Answer:
height (h) = 15
Step-by-step explanation:
To figure this out, we use the formula 2 · [tex]\frac{A}{a + b}[/tex], where "A" is the area, "a" is one base measure, and "b" is the other base measure.
After plugging in the numbers into the formula, we get 2 · [tex]\frac{390}{23 + 29}[/tex], which equals 15.

Ok my question says "destiny and carla had a total of 3 gallons of paint to share for a project they had 1 gallon each yellow blue and red paint destiny used 3/8 gallon of yellow paint 1/2 of blue paint 1/4 of red paint carla used 1/4 of yellow 3/8 of blue and 1/4 of red then part a ask how much more paint in gallons did destiny use than carly
Answer: 1/4
Step-by-step explanation:
Since Destiny used 3/8 gallon of yellow paint, 1/2 of blue paint and 1/4 of red paint, the total paint used will be:
= ⅜ + ½ + ¼
= 3/8 + 4/8 + 2/8
= 9/8
= 1 1/8
Carla used 1/4 of yellow, 3/8 of blue and 1/4 of red. The total paint used will be:
= 1/4 + 3/8 + 1/4
= 2/8 + 3/8 + 2/8
= 7/8
The numybe of paint that Destiny use more than Carla will be:
= 1 1/8 - 7/8
= 2/8
= 1/4
Destiny used 1/4 paint more than Carla

One interior angle of a triangle is 60'. The other angle measures are x' and y'. Which of the following could be the values of x
and y? Select all that apply.
A x = 50, y = 90
B. * = 100, y = 20
C. x = 45, y = 45
D. X = 40, y = 80
E. x = 60, y = 60
Answer:
B. x = 100, y = 20
D. X = 40, y = 80
E. x = 60, y = 60
Step-by-step explanation:
The sum of interior angles of a triangle = 180°
From the above question, one of the angles = 60°
The value for the two other interior angles = 180° - 60° = 120°
Hence, the following options could be the values of x and y is given as x + y = 120
Therefore,
B. x = 100, y = 20
D. X = 40, y = 80
E. x = 60, y = 60

I need help with question 18. The answer is53√3 ft^2. But how do I get there?
Answer:
Hope it helps....
Step-by-step explanation:
Answer:
52√3 ft²
Step-by-step explanation:
sin 60° = (√3) / 2 = h/8
h = 8 x (√3) / 2 = 4√3
cos 60° = 1/2 = a/8
a = 4 b = 15-4 = 11
area = left triangle + right rectangle
area = (4*4√3) / 2 + 11*4√3
= 8√3 + 44√3
= 52√3
Team A is located on the south bank of a river. Teams B and C are located on the north bank. The angle formed from Team C to Team A is S 20o W. Team C is 45 feet due west of Team B and 25 feet from Team A. How far is Team A from Team B?
Answer:
Step-by-step explanation:
Given :
Using cosine rule :
c² = a² + b² - 2abCosC
c² = 45² + 25² - 2(45)(25) - cos70
c² = 2650 - 2250 * - 0.3420201
c² = 2650 + 769.54532
c² = 3419.5453
c = sqrt(3419.5453)
c = 58.476
c = 58.5 feets
FIND THE SURFACE AREA. I WILL MARK YOU A BRAINLEST IF THE ANSWER IS RIGHT
Answer:
SA= 222cm ^2
Step-by-step explanation:
Surface area of the prism = (Perimeter of the base of the prism) × height + 2(area of the base)
Perimeter of the base = 5 + 3 + 2 + 2 + 2 + 3 + 5 + 8
= 30
Area of the base = 8×5 - 2×2 = 36 cm²
Surface area of the prism = 30×5 + 2×(36)= 222 cm²
Write an equation of the line, in point-slope form, that passes through the points (–7, 2) and (3, –2). Use (–7, 2) as the point (x1, y1)
Answer:
first use the equation m = y2 - y1 / x2- x1 to get the slope
m = -2 - 2 = -4
m = 3 + 7 = 10 when there is a negative for x1 it turns positive
the slope is -4/10 or -2/5
now plus the info into the point slope equation
y - y1 = m (x-x1)
this is in point slope form y - 2 = -2/5 (x + 7)
This is how to get it in y-intercept form
y -2 = -2/5x + -2.8
now add -2 on both sides to the -2.8
y = -2/5x (Slope) + -0.8 y- intercept

⦁ Convert the vertex form of the equation you wrote above to standard form.

Answer:

Step-by-step explanation:
im pretty sure this answers your question
The standard form of the vertex form equation is y = 2x² - 12x + 17
How to convert the equation?The vertex form of a quadratic equation is represented as:
y = a(x - h)² + k
Using the above form, the quadratic equation can be represented as:
y = 2(x - 3)² + 1
Expand
y = 2(x² - 6x + 9) - 1
Further expand
y = 2x² - 12x + 18 - 1
Evaluate the like terms
y = 2x² - 12x + 17
Hence, the standard form of the vertex form equation is y = 2x² - 12x + 17

If CosA= sqrt 3/2, what is TanA?
Answer:
√(3)/3
Step-by-step explanation:
cos(A) = adj./hyp.
adj. = √(3) or √(3)/2
hyp. = 2 or 1
use unit circle:
hyp. = 1
adj. = √(3)/2
use pythagorean theorem c² - b² = a²
1² - (√(3)/2)² = 1 - 0.75 = 0.25
a² = 0.25
a = √(0.25)
a = 0.5
tan(A) = opp./adj.
tan(A) = 0.5/(√(3)/2)
tan(A) = 1/√(3)
rationalize
tan(A) = √(3)/3
Evaluate the expression when a = -3. a^2 +6a +8

Answer:
Rs.12500
Step-by-step explanation:
18% = saved
100 - 18 = 82%(used salary)
82% = 10250
100% = ?
100 × 10250 = 1025000
1025000 ÷ 82 = Rs.12500
A cell phone company expects that every 2 out of 25 cell phones will have some formof defect. At this rate, how many cell phones out of 500 will be expected to have a defect?
Answer: 40 phones
Step-by-step explanation:
The company expects that every 2 out of 25 phones will have some form of defect.
In percentage terms, this is:
= 2 / 25 * 100%
= 8%
If there are 500 phones therefore, the defected phones would still be the same percentage and the actual number would be:
= 8 % * 500
= 40 phones

Answer:
A. (-4, -4)
Step-by-step explanation:
According to the word problem, a dilation of (0.75x, 0.75y) is applied to a triangle.
This means the original coordinates were enlarged/multiplied by 0.75.
We can multiply the coordinates at the bottom by 0.75 to see if we get any of the resulting images' coordinates.
OR
We could divide the resulting images' coordinates by 0.75 to see if we get any of the answers on the bottom.
For instance,
(-3, -3)
-3 / 0.75 = -4 (x-coordinate)
-3 / 0.75 = -4 (y-coordinate)
This means (-4, -4) were the original coordinates of (-3, -3) before the dilation of 0.75.
