Step-by-step explanation:

A skyrocket is launched from a 8-foot-high platform with an initial speed of 220 feet per second. The polynomial 16t^ ^ 2+220t+8 gives the height in feet that the skyrocket will rise in t seconds. How high will the rocket rise if it has a 7-second fuse?

The equation above is - 16t ^ 2 + 220t + 8

A) 748
B) 764
C) 788
D) 882

Answers

Given :

A skyrocket is launched from a 8-foot-high platform with an initial speed of 220 feet per second.

The polynomial -16t² + 220t + 8 gives the height in feet that the skyrocket will rise in t seconds.

To Find :

How high will the rocket rise if it has a 7-second fuse?

Solution :

Since, it is given that the rocket has a fuse time of 7 seconds.

Putting value of 7 sec in given equation, we get :

Height = -16×( 7 )² + 220×( 7 ) + 8

Height = 764 m

Therefore, height of rocket in 7 second fuse is 764 m.

Answers

I hope this is right, but I think it should take a remaining six hours for the new guy to fix your car. He worked on it for two hours with the other mechanic, but it still takes him 8 hours total to fix the car. So he still has six more hours to fix your car. Again, I hope this is right.

Not sure if this is what you’re looking for because the question is choppy and some of the letters/words are missing.

Step 2(?) the step with 15 - 3e
When combining 9 = -3e + 6, six would be subtracted from nine equaling three not fifteen.
Correct Steps:
Equation: 9 = -3 (e - 2)

Step 1: 9 = -3e + 6

Answers

Answer: 112, 68, 22, 90

Step-by-step explanation:

This is fairly somewhat easy

since the adjacent side of 1 is 68 degrees

then 1 would be 112 degrees to make it supplementary to 180 degrees

angle 3 is vertical of angle 68

making it 68 degrees

angle 5 is given to be 90 degrees meaning angle 4 is inbetween

angles 3 and 5 so ( 68 and 90 ) that'll add up to 158 meaning angle 4

is 22

angle 1 = 112

angle 3 = 68

angle 4 = 22

angle 5 = 90

13x = 3(X-20) How to solve this algebra equation?

Answers

-6x is the correct answer

Answer:

x = -6

Step-by-step explanation:

13x = 3(x - 20) {Use distributive method:a(b+c)=(a*b) + (a*c)

13x = 3*x - 3*20

13x = 3x - 60 {Subtract '3x' from both sides}

13x -3x = -60

10x = -60 {Divide both sides by 10}

x= -60/10

x = -6

30% of 50

what’s the easiest and fastest way to solve it?

Answers

Step 1: Our output value is 50.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$50=100\%$.

Step 4: Similarly, $x=30\%$.

Step 5: This results in a pair of simple equations:

$50=100\%(1)$.

$x=30\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have

$\frac{50}{x}=\frac{100\%}{30\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{50}=\frac{30}{100}$

$\Rightarrow x=15$

Therefore, $30\%$ of $50$ is $15$

Answer:

Step-by-step explanation:

change the percent to a decimal

30% to .30

.30 x 50= 15

The simplified value of the expression 6 + 4 × {3 + 7} is 100.

What is PEMDAS rule?

PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.

Given, An expression 6 + 4 × {3 + 7}.

First, we'll add 6 and 4 as 3 and 7 are inside curly brackets,

not in parentheses.

Therefore,

6 + 4 × {3 + 7}.

= 10 × {3 + 7}.

Now, we can either distribute the terms or take the addition and multiply.

= 10 × 10.

= 100.

Albert O'Malley signs a promissory note for $3,500 for 150 days at 9% exact interest. Find the interest he must pay _____ and the total amount due on the due date _____.

Answers

Answer:

He must pay $129.45 and the total amount due is $3,629.45.

Step-by-step explanation:

I (interest) =P (principal) x R (rate) x T (time)

I=3500x.09x150/365

I=129.45

A (amount due) = P (principal) + I (interest)

A= 3500 + 129.45

A= $3629.45

how they traveled to school.
The following pie chart shows
the result of the survey.
What are the number of students
that travel to school by bus?

Best Answer gonna have branliest

Answers

Answer:

(a) Since, the highest central angle 120⁰ is of the bus

hence , the most common mode of transport is the bus.

(b) Fraction of children travelling by car =

angle covered by car section

--------------------------------------------

total angle

= 90⁰ 1

--------- = ---------

360⁰ 4

= 18 = ----- × Total no. of children.......from(b)

⇒ Total no of children = 18×4

⇒ Total no of children = 72

(d) Central angle of children who do not take texi = 120⁰ +90⁰ +60⁰+60⁰

⇒ Central angle of students who do not take taxi = 330⁰

⇒ Central angle of students who do take taxi = 360⁰ −330⁰ =30⁰

30⁰

No . of children travelling by taxi = --------- × Total no of children

360⁰

30⁰

⇒ No of children travelling by taxi = --------- × 72 = 6

360⁰

(e) The central angle for students travelling by cycle and those who walk is same.

Thus , the two modes of transport are equal number of children travelling are cycle and walk.
