Whats 30 times 30 plus 45 minus 456

Answers

30 times 30 plus 45 minus 456 is 489

Answer:

489 or -113

Step-by-step explanation:

Whats 30 times 30 plus 45 minus 456

rewrite in terms of numbers:

30 * 30 + 45 - 456

remember the order of operations and solve:

30 * 30 + 45 - 456

=900 + 45 -456

= 945 - 456

= 489

the answer could change depending on the placement of parenthesis, such as if the equation was:

30 * (30 + 45 -456)

solve with the order of operations:

30 * ( 30 + 45 - 456)

= 30 * (75 - 456)

= 30 *(-381)

= -11430

Write a formula expressing the dependence of the variable s on t, where s is the distance between the bicyclist and the station in km, t - the duration (time) of his travel in hours. Using the formula, find: s for t=3.5

Answers

Part a:
for t = 3.5 hours
velocity = distance / time
distance = velocity x time
distance = 12 x 3.5 = 42 km

Part b:
for s = 30 km
velocity = distance / time

How do the angle measures and side lengths compare in similar figures ?

Answers

Answer:

Matching sides of two or more polygons are called corresponding sides, and matching angles are called corresponding angles. If two figures are similar, then the measures of the corresponding angles are equal and the ratios of the lengths of the corresponding sides are proportional.

Step-by-step explanation:

The angles are congruent in a similar figure and the ratio of the sides is in proportion.

What are similar figures?

Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent, and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor.

Given: Two figures are similar for example say two triangles are similar then Similar triangles are triangles that have the same shape, but their sizes may vary. All equilateral triangles, squares of any side lengths are examples of similar objects. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion. We denote the similarity of triangles here by ‘~’ symbol.

Hence, The angles are congruent in a similar figure and the ratio of the sides is in proportion.

Answer:

Width also known as (W) = 1.5 meters

Area also known as (A) = 6 square meters

Length also known as (L) = ?

the formula to find Length is:

Step-by-step explanation:

[tex]L=\frac{A}{W}[/tex]

[tex]L = \frac{6}{1.5}[/tex]

[tex]L= 4 m[/tex]

Choice 3 is the answer

1.5x = 6

x=4

substitute 4 for the x

1.5(4)=6

1.5×4 = 6

so

6=6

so the answer is

1.5x=6

x=4

The answer would be 4.

If you multiply 1.5 by 4 you get 6.0 and it's the same to 6.

Which values are in the solution set of the inequality -9/4x+12≥-8? Select all that apply. A. 6 B. 7 C. 8 D. 10 E. 11

Answers

Answer: A, B, C

Step-by-step explanation:

To solve for the inequality, we would solve it as if it had an equals sign.

[tex]-\frac{9}{4} x+12\geq -8[/tex]             [subtract both sides by 12]

[tex]-\frac{9}{4} x\geq -20[/tex]                   [multiply both sides by -4/9, remember to flip inequality]

[tex]x\leq \frac{80}{9}[/tex]

Now, we know that the solution is less than or equal to 80/9, which is approximately 8.89.

Looking at the answer choices, A, B and C are the answers since they are both less than 8.89.

Tonya plans to join a fitness club. She researched the costs to join different clubs in her area and found that there is a linear relationship between the total cost of belonging to a club and the number of months that you are a member. Each club charges monthly dues, and some clubs require new members to also pay a one-time membership fee. The total costs of being a member for 6 months, 12 months, and 24 months at each of three clubs are shown in the table.

Total Cost of Fitness Club Membership
Length of membership
Club 1
Club 2
Club 3
6 months
$108
$120
$126
12 months
$216
$210
$252
24 months
$432
$390
$504

How many of the clubs require new members to pay a one-time membership fee?
A: 0
B: 1
C: 2
D: 3

Answers

b because it’s the only one that doesn’t double in value

The number of clubs that require new members to pay a one-time fee is one.

In order to determine which fitness club requires a one-time membership fee, the average cost per month for each club has to be determined.

Cost of membership per month = cost / number of months

Average cost of Club 1

Average cost for 6 months = $108/6 = $18

Average cost for 12 months = $216 / 12 = $18

Average cost for 24 months = $432 / 24 = $18

The average costs each month is the same. This means that there is no one-time membership fee in this club.

Average cost of Club 2

Average cost for 6 months = 120 / 6 = $20

Average cost for 12 months = $210 / 12 = $17.50

Average cost for 24 months = $390 / 24 = $16.25

The average costs each month is not the same. This means that there is a one-time membership fee in this club.

Average cost of Club 3

Average cost for 6 months = $126 / 6 = $21

Average cost for 12 months = $252 / 12 = $21

Average cost for 24 months = $504 / 24 = $21

The average costs each month is the same. This means that there is no one-time membership fee in this club.

Which statement is false? A All whole numbers are integers. B All integers greater than 0 are whole numbers. C No real numbers are irrational numbers. D No integers are irrational numbers.

Answers

no real numbers are irrational numbers

It is false that C. No real numbers are irrational numbers

Real numbers include both irrational and rational numbers so it is not true that a real number cannot be a rational number.

The other options are wrong because:

All whole numbers are indeed integers because integers are numbers that do not have to be written as fractions which makes them whole. All integers greater than 0 are whole numbers because they do not need to be written as fractions. Because integers are whole numbers, they cannot be irrational numbers which are numbers that go on forever e.g. π. Integers are whole which means that they can be completed.

Conclusively speaking therefore, the only false statement here is that no real numbers are irrational numbers.
