Answers
To add these fractions, we need to find a common denominator. The least common multiple of 7, 4, and 3 is 84, so we will use 84 as the common denominator.
2/7 + (-3/4) + (-2/7) + 4/3
= (2/7) * (12/12) + (-3/4) * (21/21) + (-2/7) * (12/12) + (4/3) * (28/28) (multiplying each fraction by an equivalent form to get a common denominator of 84)
= 24/84 - 63/84 - 24/84 + 112/84 (simplifying each fraction)
= -51/84 + 112/84 (combining like terms)
= 61/84 (simplifying the resulting fraction)
Therefore, 2/7 + (-3/4) + (-2/7) + 4/3 = 61/84.
Answer:
7/12
Step-by-step explanation:
2/7 + (-3/4) + (-2/7) + 4/3
2/7 - 3/4 - 2/7 + 4/3 (+ * - = -)
2/7 - 2/7 - 3/4 + 4/3 (Distribution Property)
0 - 3/4 + 4/3
- 3/4 + 4/3
4/3 - 3/4 (Distribution Property)
LCM = 3 * 4
= 12
(16 - 9) / 12
7/12
So, the final answer is 7/12.

Joseph has a fair dice with 4 faces numbered 1 to 4.
He also has a fair dice with 6 faces numbered 1 to 6.
He rolls both dice.
Find the probability of rolling a different number on each dice.
Answers
Answer:
To find the probability of rolling a different number on each dice, we can determine the total number of possible outcomes and the favorable outcomes.
The total number of possible outcomes when rolling a 4-sided die and a 6-sided die is the product of the number of sides on each die: 4 × 6 = 24.
The favorable outcomes occur when we roll a different number on each die. We can calculate this by considering all the possible combinations.
For the first die (4-sided), there are 4 possible outcomes.
For the second die (6-sided), there are 6 possible outcomes.
Since we want different numbers on each die, the total number of favorable outcomes is 4 × 6 = 24.
Therefore, the probability of rolling a different number on each die is:
Probability = (Number of favorable outcomes) / (Number of total outcomes)
Probability = 24 / 24
Probability = 1
Hence, the probability is 1 or 100%.

Answer:
282 cubic inches
Step-by-step explanation:
Let's have A be the top figure, B the middle, and C the bottom.
First, we need the volume for A, B, and C. And after, add them up.
Figure A : 1 · 5 · 2 = 10 cubic inches
Figure B : 3 · 3 · 8 = 72 cubic inches
Figure C : 10 · 4 · 5 = 200 cubic inches
Now we add A+B+C, so the equation is:
10+72+200=282 cubic inches
Hence, the volume of the this figure is 282 cubic inches.

Answers
Answer:
a) If the volume of the prism on the left is 1029 m³, then the volume of the prism on the right is 1536 m³.
b) If the height of the prism to the left is 14 m, the height of the prism to the right will be 16 m.
c) If the surface area of the prism to the left is 392 m², the surface area of the prism to the right will be 512 m².
Step-by-step explanation:
a) To solve, set up a proportion. Volume is three-dimensional, so we need to cube.
(7/8)³=1029/x
Now we can solve using cross products to get 1536.
If the volume of the prism on the left is 1029 m³, then the volume of the prism on the right is 1536 m³.
b) To solve the second one, we also set up a proportion. Height is one-dimensional, so we will not need exponents here.
7/8=14/x
Solve using cross products to get 16.
If the height of the prism to the left is 14 m, the height of the prism to the right will be 16 m.
c) Now we are solving for area, which is two-dimensional. Therefore, we will need to square.
7/8²=392/x
Solve using cross products to get 512.
If the surface area of the prism to the left is 392 m², the surface area of the prism to the right will be 512 m².

What is 2x+21? Please it's due in about 15 minutes!!!
Answers
Answer:
The value of x is 21
Step-by-step explanation:
2x+21 is a linear equation with one unknown, x. To solve for x, we can use the following steps:
1. Subtract 21 from both sides of the equation. This will isolate x on the left-hand side of the equation.
```
2x+21 - 21 = x
```
2. Divide both sides of the equation by 2. This will divide both sides of the equation by 2, which will cancel out the 2 on the left-hand side of the equation, leaving x by itself.
```
x = (2x+21)/2
```
3. Simplify the right-hand side of the equation.
```
x = x/2 + 21/2
```
4. Combine like terms on the right-hand side of the equation.
```
x = (1/2)x + 21/2
```
5. Subtract (1/2)x from both sides of the equation. This will isolate x on the left-hand side of the equation.
```
x - (1/2)x = (1/2)x + 21/2 - (1/2)x
```
6. Simplify the right-hand side of the equation.
```
(1/2)x = 21/2
```
7. Multiply both sides of the equation by 2. This will multiply both sides of the equation by 2, which will cancel out the (1/2) on the left-hand side of the equation, leaving x by itself.
```
2*(1/2)x = 21/2 * 2
```
8. Simplify the right-hand side of the equation.
```
x = 21
```
Therefore, the value of x is 21.
2x+21
2x+21=0
-21/2
X = -21/2 or -10.5

What is a high degree of overlap ?The dot plots for the two neighborhoods show a high degree of overlap, it would suggest that the distribution of the number of people per household in each neighborhood is similar.
This means that there is little difference between the two neighborhoods in terms of the average number of people per household. It is possible that the two neighborhoods have similar average household sizes but differ in other important ways, such as income, education level, or demographics.

so we're really looking for the equation of a line whose slope is -3 and it passes through (-9 , 13)
[tex](\stackrel{x_1}{-9}~,~\stackrel{y_1}{13})\hspace{10em} \stackrel{slope}{m} ~=~ - 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{13}=\stackrel{m}{- 3}(x-\stackrel{x_1}{(-9)}) \implies y -13 = - 3 ( x +9) \\\\\\ y-13-3x-27\implies {\Large \begin{array}{llll} y=-3x-14 \end{array}}[/tex]
Answer:
m = 1/3
m⊥ = -3
x1 = -9
y1 = 13
point slope: y-13 = -3(x+9)
slope intercept: y= -3x-14
Step-by-step explanation:
Equation given is in y=mx+b form, so I think m=1/3 (or whatever is right before the x cause it is little hard to see)
To find a perpendicular slope, you use the negative reciprocal of the given slope, so the perpendicular slope would be m=-3
x1 and y1 would be the given coordinates so -9 and 13 respectively
Finally plug in all this info into point slope form equation (y-y1 = m(x-x1)
Point slope would be: y-13 = -3(x+9)
Slope intercept would be: y= -3x-14

The whole shape is a rectangle, with a length of 6 and a width of 7.
To find the area, multiply 6 by 7=42yd^2
The area of the entire shape is 42yd^2
Now, the vertical 4yd side plus the height of the dotted triangle will equal 6yd.
So the height of the dotted triangle is 6-4=2yd.
The horizontal 4yd side plus the base of the dotted triangle will equal 7yd.
So the base of the dotted triangle is 7-4=3yd.
Formula for area of triangle: 1/2 x base x height
1/2 x 4 x 3= 6yd^2
The area of the dotted triangle is 6yd^2
Now subtract the area of the whole shape by the area of the dotted triangle to get the shaded region.
42-6= 36yd^2
Area of shaded region: 36yd^2 (i think)

Answers
The first watch is 58 and the other watch is 42
The requreid, The absolute value equation to represent this situation is 0 = |x - 50| + 8 and Elena finds a watch that costs $50. The other two watches are priced at $42 and $58.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Part A:
Let x be the price of the first watch she finds. Then the price of the second watch is x - 16 (since it is $8 below her budget).
The absolute value equation to represent this situation is:
0 = |x - 50| + 8
Part B:
To solve the absolute value equation, we need to consider two cases:
Case 1: x - 50 is positive
If x - 50 is positive, then we can write the equation as:
0 = x - 50
x = 50
This means that the watch Elena finds costs $50, which is exactly her budget.
Case 2: x - 50 is negative
If x - 50 is negative, then we can write the equation as:
0 = -(x - 50)
0 = -x + 50
x = 50
Again, this means that the watch Elena finds costs $50.
So, Elena finds a watch that costs $50. The other two watches are priced at $42 and $58.
