Answer:
E. 1d+0.015d
G. 1.015d
Step-by-step explanation:
A is incorrect, as it only shows the 1.5% raise. B is incorrect, since that would be a 15% raise. C and D are incorrect because it's impossible to add a number with a variable to one without a variable. E is correct because it properly adds 100% (the amount he made without the raise) and 1.5% (the raise) together. F is incorrect because again, it adds 15%. G is correct because it is the total amount he makes, with the raise. H is incorrect because again, it adds 15%.

plz help me on this one its really hard :(
Answer:
It will be 63.9
Step-by-step explanation:
Trust me, I got it right
Answer:
63.6mm² (the last option)
Explanation:
the formula for calculating the area of a circle is πr², where r is the length of the radius.
in this case, we know that 9mm is the length of the diameter of the circle, so we can divide that by 2 to get 4.5mm for the length of the radius.
the question has instructed us to use 3.14 for π (pi), so we can substitute these values into the formula:
πr² = 3.14 × 4.5² = 63.585mm²
we can now round this to the nearest tenth to get 63.6mm², which would be the last option.
i hope this helps! :D
Three line segments have measures of 17 units, 11 units and 12 units. Will the segments make a triangle?
Answer:
Yes
Step-by-step explanation:
Yes, they will form a triangle. This is so because when testing for, we use the simple and logical analysis of
Adding up the two shorter sides > the third longest side.
In the example of the question we have here. The two short sides are 11 and 12 respectively. Adding them up together, we have
11 + 12 = 23
And the third longest side to be 17. Now, is 23 greater than 17 or not?
Of course it is, so yes, the sides will form a triangle.

The price of a technology stock was $9.84 yesterday. Today, the price fell to $9.73. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answer:
1.1 percent
Step-by-step explanation:
[(9.73 - 9.84) / 9.84 ] * 100 = -1.1 percent change = 1.1 percent decrease
Find the value of X. Please help ASAP!! I have no idea how to do this and I have to have it done soon!!
Answer:
[tex]x=\frac{3}{4}=0.75[/tex]
Step-by-step explanation:
From the shape of the quadrilateral, we can assume that it is a parallelogram. In a parallelogram, opposite sides are congruent and thus have the same length.
In this case, we are given that two opposite sides have lengths of [tex]4x+5[/tex] and [tex]8[/tex]. Therefore, since the quantities must be equal, we can write the following equation to solve for [tex]x[/tex]: [tex]4x+5=8[/tex]. Solving for [tex]x[/tex], we get:
[tex]4x+5=8[/tex]
[tex]4x=3[/tex] (Use the Subtraction Property of Equality to subtract [tex]5[/tex] from both sides of the equation, which isolates [tex]x[/tex])
[tex]x=\frac{3}{4} =0.75[/tex] (Use the Division Property of Equality to divide both sides of the equation by [tex]4[/tex] to get rid of [tex]x[/tex]'s coefficient)
Hope this helps!

Use what you know about the angle sum theorem for triangles and your algebra skills to solve for x and find the measure of all three angles:
Answer:
2x° = 45°, 3x° = 67.5°
Step-by-step explanation:
Sum of angles in a triangle = 180°
2x+3x+3x=180°
8x=180°
x=22.5°
2x=22.5°x2=45°
3x=22.5°x3=67.5°

Answer:
24 classes
Step-by-step explanation:
Let
x = number of classes
Devaughn is a member at the local gym = 120 + 5x
Jerome is not a member = 10x
Equate the total cost of both individuals
120 + 5x = 10x
120 = 10x - 5x
120 = 5x
x = 120/5
x = 24 classes
The total cost of Devaughn and the total cost of Jerome will be equal in 24 classes
A rectangular prism is 114 inch tall, 112 inch wide, and 2 inches long. How many unit cubes with side length of 14 inch does it take to fill the rectangular prism?
Answer: 9
Step-by-step explanation:
Given
The dimension of a rectangular prism is
[tex]L=2\ in[/tex]
[tex]W=112\ in.[/tex]
[tex]h=114\ in.[/tex]
Volume of Prism [tex]V=L\times W\times h[/tex]
[tex]\Rightarrow V=2\times 112\times 114=25,536\ in.^3[/tex]
The volume of the unit cube
[tex]\Rightarrow V_c=14\times 14\times 14=2744\ in.^3[/tex]
Suppose there are n unit cubes to fit in a rectangular prism
[tex]\Rightarrow n=\dfrac{V}{V_c}=\dfrac{25,536}{2744}=9.306\approx 9[/tex]

The population of fish in an aquarium can be modeled after exponential growth. If there
were originally 3 fish and after 6 weeks there were 31 fish, how many fish would there
be after 14 weeks?
321 fish
698 fish
452 fish
815 fish
Answer:
698 fishes
Step-by-step explanation:
Generally, we can represent an exponential growth function as;
y = a•(1 + r)^t
originally, there were 3 fishes
The original value in this case means a = 3
After 6 weeks, there were 31
31 in this case is y
r is the increase percentage or rate
t is the time
So, we have it that;
31 = 3•(1 + r)^6
31/3 = (1 + r)^6
10.33 = (1 + r)^6
ln 10.33 = 6 ln (1 + r)
ln 10.33/6 = ln (1 + r)
e^0.3892 = (1 + r)
1 + r = 1.476
r = 1.476-1
r = 0.476 or 47.6%
So the growth percentage or rate is 47.6%
For 14 weeks, we simply have the value of t as 14;
So ;
y = 3•(1 + 0.476)^14
y = 3(1.476)^14
y = 698 fishes

Solve for x.each figure is a parallelogram.show steps
Answer:
opposite sides of a parallelogram are equal
2x+15=x+15
2x-x=15-15
x=0
Answer:
x = 0
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, that is
ST = RU , substitute values
2x + 15 = x + 15 ( subtract x from both sides )
x + 15 = 15 ( subtract 15 from both sides )
x = 0

what is the answer (2x+1)(3x−4)=0
Answer:
x= 4/3
x= -1/2
Step-by-step explanation:
2x (3x-4) +1(3x-4) = 0
Distribute
6x^-8x +1(3x -4) = 0
Multiply by 1
6x^2 -8x +3x-4=0
Answer:
(2x + 1) ( 3x - 4) = 0
solve by factoring
2x + 1 = 0
2x = -1
divided by 2 on both sides
x = -1/2
3x - 4 = 0
3x = 4
divided by 3 on both sides
x = 4/3
x¹ = -1/2 , x² = 4/3 is the solution

Find the length of the missing side x ... please help me
Answer:
x = 10
Step-by-step explanation:
Use Pythagorean Theorem
c2 = a2 + b2
Here you must find the hypotenuse length (x) which is c in the equation. Thus substitute the values given into the equation:
c2 = 6^2 + 8^2
c2 = 100
Square root both sides so
c = 10
Thus length of x is 10

The wages w (in £) June earns is the number of hours she works n multiplied by her hourly rate r (in £ per hour). Enter a formula for June's wages and enter the wage she would earn if she worked 17 hours at a rate of £7.30 per hour
Answer:
Wages she earn = £124.1
Step-by-step explanation:
Given:
Number of hour work in June = 17 hour
Rate = £7.30 per hour
Find:
Wages she earn
Computation:
Wages she earn = Number of hour work in June x Rate
Wages she earn = 17 x £7.30
Wages she earn = £124.1

Answer:
Slope is -3
Equation is y = -3x + 2
Step-by-step explanation:
(0 , 2) and ( -1 , 5)
m= (y2-y1)/(x2-x1)
m= (5 - 2)/(-1 -0)
m= 3/-1
m= -3
y - y1 = m(x - x1)
y - 2 = -3(x - 0)
y - 2 = -3x + 0
y = -3x + 2
