pls help me besties
Answer:
b=40 I just took this quiz
Answer:b=40 a=100
Step-by-step explanato a line is 180 degrees, the outside of the triangle is 140 degrees so the inside must be 40 to make 180 and a is also 40 because the triangles sides are the same
to find a we now know that both angles on the bottom 40+40 will add up to 80 and to make a complete triangle we need 180 so the measure of a is 100 degrees
a=100
b=40

B. 8 cm
C. 12 cm
D. 16 cm
Answer:
B. 8cm
Step-by-step explanation:
radius = 4cm
volume = 4/3 π r³

The path of a diver diving off a 10-foot platform can be represented by the function h(x) = - 0.5(x^2 - 4x - 21) where h is the diver's height above water and x is the horizontal distance from the platform (in feet).
What does the positive zero represent?
Answer:
x = -3 and 7
Step-by-step explanation:
Given the path of a diver expressed as;
h(x) = - 0.5(x^2 - 4x - 21)
The positive zero occur at when h(x) = 0
Substitue
0 = - 0.5(x^2 - 4x - 21)
-0.5x^2 + 2x + 10.5 = 0
Multiply through by -10
5x^2 - 20x - 105 = 0
x^2 - 4x - 21 = 0
x^2 - 7x+3x - 21 = 0
x(x-7)+3(x-7) = 0
(x+3)(x-7) = 0
x = -3 and 7
Hence the positive zero displacement occurs at x = -3 and 7

Calculate the slope of the line passing through the points (-1, -5) and (-9, -1)
a) undefined
b) 0
c) -0.5
d) -2
Answer:
C
Step-by-step explanation:
(y2-y1)/(x2-x1) = slope
y2-y1 = (-1)-(-5) = 4
x2-x1 = (-9)-(-1) = -8
slope = 4/(-8) = -0.5

Step-by-step explanation:
Move all terms containing x to the left side of the equation.
x−4=−10
Move all terms not containing x to the right side of the equation.
Add 4 to both sides of the equation.
x=−10+4
Add −10 and 4
X=-6
what is the answer for y=__x+__
Answer:
y=1/-4x+4
Step-by-step explanation:
hey
Step-by-step explanation:
Slope (x) is rise/run. From one intersecting point to the next, we find it is moving 4 y down and 1 x over. Using this we conclude the slope is -4/1x (or -4x)
The second number in the system is b, or y-intercept. The line intercepts at 4y. If we combine these together, the outcome is y = -4x + 4

Find the area and perimeter of the shaded region. Stuck on this one can someone help me
Answer:
perimeter-
perimeter outer rectangle = 2 (l+b)
=2×8+9
= 2×17
2×17 =34 cm sq.
perimeter of inner rectangle = 2 (l+b)
= 2×5+3
=2× 8
= 16 cm sq.
perimeter of shaded portion= 34 - 16
= 18 cm sq.
area-
area of inner rectangle =l×b
l×b = 3×5
3×5=15
15 cm sq.
area of outer rectangle =l×b
l×b= 9×8
9×8= 72
72 cm sq.
area of shaded portion = 72 -15 =57 cm sq.
hey there! In second method i have done first area of inner rectangle but you have to do first area of outer rectangle...
hope it helps you....
Answer:
Let A1 = be the large rectangle and A2 the small rectangle
=> Area A1: S1 = a1.b1 => S1 = 8 x 9 = 72m2
=> Area A2: S2 = a2.b2 => S2 = 3 x 5 = 15 m2
=> Area of the remaining surrounding square: S1-S2 = 72-15 = 67m2
=> Perimeter A1: P1 = 2 (a1 + b1) = 2 (9 + 8) = 34m
=> Perimeter A2: P2 = 2 (a2 + b2) = 2 (3 + 5) = 16m
=> Perimeter of the surrounding square: P1-P2 = 34-16 = 18m

What is the volume of the following rectangular prism
Answer:
8 1/8 or 8.125
Step-by-step explanation:
To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.
since we only have length and width we just multiply that
16 1/4 x 1/2 = 8 1/8 or 8.125
so the volume is 8 1/8 0r 8.125

A jar is filled with pennies, nickels, and dimes. The probability of picking a penny is 1/4, and the probability of picking a dime is 1/3. What is the probability of picking a nickel? Write your answer as a decimal rounded to the hundredths place.
Answer:
What Are The Options?
Step-by-step explanation:
Answer:
0.42
Step-by-step explanation:
given:
P (penny) = 1/4
P (dime) = 1/3
since the only other possibility is to pick a nickel, hence
P (nickel)
= 1 - 1/4 - 1/3
= 5/12
= 0.4166667
= 0.42 (nearest hundredth)

In a survey of 800 people, 32% preferred cats and 27% preferred dogs. How many more people preferred cats than preferred dogs?
Calculate the amount of people on both sides.
32% preferred cats
32% of 800
0.32 × 800 = 256 people
27% preferred dogs
27% of 800
0.27 × 800 = 216 people
So 256 people preferred cats and 216 people preferred dogs.
256 - 216 = 40 people
40 more people preferred cats than preferred dogs
40 people preferred cats more than preferred dog.
What is percentage?Percentage is a measurement to find value of given number out of hundred.
Given that,
Total number of people participated in survey = 800.
Percentage of people who preferred cats = 32%,
And percentage of people who preferred dogs = 27%.
The percentage of people who preferred cats more than preferred dogs
= 32 - 27
= 5 %
The number of people preferred cats more than preferred dogs
= 800 x 5/100
= 40.
There are 40 more people preferred cats than dog.
