Answer:
1.43 hours
Step-by-step explanation:
Given that:
Speed of plane A = 40 mph
Speed of plane B = 100 mph
Distance between plane A and B = 200 m
In how many hours will they meet?
Recall :
Distance = speed * time
Let the time traveled by each plane = t
Since the total distance apart = 200m
Hence,
Plane A distance + Plane B distance = total distance
40t + 100t = 200
140t = 200
Divide both sides by 140
140t / 140 = 200 / 140
t = 1.4285 hours
t = 10/7 hours or 1.43 hours
Water pours into a tank over a 10-minute period. The función f(x) graphed below models the flow rate, in gallon per minute (GPM) Over which of the following intervals does the flow rate increases by the greatest amount?
Answer:
X=0 to x =1
Step-by-step explanation:
Each figure in the sequence shown is composed entirely of 1 × 1 shaded squares. If the pattern is continued, find the quotient of the area of the enclosed inner square to the sum of the areas of the shaded squares in the 2020th figure.
Answer:
505
Step-by-step explanation:
you first do 2020x2020 because you can see from the pattern, the inside squares are 1x1, 2x2, 3x3, so the 2020th inside squares would be 2020x2020. then, you would do 2020x4 for the shaded squares because if you see from the pattern, its 1x4, 2x4, 3x4, so the 2020th would be 2020x4. then you divide [tex]\frac{2020*2020}{2020*4}[/tex] which is 505.

first to answer corretly gets brainleist! I need ya to find the slope for me!
Answer:
The slope is 3.
Step-by-step explanation:
To find the slope of this line you just have to figure out the rise over run. The rise is positive because it's going up. The run is also positive because it's going to the right. The rise would be 2 because that's how many units up the line goes until it crosses the y-intercept. The run is 3 because that's how many units over until it crosses the y-intercept. But, in this case we are not using a fraction so we just use the run which is 3.
Hope this helps! Stay safe and please mark brainliest!

The total cost for tuition plus room and board at State University is 6,584
dollars. Tuition costs 1804 dollars more than room and board. What is the
tuition fee?
Answer:
$4,194
Step-by-step explanation:
First, you need to subtract the 1,804 from the the total, which will give you 4,780. Divide this by two to get the cost of room and board, which is 2390. To find the tuition fee, add 2,390 and 1,804, and that equals $4,194.
solve the inequality 4x - 7<5
Answer:
x < 3
Step-by-step explanation:

Add 7 to both sides;
4x < 12
Divide both sides by 4;
x < 3
Answer:
x < 3
Step-by-step explanation:
Given
4x - 7 < 5 ( add 7 to both sides )
4x < 12 ( divide both sides by 4 )
x < 3

Find the equation of the line that is parallel to the given line and passes through the given point.
y = −5x + 1; (5, 7)
See attachment for math work and answer.
The equation we are looking for is parallel to the given equation. This means both equations have the same slope.
Answer:
y = -5x + 32
Step-by-step explanation:
y = -5x + 1
=> (d): 5x + y - 1 = 0
d' is parallel to the given line and passes through the given point
=> (d'): passes through (5;7)
// (d): 5x + y - 1 = 0
=> (d'): 5x + y - 32 = 0 <=> y = -5x + 32
Each of the 10 students in the baking club made 2 chocolate cakes for a fundraiser they all used the same recipe, using C cups of flour in total. Write an expression that represents the amount of flour for one cake. Use C as your variable.
Answer:
C / 20
Step-by-step explanation:
Number of students in the baking club = 10
Each student made 2 chocolate cakes
Total cakes = number of students × number of cakes per student
= 10 × 2
= 20
Total cups of flour used by 10 students = C cups
Amount of flour for one cake = Total cups of flour / Total cakes
= C / 20
The expression that represents the amount of flour for one cake = C / 20

A.) -5
Step-by-step explanation:
Slope Formula ---> [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex] m = slope
[tex]m = \frac{2 - (-3)}{-2 - (-1)}[/tex]
Eliminate negatives:

Question
What is the length of CD? In this diagram, ABC - EDC.
A. 2
B. 3
C. 4
D. 5

Answer:
C. x = 4 is the correct answerStep-by-step explanation:
To solve this, we will create a proportion.
The proportion will show the ratio of ABC to EDC and allow us to solve for x.
20 - x / 20 = x / 5
100 - 5x = 20x
100 - 5x + 5x = 20x + 5x
100 = 25x
100 / 25 = 25x / 25
4 = x
C. x = 4 is the correct answerAnswer: is 4

jessica will babysit children for $8 an hour. ciara will babysit for an appointment fee of $12 and $4 an hour. how many hours would they need to work to earn the same amount of money? if a baby sitter was needed for 5 hours, who would be less expensive?
Answer:
Answer are in bold below
Step-by-step explanation:
Question: 1
Jessica = $8
Ciara = $12 + 4 $16
Now we times both values.
16 x 8 = $128
8 x 16 = $128
They would both need to work 8 hours ft=or the same money.
Question 2:
$8 x 5 = $40
$16 x 5 =$80
Jessica will be less expensive.
Answer: 3 hours
Jessica=$8
Ciara= $4 + $12
8*3= $24
4*3= $12 +$12= $24
Because Ciara has an additional $12 fee, you have you add it on to her total.

Find x and y intercept and graph -3 + 2y = -5
Answer:
( [tex]\frac{5}{3}[/tex] , 0 ) ; ( 0 , - [tex]\frac{5}{2}[/tex] )
Step-by-step explanation:
- 3x + 2y = - 5
Coordinates of x-intercept are (x, 0)
- 3x + 2(0) = - 5 ⇒ x = [tex]\frac{5}{3}[/tex]
Coordinates of y-intercept are (0, y)
- 3(0) + 2y = - 5 ⇒ y = - [tex]\frac{5}{2}[/tex]

Answer:
similar; AA similarity; RQP
Step-by-step explanation:
We know that angle R is congruent (equal) to angle C.
We know that angle Q is congruent to angle B.
Because they ordered their triangle statement CBA, and we know that R matches C and Q matches B, you should order your statement as RQP.
What is the y-intercept of the line?
Answer:
The Y-intercept is 1
It is where the line meets the y-axis
~PumpkinSpice1
[tex]==================================[/tex]
Remember, the y-intercept is the point where the graph touches the y-axis (that's why it's called y-intercept).
Let's look at this graph and see if we can identify the y-intercept of the line.
If we look at our graph, we'll see that the line touches the y-axis at (0, 1).
[tex]\pmb{Note:-}[/tex] Remember, y-intercepts have an x-coordinate of 0.
And guess what the y-coordinate is? Yes, it's the y-intercept of the line.
Hence, the y-intercept of the line is

On multiple-Choice history Test, rita received a mark of 80%. She answer 32 correctly
Let total number of questions be x.
According to the question,
80% of x is 32
or 80/100 × x = 32
or x = 32 ÷ 80/100
or x = 32 × 100/80
or x = 32 × 10/8
or x = 4 × 10
or x = 40
So, total number of questions is 40.
