An underestimate of 532 times 11 is 5852
prisoha [69]3 years ago
6 0

Answer:

5320 could be an underestimate 532 times 11.  

Step-by-step explanation:

We are given the following information in the question:

We have to write an underestimate of 532 times 11.

It is clear that the underestimate will be less than  532 times 11.

Thus,

532\times 10 = 5320

This could clearly be an underestimate.

To calculate the exact value:

532\times 11\\=532\times(1)+1)\\=532\times 10 + 532\times 1\\=5320 + 532\\=5852

Identify BR rounded to the nearest tenth. HELP PLEASE!!
ahrayia [7]

Answer:

<h2>BR ≈ 49.0</h2>

Step-by-step explanation:

Use cosine:

cosine=\dfrac{adjacent}{hypotenuse}

We have

adjacent=42\\hypotenuse=BR\\\alpha=31^o

\cos31^o\approx0.8572

Substitute:

\dfrac{42}{BR}=0.8572

\dfrac{42}{BR}=\dfrac{8,572}{10,000}          <em>cross multiply</em>

8,572BR=420,000                <em>divide both sides by 8,572</em>

BR=\dfrac{420,000}{8,572}

BR\approx49.0

Yvonne put $4,00 in a savings account. At the end of three years, the account had earned $960 in simple interest.
julsineya [31]
Important variables to know:

I = interest
P = principal (investment)
R = simple interest rate
T = years

Formula: I = PRT

What information do we have?
I = $960
P = $4000
T = 3 years
R = ?

Plug into formula:

960 = 4000(3)(R)
960 = 12000R
R = 960/12000
R = .08

A. $4000 + $960 = $4960. (A= P+ I)
B. 8% (.08)

Part 2: 1080 = 4000*.09*3
A = 5080 - 4960 =$420.
