to apply the locus of intersecting lines which would be the angle bisector and since the problem is asking for the opposite signs you need to make it -x instead of x.

Hope this helps

Answer:

r = -11

Step-by-step explanation:

slope formula: (y2-y1)/(x2-x1) = slope

(5-r)/(4-8) = -4

(5-r)/ -4 = -4

5-r = 16

-r = 11

r = -11

im not sure but i beleive this is how you do it.

you find the agreegable slope, and then multiply it by the y value.

hope this helps! :)

Answer:

Step-by-step explanation:

Because these two triangles are isoceles triangles, two angles are the same, which in this case would be 78. 78 times 2 would give us 156 for the right triangle, but since 180 - 156 does not equal 16, they are not similar nor congruent.

Answer:

The kind of ice cream the least number of students prefer is Strawberry ice cream.

Step-by-step explanation:

We convert all given values to decimal

Hiroshi found that:

a) For vanilla ice cream

3/5 of his class prefers vanilla ice cream

3/5 to decimal = 0.6

b) For Chocolate ice cream

26% prefers chocolate ice cream

26% to decimal = 0.26

c) For strawberry ice cream

0.14 prefers strawberry ice cream

0.14 = 0.14

Arranging the numbers in order from least to greatest, we have :

0.14, 0.26 , 0.6

The kind of ice cream the least number of students prefer is Strawberry ice cream.

Answer:

4p-n+2q-3m is equivalent to 8p-3n+4q-9m

The expression 4(2p+ q) - 3(n+3m) is equivalent to the given expression. which is the correct answer would be an option (C).

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

The expression is given in the question following:

8p - 3n + 4q - 9m

We have to determine the equivalent expression to the given expression

As per option (C), we have

⇒ 4(2p+ q) - 3(n+3m)

Apply the distributive property of multiplication,

⇒ 4 × 2p+ 4 × q  - 3 × n + 3 × m

⇒ 8p + 4q  - 3n + 3m

Rearrange the terms in the above expression,

⇒ 8p - 3n + 4q - 9m

So this expression is the same as the given expression.

Therefore, the expression 4(2p+ q) - 3(n+3m) is equivalent to the given expression.

Answer: 2/7

Step-by-step explanation:

You take the top numbers and multiply them and then take the bottom numbers and multiply them and then you simplify.

1/3 × 6/7 = 6/21 = 2/7

To multiply fractions we'll multiply numerator with the numerator and denominator with the denominator and simplify (1/3 × 6/7) = 6/21 = 2/7.

Fractions are written in p/q form,where q ≠ 0 as it would become undefined.Fractions are of two types one is proper fraction and another one is improper fraction.

A fraction is is the form of numerator divided by the denominator.

To multiply two or more fraction we simply have to multiply numerator with the numerator and denominator with the deominator to combine them into one fraction and then we simplify the combined fraction until both the numerator and the denominator has HCF of 1.

Given (1/3 × 6/7) which is,

= 6/21.

= 2/7.

Step-by-step explanation: Sample space is just any and all possible outcomes

The sample space of the given experiment is (R,G, Y, B, O). So option A is the correct one.

A sample space is a set of all the possible outcomes in a random experiment. It is usually denoted by the letter, S.

The subset of the sample space are events.

Given experiment is that you randomly choose a ball from a bag which consists of 5 balls.

Balls are 1 red (R), 1 green (G), 1 yellow (Y), 1 blue (B), and 1 orange (O).

Each ball is of different color.

When you randomly choose a ball, the chosen ball can be any of the colors given.

So sample space = (R,G, Y, B, O)

Hence the required sample space is (R,G, Y, B, O).

Full question:

Suppose SAT scores among students are normally distributed with a mean of 500 and a standard deviation of 100.

If a college says it admits only people with sat scores among the top 10%. how high a sat score does it take to be eligible?

Answer and explanation:

To find where SAT score of student falls in the test given mean and standard deviation of scores, we can calculate: x-500/100 where x is number of SAT score of students

A sat score in the top 10% region would have a score better than 90% of other SAT scores. Therefore 0.90 has a z score of 1.28

We use algebra to find the score to be eligible thus:

1.28=x-500/100

x-500=128

x=128+500

x=628

Therefore to be eligible, a student needs to score at least 628, and be in the top 10% of scores
