Answer:
4/9 cup of sugar
Step-by-step explanation:
[tex]\frac{1}{3} cup of sugar= \frac{3}{4} cup of flour[/tex]
[tex]? cup of sugar=1 cup of flour[/tex]
so crisscross them and finally you'll get
1/3*4/3=4/9
For 1 cup of flour, 4/9 cups of sugar is needed.
What are ratios and proportion?Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other. A statement expressing the equality of two ratios A:B and C:D is called a proportion. We can express proportion as -
A : B ∷ C : D
AND
A x D = B x C
Product of extremes equal to product of means.
Given is a recipe that requires 1/3 cup of sugar for every 3/4 cup of flour.
Now -
For 1/3 cup of sugar = 3/4 cup of flour is needed.
For 1 cup of flour = (1/3)/(3/4) cups of sugar = 1/3 x 4/3 = 4/9 cups of sugar is needed.
Therefore, for 1 cup of flour, 4/9 cups of sugar is needed.

Answer:
(4+x)^2
Step-by-step explanation:
Rewrite 16 as 4^2
4^2+8x+x^2
Check the middle term by multiplying 2ab and compare the result with the middle term in the original expression.
2ab=(2)x(4)x(x)
Factor using the perfect square trinomial rule a^2+2ab+b^2=(a+b)^2, where a=4 and b=x

Step-by-step explanation:
(1)
Given
g(r) = (r + 14)² - 49
To obtain the zeros, let g(r) = 0 , that is
(r + 14)² - 49 = 0 ( add 49 to both sides )
(r + 14)² = 49 ( take the square root of both sides )
r + 14 = ± [tex]\sqrt{49}[/tex] = ± 7 ( subtract 14 from both sides )
r = - 14 ± 7, then
r = - 14 - 7 = - 21 ← smaller r
r = - 14 + 7 = - 7 ← larger r
(2)
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
g(r) = (r + 14)² - 49 ← is in vertex form
with vertex = (- 14, - 49 )
Samy's car can hold 20 gallons of

can travel 15 miles for every gallon of
gasoline.
Rosa car has 13 gallons of gasoline in
the fuel tank and she can travel 19 miles
for every gallon of gasoline.
If they both start at the same place and
travel at the same constant speed, who
will go farther?
Answer:.
Justification:
Answer:
Rosa will go farther.
Step-by-step explanation:
1. Samy's travel distance.
3/4 of 20
3/4 * 20 = 15 gallons
15 miles for every gallon
15 * 15 = 225
Samy's travel distance is 225 mIles
2. Rosa travel distance.
13 gallons
19 miles for every gallon
19 * 13 = 247 mIles
Rosa's travel distance is 247 mIles.

A bag contains 14 green tiles,10 red tiles, and 16 blue tiles. Brodie randomly draws a tiel, records the color , and replaces the tile.if he does this 80 times, how many times should he expect to draw a red tile
Answer:
20 red tiles
Step-by-step explanation:
14 green tiles,10 red tiles, and 16 blue tiles. = 40 tiles
P(red) = 10/40 = 1/4
If we draw 80 tiles
80 * 1/4 = 20
We should expect 20 red tiles

A 13-foot board is cut into two pieces. The length of the shorter piece is 1 ft more than half the length of the longer piece. Find the length (in ft) of the shorter piece.
Answer: 1
Step-by-step explanation: 1
Length of the shorter piece of board is equals to 5foot.
What is length?
" Length is defined as the distance between two end points of any object."
According to the question,
Length of the board = 13foot
'l' represents the length of the longer piece
As per the condition given we have,
Length of the shorter piece = [tex]\frac{l}{2} +1[/tex]
Therefore,
[tex]l + \frac{l}{2}+1=13[/tex]
⇒ [tex]\frac{3l}{2} =13-1[/tex]
⇒[tex]l= \frac{2}{3} (12)[/tex]
⇒ [tex]l= 8foot[/tex]
Length of the shorter piece = [tex]\frac{8}{2} +1[/tex]
= [tex]5foot[/tex]
Hence, length of the shorter piece of board is equals to 5foot.

(a) Find the gradient of line AB.
(b) Find the y-intercept of line AB.
(c) A second line PQ is parallel to the line AB and passes through a point (2, -8).
Show that the second line PQ also passes through the point(-1,-5)
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
[tex]\frac{x}{2}[/tex] + [tex]\frac{y}{2}[/tex] = 1 ( multiply through by 2 to clear the fractions )
x + y = 2 ( subtract x from both sides )
y = - x + 2 ← in slope- intercept form
(a) with slope m = - 1
(b) with y- intercept c = 2
(c)
Parallel lines have equal slopes, thus
y = - x + c ← is the partial equation of PQ
To find c substitute (2, - 8) into the partial equation
- 8 = - 2 + c ⇒ c = - 8 + 2 = - 6
y = - x - 6 ← equation of PQ
To show (- 1, - 5) lies on PQ, substitute x = - 1 into the equation and evaluate for y.
y = - (- 1) - 6 = 1 - 6 = - 5 ← the given y- coordinate
Thus PQ passes through (- 1, - 5 )

The Happy-Go-Lucky Beach was 163 feet long from parking lot to high tide. After last year's hurricane came ashore, the beach only measured 154 feet
long. What was the percent of change?
About 94.5% of increase
About 94.5 % of decrease
About 5.5% increase
About 5.5% decrease
Answer:
About 5.5% decrease
Step-by-step explanation:
Here, we want to calculate the percentage increase or decrease and its value.
The first thing to do here is to check if we are going to have a decrease or an increase.
since the value before the change is higher than the value after the change, then what we have is a decrease.
Mathematically, the percentage decrease is calculated as follows;
% decrease = (old value - new value)/old value * 100%
old value = 163 feet
new value = 154 feet
% decrease = (154-163)/163 * 100%
% decrease = -9/163 * 100%
% decrease = -5.52%
Thus the best answer is about 5.5% decrease

Find the volume of the pyramid. 100 points
120 yd^3
Step-by-step explanation:
The formula for the volume of a pyramid is...
[tex]V=\frac{1}{3}Bh[/tex]
B is the area of the base and h is the height from the middle of the pyramid to the top. Since we know both of these we can plug them in.
[tex]V=\frac{1}{3}(45*8)[/tex]
[tex]V=\frac{1}{3}*360[/tex]
[tex]V=[/tex]
120
The volume for the pyramid is 120 yd^3.
Answer:
120 yards ^3
Step-by-step explanation:
To solve we need to know the formula.
The formula for the volume of a pyramid is 1/3 B * H
B= 45 and H = 8. We can sub those values in to the formula to solve.
= 1/3 45*8
= 1/3 360
=120
Since we multiplied yd^2 by yd, we get yd^3
So the answer is 120 yd^3

The results for each friend are shown in the tables. Find the relative frequency for the event "heads" for each friend. If the friends combine their results to get 101 heads and 112 tails, what is the relative frequency for the event "heads"? Use pencil and paper. Suppose each friend flips a coin 710 times. Is there a value you would expect the relative frequency for the event "heads" to be close to?
For friend 1, the relative frequency is [tex]\frac{25}{71}\approx 0.352.[/tex]
For friend 2, it's [tex]\frac{53}{71}\approx 0.746,[/tex] and for friend 3, it's [tex]\frac{23}{71}\approx 0.319.[/tex]
Combining the data of all three would give a relative frequency of [tex]\frac{101}{213}\approx 0.474.[/tex]
If each friend were to flip a coin 710 times, assuming the coin to be a fair coin, we'd expect about half of the flips to be heads, so the relative frequency would be close to 0.5.
