Simplify the expression
7u2–9+2u+10+5u+5

Answer:

D. None.

Step-by-step explanation:

Say the obtuse angle is 100 degrees. Since the sum of all angles in a triangle cannot be bigger than 180, it's not possible because 195 (100+95) is greater than 180 degrees. Hope this helps.

Step-by-step explanation:

Answer:

3

Step-by-step explanation:

The slope of this line is $5. This means Andre is saving $5 per week in bank.

The general equation of a straight line is -

y = mx + c

Where -

[m] is the slope of the line.

[c] is the y - intercept.

Given is a graph showing savings in Andre’s bank account.

The coordinates through which the line passes are -  (0, 40) and (4, 60)

Then the slope of this line will be -

m = (60 - 40)/(4 - 0) = 20/4 = 5

A slope of $5 means that Andre is saving $5 per week at bank.

Therefore, the slope of this line is $5. This means Andre is saving $5 per week in bank.

2*9+4*7

Answer: The correct answer would be "2 x 9 + 4 x 7"

Step-by-step explanation:

The "sum" which is the plus sign in between 4 and 9 where you add the products

The sum of the "products of 2 and 9" would be 2 x 9

and product of four and seven would be 4 x 7

Answer:

➡7pieces

Step-by-step explanation:

Let's suppose that x = the number of ropes that can be cut.

➡[tex]X = 11\frac{1}{2} ÷ 1\frac{1}{2}[/tex]

➡[tex]X = 11.5 ÷ 11.5[/tex]

➡[tex]X \approx 7.66[/tex]

➡[tex]X = \bf 7pieces[/tex]

Answer:

22ft^3

Step-by-step explanation:

Find the volume of one wooden cube block. Each of the edge length is 1/2

Volume of cube = l x w x h

l = 1/2      w = 1/2       h = 1/2

1/2 x 1/2 x 1/2 = 1/8

Then find the volume of the total box with how much total wooden blocks there are.

They are 176 wooden blocks.

Volume of one wooden cube block x the total number of wooden cube blocks = total volume of box.

So you do 1/8 x 176 and with that, the volume is 22ft^3.

Answer:

64 units

Step-by-step explanation:

Hello! This is a proportion problem

52 is a smaller proportion to 78.

X is a smaller proportion to 96.

Since this both have the same ratio scale, we can set them equal to each other, remembering to put the smaller number from each one on the top.

(52/78)=(x/96)

Now we can just solve for X:

(96*52)/(78) = 64 = X

Our answer is in feet so 64 feet is the distance between the lions and the monkeys.

Answer:

C). 10

Step-by-step explanation:

Using the Pythagorean theorem, a^2+b^2=c^2

We know the two sides (a and b) and are trying to find the hypotenuse (c).

Substitute the known values:

7^2+7^2=c^2

Simplify and solve:

49+49=c^2

98=c^2

sqrt(98)=c

c=9.899

Rounded to the nearest whole number would be 10

Answer:

0 pounds

Step-by-step explanation:

Carrie buys 7/8 pound of red apples and 15/16 pound of green apples.

Which answer is the most accurate estimate for how many more pounds of green apples she buys than pounds of red apples?

Total number of green apples - Total number of red apples

Our expression: [tex]\frac{15}{16}-\frac{7}{8}[/tex]

[tex]\frac{15}{16}-\frac{7}{8} \\\\\frac{15}{16}-\frac{14}{16} \\\\\frac{1}{16}[/tex]

Since [tex]\frac{1}{16}[/tex] is not a full pound (1 pound), our answer will be 0 pounds.

Answer:

clouds

Step-by-step explanation:

Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies with larger diurnal temperature changes due to greater radiation at night and greater sunshine during the day.

I observe that when moving closer to station B the elevation as well as how close it is to the clouds is making the pressure more/less. also there could be more clouds there making the pressure more high or low.

Areas where the air is warmed often have lower pressure because the warm air rises. These areas are called low pressure systems. ... A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere where they meet.

How to solve:

We need to create a table for Donovan's height, compare it to Margaret's table, and then choose the appropriate statement. H will represent height, and a will represent age. B and c are constant values, and x is a coefficient to a-c

Simplifying equation

Set up equation                                                 H = 105 + 4.25(a - 5)

Distribute                                                            H = 105 + (4.25a - 21.25)

Age 5

Set up equation                                                 H = 105 + (4.25a - 21.25)

Substitute                                                           H = 105 + [(4.25*5) - 21.25]

Simplify                                                               H = 105 + (21.25 - 21.25)

Simplify                                                               H = 105

Age 6

Set up equation                                                  H = 105 + (4.25a - 21.25)

Substitute                                                            H = 105 + [(4.25*6) - 21.25]

Simplify                                                                H = 105 + (25.5 - 21.25 )

Subtract                                                               H = 105 + 4.25

Solve                                                                    H = 109.25

Age 7

Set up equation                                                  H = 105 + (4.25a - 21.25)

Substitute                                                            H = 105 + [(4.25*7) - 21.25]

Simplify                                                                H = 105 + (29.75 - 21.25)

Subtract                                                               H = 105 + 8.5

Solve                                                                    H = 113.5

Continue for the following ages (8-10)

1. Create a table for both sets of data. Example:

______________________________________________

Age                       |   5   |      6     |    7   |     8     |   9   |     10     |

Mar. height (cm)  | 101  |    105   |  109  |   113    |  117  |    121     |

Don. height (cm) | 105 | 109.25 | 113.5 | 117.75 | 122 | 126. 25 |

______________________________________________

2. Find which statement applies

    2a. Margaret did not grow faster than Donovan

    2b. Donovan did grow faster than Margaret

    2c. Margaret and Donovan did not grow at the same rate

    2d. There is enough data to draw a conclusion

Check:

We came to this conclusion by putting Donovan's data into a chart. We can check by writing an equation for Margaret's height. Then, use that equation with Donovan's to see the difference

Margaret's equation:

H = 4a + 81

Comparison (using ages 8 & 9):

8:

H= 4a + 81       |       H = 105 + (4.25a - 21.25)

H = (4*8) + 81   |       H = 105 + [(4.25*8) - 21.25)

H = 32 + 81      |       H = 105 + 12.75

H = 113             |       H = 117.75

9:

H = 117              |      H = 122

________________________

113 < 117.75

117 < 122

Because the statement still holds true, answer B is correct.

Answer :D

x = 52

Question explanation:

1. Add 28 to both sides:

[tex]5x - 28 = 232[/tex]

[tex]5x - 28 + 28 = 232 + 28[/tex]

2. Simplify:

[tex](adding, add again) = 5x =260[/tex]

3. Divide both sides by the same factor

[tex]5x = 260[/tex]

[tex]\frac{5x}{5} = \frac{260}{5}[/tex]

4. Cancel terms that are in both the numerator and denominator.

5. Divide the numbers.

Step-by-step explanation:

Answer:

4: 321.5cm²

5: Length of fencing = 62.46cm, Area of Yard: 232cm²

6: Area of 1 sign: 3950cm². Paint cans needed: 237

Step-by-step explanation:

4:

Area of Machine = Area of Square - 1/4 Area of Circle taken away

Area of Machine = (20x20) - 1/4(π10²)

Area of Machine = 400 - 1/4(3.14 x 100)

Area of Machine = 400 - 1/4(314)

Area of Machine = 400 - 78.5 = 321.5cm²

5: The perimeter of this figure is the length of fencing needed. The area of the yard can be figured out:

Perimeter: We're missing one side. So what we need to see here, is that the figure has a hidden triangle. Do you see it? its a missing right angle triangle, and we can use the Pythagorean theorem to find the hypotenuse, which is the missing side:

a² + b² = c²

16² + 7² = c²

256 + 49 = c²

305 = c²

c ≅ 17.46cm

now that we know the last dimension of the trapezoid, the Perimeter is known to be 11 + 16 + 18 + 17.46 = 62.46cm

Area = 1/2(b1+b2) x h

Area = 1/2(11 + 18) x 16

Area = 14.5 x 16 = 232cm²

6:

Area of 1 Sign = Area of rectangle + Area of Triangle

Area of 1 Sign = (90x30) + 1/2(50 x 50)

Area of 1 Sign = 2700 + 25x50

Area of 1 Sign = 2700 + 1250 = 3950cm²

.: area of 6 signs will be 6 x 3950 = 23,700cm²

If one can of paint covers 1 squared meter, then it covers 100 squares cm. So it will take 23700/100 = 237 paint cans to cover all 6 signs :)

Hope this helped!
