Answer:

Step-by-step explanation:

(3x - 4)/8 = (x + 2)/3       Cross multiply

8(x +2) = 3(3x - 4)          Remove the brackets using the distributive  property

16x + 16 = 9x - 12          Subtract 16 from both sides

16x = 9x - 12 - 16           Combine

16x = 9x - 28                 Subtract 9x from both sides

16x - 9x = - 28               Combine

7x = - 28                         Divide by 7

x = - 4

Answer:

2.203

Step-by-step explanation:

Subtract 7/10 from both sides of the equation

2.903 = [tex]y[/tex] + 7/10

2.903 - 7/10 = y + 7/10 - 7/10

Mai runs 3 laps around the track in 4 minutes.
a. How many minutes per lap is that?
b. How many laps per minute is that?
C. . If Mai runs 21 laps at the
same rate, how long does it
take her?
Explain your reasoning

Answers

The total distance Mai runs is 400(4), so the distance equals 1,600 meters. If it takes her 250 meters per minutes, then if you divide 250 with 1600– it’ll take her 6.4 minutes

A car can drive 415 miles on 10 gallons of gasoline. What is the car’s mileage for 1 gallon of gas?

Answers

Answer:

41.5

Step-by-step explanation:

Answer:

41.5 miles per gallon

Step-by-step explanation:

Since you are finding the miles per gallon, you should do 415 and 10 both divided by 10 to find the number of miles for one gallon. 415 divided by 10 is 41.5, while 10 divided by 10 is 1, so for one gallon, the car can drive 41.5 miles, or 41.5 miles per gallon.

In the given figure, find the measure of angle BOC, angle COD and angle DOE ?​

Answers

Answer:

Step-by-step explanation:

[tex]2x - 10^o + 2x + 30^o + x + 10^o + 50^o = 180^o \\\ 5x + 80^o = 180^o \\\ 5x = 180^o - 80^o \\\ 5x = 100^o \\\ x = \frac{100^o}{5} \\\\ x = 20°[/tex]

I hope I've helped you.

Explanation:-

From the given figure :

∠AOB = 50°

∠BOC = x+10°

∠COD = 2x+30°

∠DOE = 2x-10°

We know that

The sum of the angles lie on the same line = 180°

⇛ ∠AOB + ∠BOC + ∠COD + ∠DOE = 180°

⇛ 50°+x+10°+2x+30°+2x-10° = 180°

⇛ 5x+80° = 180°

⇛ 5x = 180°-80°

⇛ 5x = 100°

⇛ x = 100°/5

⇛ x = 20°

∴ x = 20°

Now,

The measure of ∠BOC = x+10°

= 20°+10°

= 30°

The measure of ∠COD = 2x+30°

= 2(20°)+30°

= 40°+30°

= 70°

The measure of ∠DOE = 2x-10°

=2(20°)-10°

= 40°-10°

= 30°

Answer:-

The measure of ∠BOC = 30°

The measure of ∠COD = 70°

The measure of ∠DOE = 30°

Remember:-The sum of the angles lie on the same line is 180°

The total amount of money that Kevin gave over 20 years period was twice the total amount of money that Billy gave. calculate the value of A. ​

Answers

The value of A is RM 205.

Since Billy gave money to a charity over a 20 year period, from Year 1 to Year 20 inclusive, and he gave RM150 in Year 1, RM160 in Year 2, RM170 in year 3, and so on, and Kevin also gave money to the charity over the same 20 years period, but he gave RMA im Year 1 and the amount of money he gave each year increased, forming an arithmetic sequence with common difference RM30, and the total amount of money that Kevin gave over 20 years period was twice the total amount of money that Billy gave, to calculate the value of A the following calculation must be performed:

Billy = (150 x 20) + 10 + 20 + 30 + 40 + 50 + 60 + 70 + 80 + 90 + 100 + 110 + 120 + 130 + 140 + 150 + 160 + 170 + 180 + 190 Billy = (150 x 20) + 1900 Billy = 3000 + 1900 Billy = 4900 Kevin = (9800 - (30 + 60 + 90 + 120 + 150 + 180 + 210 + 240 + 270 + 300 + 330 + 360 + 390 + 420 + 450 + 480 + 510 + 540 + 570)) / 20 Kevin = (9800 - 5700) / 20 Kevin = 4100/20 Kevin = 205

Hannah wants to buy cupcakes and cookies for her friends with a budget of $35. Cupcakes are $6
and cookies are $1.

1. What is the maximum amount of
cupcakes she can buy?

2. if she buys the maxium amount of cupcakes, how many cookies will she be able to buy?

Answers

1. She can buy 5 cupcakes and spend 30 dollars.
2. So she can by 5 more cookies with the rest of her money.

1. Since Hannah cannot buy a fraction of a cupcake, the maximum number of cupcakes she can buy is 5.

2. If Hannah buys the maximum amount of cupcakes (5 cupcakes), she will be able to buy 5 cookies with the remaining budget.

To find the maximum number of cupcakes Hannah can buy, we need to divide her budget by the cost of each cupcake:

1. Maximum cupcakes she can buy:

Maximum cupcakes = Budget / Cost per cupcake

Maximum cupcakes = $35 / $6 ≈ 5.83 (rounded down to the nearest whole number, as you cannot buy a fraction of a cupcake)

Since Hannah cannot buy a fraction of a cupcake, the maximum number of cupcakes she can buy is 5.

2. If she buys the maximum amount of cupcakes (5 cupcakes), we can find out how many cookies she can buy with the remaining budget.

Remaining budget after buying cupcakes:

Remaining budget = Total budget - (Number of cupcakes * Cost per cupcake)

Remaining budget = $35 - (5 * $6)

Remaining budget = $35 - $30

Remaining budget = $5

Now, we can calculate the number of cookies she can buy with the remaining budget:

Number of cookies = Remaining budget / Cost per cookie

Number of cookies = $5 / $1 = 5

Hence, if Hannah buys the maximum amount of cupcakes (5 cupcakes), she will be able to buy 5 cookies with the remaining budget.

Step-by-step explanation:

brainliest pls

$15 is the normal cost for a single player.

Given that a game costs $132 for 12 people. That's $4 less per person than the normal cost for a single player.

We need to find the normal cost for a single player,

Let's denote the normal cost for a single player as "x" dollars.

According to the information given, the Light Storm group package costs $132 for 12 people, which means each person in the group pays $132 / 12 = $11.

We also know that the group package cost per person is $4 less than the normal cost for a single player. So, we can set up the following equation:

x - 4 = 11

Solving for "x":

x = 11 + 4

x = 15

Therefore, the normal cost for a single player is $15.

the mean is 100. One individual score is at the 20th percentile and has a raw score of 85. What is the standard deviation

Answers

Answer:

Look at it this way. About two-thirds of the populace are thought to possess IQs between 85 and 115, which is to say, more or less average. That leaves about one sixth of the populace significantly below average and one sixth significantly above average.

Why such a large range for average — there’s a 30-point gap between 85 and 115? That’s because IQ tests measure only certain kinds of intelligence, and people who might be weak in some areas might be strong in other areas. Consider the difference between being book-smart and being street-smart. A person who is book-smart would be expected to score well on an IQ test but might not fare so well in a dangerous neighborhood after dark. A person who is street-smart would know better than to visit that neighborhood after dark but might not score so well on an IQ test.

Step-by-step explanation:

Answer:

Step-by-step explanation:

To calculate the value of the standard deviation in this equation, we must use Z-scores, therefore we are assuming that the distribution is regular.

At the twentieth percentile of a regular distribution, the z-score is -2.88. Using this information we can reverse-engineer the z-score calculation equation, [tex]z=\frac{n - x'}{s_{x} }[/tex]. x' being the mean of 100, n being the value of 85, z being the z score of -2.88 and s base x being the standard deviation.

[tex]-2.88=\frac{85-100}{s_{x}}[/tex].

The standard deviation is equivalent to 5.2083

Answers

62 people like coffee or tea, or both

A survey of 70 people found that 50 like coffee, 25 like tea, and 13 like both.

The amount of people that like only coffee = 50 - 13 = 37

The amount of people that like only tea = 25 - 13 = 12

The amount of people that like neither = 70 - (37 + 12 + 13) = 8

The amount of people who like coffee or tea, or both = 37 + 12 + 13 = 62

Answer:

13 like both

12 like tea

37 like coffee

62 people like coffee, tea or both

8 don't like neither of them

Step-by-step explanation:

let us remember that 25 people like tea but 13 of them like both. And 50 people like coffee but 13 like both.

so:

25-13=12

12 equals to the number of people that only like tea.

50-13=37

37 equals to the number of people that only like coffee.

If you add the 13 (that like both) + 12 (that like tea) + 37 (that like coffee) that equals to 62 people that like coffee or tea, or both.

13+12+37=62

62 equals to the number of people that like coffee or tea, or both

So that means that 8 people don't like either coffee or tea.
