HELP ASAP YALL- PLS
Answer: x = 4
Step-by-step explanation:
since it is showing us that the angles are congruent, we know that the smaller triangle is just a scaled-down version of the larger one. in other words, it is the EXACT SAME triangle, just slightly smaller.
so, i redrew them next to each other, so i could compare them easily.
i looked at the corresponding sides that were given, and realized that the side that is 10 on the larger triangle is equal to 5 on the smaller triangle. the side that is equal to 6 on the larger triangle is equal to 3 on the smaller triangle. this concludes that the smaller triangle is exactly half the size of the larger triangle!
so, i figured (using logic) that x must equal 4, simply dividing its corresponding side (with a measure of 8) in half.
hope this helps! xoxo
1 Camelita nuns the track at her school that is of a milelong. If she runs 4. 3 miles, how many laps did she run?
Answer:
3 laps.
Step-by-step explanation:
Hi! I can see how this is tricky, but I was a bit confused by the 4 in "If she runs 4." It says in the problem that the track is a mile long... So if you run the track 3 times, 3 x 1 = 3.

What is x?
(4/5)^x=64/125
Answer:
x = 3
Step-by-step explanation:
(4/5)^x = 64/125 means that 4^x / 5^x = 64/125
x can only be 3 because 4^3 = 64 and 5^3 = 125

MN = TS
5x -2 = 3x + 1
Add 2 to both sides:
5x = 3x + 3
Subtract 3x from both sides:
2x = 3
Divide both sides by 2
X = 3/2
Now you have x solve for TS
TS = 3x + 1 = 3(3/2) + 1 = 4 1/2 + 1 = 5 and 1/2

Give your answer to 3 significant figures.
с
410
13.5 cm
A
B
Answer:
AB ≈ 8.86 cm
Step-by-step explanation:
Using the sine ratio in the right triangle
sin41° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{13.5}[/tex] ( multiply both sides by 13.5 )
13.5 × sin41° = AB , then
AB ≈ 8,86 cm ( to 3 significant figures )
Answer:
8.87
Step-by-step explanation:
use the sin law for right triagles sin(θ)= opposite/hypotenuse so
sin(41)=(AB)/13.5
13.5×sin(41)=AB
8.87=AB

Evaluate (-4)^(-2)..........................................................................................................
Answer:
[tex](-4)^{2} = \frac{1}{16}[/tex]
Step-by-step explanation:
Explanation:-
Given (-4)⁻²
we will apply (a)⁻ⁿ = [tex]\frac{1}{a^{n} }[/tex]
(-4)⁻² = [tex]\frac{1}{(-4)^{2} }[/tex]
[tex]= \frac{1}{(-1)^{2} (4)^{2} }[/tex]
[tex]= \frac{1}{16}[/tex]
[tex](-4)^{2} = \frac{1}{16}[/tex]

Find the first 5 terms in the sequence...
Answer:
The first '5' terms of the given sequence
[tex]\frac{7}{2} , 4 ,\frac{9}{2} ,5,\frac{11}{2}[/tex]
Step-by-step explanation:
Explanation:-
Given that the [tex]n^{th}[/tex] aₙ = [tex]\frac{N}{2} + 3[/tex]
first term
Put n=1 ⇒ [tex]\frac{1}{2} + 3 = \frac{7}{2}[/tex]
second term
Put n=2 ⇒ [tex]\frac{2}{2} + 3 = 1+3=4[/tex]
Third term
Put n=3 ⇒ [tex]\frac{3}{2} + 3 = \frac{3+6}{2}=\frac{9}{2}[/tex]
Fourth term
Put n=4 ⇒ [tex]\frac{4}{2} + 3 = 2+3 =5[/tex]
Fifth term
Put n=5 ⇒ [tex]\frac{5}{2} + 3 = \frac{5+6}{2}=\frac{11}{2}[/tex]
The first '5' terms of the given sequence
[tex]\frac{7}{2} , 4 ,\frac{9}{2} ,5,\frac{11}{2}[/tex]
