Sylvie needs $110 for a concert ticket. She already has $16 and she can earn the rest by working 10 hours at her job. If h represents her hourly earnings, which of the following equations can be solved to find Sylvie’s hourly earnings?
Answer:9.4$ a hour
Step-by-step explanation:
110 - 16 = 94
94 / 10 = 9.4
she makes 9.4$ a hour
<!> Brainliest is appreciated! <!>
Answer:
10h - 16
Step-by-step explanation:
She needs $110 so,
110 = however much she's getting an hour times 10 hours, minus 16 because she already has $16
110 = 10x - 16

Soccer team has 10 players in a tournament there are seven teams and two players on each team drop out how many are there left
Answer:
1 team = 10 players
7 teams = 7×10 players
= 70 players
drop out players:
1 team = 2 players
7 teams = 2×7
= 14 players
how many left ?
= total players - drop out players
= 70 - 14
= 56 players

between which to whole numbers does the square root of 119 lie?
Answer:
10 and 11
Step-by-step explanation:
[tex]1^2, 2^2, 3^2, 4^2, 5^2, 6^2, 7^2, 8^2, 9^2, 10^2, 11^2\\1, 4, 9, 16, 25, 36,49,64,81,100,121[/tex]
The [tex]\sqrt{119}[/tex] lies between whole number 10 and 11 since it lies between 100-121 which square rooted, is 10 and 11.
Answer:
Between 10 and 11
Step-by-step explanation:
10 squared (10 x 10) is 100 and 11 squared (11 x 11) is 121, the number 119 is between 100 and 121, therefore, the the square root of 119 lies between 10 and 11.
PLEASE HELP NOW!!!!!! I WILL GIVE BRAINLIEST!!!!!!!! How many 4-digit numbers divisible by 5, all of the digits of which are even, are there?
A number is divisible by 5 if the digit in the units or ones place is either 0 or 5. We want all digits to be even, so we throw out 5 as a candidate digit.
We're considering all numbers between 1000 and 9999, of which there are 9000. Numbers in this range can have any of the digits 0-9 in the tens and hundreds place, and any of 1-9 in the thousands place.
We also want all digits to be even, which means we can pull from the numbers {0, 2, 4, 6, 8} in the hundreds and tens places, and {2, 4, 6, 8} in the thousands place.
So there are 4*5*5*1 = 100 numbers in this range that are divisible by 5.

Trigonometric ratio
Trigonometric ratio is used to show the relationship between the angles and sides of a right angled triangle.
Given triangle DEF:
DE = EF (Hence it is an isosceles triangle)
∠F = ∠D ( Isosceles triangle)
cos(F) = cos(D) = 5 / 5√2 = 1/√2
sin(F) = sin(D) = 5 / 5√2 = 1/√2
tan(F) = tan(D) = 5 / 5 = 1
In right angled triangle DEF, cos(F) = cos(D) = 1/√2, sin(F) = sin(D) = 1/√2 and tan(F) = tan(D) = 1

As an estimation we are told £3 is €4. Convert £73.50 to euros.
Answer:
£73.5 = € 98
Step-by-step explanation:
Let's use the unitary method
=> £3 = €4
So,
£1 = €4/3
Multiplying both sides by 73.5
£73.5 = € 98
Answer:
€98
Step-by-step explanation:
£3 = €4
£73.5 = €x
Let the unknown euros be x.
Cross multiply
3 × x = 4 × 73.5
3 × x = 294
Divide both sides by 3.
x = 294/3
x = 98

Which equation is represented by the table?
O A. y = 2x + 1
OB. y = 3x + 2
O C. y = 4x - 1
OD.y = 5x - 3
=================================================
Explanation:
Each time x goes up by 1, the y value goes up by 4. The slope must be 4/1 = 4.
You can use the slope formula, picking any two points from the table, to get the same result. Let's say we used the first two rows
m = (y2 - y1)/(x2 - x1)
m = (7-3)/(2-1)
m = 4/1
m = 4
So the answer must be y = 4x-1 as its the only equation with a slope of 4.
To find the y intercept, we plug m = 4 and (x,y) = (1,3) into y = mx+b to solve for b. You can use any (x,y) pair from the table. I picked the first row
y = mx+b
3 = 4(1)+b
3 = 4+b
3-4 = b
-1 = b
b = -1
Since m = 4 and b = -1, we go from y = mx+b to y = 4x+(-1) or y = 4x-1
Find the slope then the y - intercept of the line. Y = -5/2x + 3
Answer:
m = -5/2
b = 3
Step-by-step explanation:
The equation is in y = mx +b form where m is the slope and b is the y-intercept. This means that the slope is -5/2 and the y-intercept is 3.

Answer:
7 cm
Step-by-step explanation:
The area of a right triangle is given by
A = 1/2 bh
21 = 1/2 y* 6
21 = 3y
Divide each side by 3
21/3 = 3y/3
7 = y
The base is 7 cm
Area formula: A = bh/2
We have a height of 6, a base of y, and a area of 21.
Fill in and solve:
21 = y * 6 / 2
21 = 6y/2
21 = 3y
7 = y
Therefore, the base is 7

The endpoints of JK are J(–25, 10) and K(5, –20). What is the y-coordinate of point L, which divides JK into a 7:3 ratio?
Answer:
-11
Step-by-step explanation:
You need to find the difference in y-coordinates and divide that difference into a 7:3 ratio. Then you add that to the y-coordinate of point J.
Difference in y:
-20 - 10 = -30
7 + 3 = 10
7/10 * (-30) = -21
Add -21 to 10:
10 + (-21) = -11
The y-coordinate is -11.

13 At the beginning of 2009, Mr Veale bought a company.
The value of the company was £50 000
Each year the value of the company increased by 2%.
(a) Calculate the value of the company at the beginning of 2017
Give your answer correct to the nearest £100
Answer:
£58,800
Step-by-step explanation:
The answer can be calculated using
FV=p(1+r/n)^nt
P=£50,000
r=2%=0.02
n=12
t=2009 to 2017=8 years
FV=p(1+r/n)^nt
=50,000(1+0.02/12)^12*8
=50,000(1+0.0017)^96
=50,000(1.0017)^96
=50,000(1.1771)
=58,855
FV=58,855
To the nearest £100=£58,800

Then 5, then 6 and finally 7
Sides of the rectangle:
4+4+5=13
6+7= 13
7+4=11
5+6=11
7 units are the side length of the largest square.
What is a square?A square is a regular quadrilateral in Euclidean geometry, which means that it has four equal sides and four equal angles. It can alternatively be explained as a rectangle with two neighboring sides that are of equal length.
Given :
Let x be the side length of the second-smallest square.
Since the following size is square and 2 taller than the "x" square, its side length is (x+2).
This indicates that the bottom is longer (2x+x+2).
This can be used to discover expressions for the rectangle's top, left, and right sides. You can solve for x and consequently both dimensions because the top and bottom are identical in length.
Therefore, 7 units are the side length of the largest square.

a. f(-8)
b. 9(-6)
c. h(9)
Answer:
see below
Step-by-step explanation:
f(x) = 5x^3 +1, g(x) = – 2x^2, and h(x) = - 4x^2 – 2x +5
f(-8) = 5(-8)^3 +1 = 5 *(-512) +1 =-2560+1 =-2559
g( -6) = -2 ( -6) ^2 = -2 ( 36) = -72
h(9) = -4( 9)^2 -2(9) +5 = -4 ( 81) -18+5 = -324-18+5=-337
mr smith owns a lot of valued at 12000. It is assessed at 80% of it value. how much tax does he pay if the tax rate if 1.5% of the assessed value.
Find the assessed amount:
12000 x 0.80 = 9600
Multiply the assessed amount by tax rate:
9600 x 0.015 = 144
He pay $144
The amount of tax Mr smith pays if the tax rate is 1.5% of the assessed value will be $144.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage has numerous applications in the real life for example in school marks, salary deduction, and all accounting.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 1%=1/100=0.01.
Value of lot $12000
assessed amount:
12000 x 0.80 = $9600
The tax rate is 1.5% so the tax of the assessed amount will be
$9600 × 0.015 = $144 hence it will be the tax amount that Mr smith needs to pay.

No solutionStep-by-step explanation:
7( r - 2 ) - 9(r - 1) = 3 ( 5 - r ) + ( r - 8 )
Distribute 7 through the parentheses
7r - 14 - 9(r - 1 ) = 3( 5 - r ) + ( r - 8)
Distribute -9 though the parantheses
7r - 14 - 9r + 9 = 3(5 - r ) + ( r - 8)
Distribute 3 through the parantheses
7r - 14 - 9r + 9 = 15 - 3r + r - 8
When there is (+) in front of an expression in parentheses, the expression remains the same
7r - 14 - 9r + 9 = 15 - 3r + r - 8
Collect like terms
7r - 9r - 14 + 9 = 15 - 3r + r - 8
-2r - 14 + 9 = 15 - 3r + r - 8
Calculate
-2r- 5 = 15 - 3r + r - 8
Subtract the number
-2r - 5 = 7 - 3r + r
Collect like terms
-2r - 5 = 7 - 2r
Cancel equal terms on both sides of the equation
- 5 = 7
The statement is False for any value of X.
Hence, there is no solution.
