Answer: 1 : 3
Step-by-step explanation:
¹/₄ of the tiles are white. To find the ratio, assume the tiles are 4 in number.
If there are 4 tiles;
White = ¹/₄ * 4 = 1 white tile
Grey tiles = 4 - 1 = 3 grey tiles
The ratio is therefore;
1 white tile : 3 grey tiles
1 : 3

The amount of seed in a bird feeder decreases 10.8 ounces in 5 days. The amount of seed decreases the same amount each day. What is the change in the amount of seed in the feeder in 7 days?
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
If the amount of seed in a bird feeder decreases by 10.8 ounces in 5 days.
The change in the amount of seed in the feeder in 7 days is 15.12 ounces.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
Example:
A man can run 3 miles in 60 minutes.
The time to run 1 mile is 20 minutes.
We have,
The rate at which the amount of seed decreases.
10.8 ounces = 5 days
Divide both sides by 5.
10.8/5 ounces = 1 day
Multiply 7 on both sides.
7 x 2.16 ounces = 7 days
15.12 ounces = 7 days
This means that in 7 days, the amount of seed decreases by 15.12 ounces.
Thus,
If the amount of seed in a bird feeder decreases by 10.8 ounces in 5 days.
The change in the amount of seed in the feeder in 7 days is 15.12 ounces.

Suppose that the water level of a river is 33 feet and that it is receding at a rate
of 0.5 feet per day. What would the water level be after 15 days? Round your
answer to the nearest tenth.
Answer:
25 1/2 feet
Step-by-step explanation:
Answer:
25.5 ft
Step-by-step explanation:
Starting level: 33 ft
Each day the water recedes 0.5 ft.
Now we calculate the number of ft the water recedes in 15 days.
15 days * 0.5 ft/day = 7.5 ft
In 15 days, the water recedes 7.5 ft.
Level of water after 15 days:
33 ft - 7.5 ft = 25.5 ft
Answer: 25.5 ft
2 t-shirts and 3 hats costs £12.
5 t-shirts and 4 hats costs £23.
Find the cost of a t-shirt.
Find the cost of a hat
Answer:
Cost of tshirt = £7.29
Cost of what = £0.86
Step-by-step explanation:
2t +3h = 12; 10t + 15h = 60
5t + 4h =33; 10t + 8h = 66
15h -8h = -6
7h = -6; h = -6/7; h = 0.86
2t +3(-6/7) =12
14t -18 = 84
14t = 102; t = 102/ 14; t=7.29
The graph below plots a function f(x):
If x represents time, the average rate of change of the function f(x) in the first three
seconds is....
Answer:
-50
Step-by-step explanation:
The average rate of change is synonymous with the slope. Therefore, we will find the slope of the function from x=0 to x=3.
So, we will use the endpoints of the function.
At x=0, f(x)=150. Thus, we have the point (0, 150).
At x=3, f(x)=0. Thus, we have the point (3, 0).
Now, we can use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (0, 150) be (x₁, y₁) and let (3, 0) be (x₂, y₂). Substitute:
[tex]m=\frac{0-150}{3-0}=-150/3=-50[/tex]
Therefore, the average rate of change for the first three seconds is -50.

A.) It is noon if only if it is 12:00 PM
B.) An angle is right if and only if it’s measure is 90°.
C.) I am a violinist if and only if I am a musician.
D.) Two segments are congruent if and only if they have the same length.
well a bi conditional statement is a statement that joins P and Q together with ths use of if and only if eg P if and only if Q.
I think the answer is (A) because 12:00pm is not the only noon time. 1pm is also noon so yeah that's why I think its A

Answer:
perimeter of triangle IJH= 17.5
Step-by-step explanation:
line IJ is a midsegment, so you can divide the segments FH and GH by 2.
that means segment IH= 4.5 and segment GH=6. segment IJ is given as 7.
add 4.5 + 6 + 7, which equals 17.5

Which of the following is a root of the polynomial shown below?
f(x) = x2 + 2x2 - x-2
O A. 1
OB. 3
O c. O
O D. 2
Answer:
We conclude that option A is true as x = 1 is the root of the polynomial.
Step-by-step explanation:
Given the polynomial
[tex]f\left(x\right)\:=\:x^2\:+\:2x^2\:-\:x-2[/tex]
Let us determine the root of the polynomial shown below.
[tex]\:0=\:x^2\:+\:2x^2\:-\:x-2[/tex]
[tex]0=3x^2-x-2[/tex]
switch sides
[tex]3x^2-x-2=0[/tex]
as
[tex]3x^2-x-2=\left(3x+2\right)\left(x-1\right)[/tex]
so the equation becomes
[tex]\left(3x+2\right)\left(x-1\right)=0[/tex]
Using the zero factor principle
[tex]3x+2=0\quad \mathrm{or}\quad \:x-1=0[/tex]
solving
[tex]3x+2=0[/tex]
[tex]3x=-2[/tex]
[tex]\frac{3x}{3}=\frac{-2}{3}[/tex]
[tex]x=-\frac{2}{3}[/tex]
and
[tex]x-1=0[/tex]
[tex]x=1[/tex]
The possible roots of the polynomial will be:
[tex]x=-\frac{2}{3},\:x=1[/tex]
Therefore, from the mentioned options, we conclude that option A is true as x = 1 is the root of the polynomial.
