HELP I tried it but I don't see where this is going, and I don't even know what equation I would put to finish.. please help

Answers

find the equations that tell their height
starting+growth=current height
starting=1
growth=2 times number of months grown
so
1+2m=h

another one is 11 and grows at 1 per month
11+1m=h

when will heights be equal?
set them equal and solve for the numberof months
1+2m=11+1m
minus 1m both sides
1+m=11
minus 1
m=10

answer is 10 months

A grocery store sells 6 pounds of apples for $4. How much will 8 pounds of apples cost? Round your answer to the nearest cent.

Answers

Well waht you want to do here is first find the cost for one pound of apples, which is $0.66, so then you times it by eight to find the cost for eight pounds which is $5.33. I hope this helped you!

Without calculating, is 1 1/6 × 4/5 less than or greater than 1 1/6. Is the product less than or greater than 4/5? Explain your reasoning

Answers

1 and 1/6 is 1.16666666 (1 divided by 6) and if it is multipled by 1 it is still 1.1666666, so if it is multipled by a number less than 1 it will be less than the original number (multiply it by a half and you half it, this is multiplied by 0.8)

Which expression is equivalent to (st)(6)

Answers

Answer:

(st)(6)= s(6) * t(6)

Step-by-step explanation:

Lets discuss some basic expressions

(f+g)(x)= f(x) + g(x)

(f-g)(x)= f(x) - g(x)

(fg)(x) = (f*g)(x)= f(x) * g(x)

(f/g)(x)= f(x)/ g(x)

(fog)(x) = f(g(x))

(gof)(x)= g(f(x))

given expression is

(st)(6)

(st)(x)= s(x) * t(x) we multiply it

(st)(6)= s(6) * t(6)
S(6) x t(6) would be the expression that is equivalent to (st)(6)

In triangle JKL, m of angle J = 90, m of angle K = 30, and m of angle L = 60. Which of the following statements about triangle JKL are true? Check all that apply.A) KL= root 3 (JL)
B) KL= 2(JL)
C) JK= root 3 (JL)
D) JK= 2(JL)
E) JL= root 3/2 (KL)
F) JK= root 3/2 (KL)

Answers

Answer:

# Answer B is true ⇒ KL = 2(JL)

# Answer C is true ⇒ JK = √3(JL)

# Answer F is true ⇒ JK = √3/2(KL)

Step-by-step explanation:

* Lets explain the ratio between the sides of the triangle

- In Δ JKL

∵ The measure of angle J is 90°

∴ KL is the hypotenuse

∵ The measure of angle K is 30°

∴ JL is the opposite side to angle 30°

∵ The measure of angle L is 60°

∴ JK is the opposite side to the angle 60°

- There is a fact in the triangle which has angles 30° , 60° , 90°

# The length of the side opposite to the angle of measure 30° is

  half the length of the hypotenuse

∵ KL is the hypotenuse

∵ JL is the opposite side to the angle of measure 30°

∴ JL = 1/2 KL  OR KL = 2 JL

# The length of the side opposite to the angle of measure 60° is

  √3 the length of the opposite side to the angle 30°

∵ JK is the opposite side to the angle of measure 60°

∵ JL is the opposite side to the angle of measure 30°

∴ JK = √3 JL

# The length of the side opposite to the angle of measure 60° is also

  half √3 the length of the hypotenuse

∵ JK is the opposite side to the angle of measure 60°

∵ KL is the hypotenuse

∴ JK = √3/2 KL

- From the relation above

# Answer B is true ⇒ KL = 2(JL)

# Answer C is true ⇒ JK = √3(JL)

# Answer F is true ⇒ JK = √3/2(KL)

Explain how modeling partial products can be used to find the products of greater numbers.

Answers

It is easier to multiply. For example: 63 multiply by 7
63 x 7 = (60+3) x 7 =  60 x 7 + 3 x 7 =  420 + 21  =  441

Another example : 25 x 73
25 x 73 = (20+5) x (70+3) = 20 x 70 + 20x3 + 5x70 + 5x3

                                         = 1400 + 60 + 350 + 15           =  1875
