Responder:
2280 pneus.
Explicação passo a passo:
Dado que :
Número máximo de pneus que o caminhão pode transportar de uma vez = 456
Se o caminhão fizer 5 viagens;
O número de pneus que serão transportados na capacidade máxima é:
Capacidade máxima do caminhão * número de viagens
456 * 5
= 2.280 pneus.
Write a SIMPLIFIED inequality for x that would give a rectangle with a length of 4 meters and a width of x+7 meters an area of more than 128 meters squared.
Answer:
128 > 4*(x + 7)
Step-by-step explanation:
Given the following data;
Length = 4 meters
Width = x + 7 meters
Area = 128 m²
Mathematically, the area of a rectangle is given by the formula;
Area of rectangle = length * width
Substituting into the formula, we have;
128 > 4*(x + 7)
128 > 4x + 28
128 - 28 > 4x
100 > 4x
Dividing both sides by 4, we have;
25 > x
When a tree 8m high casts a shadow 3m long, how long is a shadow cast by a person 2m tall?
Answer:
3/4 meters
Step-by-step explanation:
We can use ratios to solve
8m 2 m
------- = -----------
3m x m
Using cross products
8*x = 3*2
Divide each side by 8
8x/8 = 6/8
3/4 meters
Answer:
x = 3/4 m
Step-by-step explanation:
Construct two similar right triangles that share an angle of elevation. The two vertical sides represent the heights of the person and the tree and are 2 m ad 8 m respectively. The two horizontal sides represent the shadow cast by the person and that cast by the tree, respectively. Because the triangles are similar, we can write the following equation of ratios:
8 m 3 m
--------- = --------
2 m x
... where x is the length of the shadow cast by the person.
Cross multiplying, we get:
8x = 6m, or x = 6/8 m, or x = 3/4 m
When you use the distance formula, you are building a right triangle, the of which goes between two given points.

The value of x is
and the value of y is
Answer:
Y = 50 degrees, X = 60 degrees
Step-by-step explanation:
Since we know that the sum of angles in a triangle is 180 degrees, we can find x easily. We already know that the other two angles are 50 and 70, which adds up to 120, and 180 - 120 is equal to 60 degrees, meaning that x is equal to 60 degrees. Next, to find the measure of y, we first know that the sum of angles on a line is equal to 180 degrees, and if we find the other angle on the line by subtracting 60 + 50 from 180, we can find y. 180 - (60 + 50) = 70 degrees, and since 70 + x + y = 180 and x = 60, we know that x = 180 - (70 + 60) = 50. Therefore, y is equal to 50 degrees.

lol i accidentally wrote “decimal” on the other
Step-by-step explanation:
Step 1: Write down the percent divied by 100 like this: percent/100
Step 2: If the percent is not a whole number, then multiple both top and bottom by 10 for every number after the decimal point. (for example, if there is on number after the decimal, then use 10, if there are two then use 100, ect.)
Step 3: simplify.(or reduce) the fraction

An airplane descends 1.6 miles to an elevation of 8.05 miles. Find the elevation of the plane before its descent.
Answer:
9.65 miles
Step-by-step explanation:
Given:
Final elevation = 8.05 miles
Change in elevation = 1.6 miles
Let Initial elevation which is the elevation before descent = x
Initial elevation - change in = final elevation
(-ve) sign because it was a descent
x - 1.6 = 8.05
x = 8.05 + 1.6
x = 9.65 miles
Hence, elevation before descent is 9.65 miles

The sum of the 1st nth term gp is 127.the sum of the reciprocal is 127/64,if the 1st term is 1.find n and the common ratio
Answer:
Ratio (r) = 2
n = 7
Step-by-step explanation:
The formula for the sum of the nth term of a G.P is given as:
Sn = a(1-r^n)/(1-r)
Where n = Number of terms
r = Common ratio
The sum of the 1st nth term gp is 127.
Hence:
127 = 1(1-r^n)/(1-r)
The sum of the reciprocal is 127/64
The formula is inverted , hence:
Sn = 1/a(1-r^n)/(1-r)
127/64 = r^(1-n)(1-r^n)/(1-r)
Hence:
1/64 = r^(1-n)
r^(n-1) = 64
r^(n-1) = 2⁶
Hence:
r = 2
Solving for n
n - 1 = 6
n = 6 + 1
n = 7
Therefore:
r = 2
n = 7

a first number plus twice a second number is 8 twice the first number plus the second totals 25
Answer:
The first number is 14
The second number is -3
Step-by-step explanation:
x + 2y = 8
2x + y = 25
Solving simultaneously,
2x + 4y = 16
2x + y = 25
On subtracting, we have
3y = -9
y = -3
Going to substitute for y, we have
x + 2(-3) = 8
x - 6 = 8
x = 14

The Secant of angle A is -5/4. a) What quadrants could angle A be in? b) Determine the measure(s) of angle A
Answer:
a) 2nd and 3rd quadrant
b) 143.13° and 36.87°
Step-by-step explanation:
Secant A = 1/cosecant A
sec A = 1/cosA
If Sec A = -5/4
Cos A = 1/(-5/4)
CosA = -4/5
Since cos A is a negative values, hence the angle A will be in the 2nd and 3rd quadrant
b) If CosA = -4/5
A = arccos(-0.8)
A = 143.13
A = 180 - 143.13
A = 36.87
Hence the measures of angle A are 143.13° and 36.87°

2. The volume of a cylinder is 95 cubic centimeters. Which equation
can be used to find h, the height of the cylinderę Circle the correct
answer.
Given:
The volume of a cylinder is 95 cubic centimetres.
To find:
The equation that can be used to find h, the height of the cylinder.
Solution:
We know that, the volume of a cylinder is:
[tex]V=\pi r^2h[/tex]
We know that the base of the cylinder is a circle and the area of the circle is [tex]\pi r^2[/tex]. So, the base area of the cylinder is [tex]B=\pi r^2[/tex].
Now, volume of the cylinder is
[tex]V=Bh[/tex]
The volume of a cylinder is 95 cubic centimetres.
[tex]95=Bh[/tex]
[tex]\dfrac{95}{B}=h[/tex]
[tex]h=\dfrac{95}{B}[/tex]
Where B is the base area of the cylinder.
Therefore, the correct option is G.

Granny needs to paint a Loge made using two right triangles the dimensions Of the loge are shown below what is the difference between the area of the large triangle in the area of a small triangle
Answer:
The difference is
Step-by-step explanation:
Given
Large triangle
[tex]Base = 5cm; Height=9cm[/tex]
Small triangle
[tex]Base = 2cm; Height=6cm[/tex]
See attachment for logo
Required
The difference in their areas
Area is calculated as:
[tex]Area = 0.5 * base * height[/tex]
For the large triangle
[tex]Area = 0.5 * 5cm * 9cm[/tex]
[tex]Area = 22.5cm^2[/tex]
For the small triangle
[tex]Area = 0.5 * 2cm * 6cm[/tex]
[tex]Area = 6cm^2[/tex]
The difference (d) is calculated as:
[tex]d = 22.5cm^2 - 6cm^2[/tex]
[tex]d = 16.5cm^2[/tex]

if 4.5kg sugar cost R36 what will 2.5kg cost
Answer:
Step-by-step explanation:
Find the unit rate of Sugar. Then find the cost of 2.5 Kg sugar
1 kg sugar =36 ÷ 4.5
[tex]= \frac{36*10}{4.5*10}= \frac{360}{45}\\\\= 8[/tex]
2.5 kg of sugar= 2.5 * 8 = 20.0 = R 20
Answer:
Kg Rupee
4.5 = 36
2.5 = ?
Therefore, 2.5*36/4.5
Therefore, 25*36*10/45*10
Therefore, 25*36/45
Therefore, 5*5*36/9*5
Therefore, 5*36/9
Therefore, 5*3*2*3*2/3*3
Therefore, 5*2*2
Therefore, 10*2
Therefore, 20
2.5 kg =20 Rupees

2. Dianna can carry up to 15 lbs in her backpack.
Her lunch weighs 1 lb, her gym shoes weigh
2 lbs, and her books weigh 1.5 lbs each. Which
inequality shows how many books Dianna can
carry in her bag if she has her lunch and gym
shoes?
O A. 3 + 1.5b < 15
B. 1.5 + 3b < 15
C. 3 + 1.5b > 15
D. 1.5 + 3b < 15
Answer:
Answer is A. 3 + 1.5 b < 15.
Step-by-step explanation:
Look at the problem carefully. Variable (b) represents books, and it states that the books weigh 1.5 lbs each. So you add her lunch (1 lb) and her shoes (2 lbs) to get 3 lbs. Once you add it together, it's less than (<) 15 lbs.
