what kind of triangle is bcd
Answer:
C. obtuse
Step-by-step explanation:
Obstuse is a triangle with ONE angle bigger than 90 degrees.
The triangle ΔBCD will be an acute triangle. Then the correct option is B.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The measure of the angle BCD is 70°. And the exterior angle of the angle BDC is 130°. The sum of the interior and exterior angles is 180°. Then the measure of the angle BDC will be
∠BDC + 130° = 180°
∠BDC = 50°
Then the measure of angle CBD will be given as,
∠CBD + ∠BDC + ∠DCB = 180°
∠CBD + 70° + 50° = 180°
∠CBD = 60°
The measure of all the angles of the triangle is less than 90°. Then the triangle ΔBCD will be an acute triangle. Then the correct option is B.

Rhonda has a bag of 9 servings of trail mix that weighs 1,350 grams. The bag has 6,237
calories. If she eats 2 servings of trail mix, how many calories does she eat?
1,387 calories
350 calories
693 calories
1,386 calories
Answer:
1,386 calories
Step-by-step explanation:
The 1,350 is not important- this is just the weight of the bag.This is a ratio problem, so we need to compare 9 and 6,237 to 2 and _.9/2 = 4.5, so you would divide 6237/4.5. This is 1386 calories- the answer.magine you have two friends, Jose and Jessie. Jose is a gifted athlete, but Jessie lives a sedentary lifestyle. Jose and Jessie both ask you to develop an action plan to improve their flexibility. How would your advice differ for Jose and Jessie? Consider specific exercises, frequency of exercise, level of conditioning, levels of flexibility, goal setting, and other important factors in your response.
Answer:
First of all, Jose and Jessie have a big difference when it comes to physical health and condition. Jessie is not able to perform the same exercises as Jose, neither the same intensity, and they cannot have the same goal.
So, for Jessie improve her flexibility we have to consider low intensity exercises, specifically, aerobic exercises, like walking, dancing, jogging at a low pace, pilates and yoga. Jessie, as a sedentary person most consider to do those aerobic activities three times per week, at least 30 minutes to ensure that she is demanding enough effort from her body, but all at low intensity.

Answer:
[tex]r\approx 162~units[/tex]
Step-by-step explanation:
The Circumference of a Circle
The circumference is the arc length of the circle.
A circle with radius r has a circumference calculated by:
[tex]C=2\pi\cdot r[/tex]
If we are given the circumference, the radius can be calculated by solving the equation for r:
[tex]\displaystyle r=\frac{C}{2\pi}[/tex]
The circumference of the circle is 1,017.36 units. Calculating the radius:
[tex]\displaystyle r=\frac{1,017.36}{2\pi}[/tex]

Answer:
Irregular polygons are polygons that do not have equal sides or equal angles. When finding the area of an irregular polygon, partition the polygon into smaller regular polygon shapes. You can then plug those measurements into their respective area formulas and multiply to find the area of one part of the shape.
This is 16cm.
Carpect costs $16 a square foot. A rectangular floor is 16 feet long by 14 feet wide. How much would it cost to carpet the floor?
Answer:
$3584
Step-by-step explanation:
- because its a rectangle, the area of the floor is length*width, so 16*14 = 224 square feet
- one square foot is $16, so 224 sqaure feet are 224*16
= 3584
Answer:
$3584
Step-by-step explanation:
To find square feet, multiply the length measurement in feet by the width measurement in feet.
16 x 14 = 224
Now, find how much it costs, there is 224 square feet in total so since it's 16 dollar for every square feet.
224 x 16 = 3584

2x + 3y = 2
a.) 4
b.) −2
c.) x can be any number as there are infinitely many solutions to this system
d.) There is no x value as there is no solution to this system.
Please and thank you!!
Answer:
x = 4
Step-by-step explanation:
To find x, we can use elimination:
[tex]3(3x+2y)=3\times8[/tex] (times 3 on both sides so [tex]2y[/tex] becomes 6y)
[tex]9x+6y=24[/tex]
[tex]2(2x+3y)=2\times2[/tex] (times 2 on both sides so [tex]3y[/tex] becomes 6y)
[tex]4x+6y=4[/tex]
[tex]9x+6y-(4x+6y)=24-4[/tex] (This eliminates the variable [tex]y[/tex] so we are left with only one variable: [tex]x[/tex])

Answer:

Step-by-step explanation:
Since James gave Malcolm a head start of 20 feet, Malcolm's line should start at 20 feet. So that rules out A. They were obviously going further so they went more feet, So C is ruled out because it shows them not moving, plus James didn't get a 15 foot head start which is what the C graph shows. Finally it's not B because if you look at the key at the bottom of every graph, it says that Malcolm is the dotted line, and B shows James getting a 20 foot head start, not Malcolm.

A large high school offers AP Statistics and AP Calculus Among the seniors in this school 65% take AP Statistics, 45% take AP Calculus and 30% take both If a señor is randomly selected, what the probability that they are in AP Statistics or AP Calculus but not both
Answer:
0.8
Step-by-step explanation:
P(AP statistics) = 65%
P(AP Calculus) = 45%
P(AP statistics n AP Calculus) = 30%
Probability of AP statistics or AP Calculus but not both :
Probability of event A or B :
P(AUB) = p(A) + p(B) - p(AnB)
P(AP statistics U AP Calculus) = P(AP statistics) + P(AP Calculus) - P(AP statistics n AP Calculus)
= 0.65 + 0.45 - 0.30
= 0.8
= 80%
The probability of being a senior in the AP Statistics or AP Calculus but not both when selected randomly is 0.8 or 80%.
What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
A large high school offers AP Statistics and AP Calculus. Among the seniors in this school,
65% take AP Statistics, 45% take AP Calculus,30% take both.Probabily of hapnning event A or event B, but not both can be given as,
[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]
In the problem, we have,
[tex]P(A)=0.65\\P(B)=0.45\\P(A\cap B)=0.30[/tex]
Put the values in the above formula as,
[tex]P(A\cup B)=0.65+0.45-0.30\\P(A\cup B)=0.80\\P(A\cup B)=80\%[/tex]
Thus, the probability of being a senior in the AP Statistics or AP Calculus but not both when selected randomly is 0.8 or 80%.

455 red roses
Step-by-step explanation:
Given parameters:
Number of roses sold by florist = 715
Unknown:
Number of red roses she sold = ?
Solution:
From the problem statement, we know that;
7 out of every 11 roses were red.
Let us divide the roses sold into group of 11s;

Joan is 4 feet 2 inches tall. There are 2.54 centimeters in 1 inch. What is Joan's height in centimeters? *(HINT: CHANGE HIS HEIGHT TO INCHES - HOW MANY INCHES ARE IN A FOOT? HOW MANY INCHES ARE IN 4 FEET? THEN ADD 2 INCHES) *
Answer:Joan's height is 127 centimetres
Step-by-step explanation:
Step 1
Joan is 4 feet 2 inches tall and we want to change to centimeters .
we first change her height to inches
1 Foot = 12 Inches
Therefore 4 Feet = 4 x 12 = 48 inches
Total height in inches =48 inches + 2 Inches = 50 inches
Step 2 --Now, we have gotten her height in inches, we can now change to centimetres.
We have that
1 inch =2.54 centimeters
50inches = 50 x 2.54 cm
=127 centmeters.
Joan's height is 127 centimetres
