A car travles at a speed of 44mph for 15 minutes. Calculate how far it travles.
Answer:
11 miles
Step-by-step explanation:
Answer:
11 m
Step-by-step explanation:
Speed = 44 mph
Time = 15 minutes = 15/60 = 1/4 hour
Distance = Speed * time
= 44 * [tex]\frac{1}{4}[/tex]
= 11 m
Find the equation of straight line passing through the point:
a) (4,8) and parallel to the line 3x+y=17
b) (2,3) and perpendicular to the line y=2x+13
I need the answers ASAP please!
Answer:
See solution below
Step-by-step explanation:
Standard equation of a line in point slope form is expressed as y-y0 = m(x-x0)
m is the slope
c is the intercept
Fr the equation 3x+y = 17
y = -3x+17
m = -3
Given the point (4,8)
The equation of the line is expressed as;
y - 8 = -3(x-4)
y - 8 = -3x + 12
y + 3x = 12+8
y+3x = 20
This gives the required equation
For the equation y = 2x + 13
Slope m = 2
Since the line is perpendicular to the unknown line;
M = -1/2
Given the point (2, 3)
Get the equation
y - 3 = -1/2(x - 2)
2(y-3) = -(x - 2)
2y-6 = -x+2
2y+x = 2 + 6
2y+x = 8
This gives the required equation

Answer: y = 3
Step-by-step explanation:
Any horizontal line parallel to the x-axis has a zero slope. The horizontal line passing through (-2 ,3) has equation y = 3 as it passes through all points in the plane with a y-coordinate of 3, as may be seen in the graph

Solve the simultaneous equations
5x + y = 11
3x - y = 9
Answer:
Step-by-step explanation:
5x + y = 11 -------------------(I)
3x - y = 9 -----------------(II)
Add equation (I) & (II)
5x + y = 11
3x - y = 9 {add and y will be eliminated and we'll get the value of x}
8x = 20
x = 20/8
x = 2.5
Plugin x = 2.5 in equation (I)
5*2.5 + y = 11
12.5 + y = 11
y = 11 - 12.5
y = -1.5
After solving the equations simultaneously we get the value [tex]x=\frac{5}{2}[/tex] and [tex]y=\frac{-3}{2}[/tex].
What are equations ?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign .
We have,
[tex]5x + y = 11[/tex] [tex].......... (i)[/tex]
[tex]3x - y = 9[/tex] [tex]...........(ii)[/tex]
To solve we will multiply equation [tex](i)[/tex] by [tex]3[/tex] and equation [tex](ii)[/tex] by [tex]5[/tex],
[tex]15x + 3y = 33[/tex] [tex]..........(iii)[/tex]
[tex]15x -5y = 45[/tex] [tex]..........(iv)[/tex]
Now, adding both equations [tex](iii)[/tex] and [tex](iv)[/tex] ,
We get,
[tex]8y=-12[/tex]
[tex]y=-\frac{3}{2} =1.5[/tex]
Now putting value of [tex]y=-\frac{3}{2} =1.5[/tex] in equation [tex](i)[/tex] ,
[tex]5x+(\frac{-3}{2} )=11[/tex]
[tex]x=\frac{5}{2} =2.5[/tex]
So, using the elimination method we find out the value [tex]x=\frac{5}{2}[/tex] and [tex]y=\frac{-3}{2}[/tex], which was find out simultaneously.
Hence, we can say that after solving the equations simultaneously we get the value [tex]x=\frac{5}{2}[/tex] and [tex]y=\frac{-3}{2}[/tex].

Answer:
[tex] - 11 \frac{1}{2} [/tex]
Step-by-step explanation:
8x + 5y = 7
4x - 5y = 11
If you all it all up we have
8x + 4x +5y - 5y = 18
12x=18
x=18/12=1.5=3/2 = 1 whole number 1 over 2(1 1/2)
subtituting the value of x into equation 1(8x + 5y = 7)
8(1.5) + 5y = 7
5y=7-12
5y = -5
y=-5/5
y= -1

Answer:
1st pic:
x = 60
y = 50
2nd pic:
y = 8
∠W = 28
∠Y = 128 degrees
∠X = 24
Step-by-step explanation:
first pic:
to find x, subtract 120 from 180 ⇒ 180 - 120 = 60
to find y, add 60 & 70 & subtract the sum from 180 ⇒ 180 - (60 + 70) = 50
2nd pic:
to find ∠Y, subtract 52 from 180:
180 - 52 = 128
to find y, use the following equation:
3y + 4y - 4 + 128 = 180
combine like terms:
7y + 124 = 180
subtract 124 from each side:
7y + 124 - 124 = 180 - 124
7y = 56
divide 7 on both sides:
[tex]\frac{7y}{7} = \frac{56}{7}[/tex]
y = 8
now we can find angles W and X
∠W = 4y - 4
we know that y = 8 so just substitute 8 for y
∠W = 4 x 8 - 4
∠W = 28
∠X = 3y
likewise, subtitute 8 for y
∠X = 3 x 8
∠W = 24
to check, add all angles and if they add up to 180, then its right:
24 + 28 + 128 = 180
180 = 180
Step-by-step explanation:
here's your solution
=> for first figure , (x + 120° ) = 180° [ linear pair]
=> x = 180° - 120°
=> x = 60°
=> now , we know sum of all angles of traingle = 180°
= >so, 60° + 70° + y = 180°
=> y= 180° - 130°
=> y = 50
now in figure second
=> 4y - 4 + 3y = 52° [ exterior angle equal to sum of two opposite interior
=> 7y - 4 = 52°
=> 7y = 52° + 4°
=> 7y = 56°
=> y = 56°/7
=> 8°

Members of a soccer team raised $1719 to go to a tournament. They rented a bus for
$1051.50 and budgeted $44.50 per player for meals. Write and solve an equation
which can be used to determine z, the number of players the team can bring to the
tournament.
Answer:
44.5x + 1051.5 = 1719
x = 15
Step-by-step explanation:
DeltaMath
The number of players the team can bring to the tournament is 15.
Given:
The total amount of money raised by the soccer team = $1719
Amount to rent the bus = $1051.50
Amount budgeted for each player's meal = $44.50
To find:
Equation and the number of players the team can bring to the tournament
Solution:
The number of players the team can bring to the tournament = z
Amount budgeted for each player's meal = $44.50
Total amount needed for z number of players' meals = $44.50z
Amount to rent the bus = $1051.50
The total amount of money raised by the soccer team = $1719
The equation for numbers of players will be written as:
[tex]\$44.50z+ \$1051.50= \$1719\\\$44.50z= \$1719- \$1051.50\\\$44.50z=\$667.50\\z=\frac{\$667.50}{\$44.50}=15[/tex]
The number of players the team can bring to the tournament is 15.

x° = 29°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relevant trig relationships. Here, you have the hypotenuse and the side opposite the unknown angle. So, the appropriate relation is ...
Sin = Opposite/Hypotenuse
sin(x°) = 12/25
x° = arcsin(12/25) ≈ 28.69°
The value of x is about 29.
.The measures of the angles of a triangle are in the extended ratio 6: 1: 5. What is the measure of the largest angle?
Answer:
90
Step-by-step explanation:
Ratio = 6 : 1 : 5
Angles are 6x ,x , 5x
Sum of all the angles of the triangle = 180
6x +x +5x = 180
12x = 180
x = 180/12
x = 15
Largest angle = 6x = 6*15 = 90

Mia is collecting boxes to help her friend move. She found a box that is 4 ft. Wide, 3 ft. High, and 2 ft. Long. How much space would the box take up in the moving truck?
Answer: 24 ft³
Step-by-step explanation:
To calculate the amount of space that the box will take up in the moving truck, we are simply meant to calculate the volume. This will be:
= Length × Width × Height
= 2 × 4 × 3
= 24 ft³
Therefore, the space that the box will take up in the moving truck is 24 ft.
Every week for 40 weeks, Abeke earned $76 selling ice cream and 35$ delivering newspapers. Write a numerical expression to show how much money Abeke earned in 40 weeks.
Answer: 40 x (76+35)
Step-by-step explanation:
Given: Every week Abeke earned,
$76 by selling ice cream
$35 by delivering newspapers.
i.e. Total amount earned in 1 week = $ (76+35)
Now Total amount earned in 40 weeks = 40 x (76+35)
The numerical expression to show how much money( in dollars) Abeke earned in 40 weeks = 40 x (76+35)
We have to simplify it to get the total money earned in 40 weeks i..e. $4440.
