｡☆✼★ ━━━━━━━━━━━━━━ ☾
Answer:
It is x > -5
Step-by-step explanation:
Equation: -3x + 8 < 23
First, we have to move the constant to the other side. By moving it to the other side, the sign also changes becoming -3x < 23 - 8.
Now we simplify: 23 - 8 becomes 15
New equation: -3x < 15
Finally, we want the X by itself, and to do that, we must divide -3 to both sides. Keep in mind that when we multiply or divide, the sign '<' also changes.
[tex]\frac{-3x}{-3}[/tex]<[tex]\frac{15}{-3}[/tex] = x > -5

10 over 13 as a decimal rounded to the nearest tenth
Answer:
0.7
Step-by-step explanation:
If you divide 10 by 13 you get 0.76923 which rounded to the nearest tenth is 0.7
Hope this helped!
Answer:
0.8
Step-by-step explanation:
To find the decimal form of [tex]\frac{10}{13}[/tex] you'll need to divide 10 by 13.
10 ÷ 13 = 0.76923076923
The tenths decimal place is one to the right of the decimal: 0.1
Because the number after the tenths place is greater than or equal to 5, we will round the 0.7 up to a 0.8

Answer:
x =12
Step-by-step explanation:
We use the Pythagorean theorem
a^2 + b^2 =c^2 where a and b are the legs and c is the hypotenuse
x^2 + 5^2 = 13^2
x^2 +25 =169
Subtract 25 from each side
x^2 +25-25=169-25
x^2 = 144
Take the square root of each side
sqrt(x^2) = sqrt(144)
x = 12

Answer:
The measure of the hypotenuse is 25.
Step-by-step explanation:
To solve, we can use the Pythagorean theorem a² + b² = c² where,
a = 7
b = 24
(7)² + (24)² = 625
We have to take the square root of 625 to get our answer.
[tex]\sqrt{625} = 25[/tex]
Answer:
25
Step-by-step explanation:
This is a right triangle. This is because of the little square in the corner that indicates a right angle. Therefore, we can use the Pythagorean Theorem.
a^2+b^2=c^2
where a and b are the legs, and c is the hypotenuse.
We know that 7 and 24 are the legs, because they make up the right angle. We know c is the hypotenuse because it is opposite the right angle.
7^2+24^2=c^2
Evaluate the exponents on the left side.
49+576=c^2
Add 49 and 576
625=c^2
Since c is being squared, take the square root of both sides. This will cancel out the exponent, and leave c by itself.
√625= √c^2
√625=c
25=c
The measure of the hypotenuse is 25
The diameter of a circle measures 8 cm. What is the circumference of the circle?
Use 3.14 for it, and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
16π or 50.266
Step-by-step explanation:
Circumference formula is just 2πr ,and the radius is 8, so just sub into the formula
Answer: 25.12 cm
Step-by-step explanation:
The formula for the circumference of a circle is [tex]2\pi r[/tex], when r = the radius.
Diameter = 2 x radius = 8 cm. Therefore, the radius = 4 cm.
Plug r = 4 cm in to the circumference formula: [tex]2\pi (4)[/tex] = 8 x 3.14 = 25.12 cm.

Answer:
To find the Median arrange the data in order from least to greatest then find the middle number. To find the middle number cross of one from the front and one from the bcak. If there are 2 numbers left in the middle add those numbers together and them divided the sum by 2.
The mean is the average of the numbers. It is easy to find. First, add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Answer:
Equal, equal, not equal, not equal
Step-by-step explanation:
A) Equal, because they have the same height and base. To find the area of a triangle, you use "(b+h)/2". In this situation, the "b" and the "h" are equal.
B) Equal, as they also have the same height and base. To find the area, you use b*h, and they are equivalent.
C) Not equal. The two lengths given are not equal.
D) Not equal. The two triangle's heights are equal, but their bases are not. If you look at the second triangle, you can see that if is further from the triangles' intersections. This means that the base is larger than the one on the left.

Given: m arc AB = 4x, m arc BC = 3x
m arc CD = 2x, m arc DA = 3x
Find: m∠APB
Answer:
a > m/bp
Step-by-step explanation:
flip the equation
abp > m
divide both sides with bp
abp/bp > m/bp
a > m/bp
Answer:
m<APB = 30 degrees
Step-by-step explanation:
The sum of angles in a circle is 360 degrees. Add up all the arcs to get the equation : 4x+3x+2x+3x=360 degrees.
x is equal to 30 degrees
m arc AB = 4x = 120 degrees
m arc DC = 2x = 60 degrees
By secants exterior angles, m<APB = 1/2(m arc AB - m arc DC) = 1/2(120-60) = 30 degrees.
The answer is m<APB = 30 degrees
