Answer:
Decimal form = 2.4 / Fraction form = 1/4
Step-by-step explanation:
We know that the farmer sold 9.6 kilograms of apples and pears where 3/4 of that weight was apples. That means that 1/4 of the 9.6 kilograms were pears. Lets divide 9.6 by 1/4 to get our answer.
9.6 / 1/4 = 2.4
Decimal form = 2.4
Fraction form = 1/4

Answer: a: true
Step-by-step explanation:
Yes, a circle can be circumscribed in quadrilateral.
What is cyclic quadrilateral?A cyclic quadrilateral is a quadrilateral which has all its four vertices lying on a circle.
we know, If opposite angles of a quadrilateral add to 180 then it is called a cyclic quadrilateral and a circle can be inscribed in it.
In this case the opposite angles add upto 180 which shows that is it is a cyclic quadrilateral.

Write an equation of the line that passes through the points (0,4) and (2,10).
Answer:
First you find the slope:
(10-4)/2 = 6/2 = 3
Then you write a point-slope equation:
y-4=3x
in slope-intercept form:
y=3x+4
Answer:
The equation of the line is y = 3x + 4.
Step-by-step explanation:
First find the slope of the line:
Slope (m) = rise / run
= difference in y coordinates / difference in corresponding x coordinates
= (10-4) / (2 - 0)
= 6/2
= 3..
The line is written as
y = m x + b
We have just found m (= 3). Now we find the value of b by substituting the point (0, 4) into this equation.
4 = 3(0) + b
b = 4.
So the required equation is y = 3x + 4.

Write the equation of the circle graphed below
Answer:
[tex](x-1)^2+(y+1)^2=0.25[/tex]
Step-by-step explanation:
From the given graph it is clear that the center of the circle is (1,-1) and the circle passing through the point (0.5,-1).
So, radius of the circle is
[tex]r=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]r=\sqrt{(0.5-1)^2+(-1-(-1))^2}[/tex]
[tex]r=\sqrt{(-0.5)^2}[/tex]
[tex]r=\sqrt{(0.5)^2}[/tex]
[tex]r=0.5[/tex]
The radius of the circle is 0.5 units.
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex]
where, (h,k) is center and r is radius.
The center of given circle is (1,-1) and radius is 0.5. So, the equation of circle is
[tex](x-(1))^2+(y-(-1))^2=(0.5)^2[/tex]
[tex](x-1)^2+(y+1)^2=0.25[/tex]
Therefore, the required equation is [tex](x-1)^2+(y+1)^2=0.25[/tex].

The sum of the 8th element and the 12th element of an arithmetic progression
is 246. The sum of the 10th and the 14th element is 298. What is the value of
the 35th term?
Answer:
448
Step-by-step explanation:
aₙ = a₁ + (n-1)d
a₈ = a₁ + (8-1)d = a₁ + 7d
a₁₂ = a₁ + 11d
a₈ + a₁₂ = 246 = 2a₁ + 18d a₁ + 9d = 123
a₁₀ + a₁₄ = a₁ + 9d + a₁ + 13d = 298 a₁ + 11d = 149
2d = 26
d = 13
a₁ = 6
a₃₅ = 6 + (35-1) x 13 = 448

A circle's circumference is approximately 44 cm.
Complete each statement using one of these values: 7, 11, 14, 22, 88, 138, 154, 196, 380, 616.
The circle's diameter is approximately cm.
The circle's radius is approximately cm.
The circle's area is approximately cm2.
these are all approximate
======================================
Explanation:
C = pi*d is the formula for the circumference. We know that C = 44 approximately, so,
C = pi*d
d = C/pi
d = 44/3.14
d = 14.01 approximately
d = 14 also approximate
take half of this to get the radius
r = d/2 = 14/2 = 7
Then use this radius to find the circle's area
A = pi*r^2
A = 3.14*7^2
A = 153.86
A = 154 rounding to the nearest whole number
Answer:
Circle's radius
[tex]r=7.00\rm cm[/tex]
Circle's diameter
[tex]d=2r=2\times7=14\rm cm[/tex]
Circle's area
[tex]a=\pi \times r^2=3.14\times 7^2=154\rm cm^2[/tex]
Step-by-step explanation:
Given information:
Circle's circumference is = [tex]44\rm cm[/tex]
We know,
Circumference of circle [tex]=2\times\pi\times r[/tex]
On substitution,
[tex]2\times3.14\times r=44\rm cm[/tex]
Circle's radius
[tex]r=7.00\rm cm[/tex]
Circle's diameter
[tex]d=2r=2\times7=14\rm cm[/tex]

Calculate Line AC showing working to 1dp
Answer:
18.1 cm
Step-by-step explanation:
Consider a segment parallel to CD and passing through B.
This segment will form a right-angle triangle with A
It's length would be equal to the length of CD (the missing length)
Height of that triangle:
11 - 4 = 7
CD² = 16² - 7²
CD² = 207
CD = sqrt(207)
AC² = AD² + CD²
AC² = 11² + 207
AC² = 328
AC = 2sqrt(82)
Which is roughly 18.1 cm

Three runners are jogging from North Augusta to Beech Island. Runner 1 runs 14 miles in 3 hours while .Runner 2 runs 16 miles in 4 hours. Runner 3 runs 15 miles in 6 hours. What is the average speed of each runner?
Answer:
Runner 1,2 and 3 ran at a average speed of 4.67 , 4 and 2.5 miles per hour respectively
Step-by-step explanation:
We can all agree that speed equals distance divided by time and we are asked to find out the average speed of this 3 people.
---Average speed of runner 1
Speed = distance / time
Since he ran 14 miles within 3 hours
S = 14/3
The average speed was 4.67 miles pet hour
---For runner 2,
Speed = distance / time
Since he ran 16 miles in 4 hours,
Average speed = 16/4
= 4 miles per hour
---For runner 3,
Speed = distance / time
Since he ran 15 miles under 6 hours,
Average speed = 15/6
= 2.5 miles per hour

Given the function defined in the table below, find the average rate of change, in
simplest form, of the function over the interval 1 < x < 5.
Answer:
180
Step-by-step explanation:
The average rate of change, in simplest form, of the function over the interval 1 < x < 5 is 18.
Find the average rate of change?The average rate of change is the change in the slope of the function, it is given by the formula,
[tex]\text{Average rate of change} = \dfrac{y_2-y_1}{x_2-x_1}[/tex]
Given to us
y₂ = f(x₂) = 27
x₂ = 3
y₁ = f(x₁) = 9
x₁ = 2
Substitute the values in the formula,
[tex]\text{Average rate of change} = \dfrac{27-9}{3-2} = 18[/tex]
Hence, the average rate of change, in simplest form, of the function over the interval 1 < x < 5 is 18.

2.0% of the mass of a 150g apple is sugar.
How much sugar is contained in I apple
The apple, weighing 150g, contains 2.0% sugar by mass. Calculating this percentage, we find out that the apple contains 3.0g of sugar.
Explanation:To find out how much sugar is contained in a 150g apple, where 2.0% of its mass is sugar, we use simple percentage calculations. We know that 1% of 150g is 1.5g (150/100), so 2.0% of 150g would be 2 times 1.5g, which comes to 3.0g. Thus, the apple contains 3.0g of sugar.
