Answer:
-3
Step-by-step explanation:
The fastest way to solve this problem is to multiply each side of the given equation by in order to get rid of the fraction. After you do this you should have:
Then multiply [tex](-8x-3)[/tex] and [tex](ax-2)[/tex] using FOIL:
[tex]24^2+25x-47=-8ax^2-3ax+16x+6-53[/tex]
Then reduce on the right side of the equation:
[tex]24x^2+25x-47=-8ax^2-3ax+16x-47[/tex]
Because the coefficients of the [tex]x^2[/tex] term have to be equal on both sides of the equation, reduce from [tex]-8a=24[/tex] to [tex]a = -3[/tex] by dividing both sides by [tex]-8[/tex].
A kangaroo hopped 3{,}5203,5203, comma, 520 yards to the lake with her baby in her pouch. She hopped the remaining 5{,}2805,2805, comma, 280 yards without her baby in her pouch. How many miles did the kangaroo hop to the lake? Miles
Answer:
5 miles
Step-by-step explanation:
Here is a more clear question :
A kangaroo hopped 3,520 yards to the lake with her baby in her pouch. She hopped the remaining 5,280 yards without her baby in her pouch. How many miles did the kangaroo hop to the lake? Miles
to determine the answer
1. add the yards hopped with the baby with the yards hopped without the baby together
3520+5280=8800 yards
2. convert yards to miles
1 yards = 0.000568182 miles
0.000568182 x 8800 = 5 miles

x² + 2.75² = 15.25²x² = 15.25² - 2.75²x² = 225x = √225x = 15Step-by-step explanation:
Perpendicular=p=2.75Hypotenuse=h=15.25we know that
[tex] \boxed{ \sf \: h {}^{2} = {p}^{2} + {b}^{2} } \\ \rm \mapsto \: {(15.25)}^{2} = {(2.75)}^{2} + {b}^{2} \\ \rm \mapsto \: {b} {}^{2} = {(15.75)}^{2} - {(2.75)}^{2} \\ \rm \mapsto \: b = \sqrt{ {(15.25)}^{2} - {(2.75)}^{2} } \\ \rm \mapsto \: b = \sqrt{232.5 - 7.5} \\ \rm \mapsto \: b = \sqrt{225.5} = 15.07=15(approx)[/tex]

1. what is f(3)?
2. what is f(-2)?
3. find g(10).
4. given g(x) = 17, find x.
Answer:
14, 19, 26, 7
Step-by-step explanation:
f(3) = 2(3)^2 - 3(3) + 5
f(3) = 2(9) - 9 + 5
f(3) = 18-9+5
f(3) = 14
f(-2) = 2(-2)^2 - 3(-2) + 5
f(-2) = 2(4) + 6 + 5
f(-2) = 8 + 6 + 5
f(-2) = 19
g(10) = 3(10) - 4
g(10) = 30-4
g(10) = 26
17 = 3x-4
21 = 3x
7 = x

What is the volume of this container?
A.4,000 cm^3
B.6,000 cm^3
C.900 cm^3
D.3,000 cm^3
Answer:
6000 cm³
Step-by-step explanation:
Here, we have 2 cuboids. What we do is add the area of both together.
Area of a cuboid is l * b * h
Cuboid A, area = 20 * 15 * 10 = 3000
Cuboid B, area = 20 * 15 * 10 = 3000
3000 + 3000 = 6000

1.Construct or draw an isosceles triangle with one angle measure of 70 degrees. Label all of the angle measures.
Answer:
See images
Step-by-step explanation:
Either one should work.
An isosceles triangle is a triangle where two angles are the same & the third angle is the supplement of their sum.
If you wanted the matching angles to be 70 & 70, your final angle would be 40 because:
70 + 70 = 140
180 - 140 = 40
If you wanted the supplement angle to be 70, your matching angles would be 55 & 55 because:
180 - 70 = 110
110 / 2 = 55
Hope this helped. :)
Stephan has a piece of wood that measures 18 inches long and 12 inches wide. He wants to make a tray with sides 2 inches high. Maurice says that he can make a tray that has a base measuring 10 1/2 inches by 10 1/2 inches. Is he correct? Use the drop-down menus to explain your answer.
Answer:
i. No, Maurice statement is wrong.
ii. Stephan does not have sufficient pieces of wood to make the tray because the square inches required is more than what he has.
Step-by-step explanation:
Stephan's piece of wood measures; 18 inches in length and 12 inches in width.
Since the piece of wood has a shape of a rectangle,
the area of the piece of wood = length × width
= 18 × 12
= 216 square inches
According to Maurice's statement, he could make a tray that has a base of 1012 inches by 1012 inches.
The base has the shape of a square, so that;
the area of the base = length × width =
= 1012 ×1012
= 1024144 squared inches
This shows that Stephan does not have sufficient wood to make the tray because the square inches required is more than what he has. and 16 more users found this answer helpful

h(x)=1x-21, find h(-10)
Answer:
h(-10) = -31
Step-by-step explanation:
Substitute -10 for x in h(x)=1x-21:
h(-10) = 1(-10) - 21, or
h(-10) = -10 - 21 = -31
h(-10) = -31

Find the principal. SHOW ALL WORK to receive FULL CREDIT.
I=P∙r∙t
Interest earned: $45
Principal: ?
Interest rate: 3%
Time: 5 months
Answer:
300
Step-by-step explanation:
I = interest earned
P = Principal
R = interest rate
T = Months
plug in all the numbers which would be...
45 = P x 0.03 x 5 *Note that 0.03 is 3% in decimal form
0.03 x 5 = 0.15
45 = P x 0.15
to make the P by itself you have to divide 0.15 to both sides
45/0.15 = 300
P = 300

Answers:
a = 7b = 14c = 7d = 7*sqrt(3)======================================================
Explanation:
The smaller triangle on the left is a 45-45-90 triangle. In these triangles, the hypotenuse is sqrt(2) times that of the leg length.
The hypotenuse shown is 7*sqrt(2), so that must mean each leg is 7 units long. Therefore, a = c = 7.
The triangle on the right is a 30-60-90 triangle. The shorter leg (opposite the smallest angle of 30 degrees) doubles to get the hypotenuse. So we can say b = 2a = 2*7 = 14. The longer leg is exactly sqrt(3) times that of the shorter leg. The longer leg is d = a*sqrt(3) = 7*sqrt(3)
y=5x−2 into polar form
Answer:
r·sin Ф = 5(r·cos Ф) - 2
Step-by-step explanation:
y = r·sin Ф and x = r·cos Ф, and so
y = 5x - 2 becomes
r·sin Ф = 5(r·cos Ф) - 2
Answer:
rsin(0) = 5rcos (0) - 2
Step-by-step explanation:
Convert y = 5x - 2 to polar coordinates.
To convert to polar apply: x = r · cos (0), y = r · sin (0)
Find the slope of the line through the points (-4, 3) and (3, 5)
Answer: 2/7
Step-by-step explanation:
Slope is ∆y/∆x. ∆ is read as "delta". The "delta" sign means "the difference between". So that means the difference between the y-coordinates divided by the x-coordinates gives us slope. Therefore, using the coordinates, 5-3 gives us the rise. And 3-(-4) gives us the run. Rise/Run is also equivalent to the slope. Thus, our final answer is 2/7.

If x=|9| what are the possible value of x
The requreid if x = |9|, then x could only have one possible value, which is x = 9
The absolute value of a number is its distance from zero on the number line. When pointing to the absolute value of a positive number, the result is the same number.
The absolute value of 9 is 9 since 9 is already a positive number.
The absolute value of 9 is 9. Therefore, if x = |9|, then x could only have one possible value, which is x = 9
So the only possible value of x is 9.
