Answer:
D
Step-by-step explanation:
The Triangle Sum theorem states the angles of all triangles will add up to 180.
70 + 50 + 70 = 190. Therefore, this cannot be a triangle.
add to both sides: add what to both sides 8+1/9x+ =-4+
Answer:
Step-by-step explanation:
Now add - x to both sides by the addition rule. Remember, adding the same quantity to both sides of an inequality does not change its direction.

PLSSS HELP ANSWER, THE QUESTION IS IN THE SCREENSHOT
Since the room temperature is 22 degrees Celsius,
[tex]\frac{dT}{dt}=k(T-22)[/tex]
Solving the differential equation,
[tex]\frac{1}{T-22} dT=k dt \\ \\ \int \frac{1}{T-22} dT=\int k dt \\ \\ \ln|T-22|=kt+C[/tex]
When t=0, the temperature is 100 degrees.
[tex]\ln 78=C \\ \\ \implies \ln|T-22|=kt+\ln 78[/tex]
When t=1, the temperature is 80 degrees.
[tex]\ln 58=k+\ln 78 \implies k=\ln(29/39) \\ \\ \implies \ln|T-22|=t \ln(29/39)+\ln 78[/tex]
Setting t=4,
[tex]\ln|T-22|=4\ln(29/39)+\ln 78 \\ \\ T=22+e^{4\ln(29/39)+\ln 78} \approx \boxed{46}[/tex]

what are the smallest values of p and r that satisfy the definitions for parallel lines and perpendicular lines?
Answer:
p = 2
r = 4
Step-by-step explanation:
If you're doing parallel it needs to be like "side by side." The least you can do is 2 because you'll need at least one other line to be beside the original.
Perpendicular lines are intersecting, so if you intersect them as a plus sign, you'll make at least four right angles.

Can someone help me figure out what is 5/12 of 1 ⅓ =
Answer:
Gotta multiply them
Step-by-step explanation:
Answer:
5/9
Step-by-step explanation:
Of is another word for multiplication in math.
This means that to solve this, we will do:
5/12 × 1 ⅓
Make them both improper fractions
5/12 × 4/3
Multiply there numerators and denominators
20/36 =
5/9
What is the slope of the line that passes through the points(-4, 0) and (2, 0)?
Write your answer in simplest form.
Given:
Two points are (-4, 0) and (2, 0).
To find:
The slope of the line that passes through the given points.
Solution:
The line passes through the points (-4, 0) and (2, 0). So, the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{0-0}{2-(-4)}[/tex]
[tex]m=\dfrac{0}{2+4}[/tex]
[tex]m=\dfrac{0}{6}[/tex]
[tex]m=0[/tex]
Therefore, the slope of the line that passes through the points (-4, 0) and (2, 0) is 0.
D 3b. Triangle A has an area of 30cm² and a height of 5. What is the base?
The base of triangle will be 12 cm.
WHAT IS TRIANGLE ? HOW TO FIND ITS AREA ?A triangle is a three-sided polygon.
The area of a rectangle is commonly known to be b*h, where b is the base and h is the height. Using the formula for a rectangle, we can get the area of a triangle.
A rectangle is split into two congruent triangles by a diagonal. The area of each triangle is equal to half the size of the rectangle.
As a result, the triangle's area A may be calculated using the equation A=1/2*b*h, where b denotes the triangle's base and h its height.
CALCULATIONAREA OF TRIANGLE = 1/2*b*h
base = area of triangle * 2 / h
= 30 * 2 / 5
= 12 cm.
