Answer:

x=-2.5

Step-by-step explanation:

Move the 13 to the other side making it a negative. 4.8x=1-13. simplify 4.8x=-12. 12 divided by 4.8 is 2.5.

Answer:

The value of x = 4.4 units.

Step-by-step explanation:

Given that figure A is a scale image of Figure B.

It is clear that the two sides are similar, so their corresponding angles will be congruent and corresponding sides are in proportion.

Thus, using the corresponding ratios of figure A and Figure B

$\frac{x}{4}\:=\:\frac{11}{10}$

Multiply both sides by 10

$\frac{x}{4}\cdot \:10=\frac{11}{10}\cdot \:10$

$\frac{5x}{2}=11$

$5x=22$

Divide both sides by 5

$\frac{5x}{5}=\frac{22}{5}$

$x=\frac{22}{5}$

$x = 4.4$

Therefore, the value of x = 4.4 units.

scoray [572]

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.

scZoUnD [109]

Answer:

5√5

Step-by-step explanation:

You can rewrite √75 as √(25 * 5) and since 25 is a perfect square, you can find the square root and take that outside of the square root. √25 = 5, so √75 is equal to 5√5, and that cannot be simplified furthermore.
