Please help me with this question

Answers

Answer 1

Answer:

13.5m/s

Step-by-step explanation:

formula is v=u + at

as given:

u=3m/s

a=1.5m/s²

t=7secs

v=3+1.5(7)

v=3 + 10.5

v = 13.5m/s

The unit for velocity is m/s

Answer 2

Answer:

a) 87

b) 13.5

Step-by-step explanation:

for the first question we've been given the equation and the parameters needed

so we just input the parameters

3a+4b when a is 17 and b is 9

therefore the answer is 3*17 + 4*9

51+36=87

second question

that's an equation of motion and we've been given all the parameters we also need so we just input the parameters In the equation

v=u+at

v=3+1.5*7

v= 3+10.5

v=13.5

PLS HELP!!!! I don't understand how to answer this question!!!

Answers

Answer:

Step-by-step explanation:

Angle A and B are complementary which means they both add up to 90 degrees. Angle A is x+22 while angle B is only x. If we add both together, we can call angle A+B to be 2x+22. We can rewrite this as 2x+22=90. Take the 22 over to the other side and its sign changes so it is now 2x=90-22. 90-22=68 so now we have 2x=68. To isolate the x divide both sides by 2 which gives us x=34.

complimentary angles mean angles that add up to 90 so you could rewrite this as x + 22 + x = 90
then you can rewrite that as
2x + 22 = 90
from here on, you use inverse operations to solve for x, subtracting 22 then dividing what’s left by 2
2x = 90 - 22
2x = 68
x=34

Answer:

$25,480

Step-by-step explanation:

In one year, the car depreciates by 9% of its original value:

0.09 × $28,000 = $2520 . . . . amount of depreciation

The value at the end of one year is ...

$28,000 -2,520 = $25,480

Answer:

h = 590

Step-by-step explanation:

To find x, rearrange the equation to where h is on its own side.

Rearranged equation:

[tex]759 - 169 = h[/tex]

Since 169 added to h was to find 769, 169 subtracted from 759 represents h.

w=9

Answer:

w = 9

Step-by-step explanation:

18+4w=6w

Rearrange terms

4w + 18 = 6w

Subtract 18 from both sides of the equation

4w+18-18=6w-18

Simplify

4w = 6w-18

Subtract 6w from both sides of the equation

4w-6w=6w-18-6w

w = 9

Answers

50 oz. of 12% sugar and 30 oz. of 20% sugar is needed to produce 80 oz. of 15% sugar.

Equation

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the amount of 12% sugar and y represent the amount of 20% sugar need to produce 80 oz. of 15% sugar. Hence:

x + y = 80 (1)

Also:

0.12x + 0.2y = 0.15(80) (2)

From both equations:

x = 50, y = 30

Juanita has $25, and she makes $11 per hour. She needs at least $58 to buy new shoes. Write and solve an inequality to determine how many hours Juanita must work to be able to buy new shoes. Then interpret the solution.

Answers

Hello there! :)I'm happy to be helping you!

Answer:

Juanita must work 3 hours and above to be able to buy new shoes.

Step-by-step explanation:

Initially, Juanita has $25 and make $11 per hour

meaning, Juanita's new cash in hand after t hours is;

[tex]\tt C=25+11t[/tex]

Juanita needs at least $58 to buy new shoes;

meaning, the minimum cash Juanita should have should be $58 and above.

Simply put,

[tex]\tt C\geq 58[/tex]

[tex]---> \tt 25+11t\geq 58[/tex]

[tex]\tt --->11t\geq 58-25[/tex]

[tex]---> \tt 11t\geq 33[/tex]

[tex]----> \tt t\geq \frac{33}{11}[/tex]

[tex]---> \tt t>3[/tex]

The solution reveals that Juanita must work 3 hours and above to be able to buy new shoes.

Consider the equation y = 3x - 1
Identify the slope and y-intercept and
sketch the graph.

Answers

The slope will be the number that always sits next to x. So the slope in this case is 3/1. Which is rise over run. If it was a fraction, like 1/3, that would mean that the slope is rise one, run three.
If you want to find the y-intercept, you do that by putting a zero in for x, so you want to find the point that the line intersects the y-axis. So x would be zero, and wherever that point is is the y-intercept. In this case:
y = 3x - 1

y = 3(0) - 1

3 times 0 is zero

y = - 1 So, the y-intercept is - 1, or (0,-1)

To sketch the graph, you just place any number in for x or y (x is easier in this case), and solve it.
For example, I am going to say that x equals two.

y = 3(2)-1

y = 6-1

y = 5

So, your point to put on the graph would be (2,5) (x,y)
