Jessica prepared 36 kilograms of dough after working 6 hours. How much dough did Jessica prepare if she worked for 8 hours? Assume the relationship is directly proportional.
Answer:
48
Step-by-step explanation:
because 36 divided by 6 is 6 and that is how much dough she produces in an hour so if you added two more 6s to 6 to make it 8 meaning you are adding 12 because that is how much dough she makes in an hour

If p varies directly as
the cube of q, and p =
26 when q = 2, find p
when q = 5
Answer:
The value of p at q = 5 is 406.25
Step-by-step explanation:
∵ p varies directly as the cube of q
→ That means p ∝ q³
∴ The equation of variation is p = kq³, where k is the constant of variation
∵ p = 26 when q = 2
→ Use them to find the value of k
∵ 26 = k(2)³
∴ 26 = k(8)
∴ 26 = 8k
→ Divide both sides by 8
∴ [tex]\frac{26}{8}=\frac{k}{8}[/tex]
∴ 3.25 = k
→ Substitute it in the equation of variation
∴ p = 3.25 q³ ⇒ equation of variation
∵ q = 5
→ Substitute it in the equation of variation to find p
∴ p = 3.25 (5)³
∴ p = 406.25
∴ The value of p at q = 5 is 406.25
Joy makes 6.5 litres of soup, correct to the nearest 0.5 litres.
She serves the soup in 280ml portions, correct to the nearest 10ml.
22 people order this soup.
Does joy definitely have enough soup to serve 22 people?
Show how you decide.
Your final line must be written as,Joy definitely does have enough soup or Joy may not have enough soup.
I tried so hard to answer it but it isn't right so if you give me an answer please explain it so next time I will have a similar type of question I will know how to do it.
This is what i tried
6250:275=22.8 (1 d.p)
Answer:
She can serve up to 22 people
Step-by-step explanation:
Given that the total amount of soup that Joy makes in liters is 6.5L
also that the portions are in ml
280ml to liters we have 280/1000= 0.28L
our aim is to know weather 6.5L divided by 0.28L can be up to 22
let us try it out
6.5/0.28= 23.214
we have 23.
Therefore the 6.5L can serve up to 22 portions of 280ml in 6.5 L of soup
what is the slope of a line perpendicular to the line whose equation is 2x-y=-6
Answer:
m⊥ = –½
Step-by-step explanation:
First, put the given equation in slope-intercept form:
2x – y = –6
–y = –2x – 6
y = 2x + 6
The slope of the line perpendicular to the line given will be the negative reciprocal of the given line's slope, so:
If m = 2, then m⊥ = its negative reciprocal:
m · –1
2 · –1
–2 → –½
So, the negative reciprocal of 2 is –½.
The wavelength of violet light is 4.0 x 10^−7 m. The wavelength of red light is 6.5 x 10^−7 m. How much longer is the wavelength of red than violet?
A 2.5 × 10^–7 m
B 1.05 × 10^–7 m
C 2.5 × 10^–6 m
D 1.05 × 10^–6 m
Answer:
A 2.5 × 10^–7 m
Step-by-step explanation:
Given
wavelength of violet light = 4.0 x 10^−7 m.
The wavelength of red light = 6.5 x 10^−7 m
To find the how much longer is wavelength of red light than violet light we have to find difference of wavelength of red and violet light
Difference in wavelength of red light and violet light =
wavelength of red light -wavelength of violet light
= 6.5 x 10^−7 m - 4.0 x 10^−7 m
Difference in wavelength of red light and violet light = (6.5 - 4.0)*10^−7 m
Difference in wavelength of red light and violet light =2.5 x 10^−7 m
Thus,
wavelength of red light is 2.5 x 10^−7 m longer than wavelength of violet light

Can you find the numbers as powers with the given bases as your clue? Example: the number is 64 and the base is 4. I test 4x4=16 Then 16x4=64 So my power must be 43 because 4x4x4=64. Now you try... 1. It has a value of 32; it has a base of 2 2. 81, base 9 3. 81, base 3 4. 100, base 10
Step-by-step explanation:
For 32:
The factors are as shown:
32 = 2*2*2*2*2
32 = 2²*2³
32 = 2²⁺³
32 = 2⁵ (Base of 2 and power of 5)
For 81:
factors
81 = 3*3*3*3
81 = 3²*3²
81 = 3²⁺²
81 = 3⁴ (Base of 3 and power of 4)
For 100:
factors
100 = 10*10
100 = 10² (Base of 10 and power of 2)

Evaluate: -8/9 + 4/9 - 2/9
A. -14/9
B. -2/3
C. 10/9
D. -1/3
Answer:
-2/3
Step-by-step explanation:
Add the first two then subtract
The answer to the equation is B, [tex]-\frac{2}{3}[/tex]
First, you must add the the fractions. You add the numerator because all three fractions have like denominators.
[tex]-\frac{8}{9} +\frac{4}{9} -\frac{2}{9}=\frac{6}{9}[/tex]
Then, you must simplify [tex]-\frac{6}{9}[/tex]
[tex]-\frac{6}{9} =-\frac{2}{3}[/tex]
The answer to the equation is [tex]-\frac{2}{3}[/tex]

Use the distributive property to simplify the expression, then combine like terms -12 - 5p +2(6p+p)
Answer:
-12 + 9p
Step-by-step explanation:
Original Equation:
-12 - 5p + 2(6p + p)
Distributive property.
2 x 6p = 12p
2 x p = 2p
Equation:
-12 - 5p + 12p + 2p
Subtract 5p from 12p
-12 + 7p + 2p
Add.
-12 + 9p

Which lines are perpendicular to the line y - 1= 1(x+2)? Check all that apply
y2= -36% -4)
y-5=9(x - 11)
• y=-3x-2/
y = 1x-2
3x + y=7
) Intro
Done
Step-by-step explanation:
Given the line y-1 = 1(x+2), in order to know the line that is perpendicular to the given line, we will first find the slope of the known line.
The standard form of equation of a line is expressed as y = mx+c
m is the slope
c is the intercept
Rewrite the equation given
y-1 = 1(x+2)
y-1 = x+2
y = x+2+1
y = x+3
Comparing to the standard form, the slope m = 1.
For two lines to be perpendicular, the product of their slope must be -1 i.e mM = -1
Substitute
1(M) = -1
M = -1
For us to know the line that is perpendicular to the given line, its slope must be -1.
Since none of the equation has a slope of -1, hence none of the lines are perpendicular to the line y - 1= 1(x+2).

The perimeter of a kite can be found using the formula P = 2S + 2L. Which equation expresses S in terms of P and L?
Answer:
Step-by-step explanation:
P = 2S + 2L
2S + 2L = P
2S = P - 2L
S = [tex]\frac{P-2L}{2}[/tex]
Answer:
0.5P - L
Step-by-step explanation:
P = 2S + 2L
P - 2L = 2S +2L - 2L
P - 2L = 2S
0.5P - L = S

If -2z+3=9 what is the value of 2/3z?
Please Explain the steps.
Answer:
-2
Step-by-step explanation:
1.Subtract 3 from both sides and the equation is -2z=6
2.Divide both sides by -2 and the equation is z=-3
3.Multiply -3 by 2/3 and you get -2
Answer:
2/3z = -2
Step-by-step explanation:
1. First you want to find out what z is, so you have to solve for z.
2. To solve for z, first subtract 3 from the 3 and the 9. 3 minus 3 is equal to 0, so it cancels out. 9 minus 3 is equal to 6.
3. The new equation is -2z = 6, so now you have to divide -2z by -2 and 6 by -2. -2z divided by -2 is equal to 1z or z, and 6 divided by -2 is equal to -3.
4. The simplified equation is z = -3.
5. Now that we solved for 1z, we have to solve for 1/3 by dividing 1 by 3 and -3 by 3. 1 divided by 3 is 1/3, and -3 divided by 3 is -1.
6. We have solved for 1/3z (1/3z = -1), but now we want to solve for 2/3z so we have to multiply 1/3z by 2, and -1 by 2. 1/3z times 2 is 2/3z, and -1 times 2 is equal to -2.
7. The simplified equation for the value of 2/3z in the equation -2z + 3 = 9 is 2/3z = -2

If you have a liquid with a density of 14.2 g/ml and is 84.5g, what is the volume?
[tex]density = \frac{mass}{volume} \\ [/tex]
[tex]14.2 = \frac{84.5}{v} \\ [/tex]
Multiply sides by v
[tex]14.2 \times v = 84.5[/tex]
Divided sides by 14.2
[tex]v = \frac{84.5}{14.2} \\ [/tex]
[tex]v = 5.95 \: \: ml[/tex]
