Answer:
Equation : [tex]\frac{2}{5}r=8[/tex]
She can make 20 bows with 8 yards of ribbon
Step-by-step explanation:
Gloria needs 2/5 yard of ribbons to make each bow.
Length of 1 bow =[tex]\frac{2}{5} yards[/tex]
Let r be the no. of bows made
So, Length of r bows = [tex]\frac{2}{5}r[/tex]
We are given that she can make r bows with 8 yards of ribbon
So, Equation : [tex]\frac{2}{5}r=8[/tex]
[tex]r=\frac{8 \times 5}{2}[/tex]
r=20
Hence She can make 20 bows with 8 yards of ribbon

Question:
Kira is using the figure shown to prove the Pythagorean theorem. She starts by writing the
equation [tex](a+b)^2 - c^2 = 4(\frac{1}{2}ab )[/tex] because she knows two equal ways to represent the area
of the shaded region. Which best describes the next steps Kira should take to complete her
proof?
Answer:
The correct option is;
d. Simplify both sides of the equation to get a² + 2·a·b + b² - c² = 2·a·b then subtract 2·a·b and add c² to both sides of the equation
Step-by-step explanation:
Here we have
The area of the larger square = (a + b)²
The area of the middle plain shaded square = c²
∴ Area of the shaded region = (a + b)² - c²
The shaded region consists of for right triangles of base, a and height, b therefore, the area of the shaded region is also the area of the four right triangles = 4 × (1/2 × base × height)
= 4×1/2×a×b = 4(1/2·a·b)
Hence area of the shaded region also = 4(1/2·a·b)
Therefore, (a + b)² - c² = 4(1/2·a·b)
Which is a² + 2·a·b + b² - c² = 4 × 1/2 × a·b = 2·a·b
∴ a² + 2·a·b + b² - c² = 2·a·b
Hence a² + 2·a·b + b² - c² + c² = 2·a·b + c² gives
a² + 2·a·b + b² = 2·a·b + c² gives
Also a² + 2·a·b + b² - 2·a·b = 2·a·b + c² - 2·a·b gives
a² + b² = c² which is Pythagoras theorem

3(K-2)=15
How do I solve for K
Answer:
7
Step-by-step explanation:
step 1. divide 15 by 3
(K-2)=5
step 2. add the 2 to the 5
K=7
Answer: k = 7
Step-by-step explanation: Start by distributing the 3 through the parentheses on the left side of the equation.
3(k) is 3k and 3(-2) is -6.
So we have 3k - 6 = 15.
Next, isolate the k term by adding 6 to both
sides of the equation and we get 3k = 21.
Now divide both sides by 3 and k = 7.
If you want, you can check your answer by plugging a 7
back into the original equation to see if it works.

What is t in degrees?
Answer:
100
Step-by-step explanation:
Because the 40 degree angle is an inscribed angle opposite of arc u, arc u's angle measure must be 40*2=80 degrees. Since t+u=180 degrees, t must be 100 degrees. Hope this helps!

In ΔIJK, the measure of ∠K=90°, JK = 90 feet, and KI = 54 feet. Find the measure of ∠I to the nearest tenth of a degree.
9514 1404 393
Answer:
∠I = 59.0°
Step-by-step explanation:
The applicable trig relation is ...
Tan = Opposite/Adjacent
tan(I) = JK/KI = 90/54
I = arctan(90/54) ≈ 59.04°
The measure of angle I is about 59.0°.

How do u find the unknown angle measure in a triangle
Answer:
Use the sum of angle measures rule.
Step-by-step explanation:
If you are given two angles and one missing angle, it's good to remember that all angles add up to 180°.
You can add the the given angles measurements, and subtract them by 180. You should then get the missing angle measure.

When you add fractions is the sum always greater than 1?
Answer:
Not always
Step-by-step explanation:
Some fractions, like 1/2, if you add it with 1/2, it equals one.
Halves will always equal one, and they are fractions too, so technically not all addition of fractions are greater than 1.

-9x+3y=-30 in slope intercept form
Answer:
y = 3x - 10
Step-by-step explanation:
Answer:
y = 3x -10
Step-by-step explanation:
Slope intercept form is y = mx+b where m is the slope and b is the y intercept
-9x +3y =-30
Add 9x from each side
-9x+9x +3y =9x-30
3y = 9x-30
Divide each side by 3
3y/3 = 9x/3 -30/3
y = 3x -10
The price of a cup of coffee was $2.35 yesterday. Today, the price fell to $2.10. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answer:
10.6% decrease
Step-by-step explanation:
The percentage change in a quantity is computed using ...
percentage change = ((new value)/(old value) -1) × 100%
= (2.10/2.35 -1) × 100%
= (0.8936 -1) × 100%
= -.1064 × 100%
= -10.64%
The percentage decrease was about 10.6%.
Complete the point-slope equation of the line through (-9,6)(−9,6)left parenthesis, minus, 9, comma, 6, right parenthesis and (-7,-8)(−7,−8)?
Answer:
Step-by-step explanation:
hello : here is an solution
The equation of the line in point-slope form is y - 6 = -7(x+9)
The equation of a line in point-slope form is expressed as:
y-y0 = m(x-x0)
m is the slope of the line
(x0, y0) is any point on the line
Given the coordinate points (-9, 6) and (-7, -8)
Get the slope of the line:
slope = -8-6/-7+9
Slope = -14/2
Slope = -7
Using the point (-9, 6), the required slope is expressed as:
y - 6 = -7(x-(-9))
y - 6 = -7(x+9)
Hence the equation of the line in point-slope form is y - 6 = -7(x+9)

Step 2: Radii OK and NL are perpendicular to OM because of the radius-tangent theorem. By definition of perpendicular, angles KOM and LNM are right angles. This means that triangles KOM and LNM are right triangles. Angle LMN is common to both right triangles, so by the _________________________, triangles KOM and LNM are similar. please fill in the blank
Answer:
AAA postulate.Step-by-step explanation:
Givens
Angles KOM and LNM are congruent, because both are right.Angle LNM is common to both triangles.If two internal angles of two triangles are congruent, then the third angle is also congruent.
Therefore, the similarity is proven by AAA postulate, which states that if we have three corresponding angles congruent, then those triangles are similar.
Remember that similarity is about proportion between sides and congruence between angles.
