Answer:
D. b > 3 2/15
Step-by-step explanation:
If a= 11, solve for b and c (will give Brainliest ❤️)
Answer:
a = 11
b = 11
c = 11√2
It is an equilateral triangle, because to angles are equal (45°).
[tex] |a| = |b| = 11 \\ |c^{2} | = \sqrt{ {a}^{2} + {b}^{2} } \\ c = \sqrt{ {11}^{2} + {11}^{2} } \\ c = 11 \sqrt{2} [/tex]

Answer:
a) 198.7% interest
Not too sure about answer to (b)
b) 4.75% annualized
Step-by-step explanation:
a) i used Interest = Principal x Rate x Time
40 = 525 x [tex]\frac{14}{365}[/tex] x r
40 = 20.13r
r = 1.987 or 198.7%
b) i used this proportion: [tex]\frac{1.98}{1/24}[/tex] = [tex]\frac{x}{1}[/tex] 'x' represents annualized rate
1/24 represents 2 weeks out of a year
1/24x = 1.98
x = 4.75%

Answer:
1. 75% of 10 liters of milk = 0.75 * 10 liters of milk = 7.5 liters of milk
2. To find 75% of a number, multiply the number by 0.75.
Answer by mathstudent55 give credit to him/her
Answer 7.5
Step-by-step explanation:
You can find this by dividing the number by 10, for example let’s use the number 20.
you would divide 20 by 10 which is 2 and times it by 7.
This is 14.
By finding this you have found 70% of 20.
now to find 5%, i would divide 20 by 10 once again which is 2 and then i would divide it by 2 which is 1.
then you would add the 2 numbers so 14+1 to get 15 therefore 75%of 20=15

Alexis can buy an 12-pound- bag of dog food for $10.80 or an 8-pound bag of the same dog food for $10.20. Which is the better buy?
Answer:
The 12-pound bag of dog food.
Step-by-step explanation:
To find out which is the better buy you start by divinging 10.80 by 12 and then you divide 10.20 by 8 and you get .90 cents for the 12 pound while you get 1.275 dollars. Which means the 12 pound bag is the better by because it is less money per pound than the 8 pound bag.

Berry Delicious is a popular shop that sells chocolate-covered strawberries. Last year, the shop used 9,200 kilograms of strawberries to make its treats. This year, the shop used 7,739.4 kilograms. What is the percent of decrease in the amount of strawberries used annually?
Answer:
15.9%
Step-by-step explanation:
Percent decrease formula =
(Initial value - New value/Initial value) × 100
Initial value = 9200kg
New value = 7739.4kg
Percent decrease = (9200 - 7739.4/9200) × 100
Percent decrease = (1460.6/9200) × 100
Percent decrease = 15.8760869565%
Approximately = 15.9%
The percent of decrease in the amount of strawberries used annually is 15.9%

Solve the system of equations using the substitution method. Make sure to check your solution.
y = 3x + 2
-4x + 4y = 16
In the blanks below, type just the number for the x-coordinate in blank 1 and just the number for the y-coordinate in blank 2.
x-coordinate:
y-coordinate:
Answer: X = 1
Y= 5
Step-by-step explanation:
Plug in y = 3x + 2 in the Y coordinate to find X
-4x + 4(3x + 2) = 16
Now you can solve for X
X = 1
Then plug in 1 in the X coordinate to find Y
-4(1)+ 4y= 16
Now you can solve for Y
Y= 5

Question 6
Which is the graph of y= 2x-3?
Answer:
Graph A
Step-by-step explanation:
The line is going to pass through -3 as the y intercept then you go over 4 blocks and up 3 of x
Answer:
Graph A
Step-by-step explanation:
If you take a pair of x,y coordinates from each graph and input it into the equation (y=3/4x-3), only Graph A makes the equation true.
Work out the equation of a line which has a gradient of 1/2 and passes through the point 4,-2? Pls answer i dont know
Answer:
y-y1=m (x- x1)…………..(1)
Here m=1/2 and (x1,y1)= (4,-2)
(1) => y-4=1/2(x+2)
=> 2y-8=x+2
=> x-2y-10=0
So, equation of line is x-2y-10=0.

The perimeter of a rectangular plot of land
is 46.4m. If the width of the plot is 7.4m.
what is its length?
A. 15.8m
B. 8.8m
C. 13.6m
D. 9.2 m
Answer:
A. 15.8
Step-by-step explanation:
First the perimeter of a rectangle = 2 (L +W)
So; 46.4 = 2(L + 7.4)
46.4 = 2L + 14.8
2L = 46.4 - 14.8
2L = 31.6
L =15.8

Answer:
2 - sqrt(3)
Step-by-step explanation:
Split pi/12 into two angles where the values of the six trigonometric functions are known.
tan (pi/4 - pi/6)
Apply the difference of angles identity
[tex]\frac{tan(pi/4) - tan(pi/6)}{1 + tan(pi/4)tan(pi/6)}[/tex]
tan(pi/4) = 1 , tan(pi/6) = (sqroot3)/3
Plug in and Simplify
[tex]\frac{1-\frac{\sqrt{3} }{3} }{1+1\frac{\sqrt{3} }{3} }[/tex]
[tex]\frac{\frac{3-\sqrt{3} }{3} }{\frac{3+\sqrt{3} }{3} }[/tex]
[tex]\frac{3-\sqrt{3} }{3} *\frac{3}{3+\sqrt{3} }[/tex]
[tex]\frac{3-\sqrt{3} }{3+\sqrt{3}}[/tex] Need to multiply this by [tex]\frac{3+\sqrt{3} }{3+\sqrt{3} }[/tex]
Expand and simplify numerator: [tex]\frac{6}{(3+\sqrt{3} )^{2} }[/tex]
Expand and simplify denominator: [tex]\frac{6}{12+6\sqrt{3}}[/tex]
Cancel the common factor: [tex]\frac{1}{2+\sqrt{3}}[/tex]
Answer:
D: 1/2 - √3.
Step-by-step explanation:
The Unit Circle is a circle with radius 1 that is used to determine the value of sine and cosine of any angle.
But that table do not directly give the exact value so to solve for its exact value, express π/12 as a sum or difference of two angles where the values of the six trigonometric functions are known.
tan π/12 = tangent (π/4 - π/6)
Using the the difference of angles identity we get,
tan (π/4 - π/6) = (1 - √3 / 3) / (1 + 1 x √3 / 3)
Multiply by 3,
tan (π/4 - π/6) = (3 - √3) / (3 + √3)
Multiply by 3 - √3
tangent (π/4 - π/6) = (3 - √3)(3 - √3) / (3 - √3)(3 + √3)
FOIL and simplify.
tangent (π/4 - π/6) = 9 - 6√3 + 3 / 9 -3
tangent (π/4 - π/6) = 1/2 - √3
