Maddie Evans drove 180 miles in the same matter I'm not detect a turbo propeller plane to travel 690 miles the speed of the plane was 170 mph faster than the speed of the car find the speed of the plane
Answer:
let
m = the speed of Mattie
d1 = 180 mi the distance Mattie traveled
p = the speed of the plane
d2 = 630 mi the distance the plane traveled
the speed of the plane was 150 mph faster than the speed of the car
p = m + 150
since speed = distance/time => time = distance/speed
d1/m = d2/p
180/m = 630/p cross multiply
180p = 630m divide both sides by 90
2p = 7m
by solving the system of equations
p = m + 150
2p = 7m
we find
p = 210 mph
The speed of the plane was 210 mph
twice a number x divided by 4 is 9
Answer: 18
18 x 2 = 36
36 / 4 = 9
Answer:
2x/4 = 9
x = 18
Step-by-step explanation:
Twice a number x divided by 4 is 9
2x/4 = 9
2x = 36
x = 18
The slope of the line below is 1.5. Write the equation of the line in point-slope
form, using the coordinates of the labeled point. Do not use parenthesis on
the y side.
(4,3)
Answer:
[tex] y - 3 = 1.5(x - 4) [/tex]
Step-by-step explanation:
Given:
Slope = m = 1.5
Coordinates of labelled point = (a, b) = (4, 3)
Point-slope equation takes the form of [tex] y - b = m(x - a) [/tex].
Therefore, to write the equation, substitute a = 4, b = 3 and m = 1.5 into [tex] y - b = m(x - a) [/tex].
Thus:
[tex] y - 3 = 1.5(x - 4) [/tex]
A right rectangular prism has a base with sides 6 cm and 8 cm. If the volume of the prism is 624 cm^3, find the height of the prism.
Answer:
H=13cm
Step-by-step explanation:
Volume=Length x Width x Height
V=624cm^3
L=8cm
W=6cm
8cm x 6cm= 48cm^2
624cm^3 divided by 48^2= 13cm
H=13cm

Sam picks corn on his uncle's farm. His uncle pays him $0.40 per basket for the first 50 baskets of corn that he picks in a day and $0.50 per basket for all baskets picked over 50. On Friday Sam picked 120 baskets of corn. How much did he earn?
Answer:
$55
Step-by-step explanation:
Find out the number of baskets paid at $0.5/basket:
Since the first 50 are paid for $0.4, and he picked 130 baskets, we can subtract 50 from 120, giving us 70.
Finding the amount paid at $0.4/basket:
50*$0.4 = $20
Finding the amount paid at $0.5/basket:
70*$0.5 = $35
Total = $55

Answer:
Put "<" between -0.171100011 _____ -0.171100010
Step-by-step explanation:
-0.171100010 is greater than -0.171100011 because they are negative numbers so -0.171100011 is further than -0.171100010 to 0, therefore -0.171100010 is greater.

Answer:
(a) 10.2 ft
Step-by-step explanation:
The total surface area S is the sum of the base area and the lateral area. The base area is the area of the two triangular bases, which have a "base" of 6 ft and a height of 4 ft.
area of 2 bases = 2(1/2)bh = bh = (6 ft)(4 ft) = 24 ft²
The lateral surface area is the sum of the areas of the three rectangular faces. That will be ...
total face area = (4 ft)(x) +(6 ft)(x) +(7.2 ft)(x) = (17.2 ft)(x)
So, the total surface area is ...
200 ft² = 24 ft² + (17.2 ft)(x)
176 ft² = (17.2 ft)x . . . . . . . . . . subtract 24 ft²
(176 ft²)/(17.2 ft) = x ≈ 10.2 ft . . . . . divide by the coefficient of x
The unknown prism height is about 10.2 ft.

I think it’s 63.
I divided to get its simplified version. 14÷2 is seven, which would be 1/9. Multiply the denominator by seven, which is 63. You can also look up online to check that. 14 is indeed 2/9 of 63.

Which of the following notations correctly describe the end behavior of the polynomial graphed below?
Answer:
Step-by-step explanation:
B. As x approaches negative infinity, f(x) appoaches positive infinity.
As x approaches positive infinity, f(x) approaches negative infinity.
For the given polynomial the end behaviour are -∞ and ∞. The correct option is (B).
How to find the end behaviour for a polynomial?A polynomial is defined as the algebraic expression having all the powers to its terms as whole number. In order to find the end behaviour of a polynomial p(x), determine its value for two cases when x approaches to infinity and minus infinity.
From the graph of the polynomial given in the problem it can be observed as,
As the value of x approaches ∞ , f(x) becomes -∞.
And, as the value of x approaches -∞ , f(x) becomes ∞.
Hence, the end behaviour are given as -∞ and ∞.

If , what is the truncation error for S3? 0.610 0.774 1.476 1.640
ANSWER: D
Answer:
D
Step-by-step explanation:
Unit Test Review
The truncation error for S3 is 1.640
The correct option is (D)
What is Truncation error?Truncation error is the difference between a truncated value and the actual value.
Given:
[tex]\sum[/tex](1/4)(9/10)^n = 2.25
For S3, put n= 1 to 3
9/40 + 81/400 + 729/4000
