A diver is on a springboard that is 4 meters above the surface of the pool. another diver is 5 meters below the surface of the pool. Who is closer to the surface of the pool?
Answer:
A
Step-by-step explanation:
Let's say the surface of the pool is 0, and the diver 4 meters above represents +4, and the diver 5 meters below represents -5. Which number is closer to 0? It's 4! 4 is 4 numbers away from 0, meanwhile 5 is 5 numbers away from zero, 4 is closer to 0!
The school cafeteria sells two types of wraps vegetarian and chicken the vegetarian wrap costs $1.00 and the chicken wrap costs $3.40 today they made $266.20 from the 103 wraps sold how many wraps sold were vegetarian
Answer:
35
Step-by-step explanation:
Let's make a system of equations for the vegetarian and chicken wraps; one for the total cost of them and one for the total amount sold.
Vegetarian wraps will be represented by variable v and chicken wraps will be represented by the variable c.
v + 3.40c = 266.20 v + c = 103Subtract these equations.
2.40c = 163.20Divide both sides by 2.40.
c = 68Substitute this value for c into the second equation.
v + (68) = 103Subtract 68 from both sides.
v = 35The number of vegetarian wraps sold amounted to 35 in total.
Answer :
The school cafeteria sold 35 vegetable wraps.Step-by-step explanation:
Let the count of vegetarian wraps be xLet the count of chicken wraps be y.Then for the count we have :
→ count of vegetarian wraps + count of chicken wraps = 103
→ x + y = 103......[Equation (i)]
Then for the cost we have :
→ ❲$1.00 * x❳ + ❲$3.40 * y❳ = $266.20
Dropping the dollar signs we get :
→ ❲1.00 * x❳ + ❲3.40 * y❳ = 266.20
→ x + 3.40y = 266.20.....[Equation (ii)]
Substracting equation (i) from equation (ii) we get :
→ 0 + 2.4y = 163.2
→ 2.4y = 163.2
→ y = 163.2 ÷ 2.4
→ y = 68
Now, subsitute the value of y = 68 in equation (i) we get :
→ x + y = 103
→ x + 68 = 103
→ x = 103 - 68
→ x = 35
Hence, the school cafeteria sold 35 vegetable wraps.a square dance set requires 4 couples 8 dancers with each couple standing on one side of a square. There are 250 people at a square dance. What is the greatest number of sets possible at the dance?
Given:
1 set requires 4 couples 8 dancers.
Total number of people at a square dance = 250.
To find:
The greatest number of sets possible at the dance.
Solution:
We have,
Total people = 250
1 set = 8 people.
[tex]\text{Number of possible sets}=\dfrac{\text{Total people}}{\text{People required for 1 set}}[/tex]
[tex]\text{Number of possible sets}=\dfrac{250}{8}[/tex]
[tex]\text{Number of possible sets}=31.25[/tex]
Number of possible sets cannot be a decimal or fraction value. So, approx. the value to the preceding integer.
[tex]\text{Number of possible sets}\approx 31[/tex]
Therefore, the number of possible sets at the dance is 31.

A quality control inspector has drawn a sample of 19 light bulbs from a recent production lot. If the number of defective bulbs is 1 or less, the lot passes inspection. Suppose 30% of the bulbs in the lot are defective. What is the probability that the lot will pass inspection
Answer:
0.0016283
Step-by-step explanation:
Given that:
Proportion of defective bulbs, p = 30% = 0.3
Sample size, n = 19 bulbs
Probability that the lot will pass inspection :
P(none of the 19 is defective) Or P(only one of the 19 is defective)
P(none of the 19 is defective) = (1 - p) ^n = (1 - 0.3)^19 ; 0.7^19
0.7^19 = 0.0011398
P(only one of the 19 is defective) :
P(1 defective) * P(18 not defective )
(0.3) * (1 - 0.3)^18
0.3 * 0.7^18
0.3 * 0.001628413597910449 = 0.0004885
Hence,
P(none of the 19 is defective) + P(only one of the 19 is defective)
0.0011398 + 0.0004885) = 0.0016283

Answer:
I think the answer is B. The equation has infinitely many solutions.
Step-by-step explanation:
4(3x + 4) = 15x + 12 - 3x + 4
*group like terms so 4(3x+4) = 15x - 3x + 12 + 4
*add similar elements 15x - 3x = 12x
*add the numbers 12 + 4 = 16
*Expand to 12x + 16 - 16 = 12x + 16 - 16
*You simplify 12x = 12x
*Subtract 12x from both sides
*Then Simplify which is 0
Which means Both sides are equal to 0

Answer:
132 units
Step-by-step explanation:
the area of triangle = 1/2 × 6 × 8 = 24 units >>>1
the area of the rectangle = 3 × 8 = 24 units >>>2
the area of rectangle(2) = (21-(9+3)) × 8 = 9 × 8 =72 units >>>3
the area of triangle(2) = 1/2 × 3 × 8 = 12 units >>>4
