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

Trevion is training for a marathon. In February, he ran XLVII miles for his training. In January, he was only able to run XXIV miles. How many more did he run in February than in January?
Answer:he ran 23 miles / XXIII miles more in February than March
Step-by-step explanation:
February = He ran XLVII --- converting to numbers becomes
XL= 40
VII= 7
XLVII= 47
In march he ran XXIV--- converting to numbers becomes
XX= 20
IV= 4
XXIV= 24
Step 2
To find how many more he ran in February than March
Miles ran in February - Miles ran in March
47- 24=23.
Therefore he ran 23 miles / XXIII miles more in February than March

What is 1/2 x -2=2(-x+1)
Answer:
x is equal to one and three fifths, or 1.6
Step-by-step explanation:
[tex]\frac{1}{2}x - 2 = 2(-x + 1)\\\frac{x}{2} - 2 = -2x + 2\\\frac{x}{2} + 2x = 2 + 2\\x + 4x = 4 + 4\\5x = 8\\x = 1.6[/tex]

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]
➋Second: Plug in.
[tex]y = 3x + 5[/tex]

At top speed, a fox can cover 7 miles in 12 minutes. If a fox could continue at this rate indefinitely, how long would take the fox to cross the 210 mile trail of the
Sonoran Desert?
Answer:
It would take 6 hours for the fox to cross the 210 mile trail of the Sonoran Desert.
Step-by-step explanation:
210 miles divided by 7 miles is 30 miles. 30 miles multiplied by 12 minutes is 360 minutes or 6 hours.
Answer:
6 hours
Step-by-step explanation:
Not sure if this is correct, sorry if it isnt but basically I did 210/7 and got 30, then 30 x 12 to figureout how long it would take, i got 360 minutes and 360 min = 6 hours

4. moves down 4
plz solve this question for me
Answer:
a = 16 and b = 13
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, so
CD = AB , that is
3a - 10 = 2a + 6 ( subtract 2a from both sides )
a - 10 = 6 ( add 10 to both sides )
a = 16
The diagonals of a parallelogram bisect each other, so
AO = CO , that is
2b = 26 ( divide both sides by 2 )
b = 13

Answer:the first one is d and the third one is 65% and I think the second one is 5 hours
Step-by-step explanation:
(PLZ READ )all you have to do to get the answer for the first one is divide for example on D it says 1 and then 5 and 2 and 10 first you divide 1 by 5 then 2 by ten and if they ALL have the same answer then they are proportional even if one does not have the same as All the rest it is not proportional.
and for the third one you can search it up
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]
Hence, options A and D are true.
