Answer:
40 and 10
Step-by-step explanation:
if you add them you get 50 and if you subtract them you get 30
Answer:
40 and 10
Step-by-step explanation:
Let the bigger number = x
Let the smaller number = y
x+y=50
x-y=30
(add the equations)
(x+x)+(y-y)=(50+30)
2x=80
x=40
x+y=50
40+y=50
y=10

To get the answer you have to fill in the 14 for r because that is the radius. Then multiply 14 by it self to get 196 then multiply that by pie to get your answer of 615.75216.
So the answer is 615.75216
here's the question

Answer:
y = 350x
Step-by-step explanation:
To find the equation of the chart, we simply find the slope and then follow the slope-intercept equation.
Points on the chart: (0, 0) and (1.5, 525)
Slope:
m=(y2-y1)/(x2-x1)
m=(525-0)/(1.5-0)
m=525/1.5
m = 350
Slope-intercept:
y - y1 = m(x - x1)
y - 0 = 350(x - 0)
y - 0 = 350x
y = 350x
Solve each equation.
1.5(n - 4) = -60
2.-3t+-8 = 25
3.7p - 8 = -22
4. (+40) = -4
5.4(w + 1) = -6
Answer:
1. n= -8
2. t= -11
3. p= -2
4. Not quite sure thats a proper equation.
5. w= -2.5 if thats the actual equation. if youre missing a 0 on 6 then its -15
Solve each inequality. Then check each number that is a solution
I Don't know how to solve this. as nothing has helped so far.
Answer:
3, 6, 4, 5
Step-by-step explanation:
First of all we have to multiply 2 by 2x and -9 and we obtain
4x -18 ≤ 6
now we have to move -18 on the right side of the minor or equal and change its sign
4x ≤ 6 + 18
now we have to added up 6 and 18
4x ≤ 24
At least we have to divide the the two members by 4
x ≤ 6
We have to find the numbers ≤ 6
so the answer is : 3, 6, 4, 5
Answer:
click on 3,6,4,5 are less than or equal to 6
Step-by-step explanation:
2(2×3-9)= -6
2(2×6-9)= 6
2(2×4-9)= -2
2(2×5-9)= 2
2(2×7-9)= 10

If $18 is 45% what is 100%
Answer:
$40Step-by-step explanation:
45% = 45/100 = 0.45
0.45x = 18x = 18/0.45x = 40100% is $40
Answer:
solution given;
let total be X
45% of X=$18
X=$18×100/45=$40
So.100% is $40.
1- “Dados provenientes de 2.783 homens e 5.018 mulheres maiores de 65 anos de idade da Pesquisa Nacional de Saúde dos Estados Unidos de 1990 determinaram a prevalência de atividade física regular, que naquele estudo foi definida como a participação em atividades físicas no tempo livre por três ou mais vezes por semana e por mais de 30 minutos nas últimas duas semanas. Com esses parâmetros os autores encontraram uma prevalência de atividade física regular de 37% no sexo masculino e 24% no sexo feminino.” Quantos idosos do sexo masculino e do sexo feminino praticam atividade física regular?

Explanation:
The geometric mean can be represented by [tex] \sqrt[n]{x_{1} • x_{2} • x_{3} • .. x_{n}} [/tex].
Which is the mean of the product of n numbers, used to find the average of a geometric progression.
Don't get confused by geometric mean, it is only asking you about the next numbers in the geometric sequence given the first and sixth term.
The explicit rule for a geometric sequence can be modeled by:
[tex] a_{n} = a_{1} • r^{n-1} [/tex]
Where [tex] a_{n} [/tex] is the nth term, [tex] a_{1} [/tex] is the first term in the sequence, n is the term number, and r is the common ratio.
Since we already know the first term, [tex] a_{1} [/tex] will simply be 32.
Since we know it's geometric, there will be an exponential relationship, which means that we will use the geometric mean to find the common ratio.
There are 6 total terms, r is raised to the n – 1 so 6 – 1 = 5, and that will be the degree of this root.
[tex] \sqrt[5]{\frac{a_{6}}{a_{1}}} [/tex] =
[tex] \sqrt[5]{\frac{1}{32}} [/tex] =
[tex] \frac{1}{2} [/tex].
Therefore: [tex] r = \frac{1}{2} [/tex].
Using all the information we have, we can find the explicit rule:
[tex] a_{n} = a_{1} • r^{n-1} [/tex]
[tex] a_{1} [/tex] = 32[tex] r = \frac{1}{2} [/tex][tex] a_{n} = a_{1} • r^{n-1} [/tex] →
[tex] \boxed{a_{n} = 32 • (\frac{1}{2})^{n-1}}[/tex]
________________________________
We can test that this works by substituting the number location of the term you want to find.
For instance:
[tex] a_{1} = 32 • (\frac{1}{2})^{1-1} [/tex]
[tex] a_{1} = 32 • (\frac{1}{2})^{0} [/tex]
[tex] a_{1} = 32 • 1[/tex]
[tex] a_{1} = 32 [/tex]
[tex] a_{6} = 32 • (\frac{1}{2})^{6-1} [/tex]
[tex] a_{6} = 32 • (\frac{1}{2})^{5} [/tex]
[tex] a_{6} = 32 • \frac{1}{32} [/tex]
[tex] a_{6} = 1 [/tex]

Last year, Lien earned $1,600 more than her husband. Together they earned $51,000. How much did each of them earn?
Answer:
Lien: $26300 Her husband: $24700
Step-by-step explanation:
x+(x+1600)=51000
2x+1600=51000
2x=49400
x=24700
Her husband earned 24700
24700+1600=26300
Lien earned 26300

The circle graph shows how Tremaine divided his time on the computer last week.
Tremaine used the computer a total of 30 hours last week. How many more hours did Tremaine use the computer to play video games than to do research?
Group of answer choices
6 hours
20 hours
7.5 hours
1.5 hours
Please explain the answer to me
Answer: 6
Step-by-step explanation:
So he spends 25% of his 30 hours on games so 30x0.25=7.5 since 25% is equal to 0.25. He also spends 5% of the 30 hours on research. 30x0.05=1.5. 7.5-1.5=6

Find the x- and y-intercepts of the graph of x + 3y = 33. State your answers as
whole numbers or as improper fractions in simplest form.
Answer:
x intercept is (33,0)
y intercept is (0, 11)
Step-by-step explanation:
x-intercepts are found when y=0
x + 3(0)=33,,, x=33
y-intercepts are found when x=0
0 + 3y= 33,,, y=11
Is the point (-4, 1/2) on the graph of y= 1\2 x-4 ? How do you know? Show your work/thinking.
9514 1404 393
Answer:
no, when x is even, y will be an integer, not a fraction
Step-by-step explanation:
We observe that the coefficient of x is 1/2, so the x-term will be an integer only if x is a multiple of 2 (even). If the x-term is an integer, y will be an integer.
The given point has x even (-4), so we expect y to be an integer. The given point has y=1/2, not an integer, so the point will NOT be on the graph.
