Answer:
33 feet.
Step-by-step explanation:
If the ratio of the student to their shadow and flagpole to its shadow are equal, then you can use the proportion
5.5/3 = x/18 and cross multiply to find x.
5.5 × 18 = 99
3 × x = 3x
3x/3 = x, 99/3 = 33.
x = 33.
Answer: a. 90°
Step-by-step explanation:
We know that the in a circle, the measure of an inscribed angle is half the measure of the central angle with the same intercepted arc.
In the problem∠XYZ is the inscribed angle
∠XYZ=
⇒ ∠XYZ=
Since XZ is a diameter of the circle which is a line segment, thus ∠XZ=180°
∴ ∠XYZ=
∴ ∠XYZ=
Therefore, a. 90° is the measure of ∠XYZ.
Answer:
He makes 24,000 a year
Step-by-step explanation:
First figure out how much he makes a month without the extra $50 every day he works. which is $600, then add the 4 weeks (28 days) worth of the $50 every day, which is $1400, then add the $600 to get $2000 a month, then times that by twelve, which is $24,000.
Answer:
4 + 10x
Step-by-step explanation:
Simplify each term.
What I believe they are asking is to find which of those is the simplified quadratic formula. The quadratic formula is -b (plus or minus) (√b²-4ac) all divided by 2a.
This formula works when the equation is set up as ax²+bx+c
