Answer:

363 ft.

Step-by-step explanation:

To calculate the base side which is b we use the trigonometric identity called cosine.

$cos \theta=\frac{base}{hypotenuse} \\\\cos25 = \frac{b}{400}\\\\b=400*cos 25\\b=400*0.906\\b=362.5\ ft$

Since we the answer to the nearest whole number it would be b = 363 ft.

If Tammy takes out a discounted loan for $850 at a simple interest rate of 12%, but only receives $800 into her bank account, wh

Vikki [24]

Answer : The duration of the loan is, 6 months

Step-by-step explanation :

First we have to determine the discounted money.

Discounted money = $850 - $800 = $50

Thus, interest = $50

Now we have to determine the time of loan.

Formula used :

$S.I=\frac{PRT}{100}$

where,

P = principle

R = interest rate

T = time

S.I = simple interest

Now put all the given values in the above formula, we get:

For 1 year : $\$50=\frac{(\$850)\times (12)\times T}{100}$

For 12 months : $\$50\times 12=\frac{(\$850)\times (12)\times T}{100}$

$T=5.88month\approx 6month$

Thus, the duration of the loan is, 6 months

There is a linear relationship between a car’s weight and its gas mileage. On average, a car that weighs 2400 lb gets 35 mi/gal

Semmy [17]

The required equation is
w - 2400 = (3000 - 2400)/(29 - 35) (g - 35)
w - 2400 = -100(g - 35)
w - 2400 = -100g + 3500
w + 100g = 3500 + 2400 = 5900
w + 100g = 5900

20 points!!<br> please show me how to do this for d + 4 < 7

Vilka [71]

Step-by-step explanation:

$d+4$

Solve for d, by subtracting 4 from both sides.

$d+4-4$

$d$

To graph the solution, draw a number line, make a hollow circle on 3 and draw an arrow pointing left towards negative numbers. The circle has to be hollow because the solution does not include 3.

To check your work, substitude d for any number less than 3. In this case, let's try with 2.

$d+4$

This is true. 7 is greater than 6.
