Find the area of the following shapes:
Answers
Answer:
Area = 20 square units
Step-by-step explanation:
=> We know that;
Base 1: 3 units
Base 2: 7 units
Height: 4 units
=> Now let's come up with a congruent base first:
[tex]\frac{(3 + 7)}{2}[/tex] = final base
10/2 = final base
5 = final base
=> Finally, Area of the trapezoid:
A = Final Base * Height
A = 5 * 4
A = 20 square units

Answers
Answer:
a
Step-by-step explanation:
[tex]6x+4=20-2x[/tex]
Add 2 to each side
[tex]8x+4=20[/tex]
Subtract 4 from each side
[tex]8x=16[/tex]
Divide 8 by each side
[tex]x=2[/tex]
Answer:
a
Step-by-step explanation:
Your goal is to isolate the variable(x). If you subtract 4 from the left side and right side, then you are left with , 6x=16-2x. Then you add 2x to both sides to get 8x=16. Lastly divide both sides by 8 to get x=2. Hope this helps :)

Sara makes some Blue paint. She mixes yellow, red and brown in the ratio 4: 6: 9. He uses 340 ml of the yellow paint. How much Blue paint does he make?
Answers
Answer:
1615
Step-by-step explanation:
the equation that represents the amount of yellow paint used =
(ratio of yellow paint / sum of ratios) x p = 340
p = blue paint
4 / 19 x p = 340
p = 1615

Writing a linear equations
Answers
Answer:
y = -4x + 5
Step-by-step explanation:
Equation of the line can be written as y = mx + b (slope-intercept form)
Where m = slope and b = y-intercept of the line.
Let's find m and b of the line
Slope (m) using the points (1, 1) and (0, 5),
Slope (m) = change in y/change in x
m = (5 - 1)/(0 - 1) = 4/-1
m = -4
Find b:
b = the point where the line cuts the y-axis = 5 (y-intercept)
To write the equation substitute m = -4 and b = 5 into y = mx + b
y = -4x + 5

Answer:
[tex]\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}[/tex]
Step-by-step explanation:
Given :-
A quadratic equation is given to us.The equation is 2x² + 7x +6=0And we need to find out the roots of the given equation. We can use the middle term splitting method to find out the roots as ,
Given equation :-
[tex]\implies 2x^2 + 7x +6=0[/tex]
Step 1: Find out the factors of 12 :-
We will choose the two factors such that their sum equals to the coefficient of x i.e. 7 .The factors are , 1×12 , 2×6 , 3×4 .
And 3 + 4 = 7. So we will break the middle term into 3x and 4x .Step 2 : Breaking the middle term :-
[tex]\implies 2x^2 + 3x+4x +6=0[/tex]
Step 3: Take out common from terms :-
[tex]\implies x(2x + 3) +2(2x +3)=0[/tex]
[tex]\implies ( x +2)(2x+3)=0 [/tex]
Step 4 : Equate them with 0 :-
[tex]\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}[/tex]
Hence the correct options are C and D .

In the 2004 Summer Olympics, Adam van Koeverden of Oakville, Ontario, won two medals. He won the gold medal in the men’s 500 m kayak race, with a time of 1 min 37.9 s. He also won the bronze medal in the 1000 m race, with a time of 3 min 28.2 s. In which race did he row with greater speed?
Answers
Answer: 500 meters
Step-by-step explanation:
Since he won the gold medal in the men’s 500 m kayak race, with a time of 1 min 37.9 s, the speed will be:
= Distance/Time
= 500m/1 min 37.9s
= 500m/97.9s
= 5.11m/s
Since he also won the bronze medal in the 1000 m race, with a time of 3 min 28.2s, the speed will be:
= Distance/Time
= 1000/3 min 28.2s
= 1000m/208.2s
= 4.80m/s
Therefore, he rowed with greater speed in the 500 meters.
Note that 60seconds = 1 minute

Step-by-step explanation:
4x=12
divide both sides by 4

x/-3 = 1
multiply both sides by -3
x/-3 (-3) = 1 (-3)
simplify both sides
x = -3
what is the missing exponent?
17 / 17^4 = 17^8
Answers
Answer:
The missing exponent is 12.
Step-by-step explanation:
Whenever you divide same-base exponents, you keep the base numbers the same and subtract the exponents.
The only number subtracted by 4 that would give you 8 is 12.
Or, if the numbers are larger, it is must easier to add the exponent in the answer to the number in the equation.
For example,
[tex]17^4+17^8=17^1^2[/tex]
Therefore, the missing exponent is 12.
Because: [tex]17^1^2/17^4=17^8[/tex]

10. C= 5
11. B= 2 V55 (2 square root of 55)
12. C= 2 V5
13. A= V5.39
Explanation:
10. a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2 (add 9 and 16)
25=c^2
V25= Vc^2 (take the square root of both sides to get):
5=c
11. 6^2+b^2=16^2
36+b^2=256 (256-36)
b^2=220 (square root, 220 cannot be simplified so you factor it and get):
b= 2 V55
12. 4^2+2^2=c^2
16+4=c^2
20=c^2 ( square root it then factor)
2 V5 = c
13. a^2+3.5^2=4.2^2
a^2+12.25=17.64 (subtract 17.64 and 12.25)
a^2=5.39 ( square root/ cannot be simplified so the square root of 5.39 is your answer)

Step-by-step explanation
A business owner wants to have the front window of her store painted and is considering two
artists for the job. Tiana has quoted a flat rate of $292 for the job. Denise's quote is $39 per
hour, plus $19 to cover the cost of materials. Depending on how long it takes Denise to paint
the window, these two could end up charging the same amount. How long would Denise have
to take? How much would it cost?
Answers
to get the answer:
i subtracted $19 from $292 to eliminate the
fee element because if you were to divide
$292 by $39 without the step, the hours would be incorrect and the price would be greater.
after subtracting i got $273
from there i divided $273 by $39 and got 7 (the amount of hours it would take)
Write the equation of the circle with center (0, 0) and (3, 6) a point on the circle.
Answers
Answer:
Step-by-step explanation:
We will use the standard form of a circle to solve for the radius and then fill it back in. h is 0, k is 0, x is 3, and y is 6:
[tex](3-0)^2+(6-0)^2=r^2[/tex] and
[tex]3^2+6^2=r^2[/tex] and
[tex]9+36=r^2[/tex]
Therefore, r-squared is 45, so the circle's equation in standard form is
[tex](x-0)^2+(y-0)^2=45[/tex] or more simply:
[tex]x^2+y^2=45[/tex]
