Big Smiles Toy Company needs to pack marbles into a box. The company has two boxes they can use. Box A is 9 inches wide, 13 inch

shtirl [24]

Answer:

Big Smiles Toy Company should choose Box B as its volume is 82.5 $inch^3$ larger than Box A

Step-by-step explanation:

Given

Dimension of Box A= 9 inches width, 13 inches length, 11.5 inches height

Dimension of Box B =14 inches width, 8.5 inches length, 12 inches height

Volume of Box A= Length $\times$ width $\times$ height= $9\times13\times11.5= 1345.5 inches^3$

Volume of Box B =Length $\times$ width $\times$ height= $14\times8.5\times12= 1428 inches^3$

Difference = Volume of Box B - Volume of Box A = 1428 - 1345.5 = 82.5 $inches^3$

Box B has 82.5 $inch^3$ volume larger than Box A

Mr lim had just enough money to buy 6 similar lamps. However, he bought 3 such lamps and had $950 left. How much money did mr li

Artyom0805 [142]

Let the cost of a lamp = x

6 lamps would cost 6x

He bought 3 lamps at 3x plus Thad 950 left.

3 lamps plus the 950

Would be the same amount as 6 lamps:

Set up an equation and solve for x:

3x + 950 = 6x

Subtract 3x from both sides:

950 = 3x

Divide both sides by 3:

X = 316.67

Each lamp was $316.67

Multiply the price of a lamp by 6:

316.67 x 6 = 1900

He had $1900

Winnie adds the smallest 30 positive even numbers. Grogg adds the largest 30 odd negative numbers. How much greater is Winnie's

MaRussiya [10]

Answer:

1830

Step-by-step explanation:

Sum of smallest 30 positive even numbers is given by

2 + 4 + 6 + 8 + ......... up to 30 terms

= 2 ( 1 + 2 + 3 + 4 + ....... + 30)

= $2 \times \frac{1}{2} \times (30) \times (30+1) = 930$

Again the sum of largest 30 odd negative numbers is given by

- 1 - 3 - 5 - 7 - ...... up to 30 terms.

= - (1 + 3 + 5 + 7 + ...... up to 30 terms)

{This is an A.P. series having first term 1, common difference 2 and the number of terms 30}

= $-\frac{30}{2} [2 \times 1 + (30-1) \times 2]$

= - 900

Now, Winnie has the sum 930 and Grogg has the sum - 900.

So, Winnie's sum is (930 + 900) = 1830 more than Grogg's sum. (Answer)

What additional piece of information do we need to prove that MLN ≅ OPN

mote1985 [20]

Answer:

N is the midpoint of MO

Step-by-step explanation:

Given

See attachment for triangles

Required

Additional information to prove $MLN \cong OPN$

From the attachment, we already have:

$LM \simeq OP$ and $LN \simeq ON$

The additional information that must be true for $MLN \cong OPN$ to be true is: N is the midpoint of MO

Because this piece of information proves that:

$MN \simeq ON$

Which in other words makes $MLN \cong OPN$
