Can someone find the surface area of the composite shape and show work! I’ll give 30pts! Thanks!
Answer:
382 cm²
Step-by-step explanation:
The shape can be decomposed into two rectangular prism or cuboids
✔️Dimension of prism 1 (smaller prism):
L = 10 cm
W = 3 cm
H = 7 - 4 = 3 cm
Surface area of prism 1 = 2(LW + LH + WH)
= 2(10*3 + 10*3 + 3*3)
= 2(69)
Surface area of prism 1 = 138 cm²
✔️Dimension of prism 2 (larger prism):
L = 10 cm
W = 8 cm
H = 4 cm
Surface area of prism = 2(LW + LH + WH)
= 2(10*8 + 10*4 + 8*4)
= 2(152)
Surface area of prism 2 = 304 cm²
✅Surface Area of the composite shape = (Surface area of prism 1 + surface area of prism 2) - (2 × area of the base of prism 1)
= (138 + 304) - (2 × L × W)
= 442 - (2 × 10 × 3)
= 442 - 60
= 382 cm²

What is hypotenuse?"It is the longest side of the right triangle."
What is Pythagoras theorem?"For a right triangle,

For given question,
We need to write a function that models the relationships among x, y, and r.
Consider a right triangle ABC.
where AB = x, BC = y and hypotenuse AC = r
Using Pythagoras theorem,
[tex]x^{2} + y^{2} =r^{2}[/tex]
above function defines the relationships among x, y, and r.
Now we solve above equation for 'r',
[tex]\Rightarrow r^2=x^2+y^2\\\\\Rightarrow r=\sqrt{x^2+y^2}[/tex]
Therefore, the function that models the relationships among x, y, and r is [tex]r=\sqrt{x^2+y^2}[/tex]

Step-by-step explanation:
1. What is the horizontal distance that your bridge must span to clear the ravine? (1 point)
150 feet.
2. Write a function that models the relationships among x, y, and r. (Hint: Use the Pythagorean theorem.) Then solve the equation for r in terms of x and y. (3 points: 1 point for the correct Pythagorean setup, 1 point for work, 1 point for the solution)

Answer: D or #4: None of the above
Step-by-step explanation: Since the longest angle is 13 x has to be around half because its a 47 degree angle if we round it would be 6 so D
Can a trangle have lengths of 1 , 1 and 6
Answer: No it can't
You can prove this with Pythagorean theorem. (a^2+b^2=c^2) In this case, 6 is the highest number so we know it has to be the hypotenuse. So plug it into the equation, 1^2+1^2=6^2, and simplify. You will get 2=36, and we know that is not true, so a triangle can't have the lengths of 1, 1, and 6.

2x-7= -5x+14
with explanation pls.
First, add 7 to both sides of the equation so it would be;
2−7=−5+14
2−7 + 7=−5+14+7
To simplify this it would be:
2=−5+21
Add 5 to both sides, it would look like this:
2=−5+212+5=−5+21+5
To simplify it would be;
7=21
Divide both sides of equation with once again, the same number
7=21 77=217
Simplify it;
=3
Therefore your answer is;

Answer:
Number of 45° angles = 1
Number of 90° angles = 1
Number of 135° angles = 3
Step-by-step explanation:
From the figure attached,
Angles in Figure D are,
Measure of angle A = 45°
Measure of angles B = 45° + 90° = 135°
Measure of angle C = 90° + 45° = 135°
Measure of angle D = 45° + 90° = 135°
Measure of angle E = 90°
Therefore, number of 45° angles = 1
Number of 90° angles = 1
Number of 135° angles = 3

A bank compares two proposals to increase the amount that its credit card customers charge on their cards. (The bank earns a percentage of the amount charged, paid by the stores that accept the card). Proposal A offers to eliminate the annual fee for customers who charge $2,400 or more during the year. Proposal B offers a small percent of the total amount charged as a cash rebate at the end of the year. The bank offers each proposal to an SRS of 150 of its existing credit card customers. At the end of the year, the total amount charged by each customer is recorded. Here are the summary statistics:
Group n x s
A 150 $1,987 $392
B 150 $2,056 $413
A) Do the data show a significant difference between the mean amounts charged by customers offered the two plans?
B) The distributions of amounts charged are skewed to the right, but outliers are prevented by the limits that the bank imposes on credit balances. Do you think that skewness threatens the validity of the test? Explain.
Answer:
a) There is no significant difference between the mean amounts charged
b) The skewness threatens the validity of the test

Answer :
to find area of the square = 6 to the power 2
to find the area of the rectangle = (5x + 12) * 5x
therefore,
square's area = 36
rectangle's area = 5x*5x + 12 * 5x
= 25x * 60x
Now we have to find the sum of both the areas,
so, 36 + 1500 = 1536

a dance club spent $922 on 40 items.The item include some hats and pairs of shoes.Each hat cost $19 and each pair of shoes cost $25.How many pairs of shoes did the dance club buy?
1. H+S=40
2. 19H+25S=922
From 1,
19H+19S=760
Subtract this from 2 to eliminate H,
19H+25S-19H-19S=922-760
6S=162
Solve for S, then use either equation to solve for H.

Choose the correct graph of the function Y = Vx+1
Answer:
The graph for y=[tex]\sqrt{x}[/tex]+1 looks like this. Hope this helped you :D
Step-by-step explanation:
The required graph of y = √x + 1 is a curve that starts from the point (0,1) and rises continuously as x increases.
What is the graph?The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The equation y = √x + 1 represents a simple algebraic function in which the value of y is dependent on the value of x.
When we plot this function on a graph with x on the horizontal axis and y on the vertical axis, we get a curve that starts from the point (0,1) and continues upward as x increases.
At x=0, the value of y is 1. As x increases, the value of y increases as well, but at a slower rate because of the square root function. As x approaches infinity, the value of y also approaches infinity, but again at a slower rate than a linear function.
Since the domain of the function is all non-negative real numbers (x ≥ 0), the graph of the function exists only in the first quadrant of the coordinate plane.
Overall, the graph of y = √x + 1 is a curve that starts from the point (0,1) and rises continuously as x increases.

Kayla earns $10.75 per hour babysitting. How much will she earn for a job that lasts from 8:30 a.m. to 4:30 p.m.
Answer:
$86
Step-by-step explanation:
8 hours times 10.75
Answer: $86.00
Step-by-step explanation:
8 to 9 , 9 to 10, 10 to 11, 11 to 12, 12 to 1 , 1 to 2, 2 to 3 , 3 to 4 come up to 8 hours.
4:00 to 4: 30 is half hour.
So 8:00 to 4: 30 come up to 8 1/2 hours (eight and half hours ).
8:30 am to 4:30 pm= 8 hours.

A line that includes the point (6, 1) has a slope of 9. What is its equation in point-slope form?
Use the specified point in your equation. Write your answer using integers, proper fractions,
and improper fractions. Simplify all fractions.
Y-
(x-)
Answer: [tex](y-1)=9(x-6)[/tex]
Step-by-step explanation:
If a line is passing through the point (a,b) and has a slope m, then the equation of the line in point-slope form is given by :-
[tex](y-b)=m(x-a)[/tex]
Given: A line that includes the point (6, 1) has a slope of 9.
The equation of line in point-slope form: [tex](y-1)=9(x-6)[/tex]
Hence, the required equation in point slope form: [tex](y-1)=9(x-6)[/tex]
