Answer:
[tex]x + 4[/tex]
Step-by-step explanation:
The question have missing details.
Because, the question says she collected some cans "after picnic"; This means that she has some cans "before picnic"
So, we assume that she has x bags of can before the picnic.
[tex]After\ Picnic = 4[/tex]
So, the total number of bags collected is:
[tex]Total = Before + After\ Picnic[/tex]
[tex]Total = x + 4[/tex]
If x is 5, then she took 9 bags of can to the recycling center
If x is 2, then she took 6 bags of can to the recycling center
If x is 0, then she took 4 bags of can to the recycling center

Colton sold a total of 28 tee shirts and sweatshirts as a fundraiser for his football team. If tee shirts cost 12 dollars each and sweatshirts cost 20 dollars each and he raised a total of 424 dollars how many tee shirts did he sell?
Answer:
11 sweatshirts and 17 t shirts
Step-by-step explanation:
[tex]t + s = 28\\12t = 20s = 424[/tex]
Step one: cancel out one variable. In this one, t.
[tex]-12(t + s = 28)\\-12t -12s =-336[/tex]
Now that we have that, subtract that from the other expression.
[tex]12t + 20s = 424\\-12t -12s = 336[/tex]
You should get:
[tex]8s = 88\\ s = 11[/tex]
Plug s in any expression
[tex]t + 11 = 28[/tex]
You should know where to go from there, I'm lazy :p
Then t = 17
GOod Luck!!!!
13 added to the product of an integer and negative 7 is 62
Answer:
Step-by-step explanation:
[tex](x*-7)+13 = 62[/tex]
[tex](x*-7) = 62 - 13[/tex]
[tex]x*-7 = 49[/tex]
[tex]x = 49 / -7[/tex]
[tex]x = -7[/tex]
check work
[tex]((-7)*-7)+13 = 62[/tex]
[tex](49)+13 = 62[/tex]
[tex]62 = 62[/tex]
¿Cuántas cifras tiene el número quinientos cincuenta y cinco mil? Respuesta: ____________ CM DM UM C D U NÚM. DE CIFRAS
Answer:
6 cifras.
Step-by-step explanation:
Siempre que tengamos un numero que termina en "mil", entonces la primer parte la escribimos y luego ira una coma:
por ejemplo, en "ciento once mil trecientos catorce"
lo separamos en:
"ciento once mil" y "trecientos catorce"
y lo escribimos como:
"ciento once" , "trecientos catorce"
111,314
Ahora que definimos esto, vamos a nuestro problema.
Tenemos el numero "quinientos cincuenta y cinco mil"
El cual podemos escribir como:
555,000
Ahora simplemente podemos contar las cifras, tenemos 6.
las cuales son:
Cientos de miles = CM = 5
Decenas de miles = DM = 5
Un miles = UM = 5
Cientos = C = 0
Decenas = D = 0
Unidades = U = 0

In 1990, the rate of change of the world population was approximately 0.09125 billion per year (or approximately 1 million people every four days). The world population was estimated to be 5.3 billion in 1990. Use the linear model to predict the world population in 2025. a. According to the model, in 2025 the world population will be 84,937,500,000 b. According to the model, in 2025 the world population will be 8,493,750,000 c. According to the model, in 2025 the world population will be 5,302,607,000 d. According to the model, in 2025 the world population will be 8,037,500,000
Answer:
According to the model, in 2025 the world population will be 8,493,750,000
Step-by-step explanation:
Rate at which population was growing per year = 0.09125 billion
Initial population figure in 1990 = 5.3 billion
World population prediction in 2010 ;
Predicted population figure :
Initial population + (population growth value per year * number of years)
number of years = (2025 - 1990) = 35 years
Predicted population figure in 2025 :
5.3 + (0.09125 * 35)
5.3 + 3.19375
= 8.49375 billion.

Colin is training for a triathlon and needs to swim a certain distance for today's workout. If he swims at the rec center pool, he will complete a 264-yard warmup and then swim laps in a lane that is 34 yards long. If Colin swims at the indoor pool at his gym, he will complete a 120-yard warmup, plus a main set that consists of 35 yards per lap. If Colin swims the correct number of laps, he can complete the same distance in either pool. How long will Colin's workout be in total? How many laps will that take?

Find the measure of angle A If Angle A = 2x+18 and angle C = 3x+12
Answer:
Below in bold.
Step-by-step explanation:
2x + 18 + 3x + 12 = 180 (property of a cyclic quadrilateral).
5x = 180 - 18 -12
5x = 150
x = 30
So m < A = 2(30)+18
= 78 degrees.
Solve the system using elimination show all work for full credit.
X + 3y = -14
4x - 3y = 2
Help me
x = −12/5 and y = −58/15
Step-by-step explanation:
x+3y=−14
4x−3y=2
Add these equations to eliminate y:
5x = −12
Then solve 5x = −12 for x:
5x = −12
5x/5 = −12/5 (Divide both sides by 5)
x = −12/5
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
x + 3y = −14
Substitute −12/5 for x in x + 3y = −14:
−12/5 + 3y = −14
3y + −12/5 = −14
(Simplify both sides of the equation)
3y + −12/5 + 12/5 = −14 + 12/5
(Add 12/5 to both sides)
3y = −58/5
3y/3 = −58/5/3
(Divide both sides by 3)
y = −58/15

Please use the following scenario for this question and the following 4 questions. The national academy of sciences reported in a 1997 study that 40% of research in mathematics is published by US authors. The math chairperson of a university wishes to test the claim that this percentage is no longer 40%. He has no indication of whether the percentage has increased or decreased since that time. He surveys a simple random sample of 130 recent articles published by reputable math research journals and finds that 62 of these articles have US authors. Does this evidence support the math chairperson's claim that the percentage is no longer 40%
Answer:
The evidence does not support the math chairperson's claim that the percentage is no longer 40%
Step-by-step explanation:
The known population percentage of research in mathematics published by US authors = 40%
The proportion, p = 0.40
Therefore, q = 1 - p = 1 - 0.4 = 0.6
The number of articles in the sample = 130
The number of articles by US authors in the sample = 62
Therefore, the proportion of US authors in the sample, [tex]\hat p[/tex] = (62/130) × 100 =
[tex]0.4\overline{769230}[/tex]
∴ The percentage of US authors in the sample ≈ 47.7%
The null hypothesis, H₀; p = 0.4
The alternative hypothesis, Hₐ; p ≠ 0.4
The z-test is given as follows;
[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p\cdot q}{n}}}[/tex]
[tex]z=\dfrac{0.477-0.40}{\sqrt{\dfrac{0.4\times 0.6}{130}}} \approx 1.792[/tex]
The p-value P(Z > 1.79) = 2 × (1 - 0.96327) = 0.07346
Therefore, given that the p-value is larger than 0.05 there is significant evidence in favor of the null hypothesis and we reject the alternative hypothesis
Therefore, also, there is not enough statistical evidence to support the math chairperson's claim that the percentage is no longer 40%.
Eight people go to a movie. Adult tickets cost $15 and children's tickets cost $8
The total cost was $85. Write an equation and use it to help you find the numbers of
adults and children who went to the movie.
Answer: number of adults = 3, number of children = 5
Step-by-step explanation:
let the number of adults be x, and the number of children be y.
x + y = 8 , 15x + 8y = 85
1st equation x 8 = 8x + 8y = 64
[tex]8x+8y-15x-8y = 64 - 85\\-7x = -21\\x=3[/tex]
substitute x=3
[tex]3+y=8\\y=5[/tex]

Factor the following polynomial 14x^2 - 35x
Answer:
The binomial 14[tex]x^{2}[/tex] - 35x can be factored as 7x(2x+5)
Step-by-step explanation:
When factoring, you want to factor each constant or variable by their greatest common factor (or GCF). Since [tex]14x^{2}[/tex] and [tex]35x[/tex] has a greatest common factor of 7x, factor each term by 7x and you'll get [tex]7x(2x+5)[/tex].
