2. Doug can row 3 1/2 miles in 1/4 hour. What
is his average speed in miles per hour?
SHOW WORK!
Answer:
14 miles
Step-by-step explanation:
He can row 3.5 miles in .25 hours.
If there are 60 mins in an hour. Take the .25 hour and times by 4 to get a whole hour.
Since 3.5 miles is for .25 hr, take the 3.5 times by 4 to get what he rows in a whole hour.
3.5*4= 14 miles.

Identify the function shown in this graph.
-5 -4 -3 -2 -1
2 3 4 5
O A. y = -5x - 3
B. y = 5x - 3
O C. y = -3x + 3
D. Y = -5x + 3
Answer:
[tex]y = -5x - 3[/tex]
Step-by-step explanation:
The data in the question are not properly presented.
See attachment for graph
To determine the graph, first we need to calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where x and y are corresponding values:
When x = -1; y = 2;
This implies [tex](x_1,y_1) = (-1,2)[/tex]
When x = 0; y = -3
This implies [tex](x_2,y_2) = (0,-3)[/tex]
So:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{-3 - 2}{0 - (-1)}[/tex]
[tex]m = \frac{-3 - 2}{0 +1}[/tex]
[tex]m = \frac{-5}{1}[/tex]
[tex]m = -5[/tex]
The equation is then calculated using:
[tex]y - y_1 = m(x-x_1)[/tex]
Where:
[tex]m = -5[/tex]
[tex](x_1,y_1) = (-1,2)[/tex]
[tex]y - 2 = -5(x -(-1))[/tex]
[tex]y - 2 = -5(x +1)[/tex]
[tex]y - 2 = -5x -5[/tex]
Make y the subject
[tex]y = -5x - 5 +2[/tex]
[tex]y = -5x - 3[/tex]
Please note that the graph I attached may/may not be the right graph to your question.
However, if you follow the steps I used in answering this question, you'll get the right answer to your question.

Pacos tacos sells three tacos for $1.32 Taco Bell sell five tacos for $4.20 which is a better deal
Answer:
$0.44
Step-by-step explanation:
We find the unit rate for each taco
$1.32/3 for Pacos tacos
$4.20/5 for Taco Bell
We will then get
$0.44 per taco for Pacos tacos
$0.84 per taco for Taco Bell
$0.44 < $0.84
Pacos tacos is the better deal

a company sells kites it sells basic and designer kites 2 basic kites and 2 designer kites are 400g 4 basic kites and 1 designer are 440g work out the weight of a basic and a designer kit
Answer:
380g
Step-by-step explanation:
hope this answer will help u
The weight of basic kit is 73.33 g and weight of Designer kit 146.68 g.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
let the weight of basic kit be x and weight of designer kit be y.
The weight of 2 basic kites and 2 designer kites are 400g.
and, the weight of 4 basic kites and 1 designer kites are 440g.
So, the system of equation is
2x + 2y = 400.............(1)
4x + y = 440
y = 440 - 4x.............(2)
Solving equation (1) and (2), we get
2x + 2(440 - 4x) = 400
2x + 880 - 8x = 400
-6x = -440
x = 73.33
and, y= 440 - 4(73.33)
y = 146.68

Which statements about opposites are true?
Select each correct answer.
Answer:
(a) TRUE
(b) TRUE
(c) FALSE
(d) TRUE
Step-by-step explanation:
" The "opposite" of any number is also known as it's " additive inverse" i.e. for any number 'a' the additive inverse is 'a' ".
(a) TRUE
Since let us consider any negative number '-5' then it's opposite is '5' since (-5)+5=0
(b) TRUE
this could be seen clearly from the number line.
(c) FALSE
this statement is false since we can take example of zero.
the opposite of zero is 0 but 0×0≠1.
(d) TRUE
since 0-0=0.Step-by-step explanation:

Layla has a coin that has a 60%, percent chance of showing heads each time it is flipped. She is going to flip the coin 5 times. Let X represent the number of heads she gets. What is the probability that she gets more than 3 heads?
Answer:
0.33696
Step-by-step explanation:
Given that:
Probability of showing up head (p) = 0.6
Number of flips = number of trials = 5
Probability of getting more than 3 heads
P(x = x) = nCx * p^x * (1 - p)^(n-x)
P(x> 3) = p(4) + p(5)
P(x = 4) = 5C4 * 0.6^4 * 0.4^1 = 0.2592
P(x = 5) = 5C5 * 0.6^5 * 0.4^0 = 0.07776
Hence,
0.2592 + 0.07776
= 0.33696
Following are the calculation to the probability:
The probability to see the head [tex](p)= 60\%= 0.60[/tex]
Amount of flips = amount of tries = 5
Chances of getting and over three heads:
[tex]\to P(x = x) = ^n C_x \times p^x \times (1 - p)^{(n-x)}\\\\\to P(x> 3) = p(4) + p(5)\\\\\to P(x = 4) = ^5 C_4 \times 0.6^4 \times 0.4^1 = 0.2592\\\\\to P(x = 5) = ^5 C_5 \times 0.6^5 \times 0.4^0 = 0.07776\\[/tex]
Hence,
[tex]\to 0.2592 + 0.07776= 0.33696 \approx 0.34\\\\[/tex]
Therefore, the final answer is "0.34"

Which is greatest: 75%, 4/5, or 0.75?
Answer:
4/5
Step-by-step explanation:
75% = 75/100 = 0.75 = 3/4
4/5 = 80/100 = 80% = 0.80

75%
80% - this is the biggest
75%

Number 35, I need that answered DUE IN 1 HOUR PLZ ANSWER ASAP
Answer:
18.5
Step-by-step explanation:
It says
IJ is the midsegment of the triangle. So it divides both adjacent sides in half/at modpoint.
so HF is 10 cm .. half of that is 5 cm
GH is 13 cm.. Half of that is 6.5 cm
now we have IJ = 7 cm given
add all those.. you get 18.5 cm
Answer:
18.5
Step-by-step explanation:
35.
Segment IJ is a midsegment of triangle FGH, so
2HI = 2FI = FH
2HJ = 2JG = GH
FG = 2IJ
Perimeter of triangle IJH = IJ + JH + HI
IJ + JH + HI = 7 + 6.5 + 5 = 18.5
