Answer:

Step-by-step explanation:

Given:

Total length of ribbon = 1 yard

Length of ribbon used for project = [tex]\frac{1}{2}[/tex] yard

Length of ribbon the rest of ribbon is to be divided = [tex]\frac{1}{4}[/tex] yard

To find:

The number of ribbons of length [tex]\frac{1}{4}[/tex] yard that can be made = ?

Solution:

Length of ribbon left after the 1 yard ribbon is used for project can be calculated by subtracting the length of ribbon used from the initial length of ribbon.

i.e.

Length of ribbon left = [tex]1-\frac{1}{2} =\frac{1}{2}[/tex] yard

Now, number of ribbon of length [tex]\frac{1}{4}[/tex] yard can be found be dividing the length of ribbon left with the length of ribbon pieces to be cut.

i.e.

Number of ribbons:

[tex]\dfrac{\frac{1}{2}}{\frac{1}{4}}\\\Rightarrow \dfrac{1}{2}\times 4 = 2[/tex]

Answer:

y = -6x + 6

Step-by-step explanation:

y = mx + b

y = -6x + 6

The equation in slope-intercept form for the line with slope -6 and y-intercept 6 is y = -6x+6

The slope intercept formula y = mx + c is used when you know the slope of the line to be examined and the point given is also the y intercept (0, c).

Given that, a line has slope -6 and y-intercept 6.

The general form of the slope-intercept form for the line is y = mx+c, where m is the slope and c is the y-intercept.

Therefore, the required equation will be =

y = -6x+6

Hence, the equation in slope-intercept form for the line with slope -6 and y-intercept 6 is y = -6x+6

Answer:

for the domain, find the point on the farthest side (the left) and the closest (the right)

so for yours it would be [-3,2]

it's brackets because the points are closed.

for the range, same thing but for the y intercept.

so it's [-2,4]

there's your answer!

Answer:

∠3 = 117°

Step-by-step explanation:

∠5 and ∠3 are same side interior angles, this means that they are supplementary.

∠5 + ∠3 = 180°

∠3 = 180° - 63°

∠3 = 117°

Answer:

New depth = 1,107 feet

Step-by-step explanation:

1) Let us first calculate the total number of feet the submarine rose in 15 minutes using the rate of rise.

rate = 14.76 feet per minute

This means that at every minute, the submarine rose by 14.76 feet.

1 minute = 14.76 feet

∴ 15 minutes = 14.76 × 15 = 221.4 feet

2) To find the new depth, we will subtract the number of feet risen from the initial depth.

initial depth = 1,328.4 feet

rise after 15 minutes = 221.4 feet

New depth = 1,328.4 - 221.4 = 1,107 feet

Answer:

1/6

Step-by-step explanation:

ive seen that question b4

2 pounds of flour are required to make 1 recipe, as of the given condition.

Given that
8 1/4 pounds of flour are used to make 4 1/8 paper-mâché pasta recipe how much flour is used in one recipe is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

Flour = 8 1/4
Flour = 8.25 pounds
The proportion of the recipe made corresponding to 8.25 pounds of flour = 4.125
Now,
For 1 recipe = 8.25 / 4.125 = 2 pounds of flour are needed.

Thus,  2 pounds of flour are required to make 1 recipe, as of the given condition.

Answer:

Slope is [tex]\frac{1}{4}[/tex] and intercept is -2.

Step-by-step explanation:

Slope if the multiplied before the x (so [tex]\frac{1}{4}[/tex]).

Intercept is the standalone number (so -2).

Answer:

11: 2

12: 4

Step-by-step explanation:

11: the rate of change is the slope, which is the rise/run, so it is in this case 2/1, which simplifies to 2

12: again, using rise/run method, go down two spaces and left one (since the slope is 2/1,) which takes you to (0,4), and since the y-value is 4, the y-intercept is 4

Answer:

YZ = 30

Step-by-step explanation:

In Δ XYZ

∵ P is the centroid

∴ XC, YB, and ZA are the medians of the triangle

∵ Each median bisects its base

∴ A is the mid-point of XY

∴ B is the mid-point of XZ

∴ C is the mid-point of YZ

∵ C is the mid-point of YZ

∴ YC = ZC

∵ YC = 15

∴ ZC = 15

∵  YZ = YC + ZC

∴ YZ = 15 + 15

∴ YZ = 30

∴ The length of YZ is 30

Answer:

20%

Step-by-step explanation:

First, add 1,200, and 300. That gives you 1,500. You want to find how much percent of 1,500 equals 300, and that is 20%.

Answer:

25%

Step-by-step explanation:

1. You have a total of 1,200 students and a fraction of them did not wear their school colors, 300 students.

2. You would write the fraction [tex]\frac{300}{1200}[/tex].

3. After you divide or simpify  [tex]\frac{300}{1200}[/tex] you get [tex]\frac{1}{4}[/tex].

4. To get a percent you multiply by 100, so [tex]\frac{1}{4}[/tex] times 100 is equal to 25.

Answer:

Please find attached the required graph of the inequality representing the temperatures yeast will NOT thrive

Step-by-step explanation:

The given parameters are;

The temperature range, y, in which yeast thrives is 90°F ≤ y ≤ 95°F

Therefore, the temperature range, y', in which yeast will not thrive is 90°F > y  and y > 95°F

The graph of the inequality that represents the temperature is therefore given as shown in the attached drawing.

Answer:

Picture shown below

Step-by-step explanation:

Yeast thrives in temperatures within the temperature range of 90°F to 95°F. Any temperature above or below those limits hinders yeast production. An inequality to represent where yeast will not thrive is shown, where x represents the temperatures where the yeast will not thrive.
