The measure of ∠BCD is 145°. The measure of ∠ABC is 65°.
What is measure of ∠BAC?
115°
35°
80°
145°
Answer:
m∠BAC = 80°Step-by-step explanation:
m∠BCD = 145° ⇒ m∠BCA = 180° - 145° = 35°
From ΔABC:
m∠ABC + m∠BCA + m∠BAC = 180°
65° + 35° + m∠BAC = 180°
m∠BAC = 180° - 100°
m∠BAC = 80°
Kris thinks of a number. He divides by 14, subtracts 5. The number is the same as he thought of. What’s the number?
Answer:
0
Step-by-step explanation:
If you divide 14 by 0 it will be 0, and you subtract by 5 it will still be 0.
the sides of a triangle are 5:8:10 and it's perimeter is 23 cm. find the area of triangle.
Answer:
19.81cm^2
Step-by-step explanation:
To solve this, you need to use Heron's formula. Heron's formula solves for the area of a triangle given 3 sides defined as a, b, and c, as well as the perimeter. In this formula, p is half of the perimeter. The formula is:
sqrt(p*(p-a)*(p-b)*(p-c))
Plugging the values into this formula gives 19.81cm^2.

The circumference of a round pillow is 46.8 centimeters. Find the radius of the pillow, in centimeters. Round your
answer to the nearest tenth.
Answer:
7.5 centimeters
Step-by-step explanation:
The circumference is pi times the diameter
46.8/3.14=14.9
The radius is half of the diameter
14.9/2=7.45
7.45 is rounded to 7.5
Candice wrote the four equations below. She examined them, without solving them, to determine which equation has an infinite number of solutions.
Negative 5 x + 1 = negative 5 x + 1. Negative 2 x + 1 = negative 2 x + 2. 3 x + 5 = 3 x minus 5. 4 x minus 2 = x + 1.
Which of Candice’s equations has an infinite number of solutions?
Negative 5 x + 1 = negative 5 x + 1
Negative 2 x + 1 = negative 2 x + 2
3 x + 5 = 3 x minus 5
4 x minus 2 = x + 1

− 14 n + q = r t − 4 n , for n
Answer:
n = q/10 - (r t)/10
Step-by-step explanation:
Solve for n:
q - 14 n = r t - 4 n
Subtract q - 4 n from both sides:
-10 n = r t - q
Divide both sides by -10:
Answer: n = q/10 - (r t)/10

How can the graph look like?
Pls help
Answer: OK, stay with me on this one
the image is what your graph will look like, but with 2 lines instead of one. on the bottom, mark the months. on the side, write temperatures. Then on each month for the line for A, dot the temperature it is with a connected line. (Like the line is on the image.) Then do the same for the line for city B. I'd recommend doing it in 2 different colors, and label some where else which city.

Based on the measurements shown on triangle ABC, AB must be?
Answer: B. 7 and 10 ft
Step-by-step explanation:
The first thing to do is to look at the triangle’s angles. One of them is missing right? So you need to find that missing angle. All the angles in a triangle add up to 180 degrees. Therefore you need to add 68 and 47. Your total must be subtracted by 180.
Your problem will look like this
68+47=115
180-115=65
Your missing angle is 65The angle correspond to the sides. You need to look at the opposite of the angle to figure out the number of the side.
For example Angle A opposite = 7
Angle B opposite is 10
notice that Angle B degree is 68 which is the largest degree. And Angle A degree is 47 which is the smallest degree.
The largest degree will always be equal to the largest side
The smallest degree will equal to the smallest side
- Please help this is a Rational Inequality problem
1. A ball is thrown straight up from the top of a building that is 400 ft high with an initial velocity of 64 ft/s. The height of the object can be modeled by the equation s(t) = -16t^2 + 64t + 400. (solve step by step pls)
2. In two or more complete sentences explain how to determine the time(s) the ball is higher than the building in interval notation.
The interval for the given situation is (0, 4).
Given that, height = 400 ft, initial velocity of 64 ft/s and the equation s(t) = -16t² + 64t + 400.
What is an initial velocity?Initial velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts. They are four initial velocity formulas: (1) If time, acceleration and final velocity are provided, the initial velocity is articulated as. u = v – at.
To find the interval in which the ball is higher than the building, solve the inequality h(t) > 400. The inequality is easily solved by subtracting 400 so the comparison is to zero, factoring the expression involving t, and identifying the time interval in which the signs of the factors are the same.
-16t² +64t +400 > 400
⇒ -16t² +64t > 0
⇒ -16t (t -4) > 0
⇒ t=0 and t-4=0
Both factors will have negative signs on the interval (0, 4).
Therefore, the interval for the given situation is (0, 4).

The scatterplot illustrates the relationship between two quantitative variables: the number of seeds planted per square foot and the yield of the crop (in pounds per square foot).
A graph titled Number of Seeds and Crop Yield has seeds (per square foot) on the x-axis, and yard (pounds per square foot) on the y-axis. The points curve up to a point, and then curve back down.
Which of the following is an accurate description of the scatterplot?
Answer:
I cannot confirm answer (D), but it looks correct to me.
Here's the option:
The expected yield of a crop is low whenever the number of seeds planted per square foot is small or large. A larger yield is expected when the number of seeds per square foot is around 60.

Answer:
B
Step-by-step explanation:
2(X+4)=6x+7-4x+1
2x+8=6x+7-4x+1
2x+8=6x-4x+7+1
2x+8=2x+8

Answer:
B
Step-by-step explanation:
2(x + 4) = 6x + 7 - 4x + 1 ← distribute parenthesis on left side
2x + 8 = 2x + 8
since both sides of the equation are the same then any real value of x will be a solution to the equation, that is
the equation has infinitely many solutions
how to tell if a graph is a function?
Answer:
If you take a vertical line and place it on the graph, then no matter where on the graph you place the vertical line, the graph should only cross the vertical line once. If so, then it is a vertical line.
If not, then it isn't one.

Correctly multiply (3x + 7) (7x + 5)
Then find the sum of the coefficients of your solution.
Answer:
The sum of the coefficients is 85.
Step-by-step explanation:
(3x + 7)(7x + 5)
3x * 7x is 21x^2
3x*5 is 15x
7 * 7x is 49x
7 * 5 is 35
21x^2 + 15x + 49x + 35
So the answer is 21x^2 + 64x + 35
Add the coefficients: 21 + 64 = 85
