5) In August, Yesenia was 4 feet tall. Each month since August, she has consistently grown 0.25 inc
How tall is Yesenia t months after August?
Answer:
Yesenia is 0.25t+4 inches tall after August.
Step-by-step explanation:
Given that:
Height of Yesenia in August = 4 feet tall
Growth rate since August = 0.25 inches
Number of months after August = t
According to given statement;
Height after August = Growth rate * Number of months + Height in August
Height after August = 0.25t + 4
Hence,
Yesenia is 0.25t+4 inches tall after August.

Solve using the Quadratic Formula for 2x2 + 5x – 3 = 0
x = -5, 7
b. X = -12,2
X = -3,42
Step-by-step explanation:
[tex] \tt{2 {x}^{2} + 5x - 3 = 0}[/tex]
⇢ [tex] \sf{2 {x}^{2} + 5x + ( - 3) = 0}[/tex]
Here , a = 2 , b = 5 & c = -3 {a is the coefficient of x² , b is the coefficient of x and c is the constant term }
Now ,
[tex] \tt{x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a} }[/tex]
⇢ [tex] \tt{x = \frac{ - 5± \sqrt{ {5}^{2} - 4 \times 2 \times ( - 3) } }{2 \times 2} }[/tex]
⇢ [tex] \sf{ x= \frac{ - 5±7}{4} }[/tex]
Taking positive ( + ) sign :
⇝[tex] \tt{x = \frac{ - 5 + 7}{4} = \frac{1}{2}} [/tex]
Taking negative ( - ) sign :
⇝[tex] \tt{x = \frac{ - 5 - 7}{4} = - 3}[/tex]
[tex] \purple{ \boxed{ \boxed{ \tt{⤑ \: Our \: final \: answer : \boxed{ \underline{ \tt{x = \frac{1}{2} , \: - 3}}}}}}}[/tex]

Three friends share the total cost of a game. Joe pays 30%, mike pays 2/5 and tony pays the rest. Who paid the most ?
Answer:
Mike pays the most.
Step-by-step explanation:
Joe pays 30%, given, and Mike pays 2/5, also given. You can covert 2/5. into a percentage by multiply both the numerator and denominator by 20 which gives you 40/100 = 40%. If Mike and Joe combined pay 40%+30% = 70%, then Tony only pays 30%. Therefore Mike would pay the most.

HELPPPPPPPPPPPPPPPPWhich statements are true about the ordered pair(-1, -4) and the system of
equations?
x - y = 3
7x – y = -3
Select each correct answer.
When (-1,-4) is substituted into the second equation, the equation
is true.
The ordered pair (-1,-4) is a solution to the system of linear
equations.
When (-1,-4) is substituted into the first equation, the equation is
true.
When (-1,-4) is substituted into the second equation, the equation
is false.
When (-1,-4) is substituted into the first equation, the equation is
false.
The ordered pair (-1,-4) is not a solution to the system of linear
equations.
Answer:
When (-1,-4) is substituted into the second equation, the equation is true.
The ordered pair (-1,-4) is a solution to the system of linear equations.
When (-1,-4) is substituted into the first equation, the equation is true.
Step-by-step explanation:
Given
[tex]x - y = 3[/tex]
[tex]7x - y = -3[/tex]
Required
What is true about [tex](x,y) = (-1,-4)[/tex]
To do this, we substitute -1 for x and -4 for y in both equations;
For [tex]x - y = 3[/tex]
[tex]-1 - (-4) = 3[/tex]
[tex]-1 + 4 = 3[/tex]
[tex]3 = 3[/tex]
Hence: [tex](-1,-4)[/tex] is true for [tex]x - y = 3[/tex]
For [tex]7x - y = -3[/tex]
[tex]7(-1) - (-4) = -3[/tex]
[tex]-7 +4 = -3[/tex]
[tex]-3 = -3[/tex]
Hence: [tex](-1,-4)[/tex] is true for [tex]7x - y = -3[/tex]

Point (21,28) is dilated by a scale factor of (-1/7) with a center of dilation on the origin. What are the new coordinates
Step-by-step explanation:
Original x-value = 21
New x-value = 21 * (-1/7) = -3.
Original y-value = 28
New y-value = 28 * (-1/7) = -4.
Hence the coordinates of the new point is (-3,-4).
Answer:
Original value of x-axis =21
New value of x-axis = 21×(-1/7) = -3
Original value of y-axis =28
New value of y-axis = 28×(-1/7) = -4
Hence, the new coordinate is (-3,-4).

The block company is to paint 257 cylindrical blocks like this one which has a radius of 1.5cm and a height of 4cm. If the paint costs $ 0.52 per cm2, what will be the total price the company will have to pay?
Answer:
Let us consider the equation of a partial disk Hence A= pi × r^2/ 2Answer:
[tex]\$3463.70[/tex]
Step-by-step explanation:
Start by finding the total surface area of one block. The surface area of this half-cylinder is:
[tex]2\cdot\frac{1}{2}r^2\pi+\frac{1}{2}\cdot2r\pi\cdot h[/tex]
Since both radius and height are given, we can solve the equation:
[tex](1.5)^2\cdot \pi +1.5 \cdot \pi \cdot 4 \approx \fbox{$25.9\:\mathrm{cm^2}$}[/tex].
Since the company is painting 257 of these, the total surface area of all the blocks will be:
[tex]({(1.5)^2\cdot \pi + 1.5 \cdot \pi \cdot 4)\cdot 257\approx \fbox{$6660\:\mathrm{cm^2}$}[/tex].
Each square centimeter costs $0.52, so the total cost the company will have to pay is:
[tex]({(1.5)^2\cdot \pi + 1.5 \cdot \pi \cdot 4)\cdot 257\cdot 0.52\approx \fbox{$\$3463.70$}[/tex].

Answer:
[tex]C=69.1^{\circ}[/tex]
Step-by-step explanation:
The Law of Cosines is given as:
[tex]c^2=a^2+b^2-2ab\cos C[/tex].
Plugging in given values, we get:
[tex]16^2=8^2+17^2-2\cdot 8\cdot 17\cdot \cos C,\\\cos C=\frac{-97}{-272},\\C=\arccos(\frac{97}{272}),\\C=\fbox{$69.1^{\circ}$}[/tex].

For the equation 2x + 7 =30, x = 3
O True
O False
Answer: False
=============================================================
Explanation:
To see if the x value is a solution or not, we plug it into the equation given
2x+7 = 30 .... original equation
2*3 + 7 = 30 .... replace every x with 3, since we claim that x = 3
6 + 7 = 30 .... multiply 2 and 3 to get 6
13 = 30 ...... add 6 and 7 to get 13
We get two different numbers on either side, so the last equation is not true. We get a contradiction or false statement. So the original equation is false when x = 3. Therefore, x = 3 is not the solution.
That's why the overall claim is false.
I just need question 2, please help
Answer: 73
Step-by-step explanation:
so i took what the angle was for the 107 and subtracted it from 180 because that's always how I did it i'm not positive if its correct but I think that's how you do it since there all the same angles on the bottom so M and Q match and the two top angles match so I think it would end up being 73 sorry if this isn't to much help.

Hector spent $41.75 for 2 DVDs that cost the same amount. The sales tax on his purchase was $3.15. Hector also used a coupon for $1.00 off his purchase. How much did each DVD cost?
Given:
Amount spent on 2 DVDs = $41.75
Sales tax = $3.15
Coupon = $1.00 off
To find:
The cost of each DVD.
Solution:
Let x be the cost of each DVD.
Then, cost of two DVDs = 2x
Amount spent of 2 DVDs = Cost of 2 DVDs + Sales tax - Coupon discount
[tex]41.75=2x+3.15-1.00[/tex]
[tex]41.75=2x+2.15[/tex]
[tex]41.75-2.15=2x[/tex]
[tex]39.6=2x[/tex]
Divide both sides by 2.
[tex]\dfrac{39.6}{2}=x[/tex]
[tex]19.8=x[/tex]
Therefore, the cost of each DVD is $19.8.
