Answer:
3 and 27
Step-by-step explanation:
Step 1: Determine which two terms we can use
We have the following numbers to choose from: 3, 14, 27
Adding two numbers to get a multiple of ten means that the number that we come up with needs to be divisible by ten. For example: 20, 30, 50, 100 are all multiples of ten.
In this example the only one that would add up to create a multiple of ten is 27 and 3 which would give us 30 which is a multiple of 10.
Answer: 3 and 27

The ratio of girls to boys in the school marching band is 3 to 2. If there are 24 boys in the marching, how many of the students in the marching band are girls.
A.42
B.28
C.32
D.36
Answer:
D. 36
Step-by-step explanation:
Ratios are a way to represent of how much there is one thing to another. It's a more simplistic representation.
For example, if there were 625 adults and 375 children, we don't say there are 625 adults to 375 children, we say there are 5 adults to 3 children.
All I did was divide both the number of children and adults by 125 and we have a ratio of 5:3 for adults to children respectively.
In this problem, we have a ratio of 3:2 for girls to boys. This 3:2 ratio is a simplistic representation of the number of girls to boys. We know that there are 24 boys.
Dividing 24/2 = 12
12 is the proportion which we multiply by the ratio to get the true numbers for boys and girls.
2 * 12 = 24 boys
3 * 12 = 36 girls
So there are 36 girls in the marching band.
A dog and a cat are 200 meters apart when they see each other. The dog can run at a speed of 30 meter per second, while the cat can run at a speed of 24 meters per second. How soon will they meet if they simutaneously start running towards each other?
Answer:
They'll meet after 200 meters , if they simultaneously start running towards each other.
Step-by-step explanation:
Let x =distance travelled by dog and 200-x be the distance travelled by cat. Inorder to meet, the sum of their travelled distances shall be equal to 200 meters as they are far apart by 200 meters.
Dog: Distance =Speed x time: x=30t
Cat: Distance = 200-x
=24t
The sum of their distance travelled shall be 200 meters: 30t+ 24t= 200;54t=200;t=200/54=3.7secs
So they will meet after 3.7 seconds
To check:
Distance travelled by dog :x=30(3.7)
=111.11 meters
Distance travelled by cat: 24t=24(3.7)
=88.89 meters
Therefore since they are travelling towards each other and their distance apart is 200 meters, after 3.7 seconds they will meet because dog travelled 111.11 meters and cat travelled 88.89 meters and they covered already 200 meters as the sum of 111.11+ 88.89
=200 meters
If a rectangle has a length that is three times the width increased by 4. Find the dimensions of both the length and width if the
perimeter of the rectangle is 80 centimeters
Answer:
Step-by-step explanation:
Formula
The formula for perimeter is
P = 2L + 2w
Givens
Let the width = w
Length = 3w + 4
P = 80 cm
Solution
P = 2L + 2w
80 = 2(3w + 4) + 2w Remove the brackets
80 = 6w + 8 + 2w Combine
80 = 8w + 8 Subtract 8 from both sides
80-8 = 8w + 8-8 Combine
72 = 8w Divide both sides by 8
72/8 = 8w'8
9 = w
Answer
w = 9
L = 3*w + 4
L = 3*9 + 4
L = 31

Winifred bought a bib necklace, which is just a big necklace in the shape of a dinner bib, at a 45% discount. If the discount saved her $63, what was the necklace's original price?
$140 was the original price.
discount : 45%
45% ⇒ $63
1% ⇒ $(63/45)
1% ⇒ $1.4
original price is always 100%
100% ⇒ $(1.4*100)
100% ⇒ $140
Let the original price of the necklace be ,'x',
then,
According to the question,
(45/100)x = 6345x = 6300x = 6300/45x =140Hence ,the necklace she bought worths $140 without the discount given to her.

Answer:

Step-by-step explanation:
on plato
The equation of the parabola opening upward with a focus at and a directrix will be f(x) = 1/32(x + 9)^2 + 19. so option B is correct.
What is the equation of the parabola?The equation can be written as
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix.
Here, We have the upward parabola;
(h, k) = (-9, 7) and p = (7 - (-9))/ 2 = 8.
So the equation is
f(x) = 1/32(x + 9)^2 + 19
The equation of the parabola opening upward with a focus at and a directrix will be f(x) = 1/32(x + 9)^2 + 19. so option B is correct.

PLEASE HELP If a fair coin is tossed 9 times, what is the probability, to the nearest thousandth, of getting exactly 1 heads?
The probability of getting exactly 1 head when a fair coin is tossed 9 times is approximately 0.017, to the nearest thousandth.
To find the probability of getting exactly 1 head when a fair coin is tossed 9 times, we can use the concept of binomial probability. The probability of getting a head on a single coin toss is 1/2, and the probability of getting a tail is also 1/2.
In this case, we want to calculate the probability of getting exactly 1 head out of 9 tosses. This can be represented as a binomial probability with parameters n (number of trials) and p (probability of success).
Using the binomial probability formula:
P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)
where n is the number of trials, k is the number of successful outcomes, and p is the probability of success.
In our case, n = 9, k = 1, and p = 1/2.
Plugging these values into the formula:
P(X = 1) = (9 choose 1) * (1/2)^1 * (1 - 1/2)^(9 - 1)
P(X = 1) = 9 * (1/2) * (1/2)^8
P(X = 1) = 9 * (1/2)^9
P(X = 1) = 9/2^9
P(X = 1) ≈ 0.017
Therefore, the probability of getting exactly 1 head when a fair coin is tossed 9 times is approximately 0.017, to the nearest thousandth.
