Answer:

1) 1(1/32)

2) 1.8

Step-by-step explanation:

2(3/4)=11/4

2(2/3)= 8/3

(11/4)/(8/3)=33/32

33/32= 1(1/32)

1(4/5)=9/5

9/5=1.8

Answer:

cos = 0.89/1.9 = 0.46842105263157895-

Step-by-step explanation:

the value of cos(t) is approximately 0.347.

To find the value of cos(t), we can use the identity:

tan²(t) + 1 = sec²(t)

Since we know the value of tan(t) is approximately 2.7, we can calculate sec(t):

sec²(t) = tan²(t) + 1

sec²(t) = 2.7² + 1

sec²(t) = 7.29 + 1

sec²(t) = 8.29

Now, to find sec(t), we take the square root of both sides:

sec(t) = √(8.29)

sec(t) ≈ 2.877

Finally, we can find cos(t) using the reciprocal identity:

cos(t) = 1 / sec(t)

cos(t) ≈ 1 / 2.877

cos(t) ≈ 0.347

So, the value of cos(t) is approximately 0.347.

Answer:

B

Step-by-step explanation:

[tex]4x^{2}-11x-3=0\\4x^{2}-12x+x-3=0\\4x(x-3) + (x-3) = 0\\(4x+1)(x-3)=0[/tex]

B is factorable through this method

Answer:

A) Variable "x" is less than it equal to 1 because your domain can’t have [h(x)] because that’s your function and would be your range but in this case it’s your domain and your domain or else known as the variable "x" coordinate would have to be the number on the x axis that your line starts, your line begins on line 1 on the x axis which would be your domain

Answer:

-24x - 38y

Step-by-step explanation:

[tex]-4(3x+2y)+6(-2x-5y)~(Given)\\\\-12x-8y+-12x-30y~(Distributive~property)\\\\-24x-38y~(Add~like~terms)[/tex]

Answer:

Step-by-step explanation:

4(3x+2y)+6(−2x−5y)

Use the distributive property to multiply −4 by 3x+2y.

−12x−8y+6(−2x−5y)

Use the distributive property to multiply 6 by −2x−5y.

−12x−8y−12x−30y

Combine −12x and −12x to get −24x

−24x−8y−30y

Combine −8y and −30y to get −38y.

and you get −24x−38y

Answer:

Dividing Decimals

Step 1: Estimate the answer by rounding .

Step 2: If the divisor is not a whole number, then move the decimal place n places to the right to make it a whole number.

Step 3: Divide as usual.

Step 4: Put the decimal point in the quotient directly above where the decimal point now is in the dividend.

Step-by-step explanation:

Step 1. Turn the second fraction (the one you want to divide by) upside down

(this is now a reciprocal).

Step 2. Multiply the first fraction by that reciprocal

Step 3. Simplify the fraction (if needed)

Answer:

D

Step-by-step explanation:

D is the only option where Tim has 23 or more dollars earned.

To show this I will solve each equation...

A) (-23)+9+9 = (-23)+18= -5

-5 < 0 so A doesn't work

B) (-23)+7+7+7 = (-23)+21= -2

-2 < 0 so B doesn't work

C) (-23)+12+9 = (-23)+21= -2

-2 < 0 so B doesn't work

D) (-23)+12+12 = (-23)+24= 1

1 > 0 so D does work!

* I am using 0 to compare each number with the result because Tim should have 0 or more dollars after paying his mom.
