Answer:
20 apples, 32 pears
Step-by-step explanation:
Using a for number of apples and p for number of pears, you get a+p=52 (amount) and 0.4a+0.5p=24 (cost).
One way of solving simultaneous equations is using like terms and adding/subtracting them to remove a variable. There aren't any like terms here, but we can create some by multiplying terms.
Multiplying the second equation by 2 gives 0.8a+p=48, so that makes a like term.
Since the symbols are the same in front of the like term, we subtract the second term from the first one. This gives 0.2a=4.
Dividing by 0.2 gives a=20.
We can sub this into either equation to get the value of p.
a+p=52, so 20+p=52, meaning p=32.

(X^1/4 y^16)^1/2?
Answer:
[tex]x^{\frac{1}{8} } y^{8}[/tex]

Whats the surface area of a cube whose volume is 1664??
Answer:
A≈842.53
:))))
Volume = side³
=> 1664 = side³
=> ³√1664 = side
=> 4 (³√26) = side
=> 4 (26^1/3) = side
Surface area = 6 side²
=> Surface area = 6 × [4 (26^1/3)]²
=> Surface area = 6 × 140.42 [approximately]
=> Surface area = 842.54 [approximately]

Answer:
24 sq. m
Step-by-step explanation:
Area of the grass part = area of the park - area of sand area
Park:
l = 6 m ; w = 5 m
Area of park = l * w = 6*5 = 30 sq.m
Sand :
l = 3 m ; w = 2 m
Area of sand part = 3*2 = 6 sq.m
Area of grass part = 30 - 6 = 24 sq.m
Answer:
24 square meters is the area of the grass part.
Step-by-step explanation:
Multiply both sides of the "sand" section, which are 2 and 3. You get 6.
Now multiply two numbers, 5 and 6, to find the square meters of the whole area, including grass and sand, you get 30.
Now since you only need the area of the grass area, you subtract the area of the sand area, which is 6 sq meters, from the whole area, 30 sq meters, leaving you with 24 square meters as the answer.

Erin's jewelry box is in the shape of a rectangular prism. The measurements of the jewelry box are length 5 in, width 10 in, and height 3 in. What is the surface area of Erin's jewelry box?
Answer:
190 square inches
Step-by-step explanation:
Surface area of a rectangular prism formula is given as
2(LW + LH + WH)
Where
L = Length = 5in
H = Height = 3in
W = Width = 10in
Hence:
Surface area = 2(5 × 10 + 5 × 3 + 3 × 10) square inches
= 2 × (50 + 15 + 30) square inches
= 2 × (95) square inches
= 190 square inches
Therefore, the surface area of Erin's jewelry box is 190 square inches

Find (-4) for f(x) = 9(3)^x
A. -108
B. 1/3
C. -729
D. 1/9
Answer:
D
Step-by-step explanation:
9(3)^-4
3^2 × (3^-4)
in algebraic expression a^n × a^m = a^n+m
3^2+(-4)
3^-2
but 3^-2 = 1/3²
1/3²= 1/9
The option (4) is correct i.e., when [tex]x=-4[/tex] then
[tex]f(x) = 9(3)^x\\\\f(x)=\frac{1}{9}[/tex]
What is the equation?
The definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here given equation is
[tex]f(x)=9(3)^x\\\\\\x=-4\\\\\\f(-4)=9(3)^{-4}\\\\f(-4)=\frac{9}{(3)^4}\\\\f(-4)=\frac{9}{81}\\\\f(-4)=\frac{1}{9}[/tex]
Hence, the option (4) is correct i.e., when [tex]x=-4[/tex] then
[tex]f(x) = 9(3)^x\\\\f(x)=\frac{1}{9}[/tex]

What are the coordinates of the point on the directed line segment from (1,−6) to (8,8) that partitions the segment into a ratio of 4 to 3?
The coordinate of the point on the directed line segment that partitions the segment into a ratio of 4 to 3 is (29/7,50/7)
How to determine the coordinate at the partition?The given parameters are:
A = (-1,6)
B = (8,8)
Ratio, m : n = 4 : 3
The coordinate at the partition is calculated using:
[tex](x,y) = \frac{1}{m + n} * (mx_2 + nx_1,my_2 + ny_1)[/tex]
So, we have:
[tex](x,y) = \frac{1}{4 + 3} * (4 * 8 + 3 * -1,4 *8 + 3 * 6)[/tex]
Evaluate
[tex](x,y) = \frac{1}{7} * (29,50)[/tex]
Evaluate the product
(x,y) = (29/7,50/7)
Hence, the coordinate of the point is (29/7,50/7)

The type of Polygon shown as given in the question with its' shape is called; Convex Hexagon
How to define Polygons?We are told that the polygon has 6 sides and that no angle goes inside the shape.
Now, a polygon with 6 sides is called a hexagon. However, in this case the name will be a convex hexagon because it will have a hexagonal shape with no interior angle greater than 180°.
Despite that said, regular hexagons will always be called convex hexagon while Irregular hexagons can also be called convex hexagons.

Explanation:
The mixed number 7 & 1/4 converts to the decimal form 7.25, since 1/4 = 0.25
The ratio 1:7.25 means that we'll multiply the smaller triangle's sides by the scale factor 7.25 to get the larger corresponding side
Meaning that the value of x is 3*7.25 = 21.75
This converts to the mixed number 21 & 3/4

Step-by-step explanation:
A candle is 6 tall after burning for one hour. After 3 h, it is 5. 5 tall. Write a linear equation to model the hh () of the candle after burning () h.
Answer:
h(t) = -0.25t + 6.25
Step-by-step explanation:
Given that :
Height of candle after burning for 1 hour = 6
Height of candle after burning for 3 hours = 5.5
The linear model to show the height ight of candle after burning for h hours :
The height change per hour of burn ; this is the slope ;
Change in height / Change in time ;
Time = 1 hour ; height = 6
Time = 3 hours ; height = 5.5
Slope = (5.5 - 6) / (3 - 1) = - 0.5 / 2 = - 0.25
This means candle height decreases ; - 0.25 ft per hour :
Based on the linear, slope, intercept equation ;
y = mx + c
Candle height, h
h(t) = mt + c
c = intercept, we can obtain this thus ;
Using the height at 1 hour and slope;
After an hour burn :
6 = - 0.25t + c
t = 1
6 = - 0.25(1) + c
6 = - 0.25+c
6+0.25 =, c
c = 6.25
Hence ; to calculate height, h after burn time &
h(t) = -0.25t + 6.25
