Answer:
The value of y is directly proportional to the value of x. When x = 4.25, the value of y is 2. What is the value of x when y = 8?
Step-by-step explanation:
Answer:
x = 17 when y = 8
Step-by-step explanation:
Considering the value of y,
→ 8 ÷ 2
→ 8/2 = 4
Now the value of x will be,
→ x = 4.25 × 4
→ [ x = 17 ]
Hence, the value of x is 17.

A building has a height of 125 meters and a length of 80 meters. On a scale drawing of the
building, the height is 25 centimeters.
What is the length of the building on the scale drawing in centimeters?
2.
HELP ME PLZZZ
Answer:
16 cmStep-by-step explanation:
Use ratios to solve:
125 m ⇒ 25 cm80 m ⇒ x cmFind the value of x:
x = 80*25/125 = 16The length of the building on the scale drawing for the given context is obtained as: 16 cm.
How are scale drawings formed?For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.
Then it means
[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]
All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.
For the given case, The height of the building 125 meters was drawn as 25 cm in the scale drawing.
That means:
[tex]\rm 125 \: m : 25 \: cm\\\\1 \: m : \dfrac{25}{125} \: cm\\\\1 \: m :\dfrac{1}{5} \: \rm cm[/tex]
Since the length of the building in reality is 80 meters.
Thus, in scale drawing, it would become:
[tex]\rm 80 \: m = 80 \times 1 \: m : 80 \times \dfrac{1}{5} \: cm = 16 \: \rm cm[/tex]
Thus, The length of the building on the scale drawing for the given context is obtained as being of 16 cm.

Please help me, I’m not very good at Pythagorean Theorem. The picture of the problem is attached. Really appreciate it
Answer:
14.4 inStep-by-step explanation:
The diagonal is the hypotenuse of the triangle with sides of 20.8 cm and 30.6 cm.
Find the length of the diagonal using Pythagorean:
[tex]d=\sqrt{20.8^2+30.2^2}=\sqrt{1344.68 } =1344.68 cm[/tex]Convert the length to inches:
36.67/2.54 = 14.4 inAnswer:
37 cm = 14.57 in
Step-by-step explanation:
A rectangle is a 4-sided shape with 2 pairs of congruent, parallel sides (width and length).
All interior angles of a rectangle are 90°.
The diagonal of a rectangle forms 2 congruent right triangles.
Diagonal = hypotenuse of the right triangleWidth and length = legs of the right triangleGiven:
Width of rectangle = 20.8 cmLength of rectangle = 30.6 cmPythagoras Theorem
[tex]a^2+b^2=c^2[/tex]
where:
a and b are the legs of the right trianglec is the hypotenuse (longest side) of the right triangleTherefore:
a = 20.8b = 30.6c = diagonalSubstitute the given values into the formula and solve for c:
[tex]\implies 20.8^2+30.6^=c^2[/tex]
[tex]\implies c^2=1369[/tex]
[tex]\implies c=\sqrt{1369}[/tex]
[tex]\implies c=37\:\:\sf cm[/tex]
Therefore, the length of the diagonal of the rectangle is 37 cm.
Conversion
1 inch ≈ 2.54 cm
To convert the measure of the diagonal to inches, divide 37 cm by 2.54:
[tex]\implies \dfrac{37}{2.54}=14.57 \sf \:in\:\:(2 \: d.p.)[/tex]

Find the measures of the angles of each triangle (in degrees) and classify the triangle as acute/right/obtuse and scalene/isosceles/equilateral (one from each triple)
A=5x - 10 B = 3x C= 2x - 10
Step-by-step explanation:
given :
A=5x - 10
B = 3x
C= 2x - 10
solution:
A+B+C = 180°
5x - 10 + 3x+ 2x - 10 = 180
10x -20 = 180
10x = 200
x = 20
A = 5(20)-10 = 100-10 = 90°
B = 3x = 3(20) = 60°
C = 2x-10 =2(20)-10 =40-10 = 30°
this is the right triangle and scalene triangle

Decide if this statment true or false The area of a circle is 9 pi if and only if its radius is 3
Answer:
True is the most reasonable than False.
Step-by-step explanation:
If we go by "logic", we know that radius and anything that tells you how long, how far, how tall, etc; the value must always be positive.
The area of circle is expressed as:
[tex] \displaystyle \large{A = \pi {r}^{2} }[/tex]
Where r = radius
Since we know that radius cannot be negative going with logic and real basic geometry, the only radius that satisfies A = 9π is r = 3.
[tex] \displaystyle \large{A = \pi {3}^{2} } \\ \displaystyle \large{A = 9\pi }[/tex]
Now if we do not go by logic of real basic geometry, such as length being negative and all.
Since A = 9π, substitute A = 9π in.
[tex] \displaystyle \large{9\pi = \pi {r}^{2} }[/tex]
Divide both sides by π.
[tex] \displaystyle \large{ \frac{9\pi}{\pi} = \frac{\pi {r}^{2} }{\pi} } \\ \displaystyle \large{ 9 = {r}^{2} }[/tex]
Square both sides, adding plus-minus, apply QE.
[tex] \displaystyle \large{ \pm \sqrt{9} = \sqrt{ {r}^{2} } } \\ \displaystyle \large{ \pm 3 = r}[/tex]
So r = ±3 or radius = +3 and -3
So r can be both 3 or -3 if we do not follow logic itself.
However, the answer should be true instead of false as radius being only positive sounds more logical and reasonable rather than radius being negative.
Write the binomial expansion of (t-3)^5
Answer:
Step-by-step explanation:
(t-3)^5 is the same as (t + (-3))^5
First: t starts at the highest power and goes down and (-3) starts at the lowest power and goes up
Second: from the Pascal triangles take the coefficients 1 5 10 10 5 1
