•GIVEN : - 9a - 16 + 3 = 4 a
•Solve for a
•Show your work and check your work
Answer:
-1
Step-by-step explanation:
-9a(-16+3)=4a ; solve for whole numbers first.
-9a-(13)=4a ; A negative 16 plus a positive 3 is 13.
-9a-4a=13 ; Switch 13 and 4a to make it easier to solve.
-13a=13 ; Now divide each side by -13.
a=-1
Find the equation of the linear function represented by the table below in slope-intercept form.
Answer:
x=y
Step-by-step explanation:
What does ∆y represent?
Answer:
∆ stands for \vartriangle a example of this is A ∆ B (or A ⊖ B) means the set of elements in exactly one of A or B. or {1,5,6,8} ∆ {2,5,8} = {1,2,6} thats all I have for you sorry if this doesn't help
Step-by-step explanation:
Write the equation of the line in slope-intercept form that has: slope: -1 point: (2, -3) *
Answer:
y = -1x - 3
Step-by-step explanation:
y = mx + b
m = slope = -1
b = y-intercept = -3
Plug in
y = -1x - 3
Answer:
y = -x - 1
Step-by-step explanation:
Slope - Intercept form is y = mx + b
m = slope
b = y-intercept
We already have the slope of -1. Substitute it into the equation.
y = -x + b
To find b, substitute the given point (2, -3) into the equation.
-3 = -2 + b
b = -1
Substitute the value of b into the equation and you are left with:
y = -x - 1
Determine the type of triangle is this ?
Answer:
None of the above.

Answer:
19.89
Step-by-step explanation:
20 times .85= 17
17 times 1.17= 19.89
Answer:
$19.89
Step-by-step explanation:
first coupon.
x/20=15/100
20×15=300
300/100=3
20-3=17
then tax
x/17=17/100
17×17=289
289/100=2.89
2.89+17=19.89

A truck is carrying 102 bushels of onions, 101 bushels of peaches, and 103 bushels of corn. What is the total weight of the crops?
Answer:
306 is the answer for the question
The total weight of the crops is 304 bushels.
What is addition?Addition is the process of adding two or more numbers together to get their sum. Addition in math is a primary arithmetic operation, used for calculating the sum of two or more numbers.
Now it is given that,
Weight of onions = 102 bushels
Weight of peaches = 101 bushels
Weight of corn = 103 bushels
Total weight of crops = Weight of onions + Weight of peaches + Weight of corn
⇒ Total weight of crops = 102 bushels + 101 bushels + 103 bushels
⇒ Total weight of crops = 304 bushels
Thus, he total weight of the crops is 304 bushels.

The student council receives 35% of the sales from the tickets to a school dance. If they received $196.00, what was the total of the ticket sales? i need help!
Answer:
$560
Step-by-step explanation:
The student council receives 35% of the sales from the tickets to a school dance.
Let us represent the total of the ticket sales as x
35% of x = $196.00
35/100 × x = $196
35x/100 = $196
Cross Multiply
35x = $196 × 100
x = 196 × 100/35
x = $560
The total of the ticket sales is 560

1)A triangle has sides that measure 3 cm, 8 cm, and 4 cm. Do these measurements form a right
triangle?
A. Yes
B. No
Answer:
A. Yes
Step-by-step explanation:
the 8cm will be the hypotenuse and the 4cm and 3cm will join to create a right triangle.
Answer:
by using Pythagoras theorem,
a^2 + b^2 = c^2
LHS
3^2 +4^2
9 + 16 = 25
RHS
8^2 = 64
As both the sides of theoram aren't equal so the triangle with these measeures cant form a right angled triangle

Pedro is a salesman for a department store. He earns a commission of 8.5% on his sales. If he sold $1,200 in merchandise, what would his total commission be?
Answer: $102
Step-by-step explanation:
From the question, we are informed that Pedro earns a commission of 8.5% on his sales and that he sold $1,200 in merchandise.
Therefore, his total commission will be:
= 8.5% × $1200
= 8.5/100 × $1200
= 0.085 × $1200

A busy candy store is going to replace their current gumball machine
with a giant gumball machine. The globe on their current gumball
machine is 22" in diameter and its volume is 5,575 cubic inches.
Compared to what has been ordered, the current gumball machine's
volume is 532 cubic inches less than one-fourth the volume of the
globe of the giant gumball machine.
Use the information given to explore some of the mathematical concepts you have practiced so
far by answering the questions below. The formula for the volume of a sphere is .
1. Rewrite the formula for the volume of a sphere so that it is solved for r. Show all your work.

1.) V=4/3pi r^3
3V= 4pi r^3
3V/4pi = r^3

Answer: r = 3√3V/4pi
2.) Answer: 1/4V - 532 = 4/3pi 22^3
The sphere is a three-dimensional figure where the volume is given as
= 4/3 x πr³
4/3 x πr³ = 5575
The radius of the current gumball is ∛(117075/88) inches
5575 = (1/4)V - 532
The volume of the giant gumball is 24428 cubic inches.
What is a sphere?It is a three-dimensional figure where the volume is given as
= 4/3 x πr³
We have,
Current gumball machine.
Diameter = 22 inches
Radius = 22/2 = 11 inches
Volume = 5,575 cubic inches
The volume can be written as,
4/3 x πr³ = 5575
4/3 x 22/7 x r³ = 5575
r³ = (5575 x 3 x 7) / (4 x 22)
r = ∛(117075/88) inches
Giant gumball machine.
Volume = V
5575 = (1/4)V - 532
(5575 + 532) x 4 = V
V = 24428 cubic inches.
Thus,
The radius of the current gumball is ∛(117075/88) inches
The volume of the giant gumball is 24428 cubic inches.
