A triangle with vertices at A (0,2), B(12,-5), (12,9)

You go to the store and pick out 3 apples for $0.60 each, 2 bananas for $0.50 each, and 1 quart of yogurt for $4.50. At checkout

Answer:

I'm not 100% sure but I think it's $6.20

Step-by-step explanation:

First you add up the apples which equals $1.80 then you add up the bananas which equals $1.00 then you add the yogurt together which amounts to $4.50. After that you add all of that together which totals to $7.30.

For the sake of finding the percentage we're gonna move the decimal point to the very end. ( so its 730.0). Now in order to find 15% we have to find 10%. To find 10%, you move the decimal point over one (73.00). So 10% of 730 is 73. 10% + 5% = 15%. And half of 10% is 5%. So, we cut 73 in half so now we have 36.5. Now we add 36.5 to 73 (because 10% + 5%=15%) I'm just gonna round 36.5 to 37, and 73+37= 110. Now we move the decimal point back so its $1.10. Now we subtract $1.10 from $7.30 which is equal to $6.20. So your answer is $6.20.

(I'm rlly bad at explaining things so sorry if this wasnt clear enough. Also I'm not the best at math but I guess I know percentages.)

A wall is 20 feet long and requires 1,470 bricks to build. How high is the wall?

Arte-miy333 [17]

Answer: The height of wall is 10.5 feet.

Step-by-step explanation:

Since we have given that

Number of bricks to build = 1470

Length of wall = 20 feet

We need to find the height of wall.

As we know that

Bricklayer's formula is given by

$N=7LH\\\\1470=7\times 20\times H\\\\1470=140\times H\\\\\dfrac{1470}{140}=H\\\\10.5\ ft=H$

Hence, the height of wall is 10.5 feet.

You and your friend Sam are going to paint your 300 square feet room together.

Elza [17]

Fraction that Sam painted in 1 min is:
10/25=2/5
Fraction that you painted in 1 min:
5/25=1/5

Fraction pained by both in 1 min:
1/5+2/5=3/5 ft²/min
Time taken to paint 50 ft² will be:
time=3/5×50=30 min
Thus we conclude that Sam was wrong.

I wonder if I did #9 right and I’m having trouble with #10

yaroslaw [1]

Let's see....

QUESTION: Add. Write your answer as a mixed number in simplest form.

$6 \frac{7}{9} + 9 \frac{8}{9}$

1. Rewriting our equation with parts separated

 $=6+ \frac{7}{9} +9+ \frac{8}{9}$

2. Solving the whole number parts

 $6+9=15$

3. Solving the fraction parts

 $\frac{7}{9} + \frac{8}{9} = \frac{15}{9}$

4. Reducing the fraction part, 15/9,

 $\frac{15}{9} = \frac{5}{3}$

5. Simplifying the fraction part, 5/3,

 $\frac{5}{3} = 1\frac{2}{3}$

6. Combining the whole and fraction parts

 $15+1+ \frac{2}{3} =16 \frac{2}{3}$

ANSWER: $16\frac{2}{3}$

Hope that helps!
