Gloria enjoys playing Skee ball — an arcade game where players toss a ball so it rolls up a ramp and falls into one of several slots. Each slot is worth a different number of points based on how difficult it is to land the ball in that slot. Gloria only aims at the most difficult slot, which is worth 100100100 points, but she only has a 10\%10%10, percent chance of landing the ball in that slot. If she misses, her ball will certainly land in the 101010 point slot.

Hope it helps....... pls mark as brainliest
Answer:
The second: ∠Q, ∠R, ∠PStep-by-step explanation:
In every triangle the largest angle is oposite to the longest side and the smaller angle is oposite to the shortest side
the longest side is PR=15, so the largest angle is Q
the shortest side is QR=7, so the smallest angle is P

Answer:
The maximum height of the ball was 30 feet
The ball was in the air for 6 seconds
Step-by-step explanation:
The maximum height was 30 feet because that is the highest y-value before the y-values start decreasing. You could also call it the peak.
You would know the ball was in the air for 6 seconds because the time elapsed between it's liftoff at 0 feet and it's landing at the other 0 feet was 6 seconds.

2(5x+3) = 3x - 9 + ____
Answer:
3/7
Step-by-step explanation:
Let's solve your equation step-by-step.
2(5x+3)=3x+9
Step 1: Simplify both sides of the equation.
2(5x+3)=3x+9
(2)(5x)+(2)(3)=3x+9(Distribute)
10x+6=3x+9
Step 2: Subtract 3x from both sides.
10x+6−3x=3x+9−3x
7x+6=9
Step 3: Subtract 6 from both sides.
7x+6−6=9−6
7x=3

Of the 342 students in sixth grade, 178 are car riders. What percent of the
sixth grade students are car riders?
Answer:
164
Step-by-step explanation:
342-178=164 im not sure i understand it but i think thats the answer HOPE I HELPED
Answer:
About 52 percent are car riders.
Step-by-step explanation:
Using cross multiply, you should set up this: ?/100 178/342
Now you multiply 178 by 100 to get 17800
Next you divide 17800 by 342.
You get: 52.0467836257
Round to get 52.05 percent.

Step-by-step explanation:
Answer:
(4)
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - [tex]\frac{2}{3}[/tex] x - 5 ← is in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{2}{3} }[/tex] = [tex]\frac{3}{2}[/tex] → (4)
What is the volume of a hemisphere with a radius of 9.7 cm, rounded to the nearest tenth of a cubic centimeter? please i need help ill do a zoom call and i'll give you all my Branly points if uu help me.
Answer:
volume of hemisphere =1912.26cm^3
Step-by-step explanation:
radius(r)=9.7cm
now volume of hemisphere=(2/3)π[tex]r^{3}[/tex]
=(2/3)*(22/7)*(9.7)^3
=(2/3)*(22/7)*912.673
=(2/3)*2868.40086
=1912.26cm^3
The volume of a hemisphere is [tex]1910.52 cm^{3}[/tex].
What is volume of a hemisphere?
A hemisphere is half of a full sphere, we can calculate the volume of a hemisphere just by halving the volume of the complete sphere.
So, we can calculate the volume of a hemisphere by using the following formula,
[tex]$V=\frac{2}{3}\pi {{r}^{3}}$[/tex]
Here, [tex]r[/tex] is the radius, [tex]V[/tex] is the volume of hemisphere.
So,
It is given that the radius is [tex]9.7 cm[/tex].
We have to find [tex]V[/tex].
So,
[tex]$V=\frac{2}{3}\cdot 3.14\cdot {{\left( 9.7 \right)}^{3}}$[/tex]
[tex]V=1910.52[/tex]
Hence, the volume of hemisphere is [tex]$1910.52\text{ c}{{\text{m}}^{3}}$[/tex].

Answer:
Step-by-step explanation:
The triangle should equal 180 degrees. You already have 84+60= 144
Take that 144 with the equation of the other angle. 144-180 is 36
5x+1=36 subtract 1 from both sides
5x=35 divide by 5
x=7
check:
36 + 84+60= 180

Given, We can describe 15x-10 as an expression, We would describe 9x+5=32 as an:
A function is a collection of ordered pairs where each input (x-value) has a single relationship to each output (y-value). An equation need not always be a function. If an equation satisfies the criteria for a function, then it is a function. However, not all equations are functions.
A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation.

What is the final amount if 1885 is increased by 5% followed by a further 18% increase
9514 1404 393
Answer:
2335.515
Step-by-step explanation:
The first increase multiplies the original amount by 1 + 5% = 1.05.
The second increase multiplies the already increased amount by 1 + 18% = 1.18.
Then the final amount is ...
1885(1.05)(1.18) = 2335.515

During a typing test , bob typed 40 words in 2/3 of a minute what is bobs typing speed.
Work Shown:
40 words = (2/3) of a minute
3*40 words = 3*(2/3) of a minute ... multiply both sides by 3
120 words = 2 minutes
120/2 words = 2/2 minutes .... divide both sides by 2
60 words = 1 minute
Bob's speed is 60 words per minute (wpm)

Suppose there is a 1.1 drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 60.5, what will be the temperature when the plane reaches an altitude of 11,000?
Answer:
48.4° CStep-by-step explanation:
Step one:
We are told that there is 1.1° drop in temperature for each 1000 ft climb.
since the given altitude is 11,000ft,
hence there =(11000/1000)*1.1
= 11*1.1
=12.1°C drops in temperature.
Therefore, given that the temperature on the ground is 60.5° C
The temperature above is 60.5-12.1=48.4° C
The plane reaches an altitude of 11,000 is 48.4° C

Answer:
If solved by using quadratic formula, you would need to solve the rational equation by combining expressions and isolating the variable y .
y ≈ 2.45043159
Step-by-step explanation:
The expression (y⁴ - 81) / (y - 3) simplifies to (y + 3)(y² + 9) after factoring and canceling common terms.
expression (y⁴ - 81) / (y - 3)
by simplification
factoring the numerator
y⁴ - 81 = (y²)² - 9² = (y² - 9)(y² + 9)
factoring the denominator
y - 3
we get, (y² - 9)(y² + 9) / (y - 3)
simplifying
(y² - 9) = (y - 3)(y + 3)
(y - 3)(y + 3)(y² + 9) / (y - 3)
