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 teacher asked 4 students to measure 4 different objects. Here are the results
Which student had the greatest percent error?
Answer:
Student 3 had the greatest percentage error.
Step-by-step explanation:
Student 1
Actual length = 50in
Measured length = 49in
Error = 50 - 49 = 1
Error% = 1/50 × 100
= 1 × 2
= 2%
Student 2
Actual length = 100cm
Measured length = 110cm
Error = 100 - 110 = 10
Error% = 10/100 × 100
= 10 × 1
= 10%
Student 3
Actual length = 2cm
Measured length = 2.5cm
Error = 2 - 2.5 = 0.5
Error% = 0.5/2 × 100
= 0.5 × 50
= 25%
Student 4
Actual length = 10ft
Measured length = 9½ft
Error = 10 - 9½ = ½
Error% = ½/10 × 100
= ½ × 10
= 1 × 5
= 5%

5. List the transformations for the function 1/3f(x) - 2
Answer:
all of them
Step-by-step explanation:
Given that f(x) = x2 – 3x - 10 and g(x) = x – 5, find (f - g)(x) and express
the result in standard form.
Answer:
[tex](f-g)(x)= x^2-4x-5[/tex]
Step-by-step explanation:
We have the two functions:
[tex]f(x)=x^2-3x-10\text{ and } g(x)=x-5[/tex]
And we want to find (f-g)(x).
(f-g)(x) is equivalent to f(x)-g(x).
Therefore:
[tex]\begin{aligned} (f-g)(x)&=f(x)-g(x)\\ &=(x^2-3x-10)-(x-5)\end{aligned}[/tex]
Simplify:
[tex]\begin{aligned} &=x^2-3x-10-x+5 \\ &=(x^2)+(-3x-x)+(-10+5) \\ &=x^2-4x-5\end{aligned}[/tex]
Therefore:
[tex](f-g)(x)= x^2-4x-5[/tex]
Answer:
x^2 -3x+5 = 0

Which of the following is not a true bi-conditional statement?
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

8. Mohan wants to buy a trapezium shaped field.
Its side along the river is parallel to and twice
the side along the road. If the area of this field is
10500 m² and the perpendicular distance
between the two parallel sides is 100 m, find the
length of the side along the river.
Top surface of a raised platform is in the shape
ofthe octagonalourfa
Answer:
The length of the side along the river is 140 m
Step-by-step explanation:
Equations
To solve the problem, we need to recall the area of a trapezium is:
[tex]\displaystyle A=\frac{b1+b2}{2}.h[/tex]
Where b1 and b2 are the lengths of the parallel sides and h is the height of the trapezium.
The field to be bought by Mohan has a trapezium shape with a side along the road of side x and a side along the river of side 2x, as stated in the problem.
Knowing the height is h=100 m, and the area is 10500 m2:
[tex]\displaystyle \frac{x+2x}{2}\cdot 100=10500[/tex]
Simplifying:
[tex]\displaystyle (3x)\cdot 50=10500[/tex]
[tex]150x=10500[/tex]
Dividing by 150:
[tex]x = 10500 / 150 = 70[/tex]
x = 70 m
2x = 140 m
The length of the side along the river is 140 m

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

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.
