Answer:
i guess by 100%
Step-by-step explanation:
increased in weight= 10
percentage increase=( increased weight by initial weight)×100
= (10/10)*100
100%
Answer:
The sales price of the skirt was $14.3.
Step-by-step explanation:
From the information given, you know that the total for the three items is $32.35 which is:
x+y+z=32.35
x is a skirt
y is a pair of shoes
z is a pair of socks
Also, you know that the pair of socks costs $3.75, so you can replace the value of z and subtract this from the total amount to have the price of the skirt plus the pair of shoes:
x+y+3.75=32.35
x+y=32.35-3.75
x+y=28.6
Now, as the original prices of the skirt and shoes were the same and you know that the sum of the two items is equal to $28.6, you can divide this by 2:
$28.6/2=$14.3
According to this, the answer is that the sales price of the skirt was $14.3.
Answer:
No.
Step-by-step explanation:
An equilateral triangle is made when all three sides of the triangle are congruent, which means that the angles will also be congruent. A right triangle is defined by its 90° angle. The total angle measures of a triangle add up to 180°. This means that the other two angles have to add up 90° because one measure is already half of 180. Since the measures have to add up to 90, they won't each be equal to 90. This means that the triangle won't be equilateral. (or, you can't have three 90° angles in a triangle because that would pass the 180° measure)
Also, the use of the Pythagorean theorem shows that the sum of the legs squared is equal to the hypotenuse. Thus, the hypotenuse in a right triangle will always be the longest side, which means that it can't be an equilateral triangle.
Answer:
when x= -4, y= 2
when x= 6, y =7
Step-by-step explanation:
We have the x values, so we can plug them in and solve. for the first problem, it becomes y =1/4 (-4)^2 -2
first we do the exponent
y= 1/4 (16) - 2
Then the multiplication
y= 4-2
then subtraction
y=2
For the second problem, it becomes y= 1/4 (6)^2 -2 We follow the same steps
y = 1/4 (36) - 2
y= 9-2
y= 7
Area=1/2*base*height
given that ABC is right angled triangle, the height will be given by:
tan theta=opposite/adjacent
tan 60=h/6
h=6tan60
=10.4
thus the area will be:
A=1/2x6x10.4
=31.2 cm^2
