Answer:
-48 and -49
Step-by-step explanation:
n + n + 1 = -97
2n + 1 = -97
2n + 1 - 1 = -97 - 1
2n = -98
2n/2 = -98/2
n = -49
-49 + 1 = -48
-49, -48

Use the net to find the surface area of the regular pyramid.
Number only. NO UNITS!
Answer:
40 in.²
Step-by-step explanation:
First, you have to find the area of the triangle, which you then multiply by 4 (because there are 4 triangles):
A=1/2(bh)
A=1/2(3x4)
A=1/2(12)
A=6
6x4=24 in.²
Next, you have to find the area of the square:
A=bh
A=4x4
A=16
Now, add 24 and 16 together to get your answer of 40 in.².
How far did I travel to reach my destination on each day of my three-day Trip? a. On Day 1, after traveling 5/8 of the way to the first day's destination, I still had 15 miles left to go before reaching my first destination. b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination. c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.
Answer: 81 miles
Step-by-step explanation:
The total distance traveled on the three-day trip is: 81 miles.
How did we get the value?Denote the total distance of each day's journey by D1, D2, and D3, respectively. Then write equations based on the given identities:
a. (5/8)D1 + 15 = D1
(3/8)D1 = 15
D1 = 40 miles
So, the total distance traveled on Day 1 is 40 miles.
b. 18 + (2/5)D2 = D2
(3/5)D2 = 18
D2 = 30 miles
So, the total distance traveled on Day 2 is 30 miles.
c. (5/11)D3 + 6 = D3
(6/11)D3 = 6
D3 = 11 miles
So, the total distance traveled on Day 3 is 11 miles.
Therefore, the total distance traveled on the three-day trip is:
40 + 30 + 11 = 81 miles.

(100 POINTS IF RIGHT!!!!!)
Answer:
1/2
Step-by-step explanation:
If the fraction of the box of pancake mix that Merida uses on Friday is not given, it is difficult to determine the exact fraction that she used on Saturday. However, if we assume that the fraction of the box of pancake mix used on Friday is 1/2 (which is a common amount for a recipe that serves 4-6 people), then we can solve for the fraction used on Saturday.
On Friday, Merida used 1/2 of the box of pancake mix.
On Saturday, she used 1 times as much pancake mix as Friday, or 1/2 * 1 = 1/2 of the box of pancake mix.
Therefore, Merida used 1/2 of the box of pancake mix on Saturday.
Note that if the fraction used on Friday is different, the fraction used on Saturday will also be different.

Answer:
30.68 cm²
Step-by-step explanation:
Area of the shaded region
= Area of rectangle - Area of semicircle
Given,
Height (h) = 4.5 cm
Base (b) = 9 cm
Diameter (d) = 5 cm
Formula
Area of the rectangle = bh
Area of the rectangle
= 9 x 4.5
= 40.5 cm²
Formula
Radius (r) = d/2
r = 5/2
r = 2.5 cm
Formula
Area of the semicircle = πr²/2
Note
The value of π is 3.14
Area of the semicirlce
= (3.14 x 2.5²)/2
= (3.14 x 2.5 x 2.5)/2
= 19.625/2
= 9.8125 cm²
Area of the shaded region
= Area of rectangle - Area of semicircle
= 40.5 - 9.8125
= 30.6875 cm²
~ 30.68 cm² approximately
Give the measure of the angle that is complementary to the given angle. (Example 1)
Answer:
45
70
36
52
20
130
Step-by-step explanation:
complementary means it adds up to 90 degrees.
subtract that angle from 90 to get the complementary angle
supplementary angles add up to 180 degrees
subtract that angle from 180 to get the supplementary angle
Answer:
1) 45
2) 60
3) 36
4) 52
5) 20
6) 130
Step-by-step explanation:
In the first 3 questions, it's asking us for a complementary angle to the given angle. A complementary angle is when 2 angles add up to 90 degrees. So, we are given 45 degrees already, so we can subtract that from 90 to find it's complementary angle, which is also 45. Continue to subtract from 90 for the next 2 problems.
In questions 4-6, we are asked to find an angle that is supplementary. A supplementary angle is when 2 angles add up to 180 degrees. We are given an angle that measures 128 degrees, so subtract 180-128 to get 52 degrees. Continue subtracting from 180 for the next 2 problems.
Hope this helps! :)
When playing a board game, Leilani rolls a number cube twice to determine her next move. In her past 10 moves, she’s rolled two 5s once. How many times does she expect to again roll two 5s in her next 30 moves? Which statement compares this prediction to the theoretical probability of rolling two 5s.
Answer: Leilani has the probability of rolling two 5s three times on her next 30 moves.
Step-by-step explanation: If on average Leilani rolls once in 10, then we can predict that she will at least roll 3 in 30.
Whats the ansewr to this one?
Answer:
1/9
Step-by-step explanation:
You want the probability of rolling a sum of 5 when you roll two dice.
Sum of 5There are 4 outcomes that have a sum of 5 when rolling two dice:
(1, 4), (2, 3), (3, 2), (4, 1)
There are 36 total possible outcomes, so the probability of rolling a 5 is ...
P(5) = 4/36 = 1/9
The probability of rolling a sum of 5 is 1/9.

7th grade - Find the surface area of this trapezoidal prism. Please help ASAP I'll give brainliest!!!
Answer:
[tex]380 \text{ m}^2[/tex]
Step-by-step explanation:
To find the surface area of the trapezoidal pyramid, we can use the formula:
[tex]SA = 2(b) + (p \cdot d)[/tex],
where [tex]b[/tex] is the area of the base, [tex]p[/tex] is the perimeter of the base, and [tex]d[/tex] is the prism's depth.
First, we should find the area of the base using the area of a trapezoid formula.
[tex]A_\text{trap} = \dfrac{b_1 + b_2}{2} \cdot h[/tex]
[tex]b = \dfrac{15 + 5}{2} \cdot 7[/tex]
[tex]b = 10 \cdot 7[/tex]
[tex]b = 70 \text{ m}^2[/tex]
Now, we can plug the given dimensions along with the base area into the surface area formula.
[tex]SA = 2(b) + (p \cdot d)[/tex]
[tex]SA = 2(70) + ([15 + 10 + 5 + 10] \cdot 6)[/tex]
[tex]SA = 140 + (40 \cdot 6)[/tex]
[tex]SA = 140 + 240[/tex]
[tex]\boxed{SA = 380 \text{ m}^2}[/tex]

Answer:To write the number 0.0000149 in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10.
First, we move the decimal point to the right until there is only one non-zero digit to the left of the decimal point, which gives us:
1.49 × 10^-5
Since we moved the decimal point 5 places to the right, the exponent of 10 is negative 5.
Therefore, the scientific notation of 0.0000149 is 1.49 × 10^-5.
Step-by-step explanation:
Answer:
1.49×10^-5
Step-by-step explanation:
0.0000149=1.49×10^-5
it's to the power of -5 because it's a decimal number not a whole number

Responses
A 3939
B 1616
C 3737
D 1313
E 17
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16

Answer:
Answer for Number 1: 54 1/2
Answer for Number 4: $2.36
Step-by-step explanation:
Explanation for number 1:
1. length x width = area right? So area divided by length = width!
159 3/8 divided by 18 3/4 = 8 1/2
2. width + width + length + length = perimeter right? Now you know the
width, you can do...
8 1/2 + 8 1/2 + 18 3/4 + 18 3/4 = 54 1/2
Explanation for number 4:
1. You know that 4 cup = 1 quart right?
9.44 = 1 quart
2. So you divide it:

Answer:
x = 10
The shaded angles are each 31 degrees.
Step-by-step explanation:
I don't know if you are being asked to solve for x or the shaded angle, so we'll solve for both.
Those 2 shaded angles are equal to each other. So set them equal to each other & solve for x.
91-6x = 4x-9
91+9 = 4x+6x
100 = 10x
10 = x
Now substitute x=10 to find the measure of the shaded angles (which are equal).
91-6x = 91-6(10) = 91-60=31
The shaded angles are both 31 degrees .

There are 4 possible outcomes: 2, 3, 4, 5
There are 3 outcomes that are a number greater than 2: 3, 4, 5
There is 1 outcome that is a number less than 3: 2
p(greater than 2) = 3/4
p(less than 3) = 1/4
p(greater than 2 followed by less than 3) = 3/4 × 1/4 = 3/16
