On a sunny day, Larry notices that his shadow is 24 inches long. If it is 74 inches from the top of his head to the end of the shadow, how tall is Larry?
Answer:
70 inches
Step-by-step explanation:
Larry forms a right triangle with the ground (this is one leg of a right triangle) and he is 24 inches from his shadow (this is the second leg).
74 inches is the hypotenuse of the right triangle
use pythagorean theorem: a^2 + b^2 = c^2
let h = Larry's height
h^2 + 24^2 = 74^2
h^2 + 576 = 5476
h^2 = 4900
h = sq rt 4900
h = 70

Start by finding the scale of this map. At the actual gym, one side length of the snack stand is 60 feet. On the scale map, it is 20 cm. What is the scale?
Answer:
I actual foot represents 0.01093 foot on paper
Step-by-step explanation:
Given that :
Actual side length of snack stand = 60 feets
Length of side on map = 20cm
Scaie :
60 feet = 20cm
1 foot = (20/60) cm
1 foot = 0.333 cm
1cm = 0.0328084 foot
0.333cm = (0.33 * 0.0328084) = 0.01093 feets
Scale :
I actual foot represents 0.01093 foot on paper

A 35 foot ladder is leaning against a building. The base of the ladder is 21 feet from the side of the building. How high does the ladder reach along the side of the building?
Answer:
28 feets
Step-by-step explanation:
Given that:
Height of ladder = 35
Distance between foot of ladder and wall base = 21 feets
The height of the ladder = h
Kindly refer to attachment for diagram illustration :
Using Pythagoras rule :
h² = 35² - 21²
h² = 1225 - 441
h² = 784
h =sqrt(784)
h = 28 feets
Height of ladder along the side of the building = 28 feets

Which of the following is logically equivalent to “I wear a jacket if it is cold outside." ?
If I wear a jacket, then it is cold outside.
If I do not wear a jacket, then it is not cold outside.
I wear a jacket if and only if it is cold outside.
If it is not cold outside, then I do not wear a jacket.
The option from the following that is logically equivalent to the statement is that: If it is not cold outside, then I do not wear a jacket.
What is Logical equivalence?Two statements are regarded to be logically equivalent if, and only if, their resultant forms are logically equivalent during the time at which identical statement variables are utilized to illustrate their component statements.
Similarly; two statement forms are noted to be logically equivalent if, and only if, their resultant truth tables show an identical form per variation of statement variables.Therefore, we can conclude that the correct option that is logically equivalent to the statement being made is that: If it is not cold outside, then I do not wear a jacket.

Answer:
The answer is
[tex]y = 3x + 5[/tex]
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ↶
[tex]y = mx + b[/tex]
❃Since we already have the slope, we don't need to solve for that.
➊ First: We are going to find the y-intercept.
[tex]y = mx + b \\ 2 = 3( - 1) + b \\ 2 = - 3 + b \\ \frac{ + 3 = + 3 \: \: \: \: \: }{5 = b}[/tex]

Which expressions are equivalent to
?
1/5x1/5x1/5x1/5
Choose 2 answers:
Answer:
we conclude that:
[tex]\left(5^{-2}\right)^2=5^2\cdot \:\:\:5^{-6}=\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}[/tex]
Hence, options A and D are true.
Step-by-step explanation:
Given the expression
[tex]\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\cdot \frac{c}{d}=\frac{a\:\cdot \:c}{b\:\cdot \:d}[/tex]
[tex]\frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}\cdot \frac{1}{5}=\frac{1\cdot \:\:1\cdot \:\:1\cdot \:\:1}{5\cdot \:\:5\cdot \:\:5\cdot \:\:5}[/tex]
[tex]=\frac{1}{5\cdot \:5\cdot \:5\cdot \:5}[/tex]
[tex]=\frac{1}{5^4}[/tex]
[tex]=\frac{1}{625}[/tex]
Checking options B and C:
Option B
[tex]\left(5^{-4}\right)^0=1[/tex]
Option C
[tex]\frac{5^1}{5^4}=\frac{5}{625}=\frac{1}{125}[/tex]
Thus, options B and C are not equivalent!
Checking Option A
Option A
[tex]\left(5^{-2}\right)^2[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0[/tex]
[tex]\left(5^{-2}\right)^2=5^{-2\cdot \:2}[/tex]
[tex]=5^{-4}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=\frac{1}{5^4}[/tex]
[tex]=\frac{1}{625}[/tex]
Now, checking option D
Option D
[tex]5^2\cdot \:5^{-6}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}[/tex]
[tex]5^2\cdot 5^{-6}=5^{2-6}[/tex]
[tex]=5^{-4}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}[/tex]
[tex]=\frac{1}{5^4}[/tex]
[tex]=\frac{1}{625}[/tex]
Therefore, we conclude that:
[tex]\left(5^{-2}\right)^2=5^2\cdot \:\:\:5^{-6}=\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}\cdot \:\:\frac{1}{5}[/tex]

I am very horrible at explaining these things, especially why it's 3 to the left and not to the right, but you'll have to trust me on that one.
As far as the 5 up part, you take the function (x+3)^2 and you always add 5, raising every output by 5.

Which expressions are equivalent to x/3x times 8x/3x? Select all that apply?
a. 8x^2/9x^2
b. 8x^2/3x
c. 8x/3, for x not equal to 0
d. 8/9, for x not equal to 0
e. 9x^2/9x^2
f. 1, for x not equal to 0
Answer:
A, D
Step-by-step explanation:
x/3x times 8x/3x is equivalent to x(8x)/[(3x)(3x)] i.e. 8x^2/9x^2 or 8/9.
A is correct obviously.
B is not correct since the coefficients and degrees are different.
C is not correct since the coefficients and degrees are different.
D is correct.
E is obviously wrong by comparing the coefficients.
F is also wrong since 8/9 is not equal to 1.
So the correct answers are A and D.
The expressions equivalent to (x/3x) * (8x/3x) is 8/9 and 8x² / 9x²
An equation is an expression that is used to show the relationship between two or more variables and numbers.
Given the equation:
(x/3x) * (8x/3x)
Multiplying the numerator and denominator:
= (x * 8x)/(3x * 3x)
= 8x² / 9x²
Further simplifying the equation:
= 8/9
The expressions equivalent to (x/3x) * (8x/3x) is 8/9 and 8x² / 9x²

For a fundraiser, a group plans to sell granola bars and bottles of water at the same prices as described in Part A. The group wants the income from the fundraiser to be at least $150. Choose the inequality to show the number of granola bars x and the number of bottles of water y that must be sold.
Incomplete question. The missing part read;
Ten granola bars and twelve bottles of water cost $23. Five granola bars and four bottles of water cost $10.
Options:
A. 1.4x + 0.75y > 150
B. 1.4x + 0.75y ≥ 150
C. 1.4x + 0.75 < 150
D. 1.4x + 0.75 ≤ 150
Answer:
B. 1.4x + 0.75y ≥ 150
Step-by-step explanation:
Remember, from the question we are told that the group wants the income from the fundraiser to be at least $150, meaning, they are not against having an income above $150 from the fundraiser, but a minimum of at least that amount.
Hence, among all the listed options, the correct inequality sign to represent the number of granola bars 'x' and the number of bottles of water 'y' that must be sold is the ≥ (equal to or greater than sign).
