Can someone pls help? The stuff in the box is n’t right. Please help!

Answers

Answer 1

Answer:

fixed amount is 150

the rate is 6

The formula to calculate the total cost of the caterer is

total cost = 150 × 6 + number of students

Step-by-step explanation:

1. 1050= 150×r+f

2. 750= 100×r+f

• On number 2 you substract on both sides f so you get 750-f=100×r with this you divide on both sides 100 and you get 7,50 -f÷100=r

• Now you can put r into term of number 1 and you get 1050=150x(7,50-f÷100)+f

• If you calculate this to just get a f on one side you get f=150 so this the fixed amount

• Put f in r=7,50-f÷100 so u get r=7,50-150÷100 or r=6 this the rate

• So the formula to calculate the total cost for the caterer is

total cost=150 + 6 × number of students

Solve the equation 5x^2 - 2x - 9 = 0 using the quadratic formula. WILL MARK BRAINLIEST.

Answers

Answer:

[tex] x = \dfrac{1}{5} \pm \dfrac{\sqrt{46}}{5} [/tex]

Step-by-step explanation:

5x^2 - 2x - 9 = 0

a = 5; b = -2; c = -9

[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]

[tex] x = \dfrac{-(-2) \pm \sqrt{(-2)^2 - 4(5)(-9)}}{2(5)} [/tex]

[tex] x = \dfrac{2 \pm \sqrt{4 + 180}}{10} [/tex]

[tex] x = \dfrac{2 \pm \sqrt{184}}{10} [/tex]

[tex] x = \dfrac{2 \pm \sqrt{4 \times 46}}{10} [/tex]

[tex] x = \dfrac{2 \pm 2\sqrt{46}}{10} [/tex]

[tex] x = \dfrac{1 \pm \sqrt{46}}{5} [/tex]

A softball pitcher throws a softball to a catcher behind home plate. The softball is 3 feet above the ground when it leaves the pitcher's hand at a velocity of 50 feet per second. If the softbal's acceleration is - 16
Ft/s2. This can be modeled with the equation (h=height, t=time) h(t)=16t^2 +50t+ 3
What is the time at which the softball would hit the ground it it were not hit or caught?

A.) .5 seconds
B.)3.12 seconds
c.) 3.18 seconds
D. ) 2.42

Answers

Answer:

Using their equation and the fact that the ball will fall 3 ft before reaching the ground:

3 = 16 t^2 + 50 t + 3 represents the given situation

16 t^2 + 50 t = t (16 t + 50) = 0

16 t + 50 = 0

t = 50 / 16 = 3.12 sec

Help please. It’s geometry and it asks to find the shaded region.

Answers

Answer: (a)

Step-by-step explanation:

Given

The diameter of the inner circle is [tex]d=14\ m[/tex]

thickness of the strip is [tex]t=2\ m[/tex]

So, the radius of inner circle is [tex]r=7\ m[/tex]

Radius of the outer circle [tex]R=7+2=9\ m[/tex]

Area of the shaded region is the difference of the area of outer circle and inner circle.

[tex]\Rightarrow \pi R^2-\pi r^2\\\Rightarrow \pi (9^2-7^2)\\\Rightarrow 3.142\times 32\\\Rightarrow 100.5\ m^2[/tex]

hence, option (a) is correct.
