Make x the subject of this formula.
y= 5(t + x)
Step by step pls
Answer:
x = [tex]\frac{y-5t}{5}[/tex]
Step-by-step explanation:
y = 5(t + x) ← distribute parenthesis by 5
y = 5t + 5x ( subtract 5t from both sides )
y - 5t = 5x ( divide both sides by 5 )
[tex]\frac{y-5t}{5}[/tex] = x

OB.
(5.1)

(-3,-1)
O C. 4.
OD.
Answer:
D
Step-by-step explanation:
We can first eliminate options A and B because they are both negative slopes and the graph shown is an increasing slope, meaning the answer is positive.
Next, we calculate the slope with the formula (y2 - y1) / (x2 - x1) to get 1/4.
1/4 is the slope.

Answer:
What value of x is in the solution set of 3(x - 4) = 5x + 2?
Solution:
3(x - 4) = 5x + 2 [Given]
Using the distributive law of multiplication on LHS
3x - 12 = 5x + 2
By grouping the similar terms on either sides and solving for x, we get
3x - 5x = 2 + 12
- 2x = 14
Divide both sides by -2 (by division property of equality)
(- 2x/2 )= 14/2
-x = 7
Therefore, the value of x is -7.

A projectile’s maximum height is shown by the vertex of the parabola. When does the cannonball reach its maximum height? Round to the nearest whole number and remember to include units.
=========================================================
Explanation:
I'll be using x in place of t
The equation given is y = -4.9x^2 + 19.8x + 58
It is of the form y = ax^2 + bx + c which is the standard form for quadratics.
We have,
a = -4.9b = 19.8c = 58Plug the first two values into the equation below
h = -b/(2a)
h = -19.8/(2*(-4.9))
h = 2.0204081632653
That value is approximate.
Rounding to the nearest whole number gets us roughly h = 2
Recall that (h,k) is the vertex of the parabola. In this case, it's the highest point. The cannonball reaches the highest point at roughly 2 seconds.
-----------------
Extra side notes:
To find the maximum height, plug the h value into the original equation. This will yield the value of k.To find the cannonball's flight time, plug in y = 0 and solve for x. Ignore the negative x solution.The figure below is dilated with the center of dilation at the origin and a scale factor of 1/2.

Lena has 1.6kg of sugar.She uses 470g for a cake.
How much sugar does she have left?
Answer: 1130 grams.
Step-by-step explanation:
She has 1130 grams remaining after converting 1.6kg to grams (160 0grams).
Answer:
1.13kgStep-by-step explanation:
=> 1 kilogram = 1000 gramsconvert into grams
=> 1.6 × 1000multiply 1000 by 1.6
=> 1600Now substract 470g from it
=> 1600 - 470subtract 470 from 1600
=> 1,130gconvert the g back into kg
=> 1130 ÷ 1000divide 1130 by 1000
=> 1.13kg1/3 (1632 + x) = 726 solve for x
pLS help please i beg i plea plssss
[tex] \frac{1}{3} (1632 + x) = 726[/tex]
[tex] \frac{1}{3} (x + 1632) = 726[/tex]
[tex] \frac{1(x + 1632)}{3} = 726[/tex]
[tex] \frac{x + 1632}{3} = 726[/tex]
[tex]3· \frac{x + 1632}{3} = 3·726[/tex]
[tex]x + 1632 = 3·726[/tex]
[tex]x + 1632 = 2178[/tex]
[tex]x + 1632 - 1632 = 2178 - 1632[/tex]

How long is the arc intersected by a central angle of StartFraction 5 pi Over 3 EndFraction radians in a circle with a radius of 2 ft? Round your answer to the nearest tenth. Use 3. 14 for Pi. 2. 6 ft 7. 0 ft 10. 5 ft 31. 4 ft.
The length of the arc of the circle with a radius of 2 ft and the angle made at the centre equal to [tex]\dfrac{5\pi}{3}[/tex] is 10.5ft.
What is the length of the arc of a circle?The length of the arc of a circle is equal to the product of the circumference of the circle and the ratio of the angle made by the arc of the circle to 2π. It is given by the formula,
[tex]\text{Length of the arc}= 2\pi r\times \dfrac{\theta}{2\pi}[/tex]
It is given that the radius of the circle is equal to 2 ft while the angle made by the arc at the centre of the circle is equal to [tex]\dfrac{5\pi}{3}[/tex]. And we know the formula for the length of the arc, therefore, the length of the arc,
[tex]\text{Length of the arc}= 2\pi r\times \dfrac{\theta}{2\pi}[/tex]
[tex]= 2\pi \times 2 \times \dfrac{\frac{5\pi}{3}}{2\pi}\\\\= 10.471 \approx 10.5\rm\ ft[/tex]
Hence, the length of the arc of the circle with a radius of 2 ft and the angle made at the centre equal to [tex]\dfrac{5\pi}{3}[/tex] is 10.5ft.

How much interest does a $482 investment earn at 5.5% over three years?
Answer:
If I'm not wrong I belive it would be like this -->
482x5.5x3=$72.3
So your answer would be $72.3!
Simple interest is the amount of interest charged on a given principal at a given rate and for a given period of time.
The interest earned with an investment of $482 at a rate of 5.5% over 3 years is $79.53.
What is simple interest?Simple interest is the amount of interest charged on a given principal at a given rate and for a given period of time.
We have,
P = Principal = $482
R = Rate = 5.5%
T = Time = 3 years
The formula for finding the simple interest is given:
SI = (P x R x T) / 100
The amount of interest from a $482 investment at 5.5% over 3 years:
= (482 x 5.5 x 3) / 100
= 7953 / 100
= 79.53
Thus,
The interest earned with an investment of $482 at a rate of 5.5% over 3 years is $79.53.

Leiff goes online to buy a new video game. He finds a site that currently has a promotion of 15% off on all orders over $50. Leiff decides to buy his video game, with a price tag of $128, at this site because he knows that he will get the 15% discount when he checks out. Leiff pays 5. 3% sales tax on the discounted price and pays a shipping fee of $4. 75. What is the total of Leiff’s online purchase? a. $112. 84 b. $114. 57 c. $118. 82 d. $119. 32 Please select the best answer from the choices provided A B C D.
Answer:
yea what the other guy said
The total of Leiff’s online purchases will be $119.32.Option d is correct.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
If the video game's original price is $128 and the discount is 15%, then Leiff paid (100-15) = 85% of the original price for the item.
Consequently, the video game's price is as follows:
(0.85 x 128) = $108.80.
Leif must contribute an additional 5.3% of the new price, so
(100 + 5.3) = 105.3% of the new price
= (1.053 x 108.8) = $114.57
Including the video game's shipping cost,
114.57 + 4.75 = $119.32
Thus, the total price is $119.32

Jake wants to know if his basketball team has gotten better. Last season, Jake's team won 10 out of 20 games. This season, his team won 15 out of 25 games. Which season had the greater ratio of games won to total games?
Answer:
This season
Step-by-step explanation:
Lowest Common Multiple (LCM) of 20 and 25 = 100
10/20 * 5/5 = 50/100 = 5/10
15/25 * 4/4 = 60/100 = 6/10

Answer:
[tex]686.6 cm^2[/tex]
Step-by-step explanation:
From the volume we can find the surface area of one of the triangle sides, by dividing it by its height. You find out that the surface of the triangle face is [tex]\frac {866}{20}=43.3 cm^2[/tex]. Let's pick two of them since we have two side faces (one close to us in the image, one far away), for a total area of [tex]86.6 cm^2[/tex]. At this point we need to add the area of the rectangular faces, which are three rectangles of length 20 and height 10, for a grand total of [tex]3\times10\times20 = 600 cm^2[/tex].
