Answer:

5/9

Step-by-step explanation:

Answer:

5/9

Step-by-step explanation:

4/9 + 1/9

To add fractions, you need a common denominator. You already have a common denominator of 9, so just add the numerators.

4/9 + 1/9 = 5/9

Since there is no common factor of 5 and 9 other than 1, the fraction is already reduced.

Answer: 5/9

Answer:

2/7x - 18

Step-by-step explanation:

-2/7x - 11 + 4/7x - 7

rearrange the expression so it's easier to add, optional

-2/7x + 4/7x - 11 - 7

2/7x - 18

Step-by-step explanation:

Since line NL is not necessarily congruent to MQ (labelled with different congruent marks), triangle NLM is not congruent to triangle MQP.

Instead, triangles NLM and QPM are congruent.

This could true because of the markings of the triangles' sides and angles are in the same location.

But the statement labeled the lines wrong which makes them False

Answer:

y=(4/3)x-8

Step-by-step explanation:

Slope-intercept form: y=mx+b

4x-3y=24

3y=4x-24 (isolating the 3y)

y=(4/3)x-8 (dividing both sides by 3)

Step-by-step explanation:

The null and the alternative hypothesis are:

[tex]\mathbf{ H_o: \rho = 0} \\ \\ \mathbf{H_1: \rho \ne 0}[/tex]

The test statistics is as follows:

[tex]t = \dfrac{r\sqrt{n-2} }{\sqrt{1-r^2}}[/tex]

[tex]t = \dfrac{0.4 \sqrt{30-2} }{\sqrt{1-0.4^2}}[/tex]

[tex]t = \dfrac{0.4 \sqrt{28} }{\sqrt{0.84}}[/tex]

t = 2.3094

The critical value

[tex]t_{\alpha/df} = t_\ \{0.05/2 \ , \ 30-2 \} } \\ \\ = t_{0.025,28} = \pm 2.048 ( from \ the \ t-tables)[/tex]

Decision rule:

To reject [tex]H_o[/tex] if t > [tex]t_{\alpha/df}[/tex].

So since t > [tex]t_{\alpha/df}[/tex]. we reject [tex]H_o[/tex] at ∝ = 0.05

Answer:

4/5 of 3 = 12/5

2/9 of 20 = 40/9

Step-by-step explanation:

Answer:

1.  2.4

2. 4.444

Step-by-step explanation:

First, let's look at 4/5 of 3. We can set it up like this:

Next, multiply the 3 by the 4 to get this:

Then, if a calculator is permitted, we get the answer of 2.4.

The next thing to do would be to repeat the steps for 2/9 of 20.

[tex]20 * \frac{2}{9}[/tex]

[tex]\frac{40}{9} = 4.444[/tex]

Answer:

77°

Step-by-step explanation:

From the question given above, the following data were obtained:

Cos α = 0.93

Sine θ = 0.26

Tan β = 0.84

α + β + θ =?

Next, we shall determine the value of α. This can be obtained as follow:

Cos α = 0.93

Take the inverse of Cos

α = Cos¯¹ 0.93

α = 22°

Next, we shall determine the value of θ. This can be obtained as follow:

Sine θ = 0.26

Take the inverse of Sine

θ = Sine¯¹ 0.26

θ = 15°

Next, we shall determine the value of β. This can be obtained as follow:

Tan β = 0.84

Take the inverse of Tan.

β = Tan¯¹ 0.84

β = 40°

Finally, we shall determine the value of α + β + θ . This can be obtained as follow:

α = 22°

θ = 15°

β = 40°

α + β + θ = 22 + 40 + 15

α + β + θ = 77°

-What is the value of Co

-What is the value of Cu

Answer:

- the value of the cost overage Co is  $ 0.3

- the value of the cost shortage Cu is  $ 0.40

Step-by-step explanation:

Given that;

Revenue per unit R                         =       $ 1.00

Cost per Unit C                               =       $ 0.60

Salvage value per unit  S                =       $ 0.30

Mean Demand μ                              =          193

Standard Deviation of demand  σ  =          41

-To get the value of our cost overage Co;

we simply say

Co = Cost per Unit C - Salvage value per unit  S  

Co = 0.6 - 0.30 = 0.30

therefore the value of the cost overage Co is  $ 0.30

- To find the value of Cost Shortage Cu;

Cu = Revenue per unit R - Cost per Unit C

Cu = 1.00 - 0.60 = 0.40

therefore the value of the cost shortage Cu is  $ 0.40

☯ [tex] \underline{ \underline{ \sf{To \: find}}} : [/tex]

[tex] \text{Given \: Equation : \: 3(x - 2) + 4 = x - 5}[/tex]

You must distribute first ! In this equation , you have the distributive property on left hand side of the equation. You must first get rid of the parentheses.

⇢ [tex] \text{3 × \: x - 3× 2 + 4 = x - 5} [/tex]

⇢ [tex] \text{3x - 6 + 4 = x - 5}[/tex]

On the left hand side , you have two numbers : - 6 and 4. Remember that ' The negative and positive numbers are subtracted but posses the sign of the bigger number. '

⇢[tex] \sf{3x - 2 = x - 5}[/tex]

Move x to left hand side and change it's sign.

Similarly , move 2 to right hand side and change it's sign.

⇢[tex] \sf{3x - x = - 5 + 2}[/tex]

On the left hand side , you have like terms. Combine the like terms : 3x - x = 2x

⇢[tex] \sf{2x = - 5 + 2}[/tex]

On the right hand side , - 5 + 2 = -3

⇢[tex] \sf{2x = - 3}[/tex]

Divide both sides by 2

⇢[tex] \sf{ \frac{2x}{2} = - \frac{3}{2} }[/tex]

⇢[tex] \boxed{\sf{x = - \frac{3}{2} }}[/tex]

-----------------------------------------------------------------

✏ CHECK :

[tex] \text{3(x - 2) + 4 = x - 5}[/tex]

Substitute [tex] \sf{ - \frac{3}{2}} [/tex] for x into the original equation. And simplify !

⇾ [tex] \sf{3( - \frac{3}{2} - 2) + 4 = - \frac{3}{2} - 5}[/tex]

⇾[tex] \sf{3( \frac{ - 3 - 2 \times 2}{2} ) + 4 = \frac{ - 3 - 5 \times 2}{2}} [/tex]

⇾[tex] \sf{3( \frac{ - 3 - 4}{2} ) + 4 = \frac{ - 3 - 10}{2}} [/tex]

⇾[tex] \sf{3( \frac{ - 7}{2} ) + 4 = \frac{ - 13}{2}} [/tex]

⇾[tex] \sf{ \frac{ - 21}{2} + 4 = \frac{ - 13}{2}} [/tex]

⇾[tex] \sf{ \frac{ - 21 + 4 \times 2}{2} = \frac{ - 13}{2}} [/tex]

⇾[tex] \sf{ \frac{ - 21 + 8}{2} = \frac{ - 13}{2}} [/tex]

⇾[tex] \sf{ \frac{ - 13}{2} = \frac{ - 13}{2}} [/tex]

Since both sides are equal , x = [tex] \boxed{ - \sf{ \frac{ 3}{2} }}[/tex] is the correct answer.

Answer:

A. 19

Step-by-step explanation:

edge 2020

The dot product of the vector u and v is 19 if option (A) is correct.

It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.

We have:

On a coordinate plane, vector u has an origin (0, 0) and terminal point (7, 8). Vector v has origin (0, 0) and terminal point (negative 3, 5).

Vector u = <(7-0, (8-0)> = <7, 8>

Siimilarly, v = <-3, 5>

u · v = (7×(-3)) + (8×5) = -21 + 40 = 19

Thus, the dot product of the vector u and v is 19 if option (A) is correct.

Answer:

x=3

Step-by-step explanation:

4x−2(x−4)=−3+4x+5

4x+(−2)(x)+(−2)(−4)=−3+4x+5

4x+−2x+8=−3+4x+5

(4x+−2x)+(8)=(4x)+(−3+5)

2x+8=4x+2

2x+8−4x=4x+2−4x

−2x+8=2

−2x+8−8=2−8

−2x=−6

−2x /−2 = −6 /−2

Answer:

4/9

Step-by-step explanation:

Let the amount of 95% sol = a ml and

the amount of 30% sol = b ml.

So, the total amount of the compound=a+b=500 ml

As the compound is 50% solution, so

95% of a + 30% of b= 50% of (a+b)

(95/100)a+(30/100)b=(50/100)(a+b) [from equation (i)]

95a + 30b = 50(a+b)

95(a/b)+30 = 50(a+b)/b [dividing both sides by b]

95(a/b)+30 = 50(a/b+1)

95(a/b)+30 = 50(a/b)+50

95(a/b)-50(a/b)=50-30

45(a/b)=20

a/b=20/45

a/b=4/9

Therefore, a:b=4:9

As a+b= 500 ml, so the amount of 95% sol = [tex]\frac {500}{13}\times 4=\frac{2000}{13}=153.85[/tex] ml

and the amount of 95% sol = [tex]\frac {500}{13}\times 9=\frac{4500}{13}=346.15[/tex] ml

Hence, the proportion of 95% sol and 30% sol to make a compound of 50% sol must be 4/9.

12 kg

Answer:

12kg

Step-by-step explanation:

When finding 15% of something you can set it up like this

?      15

---    ----

80  1000

to figure out what the '?' is you need to multiply diagonally and divide the neighbor

80 x 15 = 1200

1200 / 100 = 12

Hence, your answer is 12 kg
