Answer:
The first one is 145 in^2 and the other is 250 in^2
Step-by-step explanation:
For the first one you have to find the base first so 5*5=25, then you find the area of the other faces and since theres 4 of them dont bother diving them by 2 and just do it twice, so the faces would be 120 in^2 in all add it together and you get 145
For the second one its the same thing but instead of a square base its a triangle so theres only 3 faces. 8*10 = 80/2 =40, 2 of the faces are 140 in all and to find the last one just 14*10=140/2=70 and you add them together and get 250
A triangle has vertices P(−5, 4), Q(3, 4), and R(−5, −2). S is the midpoint of Segment PQ and T is the midpoint of Segment PR. What is the length of Segment ST?
Segment ST equals six square root of two end square root
Segment ST equals four
Segment ST equals three square root of two end square root
Segment ST equals five
Answer:
Length of ST = mQR/2 = 4
Step-by-step explanation:
S and T are the mid-points of PQ and PR, so ST is parallel to and equal to half the length of QR.
(following corrected due to mistake)
Length of QR = sqrt((3--5)^2+(4--2)^2)=sqrt(8^2+6^2)=10
Length of ST = mQR/2 = 5

8x+2y=32
x+y=7
Step-by-step explanation:
Answer:
It is in fact the second one.
Step-by-step explanation:
It says that he bought a total of 7 tickets and it cost $32.
x represents the number of adult tickets and y represents the number of chid tickets.
So:
x + y = 7 because the adding the number of adult and child tickets should equal the total number bought.
and
8x + 2y = 32 because each adult ticket was 8 dollars and each child was 2 and the total should add up to 32

9514 1404 393
Answer:
4. 8 yds
5. 30 mi
Step-by-step explanation:
The relation according to the Pythagorean theorem is ...
c² = a² + b²
This can be solved for 'a' or 'b' to get ...
a = √(c² -b²)
b = √(c² -a²)
__
4. b = √(17² -15²) = √(289 -225) = √64 = 8
The length of leg b is 8 yards.
__
5. a = √(50² -40²) = √(2500 -1500) = √900 = 30
The length of leg 'a' is 30 mi.

Answer:
[tex]A_{\Delta ABP}=\sin \theta[/tex]
Step-by-step explanation:
Let the center of the circle be O.
Recall that the area of a triangle can be given by:
[tex]\displaystyle A=\frac{1}{2} ab\sin C[/tex]
Where C is the angle between the two sides.
ΔABP is equal to the sum of ΔAPO and ΔBOP.
Let a = OP and b = OB. Since this is the unit circle and PO and BO are radii, they both equal one. C will be θ. Hence, the area of ΔBOP is:
[tex]\displaystyle A_{\Delta BOP}=\frac{1}{2}(1)(1)\sin \theta=\frac{1}{2}\sin\theta[/tex]
For ΔAPO, we can use the two sides OP and OA. Again, they are the radii of the unit circle, so they equal one. The angle in this case will be π - θ radians. Hence:
[tex]\displaystyle A_{\Delta APO}=\frac{1}{2}(1)(1)\sin\left(\pi -\theta\right)=\frac{1}{2}\sin\left(\pi -\theta\right)[/tex]
However, note that sin(π - θ) = sin(θ). Hence:
[tex]\displaystyle A_{\Delta APO}=\frac{1}{2}\sin\left(\theta\right)[/tex]
Hence, the area of ΔABP is:
[tex]\displaystyle A_{\Delta ABP}=\frac{1}{2}\sin \theta+\frac{1}{2}\sin\theta =\sin \theta[/tex]
Find 3 values that satisfy the inequality 4x - 3 < 25
Answer:See explanation
Step-by-step explanation:
The values that can be used to satisfy the inequality 4x - 3 < 25 will be calculated thus. We simply have to get the value of x and this will be:
4x - 3 < 25
4x < 25 + 3
4x < 28
x < 28/4
x < 7.
Therefore, the values that must satisfy the equation must be less than 7 such as 1, 2, 3, 4, 5 and 6.

Which equation represents the graphed function?
O y=-3x + 3
O y = 3x - 3
O y = 3x - 1
O y=-x+3
Answer:
y = -⅓x + 3
Step-by-step explanation:
To find the equation of the graph in the form of y = mx + b (slope-intercept form), we have to find the slope (m) and the y-intercept (b) of the graph:
Slope (m) = change in y/change in x
Slope (m) using the two points on the line, (0, 3) and (3, 2):
m = (2 - 3)/(3 - 0) = -1/3
m = -⅓
y-intercept (b) = 3 (the y-axis is intercepted at this point)
✔️To write the equation, substitute m = -⅓ and b = 3 into y = mx + b:
Thus,
y = -⅓x + 3

Can u help me please??
Answer:
Let C represent the total cost of each deal
Let T be the number of trips down the water slide
C = 32 for the 1st deal since the cost is the same regardless of how much she rides
C = 18 + T for the 2nd deal
To find when the two costs are equal set them equal to each other and solve for T
32 = 18 + T
T = 14 trips
The cost must be $32 since that is the only cost possible for the 1st deal

The amounts of money Brittany earned each week from babysitting for 5 weeks are $12, $62, $70, $54, and $62. The mean amount earned is $52 and the median amount earned is $62. Identify the outlier and describe how the mean and median are affected by it.
Answer:
The outlier is $12, results in a decrease in the mean. Outliers have little influence on the median.
If you actually calculate and try and find an outlier, this dataset doesn't have one. But I'm going to assume they're just looking for an extreme number in the set since it clearly says to identify it
The requried outlier is $12 and it significantly affects the mean by lowering it, but it does not affect the median.
What is the median?When a dataset is ordered, the median is the value that is exactly in the middle. It is a measure of central tendency that distinguishes between the lowest and top 50% of data.
Here,
The outlier in this data set is the first observation of $12, which is significantly lower than the rest of the values.
The mean is calculated by adding all the values and dividing by the number of values. In this case, the mean is:
$12 + $62 + $70 + $54 + $62 = $260
$260 ÷ 5 = $52
When the outlier of $12 is included in the calculation, it significantly lowers the mean.
The median is the middle value when the data set is arranged in order from least to greatest. In this case, the median is $62, which is not affected by the outlier of $12.
Therefore, the outlier is $12 and it significantly affects the mean by lowering it, but it does not affect the median.

Find the equation of the line.
Answer:
y= x - 5
Step-by-step explanation:
The equation of a line is generally y=mx+b.
m= the slope, b= the y-intercept
By looking at the graph we can see the line intercepts the x-axis at (5,0) and the y-axis at (0,-5). With these two points, you can find the slope with the slope formula:
m=y2−y1/x2−x1
Plug in (5,0) and (0,-5):
m= -5 - 0 / 0 - 5
m = -5/-5
m = 1
The slope is equal to 1. You can also confirm this by looking at the graph where the line intercepts each point "up one point, over one point." This is known as the "rise over run."
Now the y-intercept or "b" in the equation is (-5) since the other point has a y-intercept of 0.
So plug these numbers into the line equation, y=mx+b:
m= 1
b= -5
y= mx+5
y= (1)x + (- 5)
y= x - 5
Voila!
The equation of the line is equal to y= x - 5
The general equation of a line is;
y=mx+b.
Where m= the slope, b= the y-intercept
Since we can see the line intercepts the x-axis at (5,0) and the y-axis at (0,-5). With these two points, we can find the slope with the slope formula:
[tex]m=(y_2-y_1)/(x_2-x_1)[/tex]
Substitute in (5,0) and (0,-5)
m= -5 - 0 / 0 - 5
m = -5/-5
m = 1
Now the y-intercept or "b" in the equation is (-5) since the other point has a y-intercept of 0.
So, substitute numbers into the line equation, y=mx+b:
y= mx+5
y= (1)x + (- 5)
y= x - 5

This question did provide some clues to answer this question. Every week, the area covered by the algae is multiplied by 2^1.
To find the area cover increase by the algae per day, the exponent should be divided by 7 since there are 7 days in a week. Hence, every day, the area covered by the algae multiplies by 2^(1/7). In other words, 1 day after the algae was spotted, the area is 12.5 * 2^(1/7), which answers part B.
10 days after the algae was spotted, the area covered by the algae is 12.5 * 2^[(1/7)*10] = 33.6475... , which rounds up to 34 and answers part A.
