Answer:
114
Step-by-step explanation:
We know that [tex]f(x) = 4x^2-7x+12[/tex] and that [tex]f(x) = f(6)[/tex]. Therefore, you substitute x as 6 in the given expression.
Calculations:
[tex]f(x) = 4x^2-7x+12[/tex]
[tex]f(6)=4(6)^2-7(6)+12[/tex]
[tex]4(36)-42+12=114[/tex]

Please help.. Answer number 34 and 35. For number 34 find the measures of the numbered angles in each isosceles trapezoid. For number 35 find the measures of the numbered angles in each kite.
Answers
Answer:
33. m∠1 = 135°, ∠3 = 45°, ∠2 = 135°
34. m∠1 = 80°, m∠2 = 100°, m∠3 = 100°
35. m∠1 = 90°, m∠2 = 25°
Step-by-step explanation:
33. The given parameters of the isosceles trapezoid are;
The measure of one of the base angles = 45°
For an isosceles trapezoid, the base angles are equal, therefore, we have;
The measure of the other base angle = m∠3 = 45°
Similarly, m∠1 = m∠2
Also, we have;
The sum of the interior angles in a trapezoid = The sum of the interior angles in a quadrilateral = 360°
∴ 45° + m∠3 + m∠1 + m∠2 = 360°
By substituting the known values, we have;
45° + 45° + m∠1 + m∠2 = 360°
From m∠1 = m∠2, we have;
45° + 45° + m∠1 + m∠1 = 90° + 2·m∠1 = 360°
2·m∠1 = 360° - 90° = 270°
∴ m∠1 = 270°/2 = 135°
m∠1 = 135° = m∠2
Therefore, we have;
∠3 = 45°, ∠1 = 135°, ∠2 = 135°
34. The measure of the base angles = 80°
∴ The measure of the other base angle = m∠1 = 80°
m∠2 = m∠3
80° + m∠1 + m∠2 + m∠3 = 360°
∴ 80° + 80° + 2·m∠2 = 360°
m∠2 = (360° - (80° + 80°))/2 = 100°
m∠2 = 100° = m∠3
35. The kite comprises of two half isosceles triangles
The base angles of the right half isosceles triangle = 65°
The angle formed by the diagonals of the kite = 90° (Perpendicular diagonals theorem)
Therefore, m∠1 = 90°
The diagonals bisect the angles at the vertices (Kite theorem)
Therefore, we have;
65° + 90° + m∠2 = 180°
m∠2 = 180° - (65° + 90°) = 25°
m∠2 = 25°.

What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
An inverse variation includes the points (15, 1) and (n, 5).
Now, We know that;
The inverse variation is defined as,
⇒ y = k x
Here, An inverse variation includes the points (15, 1) and (n, 5).
Hence, Substitute x = 15, and y = 1;
⇒ 1 = k × 15
⇒ k = 1/15
And, Substitute x = n and y = 5;
⇒ y = k x
⇒ 5 = 1/15 × n
⇒ 5 × 15 = n
⇒ n = 75

The sum of three number is 35.
What is Square?A square number is the result when a number has been multiplied by itself.
For example, 25 is a square number because it's 5 lots of 5, or 5 x 5.
Given:
if the number given is 9
9² - (9 - 1)² = 9² - 8²
= 81-64
= 17.
if the number given is 6.
6² - (6 - 1)² = 6² - 5²
= 36-25
= 11.
if the number given is 4.
4² - (4 - 1)²= 4² - 3²
= 16-9
= 7.
Thus, the sum of three number is
=17 + 11 + 7
= 35

Emily has 59 flowers. She wants to put the flowers in 6 vases with the same number in each vase. Part A: What is the greatest number of flowers she can put in each vase? Part B: How many flowers will Emily have left over?
Answers
Answer:
Part A
= 9 flowers
Part B
= 5 flowers
Step-by-step explanation:
Emily has 59 flowers. She wants to put the flowers in 6 vases with the same number in each vase.
Part A: What is the greatest number of flowers she can put in each vase?
This is calculated as:
59 flowers ÷ 6 vases
= 9 5/6 flowers
Therefore, the greatest number of flowers she can put in each vase is 9 flowers
Part B: How many flowers will Emily have left over?
We have to calculate the number of flowers in the 6 vases above
= 9 flower × 6
= 54 flowers
Hence:
= 59 flowers - 54 flowers
= 5 flowers
Therefore, Emily would have 5 flowers left over.

The Johnson and Sloan families went to Taco Mania for lunch. The Johnsons bought 3 burrito meals and 4 taco meals for $48. The Sloans bought 6 burrito meals and 2 taco meals for $60. How much does each meal cost?
Answers
Answer:
Each burrito meal cost 8$
Each taco meal cost 6$
Step-by-step explanation:
Johnsons= 3b +4t =48
Sloans= 6b+2t=60
multiple johnsons by -2
so, now the johnsons are -6b+-8t=-96
add that to the sloans so, -6b+6b-8t+2t=-96+60
the b's cancel eachother out, so you are left with -6t= -36
divide each side by -6 and you will get t=6
then you can pick either formula, lets say sloans this time
so, 6b + 2(6)=60 so, 6b+12=60, subtract 12 from each side, to get 48
so 6b=48, divde each side by 6 and you will get b=8
Step-by-step explanation:
Answer:
Tacos-6
Burritos-8
Step-by-step explanation:
Multiply the first equation by -2,and multiply the second equation by 1.
−2(3b+4t=48)
1(6b+2t=60)
Becomes:
−6b−8t=−96
6b+2t=60
Add these equations to eliminate b:
−6t=−36
Then solve−6t=−36for t:
−6t=−36
−6t
−6
=
−36
−6
(Divide both sides by -6)
t=6
Now that we've found t let's plug it back in to solve for b.
Write down an original equation:
3b+4t=48
Substitute6fortin3b+4t=48:
3b+(4)(6)=48
3b+24=48(Simplify both sides of the equation)
3b+24+−24=48+−24(Add -24 to both sides)
3b=24
3b
3
=
24
3
(Divide both sides by 3)

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 675 square feet. The width of the basement is 1/3
its length. What is the length of Louis's basement?
Answers
I am reading this correctly, the width = 1/3 of the length?
If this is the case, and we know that the area is 675, the equation is as follows.
Width x Length = 675 ft2
X = length
1/3 X x X = 675 ft2
To solve for X we have to multiply both sides by 3.
X square 2 = 2601 square feet.
Take the square of each side.
X = 225 sqare feet.

Trista types at the same rate as the average person and made the double number line below to estimate how long it will take her to type her research paper. Using Trista's double number line, estimate how long it will take her to type her 1,400-word research paper.
Answers
Answer:
35 minutes
Step-by-step explanation:
Given that:
Trista:
Average word type per hour = 2400 words /hr
For Trista to type her 1400 word research paper ;
It will take 'h' hour
If
2400 words = 1 hour
1400 words = h
Cross multiply :
2400h = 1400
h = 1400 / 2400
h = 0.5833333 hr
To minutes, it will take :
0.5833333 * 60 = 35 minutes
Hence, it will take Trista 35 minutes or 0.5833333 to type her 1400 words research paper.
