Answer:
15 = t
Step-by-step explanation:
3 = t - 12
3 + 12 = t
15 = t
Answer:
C:15 if were going off t
Step-by-step explanation:
if you switch around the equation a bit you get t-12=3 now what number minus 12 equals three thats what your trying to find so the only logical answer is C because 15-12=3 so t=15

What is the height (h) of the sign? Leave your answer in simplest radical form.
Answer:
18[tex]\sqrt{3}[/tex] inches
Step-by-step explanation:
Applying,
Pythagoras theorem,
a²= b²+c²
Where a = hypotenus, b = base of the triangle, c = height.
make c the subject of the equation
c = √(a²-b²)................. Equation 2
From the diagram attached,
Given: a = 36 in, b = (36/2) in = 18 in
Substitute these values into equation 2
c = √(36²-18²)
c = √(1296-324)
c = √(972)
c = √(972)
c = √(324×3)
c = 18[tex]\sqrt{3}[/tex] inches

There are 2.54 Centimeters in 1 inch . THere are 100 Centimeters in 1 meter
To the nearest Meter, how many meters are in 360 inches
Answer:
9.144meters
Step-by-step explanation:
Given data
We are expected to perform unit conversion in this problem
2.54cm is equivalent to 1 inch
100cm equal to 1 meters
360 inches to cm will be
=360*2.54
= 914.4cm
914.4cm to meters will be
=914.4/100
=9.144meters

Describe the relationship between GF and CD when the two lines are perpendicular to AB. Also describe the relationship between GF and CD when CD is not perpendicular to AB . Zoom in or out on the coordinate plane, if needed.
Answer:
See Explanation
Step-by-step explanation:
Given
Lines GF, CD and AB
Required
Relationship between GF and CD
The question is incomplete, as there is no attachment to support the given parameters.
The general solution goes thus:
(a) CD and GF perpendicular to AB
If two lines are perpendicular to another line; then the two lines are parallel to each other.
This means that CD and GF are parallel, and they have the same slope
(b) CD is not perpendicular to AB
Here, we know that GF is perpendicular to AB, CD is not;
This means that GF and AB are not parallel.
More information is needed to determine the actual relationship between GF and AB; but for sure, they are not parallel.

84
Answer:
84
Step-by-step explanation:
Step 1: Convert number to a fraction
[tex]24=\frac{24}{1}[/tex]
[tex]\frac{1}{2}\times \frac{24}{1}\times \:7[/tex]
Step 2: Factor the number
[tex]\:24=2\times \:12[/tex]
[tex]\frac{2\times \:12}{2}\times \:7[/tex]
Step 3: Cancel the common factor
[tex]2[/tex]
Step 4: Multiply the remaining numbers
[tex]12\times \:7\\\\= 84[/tex]
Therefore, [tex]\frac{1}{2}\times 7\times 24\:=\:84[/tex]

Fine the scale factor of the dilation.
Answer:
either 2 or 1/2, depending on what the original shape was
Step-by-step explanation:
going from small to large it is clearly visible that 3 units of side length turn into 6 units. so, the scaling factor is 2.
going from large to small it is clear that 6 units of side length turn into 3 units. so, the scaling factor is 1/2.
If a circle has a radius of 16, and an arc length of 12, what is the angle measure of the central angle that matches that arc?
Answer:
135°
Step-by-step explanation:
The arc length is calculated as
EF = circumference of circle × fraction of circle
= 2πr × [tex]\frac{?}{360}[/tex]
Given EF = 12π , then
2π × 16 × [tex]\frac{?}{360}[/tex] = 12π ( divide both sides by 2π )
16 × [tex]\frac{?}{360}[/tex] = 6 ( multiply both sides by 360 to clear the fraction )
16 ? = 2160 ( divide both sides by 16 )
? = 135°

Omar compra una bicicleta, que tiene un descuento del 75%. Si el precio que pago es de Q 70.00. ¿Cuál fue el precio original?
Answer: Por ejemplo, un televisor podría costarle originalmente $ 5000. Determine el porcentaje de descuento: en nuestra tienda de ejemplo, todo tiene un 75% de descuento. La suma que queda en su bolsillo, sus ahorros, es simplemente estos dos valores multiplicados entre sí: 75% * $ 5000 = 0,75 * $ 5000 = $ 3750.
The bacteria population in a petri dish was 14 at the beginning of an experiment. After 30 minutes the population of 20 in after an hour the population of 56
Answer:
The answer is below
Step-by-step explanation:
A geometric sequence is a sequence such that each term after the first is found by multiplying the previous one by a fixed number (common ratio). It is given by:
[tex]a_n=ar^{n-1}\\\\n=1,2,3,\ .\ .\ .[/tex]
where a is the first term, r is the common ratio.
From the question, the first term is 14 (at n = 1). a₁ = 14
After 30 minutes (n = 2), the population is 28. a₂ = 28
After 1 hour (n = 3), the population is 56. a₃ = 56
Common ratio (r) = a₃/a₂ = a₂/a₁ = 56 / 28 = 28/14 = 2
a) This sequence is represented as:
[tex]a_n=14(2)^{n-1}[/tex]
b) After 4 hours, that is n = 9:
[tex]a_9=14(2)^{9-1}=14(2)^8=3584[/tex]
convert 374F in base 16 to octal
33517
Step-by-step explanation:Method 1
Given:
374F in base 16
To convert to octal;
(i) convert each digit in the number to binary
3 = 0011
7 = 0111
4 = 0100
F = 1111
(ii) join the bits together starting from the first i.e
374F = 0011 0111 0100 1111
(iii) starting from the right to left, group the bits together, each group having 3 bits
374F = 0 011 011 101 001 111
(iv) the group with number of bits less than 3 should be padded with zero.
374F = 000 011 011 101 001 111
(v) convert each of the groups in (iv) above to decimal as follows:
000 = 0
011 = 3
011 = 3
101 = 5
001 = 1
111 = 7
(vi) combine the result above to get;
033517
The first zero can be removed
33517
Therefore, the number in octal is 33517₈
Method 2
Given:
374F in base 16
To convert to octal;
i) convert the number to decimal as follows;
a. Multiply each digit by 16 raised to the power of one less than their position starting from the leftmost digit.
=> 3 is at position 4, so we have
3 x 16⁴ ⁻ ¹ = 3 x 16³
=> 7 is at position 3, so we have
7 x 16³ ⁻ ¹ = 7 x 16²
=> 4 is at position 2, so we have
4 x 16² ⁻ ¹ = 4 x 16¹
=> F is at position 1, so we have
F x 16¹ ⁻ ¹ = F x 16⁰
b. Add each of the terms found in (a) together.
(3 x 16³) + (7 x 16²) + (4 x 16¹) + (F x 16⁰)
c. Remember that F = 15 in decimal. Therefore, substitute F = 15 into the result in (b)
(3 x 16³) + (7 x 16²) + (4 x 16¹) + (15 x 16⁰)
d. Solve the result in (c)
(3 x 4096) + (7 x 256) + (4 x 16) + (15 x 1)
12288 + 1792 +64 + 15
14159
Therefore,
374F in decimal is 14159
(b) Now convert the decimal to octal by dividing by 8 and noting the remainder.
8 | 14159
8 | 1769 r 7
8 | 221 r 1
8 | 27 r 5
8 | 3 r 3
| 0 r 3
Taking the remainders from bottom up gives
33517₈
Therefore, the number in octal is 33517₈

Answer:
y=2(x + 2))^2 - 9
Step-by-step explanation:
So, whenever two negative signs are right next to each other, they make a positive. However, when they are alone, they stay negative.
With this, y=2(x-(-2))^2 + (-9) --> y=2(x + 2))^2 -9

Answer:
25.5 = c
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
17^2 + 19 ^2 = c^2
289+361 = c^2
650 = c^2
Take the square root of each side
sqrt(650) = sqrt(c^2)
25.49509757=c
To the nearest tenth
25.5 = c
Answer:
C = 25.5
Step-by-step explanation:
17² + 19² = x²
289 + 361 = x
289 + 361 = 650
√650 = 25.495097567963924150141120545114
25.495097567963924150141120545114 ≅ 25.5
