Joy’s job pays $12.25 an hour. One day, she worked for 320 minutes. How much will she earn?
Answer:
about $64.8
Step-by-step explanation:
First of all, we know that there is 60 min per hour.
So we find out how many hours 320 minutes is equivelant to.
We can solve this by doing 320/60 = 5\frac{1}{3}
To find how much Joy makes, simply do $12.25 x $5\frac{1}{3} = 28

ABCD diagonals intersect at E. If m∠BAC=4x+5 and m∠CAD=5x-14, then find m∠CAD.
Answer: m∠CAD = 81°
Step-by-step explanation: Diagonal is a line that unites opposite sides.
ABCD is a prallelogram. One property of diagonal in a parallelogram is it separates the parallelogram in 2 congruent triangles.
The figure below shows ABCD with its diagonals.
Since diagonal divides a parallelogram in 2 congruent triangles, it means the internal angles are also congruent. So
m∠BAC = m∠CAD
4x + 5 = 5x - 14
x = 19
Then, m∠CAD is
m∠CAD = 5(19) - 14
m∠CAD = 81
The angle m∠CAD is 81°.

Find CD, if BC = 3 in
459
B В
D
Answer:
CD = (3√2)/2 = 2.12 in.
Step-by-step explanation:
Reference angle = m<BCD = 45°
Hypotenuse = BC = 3 in.
Adjacent side = CD = ??
Apply trigonometric ratio
Cos(45) = CD/3
Multiply both sides by 3
3*Cos(45) = CD
3*√2/2 = CD (cos 45 = √2/2)
(3√2)/2 = CD
CD = (3√2)/2 = 2.12

during a lunch seminar, chocolate, caramel and strawberry topping were available how many 2 topping sundaes are possible?
Answer:
There are 3 two topping sundaes possible.
Step-by-step explanation:
The order in which the toppings are chosen is not important. For example, chocolate and caramel topping is the same as a caramel and chocolate topping. So we use the combinations formula to solve this question.
Combinations Formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
How many 2 topping sundaes are possible?
2 toppings from a set of 3(chocolate, caramel and strawberry). So
[tex]C_{3,2} = \frac{3!}{2!(3-2)!} = 3[/tex]
There are 3 two topping sundaes possible.

4,320 is divisible by?
3
9
10
Answer:
3, 9, and 10
Step-by-step explanation:
To figure out whether 4,320 is divisible by these numbers, we can use their divisibility rules to help us out.
A number is divisible by 3 or 9 if its digits add up to a number divisible by 3 or 9. The digits of 4,320 add to 4 + 3 + 2 + 0 = 9, which is divisible by both 3 and 9, so 4,320 is divisible by 3 and 9.
A number is divisible by 10 if its last digit is a 0, which we have here, so 4,320 is divisible by 10.

What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, Alex paints a total of 9 dollhouses using 2 cans of paint.
So, to obtain the no. of doll houses Alex can paint with each can of paint we'll divide the total no. of dollhouses painted by the total no. of paint cans used which is,
= (9/2) dollhouses.

A new health drink has 170% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 30mg. How many milligrams of the vitamin are in the drink?
Answer:
51 mg
Step-by-step explanation:
A new health drink has 170% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 30mg.
The above question is calculated as:
RDA of the vitamin × 170%
The RDA for this vitamin is 30mg
Hence:
30mg × 170%
= 51 mg
Therefore, the milligrams of the vitamin that are in the drink is 51 mg

Which statement is an example of the transitive property of congruence?
Answer:
Step-by-step explanation:
The transitive property in general says. The transitive property of congruence states that two objects that are congruent to a third object are also congruent to each other.
if a=b and b=c, then a=c
The transitive property of congruence replaces the equal sign with a congruence symbol, and replaces a, b, c with any geometric figure. Here the geometric figures used are triangles KLM, PQR, and STU.
If ΔKLM ≅ ΔPQR and ΔPQR ≅ ΔSTU, then ΔKLM ≅ ΔSTU hope this helps
Answer:
Step-by-step explanation:
If KML=PQR and PQR = STU then KML=STU because of the transitive property of congruence.

A hiker want to determine the height of a cliff. She
has measured her height (5.8ft) and shadow (7ft).
She knows the cliff casts a shadow of 50ft. How
tall is the cliff?
Answer:
41.43 ft
Step-by-step explanation:
We solve the above using proportion
Height of cliff/Shadow of cliff = Height of Hiker/Shadow of hiker
Height of cliff = x
Shadow of cliff = 50ft
Height of Hiker = 5.8 ft
Shadow of hiker = 7 ft
Therefore:
x/50 = 5.8/7
Cross Multiply
7x = 50 × 5.8
7x = 290
x = 290/7
x = 41.428571429 ft
Approximately = 41.43 ft
Therefore, the height of the cliff = 41.43 ft
