7.5 cups of sugar to make 14 dozen cookies. To the nearest hundredth, what is the rate of cups of sugar per cookie?
Answer:
0.54 There you go!
There are 168 cookies. 14 times a dozen (12) is 168.
The ratio of cups of sugar to cookies is 7.5 to 168.
If you want to find the cups of sugar you need for 168, divide 7.5 and 168 by 168.
168/168=1
7.5/168 is about 0.04.
The cups of sugar you use for one cookie is 0.04.

Hi. Please i need help with this . No jokes .
Answer:
I) The roots are:
First Case:
[tex]x=-2\text{ or } x=-6[/tex]
Second Case:
[tex]x=2\text{ or } x=6[/tex]
II) Possible values of p are:
First Case:
[tex]p=-12[/tex]
Second Case:
[tex]p=4[/tex]
Step-by-step explanation:
We have the equation:
[tex]x^2-(4+p)x+12=0[/tex]
We know that one of the roots is three times the other.
And we want to find the roots of the equation and the possible values for p.
To find our solutions, we can use the process of factoring.
If we have an equation in the form:
[tex]x^2+bx+c=0[/tex]
We want to find two numbers, say, k and j, such that:
[tex]\displaystytle kj=c\text{ and } k+j=b[/tex]
After finding them, we can factor as such:
[tex](x+k)(x+j)[/tex]
So, -k and -j will be our zeros.
Therefore, for our equation, we will find two numbers k and j such that:
[tex]\displaystyle kj=12\text{ and } k+j=-(4+p)[/tex]
Notice that for the first criterion, we can simply list all the factors of 12.
So, according to the first equation, possible values of k and j are:
1 and 12; 2 and 6; or 3 and 4.
Then, our roots will be -1 and -12; -2 and -6; or -3 and -4, respectively.
However, remember that one of our roots is three times the other.
Therefore, the only candidates that work will be the second option.
Hence, k and j are 2 and 6.
Therefore:
[tex]k=2\text{ and } j=6[/tex]
With this information, we can now determine p. Since:
[tex]k+j=-(4+p)[/tex]
Then it follows that:
[tex]\begin{aligned}(2)+(6)&=-(4+p)\\8&=-(4+p)\\-8&=4+p\\p&=-12\end{aligned}[/tex]
Hence, our equation is:
[tex]x^2-(4+-12)x+12=0[/tex]
Or, factored:
[tex]x^2+8x+12=0 \text{ or } (x+6)(x+2)=0[/tex]
So, our roots are x=-6 and x=-2 when p=-12.
However, we also need to consider the negative factors of 12.
Factors of 12 also include -2 and -6.
Hence, our k and j can also be k=-2 and j=-6.
Then, in this case, our p is :
[tex]\begin{aligned} (-2)+(-6)&=-(4+p)\\-8&=-(4+p)\\8&=4+p\\p&=4\end{aligned}[/tex]
Therefore, for our second case, k=-2 and j=-6. Then p=4. So, our equation is:
[tex]x^2-(4+4)x+12=0[/tex]
Or, factored:
[tex]x^2-8x+12\text{ or } (x-2)(x-6)=0[/tex]
Hence, when p=4, our roots are x=2 and x=6.

factor with distributive property (no variables) 55 + 35
55 + 35 Factorized ↓
5(11 + 7)
I hope this helps u
God bless
Answer
5(11+7)
1. Find the greatest common factor of 55 and 35.
The greatest common factor of 55 and 35 is 5.
2. Divide each number (in the expression) by the common factor
55/5=11
35/5=7
3. Write the factorized expression
So you multiply 5 times 11 and 5 times 7.
So when distributing, you would multiply the number outside of the parentheses by each of the numbers in the parentheses.
The number outside is 5 and the numbers inside are 11 and 7.
So the expression is 5(11+7)
5*11=55
5*7=35
4. Check to see if you get the same answer (optional)
55+35=90
5(11+7)=5(18)=90

Step-by-step explanation:
PLEASE MAKE ME BRANLIEST
Answer:
[tex]\boxed {\boxed {\sf A. \ 0.60 \ km}}[/tex]
Step-by-step explanation:
Distance (how far the submarine travelled) can be found by multiplying the speed by the time.
[tex]d=s*t[/tex]
The speed is 2.4 kilometers per hour.
The time is 0.25 hours.
[tex]s= 2.4 \ km/hr \\t= 0.25 \ hr[/tex]
Substitute the values into the formula.
[tex]d= 2.4 \ km/hr * 0.25 \ hr[/tex]
Multiply. Note that the hours (hr) will cancel each other out.

Rudolfo has 15 toys in his toy box, and he adds 2 new toys every month. Based on this
information, which representation best shows this relationship between the number of toys
Rudolfo has in his toy box, y, and the number of months that have passed, x?
Answer:
G
Step-by-step explanation:
(x)0 months: (y)15 toys, 1:17, 2:19, 3:21, 4:23, 5:25, 6:27, 7:29, 8:31, etc.

What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Rudolfo has 15 toys in his toy box, and he adds 2 new toys every month.
Let x be the number of months and y be the total number of toys. Then the equation is given as,
y = 2x + 15
