Answer:
26 socks
Step-by-step explanation:
There are a total of 48 socks here. Let us assume you pulled out 24 socks at a go and all are red. Now, you would have exhausted the number of red socks here. You would be left with only blue socks which you can pull one after the other to give a total of 26 socks pulled out to have 2 blue socks at least.
Answer:
a) Monica's error was she used the formula = Base × Height
This formula is wrong formula
b) The unit for area of a triangle is square inches not inches
Step-by-step explanation:
Monica has a triangular piece of fabric. The height of the triangle is 15 inches and the triangle's base is 10 inches. Monica says that the area of the fabric is 150 inches. What error did Monica make
The area of a triangle is = 1/2 × Base × Height
From the question
Base = 10 inches
Height = 15 inches
Area of the triangular fabric = 1/2 × 10 × 15
= 75 square inches
a) Monica's error was she used the formula = Base × Height
This formula is wrong formula
b) The unit for area of a triangle is square inches not inches
3 burritos and 4 tacos cost 11.33 3b + 4t = 11.33
<span>9 burritos and 5 tacos cost 23.56 9b + 5t = 23.56 </span>
<span>To solve: multiply top equation by 3. </span>
<span>3(3b + 4t = 11.33) becomes 9b + 12t = 33.99 </span>
<span>9b + 5t = 23.56 stays as is 9b + 5t = 23.56 </span>
<span>Now subtract the second equation from the first and you will get </span>
<span>7t = 10.43 which you can solve by dividing both sides by 7 to get t = 1.49 so a taco costs $1.49. </span>
<span>Now replace a t in either equation with 1.49 so 3b + 4t = 11.33 becomes 3b +4(1.49) = 11.33 or 3b + 5.96 = 11.33. Now subtract 5.96 from each side leaving 3b = 5.37 and finally divide both sides by 3 to get b = 1.79 so a burrito costs $1.79 </span>
<span>Problem Two: </span>
<span>3 brass and 10 steel costs $48 3b + 10s = 48 </span>
<span>7 brass and 4 steel costs $54 7b + 4s = 54 </span>
<span>To solve: multiply top equation by 2 and the bottom equation by 5 so the number of s's will be equal </span>
<span>2(3b + 10s = 48) becomes 6b + 20s = 96 </span>
<span>5(7b + 4s = 54) becomes 35 b + 20s = 270 </span>
<span>Now subtract the top equation from the bottom equation and you will get 29b = 174. Divide both sides by 29 to get b = 6. </span>
<span>Now replace the b of either original equations with the 6 (say the top equation) to get 3(6) + 10S = 48 or written another way, </span>
<span>10s + 18 = 48. Now subtract 18 from both sides to get 10s = 30 and then divide both sides by 10 to get s = 3. </span>
<span>b=6 and s=3 so each brass part is $6 and each steel part is $3.</span>
