Answer:
Surface Area: 1090 inch²
Blue Paint needed: 545 inch²
Gold Paint needed: 545 inch²
Step-by-step explanation:
Is there a door or something? I'm assuming not because you didn't include it in your question.
Surface Area:
(7*15*2)+(15*20*2)+(20*7*2)=
210+600+280=
1090 inch²
If he paints half the doghouse blue and the other half gold then simply divide the surface area by 2:
1090÷2=545
He needs 545 inches² of blue paint
He needs 545 inches² of gold paint.
Answer:
He walks 4.5 miles per hour

Answer:
Step-by-step explanation:
<u>Amount paid for food booth</u>
- 15*$100 + 15*d*$5 = 75d + $1500
<u>Amount paid for game booth</u>
- 20*$50 + 20*d*$7 = 140d + $1000
<u>Total amount paid</u>
- 75d + $1500 + 140d + $1000 = 215d + $2500
4/105 In total there are 2+4+1+8=15 The probability of taking a blue is number of blue divided by number of total, so that would be 4/15. Since, it is not replaced, we can now say that there are 1 less marbles in the bag (since we took out a blue). Now probability of getting a green marble is:2/14=1/7
Answer:
You didn't provide answer options. The correct answer option will be the one where the ratio of red paint to yellow paint is 3:8.
Step-by-step explanation:
To make orange, you need some amount of red and some amount of yellow. As long as you mix them in the same proportions, you will get the same orange colour, regardless of how much total paint you're using. It's the RATIO between colours that matter, not how much colour is used.
In this case we are told that to make orange you can use any of the following combinations:
10.5mL red / 28mL yellow
9mL red / 24mL yellow
7.5mL red / 20mL yellow
Just take any of these and convert into a fraction. The middle option is easiest because it uses whole numbers:
This means for every 3 units of red, you need 8 units of yellow. Whichever answer option has red and yellow in that ratio is the correct answer.
