Answer:
=3/4
Step-by-step explanation:
3 (c+d) 2c-2d
-------------- * -------------
(c-d) 8c+8d
Factor the right had term. The numerator can factor out a 2 and the denominator can factor out an 8.
3 (c+d) 2(c-d)
-------------- * -------------
(c-d) 8(c+d)
We can cancel the (c+d) in the numerator the left and the denominator on the right. We can cancel the (c-d) in the numerator on the right and the denominator on the left
3 2
-------------- * -------------
1 8
We can divide the fraction on the right by 2 on the top and bottom.
3 1
-------------- * -------------
1 4
=3/4
Answer:
The measure of angle x is 40°
Step-by-step explanation:
we know that
The measurement of the outer angle is the semi-difference of the arcs which comprises
see the attached figure with letters to better understand the problem
so
m∠x=(1/2)[arc AB-arc AC]
<u><em>Find the measure of arc AC</em></u>
we know that
arc AB+arc BC+arc AC=360° ----> by complete circle
substitute the given values
arc AB=200°
arc BC=40°
arc AC=?
200°+40°+arc AC=360°
240°+arc AC=360°
arc AC=360°-240°=120°
<u><em>Find the measure of angle x</em></u>
m∠x=(1/2)[200°-120°]=40°
Answer:b=5
Step-by-step explanation:the formular for pythagoras theory is
C^2=a^2+b^2
13^2=12^2+b^2
169=144+b^2
Collect like terms
169-144=b^2
b^2=25
Take the the square root of both sides
b=square root of 25
b=5
Hello!
To find the volume of the water, we would need to use the density formula. The density formula is d = m/V.
In this formula, d is the density, m is the mass and V is the volume.
1. To find the volume of 100 grams of ice, we substitute the appropriate values into the formula and solve for the volume using basic algebra.
0.92g/cm³ = 100g/V (multiply both sides by V)
0.92g/cm³ · V = 100g (divide both sides by 0.92g/cm³)
V = 108.69 cm³.
The volume of 100 grams of ice is about 108.69 cm³.
2. To find the volume of the completely melted ice, we would use the same formula, but the density is now 1.00 g/mL.
1.00g/mL = 100g/V (multiply both sides by V)
1.00g/mL · V = 100g (divide both sides by 1.00g/mL)
V = 100 mL
Therefore, the volume of the melted ice is 100 mL.
<u>Final answers</u>:
- 108.69 g/cm³
- 100 mL
this will be the answer
1: x=-4 or x=-3 and the second can be shown clearly
