Answer:

lower=34.15 upper=34.25

Step-by-step explanation:

Because sine and cosine are complements, we will have that:

cos(60°) = 1/2.

First, because cosine and sine are complements, we know that:

cos(x) = sin(x + 90°).

cos(90° - x) = sin(x).

We will use the second relation, with x = 30° we can write:

cos(90° - 30°) = sin(30°)

cos(60°) = sin(30°)

And we know that sin(30°) = 1/2

Then we also have cos(60°) = 1/2.

So the correct option is d.

Answer:

Step-by-step explanation:

<Q is common to both triangles.

130 / 40 = 3.25

Call DQ = x

40/130 = x / (x + 72)       Cross multiply

40*(x + 72) = 130*x

40x + 2880 = 130x      Subtract 40 x from both sides

2880 = 90 x                 Divide by 90

x = 32

(72 + 32)/32 = 104/32 = 3,25

The ratios are the same.

Therefore the triangles are similar by SAS

Answer:

0.318= 0.32 hope this helps tell me if I'm wrong

Edit: 0.318. 1 is in the hundredths place so 8 would bump it up to 2 so it would be 0.32

The given fraction in decimal form as 0.32.

The given fraction is 7/22.

The fraction bar separating the “part” and the “whole” represents division. This means that all fractions can be converted into decimals by dividing the numerator by the denominator.

Now, the given fraction can be converted to decimal as follows

7/22 = 0.3181

To the nearest hundredths is 0.3181 ≈ 0.32

Therefore, the given fraction in decimal form as 0.32.

Answer:

Braxton's initial investment is equals to (=) Pam's initial investment.

The interest on Braxton's account is less than (< ) the interest on Pam's account.

Step-by-step explanation:

Given - Braxton has money in a savings account. The equation

            B = [tex]800(1 + 0.03)^{t}[/tex] can be used to calculate the amount of money    

           in dollars, B, Braxton has in his account after t years since opening

           the account.

           Pam also has money in a savings account. The equation

           P=[tex]800(1 + 0.04)^{t}[/tex]  can be used to calculate the  amount of money in

           dollars, P, Pam has in her account after t years since opening the

           account.

To find - Braxton's initial investment ..........Pam's initial investment.

             The interest on Braxton's account .....the interest on Pam's account.

Proof -

As given, Broxton equation is - [tex]800(1 + 0.03)^{t}[/tex]

               Pam equation is - [tex]800(1 + 0.04)^{t}[/tex]  

Now,

1.)

For initial investment , Put t = 0

⇒B = [tex]800(1 + 0.03)^{0} = 800(1) = 800[/tex]

  P =  [tex]800(1 + 0.04)^{0} = 800(1) = 800[/tex]

As for t = 0

Braxton's equation , B = Pam's equation,P

⇒Braxton's Initial investment = Pam's initial investment.

2.)

For the interest,

As we don not have time for which the interest has to be check.

So , let the time period = 5 years

Therefore,

B = [tex]800(1 + 0.03)^{5} = 800(1.03)^{5} = 800(1.1593) = 927.42[/tex]

P =  [tex]800(1 + 0.04)^{5} = 800(1.04)^{5} = 800(1.2166) = 973.32[/tex]

Now,

Interest on Braxton's account = 927.42 - 800 = 127.42 ≈ 127

Interest on Pam's account = 973.32 - 800 = 173.32 ≈ 173

∴ we get

The interest on Braxton's account is less than the interest on Pam's account.

Answer:

x = 11

Step-by-step explanation:

35 + 5x = 90    {Complementary angles}

Subtract 35 from both sides

   5x = 90 - 35

  5x = 55            {Divide both sides by 5}

    x = 55/5

    x = 11

Step-by-step explanation:

Noticed how it forms a supplementary angle.

A supplmentary angle is basically two angles that added up to 180 degrees.

So we have:

64 + x = 180

Then we solve for "x", so "x" = 116.

V = 22/7 × 25 ×10

V = 22/7 × 250

V = 22 × 250 ÷ 7

Answer: The slope is 2.

Step-by-step explanation:

To get the slope, use this tip: Rise over run

Count how much it rises, which is 4, and how much it "runs' which is 2. Now put rise above run which is 4/2. This simplifies to simply 2.

Answer:

The slope is 2.

Step-by-step explanation:

The points on the line are (1, -2) which can be labeled as x1 and y1, and the other is (3,2) which can be labeled as x2 and y2. you set up the equation in the slope formula, so 2 - - 2 / 3 - 1. Since there are two negatives, the subtraction signs turn into addition signs, and you get 4/2, which simplyfied is 2. Hope this helps :)
