Answer:
Emmas father would be 40 years old
Step-by-step explanation:
if the father is 40 years old right now emma will be his age in 30 years.
in 30 years emma will be as old as he was when she was ten (10+30=40)
after the 30 years emmas father who was once 40 years when she asked how old he was would be 70 years old (30+40=70)
He is 40 years old.
Equation: (f+e)/2 = father's age. Here f=70 and e=10.
So, (70+10)/2 = 80/2 = 40.
Solution can be wrong. But answer is right. Answer is definitely 40 years old

John is about to take a 75-item multiple-choice test. If he finishes an average
of 5 items every 3 minutes, how long will it take him to complete the test?
1. 15 minutes
2. 25 minutes
3. 45 minutes
4. 60 minutes
Answer:
It will take John 45 minutes (option 3 or C) to finish the test.
Step-by-step explanation:
We know that John is about to take a 75-item quiz. If he finishes 5 items every 3 minutes, then we can divide 75 by 5.
75 ÷ 5 = 15
Now, let's multiply 15 minutes by 3 minutes to get the total amount of minutes.
15 x 3 = 45 minutes
Therefore, it will take John C. 45 minutes to finish the test.
Henry rode his motorcycle from his house to a friend's house. After riding 10 miles, he realizes he has traveled 2/3 of the way. How far is Bob's house from his friend's house?
A. 20 miles
B. 15 miles
C. 12 miles
D. 25 miles
Step-by-step explanation:
2/3 of diatance = 10 miles
3/3 of distance = 10 * (3/2) = 15 miles.
The distance between the houses is 15 miles. (B)
Let the total distance covered= x
Distance covered= 10 miles
According to the question,
2/3 of x= 10
=> 2/3 × x= 10
=> 2x/3= 10
=> 2x= 10× 3
=> 2x= 30
=> x= 30/2
=> x= 15
Bob's house is 15 miles away from Henry's house.

Amanda is practicing her dives off the diving board. When she dives into the water, the path her body makes and where she resurfaces can be modeled by the equation 0=2−8+7 where is the number of horizontal feet she travels. Solve the equation to find the number of feet she will travel before coming back to the surface of the water.
Answer:
The number of feet she will travel back is 1 or 7 feet
Step-by-step explanation:
Here, we need to solve the quadratic equation
That will be as follows;
0 = x^2 -8x + 7
x^2-x-7x+ 7 = 0
x(x-1)-7(x-1) = 0
(x-1)(x-7) = 0
x = 1 or 7
The number of feet she will travel before coming back to the surface of the water is 1 or 7 feet
10. A ladder 6.5 metres long leans against a wall,
touching a window sill, and makes an angle of
62° with the ground. Find the height of the
window sill above the ground. How far is the
foot of the ladder from the foot of the wall?
Answer:
5.74m, 3.05m
Step-by-step explanation:
The set up is a right angled triangle.
Length of the ladder is the hypotenuse = 6.5m
Angle of elevation = 62°
Required
Height of the window (opposite)
Using SOH CAH TOA trigonometry identity
Sin theta = opp/hyp
Sin62 = opp/6.5
Opp = 6.5sin62
Opp = 5.74m
Hence the height of the window is 5.74m
The distance of the ladder from the foot of the wall is the adjacent
Cos 62 = adj/6.5
adj = 6.5cos62
adj = 3.05m
Hence the distance of the ladder from the foot of the wall is 3.05m

Answer:
i think you got it by now
Step-by-step explanation:
Answer:
Step-by-step explanation:
four shortcuts allow students to know two triangles must be congruent: SSS, SAS, ASA, and AAS. Knowing only side-side-angle (SSA) does not work because the unknown side could be located in two different places. ... Because there are 6 corresponding parts 3 angles and 3 sides, you don't need to know all of them.

Which function is equivalent to f(x) = -4(x + 7) – 6?
Answer:
f(x) = - 4x - 34
Step-by-step explanation:
Given
f(x) = - 4(x + 7) - 6 ← distribute parenthesis
= - 4x - 28 - 6 ← collect like terms
= - 4x - 34
Write an equation to represent the following statement.
33 is 15 less than k.
Answer:
33 = k - 15
Step-by-step explanation:
This question can be solved but if your asking about equation 33 = k - 15 is it, because 33 is the total and 15 is less than k, whenever you see less than the number before is always the number telling the other number to subtract, such as 44 is 16 less than a number, the answer will be 44 = x - 16.

A card is drawn from an ordinary deck of cards. What is the probability that the card is a king given that the card is red?
A. P(K|R) = 0.8
B. P(K|R) = 0.2
C. P(K|R) = 0.92
D. P(K|R) = 0.08
Answer:
d. 0.08
Step-by-step explanation:
52 cards in a deck of cards. 26 are red. there are 2 red kings. 2/26= 0.076 which rounds up to 0.08
Half the cards (26) are red
Then there are 2 red kings out of the 26.
Probability of picking a red king out of the red cards is 2/26 = 1/13 = 0.076
Round to 0.08

If f (x) = 4 x - 3, what is f (x)^-1 ?
Answer:
Step-by-step explanation:
f(x) = 4x - 3
.
The problem asks you to find f(-1).
.
All that this is telling you to do is to evaluate f(x) when x equals -1. So, just go to the
given f(x) and substitute -1 for every x.
.
Starting with:
.
f(x) = 4x - 3
