for a class gardening project 1/3 of mrs gordon's students planted marigolds and 1/2 planted tulips what fraction of the class planted either marigolds or tulips

Answers

Get them to have a common denominator so you can add them
(1/3)×2= 2/6 and (1/2)×3= 3/6
Add them together
(2/6)+ (3/6)= 5/6
So 5/6 of the class planted either marigolds or tulips and 1/6 of the class planted neither

Ciara brought $240 to spend on gifts for her family. She found 8 identical statues at a gift shop. She had $72 leftover. How much did each statue cost?

Answers

Hello! In order to solve this problem, first, you have to subtract the 72 dollars she didn’t spend on statues from 240. 240 - 72 = 168. That’s $168 she spent on statues. She bought 8 of them. Now, divide the total cost by 8. 168/8 = 21. There. Each statue Ciara bought costed $21.

what does it mean to solve the system of equation?

Answers

Solving a system of equations usually means that you solve for a variable in a specific equation. Systems of equations consist of 2+ equations that contain the same variables.

Ex :

2x + 2y = 8
3x + 3y = 9

Then, using those equations, you solve for x & y

06.01) Saturday morning there were 7 adults and 20 kids at Pump and Jump Land. The morning cash registers show $236 was collected. In the afternoon there were 21 adults and 50 kids for a total amount of $618. What is the cost for 1 adult?

Answers

The cost of 1 adult for the given games using the various parameters to create a simultaneous equation gives; $8

How to create simultaneous equations?

Let cost of adults be x and let cost of kids be y.

Now, there were 7 adults and 20 kids at Pump and Jump Land and the cash collected was $236. Thus, we can say that;

7x + 20y = 236 -----(1)

Similarly, there were 21 adults and 50 kids for a total amount of $618. Thus;

21x + 50y = 618 -----(2)

Solving both equations simultaneously gives;

x = $8 and y = $9

Thus, cost of 1 adult = $8

Dominique used the inequality below to find the maximum number of sweatshirts she could purchase with her savings.

32 x < 300

What is the greatest number of sweatshirts Dominique can purchase?

Answers

We just have to find the closest number that can be multiplied by 32 and still be under 300. Do this by following this step:

Divide by 32 on both sides.

x < 9.375

We can't buy 9.375 sweatshirts though, and we can't add more decimals or it will go over 300, so you round down to 9.

Dominique can buy 9 sweatshirts without going over $300!

What is 10.49 seconds rounded to the nearest second

Answers

10 seconds... You just have to leave the first two numbers before the point. :) If a number is bigger after the point like for example 10.59 the answer would be 11 because it can be rounded by the 5. :)

Given 10.49 seconds to be rounded to the nearest second, we would round down 10.49 seconds to have: 10 seconds.

Recall:

When rounding a number, if the number that comes before it is 5, 6 and up to 9, you round the number up. i.e. 57 to the nearest ten would be rounded up to 60.

When rounding a number, if the number that comes before it is from 4 below, you round the number down. i.e. 54 to the nearest ten is 50.

Thus:

Given 10.49 seconds, we want to round the number to the nearest second.

We need to round it down.

Therefore:

10.49 to nearest seconds = 10 secs.

In summary, given 10.49 seconds to be rounded to the nearest second, we would round down 10.49 seconds to have: 10 seconds.

The football team lost 4 yards on 2 plays in a row. Which of the following could represent the change in field position?

Answers

Lost (⬅key word) 4 is equal to -4
On 2 plays that is times 2
So all together is -4×2
A negative times a positive is negative
-4×2= -8
Hope this helped you☺

Final answer:

The football team lost 4 yards on 2 plays in a row, resulting in a change in field position of -8 yards.

Explanation:

The football team lost 4 yards on 2 plays in a row. To determine the change in field position, we need to subtract the total yardage lost from the starting field position. Assuming the starting field position was at the 50-yard line, the change in field position would be -4 yards x 2 plays = -8 yards. Since the team lost yardage, the change in field position would be a negative value.

−13π/5 find the reference angle

Answers

I would convert to degrees first seems to make it easier.

252 is in the 3rd quadrant so 180 is the closest angle on the x-axis
ref angle = 252 - 180 = 72

write a linear equation that is parallel to 12x+3y=24 and passes through the point (-2,7)

Answers

In order to write the formula for another line which is parallel, we need the slope (m). Parallel lines never in fact touch or intersect at any one point. They are either the same lines, occupying the same points, or different parallel lines, never occupying the same points, but sharing the same slope (m).
If we put out equation in slope-intercept format: y = mx+b, we can obtain our needed m.
12x+3y=24 ->> 3y = -12x+24
3y/3 = (-12x+24)/3 ->> y = -4x+8, therefore our m = -4
Now we can use our info to make the line in point-slope format: y-y1 = m (x-x1)
So, y-7 = -4 (x--2) or y-7 = -4 (x+2)
You can leave it like that or convert it:
y-7 = -4x -8 ->> y = -4x -8+7 ->> y = -4x-1
or even in this format: 4x+y=-1

find an equivalent expression to 3 (4m-2)-2(m+5). write your answer as an expression with two terms

Answers

12m-6-2m+10 (10m+4) is the simplest it can go

Answer:

10m - 16

Step-by-step explanation:

3 (4m-2) -2(m+5)

The equivalent expression can be simplified as an expression with two terms as follows:

3 (4m-2) -2(m+5)

Open each parenthesis by multiplying the outside value with the values in the parenthesis.

3 (4m-2) = 12m - 6

-2(m + 5) = -2m -10

Bring the value together

12m - 6 -2m - 10

collecting like terms

12m -2m - 6 - 10

10m - 16

Evaluate 3x + y when x = 1/3 and y = -7/4

Write the answer in simplest form

Answers

Given:
3x + y
Substitute the variables for x = 1/3 and y = -7/4:
3 · 1/3 + -7/4
Multiply 3 by 1/3:
1 + -7/4
Add -7/4 to 1:
-3/4

Final answer:

The expression 3x + y simplifies to -3/4 when x equals 1/3 and y equals -7/4.

Explanation:

To evaluate the expression 3x + y when x = 1/3 and y = -7/4, we simply substitute these values into the expression.

So 3x + y becomes 3*(1/3) - 7/4, which simplifies to 1 - 7/4.

To simplify this further, we convert 1 (which is the same as 4/4) and -7/4 to have the same denominator (which is 4). So, 4/4 - 7/4 equals -3/4.

So, the simplest form of 3x + y when x = 1/3 and y = -7/4 is -3/4.

Jan has 10 dolls. Kat has 7 dolls. choose yes or no to show if the equation can be used to find how many fewer dolls Kat has than Jan.
10-7=3 yes or no

3+7=10 yes or no

10+7=17 yes or no

7+3=10 yes or no

Answers

The answer is 10-7. The reason is that if Jan has 10 and she has 7, they want to know fewer which means less than as subtracting. So basically you would do 10-7 and that is 3. Also you can tell by the question that its 10-7. Hope it helps!
