Answer:
m∠a = 60°
Step-by-step explanation:
Hi there,
Before answering this question, you should know that the sum of all the angles in a triangle will always be 180°. Therefore, we can write this equation to find the value of ∠a :
70° + 50° + m∠a = 180°
Solve for m∠a
120° + m∠a = 180°
m∠a = 60°
Hope this answer helps. Cheers.

Kishany is investing in a savings account that earns 3.85% interest compounded annually. How much will Kishany have in the account at the end of the 3rd year if she deposits $600 in the account?
a
$2,310
b
$672.00
c
$558.38
d
$669.30
Answers
Answer:
b: $672
Step-by-step explanation:
The appropriate formula for use here is the Compound Amount formula:
A = P(1 + r)^n, where r is the annual interest rate as a decimal fraction, P is the principal (up front amount invested), and t is time measured in years.
Here we have A = ($600)(1 + 0.0385)^3, or:
A = ($600)(1.0385)^3
A = $672 (matches answer b)
Which statement about 192' is correct?

Step-by-step explanation: took the test
Inequalities help us to compare two unequal expressions. The statement that is correct about 192° is option C.
What are inequalities?Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
The statement that is true about 192° can be found by simplifying the given expression. Therefore, The value of the options can be simplified as shown below,
Cos(192°) > 0 ⇒ -0.978 > 0
Tan(192°) < 0 ⇒ 0.212 <0
Sin(192°) < 0 ⇒ -0.2079 < 0
As it can be observed that only the third inequality is true. Therefore, the statement that is correct about 192° is option C.

A shipping container is in the shape of a right rectangular prism with a length of 13
feet, a width of 15 feet, and a height of 10 feet. The container is completely filled with contents that weigh, on average, 0.39 pound per cubic foot. What is the weight of the
contents in the container, to the nearest pound?
Answers
Answer:
371 pounds
Step-by-step explanation:
First you find how much space is in the container
length is 13
width is 15
height is 10
2 * (15 * 13 + 10 * 13 + 10 * 15)= 950
The total space in the container is 950
Then multiply it by 0.39 to find the weight
950 * 0.39 = 370.5
Round to the nearest pound
.5 rounded is rounded to a whole number

Where do the graphs of y = 4x - 3 and y = 9x - 13 intersect?
Someone help me asap plz!
Answers
Answer:
(2, 5 )
Step-by-step explanation:
To find the point of intersection, solve the equations simultaneously.
y = 4x - 3 → (1)
y = 9x - 13 → (2)
Substitute y = 9x - 13 into (1)
9x - 13 = 4x - 3 ( subtract 4x from both sides )
5x - 13 = - 3 ( add 13 to both sides )
5x = 10 ( divide both sides by 5 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
y = 4(2) - 3 = 8 - 3 = 5
point of intersection = (2, 5 )

Step-by-step explanation:
The sum of the 3 angles in a triangle must equal 180°
(1) 60 ° + 80° + 80° = 220° ≠ 180°
(2) 90° + 90° = 180° ( with only 2 angles, no third angle
(3)
obtuse angles are greater than 90° but less than 180° , so their sum would be greater than 180°
(4) 55° + 60° + 65° = 180°
option 4 is the correct condition

Monica paid sales tax of $2.40 when she bought a new bike helmet. If the sales tax rate was 6%, how much did the store charge for the bike helmet before tax?
Answers
Answer: $40
Step-by-step explanation:
The tax rate is 6% on the price of the good bought.
This means that $2.40 is 6% of the price of the helmet before taxes.
Assuming the before tax price is x, the price of the helmet is:
2.40 = x * 6%
x = 2.40 / 6%
x = $40
$40 is the before tax cost.
state the coordinate of the image of the given point B (-10, -6) under a dilation with a center at the orgin with the given scale factor k = 1/2
Answers
The coordinate of the point B ( -10 , -6 ) after the dilation of -1/2 is given by the coordinate B ' ( -5 , -3 )
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
Given data ,
Let the coordinate of the point be represented as B
The value of B = B ( -10 , -6 )
Now , the dilation factor is given by k = 1/2
So , multiply by 1/2 on the x coordinate and y coordinate of the point B , we get
The coordinate of the point B' after the dilation is
B' = B' ( -10/2 , -6/2 )
So , on simplifying the equation , we get
B' = B' ( -5 , -3 )
Hence , the point after dilation is B' ( -5 , -3 )
