An isosceles triangle has an angle that measures 56º. Which other angles could be in that
isosceles triangle? Choose all that apply.
HELP PLEASE I NEED THIS
Answer:
The other angles can be 56°, 68°, or 62°.
Step-by-step explanation:
If the 56° angle is one of the two congruent angles, then the remaining angles are 56° and 180-2(56) = 68°
If the is 56° Is not congruent to either of the other angles, then each of the remaining two angles is (180-56)/2 = 62°.
The other angles can be 56°, 68°, or 62°.

Calculate the value of the sample variance. Round your answer to one decimal place. 9_5,9_5,2,9_5
Answer:
[tex]s^2 = 0.01[/tex]
Step-by-step explanation:
Given
Values: 9/5, 9/5, 2, 9/5
Required
Calculate the sample variance
Sample variance is calculated using:
[tex]s^2 = \frac{\sum (x_i - \overline x)^2}{n - 1}[/tex]
First, we calculate the mean
[tex]\overline x = \frac{\sum x}{n}[/tex]
[tex]\overline x = \frac{9/5 + 9/5 + 2 + 9/5}{4}[/tex]
[tex]\overline x = \frac{7.4}{4}[/tex]
[tex]\overline x = 1.85[/tex]
[tex]s^2 = \frac{\sum (x_i - \overline x)^2}{n - 1}[/tex] becomes
[tex]s^2 = \frac{(9/5 - 1.85)^2+(9/5 - 1.85)^2+(2 - 1.85)^2+(9/5 - 1.85)^2}{4 - 1}[/tex]
[tex]s^2 = \frac{(-0.05)^2+(-0.05)^2+(0.15)^2+(-0.05)^2}{4 - 1}[/tex]
[tex]s^2 = \frac{0.0025+0.0025+0.0225+0.0025}{3}[/tex]
[tex]s^2 = \frac{0.03}{3}[/tex]
[tex]s^2 = 0.01[/tex]
Hence, the variance is 0.01

Answer:
11.3
Step-by-step explanation:
Pythagorean theorem is a^2+b^2=c^2
8^2+8^2=128
the square root of 128 is 11.3137085
then you round to the nearest tenth and get 11.3
A steep mountain is inclined 74 degree to the horizontal and rises 3400 ft above the surrounding plain. A cable car is to be installed from a point 970 ft from the base to the top of the mountain. Find the shortest length of cable needed.
Answer:
3917m
Step-by-step explanation:
We are given that
[tex]\theta=74^{\circ}[/tex]
[tex]h=3400 ft[/tex]
We have to find the shortest length of cable needed.
Let Base=x
We know that
[tex]tan\theta=\frac{Perpendicular\;side}{Base}[/tex]
Using the formula
[tex]tan74^{\circ}=\frac{3400}{x}[/tex]
[tex]x=\frac{3400}{tan74}=975m[/tex]
[tex]y=x+970=975+970=1945m[/tex]
Now, the length of cable needed
=[tex]\sqrt{(3400)^2+(1945)^2}[/tex]
=3917m
Hence, the shortest length of cable needed=3917m

Quadrilateral EFGH is similar to quadrilateral IJKL. Find the measure of side JK. Round your answer to the nearest tenth.
Answer:
The answer is "31.888".
Step-by-step explanation:
If their respective angles become congruent or the side lengths get a constant relation, they realize that two quadrilaterals are similar
EFGH is similar to IJKL because of quadrilateral
[tex]\to \frac{FG}{JK} =\frac{GH}{KL}=\frac{HI}{LM}=\frac{FI}{JM}\\\\\to \frac{GH}{KL} =\frac{HI}{LM}\\\\\to \frac{7}{KL}= \frac{9}{41}\\\\\to KL=\frac{7 \times 41}{9}=31.888[/tex]

Step-by-step explanation:
In the given picture, it is shown that the triangles have two congruent sides, and one congruent angle between them. The congruent sides are shown by the lines on the sides. The congruent angle is shown by the box outlining the angle (technically a box outlining the angle demonstrates that the angle is a right angle, either way, it proves the congruency).

Last year, Bob's Market ordered 15 1 2 15 2 1 pounds of plums from a local orchard. This year, the market plans to order 1 1 4 1 4 1 times as many pounds of plums as were ordered last year. They want 2 5 5 2 of this order to be red plums. What is the total amount, in pounds, of red plums the market plans to order this year?
Answer: 7 3/4 pounds
Step-by-step explanation:
Here's the correct question:
Last year, Bob's Market ordered 15 1/2 pounds of plums from a local orchard. This year, the market plans to order 1 1/4 times as many pounds of plums as were ordered last year. They want 2/5 of this order to be red plums. What is the total amount, in pounds, of red plums the market plans to order this year?
The amount of pounds of plum that is ordered this year will be:
= 15 1/2 × 1 1/4
= 31/2 × 5/4
= 19 3/8
Since they want 2/5 to be red plums, the total amount of red plums will then be:
= 2/5 × 19 3/8
= 2/5 × 155/8
= 310/40
= 7 3/4 pounds

solve: |2x-1| ≥ 4x+3
Step-by-step explanation:
consider the sign as equals then
move 2x right side 3 on left
solve it
answer is 2
Question is: 2x - 1 >= 4x + 3
First, join the like terms together.
-> So 2x moves into 4x, meaning it becomes negative -2x on the other side.
-> The number 3 moves into the other side which also becomes negative.
Now the equation will look like this:
- 3 - 1 >= 4x - 2x
- 4 >= 2x
Put 2 on the other side with - 4, and it will divide (not plus or minus as 2 was combined with an unlike term).
It looks like this now:
- 4/2 >= x
- 2 >= x
This is the answer.
Solving equations -3x + 7 = 28
Answer:
x = - 7

x = - 7
Answer: x = −7
Step-by-step explanation:
Step 1: Subtract 7 from both sides.
Step 2: Divide both sides by -3.
Final Answer: x = −7

The answer to the question is 540°
Step-by-step explanation:
The reason to the answer is:-
There is a formula which is (n - 2) × 180
n is the number of sides the shape has, and there is 5 sides so we subtract 5 - 2 = 3
Therefore, 3 × 180 = 540°

A shoe store purchases a pair of shoes for $75
before a mark up is applied.
There is a 140% markup. After the markup, a 6%
sales tax is added.
What is the total after discount and tax?
Answer:
$78.9
Step-by-step explanation:
Given data
We are told that the store purchased the shoe before mark up, hence we only need to solve for the tax
tax= 6%
=6/100*75
=0.06*65
=$3.9
Hence the total is
=75+3.9
=$78.9
