IrinaVladis [17]

Hey!

---------------------------------------------------

Steps To Solve:

~Find common denominators

4 2/7 = 4 10/35

2 1/5 = 2 7/35

~Turn into improper fractions

4 10/35 = 150/35

2 7/35 = 77/35

~Multiply

150/35 x 77/35 = 11,550/1,225

~Simplify

11,550/1,225 = 9 525/1,225 = 9 105/245 = 9 21/49 = 9 3/7

Y=-1,X+2y=-6 solve by substitution show all work

aev [14]

Answer:

$x=-4$

Step-by-step explanation:

$x+2y=-6$

$y=-1$

_________

$x+2\left(-1\right)=-6$

$x-2\times \:1=-6$

Multiply: 2*1= 2

$x-2=-6$

Add 2 to both sides:

$x-2+2=-6+2$

$x=-4$

Which expression is equivalent to 3^4 ⋅ 3^−9? 1/3^13 1/3^5 3^5 3^13

boyakko [2]

${3}^{4} \times {3}^{ - 9} = {3}^{4} \times (1/ {3}^{9}) = {3}^{4} \div {3}^{9} \\ {3}^{(4 - 9)} = {3}^{ - 5} = 1/( {3}^{5} )$
So the 2nd answer is correct: 1 / 3^5

A string running from the ground to the top of a fence has an angle of elevation of 45°. The string is 10 feet long. What is the

Elza [17]

Answer: The distance between the fence and where the string is pegged to the ground is 7.07 feet.

Step-by-step explanation:

Since we have given that

Length of string = 10 feet

Angle of elevation = 45°

We need to find the distance between the fence and where the string is pegged to the ground.

We will apply "Cosine formula "

$\cos 45^\circ=\dfrac{Base}{Hypotenuse}\\\\\dfrac{1}{\sqrt{2}}=\dfrac{Base}{10}\\\\Base=\dfrac{10}{\sqrt{2}}\\\\Base=7.07\ feet$

Hence, the distance between the fence and where the string is pegged to the ground is 7.07 feet.
