Answer:

It is an acute triangle.

Two sides have the same length.

The third angle measures 70°.

Step-by-step explanation:

It is an acute triangle because all triangles are less than 90°.

Two sides have the same length because since we know that two angles, which would be the base angles are the same, then triangle must be isosceles.

180°-(40°+70°)= 110°

Answer:

BE

Step-by-step explanation:

This is because it is the part of a line that has two endpoints and is finite in length.

Answer: 2550

Step-by-step explanation:

it literally says it in the question

part a: –2°F > –6°F

part b: the inequality is representing the temperatures of city R and city S, comparing the difference in their temperatures.

part c: (marking city R at –2 on the number line and marking city S at –6 on the number line), using the number line to show the values of the city temperatures, city R is warmer because it is closer to 0 while city S is farther from zero and in the case that these are negative temperatures, the temperature closest to zero is the warmest.

Answer:

1,256 dm^2 and 400π dm^2

Step-by-step explanation:

The circumference is equal to 2pi times the radius. So 40pi=2pi times the radius so the radius is 20. The area of a circle is pi times the radius squared or 400pi and if using 3.14 for pi this would be 1,256 dm^2

Answer:

Explanation:

Answer:

The mean is 7.61.

The median is 7.31

There is no mode

Step-by-step explanation:

4.7+8.51+6.5+7.42+9.64+7.2+9.3 = 53.27

53.27/7 = 7.62

( 7.42 + 7.2 ) / 2 = 7.31

Have a great day! :)

Answer:

The mean should be 12.55

Answer:

vowel = 2/5

even number = 4/9

Step-by-step explanation:

vowel:

total of all letters in the box= 5

cound total number of vowels in the box = 2

[tex]\frac{2}{5}[/tex] because out of the 5 letters there is 2 vowels so overall you have a [tex]\frac{2}{5}[/tex]chance of pulling out a vowel.

Same logic for the even numbers one.

Even numbers:

total amount of numbers in the box: 9

total amout of even numbers: 4

[tex]\frac{4}{9}[/tex] because you have 9 numbers in total and you want the chnce of finding an even number. That means you need to put the amout of even numbers on top of the fraction and the total amount below.

OVERALL:

simple way of remembering it is:

p = total amout of the thing you want the probability of finding (in this case even numbers or vowels)

t = total amout of all options in the box (or any container)

[tex]\frac{p}{t}[/tex]

Answer:

[tex]144 in^{2}[/tex]

Step-by-step explanation:

We can see in the figure that you have 4 triangles, all congruent, and 1 square in the middle. The measure of the square is 8x8, so first find the area of that, 64. Then, we only need to find the area of 1 triangle and multiply that by 4, as you have 4 triangles in the figure. The area of a triangle is (base×height)/2 so fill in the values. The base is 8 in, and the height is 5 in. 5×8 is 40, so we divide that by 2 and get 20. Then multiply this by 4, and you get 80. Now, take your original area of the square, and add it to the area of the 4 triangles. 64+80=144

Hope this helps!

Answer: 108 ft³ 

Step-by-step explanation:

V= 4/3πr³ 

Facts:

Pi= 3

Diameter = 6

Step1; find the radius

Diameter is the length acaross the whole circle, but the radius is just 1/2 the circle. Therefore, if the diameter is 6, then the radius can be found by finding 1/2 of 6.

1/2 of 6= 1/2x6= 3.

R= 3

Step 2:  Plug in the numbers (into the formula)

PEMDAS

(exponents go first)

(then multiply from left to right)

V= 4/3πr³ 

V= 4/3x3x3³ 

V= 4/3x3x (3x3x3)

V= 4/3x3x27

V= (4/3x3)  x 27

V= 12/3x27

V= 4x27

V= 108

Volume= 108 ft³ 

Hope this helps :)) Also brainliest would be appreciated, i worked pretty hard on this thanks! :)

Answer:

e = 126

Step-by-step explanation:

Both triangles are isosceles triangles. Therefore in the smaller triangle, there are two angles that are equal to 42 degrees (the other one is next to e)

42 + 42 = 84

there are 180 degrees in a triangle

180 - 84 = 96

So the last angle in the triangle (The little one) is equal to 96 degrees.

The rule for cyclic quadrilaterals is that the two opposite angles equal 180. So the angle opposite 96 degrees will be equal to:

180 - 96 = 84

As the larger triangle is also an isosceles (as mentioned above), two angles will be equal to each other. The two angles that are equal are at the bottom left. As one of them is equal to 84, the other is also equal to 84. This means the last angle (the one at the top) is equal to:

180 - (84 + 84) =

180 - 168 = 12

Angles on a straight line always equal 180 degrees. So 'e' is equal to 180 minus the other two triangle angles on the line they all share.

180 - (12 + 42) =

180 - 54 = 126

Therefore e = 126

Answer: 5 with an open circle facing the right.

Step-by-step explanation:

First: you need to know the difference between closed and open circles. Closed means less than or equal to/ greater than or equal to while an open circle just means less than/ greater than.

Second: To know if it will be facing left or right is very simple. It is just if the number is increasing or decreasing in your problem. If increasing it goes right if decreasing it goes left. In this case, the number increases each day so it will face the right.

Third: To start the problem you subtract the number of shells she has already (34) by how many she needs (100) which is 66. then divide 66 by the number of seashells they get a day (12) which would give you 5.5

Fourth: I'm going to guess that you can't do decimals on the graph so all you have to do is put an open circle with the arrow facing the right meaning everything after this point, not including the number it is on.

Answer:

d  ≥  7

Step-by-step explanation:

A closed dot means you CAN use the number in the equality (greater than and equal to or less than and equal to). An OPEN dot means it's just greater than or less than, no equal to. Positive numbers GROW to the right so if the line is going that way it means greater than or greater than and equal to. The same is true for the left side. The left side makes numbers get SMALLER which means less than or less than and equal to. Your problem has a closed dot and an arrow to the right so the inequality is d  ≥  7.

Answer:

4 books

Step-by-step explanation:

Our problem here is:

[tex](3.95)3+8.95b=47.65[/tex]

So we have to find B, and that will be our answer (the number of books).

1. Simplify the expression

[tex]3.95\cdot 3+8.95x=47.65[/tex]

Combine like terms:

[tex]11.85+8.95x=47.65[/tex]

2. Group all constants on the right side of the equation

[tex]11.85+8.95x=47.65[/tex]

Subtract  from both sides:

[tex]11.85+8.95x-11.85=47.65-11.85[/tex]

Group like terms:

[tex]8.95x+11.85-11.85=47.65-11.85[/tex]

Simplify the arithmetic:

[tex]8.95x=47.65-11.85[/tex]

Simplify the arithmetic:

[tex]8.95x=35.8[/tex]

3. Isolate the x

[tex]8.95x=35.8[/tex]

Divide both sides by 8.95:

[tex]\frac{8.95x}{8.95}=\frac{35.8}{8.95}[/tex]

Simplify the arithmetic:

[tex]x=\frac{35.8}{8.95}[/tex]

Simplify the arithmetic:

[tex]x=4[/tex]

Answer: P= 2640 dam

or 264 hm

or 26.4 km

Step-by-step explanation:

See picture of all side values in the three measurement forms

Answer: I think this is right but I'm not 100 percent sure

26.4 km, 264 hm, 2640 dam

Step-by-step explanation:

Well, permitter is adding all lengths together.

Which is 5 km + 62 hm + 62 hm + 900 dm

Assuming hm stands for Hectometer, I will divide 62/10 = 6.2

Now we are left with the equation 5 km + 6.2 km + 6.2 km + 900 dam

Since 100 dm = 1 km, we will divide 900 dm by 100 which is 9 km

Lastly, we are left of with:

5 + 6.2 + 6.2 + 9 = 26.4 km

Now I will quickly covert everything into the other 2 measurements

26.4 km = 264 hm (10x)

26.4 km = 2640 dam (100x)

Answer:

1 1/27 = 28/27

Step-by-step explanation:

First you evaluate your parenthesis, and to do that you need to find the Least Common Denominator of 2/3 and 2/9. The least common denominator would be 9. 3 x 3 = 9 so you multiply 2 x 3 = 6. 6/9 - 2/9 = 4/9. 7/3 x 4/9

7 x 4 = 28

3 x 9 = 27

28/27 = 1 1/27

Hey there!

7/3 * (2/3 - 2/9)

= 7/3 * 4/9

= 7(4) / 3(9)

= 28 / 27

≈ 1 1/27

Therefore, the answer should be:

28 / 27

OR

1 1/27

Either should work because they are both equivalent to each other.

Good luck on your assignment & enjoy your day!
