Answer:
2/51
Step-by-step explanation:
there are 4 white tiles and 18 total tiles in the bag, so your ratio is 4 out of 18 and 2/9 when simplified. When Robin draws out the first one, if it is white, then because he keep that one out, there are only 3 white tiles left and 17 total tiles left, so 3/17 is his chance of drawing a white the second time. you multiply 2/9 and 3/17 together because there is a chance for him to draw the white tile the first time and a chance to draw a white again the second time, so it is reasonable for the chance to be really small. 2/9 x 3/17=2/51.

Step-by-step explanation:
Marcus is tying two bows for birthday gifts. He uses 3 3/8 feet of ribbon for Crystal's gift and 2 3/4 feet for Tim's gift. If he has an 8-foot roll of ribbon, how much will Marcus have left over?
Marcus will have [tex]1\frac{7}{8}[/tex] feet as left-over.
It is important we understand that foot refers to single unit of measurement while feet is the plural of foot.
Marcus needs to tie two bows for birthday gifts and he has an 8-foot roll of ribbon.
• He uses 3 3/8 (27/8 as a fraction) feet of ribbon for Crystal's gift.
• He uses 2 3/4 (11/4 as a fraction) feet for Tim's gift.
The left-over computation is as follows:
= [tex]8 - \frac{27}{8} - \frac{11}4}[/tex]
= [tex]\frac{256-108-88}{32}[/tex]
= [tex]\frac{60}{32}[/tex]
= [tex]\frac{15}{8}[/tex] or [tex]1\frac{7}{8}[/tex] feet
Marcus will have [tex]1\frac{7}{8}[/tex] feet as left-over.

Answer:
12 in Mathematics and 16 in Science
Step-by-step explanation:
12+16=28
12+3=15 and 16-4=12
15*12=180
Answer:
He got 12 marks in mathematics and 16 in science.
Step-by-step explanation:
M + S = 28, (M + 3)(S - 4) = 180.
(M + 3)(S - 4) = MS - 4M + 3S - 12 = 180
MS - 4M + 3S - 12 = 180
MS - 4M + 3S = 192
M + S = 28
S = 28 - M
M(28 - M) - 4M + 3(28 - M) = 192
28M - [tex]M^{2}[/tex] - 4M + 84 - 3M = 192
-[tex]M^{2}[/tex] + 21M = 108
-[tex]M^{2}[/tex] + 21M - 108 = 0
(-M + 9)(M - 12) = 0
M = -9, 12
S = 37, 16
1st solution:
(-9 + 3)(37 - 4) = 180
-6 * 33 = 180
-198 = 180
2nd solution:
(12 + 3)(16 - 4) = 180
15 * 12 = 180
180 = 180
Therefore, M = 12 and S = 16.
Given the definitions of f(x) and g(x) below, find the value of (gºf)(-4).
f(x) = -2x - 3
g(x) = 2x2 – 2x – 8
Answer:
[tex](g\circ f)(-4) = 32[/tex]
Step-by-step explanation:
We are given the two functions:
[tex]f(x) = -2x - 3\text{ and } g(x) = 2x^2 - 2x - 8[/tex]
And we want to find the value of:
[tex](g\circ f)(-4)[/tex]
Recall that this is equivalent to:
[tex]\displaystyle = g(f(-4))[/tex]
Find f(-4):
[tex]\displaystyle \begin{aligned}f(-4) &= -2(-4) - 3 \\ &= 5 \end{aligned}[/tex]
Hence:
[tex]g(f(-4)) = g(5)[/tex]
Finally, find g(5):
[tex]\displaystyle \begin{aligned}g(5)& = 2(5)^2 - 2(5) - 8 \\ &= 32 \end{aligned}[/tex]
In conclusion:
[tex](g\circ f)(-4) = 32[/tex]

Classify 7/8 as either a whole number natural number an integer or rational number
Answer:
rational number
Step-by-step explanation:
a whole number is a non-negative integer, a natural number is a positive integer, an integer is any number that doesn't have decimal places and isn't a fraction. 7/8 isn't an integer so it isn't a whole or natural number. rational numbers can be written as fractions or are terminating decimals. 7/8 is a fraction so 7/8 is a rational number

I need help with geometry homework.
Use the figure to name each of the following.
1. The intersection of TV and US.
2. The intersection of US and plane R.
3. The intersection of TU and UV.
The point at which lines, planes and points meet is referred to as the point of intersection or simply intersection.
The intersection of TV and US, US and plane R & TU and UV is point U
From the attached figure, we have the following observations
1. Line segments TV and US intersects at point U.
This means that the intersection of TV and US is point U
2. Line segment US and plane R intersects at point U
This means that the intersection of US and plane R is point U
3. Line segments TU and UV intersects at point U
This means that the intersection of TU and UV is point U
Hence, the name of the three intersections is point U

1. Find the distance between the pair of points: (-8, -2) and (-4,5)
Hi, I'm happy to help!
To solve, this, we need to find the distance in x coordinates, y coordinates, then use the Pythagorean Theorem, let's solve!
First, we have to find the distance in x coordinate values. The first coordinate is -8, and the second is -4, which means there is an x distance of 4.
Next, we need to find the distance in y coordinate values. The first coordinate is -2, and the second is 5, meaning there is a y distance of 7.
From here, we use the Pythagorean Theorem. This states that a²+b²=c².
This applies to right triangles, which is what we have. The x distance is a, the y distance is b, and the overall distance is c. We need to find c to answer the question. Let's plug in our values:
4²+7²=c²
16+49=c²
65=c²
To find c, we need to find the square root of 65.
√65

Answer:
t = Gx + a
Step-by-step explanation:
G = t - a/x (Given)
G(x) = (t - a/x)x (Multiply x on both sides)
Gx = t - a (Simplify)
Gx + a = t - a + a (Add a on both sides)
Gx + a = t (Simplify)
6 . The scale of a map is 1: 250 000. (a) The actual distance between two cities is 80 km. Calculate this distance on the map. Give your answer in centimeters. (b) On the map a large forest has an area of 6 cm?. Calculate the actual area of the forest. Give your answer in Square kilometres.
Answer:
The scale of a map is 1:250000.The actual distance between two cities is 80 km. Calculate this distance on the map. Give your answer in centimetre
Step-by-step explanation:
1 m = 100 cm
1 km = 1000 m = 100 000 cm
1:250 000 mean that 1 cm on the map represents an actual distance of 250 000 cm = 2.5 km
1:250 000 = 2.5 km / cm
80 km / 2.5 km / cm = 32 cm
OR
80 km = 8 000 000 cm
8 000 000 cm ∙ 1 / 250 000 = 8 000 000 cm / 250 000 = 32 cm
