Answer:

7,491,001 --> 7,500,000

Step-by-step explanation:

This is because rounding happens like this:

The rounding rule is: 5 and above rounds up, and 4 and under rounds down.

Here is a little rhyme for the rule: <em>5 and above rounds up like a dove. 4 and below, get down low!</em>

7,<u>4</u>91,001 --> you want to round the underlined digit. You round using the next digit to the right. The next digit over is the 9. Remember our rounding rule. Since 9 is above 5, the 4 would round up. Note - the digits after the rounded number always become zeros, even if you round up or down. So our new number is 7,500,000.

I hope I helped!

A bonsai tree is 18 inches wide and stands 2 feet tall. What is the ratio of the width of the bonsai to its height?

Afina-wow [57]

Answer:

3:4

Step-by-step explanation:

Before we start to deal with the ratio, we need all lengths in the same units.

The width is 18 inches.

The height is 2 feet.

Let's convert the height to inches. Then we will have both dimensions in the same units, inches.

2 ft * (12 in.)/ft = 24 in.

Now we have:

width = 18 in.

height = 24 in.

ratio of width to height = 18 in. to 24 in. = 18/24 = 3/4 = 3:4

Answer:

6.2 million

Step-by-step explanation:

The number of women who voted was ...

0.49 × 104.9 million = 51.401 million

The number of men who voted was ...

0.47 × 96.2 million = 45.214 million

The difference is ...

(51.401 -45.214) million = 6.187 million

About 6.2 million more women voted than men.

How much would $14,250 be worth in a savings account after 13 years if the account has a 5.25% APY and the interest is compounde

miss Akunina [59]

Answer:

$28,188.46

Step-by-step explanation:

The formula you need is:

$A(t)=P(1+\frac{r}{n})^{nt}$

Where A(t) is the amount after the compounding, P is the initial investment, r is the interest rate, n is the number of compoundings per year, and t is the time in years. We are looking for A(t). P is $14,250; r in decimal form is .0525; n is 52 since there are 52 weeks in a year; t is 13 years. Filling in:

$A(t)=14,250(1+\frac{.0525}{52})^{(52)(13)}$

Simplifying inside the parenthesis and the exponential multiplication:

$A(t)=14,250(1.0010096154)^{676}$

Raising the number in parenthesis to the power of 676 gives us:

A(t) = 14,250(1.978137432)

Multiplying then gives us $28,188.46

Un cable guía de 600 pies esta sujeto a la parte superior de una torre de comunicaciones. Si el cable forma un ángulo de 65° con

natita [175]

Answer:

La torre tiene 543.78 pies de altura.

Step-by-step explanation:

Podemos pensar en esta situación como si fuera un triángulo rectángulo, donde el cable es la hipotenusa y la torre es uno de los catetos. (Abajo se puede ver un dibujo de esta situación).

Nosotros queremos encontrar el valor de H, que es el cateto opuesto al ángulo conocido de 65°.

Entonces simplemente podemos usar la relación:

Sin(θ) = (cateto opuesto)/(hipotenusa)

donde:

cateto opuesto = H

θ = 65°

hipotenusa = 600 ft

sin(65°) = H/600ft

sin(65°)*600ft = H = 543.78 ft

La torre tiene 543.78 pies de altura.
