Maria walked 3/4 of a mile. Cody walked 6/10 of a mile. How much farther did Maria walk than Cody?
Answer:
She walked 3/20 more than Cody
Step-by-step explanation:
6/10 = 12/20, 3/4 = 15/20. 15/20 - 12/20 = 3/20
Answer:
3/4 = 15/20
6/10 = 12/20
15/20 > 12/20
Maria walked a further distance of 3/20 miles than Cody.

The graph of a linear function passes through the points (-1, -1/4) and (1, -3/4). Which equation represents the function ?
The equation of the line will be given as y = -4x - (- 17/ 4).
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given that:-
The equation of the line will be given as:-
y - y₁ = m ( x - x₁)
slope m will be calculated as:-
[tex]m =\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1+1}{\dfrac{-3}{4}+\dfrac{1}{4}}=-4[/tex]
The equation will be:-
y - (1/4) = -4( x + 1 )
y = -4x - (17/4)
Therefore the equation of the line will be given as y = -4x - (- 17/ 4).

Determine the approximate ordered pair for f(x) = g(x).
There is a screenshot that I have attached and here are the options that you can answer:
(3, 12)
(3, 18)
(12, 3)
(18, 3)
The approximate ordered pair is the coordinate where both functions graph intercect
That's can be found only by observing graph.
As we observe we find that
The coordinate at where f(x)=g(x) is (3,18)
It means that
at this the values of both the functions are equal
i.e
f(3)=g(3)=18Answer:
b) (3, 18)
Step-by-step explanation:
f(x) = g(x) at the point where the two lines intersect.
From inspection of the graph, we can see that the x-value of the point of intersection is between 0 and 10. Therefore, from the options given, it must be x = 3 (since 12 > 10 and 18 > 10).
From inspection of the graph, we can see that the y-value of the point of intersection is between 10 and 20, but it's nearest to 20 than it is 10. Therefore, from the options given, it must be y = 18.
Therefore, the approximate ordered pair is (3, 18)

the area of a rectangle is always
length × width
so, here we have
8x³y³z⁷ × 7x³y⁸z⁴
since we don't have further information about the variables, we can't calculate a specific number, but we can simplify the result expression.
remember, factors with the same base can be combined (when multiplying terms of the same variable by different exponents, we summit add the exponents).
and multiplication is freely commutative : the sequence of factors does not matter.
8x³y³z⁷ × 7x³y⁸z⁴ = 8×7 × x³x³ × y³y⁸ × z⁷z⁴ =
= 56x⁶y¹¹z¹¹

Answer:
x = 143° and x = 323°Step-by-step explanation:
Solving
3tanx = -4tanx = -4/3tan values are negative in the 2nd and 4th quadrantThe base value is x = 53°In Quadrant II,
90° + 53°⇒ x = 143°In Quadrant IV,
270° + 53°⇒ x = 323°Now
we know tan53=4/3
But it's negative
So tan is either in 2nd or 4th quadrant
For 2nd Quarter
x=π/2+53=90+53=143°For 4th quadrant
x=3π/2+53=270+53=323°4. Look at the composite figure below. A vertex of the square is the center of the circle. The side

Answer:
Approximately [tex]215[/tex] square units.
Step-by-step explanation:
The area of this figure is equal to:
[tex]\begin{aligned}& \text{Area of figure} \\ =\; & \text{Area of square} \\ &+ \text{Area of circle} \\ &- \text{Area of overlap}\end{aligned}[/tex].
The area of the square is [tex]8^{2} = 64[/tex] square units.
The area of the circle of radius [tex]r = 8[/tex] is [tex]\pi\, r^{2} = 8^{2}\, \pi = 64\, \pi[/tex] square units.
Refer to the diagram attached. In this figure, the overlap between the square and the circle is a sector of radius [tex]r= 8[/tex]. The angle of this sector is [tex]90^{\circ}[/tex]- same as the measure of the interior angle of the square.
The area of this sector would then be:
[tex]\begin{aligned} & \pi\, r^{2} \times \frac{90^{\circ}}{360^{\circ}} = 16\, \pi \end{aligned}[/tex].
Therefore, the area of the figure would be:
[tex]\begin{aligned}& \text{Area of figure} \\ =\; & \text{Area of square} \\ &+ \text{Area of circle} \\ &- \text{Area of overlap} \\ =\; & 64 + 64\, \pi - 16\, \pi \\ \approx\; & 215 \end{aligned}[/tex].
Which of the following is an example of an improper fraction?
OA. 4/5
O B. 6/7
O C. 10/3
O D. 3/10
Answer: C: 10/3
Step-by-step explanation:
An improper fraction is a fraction that's top number (numerator) is bigger than the bottom number (denominator)
Answer:
10/3
Step-by-step explanation:
Improper fractions are fractions where there is a larger number in the numerator than there is in the denominator. The numerator is the number on the top of the fraction, and the denominator is on the bottom. 10 is on top and it is greater than 3, so it is an improper fraction. Improper fractions can also be simplified. 10/3 can be simplified to 3 1/3.

What is the diameter of the circle if the circumference is 18.8 cm round to the nearest tenth
Answer:
d= 6
Step-by-step explanation:
radius r = 2.9921129301276 cm
diameter d = 5.9842258602553 cm
circumference C = 18.8 cm
area A = 28.1258615432 cm2
Diameter of circle is 6cm, if the circumference is 18.8 cm
What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
The circumference of a circle is the measure of the boundary or the length of the complete arc of a circle.
The formula to find circumference is
C=2pi r
Given circumference is 18.8 cm, we need to find diameter.
To find diameter first we need to find radius
18.8=2×3.142×r
18.8=6.284r
Divide both sides by 6.284
r=2.99
We know that Diameter is two times of radius
d=2r
d=2×2.99
d=5.98=6
Hence diameter of circle is 6cm, if the circumference is 18.8 cm

Answer:
A) f(x) = |x|
B) f(x) = -|x+3| + 3
Step-by-step explanation:
Absolute value functions
The general form of an absolute value function is f(x) = a|x-b| +c
a indicates the 'amplitude' or multiplier
b indicates horizontal shift
c indicates vertical shift
The turning point of f(x) = |x| is (0, 0)
a = y/x when b = 0 and c = 0
A) f(x) = |x|
Since the turning point is still (0, 0) there is no horizontal nor vertical shift, meaning b = 0 and c = 0
We have the point (2, 2), thus a = 2/2 = 1
f(x) = a|x-b| + c
f(x) = |x|
B) f(x) = -|x+3| + 3
The turning point is at (-3, 3) b = -3 and c = +3
We have the point (3, -3), thus a = y/x = -3/3 = -1
f(x) = a|x-b| + c
f(x) = (-1) (|x-(-3)|) + (+3)
f(x) = -|x+3| + 3

your friend's house is 3.9 miles north and 5.2 miles west of your bank how far is your friend's house from the bank
Hypotenuse H we need
Apply Pythagorean theorem
H²=P²+B²H²=3.9²+5.2²H²=6.5²H=6.5miAnswer:
6.5 miles far from the bank.
Step-by-step explanation:
→ AC = 3.9 miles (perpendicular)
→ BC = 5.2 miles (base)
→ AB = x (hypotenuse)
By using Pythagoras theorem the length of AB will be,
→ (Hypotenuse)²=(Perpendicular)²+(Base)²
→ AB² = AC² + BC²
→ AB² = (3.9)² + (5.2)²
→ AB² = 15.21 + 27.04
→ AB = √(42.25)
→ [ AB = 6.5 ]
Hence, friend's house is 6.5 miles away.

79 x 31 rounding or compatible numbers . show how you estimate
Answer:
80 × 30 = 2,400
Step-by-step explanation:
We can easily round 79 up to 80 and round 31 down to 30. This would make our expression 80 × 30, which is much easier to compute. We just take 8 × 3 (which is 24) and add two zeros onto the end of the number. This yields us an answer of 2,400 which is very close to the actual multiplication of 79 × 31 which is 2,449 (only 49 more than our estimation).

what is 73 divided by 8 equal in remainder???
Answer:
9 remainder 1
Step-by-step explanation:
Not sure but uh... 73/8=9 remainder 1.
Is this what you are looking for?
73 divided by 8 equals 9 with a remainder of 1.
To find the quotient and remainder when dividing 73 by 8, we perform long division.
Here's how it works:
We start by dividing the first digit of the dividend (7) by the divisor (8). Since 7 is smaller than 8, the quotient will be 0, and the remainder will be 7.
We bring down the next digit from the dividend, which is 3, making the new number 73.
Now, we divide 73 by 8. The largest multiple of 8 that fits into 73 is 9 (8 times 9 equals 72). So, the quotient becomes 9.
We subtract 72 (8 times 9) from 73, resulting in a remainder of 1.
Therefore, 73 divided by 8 equals 9 with a remainder of 1.
