Answer:
The measure of angle RST is 80
Step-by-step explanation:
Since they are vertical angles, then they must be equal as vertically opposite angles are equal
Thus;
5b + 20 = 7b - 4
7b - 5b = 20 + 4
2b = 24
b = 24/2
b = 12
But RST = 5b + 20
substitute for b
RST = 5(12) + 20
RST = 60 + 20
RST = 80

Step-by-step explanation:
An architect designs two similar triangular patios. The first patio has angle measures of (x + 10)°, (y + 15)°, and 70°. The second patio has angle measures of (x + 20)°, 50°, and 60°. Find the values of x and y.
Given:
An architect designs two similar triangular patios.
The first patio has angle measures of (x + 10)°, (y + 15)°, and 70°.
The second patio has angle measures of (x + 20)°, 50°, and 60°.
To find:
The values of x and y.
Solution:
We know that, corresponding angles of similar triangles are equal. So, the value of (x + 20)° must be 70°.
[tex]x+20=70[/tex]
[tex]x=70-20[/tex]
[tex]x=50[/tex]
The value of x is 50.
Now,
[tex](x+10)^\circ=(50+10)^\circ[/tex]
[tex](x+10)^\circ=(60)^\circ[/tex]
So, remaining angles must be equal, i.e., (y + 15)° and 50° are equal.
[tex]y+15=50[/tex]
[tex]y=50-15[/tex]
[tex]y=35[/tex]
Therefore, the values of x and y are 50 and 35 respectively.
The values of x and y are 50 and 35 respectively.
The corresponding angles of similar triangles are equal. Therefore,
The first patio angles are:
x + 10
y + 15
70°
The second patio angles are ;
x + 20
50°
60°
Therefore,
x + 20 = 70
x = 70 - 20
x = 50
y + 15 = 50
y = 50 - 15
y = 35

Which correctly explains how to estimate 55 percent of 64? A. Round 55 percent to 40 percent and 64 to 60. Think of 40 percent as 1/4 so 1/4 of 60 is 15 B. Round 55 percent to 60 percent and 64 to 70. Think of 60 percent as 1/3 so 1/3 of 70 is 23.3 C. Round 55 percent to 50 percent and 64 and 70. Think of 50 percent as 1/5 so 1/5 of 60 is 12 or D. Round 55 percent to 50 percent and 64 to 60. Think of 50 percent as 1/2 so 1/2 of 60 is 30
Answer: Choice D
Round 55 percent to 50 percent and 64 to 60. Think of 50 percent as 1/2 so 1/2 of 60 is 30.
===================================================
Explanation:
There are many ways to estimate, but this is probably the easiest since 1/2 = 0.50 = 50%, and taking half of something is fairly straightforward and quick.
Taking half of 60 is like taking half of 6, except we stick at 0 at the end.
Half of 6 is 3
Half of 60 is 30
The estimate of 55% of 64 is 30
The actual value is
55% of 64 = 0.55*64 = 35.2
which isn't too far off.
-------------------------
Extra info:
Choice A is false because 40% is not equal to 1/4. Instead 1/4 = 0.25 = 25%Choice B is false because 1/3 = 0.333 = 33.3% approximately, so 1/3 is not equal to 60%Choice C is false because 1/5 = 0.20 = 20% and not 50%please help me out .

Answer:
The amount of time Jill spent to do her homework
= 9 1/2 hours. which equals to 570 minutes.
Which means, the amount of times Jack needed to do his is
= 570 minutes x 1.5
= 855 minutes which equals to 14 1/4 hours
hope this helps
Answer:
Step-by-step explanation:
1) Time spent by Jack = Time spent by Jill * 1 1/2
[tex]= 9\frac{1}{2}*1\frac{1}{2}\\\\=\frac{19}{2}*\frac{3}{2}\\\\=\frac{19*3}{2*2}\\\\=\frac{57}{4}\\\\=14\frac{1}{4} hours[/tex]
2) Time spent by Jill = Time spent by Jack ÷ 1 1 /2
= 18 1/4 ÷ 1 1/2
= 73/ 4 ÷ 3/2
[tex]= \frac{73}{4} * \frac{2}{3}\\\\=\frac{73}{2}*\frac{1}{3}\\\\=\frac{73*1}{2*3}\\\\=\frac{73}{6}\\\\=12\frac{1}{6} hours[/tex]
3) Third number = Sum of three numbers - Sum of two numbers
Sum of two numbers = [tex]8\frac{2}{3}+8\frac{1}{6}\\[/tex]
[tex]= \frac{26}{3} +\frac{49}{6}\\\\=\frac{26*2}{3*2}+\frac{49}{6}\\\\=\frac{52}{6}+\frac{49}{6}\\\\=\frac{52+49}{6}\\\\=\frac{101}{6}\\[/tex]
Third number = 22 8/15 - 101/6
[tex]= \frac{338}{15}- \frac{101}{6}\\\\= \frac{338*2}{15*2}- \frac{101*5}{6*5}\\\\= \frac{676}{30}- \frac{505}{30}\\\\= \frac{676-505}{30}\\\\= \frac{171}{30}\\\\=5 \frac{21}{30}\\\\= 5 \frac{7}{10}[/tex]

Which of these formulas models this arithmetic sequence?
8.7, 8.4, 8.1,7.8, 7.5,...
Answer:
The formula to model the arithmetic sequence will be:
[tex]a_n=-0.3n+9[/tex]
Step-by-step explanation:
Given the sequence
[tex]8.7,\:8.4,\:8.1,\:7.8,\:7.5,...[/tex]
An arithmetic sequence has a constant difference d and is defined by:
[tex]\:a_n=a_1+\left(n-1\right)d[/tex]
Computing the differences between all adjacent terms:
[tex]8.4-8.7=-0.3,\:\quad \:8.1-8.4=-0.3,\:\quad \:7.8-8.1=-0.3,\:\quad \:7.5-7.8=-0.3[/tex]
The difference between all adjacent terms is the same and equal to
[tex]d=-0.3[/tex]
The first element of the sequence is
[tex]a_1=8.7[/tex]
so
[tex]a_n=a_1+\left(n-1\right)d[/tex]
Therefore, the nth term is computed by:
[tex]a_n=-0.3\left(n-1\right)+8.7[/tex] ∵ [tex]d=-0.3[/tex]
[tex]a_n=-0.3n+9[/tex]
Therefore, the formula to model the arithmetic sequence will be:
[tex]a_n=-0.3n+9[/tex]
A rectangular is completety filled with dice.Each dice has volume of 2cm³.The length of the box is 5cm grater than its width and its height is 5cm.Suppose the box holds at most 150dice.What are the posibble dimensions of the box
Answer:
length = 10.64 cm, width = 5.64 cm, and height = 5 cm.
Step-by-step explanation:
Total volume of dice that filled the box = (150 x 2) cm³
= 300 cm³
Let the length, width and height of the box be represented by l, w and h respectively.
So that;
l = (w + 5) cm
w = w
h = 5 cm
volume of the box = length x width x height
= (w + 5) x w x 5
= (w + 5) x 5w
= 5[tex]w^{2}[/tex] + 25w
volume of the box = 5[tex]w^{2}[/tex] + 25w
Since the box was completely filled by 150 dice, then;
total volume of dice = volume of the box
300 = 5[tex]w^{2}[/tex] + 25w
5[tex]w^{2}[/tex] + 25w - 300 = 0
Divide through by 5 to have;
[tex]w^{2}[/tex] + 5w - 60 = 0
Applying the quadratic expression,
w = (-b ± [tex]\sqrt{b^{2} - 4ac}[/tex]) ÷ 2a
where: a = 1, b = 5 and c = -60
(-5 ± [tex]\sqrt{5^{2} - 4(1*-60)}[/tex] ) ÷ 2
(-5 ± [tex]\sqrt{265}[/tex]) ÷ 2
(-5 ± 16.28) ÷ 2
(-5 + 16.28) ÷ 2 OR (-5 - 16.28) ÷ 2
5.64 OR -10.64
Thus, w = 5.64 cm
So that, l = (w + 5) = 10.64 cm
The possible dimensions of the box are: length = 10.64 cm, width = 5.64 cm and height = 5 cm.

y is directly proportional to x
when y=30, x=6
Answer:
y = 5x
Step-by-step explanation:
Assuming you require the proportional equation
Given that y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition when y = 30, x = 6 , then
30 = 6k ( divide both sides by 6 )
5 = k
y = 5x ← equation of proportion

Answer:
7. y=42
8. y=58
If we could call on discord, zoom or anything like that i could easily explain. To type out the whole process would take all night
Step-by-step explanation:
Answer:
7. 42 degrees
8. 58 degrees
Step-by-step explanation:
Question 7
The three angles on the bottom line add up to 180.
65 + 31 + 2y = 180
2y = 84
So y = 42
Question 8
Let's start with the triangle with the 27 degree angle.
We have 27 + 90 + z = 180 (z is the top right angle)
z = 63 (which is also the bottom left angle of the triangle with the 32 degree angle).
63 + 32 + x = 180
x = 85 degrees
Now we look at the bottom polygon with the y degree angle we're trying to find.
We have one angle opposite x and another opposite z.
The angle opposite x + x = 180
The angle opposite x + 85 = 180
The angle opposite x = 95
The angle opposite z + z = 180
The angle opposite z + 63 = 180
The angle opposite z = 117
The sum of the interior angles of a polygon equals the number of sides less 2 * 180. We have four sides, so the interior angles add up to 360.
90 + 95 + 117 + y = 360
Therefore y = 58 degrees

The sum of three numbers is 19. The third number is eleven less than five times the second number. If the first number is quadruple the amount of the second number, what is the value of the third number? (may I have the equation please)
Answer:
third number = 4,
equation of y, y = 5x - 11
equation of n, n = 4x
equation of x, n + x + y =19
Step-by-step explanation:
so lets write evertything as a n equation. n + x + y =19. N is the first number, x is the second number, and y is the third number. We will write the equation for y as follows 5x - 11. N will be four times the second number, so 4x. If substitute the values for out equation for x we will find what x equals to. So (4x) + x + (5x - 11) = 19
10x = 30
x = 3.
Then you substiute the answer for x in the equation for y. This will get you 5(3) - 11
15 - 11
4 = third number
