Answer:
X=6
Step-by-step explanation:
To find the area of a triangle, you have to divide the multiplication by 2. So first, you would find 6 times what is 18. 3. But since thats the FULL answer, you multiply 3 by 2. 3 times 2 is 6! So x=6!

Answer:
it's a square so all 4 sides of perimeter equal 12 while every inside line is 6 sqrt/2
Step-by-step explanation:
there's triangles in the square that are symmetrical so each triangle has the same sides so using pythagorean theorem 6sqrt/2 ^2 + 6sqrt/2 ^2 = sqrt/C and C=12
Which two expressions are
equivalent?
A. (7.x) - 12 and (x-7) - 12
B. (x + 4) = 10 and x + (4 = 10)
C. 30. (x - 4) and 30 · (4 - x)

The length of a rectangle is 3 cm less than its width what are the dimensions of the rectangle if its area is 270 cm²
Given:
The length of a rectangle is 3 cm less than its width.
The area of the rectangle is 270 cm².
To find:
The dimensions of the rectangle.
Solution:
Let x be the width of the rectangle. Then,
[tex]\text{Length}=x-3[/tex]
Area of a rectangle is:
[tex]\text{Area}=\text{Length}\times \text{width}[/tex]
[tex]270=(x-3)(x)[/tex]
[tex]270=x^2-3x[/tex]
[tex]0=x^2-3x-270[/tex]
Splitting the middle term, we get
[tex]x^2-18x+15x-270=0[/tex]
[tex]x(x-18)+15(x-18)=0[/tex]
[tex](x-18)(x+15)=0[/tex]
[tex]x=18,-15[/tex]
Width of the rectangle cannot be negative. So, the only value of x is 18.
[tex]Width=18[/tex]
[tex]Length=18-3[/tex]
[tex]Length=15[/tex]
Therefore, the length of the rectangle is 15 cm and the width of the rectangle is 18 cm.
What is the median of the first half of the data? (first quartile)
Answer:
$273
Step-by-step explanation:
1. Find the first half of the list (There are 8 numbers in the list, so the first four)
2. List them from least to greatest ($196, $248, $298, $379)
3. find the middle of the numbers ($248, $298)
4. Since there are 2, we find the mean of the 2 numbers ($273)
5. So the answer is $273
At the beginning of 5th grade, Stephen was 48 inches tall. At the beginning of 8th grade he was 65 inches tall.
What is the percent of increase of Stephen's height?
A. 17.00%
B. 26. 15%
C. 35.42%
D. 73.85%
Answer:
35.42%
Step-by-step explanation:
Answer:
C. 35.42%
Step-by-step explanation:
65 - 48 = 17
Since he grew 17 inches, you must figure out what percentage 17 is of 48.
17/48 = 1/100 (represents decimal)
Cross multiply: 17 ⋅ 100 = 1700 and 48 ⋅ 1 = 48
Divide: 1700/ 48
= 35.41666666666667
Round to the nearest hundredth:
= 35.42
I have 5 paper clips, 8 push-pins and 12 erasers in my bag. Assuming that the odds for selecting paper clips, push-pins and erasers is the same, what is the probability that the item I pull out of the bag is NOT an eraser?
Answer:
the probability is 13/25
Step-by-step explanation:
5+8 = 13 and there are 12 erasers, 12 + 13 = 25. you have a 13/25 chance of not picking an eraser.
You start at (3, 0). You move right 1 unit and left 2 units. Where do you end?

Abby wants to ride her bicycle more than 70 miles this week. On Monday, Abby rode her bicycle for 25 miles. Abby plants to ride the same number of miles in the next six days. Write an inequality that can be used to determine the number of miles, m, that Abby will ride her bicycle each day to achieve her goal.
Answer:
25d > 70
Step-by-step explanation:
Abby wants to ride her bicycle more than 70 miles this week.
More than = >
On Monday, Abby rode her bicycle for 25 miles. Abby plants to ride the same number of miles in the next six days.
Let the number of days of week she would ride her bike = d
On Monday = 25 miles
And the rest of the week = The same = 25 miles
The inequality is written as:
25d > 70

Examine the diagram, where points B, C, D, and Elie on circle A. Angle BCD measures 57°. В. C A 570 D 2019 Strong Mind. Created using GeoGebra. What is mZBED?
Based on the inscribed angle theorem, the measure of angle BED in the diagram given is: 57°.
What is the Inscribed Angle Theorem?The inscribed angle theorem states the measure of the inscribed angles subtended by the same arc are the same.
∠BCD and ∠BED are subtended by the same arc BD.
Therefore, based on the inscribed angle theorem, we have:
m∠BCD = m∠BED = 57°.
m∠BED = 57°

An angle measures 56° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
118, 62
Step-by-step explanation:
We can set a system of equations where x and y are the two angles and x is the larger one
x+y=180
x-y=56
If we subtract the second equation from the first, we get 2y=124, simplifying that, we get y=62. Plugging it into either equation, we get x=118. We can check that 118 is 56 larger than 62, which it is. Thus, x=118, y=62.
The diameter of a circle is 4 cm. Find its area to the nearest tenth.
Answer:
10 cm²
Step-by-step explanation:
The radius of this circle is half the diameter hence is 2cm
Area of a circle is pi multiplied by the squared radius, i.e
Area = πr²
= 22/7 × 2 × 2
= 12.57 cm²
The nearest 10th is 10

Which graph shows the solution to this system of inequalities? y>-1/3x+1 y>2x-3
Answer:
Graph A.
Step-by-step explanation:
We don't even have to analyze the inequalities. It tells us that y is supposed to be bigger than something and that y is supposed to be bigger than something else. That means that for both lines, the shaded region must be upwards. The only graph that conforms to that is graph A.
