3.) There are 3 brothers. The first brother is twice as old as the second. The second is twice as old as the third.
If the sum of their ages is 28, how old is each brother?
Answer:
The first brother is 16, the second brother is 8 and the third brother is 4.
Step-by-step explanation:
Since the sum of all the brothers is 28, that means the cap of how old the oldest can be is 28. I just stated with numbers less then 28 that were dividable by two which means all the numbers had to be. So 16 for the first, 8 for the second and 4 for the youngest is the right answer I hop.
Oscar made 28 out of 35 field goals during football practice. Which proportion shows how to find the percent of field goals made?
Answer:
80 %
Step-by-step explanation:
Step one:
Given data
We are told that Oscar made 28 out of 35 field goals during football practice.
Required
The percentage accuracy
Step two:
% Accurracy= number of goals/number of practice*100
% Accurracy= 28/35*100
% Accurracy=0.8*100
% Accurracy= 80%
Hence the percentage that he made is 80 %

Choose the inequality that matches the verbal description.
Anna has at least 8 dollars.
A) x ≤ 8
B) x ≥ 8
C) x > 8
D) x < 8
Group of answer choices
A
B
C
D
Answer:
B
Step-by-step explanation:
At least has to be the number or more.
So it could be 8, 9, 10... basically any number that's 8 or more.
Answer:
B) x ≥ 8
Step-by-step explanation:
x represents the number of dollars that Anna has.
If Anna has at least 8 dollars, she could have 8 or any number greater than 8 dollars. Anna could have 8, 9, 10, 11... etc. dollars.
This means that x is equal to or greater than 8.
x ≥ 8

the sum of a number times 4 and 29 is at least 26
Answer:
4 + 29 ≥ 26.
Step-by-step explanation:
I'm assuming you want me to make an inequality with this, so I will do that. Since sum means to add, we write this: 4 + 29. At least can translate to greater than or equal to, we can write that symbol as ≥. Now, let's write the whole inequality, we can write it as 4 + 29 ≥ 26.
Explain how to tell if two terms are alike. Show one pair of like terms that each contain at least two variables. Show how to add these like terms. Then show a second pair of terms that are NOT alike, but share some of the same variables. Explain why they are not alike.
Answer:
Two mathematical terms are alike (not alike) , if they have same (different) variables & in same (different) mathematical treatment.
Step-by-step explanation:
Two mathematical terms are alike, if they have same variables & in same mathematical treatment.
Eg : 2 xy , 5 xy. These are alike, as they have product of x & y being multiplied with constants.
They can be added, subtracted by adding or subtracting their constants.
2 xy + 5 xy = (2 + 5) xy = 7 xy
5 xy - 2 xy = ( 5- 2 ) xy = 3 xy
Two mathematical terms that are not alike are : 2 xy & 5xz , as former has variables x & y, latter has variables x & zPLS HELP ME NWWWWWWWWWWWWW

Which statements are true?
Select each correct answer.
Since −6 is 6 units to the left of 0, |−6|=6 .
The absolute value of −6 is negative.
The absolute value of −6 is less than the absolute value of 6.
−6 is closer to zero on the number line than −7 , so |−6|<|−7| .
Answer:
The first one and the last one are true (Since −6 is 6 units to the left of 0, |−6|=6 and −6 is closer to zero on the number line than −7, so |−6|<|−7|.)
Step-by-step explanation:
Absolute value is the distance to zero, and it is always positive. That means the positive and negative versions of a number have the same absolute value. That means the first one is true, and the second and third ones are false. For the last one, -6 is closer to zero, so that means it would be true (The absolute value of -6 is 6, and the absolute value of -7 is 7).

Brandi sells insurance plans that cost $1,500 each. She makes a 7.5% commission on each plan that she sells. Her goal is to make $3,600 in commission fees this month.
Please quickly
How many insurance plans must Brandi sell to meet her goal? Show how you found your answer.
Answer:
Thw answer is 32
Step-by-step explanation:
Answer:
She should sell 32 plans.
Step-by-step explanation:
If she earns 7.5% of $1,500 on each plan she sells, that mean she makes $112.50 on each plan sold. Divide $3,600 by that and you get how many plans she should sell to make $3,600 this month. (3600 / 112.5 = 32)
For problems a - d, write the function in the form LaTeX: y=ab^x. y = a b x . a) LaTeX: y=3\sqrt{4^{2x}} y = 3 4 2 x b) LaTeX: y=\frac{\sqrt[3]{5^{3x}}}{2} y = 5 3 x 3 2 c) LaTeX: y=8^{x+2} y = 8 x + 2 d) LaTeX: y=\frac{3^{2x+1}}{\sqrt{3^{2x}}}
Step-by-step explanation:
To write the equation in LaTeX in form y = ab^x or [tex]ab^x[/tex] for y = abx .........(1)
(a) LaTeX: y=3\sqrt{4^{2x}} y = 3 4 2 x can be written in mathematical form as
[tex]y=3\sqrt{4^{2x}}[/tex] ; y = 342x
on comparing with equation (1) we get a =3 and b =4
⇒y = 34^x or [tex]34^x[/tex]
(b) LaTeX: y=\frac{\sqrt[3]{5^{3x}}}{2} y = 5 3 x 3 2 can be written in mathematical form as
[tex]y=\frac{\sqrt[3]{5^{3x}}}{2}[/tex] ; y = 342x
on comparing with equation (1) we get a =0.5 and b =5
⇒y = [tex]\frac{1}{2}5^x[/tex]
(c)LaTeX: y=8^{x+2} y = 8 x + 2 can be written in mathematical form as
[tex]y=8^{x+2}[/tex]
on comparing with equation (1) we get a =64 and b =8
y = [tex]64 . 8^x[/tex]
(d)LaTeX: y=\frac{3^{2x+1}}{\sqrt{3^{2x}}} can be written in mathematical form as
[tex]y=\frac{3^{2x+1}}{\sqrt{3^{2x}}}[/tex] = [tex]3^{x+1}[/tex] = [tex]3 . 3^x[/tex]
on comparing with equation (1) we get a =3 and b =3
y = [tex]3 . 3^x[/tex]

What is a ratio?
The quantitative and relatable relation between two amounts of goods or numbers shows the number of times one value contains or is contained within the other or one number/value with respect to the other number/value.
It is basically the relationship between two similar magnitudes with respect to the number of times the first contains the second.

x: y x / yExample: the ratio of 1 to 2, written 1:2 or 1/2.

A restaurant owner has found that 80% of her customers return to the restaurant within two weeks. She wants to create a tool that will simulate the habits of her customers and allow her to predict the probability that three of the next four customers to visit her restaurant will return within two weeks. Which spinner simulation uses an appropriate device and has the correct number of trials? a spinner divided into 5 congruent sectors, spun 3 times a spinner divided into 5 congruent sectors, spun 4 times a spinner divided into 2 congruent sectors, spun 3 times a spinner divided into 2 congruent sectors, spun 4 times
B. A spinner divided into 5 congruent sectors, spun 4 times
Have a good day
The correct answer is “a spinner divided into 5 congruent sectors, spun 4 times”
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
Given that, A restaurant owner has found that 80% of her customers return to the restaurant within two weeks. She wants to create a tool that will simulate the habits of her customers and allow her to predict the probability that three of the next four customers to visit her restaurant will return within two weeks.
The correct spinner to use among the 4 should have a probability of winning of 80%, similar to what the owner has found out. So, we must calculate the probability of each spinner.
1. Spun 3 times, and chance of winning is 1 in 5, therefore P = (3) (1/5) = 0.6 = 60%
2. Spun 4 times, and chance of winning is 1 in 5, therefore P = (4) (1/5) = 0.8 = 80%
3. Spun 3 times, and chance of winning is 1 in 2, therefore P = (3) (1/2) = 1.5 = 150%
4. Spun 4 times, and chance of winning is 1 in 2, therefore P = (4) (1/2) = 2 = 200%
We can see that there is only 1 choice that has 80% probability,
Hence, the correct answer is “a spinner divided into 5 congruent sectors, spun 4 times”
