Answer:
2 : 1
Step-by-step explanation:
purple : red = (2/3) : (1/3) = 2 : 1
The ratio of purple paint to red paint is 2 : 1.
Answer:
Solution :-⅓ are red
So,
No. of red colors = 1/3 × 87 = 29
No. of purple colors = 2/3 × 87 = 2 × 29 = 58
So,
Ratio = 58:29
Ratio = 2:1

pls help i need to know what x/-4 + 6 < 11 is?!?!!?!?!
Answer:
x ∈ ( - ∞ , 20 )
Step-by-step explanation:
Given :
x / 4 + 6 < 11
Adding - 11 both we get:
= > x / 4 + 6 - 11 < 11 - 11
= > x / 4 - 5 < 0
Multiply by 4 both we get:
= > x - 20 < 0
Adding 20 both side we get:
= > x - 20 + 20 < 20
= > x < 20
Solution set x ∈ ( - ∞ , 20 )
Hence we get required answer!

Answer:
x > -20
Step-by-step explanation:
This is a "2-step" inequality with a negative coefficient.
x/-4 +6 < 11 . . . . . given
x/-4 < 5 . . . . . . . . subtract 6 from both sides
x > -20 . . . . . . . . .multiply both sides by -4
Because the multiplier is negative, the sense of the comparison must be reversed.
_____
Check
x = -24 should not be in the solution set: -24/-4 +6 < 11 ⇒ 12 < 11 . . . False
x = -16 should be in the solution set: -16/-4 +6 < 11 ⇒ 10 < 11 . . . True

14.4 = -2.4b
Answer:
b = -6
Step-by-step explanation:
14.4 = -2.4b (swap the sides of the equation)
-2.4b = 14.4 (divide both sides of the equation by -2.4)
b = -6
Is a triangle with side lengths of 10, 11, 14 a right triangle?
Answer:
no
Step-by-step explanation:
A right triangle has a formula a^2+b^2=c^2 with c being the longest side (hyponotuse). 10 squared is 100, 11 squared is 121, so add those and get 221. 14 squared is only 196 which is not equal to 221 so it is not a right triangle

Yes

will give brainliest m^2= -7m + 6
Answer:
m =(-7-√73)/2=-7.772
Step-by-step explanation:
Answer:
m=−7/2+1/2√73 or m=−7/2+−1/2√73
Step-by-step explanation:
Let's solve your equation step-by-step.
m2=−7m+6
Step 1: Subtract -7m+6 from both sides.
m2−(−7m+6)=−7m+6−(−7m+6)
m2+7m−6=0
For this equation: a=1, b=7, c=-6
1m2+7m+−6=0
Step 2: Use quadratic formula with a=1, b=7, c=-6.
m=−b±√b2−4ac/2a
m=−(7)±√(7)2−4(1)(−6)/2(1)
m=−7±√73/2
m=−7/2+1/2√73 or m=−7/2+−1/2√73

Find the circumference and area of the circle. Use 3.14 for π. Round to the nearest hundredth if necessary.
13m.
Answer:
81.64
Step-by-step explanation:
Answer:
Step-by-step explanation:
Please be explicit in labeling the radius. I will assume y ou meant r = 13 m.
Circumference formula: C = 2πr; area formula: A = πr²
Here, with r = 13 m, C = 2π(13 m) = 26π m = C = 81.68 m
and
with r = 13 m, A = π(13 m)^2 = 169π = A = 530.93 m^2

Evaluate the polynomial function when H=3
f(h)=4h^3-3h^2+5h-16
Answer:
80
Step-by-step explanation:
f(3)=4(3)^3-3(3)^2+5(3)-16
f(3)=4(3*3*3)-3(3*3)+15-16
f(3)=4(27)-3(9)+15-16
f(3)=108-27+15-16
f(3)=81+15-16

If you were to use the “Completing the Square” method to solve the equation below for k, what number would you add to both sides of the equation? k 2- 8k = -4
A) 16
B) –16
C) 24
D) –24
Answer:
The number you would add to both sides of the equation to use the "Completing the Square" method would be 16.
Step-by-step explanation:
To find the number to add to both sides of an equation to complete the square, divide the first-degree term's coefficient by 2 and square your remainder. In this case, the coefficient of the first-degree term is -8. After dividing by 2 and squaring it, you'll get 16, so that is the number you must add to both sides of the equation in order to complete the square.

A car wheel has a diameter of 27.1". How far will the car go when the wheels rotate 100 times?
Answer:
135.5"
Step-by-step explanation:
Answer:
8509.4
Step-by-step explanation:
The diameter has already been displayed so what I could simply do is solve the equation simply by using the formula for circumference using diameter (C=3.14 x 27.1) and that will get me 85.094 but thats how far it will get if it rotates 1 times so we must multiply it by 100 and move the decimal point 2 digits to the right and the final answer is 8509.4. 8509.4 (no mathematical unit) is how far the car can go when the wheels have a diameter of 27.1 and rotates 100 times.1.)

Pryia and 3 friends go out to dinner and split the cost equally. The meal costs $98, tax is 9% and they leave a 20% tip based the cost of the meal. How much money does Pryia need?
Answer:
$42.14
Step-by-step explanation:
Given data
Cost of meal= $98
tax= 9%
Tip= 20%
Let us find the amount of the tax and the tip
Tax
=9/100*98
=0.09*98
=$8.82
Tip
=20/100*98
=0.2*98
=$19.6
Hence the total amount paid is
=98+8.82+19.6
=126.42
The amount paid by Pryia
=126.42/3
=$42.14
