Terry sees this offer refurbished phone 35% off now only ?78 what was the original price

Ronch [10]

Answer:

$223.

Step-by-step explanation:

Let x be the original price of phone.

We are told that Terry sees this offer refurbished phone 35% off now only $78.

We need to find x such that 35% of x is 78. We can represent this information as:

$\frac{35}{100} x=78$

$0.35 x=78$

$x=\frac{78}{0.35}$

$x=222.8571428571428571\approx 223$

Therefore, the original price of phone was $223.

Trigonometry

Mashcka [7]

The area of the triangle EFG is 7.4 square units.

Explanation:

Given that the measurements of the sides of the triangle are EF = 8, EG = 8 and $m\angle E=22^{\circ}$

We need to determine the area of the triangle EFG

<u>Area of the triangle:</u>

The area of the triangle EFG can be determined using the formula,

$\text {Area}=\frac{1}{2} fg \sin E$

Substituting the values, we get,

$\text {Area}=\frac{1}{2} (5)(8) \sin 22^{\circ}$

Simplifying the values, we have,

$\text {Area}=\frac{1}{2}(40)(0.37)$

Multiplying, we get,

$\text {Area}=\frac{14.8}{2}$

Dividing, we get,

$\text {Area}=7.4$

Hence, the area of the triangle EFG is 7.4 square units.

100% pure gold is 24 karat gold, which is too soft to be made into jewelry most call Jory is 14 karat gold proximally 58% gold 1

denis-greek [22]

Answer:

The amount of gold used in a 200 g 14 gold bracelet is 116 g.

Step-by-step explanation:

Since a 14 karat jewell is stated to have aproximally 58 % of it's weigh in gold we need to take the total weigh of the jewel in question and find that percentage of it's weigh. In order to find that percentage we'll first convert that number into a decimal, we do that by dividing it by 100, so we have 58% = 58/100 = 0.58 we can multiply this value by the weigh of the jewel to find the amount of gold used. So we have:

gold used = total weigh*0.58 = 200*0.58 = 116 g
