Hi there!

[tex]\large\boxed{3 \text{ boxes}}[/tex]

Calculate the number of boxes of cubes needed by calculating the volume of the pictured figure.

We can see that it has a width of 4 blocks, depth of 2 blocks, and a height of 8 blocks.

Calculate volume: V = l × w × h

V = 4 × 2 × 8  = 64 cubes in each box.

Since she needs 140 cubes, we can find how many boxes she would need for this amount:

140 ÷ 64 = 2.1875.

However, you cannot buy a part of a box, which is why you must round to a whole number. However, only buying 2 boxes would be too little.

Thus, she would need to buy 3 boxes.

I had the same question and I got it right so there you go :)

Answer:

Step-by-step explanation:

Multiplying anything by zero equals zero. So if either term equals zero the equation is true.

(x-6)(x+5)=0

So if x=-5 or 6 the above is true.

x=(-5,6)

Answer:

the answers I found are 6 and -5

if you separate the two and equate them to 0 you will get the answers like this :

x - 6 = 0. or x + 5 = 0

x= 6. or x = -5

Answer:

put the value m=1/2

3m(4m+5)=3

⇒3×1/2(4×1/2+5)+3

⇒3/2(2+5)+3

⇒6/2+15/2+3

⇒37 ans.

Step-by-step explanation:

For the equation, (4m-5)(3m+3)=37 value of m are 2.21 and -1.96

Equation consist of 2 expression equivalent to each other.

Given the following equation:

(4m-5)(3m+3)=37

To calculate the value of m as follows:

4m(3m+3)-5(3m+3)=37

12m²+12m-15m-15=37

12m²-3m-52=0.................................m)

Using discriminant formula:

[tex]d=b^2-4ac.............................1\\x=\dfrac{-b\pm\sqrt d}{2a}............................2[/tex]

Here, from equation m)

a=12, b=-3, c=-52

Substituting in equation 1

d=(-3)²-4(12)(-52)

d=2505

√d=50.04

[tex]m=\dfrac{3\pm 50.04}{2\times 12}\\\\m=2.21 \text{\ and\ } m=-1.96[/tex]

Thus value of m are 2.21 and -1.96

Answer:

The p-value is;

d. 0.00131

Step-by-step explanation:

The given question parameters are;

                                                     Company A   [tex]{}[/tex]                       Company B

Sample size                                   80[tex]{}[/tex]                                         60

Sample mean   [tex]{}[/tex]                            [tex]\overline x_1[/tex] $16.75                            [tex]\overline x_2[/tex] $16.25

Population standard deviation [tex]{}[/tex]   σ₁  $1.00                           σ₂ $0.95

[tex]z=\dfrac{(\bar{x}_{1}-\bar{x}_{2})-(\mu_{1}-\mu _{2} )}{\sqrt{\dfrac{\sigma_{1}^{2} }{n_{1}}+\dfrac{\sigma _{2}^{2}}{n_{2}}}}[/tex]

Therefor, we have;

[tex]z=\dfrac{(16.75-16.25)-(0-0)}{\sqrt{\dfrac{1^{2} }{80}+\dfrac{0.95^{2}}{60}}} \approx 3.0128[/tex]

The p-value = 1 - 0.99869 (the area to the right of 3.01) = 0.00131

Answer:

D

Step-by-step explanation:

It is because you can see the line pass through the value 0 in x-axis while 6 in y-axis which gives the first coordinate (x,y) = (0,6) and the line also past through the value of 5 in x-axis and 1 in y-axis which gives the second coordinate is (1,5).

So it is true that the line did go through at points (0,6) and (1,5).

Step-by-step explanation:

Because (2 times 7) times 3 is the same as 2 times (7 times 3)

The numbers are just put different, and makes a different answer.

So, just because the answers are the same, doesn't make them commutative property,

m<1 + m<3/2 +m<4/2 =180

125+10 +m<4/2=180

135 +m<4/2 =180

m<4/2 =180-135

m<4/2 =45

m<4 = 90
