jessie hiked 5(1/2) miles on sunday and 6(3/4) miles on sunday .how many miles did jessie hike altogether ?
Answer: 12 1/4 miles
Step-by-step explanation:
jessie hiked 5 1/2 + 6 3/4 = lets convert the integers in fractions
= 11/2 + 27/4 = common denominator is 4
22/4+27/4= 49/4 = 12 1/4 miles
. Leslie is blowing up one of her favorite photographs to hang on her wall. If the photo's original length and height were 8 inches and 15 inches, and the new height is 4 feet, how many feet must the new picture be
Answer:
[tex]L_2 = 2\frac{2}{15}\ ft[/tex]
Step-by-step explanation:
Given
Original
[tex]Length(L_1) = 8\ in[/tex]
[tex]Height (H_1) = 15\ in[/tex]
New
[tex]Height (H_2) = 4\ ft[/tex]
Required
Determine the new length (L2)
Since the original photographs was blown up; the original and the new photographs would have the same ratio
i.e.
[tex]Ratio = L_1 : H_1[/tex]
and
[tex]Ratio = L_2 : H_2[/tex]
Equate both ratios
[tex]L_1 : H_1 = L_2 : H_2[/tex]
Rewrite as fraction
[tex]\frac{L_1}{H_1} = \frac{L_2}{H_2}[/tex]
Substitute values for L1, H1 and H2
[tex]\frac{8}{15} = \frac{L_2}{4}[/tex]
Multiply both sides by 4
[tex]4 * \frac{8}{15} = \frac{L_2}{4} * 4[/tex]
[tex]4 * \frac{8}{15} = L_2[/tex]
[tex]\frac{4 * 8}{15} = L_2[/tex]
[tex]\frac{32}{15} = L_2[/tex]
[tex]2\frac{2}{15} = L_2[/tex]
[tex]L_2 = 2\frac{2}{15}\ ft[/tex]
The new length must be [tex]2\frac{2}{15}\ ft[/tex]
The new picture must be [tex]2\frac{2}{15}[/tex] feet or 2.1334 feet in length.
We know, [tex]1\ inch= \frac{1}{12}\ feet[/tex]
Given to us:
Initial length, [tex]L_i =8 inches[/tex];
Initial height, [tex]H_i =15\ inches[/tex];
Final height, [tex]H_f = 4\ feet[/tex];
We know that a when a picture is blown up(enlarged), it is always done in a specific ratio, therefore
Ratio, [tex]r=\dfrac{Length}{Height}[/tex]
So,
[tex]\dfrac{Initial\ Length}{Initial\ Height} =\dfrac{Final\ Length}{Final\ Height}[/tex],
[tex]\dfrac{8}{15} =\dfrac{Final\ Length}{4}\\\\{Final\ Length}=\dfrac{8}{15} \times 4 \\\\{Final\ Length}=\dfrac{32}{15}\\\\{Final\ Length}=2\frac{2}{15}\ feet[/tex]
Hence, the new picture must be [tex]2\frac{2}{15}[/tex] feet or 2.1334 feet in length.

Calculate the speed of a wave with a frequency of 2 Hz, amplitude of 3m, and a wavelength of 10m
The speed of a wave is the product of the wavelength and its frequency.
The speed of the wave is 20m/s
Given
[tex]\lambda = 10m[/tex] --- the wave length
[tex]f =2Hz[/tex] --- the frequency
[tex]A = 3m[/tex] --- the amplitude
The speed of wave (v) is calculated as follows:
[tex]v =f\lambda[/tex]
Substitute values for f and [tex]\ambda[/tex][tex]\lambda[/tex]
[tex]v = 2Hz \times 10m[/tex]
[tex]v = 20ms^{-1}[/tex]
Hence, the speed of the wave is 20m/s

Step-by-step explanation:
A teacher surveyed her class about their online accounts and wanted to know if they had “Fb” accounts or if they had “Snap ” accounts. The Venn diagram shows her results. If a person from the class is randomly selected, what is the probability that the person has a “Fb” account but not a “Snap” account
a)1/5
b)16/25
c)7/25
d)18/25
Answer:
a) 1/5
Step-by-step explanation:
There are 25 students total in the class.
If you look at the Venn Diagram, you can see that only 5 people have only "Fb" accounts.
Therefore, the probability that the person has a “Fb” account but not a “Snap” account is 5/25 or 1/5.

a triangle has a base of 16 inches and a height of 1/8 inches what is the area
Answer:
the area is 2
Step-by-step explanation:
The area of the triangle will be 1 inch².
What is a triangle?
A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angle of a triangle is always equal to 180°.
Given that the height of the triangle is 1/8 inches and the base of the triangle is 16 inches. Therefore, the area of the triangle will be,
Area of the triangle = 0.5 × Height × Base
= 0.5 × (1/8) inches × 16 inches
= 1 inch²
Hence, the area of the triangle will be 1 inch².

A. 18
A matrix is a rectangular array of numbers arranged in rows and columns. The array of numbers below is an example of a matrix. The number of rows and columns that a matrix has is called its dimension or its order. By convention, rows are listed first; and columns, second.Here the matrix contains 48 elements and the factors of 48 are
48×1,1×48
24×2,2×24
12×4,4×12
6×8,8×6
3×16,16×3
So, 18 is not the factor of 48.
16, 8, and 24 can go into 48 but not 18.

Find the x and y-intercepts of the equation. Then calculate the points at constant intervals and plot and connect those points on a makeshift graph. A quadratic equation can have 2 solutions, 1 solution, or none. The corresponding graphs(if two solutions) would most probably cross over the x-axis twice.
