A baker used 5 7/10 bags of flour one week. The same baker used 7 3?10 bags the next week. How many more bags of flour did the baker use the second week than the first week?
Answer:
B. 1 6/10
Step-by-step explanation:
”How many more” means find the difference.
So first you convert the fractions:
5 7/10= 57/10
7 3/10=73/10
Subtract the two converted fractions and you get a difference of 16/10 then you will simply 16/10, which becomes 1 6/10.

Corrie is 5 inches taller than Jason who is 4 ft. 9 in. Jennifer is
8 in, shorter than Corrie. How tall are Corrie and Jennifer?
(Express answers in simplest terms.)
Corrie___________.
Jennifer ___________.
Answer:
see below
Step-by-step explanation: 5 27 6 46
Corrie is 5 inches taller than Jason who is 4 ft. 9 in
Corrie must be 4 ft. 9 in + 5 in. = 5 ft. 2 in or convert ft to inches and add
[4(12) + 9] + 5 = 62 62/12 = 5 ft. 2 in.
Jennifer is 8 in, shorter than Corrie so Corrie is (5 - 8) inches (-3) inches taller than Jason or 3 in. shorter than Jason
Jennifer is 4 ft. 9 in - 3 in. = 4 ft. 6 in

Reba kicks a soccer ball off the ground and in the air, with an initial velocity of 25 feet per second. Using formula H(t) = - 1612 + vt + s, what is the maximum height the soccer ball reaches?. Using the formula HC -1662 + vt +s, what is the maximum height the soccer ball reaches?
Answer:
The maximum height the soccer ball reaches is 9.77 feet.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].
Reba kicks a soccer ball off the ground and in the air, with an initial velocity of 25 feet per second.
The formula for the height is:
[tex]h(t) = -16t^2 + v(0)t + h(0)[/tex]
In which v(0) is the initial velocity and s(0) is the initial height.
Initial velocity of 25 feet per second means that [tex]v(0) = 25[/tex]
Kicked off the ground means that [tex]h(0) = 0[/tex]. So
[tex]h(t) = -16t^2 + 25t[/tex]
Which is a quadratic equation with [tex]a = -16, b = 25, c = 0[/tex].
The maximum value is:
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
In which
[tex]\Delta = b^2-4ac = 25^2 - 4(-16)(0) = 625[/tex]
[tex]y_{v} = -\frac{\Delta}{4a} = \frac{625}{4(16)} = 9.77[/tex]
The maximum height the soccer ball reaches is 9.77 feet.

SURFACE AREA: The measure of the total area that an object occupies.
The formula for finding the surface area for a cylinder is:
[tex]SA=2\pi r^2+2\pi rh[/tex]
[tex]r-radius[/tex]
[tex]h-height[/tex]
Mathematics: Solve.
According to the image, the cylinder has a height of 9 inches and a base radius of 4 inches.
Now, we can plug the numbers into the formula.
[tex]SA=2\pi 4^2+2\pi4*9- (2*3.14*4*4)+(2*3.14*4*9)=326.56.[/tex]
Mathematics: Conclude.
Therefore, the surface area of this cylinder is 356.56 in².

Answer: d
Step-by-step explanation:
A tortoise and hare are competing in a race. The function f and g are such that f(t) represents the tortoise's distance from the finish line (in meters) t seconds after the start of the race and g (t) represents the hare's distance from the finish line (in meters) t seconds after the start of the race.
If we want to compute the number of seconds needed for the hare to finish the race, which of the following procedures should be used?
A. Solve g(t)=0 for the value of t.
B. Solve g(t)=1000 for the value of t.
C. Evaluate g(0).
D. Solve f(t)=g(t) for the value of t.
E. Evaluate g(1000).
Answer:
g(t) = 0; solve for t
Step-by-step explanation:
Given
Options (a) to (e)
Required
Which of the options is true
From the question, we understand that: g(t) represents hare's time to complete the race
At the beginning of the race, the time left to complete the race is at g(t) = 0; then solve for t.
Take for instance:
[tex]g(t) = 10 - t[/tex]
The time to complete the race is: g(t) = 0
So, we have:
[tex]0 = 10 - t[/tex]
Collect like terms
[tex]t = 10[/tex]
To determine the number of seconds that the hare would finish the race, we solve g(t) = 0, to calculate the value of t.
Linear equation
Linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the equation (rate of change) and b is the y intercept (initial value of b).
Given that g (t) represents the hare's distance from the finish line (in meters) t seconds after the start of the race.
To determine the number of seconds that the hare would finish the race, we solve g(t) = 0, to calculate the value of t.

The distance by road from town A to town B is 257 km. What is 50% of that distance?
Answer: 128.5km
Step-by-step explanation:
Since we are given the information that the distance by road from town A to town B is 257 km. To get 50% of the distance, we simply have to multiply the distance given by 50%. This will be:
= 50% × 257km
= 50/100 × 257km
= 0.5 × 257km
= 128.5km
Therefore, 50% of the distance is 128.5km.

Answer:
Step-by-step explanation:
angle 3 and angle 4 are co interior angles.so,
angle 3+angle 4=180 degree
sum of co interior angle is always 180 degree.
Answer: Angle 3 and 5 = 180° because consecutive angles formed by parallel lines are supplementary
Step-by-step explanation:
It should be noted that Angle 3 and 5 = 180° because consecutive angles formed by parallel lines are supplementary.
For example, if angle 3 is 60°, the value of angle 5 will be:
= 180° - 60°
= 120°

What scale factor was used to transform f(x) into g(x)?
Answer:
The scale factor is k = 4.
Step-by-step explanation:
In the graph, we can see that g(x) is a dilation from f(x)
And a general vertical dilation of scale factor k is written as:
g(x) = k*f(x)
So here we want to find the value of k.
In the graph, we can see that:
f(1) = 1.5
f(3) = 0.5
Now, the values of g(x) in those x-values are:
g(1) = 6
g(3) = 2
And we must have:
g(1) = k*f(1)
g(3) = k*f(3)
we should get the same value of k in both equations, now let's replace the values of the functions:
For the ones evaluated in x = 1, we get:
6 = k*1.5
6/1.5 = k = 4
for the cases evaluated in x = 3, we get:
2 = k*0.5
2/0.5 = k = 4
In both cases we got the same value of k, so we can conclude that the scale factor from f(x) into g(x) is k = 4
