John needs to write 2,146 online math questions in 45 weeks. John is estimating how many questions he should write each week to meet the deadline. Which compatible numbers provide a better estimate for the number of question he should write each week, 2,000 ÷ 50 or 2,000 ÷ 40? Why?
Answer: 2,000 ÷ 50
Step-by-step explanation:
From the question, we are informed that John needs to write 2,146 online math questions in 45 weeks and that he is estimating how many questions he should write each week to meet the deadline.
The compatible numbers that provide a better estimate for the number of question he should write each week, is 2,000 ÷ 50. This is because rounding up of 2146 to the nearest thousand gives 2000. The number beside the thousand place is 2 and sinces it's not up to 5, the number becomes 2000. Likewise 45 to the nearest ten gives 50 since the number beside the ten is 5, therefore 1 will be added to 4 which becomes 5 and the number in the unit place is changed to 0, this makes the number become 50.
Therefore, the answer is 2000 ÷ 50.

Given the following diagram where BLUE is a rectangle, find the measure in degrees of
22 is 44% of what number? Will mark brainliest! <3
Answer:
44% of 50 is 22.
This is the case because 50 * 0.44 is 22.
Let me know if you have any other questions :)
Answer:
50
Step-by-step explanation:
44% = 44/100
44/100 × X = 22
X = 22 × 100/44
X = 100/2
X= 50
hence, 44% of 50 is 22

Shawn is a member of a book club. He pays a $50 yearly membership fee and can purchase books through the club for $5 each. His total annual cost is a function of the number of books, b, that he purchases in a year:
C(b) = 5b + 50
What is the total cost if he purchase 17 books in a year?
Answer:
The annual total cost is $135 when he purchases 17 books
Step-by-step explanation:
Given function is:
C(b) = 5b + 50
Here c is the output which is cost and b is the input which is number of books purchased in an year.
In order to find the total cost when he purchases 17 books, we have to put 17 in place of b and find the cost.
So,
Putting b = 17
[tex]C(17) = 5(17) + 50\\= 85+50 = 135[/tex]
Hence,
The annual total cost is $135 when he purchases 17 books
1. Suppose Alice eats 3 ounces of base 2 cake (doubles her height for each ounce eaten) at each meal. a) What will her height be multiplied by after two meals? b) After three meals? c) After four meals? d) After M meals?
Answer:
a)64
b)512
c)2^12
d)2^3m
Step-by-step explanation:
At every meal, 3 ounces of the cake is eaten
a) After 2 meals, the number of ounces consumed is 6 ounces
For each ounce, height is doubled , for 6 ounces, we have 2 * 2 * 2 * 2 * 2 * 2
Her height is multiplied by 64
b) After three meals
Total consumption is 3 * 3 = 9 ounces
So her height will be multiplied by 2^9 = 512
c) After four meals
Total ounces is 4 * 3 = 12
So her height will be multiplied by 2^12
d) After M meals
Number of ounces is m * 3 = 3m ounces
Her height will be multiplied by 2^3m
(Help needed ASAP I’m confused ) Solve the equation by using the distributive property first
Answer:
x=0
Step-by-step explanation:
simplify: 15(x-3) over 15 ( srry i dont know how to make that a fraction.)
3(2x-3)= 3x-9
3x-9=6x-9
move all terms containing x to the left side of the equation
-3x-9=-9
move all terms not containing x to the right side of the equation
-3x=0
divide both sides by -3 and simplify if needed
x=0

Jacob started a savings account with a 1% annual simple interest rate. His principal deposit was $147. He saved the money for 6 years. How much interest did he earn after 6 years?
Answer:
The interest Jacob earns after 6 years is $8.82
Step-by-step explanation:
The given parameters are;
The simple interest rate of the savings account, R = 1%
The principal deposit to the savings account, P = $147
The time duration Jacob saved the money, T = 6 years
The formula for simple interest, I, is given as follows;
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
Substituting the known values gives;
[tex]I = \dfrac{147 \times 1 \times 6}{100} = 8.82[/tex]
The interest Jacob earns after 6 years = $8.82.

Beth is putting up a fence in her yard so her dog can play outside. She purchased 80 feet of fencing. If the fenced area is a rectangle with a width of 30 feet, what is the length of the fenced area?
Answer:
10 feet
Step-by-step explanation:
The formula for the Perimeter fo a rectangle
= P = 2L + 2W
Where:
L = Length
W = Width
From the question
P = 80 feet
W = 30 feet
Hence:
80 = 2L + 2(30)
80 - 2(30) = 2L
80 - 60 = 2L
20 = 2L
L = 20/2
L = 10 feet
Hence, the length of the fenced area = 10 feet

Juan dispone de $ 500.000 y tiene las siguientes alternativas para invertir su dinero durante un año, estas son: Depósito en el "Banco Nacional" a una tasa de interés de 6,25% anual, sin capitalización de intereses en el año. Depósito en el "Banco Independiente" a una tasa de interés de 6,1% Nominal Anual, con capitalizaciones de intereses mensual. Depósito en el "Banco Fast" a una tasa de interés de 5,06% Nominal Anual, con capitalización de intereses trimestral. Depósito en el "Banco RAT" a una tasa de interés de 6,5% Nominal Anual, con capitalización de intereses bimestral. Determina el interés generado en el "Banco Nacional". $31.000 $31.250 $312.500 $531.250
Answer:
I = $31,250
Step-by-step explanation:
Para resolver este problema debemos de hacer uso de la ecuación de interés compuesto (en este caso en particular, también se podría utilizar la ecuación de interés simple, ya que solo se está capitalizando el interés durante un período)
[tex]FV=PV(1+\frac{r}{n})^{nt}[/tex]
En donde:
FV = Valor futuro
PV = Valor presente
r = tasa de interés
n = número de períodos de capitalización de intereses por año
t = número de años.
En este caso queremos conocer el valor futuro y conocermos el resto de variables:
PV=$500,000
r=0.0625
n=1
t=1
por lo que la fórmula se verá de la siguiente manera al sustituir los valores:
[tex]FV=500,000(1+\frac{0.0625}{1})^{(1)(1)}[/tex]
Al resolver la función obtenemos un valor de:
FV=$531,250
Como lo que nos interesa es conocer el interés, entonces le restamos el valor presente al valor futuro y obtenemos:
I=FV-PV=$531,250-$500,000
I=$31,250
La cual es nuestra respuesta.

Because of PEMDAS, Simplify 15x72 first. That will bring you to 1080. After that we add 6 to the 1080 because you always do Multiplication first. Your answer would be 1086 if you followed PEMDAS correctly.
PEMDAS:
1. Parentheses
2. Exponents
3. Multiplication
4. Division
5. Addition
6. Subtraction
That's the order of operations if you ever want to know what to do first.

19) If you choose from the following M 8 M colors, what is the probability that you choose blue? 5 green 6 yellow 8 blue 7 brown
7/26
3/26
8/26
1/26
What’s the answer
Answer:
The answer is C, or the third one (8/26).
Step-by-step explanation:
You add up all the objects (5+6+8+7) and get a total of 26 objects. Now you go to the amount of blue ones, and it's 8. So your probability of getting a blue one is 8 out of 26, since there's 8 blue ones out of the total 26. You can write this as 8/26, which is the answer.

#Team Rainbows
In order to evaluate energy demand for heating services, the number of heating degree days are calculated. The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day. If the high temperature for a day was 52°F and the low temperature for the same day was 45°F, what is the number of heating degree days?
Answer:
The number of heating degree days is 16.5.
Step-by-step explanation:
First, we calculate the average of the high ([tex]T_{H}[/tex]) and low temperatures of the day ([tex]T_{L}[/tex]), measured in degrees Fahrenheit. If we know that [tex]T_{H} = 52\,^{\circ}F[/tex] and [tex]T_{L} = 45\,^{\circ}F[/tex], then the average temperature ([tex]T[/tex]), measured in degrees Fahrenheit, is:
[tex]T = \frac{T_{L}+T_{H}}{2}[/tex] (1)
[tex]T = \frac{45\,^{\circ}F+52\,^{\circ}F}{2}[/tex]
[tex]T = 48.5\,^{\circ}F[/tex]
And the number of heating days is:
[tex]H = 65-48.5[/tex]
[tex]H = 16.5[/tex]
The number of heating degree days is 16.5.

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Let the equation of line be represented as A
The values of x = { -2 , -1 , 0 , 1 , 2 }
The value of y = { 8 , 2 , -4 , -10 , -16 }

1/2
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the matrix is not given.
The general form of a matrix is:
[tex]b[m*n] =\left[\begin{array}{ccc}b_{11}&b_{12}&b_{13}........b{1n}}\\b_{21}&b_{22}&b_{23}........b{2n}\\b_{31}&b_{32}&b_{33}........b{3n}\\ \\ \\b_{m1}&b_{m2}&b_{m3}........b{mn}\end{array}\right][/tex]
Where m and n represent the [tex]number\ of\ rows\ and\ columns[/tex] respectively.
Notice the position of b11
This means that b11 is at the first column and first row.
Take for instance matrix b is:
[tex]b = \left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right][/tex]
The element at the first row and first column is 1.
Hence
[tex]b_{11} = 1[/tex]
