One angle of an isosceles triangle measures 92°. What measures are possible for the other two angles? Choose all that apply.44 24 76 47
Answer:
44
Step-by-step explanation:
First remmember that all triangles will add up to equal 180 degrees
so we will have to subtract 180 by 92
whitch is 88
Now sence an isoclies are to equal sides we will have to divide 88 by 2

Answer:

Step-by-step explanation:
Problem-1:
[tex] {x}^{ \frac{2}{7} } [/tex]
remember that,
[tex]\displaystyle {x}^{ \frac{a}{b} } = \sqrt[b]{ {x}^{a} } [/tex]
here,
a=2b=7hence,
[tex] {x}^{ \frac{2}{7} } = \boxed{\sqrt[7]{ {x}^{2} } }[/tex]
Problem-2:
recall that,
[tex] \sqrt[n]{x} = {x}^{ \frac{1}{n} } [/tex]
therefore,
[tex] \sqrt[3]{2y} = (2y {)}^{ \frac{1}{3} } \implies \boxed{{2 }^{ \frac{1}{3} } {y}^{ \frac{1}{3} } }[/tex]
A 12-foot ladder is leaning against a wall. The bottom of the ladder is 5 feet away from the bottom of the wall.
Approximately how high up the wall does the top of the ladder reach?
Answer:
10.9 units
Step-by-step explanation:
Let the hight of the wall be " x ".
( Height = x )
Here,
12 foot ladder is the hypotenuse side.
( Hypotenuse = 12 )
5 feet away is the base side.
( Base = 5 )
Formula : -
Height² + Base² = Hypotenuse²
x² + 5² = 12²
x² + 25 = 144
x² = 144 - 25
x² = 119
x = √119
x = 10.9 approximately
Therefore,
High up the wall does the top of the ladder reach is 10.9 units.
A cube is a regular prism with square faces. How can you write a simpler version of the surface area formula for a cube?
Answer:
A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.
The surface area formula for a cube is 6l²
How to determine the surface area?A cube has the following features:
6 faces of equal areasEach face has equal side lengthThe area of a face of a cube is:
Area = l²
Where l represents the side length
The surface area formula for a cube is then calculated using:
Surface area = 6 * Area of a face
So, we have:
Surface area = 6 * l²
Surface area = 6l²
Hence, the surface area formula for a cube is 6l²

3. Look at the set of ordered pairs below. Determine if the three statements that follow are true or false.
If it is true, explain why you know that it is true.
If it is false, explain why you know that it is false and change the statement to a true statement.
{(3,6), (4,6), (5,7), (6,8), (7,10), (8,10)
Statement 1:
The relation is not a function because every y-value has more than one corresponding X-value
Statement 2:
The domain of this relation is 3=< x =< 8.
Statement 3:
The range of this relation is {6, 7, 8, 10}
Answer:
Statement 1 - false
A function is one-to-one or many-to-one.
One-to-one means each value in the range (y-values) corresponds to exactly one value in the domain (x-values)
Many-to-one means some values in the range (y-values) correspond to more than one (many) value in the domain (x-values).
Therefore, as some y-values correspond to more than one x-value, this is a many-to-one function.
The true statement should be:
The relation is a function because some y-values correspond to more than one x-value.
Statement 2- true
The domain is the set of input values (x-values). Therefore, the domain is 3 ≤ x ≤ 8 as the smallest x-value is 3 and the highest x-value is 8.
Statement 3 - true
The range is the set of output values (y-values). Therefore, the range is {6, 7, 8, 10} as these are the y-values of the ordered pairs.

Mrs. Nigrini picks up some grapefruits that each weigh 1/2 pound. When she checks out she finds her bag of grapefruit weighs exactly 6.5 pounds. Each grapefruit costs $1.29. How much did she spend on grapefruit?
Answer:
$16.77
Step-by-step explanation:
1. Grapefruit cost 1/2 pound = 0.5 pound
2. Since the bag weighs 6.5 pounds, you can do 6.5/0.5 to find the number of grapefruits
3. 6.5/0.5 = 13
4. The total cost of the grapefruits would be $1.29 * 13 = $16.77

what is an equation of the line that passes through the point (-2,-8) and has a slope of 3?
a) y=3x-2
b) y=3x-22
c) y=3x+2
d) y=3x+22
Answer:
y = 3x -2
Step-by-step explanation:
General equation of a line in the slope intercept form is
y = mx + b ,
where m is the slope and b is the y-intercept ( where intercepts the y-axis)
y = 3x + b ,
because is given slope is m = 3
For point (x = -2, y = -8) we have
-8 = 3 (-2) + b
-8 = -6 + b
-8 + 6 = b
-2 = b
The equation of the line that passes through the point (-2,-8) and has a slope of 3 is
y = 3x -2
If the slope of a line is -6, does the line rise (from left to right), fall (from left to right), horizontal or vertical?
Answer:
it falls left to right horizontal
pls give brainlyist
Step-by-step explanation:
Answer:
The line will fall (from left to right).
Step-by-step explanation:
If the slope of any line is negative then that line will go downwards or fall (from left to right). While if the slope were to be positive, that would mean the line will rise (from left to right).

Two theorems we are proving are:
Line drawn from the center of the circle to bisect a chord is perpendicular to it.Perpendicular drawn from the center of the circle to a chord, bisects it.How do we solve the given question?Part A: The image is attached
Part B:
Let there be a circle with the center at O. Let AC be a chord. Let OE be a radius of the chord such that OE bisects AC at B, that is, AB = BC.
To prove: A line drawn from the center of the circle to bisect a chord is perpendicular to it.
Construction: We join OA and OB.
Proof:
In ΔOAB and ΔOCB,
OA = OC (Radius of the same circle)
AB = BC (Given, at B, the chord is bisected)
OB = OB (common side)
∴ ΔOAB ≅ ΔOCB [SSS axiom]
∴ ∠OBA = ∠OBC [Common parts of Congruent triangles]
Let ∠OBA = ∠OBC = x.
Since AC is a straight line,
∠OBA + ∠OBC = 180° [Linear pair]
or, x + x = 180°
or, 2x = 180°
or, x = 90°.
∴ ∠OBA = ∠OBC = 90°.
So, we can say that OB ⊥ AC, hence the theorem is proved.
Part C: The image is attached
Part D:
Let there be a circle with the center at O. Let AC be a chord. Let OE be a radius of the chord such that OE is perpendicular to AC at B, that is, AB ⊥ BC.
To prove: A line drawn from the center of the circle perpendicular to the chord bisects it.
Construction: We join OA and OB.
Proof:
In ΔOAB and ΔOCB,
OA = OC (Radius of the same circle)
∠OBA = ∠OBC = 90° (∵ OB ⊥ AC)
OB = OB (common side)
∴ ΔOAB ≅ ΔOCB [RHS axiom]
∴ AB = AC [Common parts of Congruent triangles]
So, we can say that OE perpendicular to the chord AC bisects it, hence the theorem is proved.

The depth of two lakes is measured at multiple spots. For the first lake, the mean depth is about 45 feet with a mean absolute deviation of 8 feet. For the second lake, the mean depth is about 60 feet with a mean absolute deviation of 27 feet.
Noah says the second lake is generally deeper than the first lake. Do you agree with Noah?
No, I do not agree with Noah because the second lake has greater variability with a higher MAD so even though the mean depth is deeper the data is very spread out away from that mean.
No, I do not agree with Noah. The MAD tells us how deep it is and the 1st MAD is more.
Yes, I agree with Noah. The MAD tells us how deep it is and the second MAD is more.
Yes, I agree with Noah because the first lake has a smaller mean and MAD than the second.

Yes, I agree with Noah because the first lake has a smaller mean and MAD than the second
