Answer:

The new price for one pound of apples is $1.44

Step-by-step explanation:

A 10% discount from $1.60 is $0.16, which can be found by multiplying $1.60 by 0.10. To figure out the new price, use the equation: $1.60 - $0.16= $1.44

X - the percent of increase

210+210x=260 \\
210x=260-210 \\
210x=50 \\
x=\frac{50}{210} \\
x \approx 0.238 \\
x \approx 23.8\%

The percent of increase is approximately 23.8%.

What’s the answer to 14
mars1129 [50]

Step-by-step explanation:

EF = 6x - 4

and it is also the combination of EG and GF.

so,

6x - 4 = EG + GF = EG + 13

6x = EG + 17

now, we have additional information. EF bisects CD. that means it cuts CD in half.

and that means both banks must be off equal size.

5x - 1 = 7x -13

12 = 2x

x = 6

so, back to the first problem

6×6 = EG + 17

36 = EG + 17

19 = EG

Natalie walked
creativ13 [48]

Answer:

7 miles / hour

Step-by-step explanation:

I'm taking this to mean she walked 3.5 miles. She did this 1/2 hour.

Givens

d (distance ) = 3.5 miles

t (time) = 1/2 hour

r (rate) = ?

Formula

r = d/t

Solution

The easiest way to do this is to change the fractions to decimals.

t = 1/2 = 0.5 hours

r = 3.5 / 0.5

r = 7 miles per hour.

Two sides and an angle are given. determine whether the given information results in one triangle, no triangle, three triangles,
Crazy boy [7]
We are given 2 sides 18.7, 16.1 and a NON-included angle.
We have to calculate the altitude of the triangle.
altitude = 18.7 * sine (35)
altitude = 18.7 * 0.57358
altitude = <span> <span> <span> 10.725946 </span> </span> </span>
In this case, side c is greater than the altitude and is less than side a so 2 two triangles will be formed.
