Step-by-step explanation:
Ms. Gallegos burns 236 calories while riding her bike each hour. She wants to burn more than 590 calories riding her bike at the same rate.
Which inequality represents all possible values for t, the number of hours Ms. Gallegos must ride her bike to burn more than 590 calories?
Answer:
T > 2.5
Explaination -
t > 2.5
t < 2.5
t > 0.4
t < 0.4
Here it is given that Gallegos burns 236 calories riding her bike each hour.
She wants to burn more than 590 calories riding her bike at the same rate.
Let the time required = t hours
So
236t > 590
⇒ t > 590/236
⇒ t > 2.5
Therefore, the answer is t > 2.5
Ok for this one im really stuck and i need help.just want to make sure i understand this one.
Answer:
70 - 5√10 ft²
Explanation:
Perimeter is the distance around a two-dimensional shape.
area of rectangle: length x width
Here given:
length: (3√2 + 4√5) ft
width: (-5√2 + 5√5) ft
Solve for perimeter:
length x width
(3√2 + 4√5) x (-5√2 + 5√5)
apply distributive method
(3√2)(-5√2) + (3√2)(5√5) + (4√5)(-5√2) + (4√5)(5√5)
multiply
-15(2) + 15√10 -20√10 + 20(5)
combine
-30 -5√10 + 100
simplify
70 - 5√10
Find the length of the segment.
please help
Answer:
[tex]\sqrt{29}[/tex]
Step-by-step explanation:
Use the distance formula!
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
If we plug in the coordinates:
[tex]d=\sqrt{(3-(-2))^2+(4-2)^2} \\d=\sqrt{25+4}\\ d=\sqrt{29}[/tex]
That's our answer!
Answer: 3
Step-by-step explanation: since the negative numbers on the coordinate do not count as a whole number, we will start our count at number 1
Solve this system of equations
X=y+2
2y-3x=15
Answer:
x=-19, y=-21
Step-by-step explanation:
[tex]\begin{bmatrix}x=y+2\\ 2y-3x=15\end{bmatrix}[/tex]
[tex]\mathrm{Substitute\:}x=y+2[/tex]
[tex]\begin{bmatrix}2y-3\left(y+2\right)=15\end{bmatrix}[/tex]
Simplify
[tex]\begin{bmatrix}-y-6=15\end{bmatrix}[/tex]
Isolate y for -y - 6 = 15: y = -21
[tex]\mathrm{For\:}x=y+2[/tex]
[tex]\mathrm{Substitute\:}y=-21[/tex]
[tex]x=-21+2[/tex]
Simplify
x=-19
[tex]\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}[/tex]
[tex]x=-19,\:y=-21[/tex]
y=-21,x=-19
you can only solve this using simultaneouse solution. first, make x the subject in the second equation.2y-3x=15
In doing so x=-5+2/3y. You the multiply both equationby the co-efficient of x then you subtract the equations giving 1/3y=-7. hence y=-21.you then substitute the value for y into equation 1 where x=y+2 giving x=-19.
A pentagon has angles that measure 70 degrees 100 degrees 120 degrees 140 degrees and h. What is h
Answer:
h = 110°
Step-by-step explanation:
1) A pentagon has 5 sides that sum up to 540°. We know it is 540° because of this formula that is used to find the sum of the interior angles of any polygons. n is the number of sides.
= (n - 2) x 180
= (5 - 2) x 180
= 3 x 180
= 540°
2) We can now set up an equation.
70 + 100 + 120 + 140 + h = 540
430 + h = 540
h = 540 - 430
h = 110°
Who made an error?
The correct scale factor= ?
Answer:
reggie made an error
the correct scale factor is 2/3
Step-by-step explanation:
we want to get from A to A', B to B', and ultimately C to C'
to get there, we must multiply each value in each point by the scale factor.
let's start out with reggie's scale factor. he multiplies each value in C by 3/2 to get to C'. we can try this out with one point, e.g. A
for A: 3/2 * (-12, -6) = (-18, -9). this is not A' = (-8, -4)! thus, 3/2 cannot be the scale factor
now, onto hillary's scale factor of 2/3
for A: 2/3 * (-12, -6) = (-8, -4). this is A'! thus, hillary is correct and reggie made an error
the correct scale factor is thus hillary's: 2/3
In an ordered pair, the y-coordinate tells you how far to move from the origin parallel to the______. X-axis/y-axis
Answer:
y-axis
Step-by-step explanation:
The x-coordinate is the location of a point as measured along the x-axis. The y-coordinate is the location of a point as measured along the y-axis.
__
Another way to describe the y-coordinate is that it tells you how far to move from the origin parallel to the y-axis.

Find the equation of the line shown
Answer:
y = 2x
PRIMARY METHOD
Identify two points, find their slope, and write an equation
(1, 2) and (3, 6)
m = (y₂ - y₁)/(x₂ - x₁)
m = (6 - 2)/(3 - 1) = 4/2
m = 2
(1, 2)
y - y₁ = m (x - x₁)
y - 2 = 2 (x - 1)
y = 2x - 2 + 2
y = 2x
SIMPLER METHOD
Rise/Run
(0,0) to (1, 2) = 2/1 = 2
(1, 2) to (3, 6) = 4/2 = 2
Answer:
y = 2x
Step-by-step explanation:
The graph shows a straight line that passes trhough the origin, so it is a direct proportion relation with equation of the form y = mx.
To find the slope, use any easy-to-read point, and divide the y-coordinate by the x-coordinate. For example, use (1, 2).
m = 2/1 = 2
y = 2x

A graph is shown. Which of the following equations are represented by the graph?
Answer:
Equations II and IV
Step-by-step explanation:
See attached image.
Find the equation of the line in the form of y=mx+b, where m is the slope and b the y-intercept. Pick any two points to calculate the Rise/Run, or slope, of the line, as shown. The y-intercept, b, is the value of y when x=0. Rearrange the resulting equation, as necessary, to see if it matches any of the options. In option IV, I rearranged the answer, as it was easier to get it into the desired form of y=mx+b.
As shown, equations II and IV both match.

Given the formula, find the first five terms and the 10th term of each
sequence.
a n = -4 × 2 n-1
Can you teach me this?
Then I will try the next?
Given formula: [tex]\sf A_n= -4(2)^{n-1}[/tex]
simplify substitute the number of term by replacing n
Find first five terms:
[tex]\sf A_1= -4(2)^{1-1}[/tex] ⇒ [tex]\sf A_1= -4[/tex]
[tex]\sf A_2= -4(2)^{2-1}[/tex] ⇒ [tex]\sf A_2= -8[/tex]
[tex]\sf A_3= -4(2)^{3-1}[/tex] ⇒ [tex]\sf A_3= -16[/tex]
[tex]\sf A_4= -4(2)^{4-1}[/tex]⇒ [tex]\sf A_4= -32[/tex]
[tex]\sf A_5= -4(2)^{5-1}[/tex]⇒ [tex]\sf A_5= -64[/tex]
Tenth term:
[tex]\sf A_{10}= -4(2)^{10-1}[/tex] ⇒ [tex]\sf A_{10}= -2048[/tex]
Answer:
[tex]\sf a_1=-4\\a_2=-12\\a_3=-20\\a_4=-28\\a_5=-36\\a_{10}=-76[/tex]
Step-by-step explanation:
[tex]\textsf{Given sequence}: \sf a_n=-4(2n-1)[/tex]
This formula is for the nth term of the sequence.
Therefore, to find any term of the sequence, substitute the position of the term you wish to find as n.
For example, to find the 10th term, substitute n = 10 into the formula:
[tex]\begin{aligned}\sf a_{10} & =-4[2(10)-1)]\\ & = -4(20-1)\\ & = -4(19)\\ & = -76\end{aligned}[/tex]
To find the first 5 terms, substitute n = 1 through n = 5 into the formula:
[tex]\sf a_1=-4[2(1)-1]=-4(2-1)=-4(1)=-4[/tex]
[tex]\sf a_2=-4[2(2)-1]=-4(4-1)=-4(3)=-12[/tex]
[tex]\sf a_3=-4[2(3)-1]=-4(6-1)=-4(5)=-20[/tex]
[tex]\sf a_4=-4[2(4)-1]=-4(8-1)=-4(7)=-28[/tex]
[tex]\sf a_5=-4[2(5)-1]=-4(10-1)=-4(9)=-36[/tex]

Answer:
The last option
Step-by-step explanation:
There are 42 species in the sample
the proportions are:
frogs = 18/42 = 3/7
lizards = 18/42 = 3/7
worms = 6/42 = 1/7
The number of frogs and lizards is the same and exceeds that of worms
