Answer:

2.4 miles

Step-by-step explanation:

This is a simple ratio problem.

Penguins go 4/5 mile in 1/3rd hour. <em>So how many miles will they go in 1 hour? Let that be x:</em>

<em> $\frac{\frac{4}{5}}{\frac{1}{3}}=\frac{x}{1}\\\frac{1}{3}x=\frac{4}{5}\\x=\frac{4}{5}*3=\frac{12}{5}$ </em>

<em />

<em>That is 12/5 miles or 2 2/5 miles</em>

<em>In decimal, that's </em><em>2.4 miles</em>

A rectangle is inscribed in a right isosceles triangle, such that two of its vertices lie on the hypotenuse, and two other on th

Rufina [12.5K]

Answer:

Part 1) The base is $25\ in$ and the height is $10\ in$

Part 2) The base is $7.5\ in$ and the height is $18.75\ in$

Step-by-step explanation:

case 1) Right isosceles triangle of the left

Let

x------> the base of the rectangle

y----> the height of the rectangle

Remember that

In a right isosceles triangle the lengths of the legs of the triangle is the same

$y+x+y=45$

$2y+x=45$ ----> equation A

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

$x=2.5y$ -----> equation B

substitute equation B in the equation A

$2y+2.5y=45$

$4.5y=45$

$y=10\ in$

Find the value of x

$x=2.5(10)=25\ in$

case 2) Right isosceles triangle of the right

Let

x------> the base of the rectangle

y----> the height of the rectangle

Remember that

In a right isosceles triangle the lengths of the legs of the triangle is the same

$y+x+y=45$

$2y+x=45$ ----> equation A

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

$y=2.5x$ -----> equation B

substitute equation B in the equation A

$2(2.5x)+x=45$

$6x=45$

$x=7.5\ in$

Find the value of y

$y=2.5(7.5)=18.75\ in$

I need to find x can someone please help

PIT_PIT [208]

Answer:

$\boxed{\boxed{\tt x=87^{\circ}}}$

Step-by-step explanation:

We know that a triangle has 3 sides, A triangle's interior angles add up to 180 degrees.

Now, let's write this as an equation:

$\tt x^{\circ}+37^{\circ}+56^{\circ}=180^{\circ}$

The missing angle is 180° minus the sum of the other two angles.

$\tt x^{\circ}=180^{\circ}-56^{\circ}-37^{\circ}$

Subtract the numbers:

$\tt 180^{\circ}-56^{\circ}-37^{\circ}=87^{\circ}$

$\tt x=87^{\circ}$

Slove this inequality 3b-7 less the 20

Mars2501 [29]

Hi friend

#24

y/9+5=0

Simplify to both sides

1/9 y+5=0

Now subtract 5 from both sides

1/9 y+5-5=0-5

1/9 y=-5

Multiply both sides by 9 so we can find the y value

9(1/9 y)= (9)(-5)

y=-45

The answer is A ( Your answer was not good)

#25

3b-7<32

First you need to add 7 to both sides

3b-7+7=32+7

3b<39

Now divide both sides by 3 so we can find the value for b

3b/3<39/3

b<13

The answer is A

#26

3p-16<20

Now we gonna do the same thing

Add 16 to both sides

3p-16+16<20+16

3p<36

Now divide both sides by 3

3p/3<36/3

p<12

The answer is C

#27

3p-6>21

Just do the same thing

Add 6 to both sides

3p-6+6>21+6

3p>27

Divide both sides by 3

3p/3>27/3

p>9

The answer is B

I really hope that's help and good luck :0
