Darcie wants to crochet a minimum of 333 blankets to donate to a homeless shelter. Darcie crochets at a rate of \dfrac{1}{15}
15
1
start fraction, 1, divided by, 15, end fraction of a blanket per day. She has 606060 days until when she wants to donate the blankets, but she also wants to skip crocheting some days so she can volunteer in other ways.
Write an inequality to determine the number of days, sss, Darcie can skip crocheting and still meet her goal.
Graph the solution set to this inequality.
Answer:
s ≤ 15
Step-by-step explanation:
1/15(60 - s) ≥ 3
4 x 15 - s/15 x 15 ≥ 3 x 15
60 - s - 60 ≥ 45 - 60
-s/-1 ≥ -15/-1
s ≤ 15
Line JK passes through points J(–3, 11) and K(1, –3). What is the equation of line JK in standard form?
7x + 2y = –1
7x + 2y = 1
14x + 4y = –1
14x + 4y = 1
Answer:
7x + 2y = 1
Step-by-step explanation:
1. Find the slope of the line.
(y2-y1)/(x2-x1) ----> (11 - (-3))/((-3) -1) ----> (11+3)/ (-3 -1) ----> 14/-4
*lets simplify into (7/-2)*
2. Write into slope intercept form.
y=mx+b (m is the slope) (b is the y intercept)
y = (7/-2)x + b
We now need to find the value of b, this can be done by plugging in values of x and y, and using algebra to solve.
11 = (7/-2)(-3) + b
11 = 10.5 + b
b = 0.5 or 1/2
slope intercept form y = (7/-2)x + 1/2
Now we convert to standard form: ax+by=c
*In this form we our a term cannot be a fraction nor can it be negative*
1. Get x and y on the same side, and since our x term is negative right now, we can make it positive by adding it on both sides.
(7/2)x + y = 1/2
2. We now want to get rid of the fraction in term a, so we multiply the entire function by two, so the denominator cancels out.
2(7/2)x + 2y = 2(1/2)
Simplify and you get
7x + 2y = 1

Answer:
The Width of the garden will be 9 feet.
Step-by-step explanation:
Given:
Manny has wood =48 feet
Length of the garden = 15 feet
The equation which can be used .
We need to find the width of the garden.
Solution :
Now Length of the garden is given we will substitute in the given equation to find the width.
Now Using Subtraction property we will subtract both side by 30 we get;
Now Using Division Property we will divide both side by 2 we get;
Hence the Width of the garden will be 9 feet.
From the set {17, 22, 27}, use substitution to determine which value of x makes the inequality true.
x - 5 < 7
A. 27
B. 22
C. none of these
D. 17
Answer:
C
Step-by-step explanation:
Solving the inequality
x - 5 < 7 ( add 5 to both sides )
x < 12
None of the given values in the set are less than 12
Then solution is option C
To avoid a storm, a passenger-jet pilot descended 0.68 mile in 0.8 minute. What was the plane's average change of altitude per minute?
Answer:
0.85 m
Step-by-step explanation:
0.68/8=A decent of 0.085 miles per 0.1 minute
So per minute 0.085x10 =0.85, our plane will have a change of 0.85 m in altitude

please help me in questions 15 and 21 with their inequalities and graph
Answer:
x >= 7 OR x < -8
n <= -3 AND n > -6
Step-by-step explanation:
15) 7x - 6 >= 43 OR 10x + 4 < -76
7x >= 43 + 6 OR 10x < -76 - 4
7x >= 49 OR 10x < -80
x >= 7 OR x < -8
you can draw based on this
for >= it is full dot for < it is like circle on the graph
you have to draw both x>= 7 , x < -8 on the same line because it is OR
so both ranges of x are possible
21) 3 + 2n <= -3 AND 1 - 3n < 19
2n <= -3 -3 AND -3n < 19 - 1
2n <= -6 AND -3n < 18
n <= -3 AND 3n > -18
n <= -3 AND n > -6
so it lies between -6 and -3

If I think of a number Takeaway one and multiplied by three what will the answer
Answer:
3(x-1)
Step-by-step explanation:
Let the number be 'x'
When I take away 1 , the number is x - 1.
When I multiply 3, the number is 3(x-1).
The number is 3(x-1).

Answer:
3 ( 917 ) = 3 ( 900 ) + 3 ( 10 ) + 3 ( 7 )
5 ( 209 ) = 5 ( 200 ) + 5 ( 0 ) + 5 ( 9 )
6 ( 347 ) = 6 ( 300 ) + 6 ( 40 ) + 6 ( 7 )
9 ( 821 ) = 9 ( 800 ) + 9 ( 20 ) + 9 ( 1 )
11 ( 142 ) = 11 ( 100 ) + 11 ( 40 ) + 11 ( 2 )
Step-by-step explanation:
Answer:
Hint(look at the first number in each part and math it with the first number in each answer.) For example, 3(937), the distributive property for that one would be 3(900) + 3(30) + 3(7). Then for 5(209) it would be 5(200) + 5(0) + 5(9), then for 6(342), it would be 6(300) + 6(40) + 6(2). Then for 9(821), it would be 9(800) + 9(20) + 9(1), and for the last one it would be 11(143), it would be 11(140) + 11(40) + 11(3). You basically distribute each amount into different place values.
Step-by-step explanation:

Farmer David has 24 chickens. He gives a quarter of the chickens to Sally and a sixth of the chickens to Patience. How many chickens does he have left?
Answer:
14
Step-by-step explanation:
One fourth is 6 and one with is 4. So 4+6=10.24-10=14.
Answer:
14
Step-by-step explanation:
If you have 24 chickens, a quarter of 24 is 6. Then, a sixth of 24 is 4. 6+4=10. 24-10=14. So, he would have 14 chickens left.

How many times does the line y=-1 touch the graph? (Ensure to draw your line on the graph)
Answer:
The answer is 2 times
Step-by-step explanation:
Well, the line y equals to negative 1 is a horizontal line that crosses through the y axis.
So, if we were to draw that line in how many times is that line intersecting or coming into contact with our graph well it's happening in these two places right here (shown in attached photo) so that would intersect two times.
Thus, The answer is 2 times

Answer:
Step-by-step explanation:
to find slope, m is slope
m=(y2-y1)/(x2-x1)
let’s use one of the coordinates here:
(50,150) and (100,150)
m= (150-150)/ (100-50)
this is the slope
if this is incorrect please notify me! Thankyou :3 have a great evening :D

Marla filled up her car's gas tank and then went on a trip. After she drove 329 miles, she filled her tank with 14 gallons of gas. If she drove the same number of miles on each gallon of gas, how many miles per gallon did she drive?
Answer:
23 1/2 miles per gallon
Step-by-step explanation:
We start with dividing 329 miles with 14 gallons because it asks to find the number of miles on each gallon of gas -
Miles
----------------------------- =
Each gallon of gas
329 ÷ 14 = 23 1/2 miles per gallon

Slope-Intercept forn. State the slope and y-intercept.
(0, -3) and (1, -1)
Equation:
Slope:
y-Intercept:
Answer:
Equation: y = 2x — 3
Slope: 2
Y-intercept: —3
Step-by-step explanation:
m=∆y/∆x
= —3—(—1)/0—1
= —2/—1
= 2
We Know: y - y0 = m (x—x0)
y — (—3) = 2 (x — 0)
y + 3 = 2x
y = 2x — 3
So
Equation: y = 2x — 3
Slope: 2
Y-intercept: —3
which of the follwong is CLOSEST to The area of the shaded part of circle V?
Answer:
A
Step-by-step explanation:
The entire circle has an area of pi * r^2
r = 10
pi = 3.14
Area = 3.14 * 10^2
Area = 314 cm^2
But that is the whole circle. What is shaded is 1/4 of the circle which 314/4
which = 78.5 cm^2
Answer: A
Answer:
A) 78.5 cm^2
Step-by-step explanation:
1. To find the shaded part of the circle (1/4), we can use a formula similar to the one we use to find the area of a whole circle, but in this case, for the 1/4 part that's shaded: [tex]\frac{1}{4} \pi r^2[/tex]. Keep in mind that pi is approximated to 3.14.
2. (Solving)
Step 1: Plug in the values.
[tex]\frac{1}{4}(3.14)(10^2)[/tex]Step 2: Simplify.
[tex]\frac{1}{4}(3.14)(100)[/tex] [tex]0.785(100)[/tex] [tex]78.5[/tex] 78.5 cm^2Therefore, the answer is A) 78.5 cm^2.
