In Joel's town, about 33 out of 100 cats are black. If Joel walks by 21 cats in 1 week, predict how many of those cats are black?
Answer:
7 cats are black
Step-by-step explanation:
Since 33 out of 100 cats are black then that means that 33% of the cats are black.
Since he walked by 21 cats 33% of them are most likely black.
So you do .33 x 21= 6.93 which can be rounded up to 7 cats

A new four way intersection is being constructed in New York Hyde park through point P(-3,-15) an equation of the line representing one road is y = -3/4x + 7 create an equation of the line representing the new road that will run perpendicular to the first road
Given:
A new four way intersection is being constructed in New York Hyde park through point P(-3,-15).
Equation of line of one road : [tex]y=-\dfrac{3}{4}x+7[/tex].
New road that will run perpendicular to the first road
To find:
The equation of line for the new road.
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept.
We have,
[tex]y=-\dfrac{3}{4}x+7[/tex]
Slope of this line is [tex]-\dfrac{3}{4}[/tex] and y-intercept is 7.
Product of slopes of two perpendicular line is -1.
[tex]m_1\times m_2=-1[/tex]
[tex]-\dfrac{3}{4}\times m_2=-1[/tex]
[tex]m_2=\dfrac{4}{3}[/tex]
The point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
The slope of new line is [tex]\dfrac{4}{3}[/tex] and it passes through P(-3,-15). So, the equation of line of new road is
[tex]y-(-15)=\dfrac{4}{3}(x-(-3))[/tex]
[tex]y+15=\dfrac{4}{3}(x+3)[/tex]
[tex]y+15=\dfrac{4}{3}x+4[/tex]
Subtract 15 from both sides.
[tex]y=\dfrac{4}{3}x+4-15[/tex]
[tex]y=\dfrac{4}{3}x-11[/tex]
Therefore, the equation of the line representing the new road is [tex]y=\dfrac{4}{3}x-11[/tex].

Tayler tried to evaluate the expression (22-5\times3) + 6(22−5×3)+6left parenthesis, 22, minus, 5, times, 3, right parenthesis, plus, 6. Her work is below. \begin{aligned} &\phantom{=}(22-5\times 3) + 6\\\\ \text{Step }1:\quad&=(22 -15) + 6 \\\\ \text{Step }2:\quad&=7 + 6 \\\\ \text{Step }3:\quad&=1 \end{aligned} Step 1: Step 2: Step 3: =(22−5×3)+6 =(22−15)+6 =7+6 =1
Step-by-step explanation:
Given the expression that Tayler tried to evaluate as:
[tex](22-5\times3) + 6[/tex]
We will solve this equation using PEDMAS
Multiplication before addition and subtraction
On solving:
[tex]Step \ 1\\= (22-5\times3) + 6\\= (22-(15)) + 6\\\\Step\ 2\\= (22-15) + 6\\\\Step \ 3\\= 7+6\\= 13[/tex]
From the steps above, we can see that Tayler made an error in step 3 by taking the difference of 7 and 6 and arriving at 1 instead of summing up to get 13 as shown above.
Divide. Round to the nearest tenth if necessary. 11.4 divided by 19

if f(x)=0 what is x
The value of x when f(x) = 0 in the graphed function is: C. -2, 1, or 3 only.
What is a Function?A function relates an input value (x-value) to a corresponding output value (y-value).
In the graphed function, f(x) = 0 means the value of y is 0, at this point, the values of x on the x-axis that corresponds to this y-value are -2, 1, or 3.
Therefore, if f(x) - 0, x would be: C. -2, 1, or 3 only.

A hamburger and 2 drinks cost $6.00; 2 hamburgers and 2 drinks cost $9.60.
How much does 1 drink cost?
$1.20
explanation:
h + 2d = 6
2h + 2d = 9.60
-2h - 4d = -12
2h + 2d = 9.60
- 2d = - 2.4
d = $1.20
The cost of 1 drink is required.
The cost of 1 drink is $1.20.
Let cost of 1 hamburger be [tex]x[/tex]
cost of 1 drink be [tex]y[/tex]
The equations will be
[tex]x+2y=6[/tex] [tex]\times2[/tex]
[tex]2x+2y=9.6[/tex]
[tex]2x+4y=12[/tex]
[tex]2x+2y=9.6[/tex]
Subtracting the equations
[tex]2y=2.4\\\Rightarrow y=\dfrac{2.4}{2}\\\Rightarrow y=1.2[/tex]
The cost of 1 drink is $1.20.

Do przygotowania jednej porcji gofrow potrzeba 1 i pul szklanki maki pszennej, 1i jedna trzecia szkalanki mleka oraz 0,5 szkalnki oleju pszennego. Szklanka maki wazy 16 dag, szklanka mleka-24 dag, a szklanka oleju-21,5 dag.Ile dekagramow waza lacznie skladniki potrzeba na jedna porcje gofrow?
Odpowiedź:
5,075 dekagramu
Wyjaśnienie krok po kroku:
Biorąc pod uwagę, że:
Na jedną porcję gofra:
mąka pszenna = 1 szklanka
mleko = 1 szklanka
olej pszeniczny = 0,5 szklanki
Waga na filiżankę:
1 szklanka mąki = 16 gramów
Szklanka mleka = 24 g
Dziewczęta oliwy = 21,5 g
Na jedną porcję gofra:
(1 * 16 gramów) + (1 * 24 gramów) + (0,5 * 21,5 gramów)
16 gramów + 24 gramów + 10,75 gramów
= 50,75 grama
Odwołanie :
1 gram = 0,1 dekagramu
50,75 gramów = (50,75 * 0,1)
= 5,075 dekagramu
