sin 70 in surf form
Step-by-step explanation:
Calculate sin(70)°
Determine quadrant:
Since our angle is between 0 and 90 degrees, it is located in Quadrant I In the first quadrant, the values for sin, cos and tan are positive.
Determine angle type:
70 is an acute angle since it is less than 90°
sin(70) = 0.93969262030844
Write sin(70) in terms of cos
Since 70° is less than 90,
we can express this in terms of a cofunction
sin(θ) = cos(90 - θ)
sin(70) = cos(90 - 70)
sin(70) = cos(20)

Grapes cost $1.87 per pound. How much would it cost for 4.25 pounds of grapes?
Answer:
7.95$
Step-by-step explanation:
1.87 $ per 1 lb
1.87 * 4.25 = 7.95$
Answer:
$7.95 for 4.25 lbs. of grapes
Step-by-step explanation:
so your going to multiply $1.87 by 4.25 to get the total amount of money needing to be paid in or der to buy the 4.25 lbs. of grapes:
$1.87 * 4.25 = 7.9475
now turning it into money by rounding to the hundredths place:
7.9475 = $7.95
So you would have to pay $7.95 for 4.25 lbs. of grapes but logically you would bring 8 dollars to buy it, but down to the cents it would be $7.95.
whats the solution
Answer:
Step-by-step explanation:
To find the center and the radius, we need to put the equation in the (x-a)^2+(y-b)^2=r^2 [a is the x-coordinate, b is the y-coordinate, and r is the radius].
(x+6)^2+(y+7)^2 - 36 - 49 + 69 = 0
(x+6)^2+(y+7)^2 - 16 = 0
(x+6)^2+(y+7)^2 = 16
(x+6)^2+(y+7)^2 = 4^2
The center is (-6,-7) and the radius is 4.

Solve-1 + 8 =
10 - 3a.
Answer:
a = 1
Step-by-step explanation:
Original Equation:
-1 + 8 = 10 - 3a
Add 1 to both sides
8 = 11 - 3a
Subtract 11 from both sides
-3 = -3a
Divide both sides by -3
a = 1
Hope this helps :)

Gabe is analyzing the plane ticket prices over the years. Comparing the cost of a plane ticket this year to last year, ticket prices are 12% higer than they were last year. Create an expression that represents the difference between this year and last year
Answer:
The difference in prices is 0.12x where x is the last year’s price
Step-by-step explanation:
Here, we want to create an expression
Let the price last year be x
12% more this year mean;
x + 12% of x
= x + 0.12x = 1.12x
So the difference between this year and last year will be;
1.12x - x = 0.12x

Annabelle has $600 in a savings account that earns 2% simple interest for 6 years. Caroline has $400 in a savings account that earns 3% simple interest for 6 years. Whose account will have more money in it after the 6 years? How much more money will they have in their account?
Answer:
Step-by-step explanation:
Using the formula for calculating Amount;
Amount = Principal + Interest
Interest = Principal * Rate * time/100
For Annabelle:
Interest = 600*2*6/100
Interest = 6*2*6
Interest = $72
Amount after 6 years = $600 + $72 = $672
For Caroline:
Interest = 400*3*6/100
Interest = 4*3*6
Interest = $72
Amount after 6years = $400+$72 = $472
Hence Annabelle account will have more in it after 6 years.
Taking the difference in their amount = $672-$472 = $200
Hence Annabelle will have $200 more than Caroline in her account after 6 years
Choose all the expressions that are equal to 0.8 × 0.03.
A. 8100×3100
B. 3100×810
C. 80100×3100
D. 310×8010
E. 810×3100
Answer: 8/10 × 3/100
3/100 × 8/10
Step-by-step explanation:
To be able to solve this question, we need to convert the decimals to Fractions. After they've bee converted to Fractions, we can then look at the options given and see the correct option.
0.8 will be 8/10 when converted to a fraction while 0.03 will be 3/100. Therefore, the correct option will be:
= 8/10 × 3/100 or 3/100 × 8/10.
Therefore, options B and E are correct.

1. 2x+5(6x-9)=179
2. -40=6x-5(-4x-18)
solve for X
Answer:
1. x = 7
2. x = -5
Step-by-step explanation:
1. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: 2*x+5*(6*x-9)-(179)=0
Pull out like factors 6x - 9 = 3 • (2x - 3)
(2x + 15 • (2x - 3)) - 179 = 0
Pull out like factors: 32x - 224 = 32 • (x - 7)
Solve: x-7 = 0
Add 7 to both sides of the equation = 7
2. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: -40-(6*x-5*(-4*x-18))=0
Pull out like factors: -4x - 18 = -2 • (2x + 9)
-40 - (6x - -10 • (2x + 9)) = 0
Pull out like factors: -26x - 130 = -26 • (x + 5)
-26 • (x + 5) = 0
Solve: x+5 = 0
Subtract 5 from both sides of the equation: x = -5
Hope this helps! Please mark as brainliest.
Thanks!

Which graph shape represents the polar curve r = 1 + 4sin(θ)?
a cardioid
a rose curve
a limaçon with an inner loop
a limaçon without an inner loop
Answer:
A cardioid
Step-by-step explanation:
A cardioid is a curve in the shape of a heart traced by a point on the circumference of a circle as it rolls around a fixed circle of the same radius.
The equation of vertical cardioid is [tex]r=a[/tex] ± [tex]a\sin \theta[/tex]
Given the polar curve is [tex]r=[/tex] [tex]1+[/tex] 4 [tex]\sin \theta[/tex]
This is an equation of vertical cardioid.
So, it represents a cardioid.
Answer:
C - a limaçon with an inner loop
Step-by-step explanation:
If you have a graphing calculator, use it to plug in the equation.
Based on what you have learned, you will recognize the graph is C

Answer:
40
Step-by-step explanation:
A kilometre is 1000 metres. 1000 / 25 = 40. So forty basketball courts would be approximately 1 km if lined up end to end.
The answer is 40 because 1 kilometer divided by 25 meters would be 40 and each court is 25 meters so that is 40 courts in 1 kilometer.
