The length of a shadow of a building is 26 m. The distance from the top of the building to the tip of the shadow is 31 m. Find the height of the building. If
necessary, round your answer to the nearest tenth.
Answers
Answer:
16.9 m
Step-by-step explanation:
The diagram given that represents this situation is a right triangle.
The height of the building can be found using the pythagorean theorem, a² + b² = c².
Where,
a = 26 m
b = height of the building = h
c = 31 m
Plug in the values into the formula
Thus:
[tex] 26^2 + b^2 = 31^2 [/tex]
[tex] 676 + b^2 = 961 [/tex]
Subtract 676 from each side
[tex] b^2 = 961 - 676 [/tex]
[tex] b^2 = 285 [/tex]
Square both sides
[tex] b = \sqrt{285} [/tex]
[tex] b = 16.9 m [/tex] (nearest tenth)

Answers
Answer:
4/7 > x > -11/7
Step-by-step explanation:
First, add -4/3 to all parts
then divide all parts by -7/3
so, We need to separate it into two inequalities
[tex] \frac{4 - 7x}{3} > 0[/tex]
[tex] \frac{4 - 7x}{3} < 5[/tex]
then we solve for x,
[tex] \frac{4 - 7x}{3} > 0 = x < \frac{4}{7} [/tex]
[tex] \frac{4 - 7x}{3} < 5 = x > - \frac{11}{7} [/tex]
so we ended up like this
[tex]x = ( - \frac{11}{7} \frac{4}{7})[/tex]

solve as multi-step eqaution 24(34 + r) = 1200
Answers
The value of 'r' in the expression 24(34 + r) = 1200 is 16.
What are the basic properties of arithmetic laws of operations?There are three types of basic arithmetic laws of operation.
Commutative law for addition and multiplication states,
a + b = b + a.
a×b = b×a.
Distributive law states,
a(b ± c) = ab ± ac.
Associative law states,
a + (b + c) = (a + b) + c.
Given, An expression 24(34 + r) = 1200.
First, we'll distribute LHS,
24×34 + 24×r = 1200.
816 + 24r = 1200.
24r = 1200 - 816.
24r = 384.
r = 384/24.
r = 16.

y = 2x + 8
Step-by-step explanation:
You can see that the line crosses the y-intercept at 8 which is point (0, 8). From that y-intercept point you rise 2 then run 1 to get to point (2, 12), this rise over run is your slope 2/1 or simply 2.
y = mx + b
m is your slope
b is your y-intercept
y = 2x + 8
Triangles H J K and L M N are shown. The triangles have identical side lengths and angle measures. Triangle H J K is slightly lower and to the left of triangle L M N. Triangle H J K is reflected to form triangle L M N.

Translate K to N and reflect across the line containing JK.
Translate H to L and reflect across the line containing JK.

Answers
Answer:B
Step-by-step explanation:
Transformation involves changing the position of a shape.
To map ΔHJK to ΔLMN, we (b) Translate K to N and reflect across the line containing JK.
ΔHJK and ΔLMN are similar triangles; this means that the following sides are corresponding:
HJ and LMHK and LNJK and MNThe first translation would be to translate corresponding sides K to N.
Then triangle HJK must be translated across a line that contains point K (i.e. either line JK or line HK)

Lon is selling gift baskets at a craft fair. His costs are $75 for the table and $12 per basket. He sells each basket for $20.
1. Let b equal the number of baskets. Which expression represents Lon's costs? *
A- 12b - 75
B- 12b +75
C- 20b - 75
D- 20b -12b
2. How many baskets must be sold to make a profit? Solve this inequality to find out. 20b > 12b + 75 (hint: remember it's asking to make a profit) *
A- fewer than 9
B- fewer than 10
C- at least 10
D- more than 12
Answers
Answer:
1. B
2. D
Step-by-step explanation:
1. Lon's cost would be the $12 per basket times how many baskets he sells, in this case b plus the cost of the table. Lon's expression is 12b + 75
2. He needs a profit and the only way he could make that profit is if he sells more than 12.
20b > 12b + 75
20 (12) > 12 (12) + 75
240 > 140 + 75
240 > 215
