Mrs. Johnson gets her morning coffee. She can't decide which size to order. Which size is the better buy? Explain.
Small- 12 oz for $3.95
Medium- 16 oz for $4.25
Large- 20 oz for $4.55
Answer:
large
Step-by-step explanation:
3.95 divided by 12 = 0.33
4.25 divided by 16 = 0.27
4.55 divided by 20 = 0.2275
the 20oz is the least unit price

Find the matrix product, if possible.
Answer:
below.
Step-by-step explanation:
The number of columns in the first matrix must equal to the number of rows in the second for multiplication to be possible.
Here first matrix has 3 columns and second one has 3 rows so POSSIBLE.
[ -8 2 2] { 3 }
[ 0 ]
[ -3]
= -8*3 + 2*0 + 2 * -3 = [-30] <-------- Answer.
Note a 1*3 matrix multiplied by a 1*3 matrix gives a 1*1 result.

Find the base of a triangle whose altitude is 12 cm and area is 96 cm
Given:
Altitude of a triangle = 12 cm
Area of the triangle = 96 sq. cm
To find:
The base of the triangle.
Solution:
The area of a triangle is
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
Putting Area = 96 and height = 12, we get
[tex]96=\dfrac{1}{2}\times base\times 12[/tex]
[tex]96=6\times base[/tex]
Divide both sides by 6.
[tex]\dfrac{96}{6}=base[/tex]
[tex]16=base[/tex]
Therefore, the base of the triangle is 16 cm.
Solve for x. Round answer to the nearest tenth (0.1).
Answer:
x = 9.9
Step-by-step explanation:
This is a isosceles triangle, with sides measurements (1 , 1 , √2), and the angles being (45° - 45° - 90°). Note that the side measurements of 1 is opposite of that of a 45°, while the measurement of √2 is opposite of that of 90°.
In this case, multiply. The side measurement of 1 has 7.
1 x 7 = 7
In the same, you must multiply 7 with √2
x = 7 * √2 = 7√2.
√2 = ~1.414
7 x 1.414 = 9.898
Round to the nearest tenth:
9.898 rounded to the nearest tenth = 9.9
x = 9.9
~
Answer:
9.9 is your answer
Step-by-step explanation:
by using Pythagoras law
p²+b²=h²
7²+7²=x²
x=√{2×49)=7√2or 9.9 is your answer

4--9w^2
Can Someone help PLS
Answer:
Step-by-step explanation:
Use the identity: a² - b² = (a + b)(a- b)
4 - 9w² = 2² - (3w²)
= (2 + 3w)(2 - 3w)
what is the measure of the base angle,x, of the isosceles triangle shown below? round your answer to the nearest tenth of a degree.
Answer:
x ≈ 49.7°
Step-by-step explanation:
Since, the given triangle is an isosceles triangle,
Two sides having measure 17 units are equal.
Opposite angles of these equal sides will be equal.
Measure of the third angle = 180° - (x + x)°
By sine rule,
[tex]\frac{\text{sinx}}{17}=\frac{\text{sin}(180-2x)}{22}[/tex]
[tex]\frac{\text{sinx}}{17}=\frac{\text{sin}(2x)}{22}[/tex] [Since, sin(180 - θ) = sinθ]
[tex]\frac{\text{sinx}}{17}=\frac{2(\text{sin}x)(\text{cos}x)}{22}[/tex]
[tex]\frac{\text{sinx}}{17}=\frac{(\text{sin}x)(\text{cos}x)}{11}[/tex]
[tex]\frac{1}{17}=\frac{(\text{cos}x)}{11}[/tex]
cos(x) = [tex]\frac{11}{17}[/tex]
x = 49.68°
x ≈ 49.7°

Find the measure of CB.
Answer:
I'm Pretty Sure Its 40.
Step-by-step explanation:
Answer:
CB = 20.
Step-by-step explanation:
If the triangle is Isosceles, assuming that <D = <B according to the markings, CB must be 20 since 32 is the greatest side and therefore the hypotenuse, 20 is the smaller side and therefore either opposite or adjacent. Given that two sides must be the same, since CB is opposite of angle D which is congruent to angle B, CB = side opposite of angle B = 20.
