Answer:

6.25 feet.

Step-by-step explanation:

Please find the attachment.

Let L be the length of the ramp in feet.

We have been given that steel loading ramps are used to load a lawn mower onto a truck bed 37.5 inches above the ground. The ramp make a 30° angle with the ground.

We can see from our attachment that ramp and truck bed forms a right triangle with ground. The truck bed is opposite side and length of ramp is hypotenuse of our given angle.

Since we know that Sine relates the opposite and hypotenuse of a right triangle, so we will use Sine to solve for L.

$\text{Sine}=\frac{\text{Opposite}}{\text{Hypotenuse}}$

Upon substituting our given values in above formula we will get,

$\text{Sin(30)}=\frac{37.5}{L}$

$L=\frac{37.5}{\text{Sin(30)}}$

$L=\frac{37.5}{0.5}$

$L=75$

Therefore, the length of the ramp is 75 inches.

Let us convert the length of ramp in feet.

1 feet = 12 inches.

$\text{75 inches}=\frac{75\text{ inches}}{\frac{12\text{ inches}}{\text{feet}}}$

$\text{75 inches}=\frac{75\text{ inches}}{12}\times \frac{\text{ feet}}{\text{inches}}$

$\text{75 inches}=\frac{75}{12}\times\text{ feet}$

$\text{75 inches}=6.25\text{ feet}$

Therefore, the length of the ramp is 6.25 feet.

They are congruent. I believe it is ASA because both triangles have two angles identical to the other triangle with shows it had equal angles so using process of elimination I’m assuming it’s ASA because it includes two angles lol

Jacey obtains a 30-year 6/2 ARM at 4% with a 2/6 cap structure in the amount of $224,500. What is the monthly payment during the

Juli2301 [7.4K]

General Idea:

We need to make use of the below formula to find the monthly payment..

$Monthly \; Payment\; =\; \frac{P \times \frac{r}{12}}{(1-(1+\frac{r}{12})^{-m})} \\ \\ Where:\\ P\; is\; Principal\\ r\; is\; rate\; in\; decimal\; form\\ m\; is\; number\; of\; monthly\; payments$

Applying the concept:

Given:

$P=\$224,500\\ r=4\%=0.04\\ m=30\; year \times 12 \; months/year=360\\$

Substituting the given in the formula we will get the monthly payment.

$Monthly\; Payment\; =\; \frac{224500 \times \frac{0.04}{12}}{(1-(1+\frac{0.04}{12})^{-360})} =\frac{\frac{8980}{12}}{(1-0.301796)} =\frac{748.3333}{0.698204} \\ \\ Monthly \; Payment= \$1071.7975$

Conclusion:

The monthly payment during the initial period is <u>$1072</u>.
