Answer:
∠BDC=43°
Step-by-step explanation:
Since ABCD is a rectangle, ∠ADC=90
∠ADC=∠BDC+∠ADB
90=(7x+1)+(9x-7)
90=16x-6
16x=96
x=6
∠BDC=7x+1
=7(6)+1
=42+1=43
What is the chance of drawing a card with a heart on a standard deck if I can draw 2 cards?
Answer:
The chances of drawing a heart are therefore 1352 (which reduces to 14 . If we draw another card without replacing the first card, what are the chances of drawing a second heart? There are now 12 hearts in the deck out of 51 cards total and so the odds are 1251 (which reduces to 417 ).
Step-by-step explanation:
So we know that in a 52 card deck, there are 13 hearts, so our probability of drawing a heart on the first try is 13/52.

[tex]6y - 8 + 2[/tex]
simplify by combining like term
so it will end up at 6y-6
you need to combine everything that does not have an exponent (example. a, x, y) and you combine the ones that have exponents together. and therefore you get 6y-6 (remember positive and negative signs)

how many solutions does 6-3x=4-x-3-2x
Answer:
0
Step-by-step explanation:
6 - 3x = 4 - x - 3 - 2x
6 - 3x = -3x + 1
Add 3x to both sides.
6 = 1
Since the last equation, 6 = 1, is false after doing legal steps, that means that the equation is false and has no solution.

4 + 3n = –6 + 4n
Answer: 10
Step-by-step explanation:
Answer:
n=10
Step-by-step explanation:
4+3n=−6+4n
Step 1: Simplify both sides of the equation.
3n+4=4n−6
Step 2: Subtract 4n from both sides.
3n+4−4n=4n−6−4n
−n+4=−6
Step 3: Subtract 4 from both sides.
−n+4−4=−6−4
−n=−10
Step 4: Divide both sides by -1.
n=10
Which step explains how to find the value of a in 6a = 72?
a. add 6 to both sides
b. divide both sides by 6
c. multiply both sides by 6
d. subtract 6 from both sides
Answer:
b divide both sides by 6
Step-by-step explanation:
6a = 72 if you divided each side by 6 you will get
a = 12 which would bring you to the actual answer.
there are 7 days in a week, how many weeks are there in 4,424 days
Answer:
632
Step-by-step explanation:
7 Days are in a week. 4,424 days total, 4,424 divided by 7 would equal 632
Answer:
4424/7=632 so there are 632 weeks.
A biologist must make a medium to grow a type of bacteria. The percentage of salt in the medium is given by S=0.01x^2y^2z , where S is the percentage expressed as a decimal. And where x, y, and z are the amounts in liters of 3 different nutrients mixed together to create the medium. The ideal salt percentage for this type of bacteria is 29.6%. The costs of the x, y, and z nutrient solutions are respectively 9 , 6, and 9 dollars per liter. Determine the minimum cost that can be achieved.

The ratio of the weight of an object on Planet A to the weight of the same object on Planet B is 100 to 3. If an elephant weighs 5000 pounds on Planet A, find the elephant's weight on Planet B.
Answer:
one way to solve this question is to realize that every 100 pounds on planet A equals only 3 pounds on planet B.
So, 5000 pounds divided by 100 = 50. Then that number times 3 will give the weigh on planet B which is 150 pounds.
Algebraically, 100/3 = 5000/x; when we cross multiply, we get 15000/3 = x; x = 150
What is the area of 19 centimeters?
Let's break this up:
Radius: 19
Diameter: 38
Circumference: 119.4
So...
The area of a circle with radius 19 is 1134
A = πr2 = π(d
2
)2 A = C2
4π
π = 3.1415
A = area
C = circumference or perimeter
r = radius, d = diameter
SOLUTION STEPS:
Area of a circle in terms of radius:
Area = π·r2 = 3.14·192 = 1134 square cm(*)
Area of a circle in terms of diameter:
Area = π·(d
2
)2 = 3.14·(38
2
)2 = 3.14·(19)2 = 1134 square cm(*)
Area of a circle in terms of circumference:
Area = C2
4π
= 119.42
4π
= 14256.36
(4·3.14)
= 14256.36
12.56
= 1134 square cm(*)
(*) 1134.1149479459 cm, exactly or limited to the precision of this calculator (13 decimal places).
Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.
Result in other units of area:
A circle of radius = 19 or diameter = 38 or circumference = 119.4 cm has an area of:
1.134 × 10-7 square kilometers (km²)
0.1134 square meters (m²)
1134 square centimeters (cm²)
1.134 × 105 square millimeters (mm²)
4.3784 × 10-8 square miles (mi²)
0.135625 square yards (yd²)
1.22063 square feet (ft²)
175.77 square inches (in²)
