The measure of one angle of a right triangle is 44º more than the measure of the smallest angle. Find the measures of all
three angles.

You are given that all three sides of both the triangles are "approximately equal"

This means the answer is D. SSS (Side-Side-Side)

It can't be A. because S-A-S means side-angle-side and these are not the "givens"

It can't be B. because A-S-A means angle-side-angle and these are not the "givens"

It can't be C. because A-A-A means angle-angle-angle and these are not the "givens"

Hope this helped!

Answer:

D

Step-by-step explanation:

Circle C and D both have a radius of 7.  So the sum of their areas is:

A = π(7)² + π(7)²

A = 98π

Answer:  The correct option is

(D) 98π units².

Step-by-step explanation:  We are given to find the sum of the areas of circle C and circle D.

From the figure, we note that

both the circle s C and D have equal radii given by

r = 7 cm.

Also, we know that the area of a circle with radius r units is given by

[tex]A=\pi r^2.[/tex]

Therefore, the sum of the area of circle C and D is given by

[tex]S=2A=2\pi r^2=2\times \pi\times7^2=2\times49\pi=98\pi~\textup{sq. units}.[/tex]

Thus, the required sum of the areas is 98π units².

Option (D) is CORRECT.

Nathan is walking faster than Matt.

The graph shows that for every hour, Matt walks 3 miles, since it goes to the right 1 and up 3 over and over again.  This means Matt's speed is 3 miles per hour.

4 miles per hour is greater than 3 miles per hour, so Nathan is walking at a faster speed.

Answer:

0.8

Step-by-step explanation:

Let's say s is the side length of the square.  When the square is cut diagonally, each triangle has a base of s and a height of s.

Area of a triangle is:

A = ½ bh

Given A = 0.32, b = s, and h = s:

0.32 = ½ (s)(s)

0.64 = s²

s = 0.8

The side length of the square is 0.8 units.

The side length, in units, of the original square is 0.8 units.

A square is a two-dimensional shape that is made up of four equal sides. The diagonal is a straight line that divides the square into two right triangles.

The area of a triangle = 1/2 x base x height

0.32 = 1/2 x s²

0.32 x 2 = s²

0.64 = s²

s = √0.64

s = 0.8 units

Answer:

y=1/10x +10

Step-by-step explanation:

when we replace the x in this equation with numbers representing x in the points given, we are going to end up with the points that represents y in the question.

Answer:

C. [tex]y=\frac{x}{10} +10[/tex]

Step-by-step explanation:

Here we are given two points from which the line passes through . hence we use the two point form to evaluate the equation of line.

The two points are

(0,10) and (10,11)

the two point formula is

[tex]\frac{y-y1}{x-x1} = \frac{y2-y1}{x2-x1}[/tex]

Here x1=0, x2=10, y1=10, y2=11

Now we keep these values in the two point form formula given above

[tex]\frac{y-10}{x-0} = \frac{11-10}{10-0}\\\frac{y-10}{x} = \frac{1}{10}\\y-10=\frac{x}{10}\\y=\frac{x}{10}+10[/tex]

Hence our third option is correct.

Answer:

  least to greatest: {61, 61, 61, 178, 179}

Step-by-step explanation:

If the third-largest angle is 61°, the smallest three angles cannot be larger than 183°. Since the total of all angles must be 540°, and the total of the largest two cannot be greater than 179°×2 = 358°, the sum of the smallest three must be at least 540° -358° = 182°.

So, the possible sets of angles with the smallest 3 totaling 182° or 183° are (in degrees) ...

Step-by-step explanation:

The rules of logarithms tell you ...

When your log is log₁₀ and a=M and b=N, this becomes ...

  log₁₀(MN) = log₁₀(M) + log₁₀(N)

Some functions are not always written with their arguments in parentheses. I believe it avoids ambiguity to put function arguments in parentheses, so I have done that here. It appears your answer form may want you to write ...

  log₁₀M+log₁₀N . . . . . I don't recommend this form

Answer:

  The function is even.

Step-by-step explanation:

Compare it to the definition of an odd function or an even function.

Odd function: if (x, y) is in the relation, then (-x, -y) is also in the relation. (The function is symmetrical about the origin.)

Even function: if (x, y) is in the relation, then (-x, y) is also in the relation. (The function is symmetrical about the y-axis.)

__

The first point listed is (1, 2). If this function is odd, we expect to find (-1, -2). There is none such.

If this function is even, we expect to find (-1, 2). That is the third point listed, so it is possible this function is even. Comparing the other points to their even-function counterparts shows all of them match the definition of an even function.

The correlation coefficient 'r' equals 0 indicates that there is no linear relationship between two variables. However, there could be a non-linear relationship present that is not captured by 'r'. Therefore, one should also consider other statistical tests or data visualization methods to fully understand the relationship between variables.

When a correlation coefficient, or 'r', equals 0, it conveys that there is no linear correlation between the two observed variables. However, this does not necessarily mean that the two variables are entirely unassociated. The correct answer to the student's question is B: No, because while there is no linear correlation, there may be a relationship that is not linear.

This means that in the context of the problem, just because 'r' equals 0 between student's body temperature and head circumference, it doesn't conclude there is no relationship between these two variables. There could be a non-linear or curve relationship present, which cannot be determined by the correlation coefficient.

Remember, the correlation coefficient 'r' only measures the strength and direction of a linear relationship between two variables. It doesn't help in determining non-linear relationships. Therefore, it's important to also consider other statistical tests or visual data assessment methods when analyzing associations between variables.

Answer:

True

Step-by-step explanation:

Based on Angle-Angle-Side, you would have two congruent triangles and those two sides are equal/congruent.

It is true, from the given information only we can say that AD = CD.

In geometry, two figures or objects are congruent if their shape and size are same.

If two angles and a side which does not come between these two angles is congruent with two angles and a side which does not come between these two of another triangle, then the triangles are said to be congruent by AAS criterion.

In the given question

∠ABD = ∠CBD  ( Given)

∠BAD = ∠BCD   (Right angles)

    BD = DB        (Common side of both triangles)

Δ ABD ≅ Δ CBD (AAS criterion)

The two triangles are congruent hence AD = CD.

Answer: [tex]=528[/tex]

Step-by-step explanation:

You have this expression:

[tex]2(3x^3 + 2y^2)[/tex]

You already know that the value of the variable "x" is:

[tex]x=-2[/tex]

And the value of the variable "y" is:

[tex]y=12[/tex]

Therefore, you can substitute the value of the variable "x" and the value of the variable "y" into the expression.

Then you get:

 [tex]2(3(-2)^3 + 2(12)^2)=2(-24+288)=2(264)=528[/tex]

Answer:

528

Step-by-step explanation:

2(3х³ + 2у²)

Where x = -2 and y = 12 which means whenever you sees x, put -2 in replacement and y put 12

So we solve;

2(3x³ + 2y²), x = -2, y = 12

2[3(-2)³ + 2(12)²]

2[3(-8) + 2(144)]

Answer:

a) AB = 17 m

b) AC = 20.8 m

Step-by-step explanation:

Pythagorean theorem

a^2 + b^2 = c^2

a)

AB^2 = (26-11)^2 + 8^2

AB^2 = 15^2 + 8^2

AB^2 =  225 + 64

AB^2 = 289

AB = 17 m

b)

AC^2 = AB^2 + BC^2

AC^2 = 17^2 + 12^2

AC^2 =289 + 144

AC^2 = 433

AC = 20.8 m

Answer: (√2 - √6)/4

Answer:

B.  

Step-by-step explanation:

The parabola opens to the right since the focus is to the right of the vertex.  So the square part will definitely contain a y.  By elimination the answers can't be A or C.  The vertex is (2,3) so the answer is B.

Longer answer:

formula to use is (y-k)^2=4p(x-h) where the vertex is (h,k)

So (2,3) is our vertex so enter it in giving

(y-3)^2=4p(x-2)

p is 5 since 2 and 7 are 5 units apart

p is positive because again focus is right of vertex

the answer is

(y-3)^2=20(x-2)

Answer:

B

Step-by-step explanation:

Substitute a point in the equation:
