Answer:
280km
Step-by-step explanation:
Distance formula = Speed x Time
given Speed = 70km/h and
time taken = 4 hours (from 2pm to 6pm),
Distance between 2 towns = Speed x Time taken
= 70 x 4
=280km
On a map, 9 cm represents 15 miles. If the distance between two cities on the map is 15 cm, how many miles separate the cities?
Answer:
15 cm on the map is equal to 25 miles.
Step-by-step explanation:
Given that,
On a map, 9 cm represents 15 miles.
The distance between two cities is 15 cm. We need to find the distance in miles.
9 cm = 15 miles
[tex]1\ cm=\dfrac{15}{9}\ \miles[/tex]
So, 15 cm is equal to,
[tex]15\ cm=\dfrac{15}{9}\times 15\ miles\\\\=25\ miles[/tex]
So, 15 cm on the map is equal to 25 miles.

A thermometer falls from a weather
balloon at a height of 7,744 ft. If the
equation for height as a function of time
is h(t) = -16t2 + initial height wheret is
time in seconds and h(t) is height in feet,
how many seconds will it take for the
thermometer to hit the ground?
[?] seconds
Answer:
It will take 22 seconds for the thermometer to hit the ground.
Step-by-step explanation:
A thermometer falls from a weather balloon at a height of 7,744 ft.
This means that the initial height is of 7744ft.
h(t) = -16t2 + initial height
So
[tex]h(t) = -16t^2 + 7744[/tex]
How many seconds will it take for the thermometer to hit the ground?
This is t for which [tex]h(t) = 0[/tex]. So
[tex]0 = -16t^2 + 7744[/tex]
[tex]16t^2 = 0 + 7744[/tex]
[tex]t^2 = \frac{7744}{16}[/tex]
[tex]t = \sqrt{\frac{7744}{16}}[/tex]
[tex]t = 22[/tex]
It will take 22 seconds for the thermometer to hit the ground.
Given that the two triangles below are similar , find the values of g and h
Answer:
g = 4
h = 4.5
Step-by-step explanation:
The corresponding sides of two similar figures are proportional to each other.
Therefore,
[tex] \frac{g}{3} = \frac{8}{6} = \frac{6}{h} [/tex]
✔️Find g:
[tex] \frac{g}{3} = \frac{8}{6} [/tex]
Cross multiply
g*6 = 8*3
6g = 24
Divide both sides by 6
g = 24/6
g = 4
✔️Find h:
[tex] \frac{8}{6} = \frac{6}{h} [/tex]
Cross multiply
8*h = 6*6
8h = 36
h = 36/8
h = 4.5

Katie needs 3/4 cup of sugar to make cookies. She only has 1/3 cup. How much more sugar does Katie need?
Answer:
[tex]\frac{5}{12}[/tex] cups
Step-by-step explanation:
This question is asking for the difference between the two values so subtraction is necessary
[tex]\frac{3}{4} -\frac{1}{3}[/tex]
Multiply the top and bottom of the first fraction by 3 and the second one by 4[tex]\frac{3*3}{4*3} -\frac{1*4}{3*4} = \frac{9}{12} -\frac{4}{12}[/tex]
Now just substract
9 - 4 = 5 ==> [tex]\frac{9}{12} -\frac{4}{12} = \frac{5}{12}[/tex]

U +-
The measure of UW is
type your answer...
Answer:
9
Step-by-step explanation:
UT^2 = UV * UW
6^2 = (x - 7)(x - 7 + 5)
36 = (x - 7)(x - 2)
36 = x^2 - 2x - 7x + 14
x^2 - 9x - 22 = 0
(x - 11)(x + 2) = 0
x - 11 = 0 or x + 2 = 0
x = 11
UW = x - 7 + 5
UW = 11 - 7 + 5
UW = 9

The circumference of a circle is 7π in. Find its radius, in inches.
Answer:
3.5 in
Step-by-step explanation:
Circumference = 2π(radius)
7π = 2π (radius)
7π/2π = radius
Pi in numerator and denominator cancel each other.
7/2 = radius
3.2 in = radius
Answer:
[tex] \bf \huge \: 11 \: inches.[/tex]
Step-by-step explanation:
Given :The circumference of a circle is 7π in.to find :Find its radius, in inches.formula used :r = c/2where,
r = radius c = circumference explanation :⟼ r = c/2
⟼ r = 7×22÷7/2 in
⟼ r = 22/2 in
⟼ r = 11 in.
Hence, radius is 11 inches.Page No

The method of tree ring dating gave the following years A.D. for an archaeological excavation site. Assume that the population of x values has an approximately normal distribution
1229 1257 1243 1194 1268 1316 1275 1317 1275
(a) Use a calculator with mean and standard deviation keys to find the sample mean year x and sample standard deviation s. (Round your answers to the nearest whole number.)
(b) Find a 90% confidence interval for the mean of all tree ring dates from this archaeological site. (Round your answers to the nearest whole number.)
Answer:
A) Mean = 1264
Standard deviation = 37
B) CI ≈ (1241, 1287)
Step-by-step explanation:
A) Mean = Σx/n
Σx = 1229 + 1257 + 1243 + 1194 + 1268 + 1316 + 1275 + 1317 + 1275
Σx = 11374
Mean(x¯) = 11374/9
Mean(x¯) ≈ 1264
Standard deviation = √(∑(x - x¯)²/(n)
From online calculator;
Standard deviation; s ≈ 37
B) Our distribution factor is; DF = n - 1 = 9 - 1 = 8
From t-table attached, our critical value at 90% Confidence interval is t = 1.86
Formula for confidence interval is;
CI = x¯ ± t(s/√n)
CI = 1264 ± 1.86(37/√9)
CI = 1264 ± 22.94
CI ≈ (1241, 1287)
