area of triangle: 1/2 x base x height
area of rectangle: width x height
-> Area of 2 triangle: (1/2 x 3 x 3)x2 = 4.5 (i multiply by 2 because there 2 triangle that have the same sides)
-> Area of 1 triangle: 1/2 x 8 x 2= 8
-> Area of rectangle: 8x3= 24
====> 4.5 + 8 + 24 = 36.5 cm2

3x+y=-2
Step-by-step explanation:
A parallel line has the same slope as y=-3x-6, so a slope of -e

A group of friends are canoeing along a river. They want to travel upstream 1.5 km, then travel back downstream back to their original starting point. The river has a current of 6km / h * r If the distance equation to find the time to travel upstream is time = and the equation to (velocitycurrenty distance travel downstream is time = ( velocity current) How fast should the canoe be traveling to complete the journey in 6 hours ? b. If the journey upstream ends up taking twice as long as the journey downstream, how fast did the canoe travel ?
Answers
Using the relation between velocity, distance and time, it is found that:
a) The canoe should be traveling at a rate of 37.5 km/h.b) The canoe traveled at a rate of 6.124 km/h.What is the relation between velocity, distance and time?Velocity is distance divided by time, hence:
[tex]v = \frac{d}{t}[/tex]
Item a:
1.5 km in 6 hours, with a velocity of vc - 6, in which vc is the velocity of the canoe and 6 km/h is the velocity of the current, so:
[tex]vc - 6 = \frac{1.5}{6}[/tex]
vc - 36 = 1.5
vc = 37.5.
The canoe should be traveling at a rate of 37.5 km/h.
Item b:
Upstream, the velocity is given by vc - 6, as it is against the stream, hence:
[tex]vc - 6 = \frac{1.5}{2t}[/tex]
[tex]t(vc - 6) = \frac{1.5}{2}[/tex]
[tex]t = \frac{1.5}{2vc - 12}[/tex]
Downstream, we have that:
[tex]vc + 6 = \frac{1.5}{2(\frac{1.5}{2vc - 12})}[/tex]
[tex]vc + 6 = \frac{1.5}{vc - 6}[/tex]
[tex]vc^2 - 36 = 1.5[/tex]
[tex]vc = \sqrt{37.5}[/tex]
vc = 6.124.
The canoe traveled at a rate of 6.124 km/h.

A case of 12 jars of salsa weighs 180 ounces. How many ounces will 5 jars of salsa weigh?
Answers
Answer:
75 ounces
Step-by-step explanation:
Divide 180 by 12 to see how much a single jar weighs
180/12 = 15
Multiply the weight of one jar by how many jars you need
15x5 = 75
Answer: 75 ounces
Step-by-step explanation:
The 12 jars combined weigh 180 ounces in total. We find the weight per jar by dividing 180 ounces by 12 which gives is 15 ounces per jar. We find the weight of 5 jars by multiplying 5 jars by 15 ounces. Here are the calculations as follows.
180÷12=1515x5=75Tina and Rod are married, filing jointly. Their combined taxable income is $65,157. Every week, a total of $158 is withheld from their pay. Based on the table below, how much will Tina and Rod owe when their taxes are due? Show work.

What is the Vertex and Y-intercept of f(x)=3x^2-6x+4? Please show your work.
Answers
Answer:
(1;1) and (0;4)
Step-by-step explanation:
1) if given f(x)=3x²-6x+4 (where a=3; b=-6 and c=4), then
[tex]x_0=\frac{-b}{2a}; \ = > \ x_0=1;[/tex]
[tex]y_0=3*1-6*1+4=1;[/tex]
it means, the vertex has coordinates (1;1).
2) if according to the condition x=0, then
f(0)=0-0+4=4;
it means the Y-intercept is 4.
4) Look at this set of 5 numbers: 5 3 5 3 4
By how much would the mean increase if the number 8 replaced one of the 3's in the
set?
Answers
==========================================================
Explanation:
To compute the mean, we first add up the numbers
5+3+5+3+4 = 20
Then divide by 5 since there are 5 numbers in the set
20/5 = 4
The mean is 4.
---------------
Now replace one of the '3's with 8 and recompute the mean
5+8+5+3+4 = 25
25/5 = 5
The mean is now 5.
The old mean in the previous section was 4.
The mean has increased by 1 since 5-4 = 1.
Side note: The increase from 3 to 8 is +5, which when dividing by 5, we're basically incrementing the mean by +1.
Answer:
1
Step-by-step explanation:
Mean=Sum of terms/ No.of terms
→5+3+5+3+4/5
20/5=4
If we replace 3 as 8 in one of the place values, Then:5+3+5+8+4/5=25/5
→5
Increment= 5-4=1
THUS, 1 is increased.

What is the circumference of a circle with a radius of eight inches
Answers
Answer:
50.24 inches[tex] \: [/tex]
Step-by-step explanation:
It is given that, the radius of a circle is 8 inches and we are to find the circumference of the circle.
[tex] \: [/tex]
To find the circumference of the circle we must know this formula first :
[tex]\\{ \longrightarrow \qquad{ \underline {\boxed{ \pmb{ \mathfrak{ \: Circumference_{(circle)}= 2 \pi r}}}}}} \: \: \bigstar \\ \\[/tex]
Where
r is the radius of the circle.We'll take the value of π as 3.14Now substituting the values in the formula :
[tex]\\{ \longrightarrow \qquad{ {{\sf{{ \: Circumference_{(circle)}= 2 \times 3.14 \times 8}}}}}} \: \: \\ \\[/tex]
[tex]{ \longrightarrow \qquad{ {{\sf{{ \: Circumference_{(circle)}= 3.14 \times 16}}}}}} \: \: \\ \\[/tex]
[tex]{ \longrightarrow \qquad{ { \pmb{\frak{{ \: Circumference_{(circle)}= 50.24}}}}}} \: \: \\ \\[/tex]
Therefore,
The circumference of the circle is 50.24 inchesAnswer:
C = 50.24 in
Step-by-step explanation:
Given that,
→ Radius (r) = 8 in
Formula we use,
→ 2πr
The circumference of the circle will be,
→ 2πr
→ 2 × 3.14 × 8
→ 6.28 × 8
→ [ 50.24 in ]
Hence, the circumference is 50.24 in.
