Step-by-step explanation:
Let's solve your equation step-by-step.
v2+11v−26=0
Step 1: Factor left side of equation.

since there are 5,280 feet in one mile and 3.3 feet in one meter how many meters per second are equivalent to 50 miles per hour
Answers
Given:
1 mile = 5280 feet
1 meter = 3.3 feet
convert 60 miles per hour to meters per second
60 miles to meters
60 miles x 5280ft x 1meter = (60*5280m)/3.3 = 316800m/3.3
1 mile 3.3ft
= 96,000 meters
1 hour to seconds
1 hour x 60 minutes x 60 seconds = 1 * 60 * 60sec = 3600 seconds
1 hour 1 minute
unit rate: meters per second
96000 meters ÷ 3600 seconds = 26 2400/3600
simplify 26 2400/3600 ⇒ 26 2/3 meters per second
2400 ÷ 1200 = 2
3600 ÷ 1200 = 3

The measure of the supplement of ∠BAC is (18x+22) degrees. The measure of the complement of ∠BAC is (9x-5) degrees. Determine m∠BAC.
Answers
Answer:
∠ABC = 32°
Step-by-step explanation:
We know that the two angles are termed as supplementary when their angle measures add up to 180 degrees.Given that the measure of the supplement of ∠BAC is (18x+22) degrees.
so
∠ABC + (18x + 22)° =180°
∠ABC + 18x =180°-22°
∠ABC + 18x =158°
∠ABC = 158° - 18x ----[Equation A]
We know that the two angles are termed as complementary when their angle measures add up to 90 degrees.Given that the measure of the complement of ∠BAC is (9x-5) degrees.
so
∠ABC + (9x-5)° =90°
∠ABC + 9x =90°+5°
∠ABC + 9x =95°
∠ABC = 95° - 9x ----[Equation B]
Equating [Equation A] and [Equation B]
158° - 18x = 95° - 9x
-18x+9x = 95° - 158°
-9x = -63
divide both sides by -9
x = 7
Now, substituting the value x=7 in the [Equation A]
∠ABC = 158° - 18(7)
= 158° - 126°
= 32°
Thus,
∠ABC = 32°

“ Triangle A has side lengths 3,4 and 5 . Triangle B has side lengths 6,7 and 8 “
“1. Explain how you know that triangle B is not similar to triangle A”
“2. Give possible side lengths for triangle B so that it is similar to triangle A”
Answers
Answer/Step-by-step explanation:
A. Given that ∆A has side lengths 3, 4, and 5, that corresponds to the side lengths 6, 7, and 8 of ∆B, both ∆s can only be similar to each other if the ratios of their corresponding side lengths are equal.
Thus:
[tex] \frac{3}{6} [/tex] ≠ [tex] \frac{4}{7} [/tex] ≠ [tex] \frac{5}{8} [/tex] .
✅The ratio of their corresponding side lengths is not equal, therefore, triangle B is not similar to triangle A.
B. To get the possible side lengths for triangle B to make it similar to triangle A, simply multiply each side length of triangle A by a scale factor.
Let's use a scale factor of 2.
3 × 2 = 6
4 × 2 = 8
5 × 2 = 10.
✅Possible side lengths for triangle B that will make it similar to triangle A are: 6, 8, and 10.

The statement that described the areas and perimeters of the figures should be that they have different areas and different perimeters.
What is the perimeter?The perimeter refer to the closed path where it is surrounded, outlines for the two-dimensional shape for the one-dimensional length.
So here the perimeter of a circle should be known as the circumference.

System A should be solved by elimination because you can easily cancel out the 3m to solve.
System B should be solved by substitution. Since the an equation for the y value is given, you can easily substitute it into the other equation.
System C should be solved by graphing. You don't have to worry about any slopes or intercepts to graph. You can graph it using only whole numbers.
Which inequality best represents that ice cream at −3°C is cooler than ice cream at 1°C? (4 points)
a
−3°C > 1°C
b
−3°C 3°C
d
1°C < −3°C
Answers
Answer:
-3° C < 1°C is the correct option.
Step-by-step explanation:
As we know that:
The inequality symbol '<' means 'less than'.The inequality symbol '>' means 'more than'.If someone says that something is cooler than the other thing, it indicates that it is lesser than the other based on its temperature.
As the ice cream at −3°C is cooler than ice cream at 1°C, it indicates that temperature -3° C < temperature 1°C.
Therefore, -3° C < 1°C is the correct option.
