Can someone help me with this problem!

Answer: 15 / 86

Step-by-step explanation:

First find out the total number of customers at Deion's boutique:

= 15 + 71

= 86 customers

Out of this 86, 15 customers wore a small size.

The odds of picking one of those 15 is:

= 15 / 86

Answer:

The number of questions in Mark's homework is:

Step-by-step explanation:

To identify the number of questions of the homework, first, you must identify the percentage that is the 12 question Mark calculates by himself: if in 80% he uses calculator, in 20% he doesn't, I mean, he uses his own calculates, by this reason:

With this data, we can use a simple rule of three and find the number of question that correspond to 80%.

If:

Then:

At last, we add the 80% and the 20% of the questions:

As you can see, the number of questions in Mark's homework is 60 questions.

Answer:

60° ; 30°

27.71 km

Step-by-step explanation:

Since we have a right angled triangle, and also the sum of the angles in a triangle is 180°

Angle of elevation is given as 60°

Hence, we have :

90°+60°+x ° = 180°

x = 180 - 150

x = 30°

The two acute angles are 60° and 30°

The altitude, h of the drone can be obtained thus :

Using trigonometry :

Sin θ = opposite / hypotenus

Sin 60 = h / 32

h = 32 * sin 60

h = 27.71 km

Answer:

D or the last one.

Step-by-step explanation:

Honestly, you got me kinda confused. Is it saying that there is multiple equations to answer this? Well anyways, D would be the answer. When the variable (w) is beside the coefficient, it means you multiple them together. (W) standing for weeks multiplied by 12 which is how much you earn each week would get you the total amount. The rest just don't make sense.

Answer:

6%

Step-by-step explanation:

for this is divided the fee by the price of the item.

Step-by-step explanation:

• first triangle •

the third angle = 180-56-37 = 87°

the 4 cm's side is located between angle 56° and 87°

• second triangle •

the third angle = 180-56-37= 87°

the 4 cm' side is located between angle 37° and 87°

so, both of triangles are not congruent, because the 4 cm's side is not located between the same angles

Answer:

y = mx+b

m represents the slope and b represents the y-intercept

since you have the slope and a point you can find here the line crosses the y-axis

y = -1/2x + b

the point (-14, 6) can be substituted into the eq for x and y

(6) = -1/2(-14)+b

6 = 7 +b     (subtract 7 from both sides)

-1 = b

The line crosses the y-axis at -1

Answer:

y=-1/2x-1

Step-by-step explanation:

y=mx+b

y=-1/2x+b. This is the first part. You basically plug in the slope for m. To solve for b, you have to plug in the x and y coordinates into the equation

6=(-14)(-1/2)+b

6=7+b

-1=b

So now you have your slope and your y-intercept, plug it back into the y=mx+b format

y=-1/2x-1 would be the final answer

Answer:

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

Let the no be x

By the conditions given ,

2x + 6x = 72

8x = 72

x = 72/8

x = 9

therefore the no is 9

[tex](2 \times x) + (6 \times x) = 72 \\ 2x + 6x = 72 \\ 8x = 72 \\ x = 72 \div 8 \\ x = 9[/tex]

Step-by-step explanation:

Answer: 147.71 yard³

Step-by-step explanation:

The volume of a cone is calculated using the formula:

Volume = ⅓πr²h

where,

π = 3.14

r = Diameter/2 = 8.4/2 = 4.2

h = height = 8

Volume = ⅓ × 3.14 × 4.2² × 8

Volume = ⅓ × 3.14 × 17.64 × 8

Volume = 147.71 yard³

Answer:

(a) 7/15

(b) 1/3

Step-by-step explanation:

(a) teaching:

(3 1/2) / (7 1/2) = (7/2) / (15/2) = 7/2 * 2/15 = 7/15

(b) marking:

(2 1/2) / (7 1/2) = (5/2) / (15/2) = 5/2 * 2/15 = 5/15 = 1/3
