Step-by-step explanation:
The answer is C
We can easily eliminate B and D since Ms. Macdonald isn't starting with 3 rabbits.
We can also eliminate choice A, because 5 to the 3rd power isn't 15.
5 to the 3rd power is 125, therefore the choice is C
Carl and Derrick are part-time employees. They are paid different hourly rates. One week, Carl worked for 15 hours and Derrick worked for 20 hours. Their combined pay was $640. The next week, Carl worked 20 hours and Derrick worked 25 hours. Their combined pay was $820. What is Carl's hourly pay rate?
Answer:
Carl's hourly pay rate is $16
Step-by-step explanation:
Let x is the hourly rate of Carl and y is the hourly rate of Derrick
∵ Carl's hourly rate is $x
∵ Derrick's hourly rate is $y
∵ Carl worked for 15 hours and Derrick worked for 20 hours
∴ Their combined pay was 15x + 20y
∵ Their combined pay was $640
→ Equate the value of the combined pay
∴ 15x + 20y = 640 ⇒ (1)
∵ The next week, Carl worked 20 hours and Derrick worked 25 hours
∴ Their combined pay was 20x + 25 y
∵ Their combined pay was $820
→ Equate the value of the combined pay
∴ 20x + 25y = 820 ⇒ (2)
Now we have a system of equations to solve it
→ Multiply equation (1) by 5 and equation (2) by -4
∵ 5(15x) + 5(20y) = 5(640)
∴ 75x + 100y = 3200 ⇒ (3)
∵ -4(20x) + -4(25y) = -4(820)
∴ -80x - 100y = -3280 ⇒ (4)
→ Add equations (3) and (4)
∵ (75x + -80x) + (100y + -100y) = (3200 + -3280)
∴ -5x + 0 = -80
∴ -5x = -80
→ Divide both sides by -5 to find x
∴ x = 16
∴ Carl's hourly pay rate is $16

Prove that: (Sec A- cosec A)(1+ tan A+cot A) = tan A× sec A - cot A × cosec A
Answer:
Step-by-step explanation:
[tex](sec A-cosecA)(1+tanA+cotA)=tanAsecA-cotAcosecA[/tex]
we take the LHS so here goes,
[tex](sec A-cosecA)(1+tanA+cotA)=tanAsecA-cotAcosecA\\(\frac{1}{cosA} -\frac{1}{sinA})(1+\frac{sinA}{cosA}+\frac{cosA}{sinA})\\\\(\frac{sinA-cosA}{sinAcosA})(\frac{sinAcosA+sin^2A+cos^2A}{sinAcosA})\\[/tex]
since , [tex]sin^2A+cos^2A=1[/tex]
the identity becomes,
[tex](\frac{sinA-cosA}{sinAcosA})(\frac{1+sinAcosA}{sinAcosA})\\\\(\frac{sinA+sin^2AcosA-cosA-cos^2AsinA}{sin^2Acos^2A})\\\\[/tex]
now, we know,
[tex]sin^2A=1-cos^2A[/tex] and [tex]cos^2A=1-sin^2A[/tex]
the identity becomes,
[tex](\frac{sinA+(1-cos^2A)cosA-cosA-(1-sin^2A)sinA}{sin^2Acos^2A} )\\\\[/tex]
[tex](\frac{sinA+cosA-cos^3A-cosA-sinA+sin^3A}{sin^2Acos^2A})[/tex]
sin A and cos A cancel out it becomes zero
[tex]\frac{sin^3A-cos^3A}{sin^2Acos^2A} \\\\[/tex]
Splitting the denominator the identity becomes
[tex]\frac{sin^3A}{sin^2Acos^2A}-\frac{cos^3A}{sin^2Acos^2A} \\\\\frac{sinA}{cos^2A} - \frac{cosA}{sin^2A} \\\\\frac{sinA}{cosA}(\frac{1}{cosA})-\frac{cosA}{sinA}(\frac{1}{sinA})\\\\[/tex]
Hence,
[tex]tanAsecA-cotAcosecA[/tex]

Construct an equilateral triangle of side 7cm and construct circumcircle.
Can anyone help me with this , I have to sumbit my PROJECT.
THanks
Answer:
To do this, all you need is to draw triangle with each side being 7 cm, and a circle that intersects all three of its corners.
Step-by-step explanation:
With a ruler and a pencil, draw a 7cm line.With a compass set to a radius of 7cm draw an arc centered around the right end of the line.With the same compass, still at 7cm, draw an arc centered around the left end of the line.These two arcs will intersect on either side of the line (you only need one side, so you only need a small arc in the right place, roughly where you think the third point if the triangle is.Where those arcs intersect is the third point on your triangle. Mark that, and then trace two lines from that point to either end of the line segment you started with.You now have an equilateral triangle with 7cm sides. Next you need to draw the circle
Measure the halfway point on two of your three lines.Draw a line from that each of those halfway points to the opposite corner. The new lines you're drawing will be perpendicular to the edge your measuring against.You have now drawn two line segments, and they intersect in the center of the circle. Now take your compass and set its radius to the distance from that center point to one of the three corner points.Centered on that middle point, trace a circle with the selected radius.And you're done!
2(x + 14) = 40
Can you please do all the steps of solving this?
Ex:
8(7+1)3=192
8 x (7+1) x 3
8
8x8=64
64x3=192
total=192
Given:
The equation is
[tex]2(x+14)=40[/tex]
To find:
The solution of the given equation.
Solution:
We have,
[tex]2(x+14)=40[/tex]
Using distributive property, we get
[tex]2(x)+2(14)=40[/tex]
[tex]2x+28=40[/tex]
Subtracting 28 from both sides.
[tex]2x=40-28[/tex]
[tex]2x=12[/tex]
On dividing both sides by 2, we get
[tex]x=6[/tex]
Therefore, the solution of the given equation is x = 6.

The diagram represents a reduction of a triangle by using a scale factor of 0.8.
What is the height of the reduced triangle?
A) 4.0 inches
B) 4.8 inches
C) 5.2 inches
D) 7.5 inches
Answer:
B 4.8 inches
Step-by-step explanation:
The scale factors are used to convert a figure into another one with similar characteristics but different lengths, in this example is a triangle, and in order to calculate the measure of the height you just have to multiply the original height by the scale factor:

Is it possible to construct a quadrilateral from any 4 given measurements of its sides? State a reason for your answer.
Answer:
It is NOT possible to construct a quadrilateral from any 4 given measurements of its sides.
Step-by-step explanation:
We know that the Quadrilateral is a 2D closed figure with four sides.The Quadrilateral has four vertices or corners.We are asked to tell whether it is possible to construct a quadrilateral from any 4 given measurements of its sides.
Well, in order to construct a quadrilateral from any 4 given measurements of its sides, we need at least five dimensions.
With only 4 given measurements of its sides, we won't know any of its angles.
Thus, it is NOT possible to construct a quadrilateral from any 4 given measurements of its sides.

Step-by-step explanation:
16 / 3/4= 16(keep) x (change from dividing to multiplying) 4/3 (flip)
15 / 3/5= 15 (keep) x (change from dividing to multiplying) 5/3 (flip)
12 / 4= 12 (keep) x (change from dividing to multiplying) 1/4 (flip)
so you keep the first number change the sign like for example if its dividing you'll change it to multiplying and if its adding you'll change it to subtracting then flip the fraction

Find the Valur that Would make the graphs parallel... Its alegebra please help quick i need help!
Answer:
k=8
Step-by-step explanation:
For 2 lines to be parallel, they must have the same slope. First, let's isolate y.
5y=2x+2
y=2/5x+2/5
Now, in our second equation, we must make it so that the slope is 2/5.
5(4)=20
2(4)=k
k=8
y=8/20x+10
If you simplify that, then the slope will be 2/5.

Jane said that 6(64) = 6(50) + 6(14). Is she correct? Use the Distributive Property to explain your answer.
Answer:
Yes.
Step-by-step explanation:
6(64) = 6(50+14)
Using the Distributive Property, 6 needs to be multiplied by both 50 and 14.
6(50+14) = 6(50) + 6(14)
Thus, Jane is correct.
In 1867, the United States purchased Alaska from Russia. Alaska is about 5.9 × 105 square miles. The United States paid about $12.20 per square mile. Approximately how much did the United States pay Russia for Alaska? Complete the steps to answer the question. 1. Write the expression: (5.9 × 105)(12.2) 2. Multiply the decimal values: × 105 3. Write in scientific notation: × The United States paid Russia approximately for Alaska.
Answer:
$7.198 * 10^6
Step-by-step explanation:
Given that :
Total Area of Alaska = 5.9 * 10^5 mi²
Cost of Alaska per square mile = $12.20
Total amount paid to purchase Alaska:
(Total area in square miles * Cost per square mile)
(5.9 × 10^5) * $12.20
(5.9*12.20) * 10^5
71.98 * 10^5 dollars
= $7.198 * 10^6
Hence, amount the United States paid Russia for the purchase of Alaska is approximately $7.198 * 10^6
Answer:
1. Write the expression: (5.9 × 105)(12.2)
2. Multiply the decimal values:
✔ 71.98
× 105
3. Write in scientific notation:
✔ 7.198
×
✔ 10 to the sixth power
The United States paid Russia approximately
✔ $7,200,000
for Alaska.
