Answer:
The number is 22
Step-by-step explanation:
let x = the number
[tex] \frac{1}{2} x + x - 8 = 25 \\ \frac{1}{2} x + x - 8 + 8 = 25 + 8 \\ \frac{1}{2} x + x = 33 \\ factor \: out\: x \: on \: the \: left \\ x( \frac{1}{2} + 1) = 33 \\ divide \: both \: sides \: by \: \frac{1}{2} + 1 \\ \frac{x( \frac{1}{2} + 1) }{ \frac{1}{2} + 1} = \frac{33}{ \frac{1}{2} + 1} \\ x = \frac{33}{ \frac{3}{2} } \\ x = \frac{66}{3} \\ x = 22[/tex]
let's factor out x from the left hand sid
The volume of this cone is 540π. Work out the height,h, of the cone, radius=9cm
Answer:
h = 20
Step-by-step explanation:
540π = 1/3 . h . π . 9^2
get rid of π
540 = 1/3 . h . 9^2
multiply by 3 to get rid of 1/3
3 . 540 = h . 9^2
1620 = h . 81
divide by 81
1620/81 = h
20 = h

10. Determine if the equation x - y = 1 defines y as a function of x.
Answer:
No.
Step-by-step explanation:
First solve for y:-
x - y^4 = 1
y^4 = x - 1
y = +/- (x - 1)^(1/4)
This is a one-to-many relation . For a given value of y there 2 values of x.
So this is NOT a function.

Step-by-step explanation:
x+15=180
Answer:
[tex] \\ \boxed{ \sf{x = 165 \degree}}[/tex]
Step-by-step explanation:
We know that a straight line has an angle of 180°.
Therefore,
x+15 = 180x = 180 -15x = 165Thus, the value of x is 165°.

Place the following steps in order to describe how to solve the following equation: 2(2x+3)-2=52(2x+3)−2=5
Answer:
frist parentheses then subtract
The solution of equation 2(2x+3)-2 = 52(2x+3)−2 = 5 is x = -29/20.
What is PEMDAS?The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.
The given equation:
2(2x+3)-2 = 52(2x+3)−2 = 5
Simplifying,
2(2x+3)-2 = 52(2x+3)−2 - 5
Using PEMDAS,
first, we solve the parentheses
4x+6 - 2 = 104x + 156 - 2 - 5
4x+4 = 104x + 149
104x - 4x = 4 - 149
100x = -145
x = -145/100
x = -29/20
Therefore, the value of x is -29/20.

Step-by-step explanation:
Given PQ = 24
PS = 19
PR = 42
TQ = 10
m<PQR = 106°
m<QSR = 49°
m<PRS = 35°
find m<QRS, m<PQS, m<RPS and m<PSQ
The shape PQRS is a parallelogram
The measure of angle QRS is 70 degreesThe measure of angle PQS is 53 degreesThe measure of angle RPS is 35 degreesThe measure of angle PSQ is 53 degreesThe given parameters are:
[tex]\mathbf{\angle PQR = 106}[/tex]
[tex]\mathbf{\angle QSR = 49}[/tex]
[tex]\mathbf{\angle PRS = 35}[/tex]
(a) Find QRS
This is calculated as:
[tex]\mathbf{\angle QRS = 2 \times \angle PRS }[/tex]
So, we have:
[tex]\mathbf{\angle QRS = 2 \times 35}[/tex]
[tex]\mathbf{\angle QRS = 70}[/tex]
Hence, the measure of angle QRS is 70 degrees
(b) Find PQS
This is calculated as:
[tex]\mathbf{\angle PQS = \frac 12 \times \angle PQR }[/tex]
So, we have:
[tex]\mathbf{\angle PQS = \frac 12 \times 106}[/tex]
[tex]\mathbf{\angle PQS = 53}[/tex]
Hence, the measure of angle PQS is 53 degrees
(c) Find RPS
This is calculated as:
[tex]\mathbf{\angle RPS = \angle PRQ }[/tex]
Where:
[tex]\mathbf{\angle PRQ = \angle PRS = 35}[/tex]
So, we have:
[tex]\mathbf{\angle RPS = 35}[/tex]
Hence, the measure of angle RPS is 35 degrees
(d) Find PSQ
This is calculated as:
[tex]\mathbf{\angle PSQ =\frac 12 \times \angle PQR }[/tex]
Where:
[tex]\mathbf{\angle PSQ =\frac 12 \times \angle 106}[/tex]
So, we have:
[tex]\mathbf{\angle PSQ =53}[/tex]
Hence, the measure of angle PSQ is 53 degrees

The broccoli farmer notices that his pre-flowering crop is being attacked by caterpillars. He was advised to use a particular insecticide at the rate of 5 milliliters per gallon of water. The farmer finds that a 4 gallon can of water covers an area of 30m². The chemical in question comes in 1500ml bottles and costs $3,500.
FIND:
a) How many gallons of water would cover his 2.6-hectare area?
b) How many pesticides is needed to adequately spray the field?
c) What would be his total cost for whole bottles of insecticide needed?
pls help
Answer:
a) 3,467 gallons of water
b) 17,335 ml of insecticide = 12 bottles
c) $ 42,000
Step-by-step explanation:
1 gal. Water = 3785.412 ml
1 hectare = 10,000 m^2
2.6 hectare = 2.5 x 10.000 m^2 = 26,000 m^2
(a) 4 gal. water cover 30m^2
X gal water cover 26,000 m^2
(4 x 26,000)/30 = 3,467 gal of water
(b) 5 ml per 1 gal of water
X ml per 3,467 gal of water
(5 x 3,467) = 17,335 ml of insecticide
Bottle of insecticide = 1,500 ml of insecticide in each bottle.
17,335/1,500 = 12 bottles of insecticide
(c) 12 x $3,500 = $ 42,000

C. x = 5 and y = -13
D. x = -9 and y = 4
Answer: C. x = 5 and y = -13
I hope this helps.
The value of x is 5 and the value of y is -13 which satisfies the equation. The correct option is C.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
The given equation is,
( x + yi ) + ( 4 + 9i ) = 9 - 4i
The points are x= 5 and y = -13,
( x + yi ) + ( 4 + 9i ) = 9 - 4i
( 5 -13i ) + ( 4 + 9i ) = 9 - 4i
5 + 4 -13i+9i = 9-4i
9-4i = 9 - 4i
Therefore, the value of x is 5 and the value of y is -13 which satisfies the equation. The correct option is C.

Step-by-step explanation:
You're looking for rational numbers that are also integers, but because (as the figure shows) ALL integers are already rational, you only have to worry about the integer part. An integer is a whole number, positive or negative. So, you need to simplify each element of each set (the numbers inside the curly braces) to see if they're whole.
A - The square root of 100 is just 10 or -10, divided by -2 is -5 or 5. 4, -2, 5, and -5 are all integers.
B - Wrong because 4/3 is not a whole number
C - 16/4 is just 4, and the square root of 49 is 7 or -7. 4, -6, 2, 7, & -7 are all integers.
D - Wrong because 27/2 is not a whole number
E - Wrong because 0.2 is not a whole number
