[tex] \boxed{\stackrel{\Large\frown}{PQS}\:= 222°} [/tex]
Explanation:
Since [tex] \overline{PR} [/tex] is a diameter, arc [tex] \stackrel{\Large\frown}{PQR}\:= 180°. [/tex]
Given that [tex] \angle{SUR} = 42°[/tex] is a subtended central angle by two diameters,
[tex] \stackrel{\large\frown}{RS} \:= 42° [/tex].
Using the rule of arcs, [tex] \stackrel{\Large\frown}{PQR} + \stackrel{\large\frown}{RS} \: = \: \stackrel{\Large\frown}{PQS} [/tex] →
[tex] 180° + \: 42° = \: \stackrel{\Large\frown}{PQS} [/tex]
[tex] 222° = \: \stackrel{\Large\frown}{PQS} [/tex]
[tex] \stackrel{\Large\frown}{PQS} \: = \: 222° [/tex]

Answers
9514 1404 393
Answer:
(x, y) = (4, 10)
Step-by-step explanation:
The coefficients of y are opposites, so the y-terms can be eliminated by adding the equations.
(8x -5y) +(2x +5y) = (-18) +(58)
10x = 40 . . . . . . simplify
x = 4 . . . . . . . . . divide by 10
Substituting this into the second equation gives ...
2(4) +5y = 58
5y = 50 . . . . . . . . subtract 8
y = 10 . . . . . . . . . .divide by 5
The solution is (x, y) = (4, 10).

Camille is attending a fundraiser. She pays for her admission and buys several raffle tickets.
The function S = 5r + 13 represents the total amount of money she paid, S.
and the number of tickets she bought, r. Which is a correct statement?
Camille paid total of $18 at the fundraiser.
The admission was $5.
Camille bought 13 tickets.
The admission was $13.
Answers
Answer: S=5r+85 i think try it out
Step-by-step explanation:
Answer:
The second statement.
Step-by-step explanation:

The hanger image represents a balanced equation (look at picture)
Answers
Answer:
A) [tex]27 = b + 9[/tex]
[tex]b=18[/tex]
Step-by-step explanation:
When given a balanced scale (represented by a hanger in this image), the sum of the values on one side equals the value on the other side. Thus, the equation that this hanger represents is the following:
[tex]27 = b + 9[/tex]
Use inverse operations to solve this equation,
[tex]27 = b + 9[/tex]
[tex]-9[/tex]

A student in a chemistry lab has access to two acid solution .The first solution is 20% acid and the second is 45% acid .(the percentage are by volume). How many milliliters of each solution the student mix together to obtain 100 ml of a 30% acid solution?
Answers
Answer:
x = 20% acid = 60 ml
y = 45% acid = 40 ml
Step-by-step explanation:
Let
x = 20% acid
y = 45% acid
x + y = 100 (1)
.20x + .45y = .3 ×100
.20x + .45y = 30 (2)
From (1)
x + y = 100 (1)
x = 100 - y
Substitute x = 100 - y into (2)
.20x + .45y = 30
.20(100 - y) + .45y = 30
20 - .20y + .45y = 30
- .20y + .45y = 30 - 20
.25y = 10
y = 10/.25
y = 40 ml
Substitute y = 40 into (1)
x + y = 100
x + 40 = 100
x = 100 - 40
x = 60 ml
x = 20% acid = 60 ml
y = 45% acid = 40 ml

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
x² + 5x = 0 be equation (1)
Now , on simplifying the equation , we get
On factorizing the equation , we get
Taking the common factor x ,
x ( x + 5 ) = 0
Now , x can take 2 values which will satisfy the given equation
when x = 0 or ( x + 5 ) = 0
when x = 0
Substitute the value of x in the equation , we get
0 ( 0 + 5 ) = 0
0 = 0
The equation is true when x = 0
And ,
when ( x + 5 ) = 0
Subtracting 5 on both sides of the equation , we get
x = -5
when x = -5
-5 ( -5 + 5 ) = 0
-5 x 0 = 0
0 = 0
The equation is true when x = -5
Hence , the solution is 0 , -5

Se 15% de um rebanho bovino são bois e o restante são vacas, qual é o total de cabeças desse rebanho, se há 17.000 vacas?
Answers
Responder:
20.000
Explicação passo a passo:
Dado que:
Porcentagem de bois no rebanho = 15%
Percentagem de vacas = (100 - 15)% = 85%
Número de vacas = 17.000
Por isso,
85% = 17.000
15% = x
Multiplicação cruzada
0,85x = 17.000 * 0,15
0,85x = 2550
x = 2550 / 0,85
x = 3000
Número de bois no rebanho = 3000
Portanto, número total de gado no rebanho =
3000 + 17000 = 20.000
"sports discount" has uniforms for 68$. They are offering a 20% discount on each uniform, and a 7 percent sales tax will be applied to the discount price. What would be the final cost for eight uniforms after the discount and sales tax
Answers
Answer:
58.208 times 8 equals 465.664 rounded down to 465.66
Step-by-step explanation:
Answer:
$465.66
Step-by-step explanation:
First, we are buying 8 uniforms. Therefore, the total price on a normal day would be 8x68 = $544
However, on this day, there is a 20% discount. In other words, we are only paying 80% of the original price as percentages are always out of 100.
The price after the sports discount will be 544x0.8 = $435.2
On top of this, we have to pay a sales tax of 7 percent. The 7 percent is an additional cost to the discounted price of 435.2, hence we add 0.07 (7 percent in decimals) onto 1 (100% in decimals).
This gives us 435.2 x ( 1 + 0.07 ) = 465.664.
Because currency is to 2 decimal points (1 cent), the final answer will be 465.66, or 465 dollars and 66 cents.

Answers
Answer:
The correct angle is 45.3°
Step-by-step explanation:
Since the opposite side of the angle is 32 feet, and the hypotenuse of the right triangle is 45 feet, you would know that the sine of x° is equivalent to [tex]\frac{32}{45}[/tex]. To find the value of x, take the arcsin of both sides and you'll get that [tex]x = arcsin(\frac{32}{45})[/tex] ⇒ [tex]x[/tex] ≈ 45.3°.
