Answer:
[(6 + x) / 13+x] = 0.65
7
Step-by-step explanation:
Given that:
Total number of games = 13
Number of correct prediction = 6
Number of correct predictions needed to raise prediction % to 65%
(Number of correct predictions) / (total number of games) = 0.65
Let x = number of additional consecutive correct predictions
[(6 + x) / 13+x] = 0.65
Where x = number of consecutive predictions required
6 + x = (13 + x) * 0.65
6 + x = 8.45 + 0.65x
x - 0.65x = 8.45 - 6
0.35x = 2.45
x = 2.45 / 0.35
x = 7
7 consecutive correct predictions

Find the area of the figure
Answer:
45 I'm pretty sure. so it 45
Answer:
The figure is 5.5in^2.
Step-by-step explanation:
To find the area of the triangle portion, we will use the formula for area of a triangle, [tex]\frac{bh}{2}[/tex], where b = base and h = height.
So lets find our variables,
b = 3
h = 3
So we can plug that into our equation and find the area,
3 · 3 = 9 and 9 ÷ 2 = 4.5
So the area of the triangle is 4.5in^2
To find the area of the square portion, we will use the formula for the area of a square or rectangle, l · w, where l = length and w = width
So lets find our variables,
l = 1
w = 1
So 1 · 1 = 1in^2
To find the total area we will add the areas of the two components together,
4.5 + 1 = 5.5in^2
So the area of the total figure is 5.5in^2.
what value of r gives the line passing through (3,2) and (r,-4) A SLOPE OF 3/2
Answer:
(-6,-4)
Step-by-step explanation:
to get to -4 from 2 you have to subtract 6, making the slope x/6 but you said the slope is 3/2. divide 6 by 2 and you get 3. 3x3=9 making the slope 9/6. simplify and you get 3/2
-x+5-5x=8 pls help and I’ll give brainlluest
Answer: x = -1/2
-x + 5 - 5x = 8
⇔ -6x + 5 = 8
⇔ -6x = 3
⇔ x = 3/(-6) = -1/2
Step-by-step explanation:
Answer:
option 4
x=-1/2Step-by-step explanation:
-x +5-5x=8
-6x= 3
x= -1/2The ratio of the weight of copper and zinc in an alloy is 3:2. Find the weights of copper and zinc in the alloy of 140g.
Answer:
Given the ratio of copper and zinc in an alloy is 5:3.
Let weight of copper and zinc be 5x and 3x.
Then according to the problem we have,
5x=30.5
or, x=6.1
Then weight of zinc is 3×6.1=18.3 g.

Answer:
Function A has a greater slope than Function B.
Step-by-step explanation:
An easy way to solve this would be to graph function B and see which line is steeper. The steeper line always has greater slope.
Answer:
A
Step-by-step explanation:
its function would be y=4x+2
Xavier created a scatterplot and a trend line for data that he collected by comparing the number of minutes he spent playing a game and the number of levels he passed.
According to the graph, which combination of minutes played and levels passed seem most likely to be possible?
A) 2 minutes played and 3 levels passed
B) 17 minutes played and 35 levels passed
C) 20 minutes played and 9 levels passed
D) 50 minutes played and 19 levels passed
Answer:
Option (C)
Step-by-step explanation:
By using regression line calculator,
Equation of the regression line will be,
y = 0.4881x - 0.85714
Here y = Levels passed
x = Number of minutes played
Now we can check every option given.
Option (A)
For x = 2 minutes,
y = 0.4881(2) - 0.85714
= 0.11906
≈ 0.1
False.
Option (B)
For x = 17 minutes,
y = 0.4881(17) - 0.85714
= 8.2971 - 0.85714
= 7.44
≈ 7th level
False.
Option (C)
For x = 20 minutes
y = 0.4881(20) - 0.85714
= 9.762 - 0.85714
= 8.9
≈ 9th level
True.
Option (D)
For x = 50 minutes,
y = 0.4881(50) - 0.85714
= 24.405 - 0.85714
= 23.54786
≈ 24th level
False.
Therefore, Option (C) will be the correct option.

-3y + 8x = 36
6x + y = -21
Answer:
x=−27/26
and y=−192/13
Step-by-step explanation:
6x+y=−21;8x−3y=36
Step: Solve6x+y=−21for y:
6x+y=−21
6x+y+−6x=−21+−6x(Add -6x to both sides)
y=−6x−21
Step: Substitute−6x−21foryin8x−3y=36:
8x−3y=36
8x−3(−6x−21)=36
26x+63=36(Simplify both sides of the equation)
26x+63+−63=36+−63(Add -63 to both sides)
26x=−27
26x
26
=
−27
26
(Divide both sides by 26)

Martin drinks 1/4 of a litre of juice each day.
Juice costs £3.60 for a 2 litre carton and £2.00 for a 1 litre carton.
Martin buys enough juice to last for 2 weeks (14 days).
What is the lowest price Martin can pay for this juice?
Given :
Martin drinks 1/4 of a litre of juice each day.
Juice costs £3.60 for a 2 litre carton and £2.00 for a 1 litre carton.
To Find :
Martin buys enough juice to last for 2 weeks (14 days).
What is the lowest price Martin can pay for this juice.
Solution :
Amount of litre used in 14 days is :
V = 14× ( 1/4 )
V = 3.5 liter
Lowest price to pay is :
P = 2 × Cost of one 2 L carton
P = £(2 × 3.60)
P = £7.2
The lowest price Martin can pay for this juice is £7.2 .
Hence, this is the required solution.
The formula for area of a triangle is given by: A=bh/2 Rearrange the formula to solve for b
Answer:
b = 2A
h
Step-by-step explanation:
A=bh/2
2A = bh
b = 2A
h
Answer:
b=(2a)/h
Step-by-step explanation:
Multiply both sides by 2
2A=bh
Divide both sides by h
(2a)/h=b
