Answers
Answer:
Step-by-step explanation:
1
perimeter = 9 · 4 = 36 m
area = 9² = 81 m²
2
perimeter = (10+14) · 2 = 24 · 2 = 48 in
area = 10 · 14 = 140 in²
3
width = 63 : 7 = 9 km
9 · 2 = 18 km
7 · 2 = 14 km
area = 18 · 14 = 252 km²
4
A 300 : 30 = 10
(10 + 30) · 2 = 40 · 2 = 80 (no)
B
(20 + 5) ·2 = 25 · 2 = 50 yd (ok)
C
perimeter is 48 yd (ok)
D
(22 +26) · 2 = 48 · 2 = 96 yd (no)
E
(16 + 14) · 2 = 30 · 2 = 60 yd (no)
F
length = 162 : 9 = 18 yd
(18 +9) · 2 = 27 · 2 = 54 yd (ok)
Answer:
1
perimeter = 9 · 4 = 36 m
area = 9² = 81 m²
2
perimeter = (10+14) · 2 = 24 · 2 = 48 in
area = 10 · 14 = 140 in²
3
width = 63 : 7 = 9 km
9 · 2 = 18 km
7 · 2 = 14 km
area = 18 · 14 = 252 km²
4
A 300 : 30 = 10
(10 + 30) · 2 = 40 · 2 = 80 (no)

Brainlist for positive attitude and correct answer :D
Answers
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

A scuba diver is 15.5 feet below the surface of the water. If the diver continues to swim downward at a rate of 2.5 feet per second, what is her location, in feet, relative to the surface after 712 seconds? feet
Answers
The answers is: 33
33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.
Step-by-step explanation:
Given:
A scuba diver is 15.5 feet below the surface of the water.
The diver continues to swim downward at a rate of 2.5 feet per second.
Now, to find the integer represents her location relative to the surface after 7 seconds.
And to find how far does the diver have to go to return to the surface.
So, to get the integer represents her location relative to the surface after 7 seconds.
Initial depth = 15.5 feet.
Distance traveled down = 7 × 2.5 = 17.5 feet.
Final depth of water surface = Initial depth + Distance traveled down.
Final depth of water surface = 15.5 feet + 17.5 feet.
Final depth of water surface = 33 feet.
Thus, 33 is the integer represents her location relative to the surface after 7 seconds.
Now, to get how far does the diver have to go to return to the surface:
As, the diver goes to 33 feet down to the surface.
Thus, the diver to return she have to go through the same distance.
So, to return to the surface she need to go to 33 feet far.
Therefore, 33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.

According to the dot plot,
3 students spend 0.5 minutes brushing their teeth.
2 students spend 1.5 minutes brushing their teeth.
1 student spends 2.5 minutes brushing their teeth.
2 students spend 3.5 minutes brushing their teeth.
1 students spend 4 minutes brushing their teeth.
So, the number set will be: {0.5, 0.5, 0.5, 1.5, 1.5, 2.5, 3.5, 3.5, 4}
Median: The middle number in a set that is ordered from least to greatest.
In this example, the median is 1.5
Mean: The sum of all values divided by the number of values.
In this set there are 9 values so we’ll divide the sum by 9
In this example, the mean would be:
(0.5 + 0.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 4) ÷ 9
18 ÷ 9 = 2
If we compare the mean to the median we can see that the mean is greater because 2 > 1.5

Answers
Answer:
x = 10 units
Step-by-step explanation:
The formula for the area of a triangle of base x and height h is A = (1/2)(x)(h).
Here A = (1/2)(x)(8) = 40, so 8x = 80 and x = 10 units
If we look at this triangle we can see the straight line (the height). We want to use the height to figure out the side? Well divide 40 with the height (8). And now you get 5(cause 5*8 is 40. duh)

Answer:
m<8 = 110°
m<9 = 24°
m<10 = 46°
Step-by-step explanation:
m<9 = 180 - 110 - 46 - 24
Correct
m<8:
<8 and 110° angle are alternate interior angles of parallel lines cut by a transversal.
m<8 = 110°
<10 and 46° angle are alternate interior angles of parallel lines cut by a transversal.
m<10 = 46°
Answer:
Angle 8 = 110
Angle 9 = 24
Angle 10 = 46
Step-by-step explanation:
Sum of interior angle of a triangle is 180
Angle 9 + 110 + 46 = 180
Angle 9 + 156 = 180
Angle 9 = 180 - 156
Angle 9 = 24
The two lines are parallel which are represented by the arrows.
If two lines are parallel, then alternate interior angles are equal.
Here,
Angle 8 and 110 are alternate interior angles.
So,
Angle 8 = 110
Angles 8, 9 & 10 form a straight line.
So,
Sum of Angles 8, 9 & 10 is supplementary (i.e) 180
Angle 8 + Angle 9 + Angle 10 = 180
110 + 24 + Angle 10 = 180
134 + Angle 10 = 180
Angle 10 = 180 - 134
Angle 10 = 46
You can see that,
Angle 10 and 46 are also alternate interior angles.
So,
Angle 10 = 46

Match the base and height to the volume of the prism.
B = 6 square units
h = 12 units
Answers
We have a prism with a volume of 16y⁴ + 16y³ + 48y² cubic units.
Its volume is equal to the area of its base times its height.
Of course, for those to be the base area and height of this prism, they would have to multiply to 16y⁴ + 16y³ + 48y² cubic units.
Let's test each of these answers to see which gives us the correct volume.
--------------------------------------------------------------------------------------------------
a base area of 4y square units and height of 4y² + 4y + 12 units
We find the volume by multiplying the base area by the height...
4y(4y² + 4y + 12)
Distribute the 4y to each term inside the parentheses.
16y³ + 16y² + 48y
This is not the right volume, so these can not be dimensions of our prism.
--------------------------------------------------------------------------------------------------
a base area of 8y² square units and height of y² + 2y + 4 units
We find the volume by multiplying the base area by the height...
8y²(y² + 2y + 4)
Distribute the 8y² to each term inside the parentheses.
8y⁴ + 16y³ + 32y²
This is not the right volume, so these can not be dimensions of our prism.
--------------------------------------------------------------------------------------------------
a base area of 12y square units and height of 4y² + 4y + 36 units
We find the volume by multiplying the base area by the height...
12y(4y² + 4y + 36)
Distribute the 12y to each term inside the parentheses.
48y³ + 48y² + 432y
This is not the right volume, so these can not be dimensions of our prism.
--------------------------------------------------------------------------------------------------
a base area of 16y² square units and height of y² + y + 3 units
We find the volume by multiplying the base area by the height...
16y²(y² + y + 3)
Distribute the 16y² to each term inside the parentheses.
16y⁴ + 16y³ + 48y²
The volume fits, so these could be the base area and height of our prism.

D. a base area of 16y² square units and height of y² + y + 3 units
